Abstract
The present invention relates to a fire retardant. Its composition is composed of (wt%) 15%_25% of ammonium sulfamate and 75%-85% of formamide, and its pH value is 7. Said invention possesses the following characteristics: the material treated by using said fire retardant can effectively prevent fire from spreading, can keep original form, colour and properties, does not produce devitrification, doesn't yellow or starch, its product is neutral, anticorrosive, and has no abnormal smell. The promient characteristic of said product lies in that its components can be infiltrated into fibres of nylon product, and it is laundry-proof and durable in effective acting time. Its application is simple and convenient, according to different requirements said product cna directly be injected into rew mother material or added into the raw mother material by means of immersion-rolling process in the course of production.
Description
The invention belongs to fire retardant, particularly a kind of combustion suppressing agent that adopts the amido series material.
Existing fire retardant kind is a lot, but all belongs to the composite fire retardant of element such as phosphorous, nitrogen, for example FRP-30 liquid flame retardant, WR-1 type fire retardant, the efficient flame retardant for textile of FP-FT.They have following deficiency:
1, use them to adopt and soak, spray, the scopiform formula is handled on the surface of article, and porous or be dissolved among the object does not fundamentally solve durable effectively fire-retardant.
2, some wash-resistant fabric product is after existing fire retardant is handled, the pulpboard of various degrees, and the phenomenon of losing colour has been destroyed the color and luster and the pliability of original article.
3, the fire-retardant intensity of existing fire retardant is also not very good, awaits further raising.
4, equal slant acidity of the general pH value of existing fire retardant or meta-alkalescence have the corrosion of distinct program to article.
The object of the present invention is to provide a kind of new combustion suppressing agent to overcome the deficiency that above-mentioned prior art exists.
The object of the present invention is achieved like this:
A kind of combustion suppressing agent is made up of Ammonium sulfamate and methane amide.
Its composition is:
Ammonium sulfamate 15%-25%
Methane amide 75%-85%
PH value=7 neutrality
The present invention has following characteristics:
1, do not adopt the compound fire retardants of making of ignition-proof element such as conventional phosphorus, nitrogen, boron, but adopt the amido series material.
2, the article of treated mistake can not be lighted, and go up gasoline even sprinkle, and also can not form fire, can prevent to block spreading of flame effectively.
3, the article of treated mistake can keep original state, color, character, crystallization not, not yellowing, not pulpboard.
4, product all is neutral, does not corrode the article free from extraneous odour of treated mistake.
5, the most outstanding characteristics of this product are that its component is oozed in nylon goods fiber, water-fast washing for a long time effectively.
6, using method is easy, and is various, can spray, brushes, soak, also can be according to the needs of different varieties, and directly be injected in the original masterbatch or implement to soak a pressing and rolling process in process of production, for the user provides sufficient choice and convenient.
Claims (2)
1, a kind of combustion suppressing agent is characterized in that: be made up of Ammonium sulfamate and methane amide.
2, combustion suppressing agent according to claim 1, its composition is:
Ammonium sulfamate 15%-25%
Methane amide 75%-85%
PH value=7 neutrality
