Abstract

The invention discloses an organic complex zinc environment-friendly compound stabilizer for PVC (polyvinyl chloride) and a method for preparing the organic complex zinc environment-friendly compound stabilizer. The organic complex zinc environment-friendly compound stabilizer comprises, by weight, 60-80 parts of zinc salt stabilizers, 1-7 parts of isolated soybean proteins, 5-20 parts of epoxy compounds, 5-15 parts of rare earth oxide, 10-35 parts of hydrotalcite, 8-20 parts of thiocarbanilide, 1-9 parts of antioxidants, 1-5 parts of ultraviolet absorbents, 1-2 parts of organic lubricants and 20-60 parts of fillers. The organic complex zinc environment-friendly compound stabilizer and the method have the advantages that the zinc salt stabilizers are used as main stabilizers, other raw materials are added into the zinc salt stabilizers and are used as auxiliary materials, accordingly, the organic complex zinc environment-friendly compound stabilizer for the PVC can be obtained and is high in transparency, and excellent heat stabilization effects can be realized by the organic complex zinc environment-friendly compound stabilizer.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an organic complex zinc environmental protection composite stabilizer for PVC and a preparation method thereof. Background technique [0002] Polyvinyl chloride PVC is one of the three general-purpose plastics in the world, and its output is second only to PE. With its advantages of high strength, plasticity, corrosion resistance, flame retardant, good insulation, good transparency, etc., it is widely used in industry, agriculture, daily necessities, electric power, etc. field. However, PVC still has the disadvantages of poor thermal stability and easy degradation. [0003] Among them, due to the deficiency of the PVC molecular chain itself, the chlorine group is unstable, and PVC with no matter isotactic or random structure is easily decomposed by heat to decompose from HCl. And HCl becomes a catalyst to cause a chain reaction to aggravate the degradation of PVC, thereby caus...
