本発明の方法は、
一般式
The present invention relates to a method for manufacturing a thermosetting resin laminate with excellent heat resistance. (In the formula, X represents a halogen atom, m is 1 to 2,
n is an integer of 1 to 2. R 1 represents an alkylidene group or an alkylene group having 1 to 4 carbon atoms. ) Halogenated dihydroxy compound (A)
and general formula (In the formula, X represents a halogen atom, l is an integer of 1 to 3, and R2 represents H or an alkyl group having 1 to 4 carbon atoms.) A halogenated monoglycidyl ether (B) represented by A product with a molecular weight of 700 to 1400 reacted at a ratio of 1 to 3 moles of B per mole has the general formula (In the formula, X represents a halogen atom, o is 0 to 2,
p is an integer from 0 to 2. R 3 is an alkylidene group or alkylene group having 1 to 4 carbon atoms. Q indicates 0-4. ) Diglycidyl ether compound (C)
is further reacted at a ratio of 0.1 to 1.0 mole of C to 1 mole of A, and then a flame retardant for synthetic resins is further reacted at a ratio of 0.01 to 0.30 mole of phenol to 1 mole of A. The present invention relates to a method for manufacturing a laminate, which comprises impregnating a base material for a laminate with a thermosetting resin composition, drying, and then heating and pressing the composition. The purpose of this study is that laminates that are thermally stable and have high heat resistance, as seen in conventional laminates containing flame retardants for synthetic resins, have low flame resistance, and conversely, those that have excellent flame resistance have low heat resistance. Even if they are thermally stable, they often color the product or give it a bad odor, or have poor processability due to low adhesion between base material layers.
The present invention relates to a method for producing a thermosetting resin laminate that has excellent processability, is free from bad odor and coloring, and has extremely excellent flame resistance. Due to the remarkable development of petrochemistry, the production of synthetic resins derived from this has become enormous.Synthetic resins have been used in a wide range of areas by skillfully utilizing their excellent properties, and will continue to be used in a wide range of areas. Although their uses are becoming more widespread, strict regulations have been put in place due to the disadvantage that synthetic resins are easily flammable. The UL standard described herein is one of them. UL is a public safety organization called Underwriters Laboratories, Inc., and its No. 94 is the Flammability Standard for Plastic Materials (UL-94). The flame retardant evaluation stipulated in the same standard is rated in the order of 94V-0, 94V-1, 94V-2, and 94HB depending on the degree of flame retardancy. The test method is to prepare 5 test pieces of a specified size, clamp the upper end of the test piece, set the test piece vertically, apply a burner flame of a specified length to the lower end for 10 seconds, and then perform the test. Measure the burning time of the pieces. Immediately after extinguishing the fire, apply the flame again for 10 seconds and measure the burning time. Let T be the total burning time of the test of 5 pieces, and let M be the maximum value. If T is 50 seconds or less and M is 10 seconds or less, the flame will not burn to the clamp, and the flaming molten material will fall and cause the cotton below the specified level to burn. If it does not ignite, it is UL94V-0. T is 250 seconds or less, M is 30 seconds or less, and other values are V.
UL94V-1 if the same conditions as -0 are met. If T and M are similar to V-1 and a flaming molten material falls and ignites cotton, it is UL94V-2. V-0,V
-1 and V-2, a horizontal combustion test is conducted for those that fail, and if the fire is extinguished before the designated marking line, it will be evaluated as UL-94HB. As a trend in the world, requirements for flame retardancy have become stricter year by year, and at present, most products require UL94V-0.
