Problems solved by technology

[0003] The purpose of the present invention is to use the waste straw after rice harvesting to turn waste into treasure, and compound it with thermoplastic plastics to form a straw-plastic composite material, and make it into various types of straws that can be used in industries such as life, construction, chemical industry, environmental protection, and transportation. All kinds of products are a kind of material with excellent performance to replace wood, plastic and aluminum alloy, and at the same time solve the problem of pollution to the natural environment due to straw burning

Embodiment Construction

[0005] Put the chopped straw into the dryer for drying, then put it into the pulverizer for crushing, the fineness of the crushing is 20-300 mesh, then add the straw powder into the high-speed mixer with additives and plastic powder (Auxiliaries include lubricants, plasticizers, anti-ultraviolet agents, antioxidants, fillers, reinforcing agents, flame retardants, antistatic agents, coupling agents, adhesives) mixed by shearing, shunting, position 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 straw-plastic composite material is extruded through a hole die, and then made by a granulator Particles of straw-plastic composite materials; or extruded by mixing equipment through molds, quenched and solidified to make profiles of straw-plastic composite materials.

Abstract

The composite material consists of rice straw 49-79 wt%, thermoplastic plastic 19-49 wt% and assistant 2-4 wt%. The rice straw may be rice straw and / or husk; and the assistant may be one or several of lubricant, plasticizer, uvioresistant agent, antioxidant, stuffing, reinforcer, fire retardant, antistatic agent, coupling agent and adhesive. The production process of the composite material includes stoving and crushing rice straw into 20-300 mesh; mixing straw powder is plastic powder and assistant in a high speed mixer; extruding via mold hole; pelletizing in the pelletizing machine; fast cooling, curing, and making into shaped material.

Description

technical field [0001] The invention relates to a composite material, in particular to a straw-plastic composite material. Background technique [0002] Paddy is the most important food crop in my country. The annual planting area and output account for 29% and 44% of food crops respectively. The output of rice in my country reaches 200 million tons, and the output of rice straw reaches about 30 million (rice straw includes rice straw , rice leaves, rice husks), more than 80% of the straw is burned as waste, and some burning processes also cause pollution to the natural environment, and even cause traffic accidents and grounded airliners. Contents of the invention [0003] The purpose of the present invention is to use the waste straw after rice harvesting to turn waste into treasure, and compound it with thermoplastic plastics to form a straw-plastic composite material, and make it into various types of straws that can be used in industries such as life, construction, chem...
