Embodiment 1

[0035] A self-cleaning environment-friendly bamboo particle board, the preparation method is as follows:

[0036] 1. Preparation of bamboo scraps:

[0037] Prepare and screen qualified bamboo scraps, control the average thickness ≤ 0.3mm, length ≤ 10mm, screening value ≤ 4, moisture content 4%;

[0038] 2. Wood fuel ethanol residue preparation:

[0039] The residue of wood fuel ethanol is ground, so that the particle size is controlled below 80 mesh, and the moisture content is controlled below 3%;

[0040] 3. Raw material activation:

[0041]The ratio of each raw material is shown in the table below. According to the plank specification and set density and the ratio calculation of each raw material, weigh the quality of the bamboo scraps, add wood fuel ethanol residue according to 10% of the absolute dry mass of the bamboo scraps, and mix well to make it evenly mixed. Weigh the laccase solution according to 8% of the absolute dry mass of the bamboo scraps, prepare a disod...

Embodiment 2

[0051] 1. Preparation of bamboo scraps:

[0052] Prepare and screen qualified bamboo scraps, control the average thickness ≤ 0.3mm, length ≤ 10mm, screening value ≤ 4, moisture content 3%;

[0053] 2. Wood fuel ethanol residue preparation:

[0054] The residue of wood fuel ethanol is ground, so that the particle size is controlled below 80 mesh, and the moisture content is controlled below 3%;

[0055] 3. Raw material activation:

[0056] The ratio of each raw material is shown in the table below. According to the plank specification and set density and the ratio calculation of each raw material, weigh the quality of the bamboo scraps, add wood fuel ethanol residue according to 15% of the absolute dry mass of the bamboo scraps, and mix thoroughly to make it evenly mixed. Weigh the laccase solution according to 10% of the absolute dry mass of the bamboo scraps, prepare a disodium hydrogen phosphate-citric acid buffer solution with a pH of 4, and mix the two according to a ma...

Abstract

The invention discloses a self-cleaning environment-friendly bamboo particle board. The self-cleaning environment-friendly bamboo particle board comprises, by weight, 100 parts of bamboo particles, 10-15 parts of additives, 8-10 parts of activators, 0-5 parts of adhesive, 0.5-1.0 part of waterproof agents, 0.5-10 parts of adsorbents and 0.2-0.5 part of cleaning agents. The invention further discloses a method for manufacturing the bamboo particle board. The self-cleaning environment-friendly bamboo particle board and the method have the advantages that the particle board is made of waste ethanol residues of wood fuel, the absorbents, the cleaning agents, the waterproof agents and the like, the performance of the manufactured particle board can reach national standards, usage of the traditional adhesive can be prevented or reduced, and accordingly formaldehyde emission of the particle board can be greatly reduced; indoor pollution gas can be effectively absorbed by the manufactured particle board with the adsorbents, self-cleaning effects can be realized by the aid of the cleaning agents on the surfaces of the self-cleaning environment-friendly bamboo particle board, and accordingly the self-cleaning environment-friendly bamboo particle board is suitable for building decoration.

Description

technical field [0001] The invention belongs to the field of artificial board manufacture, and in particular relates to a self-cleaning and environment-friendly bamboo particle board, and also relates to a preparation method of the bamboo particle board. Background technique [0002] A large amount of processing residues will be produced in the process of bamboo processing. According to statistics, the weight utilization rate of bamboo in the production of bamboo flooring, bamboo plywood, bamboo mat and bamboo daily necessities is less than 40%, and more than 60% of the bamboo is in the process of processing. Turned into processing residues, most enterprises now use this as fuel, and some small processing sites are discarded, which is a serious waste of resources and affects the environment. It is an effective means to realize the comprehensive utilization of bamboo resources by using bamboo processing residues to manufacture bamboo particle boards. However, at present, mor...
