Fire retardant

Abstract

The invention provides a fire retardant which comprises the following components in percentage by weight: 60%-80% of ammonium dihydrogen phosphate, 10%-35% of diammonium hydrogen phosphate, 0.5%-2% of lauryl sodium sulfate and the balance of urea. The preparation method comprises the following steps of: placing 4 raw material components to a stirrer in proportion; and uniformly stirring for 20 minutes. The fire retardant provided by the invention is an environmental-friendly product without toxicity or corrosiveness, has the advantages of better fireproof effect, low price and convenience for use and can be soaked or sprayed. According to the invention, the fire retardance of a material treated through the fire retardant can achieve the national standard of flame resistance B1. The fire retardant provided by the invention is widely used for various decorative fabrics, non-woven fabrics, industrial fabrics and clothes fabrics and the fields of wooden splints, paper boxes, and the like; the product provided by the invention can be used for providing safe and reliable fireproof guarantee for high-rise buildings, public amenities, hotels, residential buildings, and the like.

Description

technical field [0001] The invention relates to a functional additive for flammable polymers, in particular to a flame retardant. Background technique [0002] Flame retardants are also known as flame retardants, fire retardants or fireproofing agents: functional additives that impart flame retardancy to flammable polymers; they are divided into additive flame retardants and reactive flame retardants according to the application method. According to the composition, additive flame retardants mainly include inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides), phosphorus flame Department of flame retardants, etc. [0003] Flame retardants currently mainly include organic and inorganic, halogen and non-halogen. Organic is some flame retardants represented by bromine, phosphorus nitrogen, nitrogen and red phosphorus and compounds, and inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flam...
