Description

Calcium-zinc stabilizer with flame retardant effect
The technical field is as follows:
the invention relates to the field of plastic stabilizers, in particular to a calcium-zinc stabilizer with a flame retardant effect.
Background art:
since vinyl chloride resins are not only excellent in flame retardancy, chemical resistance, mechanical stability, transparency, adhesion, printability, etc., but also can be easily modified from hard to soft in hardness by adding a plasticizer, vinyl chloride resins are used in various applications. In particular, a hard vinyl chloride resin composition completely free of a plasticizer and a semi-hard vinyl chloride resin composition containing a small amount of a plasticizer have excellent rigidity, and thus are widely used for building materials and the like. Therefore, such vinyl chloride resin compositions are required to exhibit higher levels of properties not only during the treatment of exposure to high temperature and high pressure but also as molded articles in terms of thermal stability, resistance to coloration, resistance to thermal coloration, weather resistance, and the like. In addition, for hard transparent molded articles, vinyl chloride resins are also used as extremely general-purpose resins requiring glass-like transparency in containers, industrial sheets, decorative sheets, films, sheets and the like. On the other hand, vinyl chloride resins are known to have disadvantages in that they are not sufficiently stable to light and heat, and when they are heat molded or used as products, they may be degraded mainly by dehydrohalogenation.
In order to meet these performance requirements and overcome the disadvantages, it has been conventionally proposed to improve the stability of a vinyl chloride resin by adding various stabilizers such as organic acid metal salts, organic tin compounds, organic phosphite compounds and epoxy compounds, an antioxidant and an ultraviolet absorber.
However, even in vinyl chloride resin compositions containing such stabilizers, when they are thermally molded or used as products, degradation due to the reduction in molecular weight and dehydrohalogenation of the vinyl chloride resin thereof is not completely inhibited, resulting in poor stability. In addition, the flame retardant performance is to be further improved.
