Abstract
The invention provides a thick steel structure fire-resistant paint which is composed of high-alumina cement, bentonite, light calcium carbonate, meerschaum, expanded vermiculite, mica, expanded perlite, glass fiber and the like. In the construction process, the thick steel structure fire-resistant paint is proportionally and uniformly mixed with water glass and is usable at once. The fire-resistant paint has the characteristics of high water resistance, high seepage resistance, high impact resistance, high fire resistance, high mildew resistance, no toxicity or harm, long service life and the like. The fire-resistant paint is simple in processing technique and convenient for construction, and can greatly lower the production cost of the enterprise.
Description
Technical field
The invention belongs to frie retardant coating technical field, particularly a kind of thicker steel structure fire-proof paint.
Background technology
Along with the development of process of industrialization, especially in the middle of the construction of large-and-medium size cities, steel construction is with its superiority of constructing quickly and easily, become a very important Application in Building material, steel as metal material builds to be established, and is applied to the places such as Standard Factory Room, large-scale stadium, airport, bridge, multi-storied garage more.But the fire performance of steel construction and can not show a candle to brick mix structure, the critical temperature of steel is 540 DEG C, reaches this temperature, about its supporting capacity will reduce half.In general fire, about 15min can reach this temperature, thus causes caving in of buildings.This characteristic determines steel construction must take corresponding measures for the prevention of fire.Usual meeting at steel structure surface brushing frie retardant coating to ensure its fire performance.
Day by day perfect at environmental regulation, today of people's environmental pollution and health of human body pay attention to day by day, the use of the solvent-borne type frie retardant coating that content of volatile organic compound is very high is subject to more and more stricter restriction.To steel structure fire-proof paint require also more and more higher, sum up get up to steel structure fire-proof paint performance requriements mainly concentrate some: the first, good fire performance; The second, adhesive property is high, is convenient to spraying, easy construction; 3rd, good water-fast anti-permeability performance; 4th, do not produce toxic smog, good environmental protection; 5th, complete processing is easy, and cost is low; 6th, long service life, is convenient to change coating simultaneously; 7th, shock-resistant, the fire requirement with blast operating mode can be adapted to; 8th, other ilities be had, as: the performances such as decorate properties, sound absorption, mildew-resistant.But fireproofing paint for steel structure of the prior art only focuses on the index such as fire resistance, adhesive property often, and the environmental-protecting performance, shock-resistance, impervious water resistance, fungicidal properties etc. of coating is not often paid close attention to.Now commercially occur that more coating is mostly slim or ultrathin, better use extensively because it is ornamental; But it easily produces the obnoxious flavoures such as smog when fire occurs, thus contaminate environment.
Summary of the invention
The object of the present invention is to provide a kind of thicker steel structure fire-proof paint and complete processing thereof, this frie retardant coating have water-fast, impervious, shock-resistant, fire-resistant, fungicidal properties is high, and has the features such as nontoxic, long service life.Its complete processing is simple, easy construction, can greatly reduce enterprise's production cost
A kind of thicker steel structure fire-proof paint, be made up of powder and binding agent, described powder and binding agent ratio are 1:1-1:1.5, count by weight proportion;
Described powder comprises following one-tenth and is grouped into, and counts by weight:
High-alumina cement 40-50 part
Wilkinite 10-20 part
Light calcium carbonate 10-20 part

Above-mentioned a kind of thicker steel structure fire-proof paint, wherein, binding agent is the sodium silicate of modification or the one of potash water glass.
Above-mentioned a kind of thicker steel structure fire-proof paint, wherein, the length of glass fibre is 5-10mm.
Above-mentioned a kind of thicker steel structure fire-proof paint, wherein, its working method is:
A) preparation
Add in agravic blender by high-alumina cement, wilkinite, pearlstone, glass fibre, open fly cutter, to avoid occurring bonding, prevent from stirring inequality, churning time is 5 minutes, closes fly cutter.And then adding sepiolite, expanded vermiculite, mica, pearlstone continuation stirring, churning time 5 minutes, finally measures pack.
B) coating preparation
Powder and binding agent are joined in proportion in forced mixer, stir and can use for 3 minutes, the coating be stirred must be finished within half an hour.
Compared with prior art, beneficial effect of the present invention is:
1, owing to have employed inorganic raw material, coating is nontoxic, harmless, can not to environment.
2, the use of modified water glass, makes product have better cohesive strength and water tolerance.
3, use raw material light weight, heat insulation, thermal conductivity is little, play in coating heat insulation, low-density effect is fallen.
4, the glass fibre added, greatly improves the resistance to cleavage of steel structure fire-proof paint, considerably increases product toughness, improve the shock-resistance of steel structure fire-proof paint.
Embodiment
Below by way of specific embodiment, the specific embodiment of the present invention is described in further detail.
Embodiment 1
A kind of thicker steel structure fire-proof paint, its preparation method is as follows: add in agravic blender by 40 parts of high-alumina cements, 15 parts of wilkinites, 15 parts of light calcium carbonates, 1 part of glass fibre, open fly cutter, to avoid occurring bonding, prevent from stirring inequality, churning time is 5 minutes, closes fly cutter.And then adding 10 parts of sepiolites, 5 parts of expanded vermiculites, 5 parts of micas, 10 parts of pearlstones continuation stirrings, churning time 5 minutes, finally measures pack.During construction, powder and water glass are added in forced mixer in proportion and stirs, can use.The coating be stirred must be finished within half an hour.
Here description of the invention and application is illustrative, not wants by scope restriction of the present invention in the above-described embodiments, and therefore, the present invention is not by the restriction of the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
