A corrosion-resistant heat-resistant physical and chemical board

Abstract

The invention discloses a corrosion-resistant and heat-resistant physical and chemical board, which comprises: 80-90 parts of physical and chemical base material, 4-8 parts of physical and chemical film and 0.6-0.9 parts of adhesive in parts by weight. The physical and chemical base material and the physical and chemical film are glued together. The raw materials of physical and chemical substrates include by weight: 50-60 parts of wood fiber, 30-40 parts of modified phenolic resin, 2-4 parts of curing agent, and 1-2 parts of buffering agent; the raw materials of physical and chemical film are by weight Parts include: 30-50 parts of vinyl ester resin, 5-10 parts of dimethyldiethoxysilane, 20-30 parts of phenolic resin, 1-3 parts of alumina fiber, 35-40 parts of kaolin, 1-10 parts of titanium dioxide 2 servings. The invention has low cost, excellent corrosion resistance and heat resistance, and long service life.

Description

technical field [0001] The invention relates to the technical field of physical and chemical plates, in particular to a corrosion-resistant and heat-resistant physical and chemical plate. Background technique [0002] With the gradual increase of laboratory equipment at present, the physical and chemical board used in the laboratory is used more and more widely as an indispensable material. Phenolic resin has high bonding strength, water resistance, heat resistance, wear resistance and good chemical stability. Due to its advantages, it is widely used in the physical and chemical board industry, but it has disadvantages such as high cost, high curing temperature and long curing time. The current physical and chemical boards are increasingly unable to meet market demand in terms of corrosion resistance, heat resistance and service life. Contents of the invention [0003] The invention provides a corrosion-resistant and heat-resistant physical and chemical board, which has lo...
