Embodiment 1

[0052] cotton textiles

[0053] The oxygen index of cotton cloth treated with this flame retardant fire extinguishing agent is as high as 52. Properly reduce the concentration and control its oxygen index at about 32, which can meet the fire protection requirements. Its use is mainly for flame retardant treatment of decorative fabrics such as theaters and dance halls.

Embodiment 2

[0055] wood

[0056] The oxygen index of woodblocks treated with this flame retardant fire extinguishing agent can reach more than 40. One of its uses is to make flame-retardant packaging boxes (such as packaging boxes for explosives and flammable and explosive items); the other is to make flame-retardant wood partition walls (suitable for high-rise buildings)

Embodiment 3

[0058] the paper

[0059] The flame retardant and fire extinguishing agent can be added to the paper by selecting an appropriate process link in the papermaking process to make the paper flame retardant. Its use is as a paper with long-term preservation value for archives, bills, documents, etc.; and as a base material for flame-retardant packaging cartons.

Abstract

The macromolecular flame-retardant fire-extinguishing agent is made up by using water soluble substrate containing anion group through the processes of cross-linking and grafting, adding correspondent flame-retardant active substrate, and mixing them with water. It is high in fire-extinguishing effect, and its performance is stable and cost is low.

Description

(1) Technical field [0001] The invention relates to a polymer flame retardant fire extinguishing agent and its preparation process in the field of fire safety. After the corresponding flame retardant active substance is mixed with water, a new type of polymer liquid flame retardant fire extinguishing agent that can inhibit the dispersion and migration of fire is formed. It has the characteristics of high water content, quick setting, flame retardant, non-toxic, tasteless, simple proportioning, good wall attachment performance, low comprehensive cost, and environmental protection function. It integrates multiple fire extinguishing mechanisms of cooling, suffocation, isolation and chemical inhibition, and acts simultaneously to block the three major elements of combustion. It is a flame retardant fire extinguishing agent with strong reflammability and the ability to efficiently extinguish Class A and Class B fires. [0002] Fire is one of the major disasters that endanger huma...
