Abstract

The invention discloses a formula of a barium-calcium composite stabilizer, calculated in parts by weight, comprising 25-30 parts of zinc stearate, 20-25 parts of calcium stearate, 15-20 parts of hydrotalcite and 15-20 parts of zeolite , 3-5 parts of polyethylene wax, 3-5 parts of paraffin wax, 15-20 parts of calcium carbonate, 1-5 parts of dibenzoylmethane, 4-11 parts of diquateritol, 2-7 parts of antioxidant, hydrogen chloride 1-4 parts of ammonium. The mixing ratio design of the invention is extremely reasonable, and when it is attached to the PVC surface during the processing of the PVC resin, the adhesion is excellent and no peeling occurs.

Description

technical field [0001] The invention relates to the field of barium-calcium composite stabilizer preparation, in particular to a formula of barium-calcium composite stabilizer. Background technique [0002] Barium-calcium composite stabilizer is one of heat stabilizers, heat stabilizers are one of the important categories of plastic processing aids, heat stabilizers are synchronized with the birth and development of PVC resin, and are mainly used in PVC resin processing, so heat stabilizers The stabilizer is closely related to the proportion of soft and hard products in PVC resin and PVC. The existing barium-calcium composite stabilizer has an unreasonable mix ratio design, and when it is attached to the PVC surface during PVC resin processing, the adhesive force is insufficient and it is easy to peel off. Contents of the invention [0003] The invention provides a formula of barium-calcium composite stabilizer with extremely reasonable design of mixing ratio, excellent a...
