Abstract
The invention discloses water-based fire protection finishing coat. The water-based fire protection finishing coat is prepared from 30-40% of water-based polyurethane emulsion, 22-28% of a mixture of polymer-coated nanometer magnesium hydroxide and ammonium polyphosphate which are in a weight ratio of 1:1, 20-25% of deionized water, 8-12% of filler, 5-7% of aids, 0.2-0.5% of a defoaming agent, 0.1-0.5% of preservative and 0.5-0.9% of a thickening agent. The water-based fire protection finishing coat has good fire protection performance.
Description
Technical field
The present invention relates to water-based fireproof finish paint.
Background technology
In each field, widely, as on exterior wall, industrial warehouse, chemical industry, oil, food service industry class basin and pipe surface, the buildingss such as factory building, modernization plant, freezer, house owed by a citizen, office building are first-class in the application of coating.
Tradition is all the coating for organic solvent, and the contaminative of this coating is serious, therefore, now everybody big area bring into use water-borne coatings, and for exterior coating, need the wherein important technological problems solved to be fire prevention, but its fire resistance of existing water-borne coatings is all not good enough.
Summary of the invention
The object of this invention is to provide the water-based fireproof finish paint that a kind of fire resistance is good.
For achieving the above object, water-based fireproof finish paint, is made up of following raw material according to weight percent meter:
Aqueous polyurethane emulsion 30%-40%
Weight ratio is the nano-sized magnesium hydroxide of the polymer overmold of 1:1 and the mixture 22%-28% of ammonium polyphosphate
Deionized water 20%-25%
Filler 8%-12%
Auxiliary agent 5%-7%
Defoamer 0.2%-0.5%
Sanitas 0.1%-0.5%
Thickening material 0.5%-0.9%.
Further, the weight percent of each raw material is:
Aqueous polyurethane emulsion 35%
Weight ratio is the nano-sized magnesium hydroxide of the polymer overmold of 1:1 and the mixture 25% of ammonium polyphosphate
Deionized water 22.6%
Filler 10%
Auxiliary agent 6%
Defoamer 0.4%
Sanitas 0.3%
Thickening material 0.7%.
Further, filler is the one in talcum powder, dicalcium powder, kaolin, process white.
Further, described auxiliary agent is film coalescence aid, and described film coalescence aid is alcohol ether solvent or the cruel kind solvent of alcohol.
Further, described defoamer is polysiloxane-polyether copolymer, and described sanitas is nitrite, and described thickening material is one or both in association type polyurethane thickener.
The invention has the beneficial effects as follows: ammonium polyphosphate is nonpoisonous and tasteless, do not produce etchant gas, water absorbability is little, thermostability is high, there is good fire resistance, but when it uses together with the nano-sized magnesium hydroxide of polymer overmold, both create mutual synergy, thus further increase fire resistance; Meanwhile, coating of the present invention can form that sticking power is 0 grade, hardness is greater than 1H, the coating that water tolerance is greater than 250 hours on substrate surface.
