Abstract

The invention relates to a chemical product, in particular to fireproof bonding glue and a production process thereof. For producing the environment-friendly nontoxic fireproof bonding glue with good bonding property, the invention adopts the technical scheme that the fireproof bonding glue comprises the following components in percentage by mass: 48 percent of aluminium powder, 48 percent of sodium silicate, 10 percent of sodium polyphosphate, 2 percent of methylcellulose, 10 percent of sodium methyl silicate and 10 percent of tap water. The production process comprises the following steps: adding 48 percent by mass of sodium silicate and 10 percent by mass of water into 48 percent by mass of aluminium powder; putting the mixture into a reaction kettle to stir and heat, wherein the heating temperature is between 65 and 68 DEG C; preserving temperature for 3 hours to carry out polymerization; after polymerization is completed, adding 10 percent by mass of sodium polyphosphate into a reaction product to carry out neutralization, wherein the neutralization time is 15 minutes; additionally adding 2 percent by mass of methylcellulose and 10 percent by mass of sodium methyl silicate into the obtained product to stir for five minutes; and carrying out coarse grinding twice and carrying out fine grinding once on the stirred liquid raw materials to obtain the fireproof bonding glue.
