Problems solved by technology

When liquid or viscous paint is used in construction, construction personnel are required to have high coating technology, which consumes a lot of manpower and material resources; moreover, liquid or viscous paint is easy to splash during construction, especially in indoor construction. Protect furniture, electrical appliances and floors to avoid damage to indoor facilities; more importantly, liquid or viscous paints dry slowly
The powder coating requires special equipment when it is used in construction, it is not suitable for thin coating, only suitable for thick coating, and the baking temperature should be above 150 °C

preparation example Construction

[0029] The preparation method of the solid construction paint provided by the present embodiment may further comprise the steps:

[0030] Mix the excipient, humectant, and deionized water according to weight percentage, heat to a first predetermined temperature, and dissolve to obtain a first solution;

[0031] Adding a neutralizing agent to the first solution, raising the temperature to a second predetermined temperature, keeping the temperature for a predetermined time, so that the reaction is sufficient to obtain a second solution;

[0032] Add water-based paint to the second solution, and disperse evenly to obtain the third solution;

[0033] Pour the third solution into the mold, cool and shape to obtain the coating.

[0034] Preferably, the step is to mix the excipient, humectant, and deionized water by weight percentage, heat to a first predetermined temperature, and dissolve to obtain the first solution, and the first predetermined temperature is 60°C to 70°C;

[003...

preparation example 1

[0039] Mix 8% excipient by weight, 8% moisturizer by weight, and 21.28% deionized water by weight, heat to the first predetermined temperature of 60°C to 70°C, and dissolve; add 2% by weight % neutralizer, the temperature rises to 90°C-95°C, and the temperature is kept for 20-60 minutes to make the reaction fully; add 60.72% by weight of latex paint to obtain a uniformly dispersed solution; keep the temperature at 90°C-95°C , pour the solution into the mold, cool and shape to get solid interior wall latex paint. Herein, the weight percentage refers to the weight percentage of the raw material components and the solid coating, such as the weight percentage of stearic acid and the solid coating.

[0040] The latex paint can be any known latex paint in the art. But in this embodiment, the latex paint preferably includes the following components: 1.5 parts of propylene glycol, 0.2 parts of wetting agent, 1.5 parts of dispersant, 0.1 part of bactericide, 0.3 part of defoamer, 0.1 ...

preparation example 2

[0042] Mix 8% by weight excipient and 8% by weight humectant, heat to the first predetermined temperature of 60°C to 70°C, dissolve; add 2% by weight neutralizer, and raise the temperature to 90°C ℃~95℃, keep warm for 20 minutes to 60 minutes to make the reaction fully; add water-based industrial paint with a weight percentage of 82% to obtain a uniformly dispersed solution; keep the temperature at 90℃~95℃, pour the solution into the abrasive tool, Cool and form to obtain a solid water-based high-gloss white finish.

[0043] The water-based industrial paint can be any known water-based industrial paint in the art. But in this embodiment, the water-based industrial paint preferably includes the following components: 66 parts of water-based polyurethane dispersion, 0.6 part of 20% triethylamine, and 15.4 parts of titanium dioxide.

Abstract

The invention provides solid construction paint and a preparation method thereof. The construction paint comprises the following components in percentage by weight: 50-82% of a water-based paint, 2-10% of an excipient, 1-10% of a humectant, 1-5% of a neutralizer, and 0-40.5% of deionized water. The preparation method of the construction paint comprises the following steps: mixing and dissolving the excipient, the humectant and the deionized water so as to obtain a first solution; adding the neutralizer into the first solution, and heating the obtained mixture so as to fully react, thereby obtaining a second solution; adding the water-based paint into the second solution, uniformly dispersing the water-based paint so as to obtain a third solution; and pouring the third solution into a grinding tool to carry out cooling forming, thereby obtaining the paint. The paint provided by the invention is a solid paint, and when the paint is used in construction, paint splashing is not caused, so that indoor facilities are not required to be covered, thereby saving the construction time and reducing manpower and material resources; the paint is short in drying time. When the paint is used in construction, no professional device is required, thereby reducing the construction cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to solid construction coatings; in addition, the invention also relates to a preparation method of solid construction coatings. Background technique [0002] Coatings are materials that can be applied to the surface of an object to be coated and form a firmly adherent continuous film. It can be inorganic, such as copper plating, nickel plating, zinc plating, etc.; it can also be organic, such as most organic polymer materials. Organic coatings have become a major component of today's coatings market. In the related art, the form of the paint is liquid, viscous, or powder. When liquid or viscous paint is used in construction, construction personnel are required to have high coating technology, which consumes a lot of manpower and material resources; moreover, liquid or viscous paint is easy to splash during construction, especially in indoor construction. Protect furniture, elect...
