Abstract

The invention discloses a lead salt stabilizer formula, which comprises 92-103 parts of polyvinyl chloride resin powder, 18-27 parts of nitrate trisalt, 9-15 parts of chlorinated disalt, and stearic acid in parts by weight. 1.5-2.5 parts of calcium, 1.5-2.5 parts of barium stearate, 1-2 parts of lead stearate, 0.5-1.5 parts of stearic acid, 6-9 parts of acrylic anti-impact agent, 6-13 parts of bentonite, stearin 2‑5 parts of citric acid, 2‑8 parts of active light calcium, 5‑11 parts of titanium dioxide, 0.5‑2 parts of oxidized polyethylene wax, and 0.5‑1 part of paraffin wax. The design of the mixing ratio of the present invention is extremely reasonable, and when it is attached to the surface of PVC during PVC resin processing, the adhesive force is excellent and no peeling will occur.

Description

technical field [0001] The invention relates to the field of preparation of lead salt stabilizers, in particular to a formulation of lead salt stabilizers. Background technique [0002] Lead salt stabilizer is a kind of heat stabilizer, heat stabilizer is one of the important categories of plastic processing aids, heat stabilizer and the birth and development of PVC resin are synchronized, mainly used in PVC resin processing, so heat stabilizer There is a close relationship between the agent and the proportion of soft and hard products in PVC resin and PVC. The mixing ratio of the existing lead salt stabilizer is unreasonably designed, and when it is attached to the surface of PVC during PVC resin processing, the adhesion is insufficient and it is easy to peel off. Contents of the invention [0003] The invention provides a lead salt stabilizer formula with extremely reasonable design of mixing ratio, excellent adhesion and no peeling off when it is attached to the surfac...
