Problems solved by technology

However, in the process of traditional production and industrial processing, the utilization rate of bamboo resources is lower than 40%, that is, more than 60% of bamboo resources become processing wastes such as bamboo joints, bamboo strips, bamboo boards, etc., which not only causes the shortage of bamboo resources in my country It is extremely wasteful, and the disposal of such a large amount of waste also greatly increases labor costs and environmental burdens

Embodiment 1

[0034] 1) The remaining twigs, leftovers, bamboo shavings and bamboo powder in the bamboo and wood processing process are crushed and ground to make 60-mesh fine powder;

[0035] 2) Mix 100kg of the fine powder obtained in step 1) with 2kg of corn flour and stir evenly, then add 2kg of warm water at 50°C and fully stir until it becomes a paste;

[0036] 3) The material obtained in step 2) is directly extruded into granules through an 80°C screw extruder, and the water content of the obtained granules is 9%.

[0037] The obtained granules are convenient for storage and transportation, and can be sold as raw materials for preparing bamboo tableware, bamboo cutting boards and bamboo furniture.

Embodiment 2

[0039] 1) The remaining twigs, leftovers, bamboo shavings and bamboo powder in the bamboo and wood processing process are crushed and ground to make 60-mesh fine powder;

[0040] 2) Add 100kg of the fine powder obtained in step 1) to 3kg of corn flour and stir evenly, then add 8kg of warm water at 40°C and fully stir until it becomes a paste;

[0041] 3) The material obtained in step 2) is directly extruded into granules through a 90°C screw extruder, and the water content of the obtained granules is 9%;

[0042] 4) Melt the granules obtained in step 3) with water to form a paste, add 3kg of glutinous rice flour and 5kg of resin glue, stir well, pour into a mold, and press at 80°C for 15 minutes to make the water content 8%. Bamboo cutting board.

[0043] The prepared bamboo cutting board is detected, and its formaldehyde emission is 8.6mg / kg, which is lower than the international standard of 15mg / kg; SO 2 The residual amount is below 100mg / kg, which is obviously lower than ...

Embodiment 3

[0045] 1) The remaining twigs, leftovers, bamboo shavings and bamboo powder in the bamboo and wood processing process are crushed and ground to make 80-mesh fine powder;

[0046] 2) Mix 100kg of the fine powder obtained in step 1) with 4kg of glutinous rice flour and mix evenly, then add 6kg of warm water at 45°C and fully stir until it becomes a paste;

[0047] 3) The material obtained in step 2) is extruded into granules through a screw extruder at 100°C, and the water content of the obtained granules is 9%.

[0048] The obtained granules are convenient for storage and transportation, and can be sold as raw materials for preparing bamboo tableware, bamboo cutting boards, bamboo furniture, bamboo floor wood and the like.

Abstract

The invention discloses a preparation method of a bamboo fiber material. The method comprises the following steps: crushing a raw material comprising brush woods, leftovers, bamboo shavings and bamboo powder residual in the bamboo wood processing process to form 60-100 mesh fine powder, adding other materials, stirring until uniformity, and extruding to prepare particles or carrying out compaction molding. The method fully utilizes the brush woods, leftovers, bamboo shavings and bamboo powder residual in the bamboo wood processing process, realizes reuse of a large amount of waste bamboo materials, and effectively mitigates the environment burden, and the prepared bamboo fiber material has the advantages of few harmful substances, good toughness and high safety, can be used to make bamboo tableware, bamboo chopping boards and even bamboo furniture and bamboo floor woods, can substantially improve the economic benefit of enterprises, and has good popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of bamboo product processing, and in particular relates to a preparation method of bamboo fiber material. Background technique [0002] my country is the country with the most abundant bamboo resources in the world, and its bamboo species, planting area and stock volume all rank first in the world. However, in the process of traditional production and industrial processing, the utilization rate of bamboo resources is lower than 40%, that is, more than 60% of bamboo resources become processing wastes such as bamboo joints, bamboo strips, bamboo boards, etc., which not only causes the shortage of bamboo resources in my country It is a great waste, and the disposal of such a large amount of waste also greatly increases labor costs and environmental burdens. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of bamboo fiber material, which can not only re...