On the other hand, flame retardant synthetic resins are made using halogen compounds,
This has been achieved through the synergistic effect of combinations of phosphorus compounds, nitrogen compounds, or metal oxides, but
Adding a flame retardant to a synthetic resin improves flame retardancy, but on the contrary, various properties such as heat resistance, mechanical properties, electrical properties, and processability inevitably deteriorate. Therefore, there has been a strong demand for flame retardant methods and flame retardant thermosetting resin laminates that minimize deterioration of these properties. Conventionally, various improvements have been made to halogen compounds, which have the greatest flame retardant effect and are essential as flame retardant components. For example, in Japanese Patent Publication No. 47-44537, the formula (In the formula, R is H or a lower alkyl group) In JP-A No. 53-56290, the compound represented by the formula In JP-A-56-118414, the compound represented by the formula (In the formula, Z is -CH 2 OH or halogen, X is halogen, R is H or a hydrocarbon group, Y and Y' are H
or CH 3 , T.T' is -CH 2 CH 2 O-, etc.). All of these flame-retardant compounds have a large number of aromatic rings and are therefore quite thermally stable, and laminates made of thermosetting resins containing these compounds have considerably excellent heat resistance. . However, the flame-retardant compound obtained in Japanese Patent Publication No. 47-44537 was itself very rigid, resulting in hard laminates and poor workability. Furthermore, the flame retardant compound obtained in JP-A-53-56290 did not have a sufficient flame retardant effect because the bromine content was as low as 40% or less. Furthermore, the flame retardant compound obtained in JP-A No. 56-118414 was itself very flexible and could be made into a laminate, but due to its low adhesive strength, delamination occurred during punching. . The present inventors discovered that although thermosetting resins have excellent mechanical properties, electrical properties, heat resistance, water resistance, chemical resistance, moldability, processability, etc., there is no excellent flame retardant. The present invention has been completed as a result of intensive research into ways to eliminate the various drawbacks of laminates using conventionally known flame retardants. In other words, the advantage of the present invention is that halogen compounds are used more frequently as raw materials than conventionally known flame retardants, so the resulting flame retardant has a high halogen content. Just adding it can provide sufficient flame retardancy, and since the amount added is small, there is almost no effect on other properties such as deterioration of mechanical properties, deterioration of electrical properties, or deterioration of workability as a laminate. be. Another advantage of the present invention is that the new flame retardant contains many aromatic rings in its molecular structure, so it has a high thermal decomposition temperature and is thermally stable. It must not have any adverse effects such as reducing the heat resistance of the plate. Furthermore, because the decomposition temperature is high, there is almost no discoloration or off-odor.

を第1表に示した。[Formula] (In the formula, X represents a halogen atom, l is an integer of 1 to 3, and R2 represents H or an alkyl group having 1 to 4 carbon atoms.) A halogenated monoglycidyl ether (B) represented by is reacted at a ratio of 1 to 3 moles of B to 1 mole of A to a product with a molecular weight of 700 to 1400, and the general formula (In the formula, X represents a halogen atom, o is 0 to 2,
p is an integer from 0 to 2. R 3 is an alkylidene group or alkylene group having 1 to 4 carbon atoms. Q indicates 0-4. ) Diglycidyl ether compound (C)
is further reacted at a ratio of 0.1 to 1.0 mole of C to 1 mole of A, and then a flame retardant for synthetic resins is further reacted at a ratio of 0.01 to 0.30 mole of phenol to 1 mole of A. The present invention relates to a method for manufacturing a laminate, which comprises impregnating a base material for a laminate with a thermosetting resin composition, drying, and then heating and pressing the composition. The flame retardant according to the present invention will be specifically shown in the experimental examples described below, but can be represented by the following general formula as a model. i.e. (In the formula, X represents a halogen atom, l is 1 to 3,
m is an integer of 1 to 2, and n is an integer of 1 to 2. R 1 is carbon number 1
~4 alkylidene group or alkylene group
R 2 represents H or an alkyl group having 1 to 4 carbon atoms. ) In the present invention, the ratio of reaction between the halogenated dihydroxy compound and the halogenated monoglycidyl ether is ideally 1 mol of the former to 2 mol of the latter, and in this case, the flame retardant effect is the greatest and the heat resistance is also high. It was. This is the molecular structure of the former OH
This is thought to be due to the complete processing of the groups and increased thermal stability. However, in reality, even if 2 moles or more than 2 moles of halogenated monoglycidyl ether are reacted with 1 mole of the halogenated dihydroxy compound, a considerable amount of a compound in which 1 mole of the latter is added to 1 mole of the former is produced. It was not possible to completely treat the former OH group.
Therefore, next, a small amount of diglycidyl ether compound was further added and reacted to completely treat the OH groups. Because diglycidyl ether compounds have high reaction activity, they can completely eliminate unreacted residual OH groups caused by halogenated dihydroxy compounds. However, due to their high activity, it is difficult to control the reaction, resulting in abnormally high It may become molecular. Therefore, we subsequently added a small amount of phenol and caused a reaction to block the highly active diglycidyl ether residues, thereby making it possible to obtain a product with a molecular weight that exhibits the highest flame retardant effect. In the present invention, the reaction charge ratio of halogenated monoglycidyl ether to 1 mol of halogenated dihydroxy compound is preferably 2 to 2.5 mol,
Practically speaking, even those prepared and reacted at a ratio of 1 to 3 moles were considerably superior to conventionally known flame retardants. When it was less than 1 mole, thermal stability was poor, causing bad odor and discoloration, and when it was more than 3 moles, flame resistance decreased. Further, the reaction charge ratio of diglycidyl ether to be further reacted with this is preferably 0.3 to 0.7 mol, but may be 0.1 to 1.0 mol for practical purposes.
