Abstract

The present invention relates to a kind of PVC plastic composition that uses maleopimarate as heat stabilizer, namely use maleopimaric acid (MPA hereinafter the same) and ZnO, MgO etc. to carry out salt-forming reaction to obtain maleopimarate and its compound molecule The structural formula is shown in the figure below. Use this product as a PVC heat stabilizer and combine it with other plastic processing aids to form a formula to obtain a processing aid for PVC plastic products. The dynamic fusion rheological properties and static thermal stability of this additive in PVC materials meet the requirements for use. , prove that the maleopimaric acid salt that the present invention obtains provides a good environment-friendly heat stabilizer for the processing of PVC plastic product material. Wherein: M=Zn, Mg, Ca.

Description

1. Technical field [0001] The invention belongs to the field of formula modification of plastic raw materials, in particular to the field of formula modification of polyvinyl chloride plastic product processing aids. 2. Background technology [0002] Plastic heat stabilizers are mainly additives used in PVC plastic processing and production. They play an extremely important role in the processing of plastic products. The currently widely used cadmium lead heat stabilizer system has been banned due to its harm to the environment. Lead salt heat stabilizers will also be phased out during 2015-2020 (Shi Xunruo, Lou Xudong. Present situation and development of heat stabilizers for PVC processing [J]. Polyvinyl chloride, 2009, 37(2): 1- 5.). How to reduce the pollution and harm caused by lead-containing metal PVC products to the environment and related personnel in the process of production and recycling is an inevitable trend for my country's PVC plastic products to be in line ...
