Problems solved by technology

[0003] The water-based paint for interior walls has also exposed some shortcomings during the use process. The main component of water-based paint is water. The viscosity of the newly manufactured water-based paint is extremely low. It needs to be thickened with a thickener according to the production standard before it can be produced and used. Although the thickener can significantly improve the performance of the coating, some thickeners need to adjust the pH value to achieve the thickening effect. Studies have also shown that the relative molecular weight of the thickener increases, and the splash performance of the coating also increases relatively, especially cellulose Thickener-like thickeners are prone to splash due to their large relative molecular weight. At the same time, due to the good hydrophilicity of cellulose, they will also reduce the water resistance of coatings. Therefore, it is necessary to improve the formulation of existing water-based coatings. Reduce the proportion of thickener while coating, so as to overcome the shortcomings of the prior art

Embodiment 1

[0022] This embodiment specifically provides a water-based coating for interior walls, which includes 260-380 kg of okra mucus, 20-50 kg of hollow microspheres, 12-17 kg of dispersant, 0.5-2 kg of wetting agent, and 0.5 kg of defoamer according to the weight in kg. -2kg, shell powder 40-140kg, heavy calcium 90-120kg, calcium hydroxide 285-360kg, water-based acrylic emulsion 60-80kg, insect repellent powder 3-5kg.

[0023] Among them, the dispersant is Disperbyk-190, the defoamer is at least one of byk-024, byk-022 and surfynol DF-40, and the insect repellent powder is made by mixing mugwort powder and lavender powder at a ratio of 1:1.

Embodiment 2

[0025] This embodiment provides a kind of preparation technology of interior wall water-based paint:

[0026] Choose fresh and disease-free okra, cut it into 1cm-long pieces, soak the okra in deionized water according to the ratio of material to liquid 5:3, let it stand for 5 minutes, then knead it while stirring, repeat 3 times, when finished Filter with a 100-mesh filter to remove impurities, and obtain the treated okra mucus, which is sealed and stored at a low temperature of 3°C; 260kg of okra mucus, 12kg of dispersant, 0.5kg of wetting agent, 0.5kg of defoamer, and 40kg of shell powder , 90kg of heavy calcium, 285kg of calcium hydroxide and 3kg of insect repellent powder were put into the ball mill in sequence according to the proportion and ground evenly, the grinding time was 30min, and finally filtered through 1200 mesh screen to obtain the mixed solution; Sequentially add to the container to disperse and stir evenly, then add 20kg of hollow microspheres and mix to com...

Embodiment 3

[0028] Choose fresh and disease-free okra, cut it into 1cm long pieces, soak the okra in deionized water according to the ratio of material to liquid 3:1, let it stand for 6 minutes, then knead it while stirring, repeat 3 times, when finished Filter with a 100-mesh filter screen to remove impurities, and obtain the treated okra mucus, which is sealed and preserved at a low temperature of 5°C; 327kg okra mucus, 15kg dispersant, 1kg wetting agent, 1kg defoamer, shell powder 96kg, weight Calcium 98kg, calcium hydroxide 319kg and insect repellent powder 4kg were put into the ball mill according to the proportion and grinded evenly, the grinding time was 45min, and finally filtered through 1200 mesh gauze to obtain the mixed solution; the mixed solution and 66kg water-based acrylic emulsion were added in turn Disperse and stir evenly in the container, then add 39kg of hollow microspheres and mix to complete the production of water-based paint for interior walls.

Abstract

The invention discloses water-based paint for an interior wall and a preparation method of the water-based paint. The ecological water-based paint is prepared from okra mucus, hollow microspheres, a dispersing agent, a wetting agent, a defoaming agent, shell powder, ground calcium carbonate, calcium hydroxide, water-based acrylic emulsion and insect expelling powder. Compared with an unimproved formula (I)according to the invention, the water-based paint has certain viscosity even without a thickener, and after being applied to the interior wall, the defect that the paint splashes easily due to addition of a thickener in the prior art is overcome; meanwhile, the insect expelling powder and the hollow microspheres are added into the formula, so that the interior wall coated with the water-based paint has insect expelling and heat insulation effects, and the water-based paint has wide practicability in the technical field of water-based paints.

Description

technical field [0001] The present invention mainly relates to the technical field of architectural coatings, in particular, the present invention relates to the technical field of an environmentally friendly coating and its preparation. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to the importance of green environmental protection to human health. In order to meet people's needs, our country has begun to vigorously carry out environmental protection. consciousness. Traditional solvent-based coatings will produce a large amount of organic volatiles in the process of manufacture and use, which not only poses hazards to human health, but also pollutes the environment. With the strengthening of people's awareness of environmental protection, many new green and environmentally friendly coatings have been developed, and water-based coatings are one of them. Water-based coatings have many advantages. They can s...
