Problems solved by technology

[0004] Chinese patent application number 200610028214.5 discloses a liquid flame retardant liquid for foaming. The flame retardant is easy to fall off during use, resulting in reduced flame retardant performance, poor flame retardant effect, and low production efficiency due to discontinuous production.
However, in the long-term use process, the migration and precipitation of flame retardants and the change in the performance of soft polyurethane foam products are problems to be solved

Abstract

The invention relates to a halogen free flame retardant liquid and a method for preparing a flame retardant sponge using the same. The halogen free flame retardant liquid has the flame retardant effect up to a UL V-0 grade, durable flame retardant effect and no smoke toxicity and comprises 100 parts of water based adhesive, 0.5-5 parts of curing agent, 0.1-5 parts of anti-settling agent, 0-2 parts of color fixing agent, 0-100 parts of colorant, 100-300 parts of environment-friendly flame retardant, 100-400 parts of inorganic flame retardant and 1200-1800 parts of water, wherein the anti-settling gent is at least one of organic modified bentonite, fumed silica, polyethylenewax, polyamide wax or titanate coupling agent, and the environment-friendly flame retardant is at least one of phosphorus flame retardant or phosphorus and nitrogen flame retardant. The method for preparing the flame retardant sponge comprises the step of immersing an open-cell sponge in the above halogen free flame retardant liquid and drying to obtain the product. The halogen free flame retardant liquid can be obtained through a conventional mixing process, and the method for preparing the flame retardant sponge is simple, can be in continuous production, improve production efficiency and lower cost.

Description

technical field [0001] The invention relates to a halogen-free flame retardant liquid and a method for preparing a flame retardant sponge using the halogen-free flame retardant liquid. Background technique [0002] Due to the increasing calls for flame retardant and disaster prevention worldwide and the establishment and development of legislation in the field of environmental protection, the research, development, production and application of flame retardant materials have been directly promoted. [0003] Traditional flame retardant materials widely use halogen-containing polymers or flame-retardant mixtures composed of halogen-containing flame retardants. However, once a fire breaks out, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases will be produced, which will hinder fire fighting and personnel evacuation, and corrode instruments and equipment. In particular, it has been found that more than 80% of fatal accidents in fire...
