Abstract
The invention discloses a fence wood-plastic material which comprises the following components in percentage by weight: 20-45% of polyethylene agricultural film reclaimed material, 51-70% of crop straw powder, 0.2-2.0% of a lubricating agent, 3-15% of a covered agent, 1.0-8.0% of a coupling agent, 1.0-5.0% of a hygroscopic agent, 0.5-2.0% of an age resister, 0.1-10.0% of an antistatic agent and 0.1-5.5% of other additives. According to the invention, on the basis of good comprehensive mechanical property and excellent machinability, the proportion of the crop straw powder is far more than 50%, and the fence wood-plastic material can be used for producing a fence sectional material rapidly; in addition, the products are attractive in appearance, the fence wood-plastic material has the natural smell of timber, is high in strength, can be coated with different colors as required, is greatly prolonged in service life in a relative manner, meets the environmentally-friendly and economical characteristics, is harmless to human bodies and convenient to produce and purchase, and improves the competitive power.
Description
Technical field
The present invention relates to a kind of matrix material, more particularly, relate to a kind of fence Wood-plastic material.The invention still further relates to the method for making this fence Wood-plastic material.
Background technology
Fence material is in the market to adopt metal or timber to make mostly, and cost is higher, and uses in a large number Mineral resources or damage forest, and consumption resource is more, and product life is also not long sometimes, very easily damages.
The country having abroad, more than 50% wood plastic product that wood powder ratio accounts for overall proportion just can be as being that woodwork is sold society; Because wood powder and plastics are all refuse reclamations, so in improving people's quality of life and level, be also huge to the meaning of environment protection.
At present the Wood-plastic material in Chinese market is to adopt the wood powder of log or xylon and plastics compound mostly, lumbering deforestation is had to certain pushing effect, and, due to the strength of materials and processibility bad, only only limit to extrude the product that some are relatively simple, intensity is not high, the processing charges causing because processibility is bad again high enterprise simultaneously, thus have to reduce as possible material cost, the route of having gone on the vicious cycle competition of inferior quality low price is huge to the damage of this industry.
Summary of the invention
The object of the invention is to, provide one fence Wood-plastic material fast, and product appearance is attractive in appearance, have the natural breath of timber, intensity is high, can match colors on request, does not worry the fence Wood-plastic material of the problem such as distortion due to immersion.
To achieve these goals, technical scheme provided by the invention is as follows: it is made up of by weight following composition, agricultural polyethylene film reclaimed materials: 20-45%, crop stalk powder: 51-70%; 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%; Antistatic agent: 0.1-10.0%; Other auxiliary agents: 0.1-5.5%.
The preparation method of fence Wood-plastic material of the present invention, after comprising the steps: first polyethylene, crop stalk powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, antistatic agent, other auxiliary agents proportionally to be weighed in mixer low speed mixing 5 minutes, mixing extrusion, pelletizing in the screw combinations situation of shearing at some strength through twin screw extruder again, make fence Wood-plastic material through screening and dewatering.
Fence Wood-plastic material of the present invention is good at comprehensive mechanical performance, on the good basis of processibility, crop stalk powder proportion is far above 50%, can extrude fast fence special-purpose section with material of the present invention, and product appearance is attractive in appearance, there is the natural breath of timber, intensity is high, can match colors on request, do not worry the problem such as distortion due to immersion, relatively significantly extend work-ing life, can antimildew and antibacterial, can prevent dust absorption, simultaneously with low cost, process easy, meet environmental protection, economic characteristics, harmless, production procurement is convenient, improve competitive power.
Embodiment
Be below the most preferred embodiment of fence Wood-plastic material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment mono-, provides a kind of fence Wood-plastic material, is made up of by weight: agricultural polyethylene film reclaimed materials following composition: 22.5%, and crop stalk powder: 57%; Lubricant: 1.0%; Coating: 3.0%; Coupling agent: 5.0%; Moisture adsorbent: 3.0%; Anti-aging agent: 2.0%; Antistatic agent: 5.0%; Other auxiliary agents: 1.5%.
After first will be first polyethylene, crop stalk powder, lubricant, coating, coupling agent, moisture adsorbent, anti-aging agent, antistatic agent, other auxiliary agents proportionally being weighed in mixer low speed mixing 5 minutes, mixer adopts low speed mixing, paddle should be less than 0.5 centimetre with barrel gap, supplementary material mixed effect should visual various particles and powder substantially even, there is no obvious agglomerate or gather; Twin screw extruder uses 32 length-to-diameter ratios, and the combination of prescribed strength shear screw, arranges certain rotating speed; Adopt die face ring cutting mode, make fence Wood-plastic material through screening and dewatering.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in 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.
