Abstract
Disclosed is a rare-earth stabilizer for PVC (polyvinyl chloride). The rare-earth stabilizer comprises, by weight, 10-20 parts of zinc stearate, 6-25 parts of carboxylic acid rare-earth compounds, 8-16 parts of lubricants, 10-15 parts of auxiliary heat stabilizers, 6-18 parts of matrix resin, 7-14 parts of ultraviolet light absorption agents, 4-12 parts of C2-6 carboxylic acid zinc, 2-4 parts of diethlene glycol monobutyl ether, 6-12 parts of zinc oxide, 4-6 parts of polyhydric alcohols, 10-22 parts of barium oxide, 4-7 parts of beta-diketone, 10-14 parts of monocarboxylic acid and 4-8 parts of organic assistants. The rare-earth stabilizer has the advantages of good stabilization, weather fastness, light stability and easiness in process and low energy consumption.
Description
Technical field
The present invention relates to a kind of Rare earth composite heat stabilizer for PVC.
Background technology
Polyvinyl chloride has the features such as flame retardancy, wear resistance, resistance to chemical corrosion, comprehensive mechanical, electrical insulating property, obtains swift and violent development in recent years in China.Polyvinyl chloride is as one of five large general-purpose plastics, and its maximum shortcoming is that its thermostability in the course of processing is poor, and molding process must add a certain amount of thermo-stabilizer.Present polyvinyl chloride is commonly used thermo-stabilizer and is mainly contained lead salts, organic tin, metal soap and rare earth class etc.Lead salts thermo-stabilizer is poisonous and be cumulative poison, irritant smell in the organic tin thermo-stabilizer course of processing, expensive, poisonous in metal soap thermal stabilizers, persistence is poor.And the class New Heat Stabilizer that rare earth thermal stabilizer is development in recent years to get up, its excellent thermostability, good light stability, distinctive synergistic effect and consistency, and China's rare earth resources enriches, make full use of the rare earth resources advantage of China, so just greatly reduce cost, there is good economic benefit and social benefit.But the defects such as also there are some problems at present, when being used alone rare-earth stabilizer, thermostable effect is not bery desirable, tint permanence difference, require further improvement, improve performance.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of Rare earth composite heat stabilizer for PVC, and have excellent stability, weathering resistance, light stability, workability, energy consumption is low.
For solving prior art problem, technical scheme provided by the invention is, a kind of Rare earth composite heat stabilizer for PVC, and it is made up of the raw material of following parts by weight:
Zinic stearas 10-20 part, rare earth carboxylate compound 6-25 part, lubricant 8-16 part, auxiliary heat stabilizer 10-15 part, matrix resin 6-18 part, ultraviolet light absorption agent 7-14 part, C2-6 zinc carboxylate 4-12 part, butyl 2-4 part, zinc oxide 6-12 part, polyvalent alcohol 4-6 part, barium oxide 10-22 part, beta-diketon 4-7 part, monocarboxylic acid 10-14 part, organic additive 4-8 part.
The invention has the beneficial effects as follows: Rare earth composite heat stabilizer for PVC of the present invention, have excellent stability, weathering resistance, light stability, workability, energy consumption is low.
