preparation example Construction

[0050] First aspect of the present invention provides a kind of preparation method of bamboo-based fiber composite material, described bamboo-based fiber composite material comprises a plurality of bamboo fiberized veneers, and it comprises the following steps:

[0051] Rolling and impregnating the bamboo fiberized veneer with an adhesive to obtain an impregnated product;

[0052] drying the impregnated product to obtain a dried product;

[0053] After sewing the dried product, at least a first bamboo-based material and a second bamboo-based material are obtained;

[0054] Assembling the first bamboo-based material and the second bamboo-based material to obtain a molded body;

[0055] Carrying out hot pressing to described molded body, obtains the blank of bamboo-based fiber composite material;

[0056] The bamboo-based fiber composite material blank is subjected to functional post-treatment to obtain the bamboo-based fiber composite material.

[0057]

[0058] The bamboo...

Embodiment 1

[0103] The bamboo is decomposed into a bamboo fiberized veneer, the width of the bamboo fiberized veneer is 10 cm, and the moisture content is 35%. Then, the fibrous veneer is rolled and compacted with an adhesive, then immersed in the adhesive, and then rolled to obtain an impregnated product. Among them, the rolling pressure is 20MPa. The adhesive is an aqueous solution of water-soluble impregnated phenolic resin, wherein the mass concentration of the water-soluble impregnated phenolic resin is 30%; meter) accounts for 15% of the mass content of the impregnated product after rolling.

[0104] Then, the impregnated product was dried with a mesh belt dryer at a drying temperature of 70° C. and a drying time of 80 min to obtain a dried product. After drying, the moisture content of the dried product was 12%.

[0105] The dried products are arranged in parallel and then subjected to whole-sheet sewing processing to obtain bamboo-based materials. Wherein, in the sewing proces...

Embodiment 2

[0110] The bamboo is decomposed into bamboo fiberized veneer, the width of the bamboo fiberized veneer is 10cm, and the moisture content is 35%, and then the fibrous veneer is rolled with an adhesive and then immersed in the adhesive, Then rolling is carried out to obtain the impregnated product. Among them, the rolling pressure is 15MPa. The adhesive is an aqueous solution of water-soluble impregnated phenolic resin, wherein the mass concentration of the water-soluble impregnated phenolic resin in the adhesive is 25%, after rolling, the moisture content of the impregnated product is 24.30%, and the content of the water-soluble impregnated phenolic resin ( 100%) accounts for 15% of the content of the bamboo-based material after rolling. Then, the impregnated product was dried with a mesh belt dryer at a drying temperature of 70° C. and a drying time of 60 min to obtain a dried product. After drying, the moisture content of the dried product was 12%.

Abstract

The invention relates to a bamboo-based fiber composite material and a preparation method thereof. The preparation method comprises the following steps that an adhesive is used for rolling and dippinga bamboo fiberized veneer, and a dipped product is obtained; the dipped product is dried to obtain a dried product; after the dried product is sewn, a first bamboo-based material and a second bamboo-based material are at least obtained; the first bamboo-based material and the second bamboo-based material are assembled to obtain a formed body; hot pressing is carried out on the formed body to obtain a bamboo-based fiber composite material blank; and functional post-treatment is carried out on the bamboo-based fiber composite material blank to obtain the bamboo-based fiber composite material. The preparation method of the bamboo-based fiber composite material is simple and easy to implement, raw materials are easy to obtain, continuous forming and manufacturing can be achieved, and the production efficiency is high.

Description

technical field [0001] The invention relates to a bamboo-based fiber composite material and a preparation method thereof, in particular to a continuous molding manufacturing method of the bamboo-based fiber composite material, which belongs to the field of wood materials. Background technique [0002] my country is the world's largest owner of bamboo resources and the world's largest producer of bamboo products. At present, my country's bamboo industry production scale and technical level rank among the top in the world. As people's awareness of environmental protection is getting stronger and stronger, bamboo has been recognized by the world as an environmentally friendly material with sustainable development characteristics, so the bamboo industry has developed rapidly in our country this year. [0003] Bamboo-based fiber composite material is a new type of natural polymer composite material made of my country's rich bamboo resources as raw materials through directional re...
