Problems solved by technology

This method improves the utilization rate of bamboo, and the stability of the profile is good, but there are following defects: 1) the raw material is generally all bamboo, and the material is too single, and the raw material supply is relatively tight; 2) when moso bamboo is made into bamboo silk, a large amount of bamboo will be produced The waste materials, including dust, particles, fragments and broken wires, reduce the utilization rate of raw materials; 3) the bamboo fiber structure is damaged to a large extent by the wire drawing method, and a large amount of glue is used in the reorganization process. The cost is high and the density (specific gravity) of the profile is increased
In addition, wood flooring and bamboo flooring are flammable materials. There is a big safety hazard in the processed products of bamboo and wood boards, which is that they are not fireproof and flammable, especially bamboo and wood flooring for household use. Therefore, with the enhancement of people's safety awareness, there is a Bamboo and wood panels with flame retardant function are more and more popular

Embodiment 1

[0028] A kind of fire-retardant bamboo-wood board production process method, comprises the following steps:

[0029] S1. Material selection: Bamboo can be selected from moso bamboo, miscellaneous bamboo, small-caliber bamboo or bamboo scraps after processing, and wood can be selected from poplar, willow or wood scraps after processing;

[0030] S2. Drying: first put the above raw materials in a natural drying place, and when they are air-dried to a moisture content of 30%, they are sent to a drying kiln for forced drying. The humidity in the drying kiln is controlled at 60% to 70%, and the time is 6 to 8 days. , control the temperature on the first day at 55°C to 60°C, and maintain a daily heating rate of 8°C until the temperature reaches 100°C, reducing the moisture content to 7% to 9%;

[0031] S3, rolling: the bamboo after the step (2) is degreened, the wood is peeled, and mechanically rolled into bamboo and wood blanks;

[0032] S4, drying again: putting the bamboo and wo...

Abstract

The invention discloses a manufacturing process method of a flame-retardant bamboo board, and relates to the technical field of bamboo material machining. Bamboo and boards are adopted as main raw materials of the flame-retardant bamboo board. The method comprises the following steps of 1, material selecting, 2, drying, 3, grinding, 4, secondary drying, 5, maintaining and 6, flame-retardant paint smearing. The bamboo and the boards are organically combined, the situation that adopted materials are too single is avoided, the bottleneck problem of existing raw materials is effectively solved, the inherent fiber structure of the raw materials is not destroyed basically, and the amount of glue adopted between the materials is lowered. In addition, flame-retardant paint is smeared to the surface of the bamboo board, the good flame retarding function can be achieved well, the fire resistance of bamboo and board machining pieces is improved, and the safety of the boards is improved.

Description

technical field [0001] The invention relates to the technical field of processing bamboo and wood materials, in particular to a method for manufacturing flame-retardant bamboo and wood boards. Background technique [0002] With the rapid development of my country's economy, the contradiction between supply and demand of timber has become increasingly prominent, especially the scarcity of large-scale and high-quality timber resources. At present, the raw materials for the production of wood-based panels and other wood products are mainly fast-growing industrial materials, which are loose, low-density, and low-strength. Bamboo has fast growth speed, strong reproductive ability, short cycle, high output, rich resources, and bamboo has strong longitudinal toughness, high hardness, and bending strength. Therefore, replacing wood with bamboo is an important measure to alleviate the contradiction between supply and demand of wood. It is also a high-quality alternative raw material...
