Problems solved by technology

[0003] The foamed rubber used as EPDM rubber has good heat resistance but insufficient flame retardancy, and epichlorohydrin rubber used as other foam rubber has good flame retardancy but insufficient heat resistance, making it There are many restrictions on the scope of use
At present, the existing automotive interior materials are mainly flame-retardant polypropylene materials, and most of the flame-retardant materials contain halogens, which are more harmful to the environment. Therefore, environmentally friendly halogen-free flame-retardant and temperature-resistant materials are urgently needed

Abstract

The invention discloses a flame-retardant car roof material and a preparation method thereof. The flame-retardant car roof material is prepared by the following ingredients in parts by weight: 36-40 parts of polypropylene, 20-30 parts of trimethylol propane trimethyl acrylate, 20-30 parts of hydroxy propyl methyl cellulose, 15-20 parts of EPDM, 8-12 parts of polyvinyl alcohol, 3-5 parts of ammonium polyphosphate, 2-5 parts of 1,2-hydrindene, 2-3 parts of alundum powder and 2-5 parts of a flame retardant. The invention also provides a preparation method of the flame-retardant car roof material. The method mainly comprises the steps of placing a weighed raw material into a homogenizer to be uniformly mixed, feeding the mixed material into a double-screw extruder, cutting the mixed material through a screw, extruding and pelletizating.

Description

technical field [0001] The invention belongs to the field of automotive interior materials, in particular to a flame-retardant car roof material and a preparation method thereof. Background technique [0002] Thermoplastic polymer materials are commonly used in automotive interior materials. In the selection of automotive interior materials, it is necessary to consider electrical short circuits, engine failures, traffic accidents and other reasons that can easily cause fires. The performance of automotive interior materials is related to property and personnel. Safety is closely related, so the development of flame-retardant, cushioning interior materials is particularly important. [0003] The foamed rubber used as EPDM rubber has good heat resistance but insufficient flame retardancy, and epichlorohydrin rubber used as other foam rubber has good flame retardancy but insufficient heat resistance, making it There are many restrictions on the scope of use. At present, the e...
