Abstract

An improved wood fire retardant is prepared from the following raw materials in parts by weight: 7-10 parts of tetrakis hydroxymetyl phosphonium sulfuric, 3-8 parts of phosphoric acid, 7-11 parts of solid sodium bicarbonate, 6-9 parts of calcium hydroxide, 5-7 parts of ammonia water, 8-12 parts of methenamine, 7-10 parts of ammonium sulfate, 3-6 parts of boric acid, 7-9 parts of urea, 6-10 parts of copper sulfate, 3-10 parts of zinc chloride and 6-11 parts of bentonite. The improved wood fire retardant has the benefits that good inflaming retarding and combustion suppressing effect is achieved, and at the same time decay resistance and vermin-proof performance are achieved and the action time is long.

Description

technical field [0001] The invention relates to a modified wood flame retardant. Background technique [0002] Wood and its products are a kind of natural polymer materials with excellent performance, especially with the advantages of natural and beautiful texture, temperature and humidity adjustment, etc., they are widely used in interior decoration, furniture manufacturing, house construction and exterior decoration. However, since wood is a flammable material, the fire protection requirements for people are more stringent. Wood flame retardants are additives that prevent wood from being ignited and inhibit the spread of flames. Has a wide range of use. However, the existing flame retardants have the defect of insufficient performance, and cannot meet the needs of people. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide a modified wood flame retardant, which has a good flame...
