Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl chloride resin composition for glass / vinyl chloride resin integral molding used in vehicles, buildings and the like, and a glass / vinyl chloride resin integral molding using the same.

[0002]

2. Description of the Related Art Generally, rubber, vinyl chloride resin or the like is used as a frame material (hereinafter referred to as a molding) used for window materials such as rear windows and quarter windows for automobiles.

Conventionally, these window members have been mounted on the vehicle body by a method in which a glass is fitted into a frame body of a vehicle body through a sealing material and then a molding is attached thereto. It was not economical due to the large number of processes.

In order to solve the above problems, various methods have been proposed. For example, in JP-A-62-68992 and JP-A-2-60722, a glass / vinyl chloride resin integral molding method is proposed. (Hereinafter, referred to as a module window method), that is, glass is set in a mold of an injection molding machine, a frame material made of vinyl chloride resin is integrally molded on the peripheral edge of the glass, and the obtained window material is used as a vehicle body. A method of mounting is proposed.

As the vinyl chloride resin used in the above module window system, a composition obtained by adding a plasticizer to a vinyl chloride homopolymer is used. However,
Since this composition has poor fluidity during injection molding, it is necessary to increase injection pressure, mold clamping pressure, etc. in order to completely cover the glass peripheral edge with an injection molded product of vinyl chloride resin. However, there was a drawback that the glass was apt to be damaged due to being tightened with a strong pressure.

On the other hand, as a method for improving the fluidity of the vinyl chloride resin at the time of injection molding, it has been attempted to lower the polymerization degree of the vinyl chloride resin. However, the plasticizer bleeding out from the inside of the obtained injection-molded product results in a decrease in the mechanical properties of the injection-molded product or the surface of the injection-molded product is deteriorated. It had the drawback of being tacky.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and is a vinyl chloride resin composition and a machine for glass / vinyl chloride resin integral molding excellent in fluidity during injection molding. It is an object of the present invention to provide a glass / vinyl chloride resin integrated molding having excellent physical properties and having no tackiness on the surface.

It is characterized by comprising 5 to 40 parts by weight of an ethylene-vinyl acetate copolymer having a content of 0 to 250 (gr / 10 minutes).

The glass / vinyl chloride resin integrally molded article of the invention 4 is characterized in that the above vinyl chloride resin composition is integrally formed on the peripheral portion of the glass by injection molding. There is.

The vinyl chloride resin used in the present invention includes, in addition to vinyl chloride homopolymer, the fluidity of the vinyl chloride resin composition at the time of injection molding and the mechanical properties of the finally obtained molded product. Etc. within the range that does not decrease, a copolymer of vinyl chloride and a polymerizable monomer copolymerizable with vinyl chloride, or a grafted vinyl chloride grafted onto a polymerizable resin copolymerizable with vinyl chloride. Examples thereof include copolymers. The content of the structural unit formed of the above polymerizable monomer or polymerizable resin in the copolymer is 40% by weight.
It is preferable not to exceed.

The polymerizable monomer is not particularly limited as long as it has a reactive double bond, and examples thereof include α-olefins such as ethylene, propylene and butylene, vinyl acetate and propionic acid. Vinyl esters such as vinyl, vinyl ethers such as butyl vinyl ether and cetyl vinyl ether, acrylic acid esters such as methyl acrylate and ethyl acrylate, methacrylic acid esters such as methyl methacrylate, ethyl methacrylate and phenyl methacrylate, styrene, α-methylstyrene And the like, vinylidene chloride, vinyl halides such as vinyl fluoride, and N-substituted maleimides such as N-phenylmaleimide and N-cyclohexylmaleimide. These may be used alone or in combination of two or more.

The above-mentioned polymerizable resin is not particularly limited, and examples thereof include ethylene-vinyl acetate copolymer, ethylene-vinyl acetate-carbon monoxide copolymer,
Ethylene-ethyl acrylate copolymer, ethylene-ethyl acrylate-carbon monoxide copolymer, ethylene-methyl methacrylate copolymer, ethylene-propylene copolymer, acrylonitrile-butadiene copolymer, polyurethane resin, chlorinated polyethylene resin , Chlorinated polypropylene resin and the like. These may be used alone or in combination of two or more.

