Easily-decomposed flame-resistant temperature-adjusting environmental-friendly non-woven fabric, and preparation method thereof

Abstract

The invention discloses an easily-decomposed flame-resistant temperature-adjusting environmental-friendly non-woven fabric, and a preparation method thereof. The easily-decomposed flame-resistant temperature-adjusting environmental-friendly non-woven fabric is prepared from, by mass, 2000 parts of polypropylene, 5 to 10 parts of a coupling agent, 5 to 10 parts of silicone oil, 1 to 5 parts of a nano-meter flame retardant, 3 to 8 parts of a carrier resin, 50 to 100 parts of a phase change temperature adjusting element, and an appropriate amount of high purity water. According to the preparation method, easily-decomposed cheap raw materials are used for preparing the easily-decomposed flame-resistant temperature-adjusting environmental-friendly non-woven fabric; reasonable mixing of the nano-meter flame retardant with the phase change temperature adjusting element is carried out; a slurry liquid is prepared via mixing with other assistant agents; spraying is adopted directly; and the non-woven fabric with excellent flame resistance and temperature adjusting performance is obtained on a cloth body.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to an easily decomposable, flame-retardant, temperature-adjusting and environment-friendly non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric (English name: NonWoven), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating. Non-toxic, rich in color, low in price, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. At present, non-woven fabrics are mainly flame-retardant by adding b...

AI Technical Summary

Problems solved by technology

At present, non-woven fabrics are mainly flame-retardant by adding bromine and antimony-containing compounds, or by adding hydroxides, phosphorus-containing flame retardants and other halogen-free substances to achieve flame retardancy. The former produces harmful substances that pollute the environment after burning, and the latter The flame retardant performance is not good enough, and the process performance of polypropylene raw materials is reduced

Since the raw materials of non-woven fabrics, such as polypropylene, are hydrocarbon materials, which are easy to burn, the current process of making flame-retardant non-woven fabrics is usually to soak the non-woven fabrics in a flame retardant solution for a period of time, then take them out and dry them. The process is long and it is easy to cause waste of flame retardant solution. At present, in the domestic market, there are temperature-regulating fibers made of sliced ​​fibers containing a small amount of temperature-regulating elements through spinning, and then woven into cloth or spun into temperature-regulating yarns. Although it has less temperature regulation function, it does not have flame retardant function

In the international market, there are temperature-regulated non-woven fabrics coated on non-woven fabrics. The coating is irregular square, but it does not have flame retardant function.
