Abstract
The invention discloses a multifunctional low-cost timber fire retardant and a preparation method thereof. The multifunctional low-cost timber fire retardant comprises, by mass, 20-40% of phosphoric acid, 10-20% of urea, 10-20% of melamine, 5-15% of a boron compound, 5-30% of water-soluble ammonium polyphosphate, 2-6% of sodium molybdate, 0.5-3% of fatty alcohol polyoxyethylene ether and 0.1-2% of chlorothalonil. Phosphoric acid, urea and melamine undergo an in-situ reaction to produce carbamidophosphate, the carbamidophosphate, the boron compound and the water-soluble ammonium polyphosphate are compounded, and the compound is added with sodium molybdate as a smoke inhibitor, fatty alcohol polyoxyethylene ether as a surfactant and chlorothalonil as a mildew-resistant bactericide. The multifunctional low-cost timber fire retardant has good flame retardation and good smoke inhibition performances, has no halogen and low toxicity, satisfies environmental protection requirements and has effects of corrosion-resistant, mildew-resistant and anti-moth effects.
Description
Technical field
The present invention relates to wood fire retardant technical field, specifically a kind of multi-functional, low cost wood fire retardant and preparation method thereof.
Background technology
Timber, owing to having light weight, higher-strength, the easily feature such as processing and wide material sources, has been widely used in the fields such as building, ornament materials, furniture.But timber easily burns, and apt to rot and yielding etc., therefore, necessary protective treatment is carried out to timber very necessary, comprise flame treatment, preservative treatment etc.At present, be all carry out single process mostly to timber, namely respectively by the medicament such as fire retardant, anticorrisive agent, timber repeatedly processed, so not only time-consuming, effort, and expense is also high, is also unfavorable for batch production etc.
Summary of the invention
The object of the present invention is to provide a kind of flame-retardant smoke inhibition, mildew-resistant and multi-functional, low cost wood fire retardant easy to use and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multi-functional, low cost wood fire retardant, its component by mass percent proportioning is: phosphoric acid 20% ~ 40%, urea 10% ~ 20%, melamine 10% ~ 20%, boron compound 5% ~ 15%, water-soluble poly ammonium phosphate 5% ~ 30%, sodium molybdate 2% ~ 6%, AEO 0.5% ~ 3%, Bravo 0.1% ~ 2%.
The mass percent concentration of described phosphoric acid is 75% ~ 85%.
Described boron compound is one or more mixtures in boric acid, borax, sodium tetraborate, eight boric acid disodiums, hydration zinc borate, borate.
The preparation method of a kind of multi-functional, low cost wood fire retardant of the present invention, comprises the following steps:
(1), each component is taken by mass percent proportioning;
(2), phosphoric acid, urea and melamine are added water be made into homogeneous solution and react after 0.5 ~ 2 hour at 70 DEG C ~ 110 DEG C temperature, be cooled to room temperature, then boron compound, water-soluble poly ammonium phosphate, AEO and Bravo is added, after mixing, obtain that one of the present invention is multi-functional, low cost wood fire retardant.
The invention has the beneficial effects as follows, compared with prior art, after phosphoric acid, urea and melamine reaction in-situ are obtained carbamidophosphoric acid salt by the present invention, compound is carried out again with boron compound and water-soluble poly ammonium phosphate, and to add sodium molybdate be surfactant and Bravo as smoke suppressant, AEO is antimildew disinfectant, the wood fire retardant obtained not only has good fire resistance, and smoke suppressing might as well, Halogen, low toxicity and meet environmental requirement, have anticorrosion, mildew-resistant, mothproof effect simultaneously; Preparation method provided by the invention is simple, and cost is low, is easy to suitability for industrialized production.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.
A kind of multi-functional, low cost wood fire retardant, its component by mass percent proportioning is: phosphoric acid 25%, urea 15%, melamine 15%, hydration zinc borate 15%, water-soluble poly ammonium phosphate 20%, sodium molybdate 6%, AEO 3%, Bravo 1%.Wherein, the mass percent concentration of described phosphoric acid is 75% ~ 85%.
Its preparation method is: (1), take each component by mass percent proportioning; (2), phosphoric acid, urea and melamine are added water be made into homogeneous solution and react after 0.5 ~ 2 hour at 70 DEG C ~ 110 DEG C temperature, be cooled to room temperature, then hydration zinc borate, water-soluble poly ammonium phosphate, AEO and Bravo is added, after mixing, obtain that one of the present invention is multi-functional, low cost wood fire retardant.
