Preferably, the modified calcium carbonate that also contains 0.5-3% in described external coating.
A fire retardant treatment process for flame retardant type magic tape, is characterized in that comprising the following steps:
1. soak: magic tape is being soaked to 60-100 minute containing in the solution of organic phosphorus flame retardant, and solution PH is 3.5-4, and treatment temperature is 50-70 ℃;
2. dry: the magic tape after immersion was 8-12 minute/circle by the first steam roller drying rate in 1 hour, and bake out temperature is 140-155 ℃;
3. gluing: the magic tape surface-coated polyurethane colloidal sol after oven dry;
4. solidify: the second steam roller processing speed that the magic tape after gluing is 150-165 ℃ by vapor (steam) temperature is 8-12 minute/circle;
5. maturation: the 3rd steam roller processing speed that the magic tape after solidifying is 140-155 ℃ by vapor (steam) temperature is 8-12 minute/circle, can obtain finished product after maturation finishes.
In some case study on implementation, in described soaking step, solution phosphorus content used is 12-20%.
In some case study on implementation, described organic phosphorus flame retardant has a kind of or many kinds of substance wherein in phosphate, phosphonate ester, phosphite ester, organophosphorated salt, phosphoric acid, phosphorus-containing polyol.
In some case study on implementation, the sol formulation of described gluing step is:
Polyurethane resin 25-30%
Acetone 35-40%
Ethyl acetate 35-40%.
Preferably, the sol formulation of described gluing step is:
Compared to existing technology, the flame retardant type magic tape of the invention and fire retardant treatment process beneficial effect thereof are:
1, undercoating can provide fire-resisting protection for magic tape, and external coating can not only make magic tape have good elasticity, and has certain heat-insulating flame-retardant effect.
While decomposing when 2, organic phosphorus flame retardant is heated, can resolve into phosphorus and oxyacid, the charing of oxyacid energy catalytic hydroxylation compound, prevents that oxygen from contacting with fiber, reduce the mass loss of material, and can not distribute toxic gas, and little to ambient influnence, be applicable to sealing occasion and use.
3, in external coating, filling-modified calcium carbonate can improve the strength of coating under normal condition, and can further improve the fire resistance of external coating.
4, the curing maturation of the oven dry of fire retardant, colloidal sol all adopts steam roller to complete, and process is easy to control continuously.
5, the oven dry of colloidal sol is divided into solidifying and two steps of maturation of condition difference and continued operation, and the external coating of synthesis type plays better flame retardant effect.
