Embodiment 1

[0039] First, modify the waste polyethylene; select 300 kg of waste polyethylene shredded raw materials after cleaning, waste rubber powder, such as waste car belts, etc., grind 40 kg of powder into about 100 mesh, 20 kg of butadiene rubber, and activate Put 40 kg of inorganic particles into the extruder and heat at 160°C, extrude and granulate. The activated inorganic particles are prepared from light calcium carbonate and titanate coupling agent.

[0040] Then the waste polypropylene is modified; choose 65 kilograms of waste polypropylene raw materials after cleaning, 10 kilograms of chlorinated polyethylene, 10 kilograms of waste rubber powder, 10 kilograms of scraps of EPDM rubber, 500 objects of waste ceramic fine powder 5 kg, put it into the extruder and heat it at 180°C, extrude and granulate.

[0041] Then modify the rice husk powder or wood powder; select 340 kg of dry 100-mesh rice husk powder or wood powder, 60 kg of chlorinated polyethylene, heat at 150-160 ° C, a...

Embodiment 2

[0046] Modification of waste polyethylene, waste polypropylene, rice husk powder or wood powder by the method and weight percentage described in Example 1. Then mix the modified granular waste polyethylene, waste polypropylene, rice husk powder or wood powder and grind it into a powder material with a fineness of 100 mesh to close to nanometer level with an ultrafine mill.

[0047] Then put 200 kg of the above-mentioned modified waste polyethylene, 200 kg of modified waste polypropylene, 500 kg of modified rice husk powder or wood powder, and 100 kg of additives into a mixer and stir evenly, then put them into the extruder to heat After mixing at 170°C, inject the extruded material into the mold and form it by a hydraulic press, hold the pressure for 3 to 10 minutes, cool it to 60°C with circulating water, and then open the mold and take out the finished product. The mold can be a mold for producing an automobile chassis or a mold for other products.

Abstract

The present invention relates to a production method of composite material, in particular, it is a method for producing composite material by utilizing high-molecular discards, such as waste polyethylene, waste polypropylene, waste rubber, wood flour and husk powder. Said method includes the following steps: making the above-mentioned waste and discarded materials respectively undergo the processes of chemical and physical treatment to make modification, using superfine mill to make the modified material undergo the process of superfine treatment to make its fineness up to above 100 meshes to approach to nano material, according to requirements, adding the materials of adjuvant according to different mixing ratio so as to regenerate a new composite material. The composite material can be used for making various members, can bumper, can chassis and others.

Description

Technical field: [0001] The invention relates to a method for producing composite materials, in particular to a method for producing composite materials by using polymer waste. Background technique: [0002] At present, discarded polyethylene, polypropylene, rubber, plastic and other products are difficult to decompose naturally in nature. These products can not be effectively reused, but also cause environmental pollution, destroy ecological balance, and cause waste of resources. . Methods for producing composite materials from waste have already emerged, and the composite materials produced by these methods are only used in the construction industry and have a narrow range of applications. And existing production composite material can't produce component such as automobile bumper, automobile chassis, belt conveyor roller. Invention content: [0003] The object of the present invention is to provide a kind of using polymer waste, such as waste polyethylene, waste polyp...
