High-temperature-resistant flame-retardation slurry

Abstract

A disclosed high-temperature-resistant flame-retardation slurry is characterized by comprising the following raw materials in parts by weight: 15-20 parts of unsaturated polyester resin, 6-8 parts of polyvinyl fluoride, 12-15 parts of rock wool, 6-8 parts of asbestos clay, 6-8 parts of white clay fiber, 3-5 parts of Ammonium dihydrogen phosphate, 3-5 parts of diammonium hydrogenphosphate, 0.6-0.8 part of a dispersant, 1.4-1.8 parts of zinc oxide, 2-3 parts of modified silica sol, 2-4 parts of urea, 3-5 parts of calcium carbonate, 2-4 parts of a filling material, and 0.8-1.2 parts of an auxiliary agent. The flame-retardation slurry prepared according to the formula is an environment-friendly product, is nontoxic and free of corrosiveness, possesses the flame resistance up to A grade standard, is good in fireproof effect, is widely applicable to the technical field of decoration, and is good in wettability and thereby possessing good wettability on fiber products. The flame-retardation slurry is adjustable in viscosity and long in service life, is improved in high-temperature resistance because of addition of the filling material, and possesses wide market application value.

Description

technical field [0001] The invention belongs to the technical field of flame retardant materials, and in particular relates to a high temperature resistant flame retardant slurry. Background technique [0002] Fireproof board is the most commonly used material on the market at present. There are two commonly used types: one is high-pressure decorative fire-resistant board, which has the advantages of fireproof, moisture-proof, wear-resistant, oil-resistant, easy to clean, and has many varieties of designs and colors; the other is glass magnesium fire-resistant board, the outer layer is decorative material, and the inner layer is The first layer is mineral glass magnesium fireproof material, which can resist high temperature of 1500 degrees, but the decoration is not strong. The installation of fire-resistant suspended ceilings in building exit passages, stairwells and corridors can ensure the safe evacuation of people in the event of a fire and protect people from spreading...

AI Technical Summary

Problems solved by technology

The disadvantages are that the construction is difficult, the bonding strength is poor, and it cannot meet the requirements of Class A fireproof materials.

Although the vinyl ester resin in the prior art has the advantages of good toughness, good bonding strength, and low toxicity after curing, it has the disadvantages of low service temperature; although epoxy resin has the advantages of good toughness and high bonding strength, it has There are poor weather resistance, easy pulverization, high viscosity, and poor wettability. Therefore, how to produce a high temperature resistant flame retardant slurry has important practical significance
