【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to vinyl chloride resin compositions that are stable against outdoor exposure. Vinyl chloride resin is a general-purpose thermoplastic resin, but it is unstable to heat and light, causing discoloration during hot molding, reduced mechanical strength, and poor weather resistance when molded products are used outdoors. There is a big drawback. Especially rain gutters that are used outdoors for a long time,
The surfaces of pipes, window frames, decking materials, etc. that are exposed to sunlight undergo a whitening phenomenon called yoking, which significantly impairs their appearance. To improve these shortcomings, metal soaps, lead-based compounds, organic tin-based compounds, ultraviolet absorbers, ultraviolet stabilizers, lubricants, fillers, colorants, etc. are selectively added to vinyl chloride resin to produce molded products. However, a vinyl chloride resin composition that is stable against yoking has not yet been obtained. In view of this situation, the inventors of the present invention have conducted intensive studies and have discovered that copper acetate has an effect of preventing choking, leading to the present invention. That is, the present invention relates to a vinyl chloride resin composition containing 0.001 to 0.5 parts by weight of copper acetate per 100 parts by weight of the vinyl chloride resin. In the present invention, vinyl chloride resin refers to a homopolymer or copolymer containing vinyl chloride as a constituent monomer, and these polymers include metal soaps, lead-based compounds,
Organotin compounds, ultraviolet absorbers, ultraviolet stabilizers,
There is no problem even if lubricants, fillers, colorants, and plasticizers coexist. The amount of copper acetate used is 0.001 to 0.5 parts by weight, preferably 0.01 to 0.2 parts by weight, per 100 parts by weight of vinyl chloride resin.
A range of parts by weight is appropriate. If the amount used is less than 0.001 parts by weight, the anti-yoking effect will not be sufficient.
If it exceeds 0.5 part by weight, the anti-yoking effect will be reduced and the heat resistance stability of the vinyl chloride resin may be reduced. As for the method of adding copper acetate to the vinyl chloride resin, it may be added directly to the vinyl chloride resin and mixed, or it may be included in a colorant component and then mixed with the vinyl chloride resin. The present invention will be explained below with reference to Examples. <Example 1> 100 parts by weight of vinyl chloride resin (degree of polymerization 1100),
0.3 parts by weight of calcium stearate, 0.7 parts by weight of zinc stearate, 0.1 parts by weight of dibutyltin malate, 1 part by weight of Bengara, 0.5 parts by weight of polyethylene wax, and 0.1 parts by weight of copper acetate were mixed in a high-speed mixer for 3 minutes, and heated to 160°C. After kneading for 5 minutes using two inch rolls, a 1 mm thick sheet was prepared using a heat press and exposed outdoors. <Comparative Examples 1 and 2> Sheets were prepared in exactly the same manner as in Example 1 except that the amount of copper acetate used was outside the range of the present invention, and exposed outdoors. After 12 months and 18 months of exposure in each of the above cases,
After 24 months, the degree of discoloration including yoking was measured using a color difference meter (SS Color Computer Model SS-1, manufactured by Suga Test Instruments) using a sheet that has not been exposed outdoors as a standard, and the color difference is shown in Table 1 as △E value. indicate. The smaller the ΔE value, the greater the choke-preventing effect. 【table】
