Abstract

The invention discloses a rare earth heat stabilizer for a high-transmittance PVC (polyvinyl chloride) product and a preparation method of the rare earth heat stabilizer, and relates to the technical field of heat stabilizers. The invention discloses a rare earth heat stabilizer for a high-transmittance PVC (polyvinyl chloride) product and a preparation method of the rare earth heat stabilizer. The rare earth heat stabilizer is prepared from the following raw materials in parts by weight: 20-40 parts of a mixed solution of a rare earth salt solution and tin salt, 0.01-0.12 part of a precipitator, 20-40 parts of lanthanum ricinoleate, 20-85 parts of calcium stearate, 10-50 parts of zinc stearate, 5-20 parts of pentaerythritol, 5-20 parts of beta-diketone and 0.01-0.12 part of a dispersing agent. According to the rare earth heat stabilizer for the high-transmittance PVC product and the preparation method of the rare earth heat stabilizer, through the synergistic effect of the rare earth, the rare earth and the calcium-zinc stabilizer complement each other, the problem that the stability is poor when trivalent lanthanum and chloride ions generate a positive complex is solved, the stabilizing effect can be greatly improved, the process steps are simplified, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of heat stabilizers, in particular to a rare earth heat stabilizer for high-permeability PVC products and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose resins in the world. Its products have the advantages of easy adjustment of softness and hardness, high mechanical properties, corrosion resistance, good electrical insulation, high transparency and low price, and are widely used in industry and agriculture. and other production areas. However, the stability of PVC is poor, and it is prone to degradation and cross-linking reaction under the action of external factors such as heat, light, oxygen and force, which makes processing and use difficult, the color of the product deepens, and the mechanical properties decline. In order to solve this problem, a certain amount of heat stabilizer must be added during the processing of PVC to form ...
