Abstract

The invention relates to a high efficiency anti-precipitation liquid composite heat stabilizer and a preparation method thereof. The composite heat stabilizer is composed of the following raw materials by weight: 40-60 parts of barium carboxylate, 10-18 parts of mercapto zinc, 2-12 parts of an anti-settling agent, 10-35 parts of phosphate ester, 1-10 parts of an antioxidant, and 15-45 parts of a solvent. According to the invention, by adding of the anti-settling agent into the liquid composite heat stabilizer and solvent collocation of different carbon number distributions, the compatibility of all the components in the liquid composite stabilizer system is effectively improved, the storage stability is significantly improved, and the problem of short storage time in existing liquid composite stabilizers is solved. In addition, the mercapto zinc compound is added, the zinc salt contains a thiol structure and has good antioxidant effect, and the activity of mercapto zinc is greater thanthat of ordinary zinc carboxylate, can absorb allyl chloride more rapidly, and significantly improve the early whiteness of the product.

Description

technical field

[0001] The invention relates to a high-efficiency anti-separation liquid composite heat stabilizer and a preparation method thereof. Background technique

[0002] With the sustainable development of my country's economy and society, people's awareness of environmental protection and health is increasing. Non-toxic, non-polluting, composite and efficient composite heat stabilizers have become the development direction of PVC heat stabilizers worldwide. In particular, the liquid metal soap composite heat stabilizer, which has the advantages of no dust pollution, simple measurement, environmental protection, low price and simple process, has become the development direction of polymer material heat stabilizers in the future.

[0003] Liquid metal soap composite heat stabilizer is still in the research and development stage in my country, and the current research is not yet mature. The products on the market have disadvantages such as high cost, not environmental...
