Abstract
The invention discloses a fireproof coating for steel structures and belongs to the technical field of chemical industry. The fireproof coating consists of the following components in parts by weight: 15-25 parts of epoxy resin, 7-13 parts of acrylic resin, 3.7-4.5 parts of No. 200 gasoline, 4-6 parts of dimethyl benzene, 5-7 parts of butyl acetate, 0.5-0.9 part of fumed silica, 0.1-0.3 part of a dispersant, 6-8 parts of pentaerythritol, 5-10 parts of acetone, 16-18 parts of ammonium polyphosphate, 5-8 parts of melamine, 10-14 parts of antimony trioxide and 2-5 parts of titanium dioxide powder. The fireproof coating disclosed by the invention has good mechanical and physicochemical performance and can form a good foam heat insulating layer in a fire, and the foam layer does not drop even at a high temperature; the fireproof coating disclosed by the invention is good in metal corrosion resistance and good in appearance decoration.
Description
Technical field
the present invention relates to chemical technology field, specifically a kind of steel structure fire-proof paint.
Background technology
Because steel construction has that intensity is high, load-bearing ability is strong,, member manufacture little from light weight, duty volume with easy for installation, save many advantages such as timber, in being therefore applied to more and more widely build.Along with the development of China's building cause, various buildings are emerged rapidly in large numbersBamboo shoots after a spring rain, increasing, and all departments also increase day by day to the requirement of using steel structure fire-proof paint to make steel flameproof protection.Steel are as material of construction in the defect that exists again some to be difficult to avoid aspect fire prevention, and its mechanical property is understood the rising of Yin Wendu and sharply declined.Steel construction is owing to overcoming in actual applications the deficiency of fire prevention aspect, the processing of must preventing fires, and its object is exactly the fire endurance of steel construction to be brought up to the limit range of design specifications.Outside steel construction, outside forming, to be bundled into be the common method that realizes steel structure fireproofing to sprayed fire proofing coating.Prior art steel structure fire-proof paint does not reach requirement.
Summary of the invention
The object of the present invention is to provide a kind of steel structure fire-proof paint.
Object of the present invention can be achieved through the following technical solutions:
A kind of steel structure fire-proof paint, it is characterized in that, by weight, composed of the following components: epoxy resin 15-25 part, acrylic resin 7-13 part, No. 200 gasoline 3.7-4.5 parts, dimethylbenzene 4-6 part, N-BUTYL ACETATE 5-7 part, aerosil 0.5-0.9 part, dispersion agent 0.1-0.3 part, tetramethylolmethane 6-8 part, acetone 5-10 part, ammonium polyphosphate 16-18 part, trimeric cyanamide 5-8 part, antimonous oxide 10-14 part, titanium dioxide 2-5 part.
The present invention by weight, composed of the following components: 20 parts of epoxy resin, 4.1 parts, 9.5 parts, No. 200 gasoline of acrylic resin, 5 parts of dimethylbenzene, 6 parts of N-BUTYL ACETATEs, 0.7 part of aerosil, 0.2 part of dispersion agent, 7 parts of tetramethylolmethanes, 7.6 parts, acetone, 17 parts of ammonium polyphosphates, 6.5 parts of trimeric cyanamides, 12 parts of antimonous oxides, 3.5 parts of titanium dioxides.
Dispersion agent of the present invention is high molecular urethane.
Beneficial effect of the present invention: frie retardant coating of the present invention has good mechanical physicochemical property, forms good insulated foam coating when being subject to fire, and foaming layer does not come off yet under hot conditions, the resistance to metallic corrosion performance of frie retardant coating of the present invention is good, and decorative appearance is good.
