Description
Technical field
The present invention relates to building product fields more particularly to a kind of low cigarette environment-friendly fireproof coating and preparation method thereof.
Background technique
With the continuous increase of Chinese national economy, various industries especially building trade often will appear fire incident,
Cause important casualties and property loss, trace it to its cause be primarily due to they used in process of construction it is many easily
The substance and material of combustion, and a large amount of smog and toxic gas are generated in combustion, these materials are investigated according to relevant departments
All without passing through various flame retardant treatments, great injury and injures and deaths are just caused.
According to related news, the fire that our various regions occur can be found everywhere, and also constantly increase, according to statistics the whole nation in 1999
Fire 39571 occurs to rise, death about 2652 people, about 5977 people of wound, about 11.2 hundred million yuan of direct economic loss；And fire in 2000
Calamity is about 40000, extremely about 2800 people, injury about 4000 people, and about 1,200,000,000 yuan of direct economic loss.In consideration of it, country is related
Department and expert call everybody to use nonflammable material in process of construction as far as possible, and to reach national requirements
Fire-protection rating, for example as the insulating layer of building envelopes has to reach corresponding fire-protection rating, could preferably reach in this way
Flameproof effect.The generation of fire incident in order to prevent, implements fire-fighting work conscientiously, fulfils the work of " putting prevention first, combine prevention with fire fighting "
Make policy, country has formulated corresponding laws and regulations, calls using fireproof coating and fire proofing to prevent fire, therefore
Fireproofing becomes more and more important, more more and more urgent.From the point of view of us now used construction material, most of ratios are easier to
Combustion, there are many violations of rules and regulations, substantially also without just directly applying by corresponding fire prevention processing, and in combustion
There are no good fire prevention measure, masses' awareness of the importance of fire prevention is weaker, and many accidents is caused constantly to occur.In numerous fire prevention means
It is that can achieve preferable flameproof effect using fireproof coating that middle comparison is effectively and application is wider.
Traditional fireproof coating is mainly based upon macromolecule matrix, including propylene acid esters, epoxy resin, and esters of silicon acis etc. is organic
Resin.And their main application technology is spraying, is brushed, roller coating etc., another method is exactly that material surface is directly soaked
Stain in coating, make its infiltrate through in material achieve the effect that it is fire-retardant.However these technologies are there are problems, for example method
It is too cumbersome, furthermore a large amount of raw material and chemicals are needed, serious pollution, and duplicate brushing, meeting are caused to environment
Cause the adhesion strength between coating not strong, the problem of being easy to fall off.
Thus, it is also very desirable to a kind of effective study on formula of fireproof paint is developed, so that in fire generating process, effectively
Inhibit the sprawling of fire, while smoke creating amount can be significantly reduced, for reducing fire casualties, improves related places
Fire safety grade.
