[0003] Polypropylene non-woven fabric is a kind of non-woven fabric. It is made of polypropylene through high-temperature wire drawing and polymerized into a net, and then bonded into a cloth by hot pressing. Due to the simple process and harmless to the human body, it is widely used in sanitary materials, In the field of clothing, glove interlining, etc., at present, the waste of disposable polypropylene non-woven fabrics is increasing, resulting in a large waste of resources. How to reuse non-woven clothing, reduce environmental pollution, and realize resource utilization has great economic benefits. Therefore, the present invention provides a kind of polypropylene composite material specially used for automobiles by using polypropylene non-woven fabric as raw material and compounding other additives.

Abstract

The invention relates to a special automobile polypropylene composite material added with a non-woven fabric reclaimed material. The special automobile polypropylene composite material is prepared from the following raw materials in parts by weight: 30-40 parts of polypropylene resin, 20-30 parts of high-impact polypropylene, 10-15 parts of non-woven fabric reclaimed fibers, 5-8 parts of modified silicon dioxide, 3-5 parts of a toughening agent and 1-3 parts of an antioxidant; the non-woven fabric reclaimed fibers are obtained by taking waste non-woven fabrics as a raw material and carrying out cleaning, alkaline leaching and grafting modification, the waste non-woven fabrics are taken as the raw material, so that secondary utilization of resources is realized, pollution of waste materials is reduced, modified silicon dioxide is combined with high heat conductivity and ultraviolet resistance of silicon dioxide, after the treatment of a coupling agent KH-550, the dispersing property of the composite material in the polymer is improved, and the polypropylene composite material prepared by the invention has the characteristics of low cost, environmental friendliness, high efficiency, impact resistance, high flame retardance, high heat dissipation and the like, and has great application value in automobile windshields, automobile lamps and automobile body shell plastics thereof.

Description

technical field [0001] The invention belongs to the technical field of polypropylene composite material preparation, and in particular relates to a special polypropylene composite material added with non-woven recycled materials. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties. , non-toxic, non-irritating, rich in color, low in price, recyclable, etc., are currently widely used as disposable clothing, non-woven materials can be divided into polypropylene, polyester, nylon, spandex, acrylic, etc. according to the composition; Different ingredients will have very different non-woven styles. [0003] Polypropylene non-woven fabric is a kind of non-woven fabric. It is made of polypropylene through high-temperature wire drawing and polymerized into a net, and then bonded into a cloth by hot pressing. Due to the simple process and harmle...
