Abstract

The invention discloses a kind of bamboo-made floor substrate fabrication process, it is concretely comprised the following steps：(1) raw bamboo is blocked, hacking, then goes blue or green de-etiolation, obtain bamboo chip；(2) bamboo chip is sent into the dry machine of dried disinfecting carbon, the temperature of the dry machine heating of dried disinfecting carbon is 160-190 DEG C, 2-4 hours heat times, is carbonized in bamboo chip table, carbonizing degree is 5%-30%, then carries out impregnation；(3) bamboo cane after impregnation is subjected to adjustable cast iron planes, gluing again, then according to designed structure group also, is sent into hot press and carries out hot pressing；(4) bamboo flooring after hot pressing carries out sanding, end system, top finishing after cooling after a while.

Description

A kind of bamboo-made floor substrate fabrication process

Technical field

The present invention relates to floor manufacture field, is in particular a kind of bamboo-made floor substrate fabrication process.

Background technology

With China's expanding economy, the imbalance between supply and demand of timber is more and more prominent, and the natural forest protection work that country takes Journey make it that the forest reserves are even more wretched insufficiency.Wood-based Panel Production using timber and wood machining residues as primary raw material, resource Limitation forces people to find new material resources.Bamboo is second forest reserves in China, and there are the category of bamboo class more than 70,1200 in the world A variety of, there are category, kind more than 500, bamboo resource very abundant more than 40 in China.China is located in the center of world's bamboo distribution, bamboo grove face 8,000,000 hectares of product, either first of total class of bamboo, area, accumulation and the cutting Jun Ju worlds.Fujian is China's bamboo Emphasis producing region, have the category of bamboo class 19, nearly kinds more than 200,89.4 ten thousand hectares of bamboo grove area, occupy the 12.4% of forest land area, Wherein 83.6 ten thousand hectares of mao bamboo woods area, 5.8 ten thousand hectares of small diameter bamboo, ranks first in the country.Bamboo material is applied to wood-based plate In industry, have great importance for the deficiency for alleviating the forest reserves.

The content of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of bamboo-made floor substrate fabrication process.

Present invention employs following technical scheme：A kind of bamboo-made floor substrate fabrication process, it is concretely comprised the following steps：

(1) raw bamboo is blocked, hacking, then goes blue or green de-etiolation, obtain bamboo chip；

(2) bamboo chip is sent into the dry machine of dried disinfecting carbon, the temperature of the dry machine heating of dried disinfecting carbon is 160-190 DEG C, is added Hot 2-4 hours time, it is carbonized in bamboo chip table, carbonizing degree is 5%-30%, then carries out impregnation；

(3) bamboo cane after impregnation is subjected to adjustable cast iron planes, gluing again, then according to designed structure group also, is sent into heat Press carries out hot pressing；

(4) bamboo flooring after hot pressing carries out sanding, end system, top finishing after cooling after a while.

Further, in step (2), the temperature of the dry machine heating of dried disinfecting carbon is 175 DEG C, 3 hours heat times.

Further, melamine modified urea-formaldehyde resin adhesive is used as maceration extract in step (3), concentration 15- 35%, the impregnation time is 10-15min, and temperature is 20-50 DEG C.

Beneficial effect using above technical scheme is：The invention provides a kind of bamboo-made floor substrate fabrication process, bamboo Material is for timber, the original feature with timber, and bamboo is in process, can using the high-quality glue kind for meeting national standard Harm of the materials such as formaldehyde to human body is avoided, also bamboo flooring utilizes advanced equipment and technology, by being impregnated to raw bamboo Processed with hot-pressing processing etc., the natural aesthetic feeling and floor tile with raw wood floor it is sturdy and durable.

The method of the production bamboo-made floor base material of the present invention, by the way that the bamboo cane feeding dry machine of dried disinfecting carbon is carried out disinfection Carbonization, the thermal efficiency is high, and penetrates inside bamboo cane, more helps the decomposition of sugar, protein inside bamboo cane, avoids bamboo cane mouldy Discoloration.

Embodiment

With reference to embodiment, the present invention will be further described：

Embodiment 1：

A kind of bamboo-made floor substrate fabrication process, it is concretely comprised the following steps：

(2) bamboo chip is sent into the dry machine of dried disinfecting carbon, the temperature of the dry machine heating of dried disinfecting carbon is 175 DEG C, the heat time 3 hours, it is carbonized in bamboo chip table, carbonizing degree is 5% -30%, then carries out impregnation；

(3) bamboo cane after impregnation is subjected to adjustable cast iron planes, gluing again, then according to designed structure group also, is sent into heat Press carries out hot pressing, and melamine modified urea-formaldehyde resin adhesive is used as maceration extract in the step, concentration 15-35%, leaching The glue time is 10-15min, and temperature is 20-50 DEG C.
