Abstract

The invention discloses a PVC environment-friendly calcium-zinc composite stabilizer, which comprises the following components in parts by weight: 25-55 parts of an allantoin calcium-zinc compound, 20-35 parts of calcium lanolate, 5-15 parts of phosphite ester, 4-11 parts of polyol, 10-16 parts of a nitrogen-containing organic compound, 9-23 parts of magnesium-aluminum hydrotalcite, 5-13 parts ofbeta-diketone, 2-8 parts of an antioxidant, 5-18 parts of acrylamide and 5-8 parts of monoglyceride. Meanwhile, the invention also discloses a preparation method of the product. The PVC environment-friendly calcium-zinc composite stabilizer selects the allantoin calcium-zinc compound and the calcium lanolate as main stabilizers, is used for production of environment-friendly nontoxic stabilizers for PVC extrusion and injection molding processing industries, and is high in stability, good in comprehensive performance, nontoxic and environment-friendly..

Description

technical field [0001] The invention relates to the technical field of PVC stabilizers, in particular to a PVC environment-friendly calcium-zinc composite stabilizer and a preparation method thereof. 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. Lead stearate, tribasic lead sulfate, dibasic lead phosphite, etc. are traditional stabilizers commonly used in PVC extrusion and injection molding processing industries. They have excellent stability and low price, but lead is highly toxic and has The heavy metals of ecological pollution have caused great harm and threat t...
