Embodiment Construction

[0007] Put the chopped wheat straw into the drying machine to dry, then put it into the pulverizer to pulverize, the pulverized fineness is 20-300 mesh, then add the wheat straw powder into the high-speed mixer with additives and plastic powder ( The additives include lubricants, plasticizers, anti-ultraviolet agents, antioxidants, fillers, reinforcing agents, flame retardants, antistatic agents, coupling agents, adhesives) mixed, sheared, shunted, positioned Exchange to achieve mixing of different components, homogenization of polymers with different molecular weights, and homogenization of temperature, and then enter the mixing equipment for melting, and the formed wheat straw plastic composite material is extruded through a hole die, and then made by a granulator Particles of wheat straw plastic composite materials; or extruded by mixing equipment through molds, quenched and solidified to make profiles of wheat straw plastic composite materials.

Abstract

The present invention relates to a wheat straw plastics composite material, and its composition includes 49%-79% of wheat straw, 19%-49% of thermo-plastic plastics and 2%-4% of adjuvant. The described wheat straw can be wheat straw and wheat straw leaf of fruiting body or their mixture, and the described adjuvant is one kind of the following components: lubricating agent, plasticizer, UV-ray-resisting agent, anti-oxidant, filling agent, reinforcing agent, fire-retardant, anti-static agent, coupling agent and binding agent. Its production method includes the following steps: cutting wheat straw, drying, pulverizing to 20-300 meshes, adding the wheat straw power into high-speed mixer, mixing it with adjuvant and plastic powder, homogenizing, further mixing, extruding, granulating, cooling, solidifying and making them into the invented wheat straw plastics composite material.

Description

technical field [0001] The invention relates to a composite material, in particular to a wheat straw plastic composite material. Background technique [0002] Wheat grain is the main food crop in my country. The output of wheat in China reaches 113 million tons, and the output of wheat straw reaches about 30 million tons (wheat straw includes wheat straw, wheat straw leaves, and seed shells), and more than 80% of wheat straw is used as waste Burning, and some burning processes also pollute the natural environment, and even cause traffic accidents and grounding of airline flights. Contents of the invention [0003] The purpose of the present invention is to use the waste wheat straw after harvesting wheat grains to turn waste into treasure, compound it with thermoplastic plastics to form wheat straw plastic composite materials, and make various types of plastic materials that can be applied to industries such as life, construction, chemical industry, environmental protection...
