Organic boron antiflaming finishing agent for fabrics and preparation method thereof

Abstract

The invention discloses an organic boron antiflaming finishing agent for fabrics and a preparation method thereof. The organic boron antiflaming finishing agent for fabrics is prepared by raw materials of boric acid, diethanol amine, phosphorous acid and epoxy chloropropane. The structure is shown in the right formula, and the organic boron antiflaming finishing agent has the advantages of safety, non-toxicity, favorable antiflaming performance, good waterproof washing and no toxicity substance in the burning process, and the finished fabrics cannot release free formaldehyde and haloid elements.

Description

technical field The invention relates to an organic boron flame retardant finishing agent and a preparation method thereof, which is an organic borate compound and is suitable for flame retardant finishing of various natural fibers and synthetic fibers. Background technique With the development of science and technology, the progress of the textile industry, the variety of textiles is increasing, and the scope of its application is also expanding. Due to the flammability of textiles, it is common for textiles to catch fire and spread during fire accidents. Textiles, especially chemical fiber products, emit pungent toxic fumes when they are burned. According to the research of the European Flame Retardant Association (EFRA), a large part of the people who die in fires every year are suffocated by toxic fumes. Therefore, how to reduce the danger of textile combustion and the release of toxic gases during combustion, and reduce the loss of people's lives and property, has bee...

AI Technical Summary

Problems solved by technology

Traditional flame retardants are mostly based on halogens, antimony, phosphorus, nitrogen and other elements. Although they have relatively good flame retardant properties, they have defects such as high toxicity of the product itself, toxic substances produced during combustion, hard hand feeling, and poor application performance.

N-dimethylolphosphonoacrylamide (NMDPPA, trade name Pyrovatex CP, referred to as flame retardant CP) developed by Ciba Specialty Chemical Co., Ltd. is an excellent flame retardant, which has excellent resistance to natural fibers such as cotton. Inflammability and washing resistance, but as a phosphorus and nitrogen composite flame retardant, the product itself has certain toxicity, and the textiles it finishes will release free formaldehyde, and generate certain smoke and dust during the combustion process