If it is less than 0.1 mol, the amount necessary to treat OH groups will be insufficient, and if it is more than 1.0 mol, there is a risk of gelation. Further, the reaction charge ratio of phenol to be further reacted is preferably 0.01 to 0.30 mol.
If it is less than 0.01 mol, the amount necessary to block diglycidyl ether groups will be insufficient, and if it is more than 0.30 mol, the properties of the laminate will deteriorate. As a method for reacting a dihydroxy compound and glycidyl ether in the present invention,
48-6639, this method involves reacting 2 moles of low molecular weight diglycidyl ether with 1 mole of dihydroxy compound to produce high molecular weight diglycidyl ether, and the product is further reacted. It has a reactive group that can The method of the present invention is not a diglycidyl ether, but a low molecular weight compound obtained by reacting 2 moles of monoglycidyl ether with 1 mole of a dihydroxy compound, and this compound no longer has a reactive group. Of course, in the detailed description of the invention in Japanese Patent Publication No. 48-6639, it is stated that monoglycidyl ether may be used as the glycidyl ether, but
Its purpose is as an auxiliary raw material as a reaction terminator or reaction regulator, and the amount added in the examples is only 5% or less of the total. This is because if a large amount is used, the purpose of increasing the molecular weight cannot be achieved, and the invention described in Japanese Patent Publication No. 48-6639 cannot be achieved with monoglycidyl ether alone, as in the present invention. The method of reacting the dihydroxy compound, monoglycidyl ether, and diglycidyl ether compound in the present invention is also described in JP-A-53-42298, but this method A flame-retardant resin composition is created by simultaneously mixing and reacting a resin and a bifunctional epoxy resin. Although this known document does not explain the role and effect of each ingredient, in the synthesis example, if the amount of monofunctional epoxy resin added is large, the softening point of the product will be low, and if it is small, the softening point will be high. Therefore, it is thought that monofunctional epoxy resins are used as reaction regulators or reaction terminators.
In this sense, it is very similar to Japanese Patent Publication No. 48-6639. In addition, in this known document, each ingredient is mixed and reacted all at once, but the product produced by this method is a reaction in which monofunctional and difunctional epoxy resins randomly react with difunctional phenols, resulting in a combination of difunctional and difunctional epoxy resins. This creates a very dangerous product, such as high molecular weight due to epoxy resin and residual unreacted OH groups of difunctional phenols. The method of reacting a dihydroxy compound, monoglycidyl ether, diglycidyl ether compound, and phenol in the present invention involves the first step of preparing a low molecular weight compound of a dihydroxy compound and monoglycidyl ether, and then reacting the low molecular weight compound with a diglycidyl ether compound. A second step in which the unreacted OH groups of the dihydroxy compound remaining in the molecular weight compound are completely eliminated in order to further improve the thermal stability of the flame retardant of the present invention and prevent bad odor and discoloration; The third step consists of blocking the unreacted diglycidyl ether groups of the diglycidyl ether compound with phenol so that the flame retardant of the present invention does not have an abnormally high molecular weight. is one of the important points. Further, in the present invention, monoglycidyl ether is one of the main raw materials, and rather, the diglycidyl ether compound is an auxiliary raw material.

It was an excellent laminate with high heat resistance, good mechanical properties, good electrical properties, and workability, and no discoloration or strange odor. The present invention will be explained in detail using experimental examples below.

The mixture was placed in a three-four neck flask equipped with a tube, a thermometer, and a dropping funnel, and 200 ml of toluene was added thereto and stirred to form a suspension. Next, 2.2 mol of dibromocresyl monoglycidyl ether was dissolved in 200 ml of toluene,

に示す結果を得た。[Table] As shown in Table 1, the laminate made from the oil-modified phenolic resin containing the flame retardant according to the present invention is
It was an excellent heat-resistant laminate that passed UL-94/V-0. Moreover, the product of the present invention has high soldering heat resistance.
