Cobalt blue, bronze powder, etc. are pigments that have the risk of promoting the decomposition of vinyl chloride resin, and dark blue, zinc chromate, zinc powder, alumina white, zinc sulfide, etc., are the pigments that may reduce heat resistance. is there. For example, when a red iron oxide (Fe 2 O 3 ) is used as the pigment, the color of the red iron oxide fades by reacting with the vinyl chloride resin as follows due to sunlight or heat. Fe 2 O 3 + 6HCl → 2FeCl 3 + 3H 2 O However, by containing an ultraviolet absorber within the scope of the present invention, a large amount of ultraviolet energy is absorbed, so that the above reaction is suppressed. Further, by containing an antioxidant and hydrotalcite within the range of the present invention, the thermal stability of the vinyl chloride resin is improved and the above reaction is suppressed. Thus, by containing the ultraviolet absorber, the antioxidant and the hydrotalcite within the scope of the present invention, the weather resistance of the vinyl chloride resin is improved. However, it is disadvantageous in terms of cost and that the properties of the product are deteriorated if the content of these compounding agents is more than the upper limit value of the present invention. further,
In order to improve the processability, 10 parts by weight or more of the plasticizer is necessary, but if it exceeds 50 parts by weight, desired product characteristics cannot be obtained.
