Embodiment Construction

[0007] Dry the chopped reeds in a dryer, then put them into a pulverizer for crushing, the fineness of the crushing is 20-300 mesh, and then add the reed powder into the high-speed mixer with plastic powder and additives (Auxiliaries containing lubricants, plasticizers, anti-ultraviolet agents, antioxidants, fillers, reinforcing agents, flame retardants, antistatic agents, compatibilizers, coupling agents, adhesives) mixed with fillers, After shearing, shunting, and position exchange, the mixing of different components, the homogenization of polymers with different molecular weights, and the homogenization of temperature are achieved, and then melted in the mixing equipment, and the formed reed plastic composite material is extruded through a hole die. , and then made into reed plastic composite material particles by a granulator; or extruded by a mixing equipment through a mold, quenched and solidified to make reed plastic composite material profiles.

Abstract

The present invention relates to composite reed-plastic material comprising reed 44-70 wt%, thermoplastic plastic 18-44 wt%, assistant 6-8 wt% and stuffing 2-4 wt%. The said assistant includes one of the following components or their composition: lubricant, plasticizer, ultraviolet resisting agent, antioxidant, stuffing, reinforcer, fire retardant, antistatic agent, compatilizer, couplant and adhesive. The stuffing is powdered mineral(s). The production process includes cutting, stoving and crushing reed to form 20-300 mesh powder, mixing reed powder with other components, mixing in mixing apparatus, extruding through hole die, pelletizing in a pelletizer, quenching and curing to form the section of the composite material.

Description

technical field [0001] The invention relates to a composite material, in particular to a reed plastic composite material. Background technique [0002] Phragmites reed, also known as reed, is a perennial herb that mostly grows near water, with large ears growing on the top. The growing area of ​​reeds in our country is relatively large, but the price is very low. At present, the price of reeds per mu is only about 20 yuan, and more than 50% of them are burned as fuel, which is a great waste of resources and causes environmental damage pollute. Contents of the invention [0003] The purpose of the present invention is to turn the discarded reeds into treasures and make use of them. The reeds that have been used can be used to increase the value of use, and compounded with thermoplastics to form reed-plastic composite materials, which can be used in industries such as life, construction, chemical industry, environmental protection, and transportation. It is a material with...
