Problems solved by technology

However, calcium-zinc heat stabilizers still have defects such as poor stabilizing effect, initial coloring, and "zinc burning", and the application effect is not ideal, so it is difficult to replace lead salt heat stabilizers, and auxiliary heat stabilizers need to be synergistic

Abstract

The invention relates to the field of heat stabilizers for PVC, in particular to a special low-odor phenol-free barium-zinc stabilizer for a toy film and a preparation method of the barium-zinc stabilizer. The stabilizer is prepared from components in parts by weight as follows: 100 parts of a main stabilizer, 10-15 parts of a porous thiophene polymer, 5-8 parts of a lubricant, 4-9 parts of a phenol-free antioxidant and 20-30 parts of an auxiliary stabilizer. The porous thiophene polymer is added to the formula and has higher BET value and high specific surface area, thereby having an enriching function and high adsorption capacity, heat stability during PVC processing is improved remarkably, and the probability of discoloration is low; by means of the rigid structure of the polymer, mechanical properties and weather fastness of a product can be improved; the preparation method of the heat stabilizer is simple, convenient to operate and environmentally friendly, and the prepared heat stabilizer has good heat stability and processability.

Description

technical field [0001] The invention relates to the field of heat stabilizers for polyvinyl chloride, in particular to a special low-odor phenol-free barium-zinc stabilizer for toy films and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) has the advantages of good processability, high strength, corrosion resistance, good insulation, and flame retardant, and is widely used in industrial and agricultural production. However, there are some defects in the PVC molecular chain, such as allyl chloride, etc. The processing temperature of PVC is generally above 170°C. At this high temperature, active Cl atoms such as allyl chloride are easily removed in the form of HCl, resulting in " "zipper" type chain reaction, making the color of PVC turn yellow or even black. And the generated HCl will further promote the thermal degradation of PVC. Therefore, heat stabilizers need to be added during PVC processing. Commonly used heat stabilizers include...