If the average degree of polymerization of this vinyl chloride resin becomes small, the mechanical properties of the molded product finally obtained will deteriorate, and the holding power of the plasticizer will also decrease and the surface of the molded product will have tackiness. If it becomes large, the fluidity of the vinyl chloride resin composition at the time of injection molding decreases, so 400 to 150
0 is preferred.

Any method may be adopted as the method for producing the vinyl chloride resin, for example, a well-known suspension polymerization method or emulsion weight method which is usually used in the polymerization of vinyl chloride using a radical polymerization initiator. Examples include a legal method, a solution polymerization method, and a bulk polymerization method. The suspension polymerization method is preferably used because impurities are unlikely to be contained in the obtained polymer and the production cost is relatively low.

The plasticizer used in the present invention is not particularly limited as long as it is compatible with the vinyl chloride resin, and examples thereof include diethyl phthalate and di-n-octyl phthalate. Phthalates such as diisodecyl phthalate, dibutyl adipate, adipic acid such as di-n-hexyl adipate, tributyl phosphate, phosphates such as tri-2-ethylhexyl phosphate, tributyl trimellitate, trimellitate Examples include trimellitic acid-based acid such as tri-2-ethylhexyl acid, chlorinated paraffin-based, polyester-based, etc., but especially diisodecyl phthalate (hereinafter, referred to as DI with low volatility and excellent fogging resistance).

When the amount of such a plasticizer added is small, the fluidity at the time of injection molding decreases, and when it is large, tackiness appears on the surface of the finally obtained molded product, so 100 parts by weight of the above vinyl chloride resin is used. 20 to 150 parts by weight.

The terpene resin represented by the above formula (1) used in the present invention 1 has a number average molecular weight of 400 to 10
When the number average molecular weight is less than 400, the hydrogenated terpene resin becomes extremely brittle, and the molded product made of the vinyl chloride resin composition to which it is added has a lower mechanical strength. On the contrary, the viscosity of the hydrogenated terpene resin of more than 1000 becomes high, so that the vinyl chloride resin composition to which the hydrogenated terpene resin is added has poor fluidity at the time of heat melting and deteriorates moldability. In addition, this number average molecular weight means the calculated value from the measured value by the GPC method.

This hydrogenated terpene resin can be used alone or in combination of two or more kinds, and the addition amount thereof is 1 to 10 with respect to 100 parts by weight of vinyl chloride resin as described above. When the amount is less than 1 part by weight, the fluidity of the vinyl chloride resin composition at the time of injection molding is insufficient, and when it exceeds 10 parts by weight, the mechanical properties of the obtained molded article deteriorate.

The average particle diameter of the glass hollow spheres is 50 to 2
If the average particle size is less than 50 μm, or if it exceeds 200 μm, the flow of the vinyl chloride resin composition containing glass hollow spheres having such a particle size at the time of heat melting is defined as 00 μm. This is because the sex is not improved.

The glass hollow spheres may be used alone or in combination of two or more, and the addition amount thereof is 1 to 20 per 100 parts by weight of the vinyl chloride resin as described above. When the amount is less than 1 part by weight, the fluidity at the time of injection molding is reduced, and when it exceeds 20 parts by weight, the mechanical properties of the finally obtained molded article are deteriorated and at the time of injection molding. This is because the liquidity of is also reduced.

As described above, the ethylene-vinyl acetate copolymer used in the invention 3 has a vinyl acetate content of 50 to 80% by weight when it is less than 50% by weight with a vinyl chloride resin. When the compatibility is lowered, the mechanical properties are lowered, and when it exceeds 80% by weight, the compatibility with the vinyl chloride resin is improved but the fluidity is lowered and the flexibility and weather resistance of the obtained molded article are lowered. From
