Corrosion-resistant physical and chemical board for laboratory

Abstract

The invention discloses a corrosion-resistant physicochemical plate for laboratories, which comprises the following components in parts by weight: 90-100 parts of physicochemical substrate, 5-10 parts of physicochemical membrane and 0.5-1 part of adhesive. The physicochemical substrate and physicochemical membrane are bonded through an adhesive. The physicochemical substrate is prepared from the following raw materials in parts by weight: 40-50 parts of kraft, 50-70 parts of modified phenol formaldehyde resin, 5-8 parts of curing agent and 1-3 parts of buffering agent. The physicochemical membrane is prepared from the following raw materials in parts by weight: 25-30 parts of vinyl ester resin, 14-17 parts of dimethyldiethoxysilane, 10-15 parts of phenol formaldehyde resin, 1-4 parts of silicon carbide fiber, 35-40 parts of ceramic powder and 2-5 parts of titanium white. The corrosion-resistant physicochemical plate for laboratories has the advantages of low cost, excellent corrosion resistance, excellent 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 physical and chemical plate for laboratories. 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 physical and chemical plate for laboratory use, which has long...
