Abstract
The present invention relates to a kind of fire retardant and its preparation process, raw material includes being formulated by following raw material components, Ludox, boric acid, urea, carbonate, phosphoric acid, water；The invention further relates to the manufacture craft of fire retardant, the fire retardant that the present invention makes is with obvious effects and with good stability.
Description
Technical field
The present invention relates to a kind of fire retardants, and in particular to a kind of timber fire retardant and the technique for preparing fire retardant.
Background technology
Wood fire retardant is the auxiliary agent that timber is prevented to be ignited and inhibit flame propagation.With extensive use scope.Have
Timber is a kind of porosity complexity natural organic substance being mainly made of cellulose, hemicellulose and lignin.Its main feature is that：
It does not dissolve, melt under common processing and use condition, thus processing method is different from synthesis macromolecule；In Wood molecules
Containing the oxygen-containing polar group such as substantial amounts of hydroxyl and methylol, thus hygroscopicity is strong, poor dimensional stability；Still have in addition to inflammable easily
The characteristics of rotten and chemically reactive degradation.The These characteristics of timber determine that the mainstream kind of wood fire retardant is all aqueous solution type production
Product, leading adding method are the methods of impregnating.
In existing fire retardant, organic fire-retardant is because releasing a large amount of toxic gases and expensive when it burns, without advocating
It uses；Resin type fire retardant, since flame retardant property is not ideal enough and there is the problems such as impregnating difficulty, processing material darkens,
It is not widely used.Using most wide inorganic combustion inhibitor, have many advantages, such as to derive from a wealth of sources, price is low, asepsis environment-protecting, but its anti-current
It is to be improved to lose performance.With fire-retardant the reach of science and the enhancing of people's environmental consciousness, there is good leach resistance
Environmental type fire retardant by be fire-retarding of wood the main direction of development.
The content of the invention
The shortcomings that overcome above-mentioned wood fire retardant and deficiency, it is an object of the invention to provide a kind of wood fire retardant and
Its preparation process.
Technical scheme is as follows：
A kind of wood fire retardant, which is characterized in that including being formulated by following raw material components according to weight percent：
Ludox 35~55%；
Boric acid 10~20%；
Urea 10~20%；
Carbonate 15~25%；
Phosphatase 11~5%；
Water 10~25%.
Further, the phosphoric acid is the solution that mass percent concentration is 60~80%.
Further, the carbonate is any one of sodium carbonate, potassium carbonate or its mixture.
Further, comprise the following steps：
A, phosphoric acid, boric acid are added in reaction kettle, stirred and heated, temperature is made to improve to 60~70 degree；
B, urea is added in into the reaction kettle, stirred evenly, and continuous heating, temperature is made to improve to 80~90 degree；
C, carbonate is added in into the reaction kettle, stirred evenly, and continuous heating, temperature is made to improve to 130~150
Degree；
D, reaction kettle is cooled to 80 degree, adds in water and Ludox, persistently stir and be cooled to 20 degree.
The present invention has the advantages that：
(1) wood fire retardant flame retardant effect provided by the invention is apparent and with good stability；
(2) wood fire retardant provided by the invention can complete sealing timber, prevent the pernicious gas in timber from running out of；
(3) wood fire retardant preparation process provided by the invention is simple, and it is common raw material to prepare raw material.

Temperature adds in 7% water and 45% Ludox to 80 degree, persistently stirs and is cooled to 20 degree.
Embodiment 3
5% phosphoric acid, 10% boric acid are added in reaction kettle, stirs and heats, temperature is made to improve to 60~70 degree；
10% urea is added in into the reaction kettle, is stirred evenly, and continuous heating, temperature is made to improve to 80~90 degree；To described
The mixture of 15% potassium carbonate and sodium carbonate is added in reaction kettle, is stirred evenly, and continuous heating, make temperature improve to 130~
150 degree；Reaction kettle is cooled to 80 degree, adds in 5% water and 55% Ludox, persistently stir and is cooled to 20 degree.
