、施工性に極めて難があるという問題があった。BACKGROUND OF THE INVENTION It is desired to improve the quality of large substrate surfaces such as floor panels, dash panels, wheel houses, ceiling panels, etc. of vehicles by increasing their rigidity from the viewpoints of vibration control and improved solidity. This will be explained in more detail. It is desired that automobiles be made lighter from the viewpoint of environmental protection such as carbon dioxide emission regulations and resource conservation. In this regard, countermeasures have been taken such as reducing the thickness of the material and reducing the number of structural members. This decrease in strength leads to a lack of surface tension and rigidity, leading to problems such as a lack of solidity as a member. In order to solve this problem,
The publication proposes a method using a reinforcing material for the door panel. However, this method not only does not provide sufficient rigidity, but also requires a lot of manual installation work, making it extremely difficult to install.

There was a problem that there was a risk. Under these circumstances, the present invention can provide a vehicle structure that is lightweight and has high rigidity, and has a composition that has good heat resistance and can withstand, for example, an electrodeposition coating process. The object is to provide a rigid structure for a vehicle.

A high-temperature decomposition type blowing agent of °C is used. As such a high temperature decomposition type foaming agent, an organic foaming agent, an inorganic foaming agent, a high temperature expansion type capsule, etc. can be used. If the decomposition gas generation temperature is below 100°C, foaming may begin during the processing of semi-gel sheets, which will be described later, or gas may escape due to insufficient melting of the resin during foaming in the heating furnace, and the foaming ratio may not be large. Or it is difficult to obtain a homogeneous foam. Furthermore, if the temperature exceeds 220° C., the processing temperature of the composition becomes high and the resin deteriorates, making it difficult to obtain a foam of good quality. Examples of such organic blowing agents include azodicarbonamide, p-toluenesulfonyl hydrazide, dinitrosopentamethylenetetramine, 4,4'-
Examples include oxybisbenzenesulfonyl hydrazide. The decomposition temperature of these organic blowing agents can be easily adjusted by adding urea, zinc compounds, lead compounds, etc. Examples of inorganic blowing agents include sodium hydrogen carbonate and potassium borohydride, and examples of high-temperature expansion microcapsules include those obtained by encapsulating low-boiling hydrocarbons with vinylidene chloride resin.

噴霧して均一に乾燥吸着させて用いるのが有利である。In the spacer composition of the present invention, a surfactant is used as component (D). This surfactant has the role of improving the cell structure. Examples of the surfactant include alkyl sulfate salts such as sodium lauryl sulfate and sodium myristyl sulfate, alkylaryl sulfonates such as sodium dodecylbenzenesulfonate and potassium dodecylbenzenesulfonate, sodium dioctylsulfosuccinate, Preferred examples include sulfosuccinic acid ester salts such as sodium dihexyl sulfosuccinate, fatty acid salts such as ammonium laurate and potassium stearate, anionic surfactants such as polyoxyethylene aryl sulfate ester salts and rosinate salts. In addition, sorbitan esters such as sorbitan monooleate and polyoxyethylene sorbitan monostearate, nonionic surfactants such as polyoxyethylene ethers, polyoxyethylene alkylphenyl ethers, and polyoxyethylene alkyl esters, cetylpyridinium chloride, Cationic surfactants such as cetyltrimethylammonium bromide can also be used. These surfactants may be used alone or in combination of two or more. The amount added is selected within the range of 0.05 to 5 parts by weight, preferably 0.2 to 3 parts by weight, per 100 parts by weight of the liquid epoxy resin (A). If it is less than 0.05 parts by weight, it cannot play the role of improving the cell structure, and even if it is more than 3 parts by weight,
However, the stability of the cell is not improved, and in some cases, it may cause discoloration due to decomposition during heating. As for the method of adding the surfactant, when the rubber elastic body or thermoplastic resin used as component (E) is in powder form, it is advantageous to spray it in advance and dry and adsorb it uniformly before use.

たりする不都合が生じる。The spacer composition (E) of the present invention contains a rubber elastic material or a halogen that is insoluble in the epoxy resin (A) at room temperature and can be mixed and dispersed with the epoxy resin at a temperature of 80 to 150°C. No thermoplastic resin can be used. In this case, the rubber elastic body can be used not only in solid form but also in viscous liquid form, while the thermoplastic resin composition must be in powder form with an average particle size of 150 μm or less. When this rubber elastic body or thermoplastic resin is heated to 150°C or higher,
It is desirable to use a material that melts to form a homogeneous affinity with the epoxy resin of component (A) and maintains the melt viscosity of the composition stably, such as chloroprene rubber, butadiene-acrylonitrile rubber, Rubber elastic bodies such as carboxyl-modified butadiene-acrylonitrile rubber, epoxy-modified butadiene-acrylonitrile rubber, butadiene rubber, isoprene rubber, ethylene-vinyl acetate copolymer, polyphenylene ether, ethylene-vinyl alcohol copolymer, acrylonitrile-styrene copolymer , polyamide, polyvinyl butyral, polyvinyl acetal, polymethyl methacrylate, acrylonitrile-butadiene-styrene copolymer, methyl methacrylate-butadiene-styrene copolymer, polystyrene, and the like. These may be used alone or in combination of two or more. The component (E) has the function of adjusting the melt viscosity of the composition, and also has the function of improving the toughness of the obtained foam. The amount of component (E) added is selected within the range of 10 to 200 parts by weight per 100 parts by weight of the liquid epoxy resin of component (A). It depends on the type of rubber elastic body or halogen-free thermoplastic resin added, but if it is less than 10 parts by weight, there is no function to adjust the melt viscosity or to improve the toughness of the foam, and on the other hand, if it is more than 200 parts by weight, Although this also depends on the type of rubber elastic body or thermoplastic resin, disadvantages arise in that the expansion ratio of the foam does not improve or the rigidity of the foam decreases.

