Problems solved by technology

Because fatty acid calcium salts have serious pressure-separation properties, and fatty-acid zincs have serious blooming phenomena, the existing calcium-zinc composite stabilizer products have obvious problems such as pressure-separation and blooming, which limits their wide application in the PVC field.

Abstract

The invention relates to a powdery zinc base composite heat stabilizer and a preparation method thereof, and especially relates to a powdery zinc base composite heat stabilizer for polyvinyl chloride and a preparation method thereof. The composite heat stabilizer is prepared from the following components in parts by weight: 35 to 55 parts of zinc base complex, 10 to 20 parts of zinc burning inhibitor, 10 to 20 parts of auxiliary heat stabilizer, 5 to 10 parts of compatilizer, 5 to 15 parts of inorganic aid, and 5 to 10 parts of diethylene glycol monobutyl ether; wherein the zinc base complex is a composition of zinc acetylacetonate, zinc glycinate, zinc p-tert-butyl benzoate, and mercaptoacetic acid reverse thioester zinc; and the auxiliary heat stabilizer is a mixture composed of any two components of tri(glycidyl) isocyanurate, methyl silicone oil, benzyl carbazate according to any ratio. Compared with the conventional powdery calcium-zinc heat stabilizers, the provided powdery zinc base composite heat stabilizer does not contain any sodium aliphatate or zinc aliphatate, thus the heat stabilizer will not be precipitated easily, the blooming is difficult to happen, and the problem that conventional calcium-zinc heat stabilizers are precipitated and bloomed on the surface of colorful PVC products is solved.

Description

technical field [0001] The invention relates to a powder zinc-based composite thermal stabilizer and a preparation method, in particular to a powder zinc-based composite thermal stabilizer for polyvinyl chloride and a preparation method. Background technique [0002] At present, the heat stabilizer with the largest amount of use in my country's polyvinyl chloride (PVC) product industry is lead-containing heat stabilizer, with an annual consumption of about 600,000 tons. As the global awareness and requirements for ecological environmental protection increase, lead-containing heat stabilizers will face a situation of being completely banned. The development of high-efficiency green stabilizers has become a major technical bottleneck restricting the sustainable and healthy development of the PVC product industry. Calcium-zinc composite heat stabilizer has been highly valued by the industry due to its good thermal stability efficiency and environmental friendliness, and has a g...
