Problems solved by technology

In the plant fiber products prepared by this method, the main raw material for supplying microbial nutrients in the degradation process is lignocellulose, which has a single component, which limits the decomposition of plant fiber products by microorganisms in the degradation process, so the degradation rate is slow, and generally requires It begins to degrade in 2 to 3 years

preparation example Construction

[0034] The present invention also provides a preparation method of plant fiber products, comprising:

[0035] 40wt% to 50wt% of plant fiber powder, 30wt% to 40wt% of soybean protein adhesive, 5wt% to 10wt% of cornstarch, 5wt% to 10wt% of glycerin, 4wt% to 7wt% of rice bran and 3wt% to 8wt% of water is mixed, heated and molded to obtain plant fiber products.

[0036] Plant fiber powder is the main raw material of the plant fiber product, preferably bamboo fiber powder. The content of the plant fiber powder is preferably 42wt%-48wt%, more preferably 43wt%-47wt%. The particle size of the plant fiber powder is preferably 50-80 mesh, more preferably 50-70 mesh.

[0037] Soybean protein adhesive has a bonding effect, which plays the role of bonding various components. The protein component in it can supply microbial protein and other nutrients during the degradation process of plant fiber products, thereby providing more sufficient nutrients for the growth and reproduction of micr...

Embodiment 1

[0050] 50 parts by weight of bamboo powder, 30 parts by weight of soybean protein adhesive, 5 parts by weight of cornstarch and 5 parts by weight of rice bran are fully stirred and mixed evenly in a high-speed mixer, then 5 parts by weight of glycerin and 5 parts by weight of water are added, and the stirring is continued. Adjust the mold temperature of the molding machine to 140°C and the molding pressure to 10Kg / cm 2 ;

[0051] According to the size of the mold, an appropriate amount of mixed raw materials is weighed and poured into the mold, the molding machine is started to heat and mold, and after about two minutes, the mold is demoulded to obtain a plant fiber product.

Embodiment 2

[0053] 45 parts by weight of bamboo powder, 35 parts by weight of soybean protein adhesive, 7 parts by weight of cornstarch, 1 part by weight of Guangdong Zhongshan Huamingtai Chemical Material Co., Ltd. are produced by the model of BS2818 ion modifier and 3 parts by weight of rice bran in Fully stir and mix evenly in a high-speed mixer, then add 5 parts by weight of glycerin and 4 parts by weight of water, continue to stir evenly, adjust the mold temperature of the molding machine to 130°C, and the molding pressure to 12Kg / cm 2 ;

[0054] According to the size of the mold, an appropriate amount of mixed raw materials is weighed and poured into the mold, the molding machine is started to heat and mold, and after about two minutes, the mold is demoulded to obtain a plant fiber product.

Abstract

The embodiment of the invention discloses a plant fiber material composite and a preparation method of a plant fiber product. The method comprises: 40wt% to 50wt% of plane fiber powder, 30wt% to 40wt% of soy protein adhesive, 5wt% to 10wt% of corn starch, 5wt% to 10wt% of glycerol, 4wt% to 7wt% of cavings and 3wt% to 8wt% of water are mixed and molded through heating and mould pressing to prepare the plant fiber product. The soy protein adhesive has the action of adhesion, and the protein component in the soy protein adhesive can supply rich nutrition components for microorganisms, and accelerates the decomposition of the plant fiber product by utilizing the microorganisms and the degradation of the plant fiber product in the degradation course of the plant fiber product. The experiment result indicates that the prepared plant fiber product has quicker degradation rate, starts to be degraded in 2 to 6 months, can be completely degraded in two years and has the advantages of no pollution and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of composite materials, and more specifically, relates to a plant fiber material composition and a preparation method of plant fiber products. Background technique [0002] With the improvement of people's living standards, the demand for minerals and natural resources is also increasing, exacerbating the shortage of various resources, and the cost continues to rise. In life, plastic products and paper products are widely used. However, due to the shortage of petroleum resources, the price of petroleum continues to rise, which leads to the continuous increase of the cost of plastics and brings great pollution to the environment. Therefore, people are looking for substitutes for plastic products. Paper products need to use paper as raw material, and the preparation of paper must cut down trees, which not only damages the natural resources of the ecological environment, but also produces a large amount of sew...
