Abstract
The invention discloses a wood plastic material of a special section for building doors/windows, which comprises the following components by weight percent: 20-45% of polyethylene agricultural film reclaimed material, 51-70% of crop straw powder, 0.2-2.0% of lubricating agent, 3-15% of coating agent, 1.0-8.0% of coupling agent, 1.0-5.0% of hygroscopic agent, 0.5-2.0% of anti-aging agent and 0.1-5.5% of other assistants. The wood plastic material of a special section for building doors/windows has fine comprehensive mechanical properties and favorable processability, the crop straw powder accounts for far higher than 50%, and the material can be produced into the special section for building doors/windows by fast extrusion. Besides, the product has the advantages of beautiful appearance, high strength, low cost, easy processing, no harm to human bodies and convenient production and procurement, has natural wood flavor, can be subjected to color matching as required, meets the requirements on environment friendliness and economy and raises the competitive position.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to a kind of building doors and windows special-purpose section Wood-plastic material.The invention still further relates to the method for making this building doors and windows special-purpose section Wood-plastic material.
Background technology
Sash stuff in the market is to adopt metal or timber to make mostly, and cost is higher, and uses Mineral resources in a large number or damage forest, and the consumption resource is more, and product life is also not long sometimes, very easily damages.
The country that has abroad, the wood plastic product more than 50% that the wood powder ratio accounts for overall proportion just can be as being that woodwork is sold society; Because wood powder and plastics are refuse reclamation all, so in raising people's quality of life and level, also be huge to the meaning of environment protection.
Wood-plastic material on the Chinese market is wood powder or xylon and the plastics compound that adopts log mostly at present, the lumbering deforestation there is certain pushing effect, because the strength of materials and processibility are bad, only only limit to extrude the product that some are simple relatively, intensity is not high, simultaneously again because the high enterprise of the bad processing charges that causes of processibility, thereby having to reduce as possible material cost, gone on the route of the vicious cycle competition of inferior quality low price, is huge to the damage of this industry.
Summary of the invention
The objective of the invention is to, provide a kind of can extruding fast to produce the building doors and windows special-purpose section and have the natural breath of timber, the building doors and windows special-purpose section Wood-plastic material that can match colors on request.
Technical scheme provided by the invention is as follows, forms agricultural polyethylene film reclaimed materials: 20-45%, agricultural crop straw powder: 51-70% by weight by following composition; Lubricant: 0.2-2.0%; Coating: 3-15%; Coupling agent: 1.0-8.0%; Moisture adsorbent: 1.0-5.0%; Anti-aging agent: 0.5-2.0%; Other auxiliary agents: 0.1-5.5%.
The preparation method of building doors and windows special-purpose section Wood-plastic material of the present invention, comprise the steps: earlier with polyethylene, agricultural crop straw powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 5 minutes, again through twin screw extruder mixingly under the screw combinations situation that certain intensity is sheared extrude, pelletizing, make building doors and windows special-purpose section Wood-plastic material through screening and dewatering.
On the building doors and windows special-purpose section Wood-plastic material of the present invention,, processibility good basis good at comprehensive mechanical performance, agricultural crop straw powder proportion is far above 50%, can extrude production building doors and windows special-purpose section fast with material of the present invention, and product appearance is attractive in appearance, has the natural breath of timber, the intensity height, can match colors on request, simultaneously with low cost, process easy, meet environmental protection, economic characteristics, harmless, production procurement is convenient, has improved competitive power.
Embodiment
Below be the most preferred embodiment of building doors and windows special-purpose section Wood-plastic material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of building doors and windows special-purpose section Wood-plastic material is provided, and is made up of by weight following composition: the agricultural polyethylene film reclaimed materials: 27.5%, and agricultural crop straw powder: 57%; Lubricant: 1.0%; Coating: 3.0%; Coupling agent: 5.0%; Moisture adsorbent: 3.0%; Anti-aging agent: 2.0%; Other auxiliary agents: 1.5%.
Concrete steps of the present invention are: earlier will be earlier with polyethylene, agricultural crop straw powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 5 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 32 length-to-diameter ratios, the combination of prescribed strength shear screw, and setting is not higher than 300 rev/mins rotating speed; Adopt die face ring cutting mode, promptly make building doors and windows special-purpose section Wood-plastic material through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
