Abstract
The invention discloses a flame-retardant bamboo board. The bamboo board is formed by impregnating a large number of bamboo chips, bamboo bundle strips or bamboo filaments into which flame retardant treating liquid penetrates into an adhesive and pressing, wherein the unit thickness of the bamboo chips, bamboo bundle strips or bamboo filaments is less than 3mm. The invention discloses a method for preparing the flame-retardant bamboo board, which comprises the following steps of: cutting fresh raw bamboo into bamboo sections with certain length, removing bamboo green and tabasheer, and sectioning into bamboo strips with certain length and width, or scraping outer-layer bamboo green off fresh raw bamboo, cutting into bamboo sections with certain length, and grinding and combing the bamboo sections into the bamboo bundle strips or bamboo filaments; drying the bamboo chips, bamboo bundle strips or bamboo filaments; putting the bamboo chips, bamboo bundle strips or bamboo filaments into a pressure container, and vacuumizing; making the flame retardant treating liquid penetrate into the bamboo chips, bamboo bundle strips or bamboo filaments by a pressure impregnation method; drying the bamboo chips, bamboo bundle strips or bamboo filaments; impregnating the bamboo chips, bamboo bundle strips or bamboo filaments into the adhesive; and pressing and integrating into the bamboo board. The invention has the advantages that: the flame-retardant property of the bamboo board can be effectively improved, and unsafe factors in links of production, storage, transportation, use and the like are eliminated.
Description
Technical field
The present invention relates to a kind of fire-retardant bamboo board, the invention still further relates to the preparation method of this fire-retardant bamboo board.
Background technology
After the slogan of wood substituted by bamboo proposed, the bamboo processing utilization level of China was in the first place in the world always.Since the seventies, successively developed all kinds of sheet materials such as bamboo mat plywood, bamboo weaving bamboo plywood, bamboo wood laminate, bamboo plywood, bamboo integration plate, bamboo-wood plyboard, be widely used in fields such as building, vehicle, packing, decoration, furniture.Along with the raising of people's living standard, bamboo board enters in the home decoration of common people family more and more.Many weeks, bamboo wood is a kind of combustible material, causes fire easily, all exists unsafe factor in links such as production, storage, transportation and uses.Bamboo wood and timber are still existing certain difference aspect chemical composition, the structure composition.The research of timber and bamboo wood flame-retarded technology aspect, mainly based on timber, the technology of bamboo wood fire retardant, flame retarding process aspect is still rarely seen.
Summary of the invention
The object of the present invention is to provide a kind of fire-retardant bamboo board, the present invention also aims to provide the preparation method of this fire-retardant bamboo board.
The technical scheme of the fire-retardant bamboo board of the present invention, it is by the bamboo chip of many infiltration fire retardant treatment fluids, bamboo bundle bar or bamboo silk, forms through suppressing after the dip bonding agent, the element thickness of described bamboo chip, bamboo bundle bar or bamboo silk is within 3 millimeters.
The method for preparing this fire-retardant bamboo board, fresh former bamboo is cut into the bamboo section of certain-length, remove surf green, tabasheer, dissect into the bamboo chip of certain-length and width, or fresh former bamboo scraped off outer field surf green, be cut into the bamboo section of certain-length, the bamboo section is rolled comb separate well-thought-out plan bundle bar or bamboo silk, then with bamboo chip, bamboo bundle bar or bamboo silk are dry to be handled, then with bamboo chip, bamboo bundle bar or bamboo silk place and vacuumize processing in the pressure vessel, then with bamboo chip, bamboo bundle bar or bamboo silk make the fire retardant treatment fluid be penetrated into bamboo chip by the processing method of impregnating by pressure, the inside of bamboo bundle bar or bamboo silk, then with bamboo chip, bamboo bundle bar or bamboo silk are dry to be handled, then with bamboo chip, bamboo bundle bar or the agent of bamboo silk dip bonding, compacting is integrated into bamboo board then.
Described bamboo chip, bamboo bundle bar or bamboo silk are placed vacuumizes processing in the pressure vessel, its vacuum is at 0-0.1Mpa.
Described fire retardant treatment fluid comprises the component of following components by weight percentage: 15%-40%, all the other are water.
Describedly make the fire retardant treatment fluid be penetrated into the inside of bamboo chip, bamboo bundle bar or bamboo silk bamboo chip, bamboo bundle bar or the bamboo silk processing method by impregnating by pressure, the pressure that its impregnating by pressure is handled is 0.8Mpa-1.6Mpa, time is 0.5 hour-4 hours, and treatment temperature is 20 ℃-100 ℃.
Described with bamboo chip, bamboo bundle bar or the dry processing of bamboo silk, its drying is handled to water content 6%～15%.
The beneficial effect of the fire-retardant bamboo board of the present invention is, can improve the fire resistance of bamboo board effectively, eliminates the unsafe factor of links such as production, storage, transportation and use.Bamboo board after flame treatment, its range of application obtain enlarging, and can be applied to the place that fire-protection rating is had relatively high expectations widely, further are applicable to every field such as building, transportation, packing, furniture, decoration, light industry.
