Abstract
The present invention relates to a kind of fire-resistant coating for steel structure based on beidellite, the key component of following mass parts is included in its raw material：15 25 parts of beidellite, 15 30 parts of metal hydroxides, 5 12 parts of ethanol, 7 10 parts of calcium carbonate, 15 25 parts of talcum powder, 6 12 parts of silane, 6 12 parts of siloxanes, 58 parts of glass sand, 58 parts of resin.The present invention, as being combined in complex, makes fireproof coating in addition to fire retardant property using beidellite and metal hydroxides, additionally it is possible to maintains resistance to combustion, flame proof and the fire resistance property such as fire-retardant, can effectively protect surrounding combustible material.
Description
Technical field
The present invention relates to a kind of fireproof coating, and in particular to a kind of fire prevention of poly-organic acid system in steel structure fireproofing applies
Material.
Background technology
At present, fire prevention measure both domestic and external from principle for be divided into Dredging Method and blocking cut-off process, and blocking cut-off process be divided into it is outer
Envelope, screen method, spraying process.Fire proofing material is coated in body surface as one kind, has heat-insulated, anti-flaming, anti-flaming function
Material is used widely, and using the development that can effectively delay the intensity of a fire in construction material, prevents propagation of flame.
Application publication number CN103923545A patent application discloses a kind of fireproof coating, fireproof coating proportioning, double cyanogen
Amine, silicate, pentaerythrite, titanium dioxide, chlorinated paraffin, APP, acrylic emulsion, remaining is auxiliary agent, the fireproof coating
Nontoxic, nonirritant, in coating, caking property is good, attractive in appearance and good flame retardation effect.Existing fireproof coating exists anti-toward contact
The shortcomings of fiery time is short, and protection domain limits to.The fire-proof and thermal-insulation effect for further improving fireproof coating is still art technology
The direction that personnel make great efforts.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of steel construction based on beidellite for above-mentioned prior art
Fireproof coating, it has good fireproofing flame-resistant characteristic.
Technical scheme is used by the present invention solves the above problems：A kind of fire-resistant coating for steel structure based on beidellite,
The key component of following mass parts is included in its raw material：
Beidellite 15-25 parts,
Metal hydroxides 15-30 parts,
Ethanol 5-12 parts,
Calcium carbonate 7-10 parts,
Talcum powder 15-25 parts,
Silane 6-12 parts,
Siloxanes 6-12 parts,
Glass sand 5-8 parts,
Resin 5-8 parts.
Metal hydroxides of the present invention is magnesium hydroxide, aluminium hydroxide.
The particle diameter of talcum powder of the present invention is 100~350nm.
Glass sand of the present invention can be replaced with glass fibre.
Fire-resistant coating for steel structure of the present invention also includes pigment, water, thickener, defoamer.
Fire-resistant coating for steel structure of the present invention also includes levelling agent, curing agent.
Compared with prior art, the advantage of the invention is that：The present invention is using beidellite and metal hydroxides as compound
Combination, metal hydroxides is homogeneously dispersed in beidellite and reacted, the performance of reinforcement beidellite, fireproof coating except
Outside fire retardant property, additionally it is possible to maintain resistance to combustion, flame proof and the fire resistance property such as fire-retardant, can effectively protect easy fuel wood around
Material.
