Problems solved by technology

First of all, this type of product contains a certain amount of harmful substances such as formaldehyde and volatile organic compounds (VOC); secondly, the color retention is poor. Generally, after half a year to one year of painting, there will be obvious fading and discoloration, and it will also emit an unpleasant smell. odor; again, it is lacking in water resistance, stain resistance, etc., and it is inconvenient to paint
[0003] At present, seaweed mud mineral paint is relatively rare in the market, and has not attracted enough attention from consumers, and the cost is too high. Therefore, it is urgent to develop an environmentally friendly seaweed mud mineral wall paint with better performance and lower cost.

preparation example Construction

[0042] Preparation of decolorized seaweed mud powder:

[0043] ① Install a double-leaf agitator in the dispersion tank, put activated carbon at the bottom of the dispersion tank, and install a 100-mesh screen in the middle of the dispersion tank;

[0044] ②Secondly, pour 1 / 2 water into the dispersion tank, pour the seaweed mud from the deep sea of ​​Hokkaido, Japan into the upper part of the dispersion tank (above the screen), start the double-bladed mixer, stir the seaweed mud or stir the seaweed mud and activated carbon at the same time , After stirring for 4h, let stand for 24h.

[0045] ③Then turn on the water, and the seaweed mud on the screen is decolorized seaweed mud powder. Before use, it can be dried to remove moisture, and the following examples all adopt the decolorized seaweed mud powder after drying.

Embodiment 1

[0047]Firstly, add 250.16kg of water, 1.00kg of ephedrine, 5.03kg of dispersant SN5040, 1.58kg of wetting agent CF-10, and 0.98kg of defoamer NXZ into the reaction kettle in sequence. Disperse (5~25)min, then add 150.00kg decolorized seaweed mud powder, 201.71kg R-902 titanium dioxide, 50.00kg talc powder, disperse (20~40)min at the speed (1000~1500)r / min, pass Sanding until the fineness of the material is ≤50μm; after sanding until the fineness of the material is ≤50μm, add 229.34kg of pure acrylic emulsion (ELASTENE TM (Erenda TM ) 3131NG), 40.61kg aloe vera plant glue, 14.21kg glycerin, 2.03kg fungicide ethanol (75%), 0.97kg defoamer NXZ, 0.91kg British Saul RS preservative, at a speed of (300-900) r / Disperse in min (10-30) min. Finally, use 9.84kg vegetable glue and 41.69kg water to adjust the viscosity, so that the viscosity is (100±5) KU at (25±1)°C, and a white flowing liquid is obtained after passing through a 200-mesh sieve, which is the invention product. Product ...

Embodiment 2

[0049] First add 232.34kg of water, 0.97kg of ephedrine, 4.92kg of dispersant SN5040, 1.37kg of wetting agent CF-10, and 1.02kg of defoamer NXZ into the reactor in sequence, disperse at a medium speed for 5-10min, and then add 163.51kg Decolorized seaweed mud powder, 219.64kg R-902 titanium dioxide, 48.93kg talcum powder, disperse at high speed for 10-15min, and then add 212.62kg of pure acrylic emulsion (ELASTENE TM (Erenda TM ) 3131NG), 37.41kg vegetable gum, 13.70kg glycerin, 1.86kg fungicide ethanol (75%), 0.95kg defoamer NXZ, 0.94kg fungicide RS, disperse at medium speed for 10-15min. Finally, adjust the viscosity with 11.63kg aloe vera plant glue and 40.58kg water, so that the viscosity is (100±5) KU at (25±1)°C. After passing through a 200-mesh sieve, a white flowing liquid is obtained, which is the invention product. See Table 1 for performance testing.

Abstract

The invention discloses an algae clay mineral environmentally-friendly inner wall coating, which is prepared from the following components in parts by weight: 310-360 parts of water, 0.8-3 parts of alkaloid, 2-8 parts of dispersant, 1-2 parts of wetting agent, 1-2 parts of defoaming agent, 100-200 parts of decolorized algae clay powder, 150-250 parts of titanium pigment, 20-60 parts of talcum powder, 20-30 parts of pure acrylic acid emulsion, 25-75 parts of vegetable gum, 10-15 parts of glycerin, 1-5 parts of 75 percent ethanol and 1-2 parts of disinfectant. The inner wall coating has the advantages of nontoxicity, harmlessness, convenience for constructing, extremely strong peculiar smell adsorbing function, capability of purifying indoor air, plump paint film, smooth handfeel, high air permeability, wall surface breathing function, capability of regulating indoor humidity environment, high alkali resistance, high water resistance, high chemical corrosion resistance, high erosion resistance, high heat resistance, high freezing resistance, high ageing resistance, high covering power, high adhesion and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings for interior decoration, and in particular relates to a seaweed mud mineral paint with excellent environmental performance. Background technique [0002] Most of the pigments and fillers and antifreezes used in traditional water-based paints are petrochemical raw materials, and the environmental protection performance of these products has many defects. First of all, this type of product contains a certain amount of harmful substances such as formaldehyde and volatile organic compounds (VOC); secondly, the color retention is poor. Generally, after half a year to one year of painting, there will be obvious fading and discoloration, and it will also emit an unpleasant smell. Odor; Again, it is lacking in water resistance, stain resistance, etc., and it is inconvenient to paint. [0003] At present, seaweed mud mineral paint is relatively rare in the market, and has not attracted enough attention f...
