Calcium-zinc compound stabilizer as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of chemical stabilizers and discloses a calcium-zinc compound stabilizer as well as a preparation method and application thereof. The calcium-zinc compoundstabilizer is prepared from the following raw materials in percentage by mass: 10 to 30 percent of 2-ethylcaproic acid, 2 to 10 percent of benzoic acid, 0.5 to 4.2 percent of zinc oxide, 1.2 to 6.5 percent of calcium oxide, 8 to 15 percent of non-toxic phosphite, 20 to 35 percent of DINCH, 1 to 5 percent of ATBC, 0.1 to 3 percent of TXIB and 8 to 32 percent of chloromethyl ester. The novel calcium-zinc compound stabilizer disclosed by the invention, under the specific calcium-zinc salt ratio, creatively uses a novel non-toxic environment-friendly compound plastifier to obtain a colorless transparent liquid calcium-zinc stabilizer; and in addition, the method disclosed by the invention is simple in production technology and is easy to realize.

Description

technical field

[0001] The invention belongs to the technical field of chemical stabilizers, and more specifically relates to a calcium-zinc composite stabilizer and its preparation method and application. Background technique

[0002] Known heat stabilizers in the PVC industry mainly include lead salts, metal soaps, organotin, rare earth and Ca / Zn stabilizers, but the most widely used heat stabilizers are lead salts and metal soaps. Lead salt stabilizers are cheap and have good thermal stability effects, but they are highly toxic, seriously endangering human health and polluting the environment, and lead salt stabilizers have the disadvantage of being opaque. Organotin stabilizers not only have good transparency and thermal stability, but also have low toxicity. They are widely used in high-transparency polyvinyl chloride sheets, sheets, food, and pharmaceutical packaging, but they are expensive, and some products are more toxic in terms of toxicity. The control is complet...
