Flame retardant and preparation method thereof, and flame retardation products

Abstract

The invention relates to a flame retardant, a preparation method thereof and a flame retardant product. The basic feature of the flame retardant is one or more of the following substances: borax, boric acid, phosphoric acid, ammonium sulfate, sodium molybdate, Ammonium dihydrogen phosphate, diammonium hydrogen phosphate, triammonium phosphate, ammonium polyphosphate, guanidine phosphate, memidylurea phosphate, phosphoric acid ester, melamine phosphate, melamine pyrophosphate, aluminum hydroxide, magnesium hydroxide, zinc hydroxide, Urea-formaldehyde resin, melamine-modified urea-formaldehyde resin, melamine resin, melamine-formaldehyde resin. The weight percentage of the phosphorus-nitrogen flame retardant, the inorganic flame retardant and the amino resin is 1:0-100:0-100. The flame retardant forms include flame retardants, coated new flame retardants, flame retardant adhesives, flame retardant adhesives, and flame retardant materials. The flame retardant of the present invention has good fire-resistance performance in the application of the flame-retardant process, and can reduce the combustion smoke concentration and toxicity of the flame-retardant material under fire.

Description

Technical field [0001] The invention relates to a flame retardant, a preparation method thereof and a flame retardant product. Background technique [0002] The compulsory standard of "Fire-retardant products and components in public places" (GB20286-2006) compulsory standard stipulates that products and components entering public places must have a certain level of flame-retardant performance. A considerable part of products used in households and public places are flammable materials, which constitute a hidden danger of building fires. With the popularization of flammable materials in homes and public places, fire safety issues have become more prominent. For the safety of human life and property, it is necessary to use flame-retardant materials with flame-retardant function, and it is also the most concerned issue in the industry. [0003] The Ministry of Public Security and the Ministry of Construction promulgated and implemented the "Code for Fire Protection Design of Buildi...

Problems solved by technology

Phosphorus-nitrogen compounds have good flame retardant properties, wide sources, and low prices, but the main problem of using phosphorus-nitrogen compounds to produce flame-retardant plant fiberboards is: compared with ordinary fiberboards of the same specification, the mechanical properties are reduced by 15-45%; Hygroscopicity and water absorption thickness expansion rate increase, which cannot meet the processing and use requirements; at high temperature, phosphorus-nitrogen compounds promote dehydration and carbonization of wood components into inactive carbon, resulting in an increase in the concentration of carbon monoxide in the smoke, making the smoke in the fire more harmful. increase

The addition of a large number of inorganic materials seriously damages the processing performance and performance of plant fiberboard