使用することができる。In the composition of the present invention, it is important to balance the affinity between the epoxy resin as the component (A) and the rubber elastic material and thermoplastic resin as the component (E). It is necessary to appropriately select the particle size, amount added, etc. In particular, in terms of affinity balance, a system in which polymers are completely compatible with each other during melting is not desirable;
It is desirable to be in a stable dispersed mixture state. Therefore, depending on the combination of polymers, it is desirable to add a plasticizer to increase the mutual affinity and thereby adjust the affinity of the polymer tube. This plasticizer also has the function of adjusting melt viscosity, and examples of the plasticizer include phthalate esters such as dioctyl phthalate and dibutyl phthalate, phosphate esters such as tricresyl phosphate, dioctyl adipate, etc. Further, conventionally known fatty acid esters such as adipic acid condensates of ethylene glycol, trimellitic acid esters, glycolic acid esters, chlorinated paraffins, and alkylbenzenes can be used.

発泡性状が得られなくなる。The spacer composition of the present invention contains the essential components (A), (B), (C), (D) and (E) and various additive components used as desired. It can be adjusted using a quantitative method, for example, a planetary mixer, kneader, roll, Henschel mixer, etc. The spacer composition of the present invention prepared in this manner has a melt viscosity of 2.5 x 103 to 5 x 104 dP at the decomposition gas generation temperature of the blowing agent contained therein.
a. It is preferably in the range of s. If the melt viscosity is outside the above range, it will be difficult to obtain a foam with a good appearance, an expansion ratio of 5 times or more, and an average cell diameter of 0.5 mm or less. Further, in the structure of the present invention, this spacer composition is used in the form of a semi-gelled sheet. That is, the prepared composition is preformed into a sheet at a temperature below the decomposition temperature of the blowing agent,
After that, the upper layer sheet (2) made of a restraining material is laminated, and then in the next heating step, for example, a painting drying step,
It foams at 0°C to 200°C and is cured by crosslinking of the epoxy resin. The expansion ratio of such a lower sheet is 2 to 30 times, preferably 5 to 10 times. A foam with a foaming ratio of 2 times or less can of course function as a spacer, but this is not the purpose of the present invention from the viewpoint of light weight, and if the foaming ratio is 30 times or more, the strength of the foam cells will be insufficient and the vehicle will be damaged. There may be problems with durability depending on where it is used. Further, the thickness of the lower layer sheet after foaming is 1 to 50 mm, preferably 3 to 30 mm. If it is less than 1 mm, it will not function effectively as a spacer, and if it is more than 50 mm, it will become impractical in vehicle applications, which is the purpose of the present invention, because the interior space of the vehicle will become narrow and heating processes such as drying processes will be difficult. In this case, homogeneous foaming properties cannot be obtained.

である。II. Test method Lower layer sheet and upper layer sheet each 15 x 300 mm,
A structure was created by combining a steel plate with a thickness of 0.8 mm, and the rigidity ratio of each structure was measured at 20, 40, and 60°C. Lamination and foaming of each layer is done after placing each layer on a steel plate.
Heat treatment was performed in an oven under the conditions of 30 minutes at °C. The stiffness ratio was calculated from the moving frequency of the resonance point of the mechanical impedance using Equation 1 below, and the stiffness ratio at 200 Hz was determined by interpolation. In addition, the measurement frequency is 1 to 1000Hz

2 is the areal density of the lower sheet and the upper sheet. In addition, the followability to the uneven shape was determined by cutting out the material of the lower layer sheet and the upper layer sheet mentioned above to a width of 20 mm and a length of 250 mm, respectively, and corrugating the uneven shape shown in FIG. 1 (A) front view and (B) side view. A heating test was conducted in an oven on a steel plate with a height of 7.8 mm perpendicular to the wave shape, and the followability was observed. The heating conditions are the same as in the case of bonding. The evaluation was as follows: "○" indicates that the products are in close contact with each other without any gaps, "△" indicates that some gaps remain but are acceptable for use, and "x" indicates that the gaps remain and pose a problem in use. In addition, the uniformity of foam cells can be determined by observing their appearance.
The foaming ratio was classified into four levels: ○, △, and ×, and the foaming ratio was measured. Table 4 shows the results of the followability and foaming properties of the examples, and Table 5 shows the results of the comparative examples. As shown in Table 4, the rigid structures according to the present invention in Examples 1 to 6 had good foamability, rigidity, and unevenness followability, whereas in the comparative examples shown in Table 5, The structures of Examples 1 and 2 are significantly inferior in foamability, and the structures of Comparative Example 3 and structures are significantly inferior in rigidity.
