Problems solved by technology

[0003] Patent CN 1045271 discloses a heat-insulating coating and its preparation process, which uses materials such as ceramic cotton and sepiolite as aggregates, and has a good flame-retardant effect. However, the problem of this invention is that the coating is thicker than 3mm. And the reflection effect is poor, and the heat insulation and energy saving effect is poor
There are many problems in the coating prepared by this method, the foaming agent is used, which makes the coating have an open-pore structure, which leads to the increase of water absorption during the condensation of water vapor, which leads to poor thermal insulation performance
and the use of organic solvents poses a fire risk during preparation and use

preparation example Construction

[0060] A kind of preparation method of water-based flame-retardant energy-saving anticorrosion coating of the present invention, concrete operation steps are as follows:

[0061] 1) Weigh 4.00-30.00 wt% rubber aqueous dispersion latex, 32.00-56.00 wt% elastic acrylic dispersion, 0.30-0.35 wt% defoamer, 0.20-0.25 wt% polyhexamethylene Add guanidine phosphate into the dispersion tank and disperse at low speed for 5-10 minutes to obtain a homogeneous mixture I;

[0062] 2) Weigh 1.00-5.00 wt% of fluoroplastics, 5.00-7.00 wt% of decabromodiphenyl ether, 5.00 wt% of magnesium hydroxide, 1.00-2.00 wt% of titanium dioxide, 1.00-2.00 wt% of Ceramic fiber, under low-speed stirring, add to the mixed solution I in turn, and then disperse at a high speed for 10-15 minutes, until the mixture is evenly mixed, and the mixture II is obtained;

[0063] 3) Add 14.00-35.00 wt% of 3M hollow glass microsphere mixture (the weight ratio of 600 mesh glass microspheres and glass microspheres with a p...

Embodiment 1

[0067] 1) Weigh 4.00 parts of rubber water dispersion latex, 56.00 parts of elastic acrylic dispersion, 0.35 parts of defoamer BYK-0340, and 0.25 parts of polyhexamethylene guanidine phosphate into the dispersion tank, and disperse at a low speed of 300-500 r / min 5-10 minutes to obtain a homogeneous mixture I;

[0068] 2) Under stirring at a low speed of 300-500 r / min, add 5.00 parts of fluoroplastic (nano polytetrafluoroethylene), 5.00 parts of decabromodiphenyl ether, 5.00 parts of magnesium hydroxide, 1.00 parts of titanium dioxide, and 1.40 parts of ceramic fiber to mix In liquid I, disperse at a high speed of 1000-1500 r / min for 10-15 minutes, until the mixture is uniform, and the mixture II is obtained;

Abstract

The invention relates to a water-based flame-retardant energy-saving anticorrosive coating comprising the following components in percentage by mass: 4.00 to 30.00 wt% of rubber aqueous dispersion latex, 32.00 to 56.00 wt% of an elastic acrylic acid dispersion body, 14.00% to 35.00% of 3M hollow glass beads, 1.00 to 5.00 wt% of fluoroplastic, 5.00 to 7.00 wt% of decabromodiphenyl ether, 5.00 wt% of magnesium hydroxide, 1.00 to 2.00 wt% of titanium dioxide, 1.00 to 2.00 wt% of ceramic fibers, 0.20 to 0.25 wt% of polyhexamethylene guanidine phosphate, and 0.30 to 0.35 wt% of a defoaming agent. The coating can be used for heat insulation, energy conservation, flame retardance, sterilization and corrosion prevention of surfaces with various properties and shapes of industrial buildings, equipment facilities, pipelines and the like, and has the advantages of heat insulation, heat preservation, good heat stability (as high as 300 DEG C), good flame retardance and reliable corrosion prevention and sterilization performance.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a water-based flame-retardant and energy-saving anti-corrosion coating and a preparation method thereof. Background technique [0002] The ceramic heat-insulating and anti-corrosion coating disclosed in patent CN 1807530A uses acrylate copolymer resin emulsion, colloidal silicon dioxide as the matrix, and ceramic powder as the main filler, which can efficiently reflect solar heat and is popularized for oil storage in the petrochemical industry Tanks, liquefied gas tanks, etc. Although the coating of this invention has a good solar reflectance, it does not reflect the thermal insulation coefficient in terms of mechanism and data, and the long-term thermal insulation effect needs to be verified, and the formula design does not consider the flame retardant effect when used in oil tank farms. [0003] Patent CN 1045271 discloses a heat-insulating coating and its prep...
