Abstract
A kind of wooden bamboo wood highly effective flame-retardant processing method, dried wooden bamboo square bar is immersed in BAS, then wooden bamboo square bar is taken out from BAS and carry out drying, after removing the moisture in wooden bamboo side by drying, wooden bamboo side is entered in the sodium hydroxide solution of zinc hydroxide, zinc hydroxide is rapidly to internal penetration with sodium hydroxide solution, and generates the Firebrake ZB with anti-flaming function in inside, wooden bamboo side with boric acid generation chemical reaction.Adopt this inventive method process wood bamboo wood, it is inner that Firebrake ZB is evenly distributed on wooden bamboo side, thus reach good flame retardant effect.
Description
Technical field
The invention belongs to wooden bamboo wood functionality improvement field, be specifically related to a kind of wooden bamboo wood highly effective flame-retardant processing method.
Background technology
Timber and bamboo wood have natural texture, gloss and color, the ratio of strength to weight is high, possess preferably heat insulation and electrical insulation capability, are easy to processing simultaneously, can be widely used in furniture, indoor and outdoor decoration field, also can be used as the basic material of wooden bamboo engineering structure simultaneously.But timber and bamboo wood are also combustible materials, and many fire occur and spread all directly related with timber and bamboo wood, cause application to be greatly limited simultaneously.
Be easy to the shortcoming of burning for wooden bamboo wood, people have carried out the flame-retardant modified treatment research of many wooden bamboo woods, achieve some achievements.But, conventional wooden bamboo wood fire retardant treatment process adopts Firebrake ZB to carry out in flame retardant treatment process to wooden bamboo wood, its process is loaded down with trivial details, efficiency is low, and Firebrake ZB is in a solvent in suspension, limited to the permeability of wooden bamboo wood, in Fire-retarding of Wood, fire retardant is difficult to the degree of depth and enters wooden bamboo wood deep layer, and fire retardant is at the inner skewness of wooden bamboo wood, cause the wooden bamboo wood fire resistance after processing undesirable.Therefore, carrying out wooden bamboo wood highly effective flame-retardant Processing Technology Research, realize the process of wooden bamboo wood highly effective flame-retardant, having significant for significantly improving timber added value.
Summary of the invention
Technical problem solved by the invention is to provide a kind of wooden bamboo wood highly effective flame-retardant processing method, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of wooden bamboo wood highly effective flame-retardant processing method, the notable feature being different from conventional wooden bamboo wood flame-proof treatment method is: be immersed in BAS by dried wooden bamboo square bar, and it is inner that boric acid is easy to enter wooden bamboo square bar with water.Then wooden bamboo square bar is taken out from BAS and carry out drying, after removing the moisture in wooden bamboo side by drying, wooden bamboo side is entered in the sodium hydroxide solution of zinc hydroxide, zinc hydroxide is rapidly to internal penetration with sodium hydroxide solution, and generates the Firebrake ZB with anti-flaming function in inside, wooden bamboo side with boric acid generation chemical reaction.Compared with directly processing with conventional zinc borate flame retardant, adopt this inventive method process wood bamboo wood, it is inner that Firebrake ZB is evenly distributed on wooden bamboo side, thus reach good flame retardant effect.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of wooden bamboo wood highly effective flame-retardant processing method, concrete steps are as follows:
(1) boric acid is joined in the hot water of 50 DEG C, fully stir the even boric acid aqueous solution of preparation.The mass ratio of boric acid and water is 1:10.
(2) join in sodium hydrate aqueous solution by zinc hydroxide, fully stir the sodium hydrate aqueous solution of the even zinc hydroxide of preparation, in its solution, the mass ratio of zinc hydroxide, NaOH, water is 3:1:6.
(3) wooden bamboo material is processed into the square bar that thickness is 10 ~ 200mm or sheet material; Then being placed in drying kiln for drying to moisture content is about 10%; Again dried wooden bamboo wood is placed in boric acid aqueous solution immersion treatment 10 ~ 20min;
(4) wooden bamboo wood is taken out from boric acid aqueous solution, be placed in dry kiln and soak 10 ~ 20min at the sodium hydrate aqueous solution moving to zinc hydroxide after dry 30 ~ 60min at 60 DEG C of temperature;
(5) taken out from the sodium hydrate aqueous solution of zinc hydroxide by wooden bamboo wood, delivering to dry kiln, at the temperature of 90 DEG C, be dried to moisture content be about 10%, both obtained wooden bamboo square bar or the sheet material with high efficiency flame retardance.
Beneficial effect: utilize the zinc borate flame retardant in the wooden bamboo wood of process of the present invention to be generate at the inner chemical reaction by boric acid and zinc hydroxide of wooden bamboo wood.BAS and zinc hydroxide solution extremely strong to wooden bamboo wood permeability, therefore, zinc borate flame retardant can be uniformly distributed in wooden bamboo wood, plays good flame retardant effect.Utilize the wooden bamboo wood flame retardant rating after this inventive method process can reach B1 level.
