Embodiment Construction

[0007] Put the chopped corn stems and roots into a dryer to dry, then put them into a pulverizer for crushing, the fineness of the crushing is 20-300 mesh, and then add the corn stems and roots powder into a high-speed mixer with additives and Plastic powder (among which additives include lubricants, plasticizers, anti-ultraviolet agents, antioxidants, fillers, reinforcing agents, flame retardants, antistatic agents, coupling agents, adhesives) mixed, sheared , shunting, and position exchange to achieve the mixing of different components, the homogenization of polymers with different molecular weights, and the homogenization of temperature, and then enter the mixing equipment for melting, and the formed corn stem root plastic composite material is extruded through the hole die, Then use a granulator to make particles of corn stem and root plastic composite materials; or extrude from a mixing device through a die, and then undergo quenching and solidification to make a profile o...

Abstract

The present invention relates to a corn stalk root plastics composite material. Its composition includes 49-79% of corn stalk root, 19-49% of thermoplastic plastics and 2%-4% of adjuvant. The described corn stalk root can be corn stalk and corn leaf or mixture of corn stalk, corn leaf, corn cob and corn root, and the described adjuvant contains one kind of the following components: lubricating agent, plasticizer, UV-ray-resisting agent, antioxidant, filling agent, reinforcing agent, fire-retardant, anti-static agent, coupling agent and binding agent or combination of several kinds of them. Its production method includes the following steps: cutting corn stalk and root, drying, pulverizing to 20-300 meshes, adding the corn stalk and root powder into high-speed mixer, mixing it with plastic powder, granules and adjuvant, homogenizing, then mixing them, extruding and granulating, cooling, solidifying and making them into the invented corn stalk root plastics composite material.

Description

technical field [0001] The invention relates to a composite material, in particular to a corn stem root plastic composite material. Background technique [0002] Corn is the main food crop in my country, with an output of 130 million tons, and the output of corn stems and roots is about 300 million tons (corn stems and roots include corn stalks, corn leaves, corn cobs, and corn roots), and more than 60% of them are Corn stems and roots are burned as waste, and some burning processes also cause pollution to 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 turn the waste corn stems and roots after harvesting corn into treasures and use them, compound them with thermoplastics to form corn stems and roots plastic composite materials, and make them suitable for life, construction, chemical industry, environmental protection, transportation, etc. Various produ...
