Problems solved by technology

[0002] Bamboo is a rich natural resource with high hardness and good wear resistance. Some building materials made of bamboo can replace wood with bamboo to relieve the tension of wood. However, most of the bamboo produced by people at present has no flame-retardant function. When using bamboo as the floor and wall panels, they will catch fire and burn when they encounter an open flame, which does not meet the fire protection requirements.

Embodiment 1

[0023] a. First remove the bamboo green layer of the bamboo, and then cut the remaining bamboo yellow into bamboo slices with a width of 1 cm and a thickness of 0.3 cm, and then place each bamboo slice in a 6% alum aqueous solution by weight Preservatives are soaked and placed in a steaming tank at 100 degrees Celsius for 1 hour of cooking and antiseptic treatment, then dehydrated and drained, and dried to a water content of 12%;

[0024] b. Then the dried bamboo pieces are divided into 2 mm wide and 1 mm thick bamboo filaments by a splitting machine, and the bamboo filaments are soaked in a flame retardant solution made of phosphoric acid and boric acid for 1 hour. The composition and weight percentage of the flame retardant liquid are 4% phosphate, 5% boric acid, and 3.5% phosphorus / nitrogen fire retardant. Among them, the phosphorus / nitrogen fire retardant contains 35% phosphorus and 65 nitrogen. % (That is, phosphorus is 1.2% of the flame-retardant liquid, and nitrogen is 2.3%...

Embodiment 2

[0029] a. First remove the bamboo green layer of the bamboo, and then cut the remaining bamboo yellow into bamboo slices with a width of 2 cm and a thickness of 0.5 cm, and then place each bamboo slice in 4% alum by weight. Aqueous preservative is soaked and placed in a steaming tank at 110°C for 2 hours of cooking and antiseptic treatment, then dehydrated and drained, and dried to a water content of 11%;

[0030] b. Then the dried bamboo slices are divided into 4 mm wide and 2 mm thick bamboo filaments by a splitter, and the bamboo filaments are soaked in a flame retardant solution made of phosphoric acid and boric acid for 3 hours. The composition and weight percentages of the flame retardant liquid are phosphate ester 6%, boric acid 8%, phosphorus / nitrogen fire retardant 4%, wherein the phosphorus / nitrogen fire retardant contains 40% phosphorus and 60 nitrogen. % (That is, phosphorus is 1.6% of the flame-retardant liquid, nitrogen is 2.4% of the flame-retardant liquid), the bal...

Abstract

The production process of flame-retardant shaped bamboo material includes the steps of: cutting bamboo into bamboo sheet, soaking in preservative and steaming antisepsis, cutting dried bamboo sheet into bamboo filament, soaking the bamboo filament in flame-retardant liquid comprising phosphate ester and boric acid or borax, dewatering, soaking in the waterproof adhesive, drying, compression setting inside mold in over 50 MPa hydraulic press, solidification and cooling to set in a drying kiln, and demolding. In case of burning the bamboo material, the high temperature will make the formed bamboo material blacken and coke without flame. The flame-retardant shaped bamboo material is anticorrosive, waterproof, high in strength and high in toughness, and may be used as floor, wall and other building material.

Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to a flame-retardant molded bamboo material and a production method thereof. Background technique: [0002] Bamboo is a rich natural resource with high hardness and good abrasion resistance. Some building materials made of bamboo can replace wood with bamboo and relieve the tension of wood. However, most of the bamboos made by people currently have no flame retardant function. When using bamboo as a floor or wall panel, it will catch fire when it encounters an open flame, which does not meet the fire protection requirements. Summary of the invention: [0003] The purpose of the present invention is to provide a flame-retardant molded bamboo material and a production method thereof. When the bamboo material is used as a floor or wall panel, it will not catch fire when encountering an open flame, and can meet the requirements of fire protection. [0004] The technical scheme o...
