The present invention relates to a hot melt composition with improved adhesion and heat resistance stability, and more specifically, the present invention relates to a hot melt composition having improved adhesiveness and heat resistance stability, and more specifically, the composition contains an ethylene copolymer and/or waxes and a resin component as essential components, and the resin component is formed by thermal decomposition of petroleum. This hot melt composition is an aromatic resin obtained by polymerizing a specific fraction of the obtained cracked oil fraction, and is an extremely excellent hot melt composition with improved adhesiveness, heat resistance stability, and low temperature properties. relating to things. In recent years, hot-melt compositions, a typical hot-melt adhesive, are 100% solid and have many advantages, such as less risk of fire, reduced adhesive set time, and ease of handling. With the rapid spread of applicators, it is used in a wide range of fields such as bookbinding, packaging, and woodworking. Hot melt adhesive is an adhesive that is solid at room temperature, and when used, it is melted by heat, applied to various base materials, bonded, and solidified by cooling.
It develops adhesive strength. For this reason, hot melt adhesives must have excellent adhesion to various base materials, and in order to obtain products of consistent quality, they must have excellent heat resistance stability.
Furthermore, depending on the application, flexibility is required even at low temperatures. Currently, the base polymers for these hot melt adhesives include ethylene copolymers such as ethylene-vinyl acetate copolymer (EVA) and ethylene-acrylate copolymer, polyethylene, thermoplastic rubber, polyamide, polyurethane, and polyester. Thermoplastic polymer substances are used, and adhesion and melt viscosity are improved by blending them with tackifying resins, various low molecular weight thermoplastic resins as viscosity modifiers, and various waxes. As a base polymer, it is particularly useful because it is inexpensive, has excellent flexibility, and has excellent heat resistance stability.
Ethylene-based copolymers such as EVA and ethylene-acrylate are widely used. Natural resins such as rosin and terpene resins, as well as various petroleum resins, are used as tackifying resins.Rosin resins in particular have excellent adhesive strength and flexibility at low temperatures, while terpene resins have excellent heat resistance and stability. Although they are widely used due to their excellent properties, they are expensive because they are all made from natural materials, and there are resource issues. In addition, various petroleum resins made from inexpensive petroleum fractions have been proposed and used as alternatives to rosin and terpene resins, but none of them have the same advantages as rosin in terms of adhesion, heat stability, and low-temperature properties. Nothing comparable to terpene resins has been proposed to date. The present invention provides a hot-melt composition containing a tackifying resin synthesized mainly from abundant and inexpensive industrial raw materials, which has performance equivalent to or superior to hot-melt adhesives made of rosin, terpene resin, etc. The purpose is to provide an extremely excellent hot melt composition. That is, the present invention provides a hot melt composition containing a tackifying resin and an ethylene copolymer as main components, in which the tackifying resin component has a boiling point of 145 to 220°C among cracked oil fractions obtained by thermal decomposition of petroleum. By distilling a fraction having a range, the conjugated diolefin content is 0.7 wt% or less, the conjugated diolefin content is 3% or less, and the total content of indene and its alkyl derivatives is 2 wt% or less. At least one member selected from tetrahydroindene, methyltetrahydroindene, vinylcyclohexene, and vinylnorbornene is added to 100 parts by weight of the distillate prepared under conditions where the vinyltoluene content is 8% or less and the vinyltoluene content is 60 to 90%. An aromatic type with a softening point of 60 to 120°C obtained by polymerizing 5 to 50 parts by weight of a raw material oil using a Friedel-Crafts catalyst in the presence of 0.1 to 3.0 parts by weight of phenols. The present invention provides a hot melt composition characterized in that it is a resin. Further, the present invention provides an excellent hot melt composition which further contains waxes in addition to these main ingredients. The composition of the present invention has far superior performance in terms of adhesiveness, heat resistance stability, and low temperature properties compared to conventional hot melt compositions using petroleum resins.
In addition, it has extremely excellent performance that is comparable to or even better than natural resins such as rosin and terpene. The ethylene-based copolymer in the present invention is a copolymer of ethylene and one or more of monocarboxylic acid vinyl esters such as vinyl acetate, acrylic acid, and acrylic acid esters as a copolymerization component, and the copolymer The copolymerization component content in the product is 10 to 60% by weight, preferably 15 to 45% by weight, and the melt index (MI) is 0.1 to 1000, preferably 1 to 1000.
