preparation example Construction

[0031] The present invention also provides a method for preparing the above-mentioned high-temperature-resistant fireproof and heat-insulating coating, which includes: mixing silica sol and sodium silicate, adding methylphenyl silicone resin, then adding wetting agent and defoamer, stirring and mixing After uniformity, heat-insulating fillers are added to obtain high-temperature-resistant fire-proof and heat-insulating coatings.

[0032] Wherein, the contents and types of the silica sol, sodium silicate, methylphenyl silicone resin, wetting agent, defoamer and heat-insulating filler are the same as those described above, and will not be repeated here.

[0033] The present invention also provides an application of the above-mentioned high-temperature-resistant fire-proof and heat-insulating coating in heat preservation of equipment below 600°C.

[0034] The present invention also provides a method for using the above-mentioned high-temperature-resistant fire-proof and heat-insu...

Embodiment 1

[0038] First add quantitative silica sol and sodium silicate into the beaker, then add quantitative methylphenyl silicone resin while stirring, then add wetting agent and defoamer, after stirring evenly, add ceramic microspheres, glass microspheres in turn and rutile titanium dioxide. After being completely stirred evenly, a high-temperature-resistant fireproof and heat-insulating coating can be obtained.

[0039] The formula is: 20% methyl phenyl silicone resin, 40% sodium silicate, 15% silica sol, 1% wetting agent alkyl polyether, 0.05% defoamer, 5% ceramic microspheres, 15% glass microspheres , rutile titanium dioxide 3.95%.

Embodiment 2

[0041] The preparation method is the same as in Example 1, except that the formula is: 15% methylphenyl silicone resin, 40% sodium silicate, 20% silica sol, 1% wetting agent alkyl polyether, and 0.05% defoamer , ceramic microspheres 5%, glass microspheres 15%, rutile titanium dioxide 3.95%.

Abstract

The invention provides a high-temperature-resistant fireproof heat-insulating coating which comprises the following components in parts by weight: 10-30 parts of methyl phenyl silicone resin; 10-40 parts by weight of sodium silicate; 10-25 parts by weight of silica sol; 1-2 parts by weight of a wetting agent; 0.05 to 0.1 part by weight of a defoaming agent; and 13-30 parts by weight of a heat insulation filler. Compared with the prior art, the methyl phenyl silicone resin, the sodium silicate and the silica sol are mixed together to serve as a binder, the methyl phenyl silicone resin is good in adhesive force at high temperature but can be burnt, and the sodium silicate serving as an electrodeless binder has good fireproof performance; meanwhile, by adding the silica sol, the adhesive force of the adhesive and a base material can be obviously improved; the heat insulation filler is added, so that the heat preservation property, the weather resistance and the high temperature resistance of the coating can be further improved, and the coating is used for the surface of high-temperature equipment, can preserve heat and insulate heat and has fireproof performance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-temperature-resistant fireproof and heat-insulating coating and a preparation method thereof. Background technique [0002] With the continuous development of my country's modern industry, especially in metallurgy, petrochemical, energy, new materials and military industries, more and more high-temperature equipment and supporting facilities are used. However, metal materials are prone to contact with oxygen in the air in high-temperature environments. Oxidation reaction occurs and rust occurs, so that the metal material gradually loses its strength and leads to structural loss, which becomes a hidden danger of various accidents. Therefore, the surface of high-temperature equipment generally needs to be protected by coating with high-temperature resistant coatings to prevent oxidation and corrosion of metal materials and prolong the service life of high-tempera...
