Abstract

The invention discloses a chemical corrosion-resistant table rubber sheet, a preparation method and applications thereof. The table rubber sheet mainly consists of the following raw materials by weight percentage: 2 percent to 40 percent of anhydride curing agent, 2 percent to 40 percent of other types of acid anhydrides, 2 percent to 50 percent of epoxy resin systems, 40 percent to 93 percent of filler and 0.01 percent to 1 percent of initiator, wherein, the anhydride curing agent is maleic anhydride and the initiator is hydroperoxide or dialkyl peroxide. The preparation method of the invention includes the steps that maleic anhydride is introduced in common acid anhydrides and added with a peroxide initiator to initiate the free radical polymerization and form an interpenetrating network structure so as to improve the heat distortion temperature of products. Meanwhile, by adopting the preparation method of the invention, the products can be made from raw materials with lower prices, thus having relatively high market competitiveness. When being applied to an experiment table top in a laboratory, the table rubber sheet of the invention can has relatively good flatness on the sheet surface, good wearing resistance and chemical corrosion resistance as well as comparatively high heat distortion resistance.

Description

Technical field [0001] The invention relates to an artificial stone slab product, in particular to an epoxy resin-based chemical corrosion-resistant countertop rubber sheet, and a preparation method and application thereof. Background technique [0002] At present, the materials that can be used as countertops on the market are natural marble, granite, stainless steel, fireproof board, ceramic tile, physical and chemical board and artificial stone countertop. These materials have disadvantages of one kind or another when used in laboratories or other chemical-resistant applications. Natural marble, granite and ordinary ceramics have poor resistance to acid and alkali corrosion, and are relatively brittle; stainless steel products not only have poor decorative effects, but are also easy to scratch and have insufficient corrosion resistance; ordinary fireproof boards have corrosion resistance and high temperature resistance. The repairability is poor; the physical and chemical plat...