It is 500. Here, the melt index refers to the number of grams flowing out in 10 minutes at 190°C and a load of 2160g according to ASTMD-1238. The waxes used in the composition of the present invention include petroleum waxes such as paraffin wax and microcrystalline wax, natural waxes, polyethylene waxes, polypropylene waxes, and atactic polypropylene waxes depending on the purpose. Can be used as appropriate. The tackifier resin component in the present invention is comprised of 145 to 220% of the cracked oil fraction obtained by thermal decomposition of petroleum.
A fraction with predetermined properties obtained by distilling a fraction having a boiling point within the range of °C and a fraction selected from tetrahydroindene, methyltetrahydroindene, vinylcyclohexene, and vinylnorbornene (hereinafter referred to as component (b)). It is an aromatic resin obtained by polymerizing at least one type of phenol and phenols as raw materials. Generally, petroleum-based hydrocarbon resins are obtained by polymerizing cracked oil fractions that are liquid at room temperature, obtained by thermal decomposition of petroleum, and their boiling points range from 20â to 280â,
The raw material oil is a fraction having a boiling point in a wide range from 145°C to 280°C. boiling point range
When a cracked oil fraction of about 20°C to 140°C is used as a raw material, the resulting resin is a so-called non-aromatic hydrocarbon resin that does not contain aromatic nuclei. In this case, since the raw material oil contains a large amount of conjugated diolefin and non-conjugated diolefin, the resin has a high degree of unsaturation and has poor hue and heat resistance stability. On the other hand, if a cracked oil fraction with a boiling point range of 145°C to 280°C is used as a raw material, the resin obtained will be an aromatic resin, but in this case also, the heat resistance stability,
The hue is not sufficient, and the adhesive properties when used as a hot-melt adhesive are also poor. As a result of a detailed study of the characteristics of each component in the raw oil, the present inventors found that a resin with good adhesiveness and heat resistance stability was obtained from the fraction obtained by strictly distilling specific components in the raw oil, as described below. The inventors have discovered that by employing this resin as a tackifying resin, a hot-melt adhesive with extremely excellent performance can be obtained, and have completed the present invention. The cracked oil fraction, which is one of the starting raw materials for obtaining the tackifier resin according to the present invention, is a petroleum fraction such as naphtha, kerosene or light oil fraction, which is produced by thermal decomposition such as steam cracking to produce ethylene, propylene, butene, etc. It is a cracked oil fraction with a boiling point range of 145°C to 220°C, which is a by-product obtained when producing butadienes and butadienes. As a result of analyzing each component of the cracked oil of the fraction in this boiling point range by gas chromatography, as shown in Table 1, each component typically having the following boiling points was detected.

The sum of indene and its derivatives is the polymerizable component. Furthermore, as shown in Notes 1 and 2 of the above table, if cyclopentadiene and methylcyclopentadiene are produced by heating or the like and are contained in the raw oil, these are also added to the polymerizable components. In order to obtain the resin according to the present invention, a distillate prepared by distilling a fraction having a boiling point within the range of 145 to 220°C from a cracked oil fraction obtained by thermal decomposition of petroleum so as to satisfy the following conditions must be used. One of the requirements is to use fractions as feedstock. Conditions of feedstock oil (Hereinafter, among the cracked oil fractions obtained by thermal decomposition of petroleum, the fraction with a boiling point within the range of 145 to 220°C will be referred to as "starting feedstock oil", and the fraction obtained by distilling this A distillate that satisfies the following conditions is called "raw oil (a)"
It is called. ). (a) The total content of cyclopentadiene and methylcyclopentadiene in feedstock oil (a), that is, the conjugated diolefin content, is 0.7 wt% or less, and the conjugated diolefin content defined by formula (1) is 3.

(b) The total content of indene and its alkyl derivatives in the raw oil (a) is 2 wt% or less, and the indene content defined by formula (2) is 8% or less.

