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] The preparation method of a water-based flame-retardant, energy-saving and anti-corrosion coating of the present invention has the following specific operation steps:

[0061] 1) Weigh 4.00-30.00 wt% rubber water dispersion latex, 32.00-56.00 wt% elastic acrylic dispersion, 0.30-0.35 wt% defoamer, 0.20-0.25 wt% polyhexamethylene by mass percentage The guanidine phosphate is added to the dispersion tank, and dispersed at a low speed for 5-10 minutes to obtain a uniform mixed solution I;

[0062] 2) Weigh 1.00-5.00 wt% fluoroplastic, 5.00-7.00 wt% decabromodiphenyl ether, 5.00 wt% magnesium hydroxide, 1.00-2.00 wt% titanium dioxide, 1.00-2.00 wt% The ceramic fibers are added to the mixed solution I in turn under low-speed stirring, and then dispersed at a high speed for 10-15 minutes until the mixing is uniform to obtain the mixture II;

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

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 uniform mixed solution I;

[0068] 2) Under stirring at a low speed of 300-500 r / min, 5.00 parts of fluoroplastics (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 fibers were added and mixed. In liquid I, disperse at a high speed of 1000-1500 r / min for 10-15 minutes, until the mixture is uniform, and obtain mixture II;

[0069] 3) Under the condition of stirring and dispersing at a low speed of 300-500 r / min, add 22.00 parts of the hollow glass microsphere mixture (the weight ratio of 600 mesh glass microspheres to glass microspheres with a particle size of 20-120 μm is 3:2) into...

Abstract

A water-based flame-retardant, energy-saving and anti-corrosion coating, comprising the following components by mass percentage: 4.00-30.00 wt% of rubber water dispersion latex; 32.00-56.00 wt% of elastic acrylic dispersion; 14.00-35.00% of 3M hollow glass microspheres; fluoroplastics 1.00-5.00 wt%; Decabromodiphenyl ether 5.00-7.00 wt%; Magnesium hydroxide 5.00 wt%; Titanium dioxide 1.00-2.00 wt%; Ceramic fiber 1.00-2.00 wt%; Polyhexamethyleneguanidine phosphate 0.20-0.25 wt%; defoamer 0.30‑0.35 wt%. It can be used for thermal insulation, energy saving, flame retardant, sterilization and anti-corrosion of surfaces of various properties and shapes such as industrial buildings, equipment facilities, pipelines, etc. And has reliable antiseptic and bactericidal properties.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a water-based flame-retardant energy-saving anti-corrosion coating and a preparation method thereof. Background technique [0002] The ceramic heat-insulating and anti-corrosion coating disclosed in the patent CN 1807530A is based on acrylate copolymer resin emulsion, colloidal silicon dioxide as the matrix, and ceramic powder as the main filler, which can reflect the solar heat efficiently, and is popularized for oil storage in the petrochemical industry. Tanks, LPG tanks, etc. Although the coating of the invention has good solar reflectivity, it does not reflect the thermal insulation coefficient from the 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 the oil tank farm. [0003] Patent CN 1045271 discloses a thermal insulation coating and its ...
