The present invention relates to a polyvinyl chloride resin composition, and more particularly to a polyvinyl chloride resin composition whose stability has been improved by adding a lead stabilizer and a metal perchlorate. When polyvinyl chloride resin is subjected to thermoforming, it tends to undergo thermal decomposition mainly due to dehydrochlorination, which causes a decrease in the mechanical properties and color tone of the processed product, resulting in significant disadvantages. cause
In order to avoid such disadvantages, it is necessary to add one or more kinds of heat stabilizers to the synthetic resin to suppress deterioration during processing steps. For example, lead-based stabilizers have a stabilizing effect on vinyl chloride resin against thermal deterioration and are widely used. However, vinyl chloride resins to which lead-based stabilizers are added have drawbacks such as initial coloring during processing and insufficient light stability of the product. In particular, when vinyl chloride resin products are used outdoors, a whitening phenomenon called yoking occurs, causing the surface of the product to lose its luster, which significantly impairs the value of the product, posing a problem. Furthermore, in recent years, even higher thermal stability under severe temperature conditions has been required. As a result of studies to improve the above-mentioned drawbacks, the inventors of the present invention found that the use of metal perchlorate in combination with a lead-based stabilizer can prevent initial coloring and provide excellent thermal stability and photostability. Ta. That is, the present invention provides a stabilized polyvinyl chloride resin prepared by adding 0.1 to 10 parts by weight of a lead-based stabilizer and 0.001 to 3 parts by weight of a metal perchlorate to 100 parts by weight of a polyvinyl chloride resin. A composition is provided. The composition of the present invention will be explained in detail below. Examples of lead-based stabilizers used in the present invention include white lead, basic lead silicate, basic lead sulfate, dibasic lead sulfate, tribasic lead sulfate, basic lead sulfite, and dibasic phosphorus. Acid lead, silica gel co-precipitated lead silicate, dibasic lead phthalate, tribasic lead maleate, lead salicylate, lead stearate, dibasic lead stearate, lead laurate, lead octylate, 12-hydroxystearin Examples include lead acid and lead behenate. The amount of the lead-based stabilizer added is 0.1 to 10 parts by weight, preferably 0.5 to 5 parts by weight, per 100 parts by weight of the resin. In addition, perchloric acid metal salts used in the present invention include perchloric acid Zn, Al, Cd, K, Ca, Sr,
Mention may be made of Na, Ba, Mg and Li salts. Naturally, these may be hydrated salts. The amount of the metal perchlorate added is 0.001 to 3 parts by weight, preferably 0.01 to 0.5 parts by weight per 100 parts by weight of the resin.
Parts by weight. Examples of the polyvinyl chloride resin stabilized by the present invention include polyvinyl chloride and copolymers mainly composed of vinyl chloride, such as vinyl chloride-vinyl acetate copolymers, vinyl chloride-ethylene copolymers, Vinyl chloride-propylene copolymer, vinyl chloride-styrene copolymer, vinyl chloride-isobutylene copolymer, vinyl chloride-vinylidene chloride copolymer, vinyl chloride-styrene-maleic anhydride terpolymer, vinyl chloride- Styrene-acrylonitrile copolymer, vinyl chloride-butadiene copolymer, vinyl chloride-isoprene copolymer, vinyl chloride-chlorinated propylene copolymer, vinyl chloride-vinylidene chloride-vinyl acetate terpolymer, vinyl chloride- Acrylic ester copolymer, vinyl chloride-maleic ester copolymer, vinyl chloride-methacrylic ester copolymer, vinyl chloride-acrylonitrile copolymer, and these resins and polyethylene, polypropylene, polybutene, poly-3- α-olefin polymers such as methylbutene or polyolefins such as ethylene-vinyl acetate copolymers, ethylene-propylene copolymers and their copolymers, polystyrene, acrylic resins, styrene and other monomers (e.g. maleic anhydride, butadiene, acrylonitrile, etc.), acrylonitrile-butadiene-styrene copolymers, acrylic ester-butadiene-styrene copolymers, and methacrylic ester-butadiene-styrene copolymers. can. In addition to the stabilizer system of the present invention, known stabilizers such as metal soaps, organotin compounds, polyhydric alcohols,
A β-diketone compound, an epoxy compound, an aminocrotonic acid ester, a phosphite antioxidant, a phenolic antioxidant, an ultraviolet absorber, and a hindered amine light stabilizer can be added.

The following examples show the effects of the vinyl chloride resin composition according to the present invention, but the present invention is not limited to these examples. Example 1 The following composition was kneaded with a roll and then pressed to produce a sheet with a thickness of 0.5 mm. Using this sheet, initial colorability and thermal stability at 190°C were measured. In addition, the degree of yoking during outdoor exposure was measured. The results are shown in Table 1.