Analyze with. (ii) Each component other than those shown in (i) was analyzed using a 3 m long column filled with Celite containing 20 wt% polyethylene glycol 4000 at 125°C and a helium flow rate of 60 c.c./min. do. The total content of styrene and its alkyl derivatives, vinyltoluenes, indene and its alkyl derivatives, and cyclopentadiene and methylcyclopentadiene analyzed by the above method is defined as a polymerizable component. In order to distill the starting stock oil to obtain the stock oil (a), the starting stock oil is usually distilled using 15 to 50 theoretical plates.
It is preferably packed in a distillation column with 20 to 40 plates, and distilled under normal pressure, preferably reduced pressure, to obtain an oil distilled from the top of the column or a side stream distillate above the center of the column. Preferably, the above-mentioned top distillate oil is further charged into another vacuum distillation column (usually having 5 to 30 theoretical plates), the top distillate oil is separated and removed, and the bottom oil is recovered. . The raw material oil (a) thus obtained needs to have the properties described above, but usually the styrene content in this raw material oil (a) is 5 wt% or less,
Furthermore, it is less than 2wt%. In the method for producing resin according to the present invention, raw material oil (a)
The conjugated diolefin content, which is the regulatory limit for
0.7wt%, conjugated diolefin content 3%, indene and its alkyl derivatives content 2wt% and indene content 8%, vinyltoluene content 60-90%, preferably 70%-85%.
Even if the polymerization is carried out under the above polymerization conditions using raw materials that exceed the regulatory limits for even one of the items, the color and heat stability of the resulting resin will be poor, and the coloration will be particularly marked, and furthermore, when used as a hot-melt adhesive. The adhesion, flexibility, and heat resistance stability of the adhesive deteriorates, resulting in insufficient performance as an adhesive. In the present invention, the component (b) is added to the raw material oil (a).
One or more of these are added as essential ingredients. The purity of the component (b) does not need to be 100%,
Cyclopentadiene, dicyclopentadiene, etc.
It is also possible to use fractions containing up to about 40%. If component (b) is not added, or if the amount added is less than 5 parts by weight per 100 parts by weight of raw material oil (a), the compatibility with the ethylene copolymer will be poor and the clouding point of the blend will decrease. The adhesive properties of the hot melt composition are also high, making it impossible to obtain a hot melt composition with excellent adhesive properties. Further, even if more than 50 parts by weight of the above components are added to 100 parts by weight of the raw material oil (a), a hot-melt adhesive with excellent adhesiveness cannot be obtained. Therefore, the above components are used in an amount of 5 to 50 parts by weight, preferably 5 to 40 parts by weight, based on 100 parts by weight of the raw material oil (a). Furthermore, in the case of polymerizing as a raw material oil in which 5 to 50 parts by weight of at least one selected from the above component (b) is added to 100 parts by weight of the above raw material oil (a), ethylene copolymers, waxes, etc. In order to obtain a resin that has good compatibility with the resin and has excellent adhesive properties, it is necessary to coexist with a suitable compound. In the present invention, phenolic -OH is present in the molecule of phenol or alkyl-substituted phenols such as cresol, xylenol, p-t-butylphenol, p-octylphenol, and nonyl-phenol.
The polymerization is carried out in the presence of 0.1 to 3.0 parts by weight, preferably 0.5 to 2 parts by weight, of a phenol having a group, usually having 6 to 20 carbon atoms, based on 100 parts by weight of the raw oil (a). The method for producing a tackifying resin using these polymerization raw materials is as follows. That is, these polymerization raw materials are placed in a polymerization reactor and the reaction temperature is usually -30 to 80°C, preferably 0 to 60°C.
Polymerization is carried out at °C using a Friedel-Crafts type catalyst as the catalyst. The polymerization reaction can be carried out continuously or batchwise. After the polymerization reaction, the catalyst is deactivated with alkali, water, alcohol, etc., the catalyst is removed, and the unreacted oil fraction and low-molecular polymers are removed by evaporation or distillation to achieve a softening point of 60 to 120.
