Abstract

The invention relates to the technical field of chemical stabilizers, in particular to a transparent environment-friendly calcium zinc stabilizer and a preparation method thereof. The transparent environment-friendly calcium zinc stabilizer is prepared from the following raw materials in percentage by mass: 10 to 30 percent of calcium salt main stabilizer, 10 to 30 percent of zinc salt main stabilizer, 30 to 50 percent of hydrotalcite, 10 to 20 percent of lubricant, 1 to 5 percent of antioxidant, 1 to 5 percent of ultraviolet absorber and 1 to 5 percent of auxiliary stabilizer. The preparation method for the transparent environment-friendly calcium zinc stabilizer comprises the following steps of: adding the raw materials into a high speed stirrer in three stages, jointly stirring at the temperature of between 55 and 56DEG C for 30 minutes, and making the rotating speed of the stirrer 1,000-1,500r / min. The prepared transparent environment-friendly calcium zinc stabilizer has high heatresistance, high transparency and copper rust resistance.

Description

technical field [0001] The invention relates to the technical field of chemical stabilizers, in particular to a transparent and environment-friendly calcium-zinc 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. 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 comple...
