Abstract

The invention provides a sisal hemp fiber and polypropylene fiber mixture interior ornament material of a vehicle. First, Sisal hemp is cut into sisal hemp fiber with 5 to 7 cm; second, the sisal hemp fiber is put into a stainless steel container and is mixed with sodium hydroxide solution to soak and stir for 1 hour; third, the sisal hemp fiber is cleaned with clear water for removing sodium hydroxide and then the sisal hemp fiber is put into hot water with 30 to 60 temperature so as to removing residual sodium hydroxide with constant temperature bath; fourth, the sisal hemp fiber is dried by a dryer; fifth, mixed liquid of methyl methacrylate of 0.5 to 1 percent blended with clear water every 100kg and nitric acid ene ammonium of 0.5 to 0.1 percent is used to soak for reaction; sixth, the sisal hemp fiber is dried after being cleaned with clear water; seventh, the sisal hemp fiber and polypropylene fiber are put on a wool comber for opening mixture; the sisal hemp fiber is within the range of 60 to 70 percent and the polypropylene fiber is within the range of 30 to 40 percent; eighth, the sisal hemp fiber and the polypropylene fiber mixture is carded to be a net by a carding machine; ninth, the sisal hemp fiber and the polypropylene fiber mixture is spread to be mixture material with 1500 g per square meter by a parallel net-spread machine; and tenth, the mixture material is molded into an interior ornament type part by a mould-pressing molding machine.

Description

technical field [0001] The invention relates to an automobile interior material, in particular to an automobile interior material mixed with sisal fiber and polypropylene fiber. Background technique [0002] Automotive interior moldings are usually made of polystyrene, polyvinyl chloride and other materials. This type of interior material has many defects such as poor heat resistance, unsatisfactory tensile and impact strength during use. Moreover, synthetic polymer materials such as polystyrene and polyvinyl chloride are difficult to degrade in nature, and discarded interior materials are bound to bring environmental pollution. Contents of the invention [0003] The object of the present invention is to provide an automobile interior material mixed with sisal fiber and polypropylene fiber, which has the characteristics of good stability, strong impact resistance, and environmental friendliness. [0004] The present invention comprises that the mixed material is mold...
