Problems solved by technology

[0005] Water-based paints have also exposed some shortcomings in use. The main component of water-based paints is water. Due to the high evaporation heat of water, the volatilization speed is slow, which affects the drying speed.
Secondly, due to the high surface tension of water, it is not easy to infiltrate the substrate, and shrinkage cavities are prone to occur, and the cleanliness during the construction process and the cleanliness of the material surface are high, so it is difficult to form a complete paint film on the surface of the material

Embodiment 1

[0031] The present embodiment specifically provides an improved ecological water-based paint, which comprises 85-100 parts of water, 140-185 parts of coconut milk, 23-28 parts of aloe gel, 12-16 parts of corn silk, and 11 parts of dispersant according to parts by weight. -16 parts, 1-3 parts of wetting agent, 2-3 parts of defoamer, 20-70 parts of titanium dioxide, 80-150 parts of calcium hydroxide, 10 parts of wax emulsion.

[0032] Wherein, the dispersant is composed of stearylamide and higher alcohol, and the weight ratio is 2:1.

[0033] Wherein, the defoamer is composed of a silicone defoamer and a mineral oil defoamer in a weight ratio of 3-7.

Embodiment 2

[0035] The present embodiment provides a kind of preparation technology of improved ecological water-based paint:

[0036] First select fresh and disease-free coconuts, extract fresh coconut juice from them, and filter the extracted coconut juice with a filter mesh number of 80 mesh, and then use it for later use. Simultaneously screen and select the mildew-free and non-deteriorated corn silk of the current season. After cleaning, put it in a wall breaking machine to crush and break the wall for 3 minutes, then add water and let it settle naturally. After 25 minutes, the upper layer of liquid and the lower layer of sediment Separation, the lower precipitate is dried, ground into powder after drying, calcined at 90°C, and passed through a 200-mesh sieve for later use. Then add 85kg of water, 140kg of coconut juice, 23kg of aloe gel, 12kg of corn silk, 11kg of dispersant, and 1kg of wetting agent into the container of the disperser according to the proportion, start the disperse...

Embodiment 3

[0038]First select fresh and disease-free coconuts, extract fresh coconut juice from them, and filter the extracted coconut juice with a filter mesh number of 80 mesh, and then use it for later use. Simultaneously screen and select the mildew-free and non-deteriorated corn silk of the current season. After cleaning, put it into the wall breaking machine to crush and break the wall for 4 minutes, then add water and let it settle naturally. After 28 minutes, the upper liquid and the lower sediment Separation, the lower precipitate is dried, ground into powder after drying, calcined at 100°C, and passed through a 200-mesh sieve for later use. Then add 90kg of water, 150kg of coconut juice, 26kg of aloe vera gel, 14kg of corn silk, 15kg of dispersant, and 2.5kg of wetting agent into the container of the disperser in sequence according to the proportion, start the disperser and stir evenly, and the stirring speed of the disperser is 1100r / min , and the stirring time was 20min to ob...

Abstract

The invention discloses an improved ecological waterborne coating and a preparation method thereof. The ecological waterborne coating comprises water, coconut juice, aloe vera gel, corn whisker, a dispersant, a wetting agent, a defoaming agent, titanium dioxide, calcium hydroxide and a wax emulsion. Compared with the unimproved comparative example 1, the waterborne coating has no lumps and no obvious large particles in a container, has a uniform texture after stirring, exhibits stability without deterioration under low temperature conditions, and has no obstacles after three times of brushingduring construction, a maximum scrubbing-resistant number is up to 850, and far exceeds 300 times of the comparative example 1, probability of coating sagging is small, no obvious sagging signs appear, a formed film is complete at coating appearance, and no obvious cracks exist. Obviously, fine blocks exist after film forming in the comparative example 1, and the formed film is incomplete. After brushing the waterborne coating, the coating can be dried within 1.5 h, and the performance is excellent.

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 environment-friendly ecological 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. [0003] Water-based paints include water-solu...
