Abstract
The invention relates to an aqueous emulsion expansion-type fireproof mixed liquor and a processing technology for preparing a low-smoke halogen-free high-flame resistance wrapping tape. The mixed liquor comprises a water-soluble ammonium polyphosphate APP-type fire retardant, a foaming agent melamine, a charring agent pentaerythritol, a pigment anatase-type titanium dioxide, a filler, and a binder silicone-acrylic emulsion. Under the action of a high temperature or flame, the fireproof coating on the protected base severely expands, is charred and foams so that a non-combustible spongy charcoal layer of which the volume is dozens of times larger than the original coating is formed and the foam is filled with inactive gas and thus heat insulation effects are obtained.
Description
Technical field
The present invention relates to a kind of water-based emulsion expansion fire-proof mixed liquor and utilize this mixed liquor to prepare the processing technology of low-smoke bittern-free highly fire-proof band, belonging to a kind of processing technology and fire proofing material of inhibiting tape.
Background technology
And existing commercially high flame retardant band generally adopts at present at glass-fiber-fabric or other scrim surfaces coating AL (OH)
3, MG (OH)
2with water soluble acrylic acid mixed liquor, be also drying, rolling, cut and form.
AL (OH) under high temperature (250-350 DEG C)
3, MG (OH)
2heat can be absorbed and resolve into the compositions such as water, and playing fire retardation.But under lasting high temperature, will lose flame retardant effect and be formed without thermal insulation layer, high temperature easily enters core inside.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of fire resistance excellent (oxygen index (OI) > 60%), high temperature resistant (normal working temperature 180 DEG C), heat insulation, Halogen, tensile strength are high, a kind of water-based emulsion expansion fire-proof mixed liquor simple for production and utilize this mixed liquor to prepare the processing technology of low-smoke bittern-free highly fire-proof band.
The technical solution used in the present invention is for this reason: mixed liquor proportioning of the present invention is as follows: by water-soluble ammonium polyphosphate APP based flame retardant;
Blowing agent: melamine;
Carbon forming agent: pentaerythrite;
Color stuffing: anatase thpe white powder;
Binding agent: Silicone acrylic emulsion.
Proportioning and the weight ratio of this mixed liquor are as follows:
Water-soluble ammonium polyphosphate APP based flame retardant, content accounts for 50-55%;
Blowing agent is melamine, and content accounts for 6-10%;
Carbon forming agent is pentaerythrite, and content accounts for 12-15%;
Color stuffing is anatase thpe white powder, and content accounts for 6-10%;
Binding agent is Silicone acrylic emulsion, and content accounts for 12-15%.
Described mixed liquor is mixed in proportion by above-mentioned material.
It coats above-mentioned mixed liquor at Ji Bushang.
The processing technology of low-smoke bittern-free highly fire-proof band, carry out according to following steps:
1) adopt pure glass-fiber-fabric: 45 two strands, warp thread, density has 12-16 stock in 1 centimeter; Weft yarn 30 sub-threads or 45 bifilar, density has 12-14 root in 1 centimeter, above-mentioned pure glass-fiber-fabric be impregnated in fire prevention mixed liquor in, coated weight is 50-100g/m
2;
2) then 150-180 DEG C of oven dry, last rolling is cut and is formed.
The processing technology of low-smoke bittern-free highly fire-proof band, carry out according to following steps:
1) adopt glass and polyester filament blended cloth: warp thread 55D-75D polyester filament, density is 30-46 root in 1 centimeter; Weft yarn 45 two bursts of glass fibre yarn density have 10-16 root in 1 centimeter; Be impregnated in by above-mentioned pure blended cloth in fire prevention mixed liquor, coated weight is 50-100g/m
2;
2) then 150-180 DEG C of oven dry, last rolling is cut and is formed.
The processing technology of low-smoke bittern-free highly fire-proof band, carry out according to following steps:
1) pure terylene base cloth is adopted: longitudinal pulling force intensity > 120N/cm, grammes per square metre is at 50-150g/m
2; Be impregnated in by above-mentioned pure terylene base cloth in fire prevention mixed liquor, coated weight is 50-100g/m
2;
2) then 150-180 DEG C of oven dry, last rolling is cut and is formed.
The present invention is coated in fireproof paint on protected base material under high temperature or flame interaction, and the violent expanded charred foaming of coating, forms the spongiform carbonaceous layer do not fired of larger than former coating tens times, be full of not active gas in foam, produces effect of heat insulation.
This charring layer is good insulator, breaks off the direct heating of flame to ground, effectively stops heat to the transmission of ground, and can make the temperature that protected base material keeps lower within the regular hour; The chemical actions such as the decomposition of the physical change such as softening, melting, expansion of coating and polymer, filler, auxiliary agent in addition, evaporation and charing will absorb amount of heat, reduction ignition temperature and flame propagation velocity; The non-flammable gases that the acid source such as the phosphate of expanded foamed system and ammonium polyphosphate flame retardant decomposites in addition can water down the concentration of oxygen, forms carbonaceous insulated foam coating, closes protected base material, stop its ignition.
On the one hand phosphorus and oxygen and hydrocarbon combustion, generate the materials such as phosphide, carbon monoxide, steam, less than the reaction heat of charcoal direct generation carbon dioxide, to burn and fire-retardant so can slow down; Phosphorus forms pyrophosphoric acid to metaphosphoric acid when burning on the other hand, reacts as follows:
Metaphosphoric acid can aggregate into highly stable poly state, become combustible material protective layer and by oxygen-barrier.
