Abstract
The invention discloses a method for producing a wood-plastic material by processing rice straws, which relates to the technical field of production and process of the wood-plastic composite material. The method mainly comprises the following steps: firstly processing the rice straws into the rice straw powder, of which the fineness is 60-80 meshes and water content is 3-5%; mixing the following materials of 45-80% of rice straw powders, 21-30% of waste plastics, 8-17% of filing materials, 2-4% of heat stabilizer, 2-11% of lubricant and 4-16% of assistant, wherein the material mixing temperature is 120-150 DEG C; and prilling, extruding, modeling, sanding and knurling to obtain the wood-plastic product, wherein the prilling temperature is 175-215 DEG C, and the extruding temperature is 140-170 DEG C. The raw materials of the wood-plastic material can be easily obtained, so that the production cost is low; and the waste resources can be recycled and regenerated, so that the content of the wood fiber and the silica of the products are high, the impact strength is high and can reach 1.5 times that of the national standard, and the service life is long.
Description
Technical field:
The present invention relates to Wood plastic composite process for processing technical field, relate in particular to a kind of method of rice straw processing plastic-wood material.
Background technology:
Wood plastic composite possesses the advantage of vegetable fibre and plastics simultaneously; The scope of application is extensive; The use field that almost can contain all logs, plastics, plastic-steel, duraluminum and other similar matrix material has simultaneously also solved the regenerated using problem of plastics, wood industry waste resource.
Its principal feature is: raw material resourcesization, product plasticization, use environmental protectionization, cost economization, reclaimingization.
The earth of our existence has been gone through the development in forties00000000 years, has just brought up the environment of suitable biological existence.Since 10,000 years of the past, variation took place in the ecology of the earth, and nearly one over 100 years, particularly serious.A large amount of fellings of tropical rain forest and human high speed development have all caused the vicious cycle of natural ecological environment to atmosphere, soil, water quality etc.In order to safeguard the environment of earth long-term survival; We should will accomplish to meet the natural law from links such as Economic development, industry product and daily lifes, form good ecological chain, the earth of protecting us to depend on for existence. but human existence all needs resource with development; The thing that we will do is how to go rationally to utilize limited resources to satisfy the demand of human sustainable development; And mould wood is exactly to consider under the prerequisite of resources circulation, a kind of plasticity-matrix material of developing out, with culled wood, plastic waste as starting material; Utilize again, make new material.This material no matter from texture and feel, can substitute the function and the use range of natural timber and other composite woods through after regenerating.
In the prior art, moulding wood and be with low value biomass fibers such as sawdust, wood chip, bamboo bits, rice husk, wheat straw, soybean hulls, Pericarppium arachidis hypogaeae, bagasse, cotton stalks is main raw material, with a kind of matrix material of plastics synthetic.Though its wood fibre content and resistance to impact shock can be up to state standards, but still the space that has a certain upgrade, still be not very desirable work-ing life.
Summary of the invention:
The object of the invention is to overcome the defective of prior art, and the method for high, the excellent in cushion effect rice straw processing plastic-wood material of a kind of wood fibre content is provided.
For realizing the object of the invention, technical scheme realizes through following mode:
A kind of method of rice straw processing plastic-wood material is characterized in that: the main technique step comprises pulverizing, batch mixing, granulation, extrudes, moulding, sanding and embossing, and the material component and each component concentration that comprise in the said batch mixing step are:
Said rice straw powder is after fully being dried by rice straw, to carry out cutting and grinding, and then carry out pulverizing making, and the fineness of rice straw powder is 60～80 orders, moisture content 3～5%.
The temperature of said batch mixing is 120～150 ℃.
The temperature of said granulation is 175～215 ℃.
The said temperature of extruding is 140～170 ℃.
Raw material of the present invention is easy to get, and production cost is lower, can be with the waste resource reclaimingization, and product wood fibre and dioxide-containing silica are high, and be excellent in cushion effect, and can be up to state standards 1.5 times, long service life.
Embodiment:
For the present invention is elaborated, further specify below in conjunction with specific embodiment,
A kind of method of rice straw processing plastic-wood material; The main technique step comprises: after at first rice straw fully being dried; Carry out cutting and grinding; And then carry out pulverizingly, be processed into the rice straw powder of fineness 60～80 orders, moisture content 3～5%, then according to following mass percent batch mixing:
The temperature of batch mixing is 120～150 ℃, again through granulation, extrude, steps such as moulding, sanding and embossing, make and mould Wood products.Wherein the temperature of granulation is 175～215 ℃, and the temperature of extruding is 140～170 ℃.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets is merely preference of the present invention, is not used for limiting the present invention, under the prerequisite that does not break away from spirit and scope of the invention; The present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
