Abstract

The invention belongs to the technical field of PVC (polyvinyl chloride) heat stabilizers, particularly relates to a heat stabilizer for processing soft transparent PVC and a preparation method of the heat stabilizer, and can solve the technical problem that the existing heat stabilizer technology cannot give consideration to both initial coloring and long-term heat stability in PVC processing. The heat stabilizer for processing the soft transparent PVC is characterized by comprising the following raw materials: zinc oleate, an amino metal organic framework compound, an auxiliary heat stabilizer, a plasticizer, a lubricant, an antioxidant and an ultraviolet light absorber. Zinc oleate and an amino metal organic framework compound are used as main stabilizers, necessary auxiliary stabilizers are matched, and compared with traditional zinc stearate, the transparent PVC material has excellent transparency and initial coloring and is suitable for transparent PVC products.

Description

technical field [0001] The invention belongs to the technical field of PVC heat stabilizers, and in particular relates to a heat stabilizer for processing soft transparent PVC and a preparation method thereof. Background technique [0002] Common products of transparent PVC include plates, pipes, sheets and films. The hardness can be adjusted to meet the performance requirements of transparent cables, soft toys, stationery, food packaging films, artificial leather products, etc., and develop high transparency and low temperature. Soft PVC products are research hotspots in this field. When processing transparent PVC, heat stabilizers, plasticizers and lubricants should be added, among which heat stabilizers play a vital role in the initial coloring and long-term thermal stability of PVC products. [0003] The plasticizing and decomposition temperatures of PVC resin are very close, and its processing temperature is usually higher than 140°C, and it will decompose at about 100...
