Fireproof adhesive

Abstract

The invention belongs to an adhesive, and particularly relates to fireproof adhesive. The fireproof adhesive is characterized by comprising the following raw materials in parts by weight: 25-35 parts of sodium silicate, 15-25 parts of potassium metasilicate, 15-20 parts of powdered kaolin, 2-6 parts of titanium dioxide, 4-8 parts of aluminum hydroxide, 2-6 parts of phosphate powder, 4-8 parts of magnesium oxide powder, 3-5 parts of water, 2-3 parts of a water-repellent agent, and 6-9 parts of a 0p-10 emulsifier. The fireproof adhesive is compounded from various inorganic silicate, phosphate and inorganic flame retardants, is one-component and special for fireproof doors and anti-theft doors, and has the characteristics that the fireproof adhesive is high-temperature resistant, nontoxic, free of contamination and simple and convenient to operate on site.

Description

technical field [0001] The invention belongs to an adhesive, in particular to a fireproof adhesive. Background technique [0002] Polymer adhesives are used in all fields due to their superior bonding properties, but they have disadvantages such as high toxicity, poor temperature resistance, high price, and high cost of use, so they have been widely used in many fields. limits. Due to its non-combustible, high temperature resistance, rich raw materials, low price, and no environmental pollution, inorganic adhesives are widely used in more and more fields. However, this kind of fireproof adhesive needs to degrease the surface of the steel plate before operation. Or phosphating treatment, so the operation is cumbersome, the bonding strength is low, the gum is brittle, and the drying time is long. In addition, this traditional inorganic adhesive can be pressed for 2-3 hours with a traditional cold press to form the fire door, thus prolonging the production period of the fire ...
