Abstract
The present invention proposes a kind of make with inorganic materials, expanding fire-proof paint that layering is applied to the steel construction surface, belongs to the frie retardant coating field.The invention is characterized in: coating is made up of high temperature foaming layer, low-temp foaming layer, sealing coat, by following precedence, divides four layers and is applied to steel surface: high temperature foaming layer, sealing coat, low-temp foaming layer and sealing coat.All material is all made with cheap inorganic materials, and the echelon foaming forms compound coating, and do not produce toxic gas in the back-fire relief process, and fire endurance surpasses 60 minutes, can apply for the modern building of various steel construction, as the flameproof protection measure.
Description
The present invention proposes a kind of make with inorganic materials, expanding fire-proof paint that layering is applied to the steel construction surface, belongs to the frie retardant coating technical field.
Before the present invention proposes, disclose two kinds of inorganic expansion type frie retardant coatings in U.S. Pat-488057: a kind of is to mix aluminium powder in the water glass, and another kind is to mix silicon carbide and silicon carbide whisker in the water glass.Its using method is: the former is as binding agent and sealing coat, and the latter is coated in the surface of aluminum or aluminum alloy successively as foaming layer, in order to fire prevention.There are three shortcomings in the above-mentioned fireproofing that is composited by two kinds of coating: (1) fire endurance has only 30 minutes; (2) used aluminium powder, silicon carbide whisker are relatively more expensive; (3) use range is little, only is applicable to aluminium and aluminium alloy, is not suitable for a large amount of steel construction that use of modern society.
The objective of the invention is to overcome the shortcoming that exists in the above-mentioned prior art, adopt the inorganic materials development a kind of be applicable to steel construction, fire endurance is long, coating processes is simple, do not produce the frie retardant coating of toxic gas during foaming.
The object of the present invention is achieved like this: the surface at steel construction applies four coatings successively: the high temperature foaming layer that produces nontoxic gas during (1) high temperature (more than 500 ℃); (2) apply one deck sealing coat then; (3) can produce the low-temp foaming layer of nontoxic gas again during coat one deck low temperature (below 500 ℃); (4) apply one deck sealing coat at last again.Thus, formed a kind of compound coating of forming by four coatings.The fire-proof function of this compound coating during fire finished like this: at the fire initial stage, after the low-temp foaming layer is heated, about 200 ℃, produce nontoxic gas, and at first foaming, the performance heat-blocking action, the intensification trend of slowing down steel construction is used for the back-fire relief in early stage.When flame continued to be warming up to more than 800 ℃, along with the molten of low-temp foaming layer contracts, the high temperature foaming layer began to produce nontoxic gas, bubbled, and formed fine and close thermofin, continued back-fire relief.Be positioned at high low temperature foaming layer sealing coat middle and low-temp foaming layer outside and adopt same material to make, do not foam, its effect is heat insulation and suppresses the excess foaming of foaming layer.
The present invention's advantage compared with prior art is:
1, fire endurance was long, above 60 minutes;
2, coating processes is simple, easily brushing;
3, coating ultimate compression strength height, in case of necessity, the workmen can stand on the coating and brush;
4, the used coating of each coating is all nonflammable, free from extraneous odour, and the workmen does not need special protective device;
5, in the back-fire relief process, do not discharge toxic gas;
6, sticking power is better between coating and the steel construction;
7, the prices of raw and semifnished materials are cheap.
Introduce embodiments of the invention in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention, and among the figure, 1 is steel construction, and 2 is the high temperature foaming layer, and 3 is sealing coat, and 4 is the low-temp foaming layer, and 5 is sealing coat.
1, the composition of high temperature foaming layer and manufacture method are as follows:
A, composition are: totally four kinds of water glass, glass powder, pearlstone and carbon blacks, the weight ratio between them is followed successively by 50: 30: 12～24: 0.1～3.0.
B, manufacture method are: glass powder (fineness 〉=180～300 orders), swelling perlite powder, carbon black with porphyrize according to the above ratio, mix with ball milling, make the high temperature foaming pellet, join then in water glass (modulus M 〉=30) base-material, stir, high temperature foaming layer coating.
2, the composition of low-temp foaming coating and manufacture method thereof:
A, composition are: water glass (modulus M＞3.0), white carbon black (purity 〉=88%), sodium hydroxid (or potassium hydroxide, yellow soda ash, salt of wormwood, purity 〉=98%) titanium dioxide (various crystal formations all can) is successively by following weight ratio preparation: 100: 9～24: 1～10: 0.5～0.8.
B, manufacture method: according to the above ratio, earlier white carbon black and titanium dioxide are mixed, obtain low-temp foaming layer powder; Again water glass and sodium hydroxide (or potassium hydroxide, yellow soda ash, salt of wormwood) are mixed, obtain mixed liquid; At last, the low-temp foaming powder of gained and mixed liquid are mixed, stir, just obtain the low-temp foaming coating.
3, sealing coat system component and manufacture method thereof:
A, moiety are: water glass (modulus M 〉=3.0), high-al clay (fineness 325 orders), talcum powder (fineness 325 orders), prepare by following weight ratio: 20～30: 25: 5.
B, manufacture method are: by above-mentioned weight ratio, high-al clay, talcum powder poured in the water glass, stir.
The composition of composite coating and constructional method:
Be brushed to above-mentioned three kinds of materials on the surface of steel construction by following precedence: high temperature foaming layer, sealing coat, low-temp foaming layer, sealing coat.The consumption of coating and coat-thickness should reach following requirement: high-rise foaming layer: the coating consumption is 6.0～6.2 kilograms/meter
2, wet coat-thickness is 2.4～2.5 millimeters; Sealing coat: the coating consumption is 0.8～0.9 kilogram/meter
