Abstract

The present invention relates to the technical field of PVC materials, in particular to the application of tris(2-hydroxycyclohexyl) isocyanurate in PVC composite heat stabilizers and the PVC products prepared by using it. The above-mentioned tris(2-hydroxycyclohexyl) PVC products prepared from isocyanurate, including the following raw materials in parts by weight: 100 parts of PVC resin, 20-60 parts of dioctyl phthalate, 0.5-5 parts of environmentally friendly composite heat stabilizer, tris(2-hydroxyl ring Hexyl) isocyanurate 0.1~1 part. The PVC product prepared by using tris(2-hydroxycyclohexyl) isocyanurate in the present invention has good thermal stability and excellent heat resistance performance. After the thermal stability test, the initial coloring effect of the sample can reach 0-1 grade, which is obviously high. PVC products prepared from existing heat stabilizers.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to the application of tris(2-hydroxycyclohexyl)isocyanurate in PVC composite heat stabilizers and PVC products prepared by using the same. Background technique [0002] The structure of polyvinyl chloride (PVC) has defects, and it is easily degraded under the action of heat and mechanical shear, releasing HCl, deepening the color, reducing the mechanical properties, and losing its use value. Therefore, heat stabilizers must be used in the processing of PVC. Heat stabilizers mainly include lead salts, [0003] Organic metal soaps, organotin, composite stabilizers, organic heat stabilizers, etc. Although lead salt stabilizers have excellent thermal stability, they are highly toxic and harmful to human health, and their use has been gradually banned or restricted at home and abroad. Metal soap stabilizers are usually used together, and they are easy to precipitate during proces...
