Description
Technical field
The present invention relates to a kind of fire-retardant material, more particularly, relate to a kind of fireproof interface mortar and its production and application.
Background technology
Fire has become one of great disaster of harm humans safety of life and property; various bamboo-wood structure buildings are inflammable buildings; various concrete and Steel Structure Work are in the high temperature more than 300 ℃; it or not explosion; lose intensity exactly and cave in, so people develop multiple inorganic and organic fire prevention coating, be sprayed on the surface of civil structure building, concrete and Steel Structure Work; they are protected in fire, avoid or reduce the loss that fire causes.
The frie retardant coating kind is numerous, can be divided into inorganic salts by its composition is the organic type frie retardant coating of base-material as the inorganic type frie retardant coating of base-material with natural or synthetical resin, by its dispersion medium water-soluble and solvent-borne type of can classifying, expanded polystyrene veneer and non-expansion type can be divided into by its fire prevention mechanism, facing type and structure-type can be divided into by its functions of use.Several frie retardant coatings commonly used are as follows
Facing expanding fire-proof paint: two fluorine amine-urea-copolyoxymethylenes, titanium dioxide, antimonous oxide, tetramethylolmethane and phosphoric acid; Trimeric cyanamide Precondensed UreaFormaldehyde Resin frie retardant coating: trimeric cyanamide Precondensed UreaFormaldehyde Resin, Sodium Silicofluoride, water, tetramethylolmethane and polyphosphoric acid amine; Expanded polystyrene veneer inorganic fireproof coating: base-material (aluminium hydroxide, phosphoric acid, water), composite flame-retardant agent, alchlor, titanium dioxide, urea-formaldehyde resin, urea, softening agent and water; Uninflammability inorganic fireproof coating: potassium silicate, expanded vermiculite, glass powder, titanium dioxide, red iron oxide, condensation of aluminum phosphate and water.As seen from the above, how many organic coatings contains formaldehyde, trimeric cyanamide, fluorochemical, and during burning, these organism will discharge some obnoxious flavoures, and human body and environment are had a strong impact on; Most of raw material is all more valuable, non-renewable, causes price higher.
In engineering construction, often need the warming plate processing of preventing fires, generally adopt two kinds of methods: a kind of is the above-mentioned frie retardant coating of spraying on warming plate, and another kind is on the surface nonwoven layer to be set earlier when the preparation warming plate, and the non-woven fabrics of tearing then carries out surface-coated again.The frie retardant coating of spraying not only exists above-mentioned environmental pollution, shortcoming that cost is high, and itself and finishing mucilage character are inconsistent, and the interface differs greatly, and causes the defective at interface easily, and then causes hidden danger of quality.Non-woven fabric compounded plate resistance combustion has further increased cost on the one hand, and easily comes off, and is unfavorable for reclaiming.
