Preparation method of ecological bamboo-wood profile

Abstract

The invention provides a preparation method of an ecological bamboo-wood profile. The preparation method comprises the following steps: weighing the raw materials and putting into a mixer, adding an appropriate amount of water, a foaming agent, a regulator, a toner, a plasticizer and a coupling agent, and mixing evenly; next, putting all the materials into a high-temperature furnace, heating to the range of 200 to 260 DEG C and maintaining for 1-2 hours; injecting the heated mixture into a die, performing die-casting molding, and performing cooling, blow-drying, laminating, sizing, cutting and baling on the molded slab. The ecological bamboo-wood profile has the advantages of low carbon and environmental friendliness, non-toxicity and tastelessness, fire protection, water prevention, insect prevention, mildew prevention, protection against termites, acid-base resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of profiles, in particular to a method for preparing ecological bamboo and wood profiles. Background technique [0002] There are three methods for the processing of existing bamboo and wood profiles. One is to process bamboo and wood into fibers or powders, mix them with adhesives, and then mold them, extrude them, and hot press them. The disadvantage is that bamboo and wood are used as filling materials. The products lose the original characteristics of bamboo and wood, and the bending resistance and impact resistance are greatly reduced; the second is that bamboo and wood are processed into blocks or sheets, and then glued and pressed into plates and profiles, such as multi-layer boards, finger-jointed boards, Stress-free boards, etc., the products produced by this method continue the performance defects of bamboo and wood, such as moisture absorption cracking, corrosion deformation, insects, and flammabi...

[0002] There are three methods for the processing of existing bamboo and wood profiles.

The disadvantage is that bamboo and wood are used as filling materials. The products lose the original characteristics of bamboo and wood, and the bending resistance and impact resistance are greatly reduced; the second is that bamboo and wood are processed into blocks or sheets, which are glued and pressed into plates and profiles, such as multi-layer boards, finger-jointed boards, Stress-free boards, etc. The products produced by this method continue the performance defects of bamboo and wood, such as moisture absorption cracking, corrosion deformation, insects, flammability, etc.

This method modifies and plasticizes bamboo and wood, improves its strength and anticorrosion, but cannot produce profiles
