DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a novel vinyl chloride resin composition. Specifically, it is a vinyl chloride resin composition that is extremely stable against the effects of ultraviolet rays and infrared rays, and furthermore, is degraded due to oxygen and moisture in the air.
An object of the present invention is to provide a vinyl chloride resin composition capable of preventing occurrence of choking of a processed product used outdoors for a long period of time.

[0002]

2. Description of the Related Art Vinyl chloride resins are water-resistant, acid-resistant,
Although it has excellent properties of being excellent in alkali resistance and being hardly soluble in an organic solvent, it has a drawback of being unstable to heat and light. In particular, vinyl chloride resin used for processed products such as pipes, rain gutters and window frames used for a long time outdoors is exposed to sunlight,
A whitening phenomenon called choking occurs on the surface,
The appearance is impaired.

Conventionally, in order to prevent the above-mentioned choking,
A vinyl chloride resin composition in which nickel acetate, manganese chloride, copper oxide, or the like is added to a vinyl chloride resin has been proposed (JP-A-56-22342). Further, a vinyl chloride resin composition having improved anti-chalking properties by adding copper carboxylate to the vinyl chloride resin has been proposed (Japanese Patent Application Laid-Open No. 59-102943).

[0004] However, these resin compositions are used in chocolates.
Although a certain degree of prevention effect on the occurrence of king is exhibited, it is still insufficient.

As a technique for further improving the choking prevention performance, a vinyl chloride resin composition in which copper acetate and hydrotalcite are added to a vinyl chloride resin has been proposed (JP-A-6-322206). However, there is still room for improvement in the anti-chalking performance of the above-mentioned vinyl chloride resin composition, and development of a vinyl chloride resin composition having a higher anti-chalking effect has been desired.

As a technique for improving the durability (weather resistance) performance of a vinyl chloride resin film, a stabilizer contained in a vinyl chloride resin composition is composed of zinc pt-butyl benzoate and a barium salt of a higher fatty acid. There has been proposed a vinyl chloride resin film as a stabilizer containing
-44751). However, even with the above stabilizer, there is still room for improvement in the anti-chalking performance.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a vinyl chloride resin composition which can exhibit extremely high choking prevention performance.

[0008]

Means for Solving the Problems As a result of repeated studies to solve the above-mentioned problems, the present inventors have found that by using an organic copper carboxylate and an aluminum alkylbenzoate together with a vinyl chloride resin, The present inventors have found that an extremely high anti-chalking performance, which could not be achieved by a conventional composition using organic copper carboxylate or a combination thereof with hydrotalcite, can be achieved, and have completed the present invention.

That is, the present invention is a vinyl chloride resin composition comprising copper organic carboxylate and aluminum alkyl benzoate.

[0010] The vinyl chloride resin composition of the present invention, in which such two-component additives are used in combination, can dramatically improve the choking prevention performance when blended with a vinyl chloride resin as compared with the prior art. It is.
