Abstract

The invention relates to the technical field of textile materials, in particular to a halogen-free environment-friendly flame-retardant non-woven fabric preparation method. Flame retardants are prepared into flame-retardant size, a non-woven fabric is directly coated with the flame-retardant size, the preparation method is simple in process and high in production efficiency, and waste of the flame retardants is avoided. The prepared non-woven fabric is prepared from environment-friendly halogen-free brucite and has good flame-retardant effects, and the flame-retardant level is B1 and B2. As infusorial earth is used in the non-woven fabric, harmful substances in air can be effectively removed, an indoor living environment is improved in a targeted manner, and the mechanical property, the flame-retardant property and the heat stability of polymer are improved by the aid of montmorillonite.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a preparation method of a halogen-free environment-friendly flame-retardant non-woven fabric. Background technique [0002] The material of non-woven fabrics is mostly polypropylene, because its fibers have no fixed structure and are not made by weaving, so they are called non-woven fabrics. For example, it is widely used in masks, tablecloths, curtain wall materials, etc. In the application of these materials, sometimes they need to have better flame retardant properties. Since the raw materials of non-woven fabrics, such as polypropylene, are hydrocarbon materials, they are easy to burn. When encountering an open flame, burning may occur, which is harmful people's personal safety. To improve the flame retardant performance of non-woven fabrics, special processing and treatment of non-woven fabrics is required, such as using some flame-retardant substances to attach ...
