Abstract
A flame-retarding agent suitable for cotton cloth, chemical fibre, paper and wood is prepared from urea, phosphoric acid, borax, boric acid and water through proportioning, feeding water, urea and phosphoric acid in jacketed reactor, heating until full dissolving, cooling, adding borax and boric acid, and regulating pH value to 7. Its advantages are transparent, colourless, no toxicity, no odour, no pollution, no corrosion, convenient application and no influence on physical nature of the treated object.
Description
The present invention relates to a kind of fire-proof flame-retarded agent, the fire protection flame retarding that is specially adapted to inflammable substance such as cloth, chemical fibre, paper, carpet, timber is handled.
Existing aqua fire-proof flame-retarded agent, have nontoxic, free from environmental pollution, do not have advantage such as corrosion, but poor transparency leaves watermark after the use, influence decorative effect, sprays or is immersed in above door curtain, curtain, the window curtain etc., can make the cloth hardening.
The objective of the invention is to overcome the weak point in the background technology and provide that material softness after a kind of colourless, transparent, nontoxic, tasteless, no burn into is handled is constant, fire resistance good, fire-proof flame-retarded agent easy to use.
The object of the present invention is achieved like this: this fire-proof flame-retarded agent is made up of urea, phosphoric acid, borax, boric acid and water, and its weight percent is respectively urea 10.5-14.5%, phosphoric acid 3-7%, borax 1-5%, boric acid 2.5-6.5%, water 70-80%.Each component is weighed up in proportion, earlier water, urea and phosphoric acid are put into the interlayer reactor and be heated to 100 ℃, dissolve fully until mixture, add borax and boric acid after cooling, transferring to pH value is 7, and filtration is made.
Purpose of the present invention can also realize by following technical measures: the best proportioning (weight percent) of each component is urea 12.5%, phosphoric acid 5.0%, borax 3.0%, boric acid 4.5%, water 75%.Required water is best with the deionized water.
The present invention compared with prior art has following advantage:
1, this product water white transparency, nontoxic, tasteless, pollution-free;
2, because of this product is neutral, therefore there is not corrosion;
3, easy to use, to spray, be coated with, all can flood, the character of object being treated, gloss, feel, flexibility all do not change.
4, fire resistance is good, and the high temperature that ability is 700 ℃ also can be prevented naked light;
5, cost is low, only is 1/2nd of like product.
Below in conjunction with embodiment in detail the present invention is described in detail: example 1, get 25 parts in urea, 0 part of phosphatase 11,6 parts of boraxs, 9 parts of boric acid, 150 parts in water, add up to 200 parts, every part with 1 kilogram of calculating, and promptly urea accounts for 12.5% of total amount for 25 kilograms, 0 kilogram of phosphatase 11, account for 5.0%, 6 kilograms of boraxs account for 3%, 9 kilograms of boric acid, account for 4.5%, 150 kilograms in water accounts for 75%, after each component weighs up according to the above ratio, earlier with water, urea and phosphoric acid are put into the interlayer reactor and are heated to 100 ℃, dissolve fully until mixture, add borax and boric acid after cooling, stirring fully reacts it, transfer to after pH value is 7 with boric acid, refilter packing and make finished product.
With the 100 kilograms of fire-proof flame-retarded agents of preparing burden is example, is equipped with the explanation of set of dispense schedule of proportion, and the preparation method is the same.
