Abstract

The invention discloses a preparation method of a composite material with high wear resistance. The preparation method comprises the following steps: feeding weighed ABS, poly(p-phenylene terephthamide), epoxy resin and glass fibers to a dryer for drying; feeding dried ABS, poly(p-phenylene terephthamide) and epoxy resin to a mixer for mixing; adding a filler, a coupling agent, an anti-wear agent and an antioxidant to the mixer containing ABS, poly(p-phenylene terephthamide) and epoxy resin in sequence to obtain a mixture; adding the mixture to a hopper of a twin-screw extruder, performing melt blending by controlling screw speed at 280-420 r / min, temperature of each zone of the extruder at 215-235 DEG C and temperature of a head at 225-235 DEG C, and extruding a product from the head to obtain the composite material. The prepared composite material has higher wear resistance and better other mechanical properties and meets requirements of engineering materials; the preparation process is simple, easy to operate and contains a few procedures, manpower and material resources are reduced greatly, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of a high wear resistance composite material. Background technique [0002] With the continuous development of materials, materials are applied in different occasions. [0003] Some parts that are often in contact with each other are very easy to wear due to the contact surface, resulting in frequent replacement of parts, which is not only time-consuming and labor-intensive, but also causes great losses due to interruption. [0004] Among the existing polymer materials, there are materials with good strength, high rigidity, anti-corrosion and other excellent properties. However, in the existing material preparation methods, there is no good method to prepare high wear-resistant materials, which can meet the application, such as: axle sleeves or car seat covers. Contents of the invention [0005] In view of this, the present invention provides a ...
