Manufacturing method capable of inhibiting water encounter swelling of bamboo products

Abstract

The invention discloses a manufacturing method capable of inhibiting water encounter swelling of bamboo products. The manufacturing method comprises following steps: chitosan and water are mixed, dried bamboo strips are added, and an obtained mixture is allowed to high temperature standing so as to obtain a first material; urea, calcium lignin sulphonate, and cluster bean are uniformly mixed, andare subjected to aging and uniform grinding, glycerol, epoxy resin, and water are added for stirring, phosphoric acid is added for uniform mixing, filtering is carried out, vacuum drying is carried out until the weight of an obtained material is constant, and then crushing is carried out so as to obtain a second material; the second material, honeysuckle flower powder, a dispersant, and a thickening agent are added into a nanometer polyurethane emulsion for stirring, water, a film forming auxiliary agent, epoxy soybean oil, 3-iodo-2-propynylbutylcarbamate, a wetting agent, and a defoaming agent are added for uniform stirring and filtering so as to obtain a third material; the first material is dried, is subjected to carbonization treatment in a carbide furnace, is filtered, is immersed ina mixed oil, is taken out from the mixed oil, is dried, is coated with the third material, and is subjected to solidifying, drying, and braiding so as to obtain bamboo products.

Description

technical field [0001] The invention relates to the technical field of bamboo products, in particular to a production method for preventing bamboo products from swelling when encountering water. Background technique [0002] Bamboo has excellent toughness. A hurricane can easily blow off a waist-high tree, but it will not break the bamboo. The main reason is that the bamboo fiber material has high strength, good elasticity and low density. Its strength is 3 to 4 times that of steel. Higher tensile strength and compressive strength; the cross section of bamboo is circular, the outer curved surface is under tension and the inner curved surface is under compression, and has strong bending stiffness. In the current bamboo product processing process, it is generally painted on the surface Varnish, but there are problems of poor waterproof effect, poor flexibility, and low adhesion strength. Breaking through the performance bottleneck of bamboo products has very important economic...

[0002] Bamboo has excellent toughness. A hurricane can easily blow off a waist-high tree, but it will not break the bamboo. The main reason is that the bamboo fiber material has high strength, good elasticity and low density. Its strength is 3 to 4 times that of steel. Higher tensile strength and compressive strength; the cross section of bamboo is circular, the outer curved surface is under tension and the inner curved surface is under compression, and has strong bending stiffness. In the current bamboo product processing process, it is generally painted on the surface Varnish, but there are problems of poor waterproof effect, poor flexibility, and low adhesion strength. Breaking through the performance bottleneck of bamboo products has very important economic benefits and social value
