The present invention relates to a vinyl chloride resin composition that is stable against outdoor exposure. If a colored molded product made of vinyl chloride resin is used under direct sunlight, the surface of the exposed part will become white, as if it had been wiped with powder, and the original color tone of the molded product will change drastically, resulting in the molded product being damaged. It is well known that the appearance is significantly impaired. This phenomenon of whitish coloration occurs when exposed outdoors, but it is a unique phenomenon that cannot be reproduced with a weatherometer, which is commonly used as a weather resistance acceleration tester for synthetic resin molded products, and is called yoking. Rain gutters, decking materials, etc. are used outdoors for long periods of time, so when using vinyl chloride resin molded products for such purposes, various conventional methods have been used to suppress the occurrence of chocking and delay its occurrence. Stabilizers have been added to vinyl chloride resins. Among them, organotin compounds, cadmium metal soaps, and lead metal soaps are widely used because of their excellent anti-choke effect, but even if vinyl chloride resin compositions containing these stabilizers are used, their molded products cannot be processed. Chiyoking begins to occur after 2 to 10 months when exposed outdoors. In this way, even if the stabilizer has an excellent anti-yoking effect,
It could not be said to be sufficient for applications involving long-term outdoor exposure. Therefore, there has been a strong demand for a stabilizer that has a long-lasting inhibitory effect on yoking, and has been extensively researched, but no satisfactory stabilizer has yet been found. In view of this situation, the present inventors conducted extensive research and found that manganese chloride has a choking inhibiting effect, and that this effect lasts for a significantly longer period of time than that of organic tin-based compounds that have been widely used in the past. This led to the present invention. That is, the present invention relates to a vinyl chloride resin composition characterized by containing manganese chloride. The composition of the present invention can be formed by adding and mixing manganese chloride to vinyl chloride resin, but regarding the proportion of cobalt resin acid used,
Usually 0.05 to 5 per 100 parts by weight (shown below)
parts, preferably 0.5 to 2 parts, are suitable. The vinyl chloride resin referred to herein refers to a homopolymer or copolymer containing vinyl chloride as a constituent monomer. These polymers may contain colorant components, plasticizers, heat stabilizers, modifiers, lubricants, and other known performance-enhancing components. When adding and mixing manganese chloride to vinyl chloride resin, care must be taken to achieve uniform dispersion, and for this purpose it is necessary to use it in the form of a fine powder and to thoroughly knead it. The mixing method is to add directly to the vinyl chloride resin and mix, or to mix it with the vinyl chloride resin, such as a coloring agent component, a plasticizer, a heat stabilizer, a modifier, a lubricant, etc. with well-known performance. There is a method in which the improving component is included in advance and mixed into the vinyl chloride resin, but the latter method is preferred because it is easier to uniformly disperse. In particular, when using a colorant component, sufficient consideration must be given to the preparation so that the colorant component can be uniformly and easily dispersed in the vinyl chloride resin, so it is recommended that manganese chloride be present in the dye and pigment when preparing the colorant. , are suitable because their uniform dispersibility is particularly excellent. The form of the colorant component is a fine powder dry color, a wet type color produced by a grinding process, a pellet or plate masterbatch solidified with resin or other excipients, a plasticizer or other liquid or Good results can be obtained with any paste color using a low-temperature softening point compound as a vehicle. The thus obtained composition of the present invention is stable against outdoor exposure, and even when used for equipment and tools used outdoors, the occurrence of choking is significantly suppressed for a long period of time, so it is suitable for use in rain gutters, rain gutters, etc. Ideal for use as decking material, etc. The present invention will be explained below with reference to Examples. Note that the choke suppression coefficient in the examples was calculated from the following formula. △E C - △E I / △E C ×100 △E I = Color difference after outdoor exposure of a sheet of the composition of the present invention containing a yoking inhibitor △E C = Same as above except that it does not contain a yoking inhibitor Color difference after a sheet of a composition comparison composition is exposed outdoors for the same period and under the same conditions as above. Therefore, the closer the value of this coefficient is to 100 for a certain outdoor exposure period, the better the yoking suppression effect is. . Example 1 Vinyl chloride resin (Sumitomo Chemical, Sumiritz)
SX11F, degree of polymerization 1100) 100 parts of Ca-Zn stabilizer (Interstub M62D manufactured by Nippon Interstub)
Three parts were added and mixed to obtain a compound. 103 parts of the compound, 0.7 parts of Bengara, and titanium dioxide.
Add and mix 0.5 part and 1 part of manganese chloride, and heat to 155℃.
After kneading for 5 minutes using two 6-inch rolls, a sheet with a thickness of 1 mm was prepared using a hot press and exposed outdoors. Comparative Example 1 A sheet was prepared in exactly the same manner as in Example 1 except that the same amount of dibutyltin dilaurate was used instead of manganese chloride, and exposed outdoors. Table 1 shows the yoking inhibition coefficients after 16 months, 20 months, and 24 months of exposure in each of the above cases.
