One utilizes straw waste material plastic compression composite material
Technical field
Present invention classification belongs to operation B27, relates to one and utilizes straw waste material plastic compression to be combined
The technical field of section bar.
Background technology
The physical and mental health of the very important people of economic development.Healthy necessary protecting ecology ring again
Border.Burning of plant straws contaminated air attracts great attention.Someone utilizes straw to send out
Electricity;Someone is for pressed sheet.Then, seasonal raw material supply problem is occurred in that;Raw material
Stacking problem;Board quality problem;The environmental issue etc. of sheet material.For solving foregoing problems,
The most in succession occur in that some patented technologies: 201010165207 " a kind of corn stalk moulded board is raw
Product method and processing technology thereof " it is disclosed that according to raw material: adhesive 70%-80%, stirring
10-15 minute paving mould, with temperature 135-170 DEG C, pressure 2.0-3.5mpa, time
25-40s/mm is hot-forming.200910010699 " Sunflower Pole laminated boards ... .. " are disclosed that
Make after amassing sheet group hot-forming of substrate.201010272475 " a kind of plant straw board and
Its manufacture method ", it is made up of straw, magnesium oxide, magnesium chloride, maturing promotor agent.
These patented technologies are to seasonal raw material supply problem;The stacking problem of raw material;Board quality
Problem;The environmental issue etc. of sheet material, the most thoroughly solves.Particularly being harmful to into of binding agent
Divide and the most do not cause enough attention.
Summary of the invention
It is an object of the invention to utilize various plants straw waste material is primary raw material, gathers with high pressure
Ethylene is binding agent, adds the preparation rational mixture such as fire retardant, it is provided that one meet environmental requirement,
It is suitable for industrial utilizing straw waste material plastic compression composite material.
The present invention takes techniques below scheme:
With plants such as Semen Maydis, Helianthi, Cotton Gossypii, rice husk, wheat straw, Cortex beans, sawdust, wood flours
The wooden wastes such as straw are A raw material, include with polyethylene from high pressure process: polyethylene, polypropylene, poly-
The waste or used plastics such as vinyl chloride are B raw material, are separately dried the fiber being crushed to 100-200 mesh
Shape, takes A raw material and B raw material by weight mixture, add fire retardant, antifungus agent, coupling agent,
Pelletize after plasticizer, color masterbatch, insecticide, enter screw machine heat 120-170 DEG C, extrude into
Mould pressurizes, and prepares variously-shaped section bar.
By weight by A raw material 65%, B raw material 42%, add the additive compound of 3%, bag
Include: carry out mixture after fire retardant, antifungus agent, coupling agent, plasticizer, color masterbatch, insecticide and make
Grain, heating to extrude is forced into finished product into mould.
Prepared variously-shaped section bar, preferably profile material;
Prepared variously-shaped section bar, preferably frame section;
Prepared variously-shaped section bar, preferably column section;
Prepared variously-shaped section bar, the most ring-like material;
Prepared variously-shaped section bar, preferably profile shapes;
Due to, have employed above technical scheme, the present invention has that to make full use of straw etc. useless
Material, beneficially environmental conservation;Product is corrosion-resistant, do not damage by worms, durable, life-span length, outward appearance beautiful
Beautiful;There is excellent physical property, do not split, the most bent, can cut, can dig, can follow closely, can bore, can glue
Connect;Product specification shape can be adjusted flexibly change as required;Degradable, recoverable;
The feature such as aboundresources, low cost.It is applicable to various building and ornament materials.

Detailed description of the invention
Batch mixer, conveyer, drying tower, moulding press is utilized to form production line.According to product
Specification shape prepares template, frame-type, column type, the mould of the shape such as ring-like, special-shaped respectively.
In field, the edge of a field, scrap heap, preposition pulverizer.It is main with wooden waste as raw material,
Including: the plants such as Semen Maydis, Helianthi, Cotton Gossypii, rice husk, wheat straw, Cortex beans, sawdust, wood flour
Straw etc., drying and crushing to 100-200 mesh, form fibrous powder composition A raw material.
With waste and old thermoplastics such as polyethylene from high pressure processes, including: polyethylene, polypropylene, polychlorostyrene
Ethylene etc., drying and crushing to 100-200 mesh, form fibrous powder composition B raw material.
By weight being 65% by taken A raw material, taking B raw material is 42% to carry out mixture, adds
Pelletize after the fire retardant of 3%, antifungus agent, coupling agent, plasticizer, color masterbatch, insecticide, enters
Screw machine heats 120-170 DEG C, extrudes and is forced into finished product into mould.
Plastic compression composite material can make profile material, frame section, column section, ring-like material, profile shapes
Etc. variously-shaped building and ornament materials.The key technical indexes of various section bars is: density kg/
m20.4-0.95;Water content≤3%;Water absorption≤4%;Rockwell hardness HRR >=60%;Bending is strong
Degree mpa >=12%;Hot strength mpa >=12%;Vertical combustion fv-0 level;Horizontal firing 1 grade;
The N of resistance to nail pull strength >=12%.
