Problems solved by technology

[0003] With the increasing demand for wood in our country, bamboo wood gradually replaces some wood to occupy the market. Due to the special softness of bamboo itself, it is more and more popular in making handicrafts. However, most of the existing bamboo handicrafts are made of raw bamboo , opening, wet carbonization, drying, dipping, drying again, pressing, and finished products. Due to the flammability of bamboo itself, there is a fire hazard when using bamboo handicrafts

Embodiment 1

[0018] 1) sawing off the log, splitting it into pieces, processing the log into strips, smoothing the burrs on the side of the bamboo, and the width of a single bamboo is 2cm;

[0019] 2) Put the bamboo slices treated in step 1) into -25°C for quick freezing for 10 minutes, take them out and soak them in a fire-retardant solution at 30°C for 12 hours, specifically, put the bamboo slices into the fire-retardant solution after quick-freezing and soak them at 30°C Soak in heat preservation for 6 hours, slowly raise the temperature to 40°C, and soak in heat preservation for 6 hours;

[0020] The flame retardant solution is: 25 parts of ureidophosphate GUP, 4 parts of microencapsulated red phosphorus, 10 parts of phosphoric acid, 4 parts of phosphorylated castor oil, 6 parts of multidirectional complexing central atom zinc, and 3 parts of sodium lauryl sulfate;

[0021] The components of ureidophosphate GUP are: 20% phosphorus oxyacid, 20% dicyandiamide, and the balance is water. ...

Embodiment 2

[0026] 1) Saw the log, split it, process the log into strips, grind the burrs on the side of the bamboo, and the width of a single bamboo is 3cm;

[0027] 2) Put the bamboo slices processed in step 1) into -25°C for quick freezing for 12 minutes, take them out and soak them in a fire retardant solution at 35°C for 18 hours. Soak in heat preservation for 9 hours, slowly raise the temperature to 40°C, and soak in heat preservation for 9 hours;

[0028] The flame retardant solution is: 25 parts of ureidophosphate GUP, 5 parts of microencapsulated red phosphorus, 13 parts of phosphoric acid, 5 parts of phosphorylated castor oil, 6 parts of multidirectional complexing central atom zinc, and 3 parts of sodium lauryl sulfate;

[0029] The components of ureidophosphate GUP are: 30% phosphorus oxyacid, 30% dicyandiamide, and the balance is water.

[0030] 3) Dry the soaked bamboo chips in step 2, at a drying temperature of 60°C, keep warm for 25 minutes, until the moisture content is ...

Embodiment 3

[0034] 1) Saw off the log, split it, process the log into strips, grind the burrs on the side of the bamboo, and the width of a single bamboo is 4cm;

[0035] 2) Put the bamboo slices treated in step 1) into -25°C for quick freezing for 15 minutes, take them out and soak them in a flame retardant solution at 40°C for 24 hours, specifically, put the bamboo slices into the flame retardant solution after quick freezing, soak at 30°C Soak in heat preservation for 12 hours, slowly raise the temperature to 40°C, and soak in heat preservation for 12 hours;

[0036] The flame retardant solution is: 25 parts of ureidophosphate GUP, 6 parts of microencapsulated red phosphorus, 16 parts of phosphoric acid, 6 parts of phosphorylated castor oil, 6 parts of multidirectional complexing central atom zinc, and 3 parts of sodium lauryl sulfate;

[0037] The components of ureidophosphate GUP are: 40% phosphorus oxyacid, 40% dicyandiamide, and the balance is water.

Abstract

The invention discloses a manufacturing method of flame-retardant bamboos. The manufacturing method comprises the following steps that 1) sawing-off and slicing are carried out on a log so as to enable the log to be processed into strips, and burrs on the side edges of the bamboo strips are flattened, wherein the width of each single bamboo strip is 2-4 cm; 2) the bamboo strips processed in the step 1) are put into the environment with the temperature of 25 DEG C below zero for quick-freezing for 10-15 minutes, then are taken out and are put into a flame-retardant solution with the temperatureof 30-40 DEG C for soaking for 12-24 hours; 3) drying treatment is carried out on the bamboo strips which are soaked in the step 2), wherein the drying temperature is 60 DEG C, then heat preservationis carried out for 20-30 minutes until the moisture content is 30-40%, the temperature is reduced to 50 DEG C, the heat preservation is carried out for 20-30 minutes until the moisture content is reduced to be less than or equal to 10%, and drying is completed; and 4) glue dipping and hot pressing treatment are carried out on the bamboo strips which are treated in the step 3), then cold drying iscarried out, the flame-retardant solution is uniformly sprayed on the surface of the bamboo strips in a cross manner after cold drying, and the bamboos are obtained after being subjected to natural airdrying. The bamboos manufactured through the method are good in flame retardant effect and harmless to the body.

Description

technical field [0001] The invention relates to the field of bamboo and wood preparation, in particular to a method for preparing flame-retardant bamboo and wood. Background technique [0002] Bamboo is my country's second forest resource. The main material output accounts for about 1 / 10 of the wood. The resource is rich and concentrated. Bamboo and wood are renewable resources. After the forest is formed, it can be reused as long as it is properly managed. Bamboo itself grows fast and can be harvested every 3-5 years. [0003] With the increasing demand for wood in our country, bamboo wood gradually replaces some wood to occupy the market. Due to the special softness of bamboo itself, it is more and more popular in making handicrafts. However, most of the existing bamboo handicrafts are made of raw bamboo , opening, wet carbon carbonization, drying, dipping, drying again, pressing, and finished products. Due to the flammability of bamboo itself, there is a fire hazard when...
