Abstract

The invention provides a potassium silicate binder. The potassium silicate binder is characterized by comprising raw materials in parts by mass as follows: 30-50 parts of potassium silicate, 8-14 parts of white carbon black, 14-28 parts of magnesium oxide, 5-10 parts of magnesium chloride, 5-10 parts of magnesium sulfate, 5-10 parts of condensed aluminum phosphate, 2-8 parts of peregal O and 6-12 parts of water. The potassium silicate binder has the advantages as follows: the price is low, the application range is wide, normal-temperature curing is realized, water resistance is good, high temperature resistance is realized, flame retardancy is good, binding strength is high, the raw materials are foamed, the dosage is saved, the cost is reduced and the like.

Description

technical field [0001] The invention belongs to the technical field of bonding materials, in particular to a potassium silicate bonding agent. Background technique [0002] With the improvement of social economy and living standards, binders are playing an increasingly important role in people's daily life and production. At present, most of the binders on the market are organic binders. However, organic binders will cause some environmental pollution problems in the process of production and use, which will cause great harm to human health and the environment. Moreover, the organic binder has poor high temperature resistance and is easy to burn, so the fire resistance is poor. So these disadvantages limit the further application of organic binders. The inorganic binder not only has excellent high temperature resistance, but also does not produce harmful substances to pollute the environment during the production and preparation process. The most widely used inorganic bin...
