Description
Technical field
The present invention relates to a kind of fire proofing materials, more specifically to a kind of environmental-protection flame-retardant mortar and preparation method thereof
And application.
Background technique
Fire has become one of the disaster for endangering human life and property safety, and various bamboo-wood structure buildings are easy
Combustion is built, and various concrete and structural steelwork are not explosions, exactly lose intensity and collapse in 300 DEG C or more of high temperature,
Therefore people develop a variety of inorganic and organic fire prevention coating, are sprayed on the table of civil structure building, concrete and structural steelwork
Face is protected them in a fire, avoids or reduce loss caused by fire.
Fireproof coating kind is numerous, by its composition can be divided into inorganic type fireproof coating using inorganic salts as base-material with
Using natural or artificial resin as the organic type fireproof coating of base-material, can classify water-soluble and solvent by its decentralized medium
Type can be divided into intumescent and non-expansion type by its fireproofing mechanism, can be divided into facing type and structural type using function by it.It is several normal
Fireproof coating is as follows
Facing expanding fire-proof paint: double fluorine amine-urea-formaldehyde copolymer, titanium dioxide, antimony oxide, pentaerythrite and phosphorus
Acid；Melamine pollopas fireproof coating: melamine pollopas, prodan, water, pentaerythrite and polyphosphoric acid amine；
Intumescent inorganic fireproof coating: base-material (aluminium hydroxide, phosphoric acid, water), composite flame-retardant agent, alchlor, titanium dioxide, ureaformaldehyde tree
Rouge, urea, plasticizer and water；Noninflammability inorganic fireproof coating: potassium silicate, expanded vermiculite, glass powder, titanium dioxide, iron oxide red,
Condensation of aluminum phosphate and water.From the above, it can be seen that how much organic coating contains formaldehyde, melamine, fluoride, when burning, these
Organic matter will discharge some pernicious gases, seriously affect to human body and environment；Most of raw material is all relatively valuable, can not be again
It is raw, cause price higher.
It in engineering construction, generally requires to carry out fire prevention processing to insulation board, uses two methods under normal conditions: is a kind of
It is that above-mentioned fireproof coating is sprayed on insulation board, another kind is that nonwoven layer first is arranged on surface when preparing insulation board, so
After non-woven fabrics of tearing carry out surface coating again.The fireproof coating of spraying not there is only above-mentioned environmental pollution, disadvantage at high cost,
And itself is inconsistent with finishing mucilage property, and interface differs greatly, and is easy to cause the defect at interface, it is hidden in turn result in quality
Suffer from.The non-woven fabric compounded fire-retardant one side of plate further increases cost, and easy to fall off, is unfavorable for recycling.
