Fireproof bonding glue and production process thereof

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.

Description

technical field [0001] The invention relates to a chemical product, in particular to a fireproof adhesive and its production process. Background technique [0002] At present, the production raw materials of fireproof adhesive adhesives on the market contain organic materials, which will produce black smoke during use and cause harm to human health; Affect the health of the human body and cause adverse effects on the surrounding environment. In addition, it does not comply with the provisions of the Fire Protection Act. Generally, the addition of inorganic materials will affect the bonding performance of the adhesive, and it will easily fall off after a long time; it will also affect the curing speed of the fireproof adhesive, as well as the characteristics of acid, alkali and salt resistance. Contents of the invention [0003] In order to produce an environmentally friendly, non-toxic and good cohesive fireproof adhesive, the technical solution adopted by the present inv...
