Abstract

Disclosed fiber reinforced thermoplasticity plastic is prepared by mixing the following raw materials in parts by weight: 30-60 parts of bamboo fiber, 30-80 parts of thermoplastic plastic, 0.25-0.6 part of a coupling agent, 0.3-0.8 part of a cross-linking agent, and 0.5-1.5 parts of a lubricant. The obtained fiber reinforced thermoplasticity plastic possesses the characteristics of being high in strength, good in dispersibility, low in production cost, excellent in environment protection performance, and the like, is suitable for multiple production technologies such as injection molding, extrusion sheet material, tube material molding and the like, and is applicable to multiple fields of furniture, buildings, decoration and the like.

Description

technical field [0001] The invention relates to the technical field of material science, in particular to a bamboo fiber reinforced thermoplastic. Background technique [0002] Thermoplastics are the most widely used plastics. They are formulated with thermoplastic resin as the main component and various additives. Under certain temperature conditions, plastics can soften or melt into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repetition is only a physical change. The types of thermoplastics mainly include Polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. However, these products are all based on non-renewable resource petroleum, which consumes a lot of energy in the production process and has a serious impact on the environment. At the same time, the production cost is high, and it is not easy to decompose in the soil environment, and it is easy to cause "white polluti...
