Abstract
The invention relates to a plant straw and biogum compound material and a preparation method thereof. The compound material is prepared from the following components in percentage by weight: 80% of plant straws and 20% of biogum, totaling 100%, wherein a water-proofing agent accounts for 2wt% of the plant straws and the biogum, the plant straws are wheat straws, the biogum is plant albumen glue and the water-proofing agent is glycerinum. The preparation method comprises the following steps: smashing and drying the plant straws; drying the biogum and mixing with the water-proofing agent; paving; carrying out compression molding and forming; cooling and forming to obtain the compound material in a certain specification. Meanwhile, the prepared compound material has an appearance of a wooden product and the processing characteristic of a wood-plastic compound material, and is wide in range of application.
Description
Technical field
The present invention relates to a kind of biomass composite of preparing with wheat straw fibre and vegetable-protein glue, relate in particular to a kind of straw and Biocomposite material and preparation method thereof, belong to manufacture technology of composite material field.
Background technology
Biomass composite is a kind of novel material, have can be degradable feature, pollution-free, be a kind of novel environmental friendly materials, receive increasing concern.
China's Forest Resources insufficient total amount, and rice and wheat straw annual production is about 1,400,000,000 tons.Wheat straw fibre reinforced composite is involved in, but mainly concentrates on the matrix material of Wheat Straw and plastics, and the matrix material that the xanthan gum vegetable-protein glue of take is matrix is rarely seen report also.The waste combustion of farm crop is a large root that causes environmental pollution, and vegetable-protein glue is pure natural, does not add any chemical reagent, therefore with matrix material prepared by Wheat Straw and vegetable-protein glue, has important economic benefit and environment protection significance.
Summary of the invention
The object of this invention is to provide a kind of Wheat Straw biomass composite, solved the environmental pollution that a large amount of wastes that straw underutilization causes and burning cause, and the problem of natural degradation completely of common wood-plastic composite; The preparation method of above-mentioned matrix material is provided simultaneously, solves manufacturing process difficulty large, the problem that production cost is high.
Technical scheme of the present invention is, a kind of biomass composite, by Wheat Straw, vegetable-protein glue, water-resisting agent, formed, according to weight percent, Wheat Straw is 80%, vegetable-protein glue is 20%, and Wheat Straw and vegetable-protein gummed count 100%, and water-resisting agent is 2% of Wheat Straw and vegetable-protein glue gross weight; Water-resisting agent is selected glycerine.
A kind of straw and Biocomposite material and preparation method thereof are to implement according to following steps:
Step 1: by Wheat Straw sorting and impurity elimination, the fiber that to shatter to length be 10-20mm, then dry for standby; By the vegetable-protein glue dry for standby of buying;
Step 2: weighing wheat straw fibre according to weight percent is 80%, and vegetable-protein glue is 20%, adding up to weight percent is 100%, weighing in addition additive is 2% of Wheat Straw and vegetable-protein glue gross weight again;
Step 3: three kinds of material mixing that step 2 is weighed, stir 10min;
Step 4: the mixing material that step 3 is obtained is mated formation in 100 * 120 mould, with the vulcanizing press compaction mold under normal temperature, then continues the mixing material of mating formation, until all material is put in mould;
Step 5: the pressure of vulcanizing press is adjusted to 6Mpa, and temperature is adjusted to 170 ℃, treats that temperature reaches design temperature, the mould that material is housed can be put into vulcanizing press, and mold closing, and clamp time is 20min;
Step 6: reach the clamp time of setting, vulcanizing press die sinking, mold removal, normal temperature is cooling, takes out the material pressing.
The invention has the beneficial effects as follows, with Wheat Straw, replace timber, with xanthan gum, replace plastics; be conducive to save the protection of timber resources and environment, solved Wheat Straw and burned the problem to the pollution of atmosphere and plastic pollution environment, described preparation method; simplify manufacturing process, reduced production cost.
