Light-weight high-toughness PVC foamed trough plate for display panel

Abstract

The invention discloses a light-weight high-toughness PVC foamed trough plate for a display panel. The trough plate comprises the following raw materials in parts by weight: 50-70 parts of PVC resin, 4-8 parts of polytetrafluoroethylene, 4-10 parts of polypropylene, 0.8-1.2 parts of dibenzoyl peroxide, 1.5-2.5 parts of 2-thiol benzimidazole, 0.3-0.9 part of pyromellitic dianhydride, 1.5-2.5 parts of coal tar, 0.4-1 part of dibutyl phthalate, 1.5-2.5 parts of stearic acid, 1-2 parts of triphenyl phosphate, 0.4-1 part of disproportionated rosin, 4-8 parts of ceramic microspheres, 4-8 parts of polyamide fibers, 3-7 parts of glass beads, 20-30 parts of zeolite power compound kapok fibers, 4-8 parts of a silane coupling agent KH550, 6-10 parts of white carbon black, 4-8 parts of magnesium hydroxide, 3-7 parts of a foaming agent, 1.5-2.5 parts of an ultraviolet absorbent and 1-2 parts of an anti-aging agent.

Description

technical field [0001] The invention relates to the technical field of PVC, in particular to a light-weight and high-toughness PVC foaming groove plate for display boards. Background technique [0002] Display boards are generally fixed on display walls or display racks for displaying or selling items. In the prior art, the display board is a large board with a hanging groove on the display board, and the articles are hung on the hanging groove through the hanging parts. Because the PVC foam groove board is light in weight and has good flexibility, it is widely used in the display board, but the traditional The hardness of the PVC foam groove board is low. Although there is a high-strength PVC foam board, the quality is heavy and cannot meet the requirements of the wall hanging of the exhibition board. It is easy to fall off. How to make a light weight and good wear resistance, The cost of using light weight and high toughness PVC foamed channel panels for display panels wi...
