preparation example Construction

[0025] A preparation method of bamboo fiber powder, comprising the following steps:

[0026] After steaming the bamboo slices, crush them along the bamboo fiber growth direction without breaking the bamboo slice fibers to obtain bamboo filaments;

[0027] Drying the bamboo filaments, and irradiating them with a microwave with a power of 180-220W for 40-45 minutes to obtain semi-carbonized bamboo filaments;

[0028] After the semi-carbonized bamboo silk is ground into bamboo powder, it is irradiated with a microwave with a power of 12-14KW for 80-90s, and heated to obtain the bamboo fiber powder.

[0029] Remove bamboo green and bamboo yellow from bamboo, and cut into bamboo slices. Bamboo chip steaming can remove soluble organic matter in bamboo, and at the same time make the bamboo chip absorb enough water, which is convenient for subsequent crushing. The crushing direction is the growth direction of the bamboo fiber, so as to avoid the breakage of the bamboo fiber.

Abstract

The invention provides a bamboo fiber powder, a bamboo fiber composite board and a preparation method thereof, comprising the following steps: after cooking the bamboo chips, crushing them along the growth direction of the bamboo fibers without breaking the bamboo fibers to obtain bamboo filaments; The bamboo silk is dried, and irradiated under a microwave with a power of 180-220W for 40-45 minutes to obtain semi-carbonized bamboo silk; after the semi-carbonized bamboo silk is ground into bamboo powder, it is irradiated with a microwave with a power of 12-14KW for 80- 90s, heating to obtain the bamboo fiber powder. The above-mentioned bamboo fiber powder is combined with microwave and heating technology to form a large number of pores on the surface and inside of the bamboo powder, thereby increasing the surface area of ​​the bamboo fiber powder, which is better combined with other components in the bamboo fiber composite board such as resin and calcium powder .

Description

technical field [0001] The invention belongs to the technical field of plate processing, and in particular relates to bamboo fiber powder, bamboo fiber composite plate and a preparation method thereof. Background technique [0002] Bamboo has a short growth cycle and abundant resources, and bamboo products are widely used in daily life. Bamboo fiber composite board is a product that uses bamboo as raw material for deep processing. Among them, bamboo fiber extracted from bamboo is one of the important raw materials. Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability. The interface performance of bamboo fiber is poor, and it needs to be modified to better combine with resin and improve the strength of bamboo fiber and bamboo fiber composite board. Usual modification method all is to adopt chemical reagent to modify bamboo fiber, but this kind of mode does not match with the concept of green env...
