Abstract

The invention relates to the technical field of a chemistry stabilizer, in particular to an environmental-friendly calcium-zinc stabilizer for a PVC (Polyvinyl Chloride) rolling film and a preparation method thereof. The environmental-friendly calcium-zinc stabilizer for the PVC (Polyvinyl Chloride) rolling film comprises the following raw materials in percentage by weight: 10-30% of main calcium salt stabilizer, 10-30% of main zinc salt stabilizer, 30-50% of hydrotalcite, 10-20% of lubricating agent, 5-15% of phenothiazine heterocyclic compound, 1-5% of oxidation inhibitor, 1-5% of ultraviolet light absorber and 1-5% of auxiliary stabilizer. The preparation method of the environmental-friendly calcium-zinc stabilizer for the PVC (Polyvinyl Chloride) rolling film comprises the following steps of: putting the raw materials in a high-speed blender in three stages and totally stirring for 30 min in the temperature of 55-56 DEG C, wherein the rotating speed of the blender is 1000-1500r / min. The environmental-friendly calcium-zinc stabilizer for the PVC (Polyvinyl Chloride) rolling film, which is prepared by the invention, has good thermal resistant property and weather resistance.

Description

technical field [0001] The invention relates to the technical field of chemical stabilizers, in particular to an environmentally friendly calcium-zinc stabilizer for PVC calendered films and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC), stabilizers, processing modifiers and inorganic materials are properly mixed to produce various PVC plastic products for different purposes. The main components in the preparation of PVC calendered film include polyvinyl chloride and stabilizer, and the performance of the stabilizer has a great influence on the stability of PVC calendered film. [0003] 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 ...
