Abstract

The invention discloses a stabilizer for PVC sheets and a preparation method thereof. The stabilizer for PVC sheets is prepared from the following raw materials by weight: 1-10 parts of a main stabilizer A, 10-15 parts of a main stabilizer B, 35-55 parts of an auxiliary stabilizer C, 1-10 parts of an auxiliary stabilizer D, 5-10 parts of an antioxidant, 3-15 parts of a lubricant, 1-15 parts of a chelating agent, and 1-5 parts of an impact resistant agent. Specifically, the main stabilizer A is at least one of calcium stearate, strontium stearate and calcium benzoate; the main stabilizer B is at least one of zinc stearate, lanthanum stearate and zinc benzoate; the auxiliary stabilizer C is at least one of magnesium-aluminum hydrotalcite and magnesium-aluminum-zinc hydrotalcite; and the auxiliary stabilizer D is at least one of dibenzoyl methane, stearoyl benzoyl methane and dodecyl dihydropyridine diformate. The stabilizer prepared according to the invention has the advantages of no toxicity, environmental protection, no odor, fast plasticization, high product transparency, good weather resistance and good ultraviolet aging resistance.

Description

technical field [0001] The invention belongs to the technical field of heat stabilizers, in particular to a stabilizer for PVC sheets and a preparation method thereof. Background technique [0002] The main components of PVC sheet include PVC resin, plasticizer and heat stabilizer. Heat stabilizer plays an important role in the manufacturing process of plastic products. [0003] There are many kinds of heat stabilizers for PVC plastic processing. The non-environmentally friendly ones include lead and cadmium soap heat stabilizers, and the environmentally friendly ones include calcium zinc-based heat stabilizers, methyl tin stabilizers and heterocyclic stabilizers. Although lead and cadmium soaps have good thermal stability, their inherent high toxicity has greatly limited their application range as the restrictions of environmental protection laws at home and abroad are approaching. In the field of PVC film materials, the use of methyl tin as the main stabilizer is already...