It had high insulation resistance, good punching workability, and no strange odor or discoloration. This is considered to be because the flame retardant used in the present invention has good compatibility and adhesion with the resin and substrate, and has a high thermal decomposition temperature. On the other hand, the laminate prepared by blending flame retardant A had good heat resistance, but due to the low thermal decomposition temperature, gas was generated and all performances including soldering heat resistance were poor. Furthermore, the laminates prepared by blending flame retardants B and C had excellent properties such as soldering heat resistance, but were poor in the most important flame resistance. As described above, the laminate produced by blending the flame retardant of the present invention was an excellent laminate with excellent flame resistance and soldering heat resistance, and a good balance of other properties. Experimental Example 2 In Experimental Example 1, 2.2 mol of dibromucresyl monoglycidyl ether was changed to 0.5 to 3.5 mol of dibromphenyl monoglycidyl ether, 0.2 mol of phenol was changed to 0.1 mol of p-cresol, and the oil-modified phenol resin was changed to polybutadiene. The formulations and tests were carried out in exactly the same manner except that the resin was changed, and the results shown in Table 2 were obtained.

結果を得た。[Table] As shown in Table 2, the laminates (Nos. 3, 4, 5, 6) made by blending the flame retardant synthesized at the preferred reaction charge ratio in the present invention have flame resistance, soldering heat resistance,
The insulation resistance was excellent, the punching workability was also good, and there was no strange odor or discoloration. On the other hand, 2,2-bis(4-hydroxy-3,5-dibromphenyl)
The laminate (No. 2) containing a flame retardant with a small amount of dibromophenyl monoglycidyl ether reacting with propane has poor soldering heat resistance due to a large amount of pyrolysis gas, emits a strange odor, and discolors. Also, the gas causes peeling and the punching processability is not good. On the other hand, the laminate (No. 7) made by blending a flame retardant with a large amount of dibromo phenyl monoglycidyl ether reacted with it did not have good compatibility with the base material, so it was necessary to fully impregnate the base material. However, it did not pass UL-94/V-0 flame resistance, and it peeled off easily due to poor adhesion to the base material, resulting in poor punching workability. Experimental Example 3 In Experimental Example 1, 0.6 mole of bisphenol A diglycidyl ether was changed from 0.05 to 2.0 mole of bisphenol F diglycidyl ether, and phenol

It had excellent heat resistance and insulation resistance, good punching workability, and no strange odor or discoloration. On the other hand, 2,2
- When the amount of bisphenol F diglycidyl ether charged to the reaction product of bis(4-hydroxy-3,5-dibromophenyl)propane and dibromocresyl monoglycidyl ether is small, OH groups remaining in the reaction product The laminate containing this flame retardant (No. 1) was easily thermally decomposed and had low soldering heat resistance. If the amount of bisphenol F diglycidyl ether is increased, OH groups will be eliminated and the soldering heat resistance will be improved, but if it is increased excessively (No. 10), the amount of bisphenol F diglycidyl ether will increase and the amount of bisphenol F diglycidyl ether will increase. Flame resistance decreases due to poor impregnation into the substrate due to decreased bromine content and increased molecular weight. If the amount of bisphenol F diglycidyl ether charged was further increased (No. 11), the molecular weight would abnormally increase and gelation would occur during the reaction. A preferred reaction charge ratio in the present invention is 2,2-bis(4-hydroxy-3,5-dibromphenyl)
The amount of bisphenol F diglycidyl ether is 0.1 to 1.0 mol per mol of propane. When the amount of nonylphenol charged to the reaction product of 2,2-bis(4-hydroxy-3,5-dibromophenyl)propane, dibromocresyl monoglycidyl ether, and bisphenol F diglycidyl ether is small, the final reaction product Unreacted glycidyl ether groups based on bisphenol F diglycidyl ether remain and polymerize,
The molecular weight increased significantly, and the laminate containing this flame retardant (No. 4) had poor impregnation into the base material, resulting in a decrease in flame resistance, electrical insulation, etc. On the other hand, when the amount of nonylphenol charged is large (No. 8)
In this case, unreacted nonylphenol adversely affects soldering heat resistance, insulation resistance, punching workability, etc. A preferred reaction charge ratio in the present invention is nonylphenol to 1 mole of 2,2-bis(4-hydroxy-3,5-dibromphenyl)propane.
It is 0.01-0.30 mole. As is clear from the above experimental examples, the laminate made of the thermosetting resin composition containing the flame retardant of the present invention has excellent flame resistance, good soldering heat resistance,
It was an excellent laminate with high insulation resistance, good punching workability, and no strange odor or discoloration.