An aromatic resin having a temperature of 80 to 100°C is obtained. As the Friedel-Crafts type catalyst, boron trifluoride, aluminum chloride, etc. are typically used, and various complexes thereof, such as ether and phenol complexes, are used. These catalysts are usually 0.01~
Use 5wt%, preferably 0.1-3wt%. In the present invention, the polymerization is carried out in the presence of phenols as described above, but the phenols can also be supplied as a phenol complex of a Friedel-Crafts type catalyst. Although it is not advantageous to supply all the necessary amount of phenols as a phenol complex because the amount of catalyst is too large, it is possible to supply a part of the phenols as a phenol complex and add the other part as is to the polymerization system. This is preferably adopted. Note that a resin obtained by hydrogenating some or all of the unsaturated double bonds in the aromatic resin thus obtained can also be effectively used as a tackifying resin component. The hot melt composition of the present invention is prepared by heating and melt-mixing the above-mentioned resin as a tackifying resin component and an ethylene copolymer and waxes as required. The blending ratio can be appropriately selected from the following wide range. Usually, their compounding ratio is 20 to 300 parts by weight, preferably 30 to 200 parts by weight of the above-mentioned tackifying resin, and 0 to 500 parts by weight, preferably 10 to 400 parts by weight of the waxes, per 100 parts by weight of the ethylene copolymer. It is indicated by. Further, if necessary, 0 to 5 parts by weight of fillers such as calcium carbonate, titanium oxide, talc, and clay, 0 to 5 parts by weight of antioxidants, 0 to 20 parts by weight of plasticizers, pigments, etc. can be blended. . When using the above formulation as an adhesive for paper, plastic film, aluminum foil, and other packaging materials, choose a formulation with relatively low ethylene copolymer content, and require relatively strong adhesive strength for woodworking, bookbinding, etc. In some cases, it is desirable to prepare a hot melt composition by blending a large amount of the ethylene copolymer. Examples will be shown below to clarify the content of the present invention more specifically. Example 1 First, the tackifying resin component used in the present invention is manufactured, for example, as follows. As an example, cracked oil fraction F with a boiling point range of 145° C. to 220° C., which is produced as a by-product in the steam cracking of naphtha, showed the following composition based on the results of gas chromatography analysis. Polymerizable components (wt%) 47.63 Total content of cyclopentadiene and methylcyclopentadiene (wt%) 1.9 Total content of indene and its alkyl derivatives (wt%) 10.2 Dicyclopentadiene content (wt%) 0.7 Conjugated diolefin content Rate (%) 4.0 Indene content rate (%) 21.4 Using this cracked oil fraction F as the starting material oil, Table 2
The rectification column A-1 shown in Figure 1 is charged via a heater, and from the top of the column, the total content of indene and its alkyl derivatives is 2 wt% or less, which is one of the regulatory conditions for the feedstock of the present invention, and the indene content is The operating conditions of the rectifying column are set so that a fraction with a concentration of 8% or less can be obtained. The conditions are shown in Table 2.

ÃïŒæãã[Table] From Table 3, the hot melt composition according to the present invention is
It is clear that not only adhesive properties but also low-temperature properties and color are excellent. This is clear from the fact that the resin according to the present invention has good compatibility with the ethylene copolymer, which is the base polymer of the hot melt composition, and from the low cloud point of the formulation as shown in Table 3. It is. In addition, the softening point of the resin used in the present invention depends on the application.
It can be selected from a wide range of 50 to 125°C, but if the softening point is below this range, the softening point of the hot melt composition will decrease and the heat resistance will deteriorate, and if it is too high, it will cause a decrease in compatibility. Since adhesiveness also decreases, a temperature range of 60°C to 120°C is preferred. Furthermore, it is used in the hot melt composition of the present invention.
If the copolymerization component content of ethylene-based copolymers such as EVA is too low, the compatibility will decrease,
The content of copolymer components should be 10
~60 wt%, preferably 15-45 wt% is suitable. In addition, as a wax component, it is usually 50â~93.3â
Natural waxes such as petroleum waxes with a melting point of (110ã~200ã) and carnauba wax can be used, but low molecular weight waxes produced as by-products during polyethylene production and various synthetic waxes are especially softened. A hot melt composition with a high score and excellent adhesive properties can be obtained. Test method (1) Softening point (ring method) According to JIS K-2531. (2) Melt viscosity Measured using a Bruckfield viscometer. (3) Adhesive strength Base material: Aluminum Press at 180â for 3 minutes so that the adhesive layer is 0.2mm between 0.1mm aluminum plates, 20±1â, humidity 60%
