Problems solved by technology

At present, the more common flame retardants are halogen flame retardants and phosphorus flame retardants, but the application of halogen flame retardants is greatly restricted because of the production of toxic substances in the combustion process, so phosphorus flame retardants It is a relatively safe and environmentally friendly flame retardant material
Generally, phosphorus-based flame retardants are a single phosphorus-based compound, which has certain deficiencies in flame-retardant effect and melting dripping.

Abstract

The invention discloses a phosphorus hybrid flame retardant and a preparation method thereof. The flame retardant comprises the following raw materials by weight: 100 parts of 2-hydroxyethyl phenyl phosphinic acid, 30-50 parts of a graphene polyphosphazenes nano composite material, 10-15 parts of montmorillonite, 10-20 parts of sodium methylsiliconate, and 50-80 parts of inositol hexaphosphate. The phosphorus hybrid flame retardant provided by the invention is mainly composed of phosphorus 2-hydroxyethyl phenyl phosphinic acid, with other components added to the compound so as to obtain the hybrid flame retardant. Components of the flame retardant cooperate and synergize with each other, which overcomes the defect that single phosphorus compounds are liable to generate melted droplets and have poor water resistance. The flame retardant has the advantages of simple preparation, good thermal stability, good water resistance and high flame retardancy.

Description

technical field [0001] The invention relates to a flame retardant mixture for textile use and a preparation method thereof, in particular to a phosphorus-based mixed flame retardant and a preparation method thereof, and belongs to the technical field of flame retardants. Background technique [0002] With the development of modern science and technology and the textile industry, there are more and more types of textiles, and they are more and more widely used in human daily life. However, textiles are generally flammable or combustible materials, and many fires are caused by textiles. Caused or amplified by ignition. According to statistics, the number and death rate of fires caused by textiles are higher than those caused by other causes. About 20% of the fires in the world are caused by the burning of textiles. Therefore, the flame retardant problem of textiles has become the focus of widespread attention in the world. [0003] In order to reduce the flammability of text...
