This patent has richened the apparent effect of traditional terrace material for the terrace shows marble effect, but the antiskid effect of the terrace that obtains at last is not enough.

CN102660168A discloses a preparation method of an artificial granite coating and the artificial granite coating, which comprises the following steps: (1) preparing a base paint; (2) toning, namely adding pigment into the base paint; (3) granulating to form a water-insoluble coating film on the surface of the base paint particles, and dispersing the coating film in a water-based system in a particle state; (4) coating to obtain the granite-like coating; the coating that this patent obtained at last can reach a great deal of decorative effect that granite has, has avoided the defect of natural stone material in decorating, but the terrace that obtains at last does not have anti-skidding effect.

Therefore, the anti-skidding floor paint with the effect of rough granite stone needs to be developed, which can effectively make up for the defects, is environment-friendly and energy-saving, and has high practical value.

Disclosure of Invention

The invention aims to provide a sand-in-sand base paint, a preparation method thereof, a sand-in-sand multicolor paint containing the same and a floor coating. The rough granite-like floor coating provided by the invention has an excellent anti-skidding effect, has the characteristics of weather resistance, acid resistance and alkali resistance, and overcomes the defects of single color and single effect of the floor coating.

In order to achieve the purpose, the invention adopts the following technical scheme:

in a first aspect, the invention provides a sand-in-sand base paint which comprises the following components in parts by weight:

the sand-coated sand base paint provided by the invention has the advantages of environmental protection, high hardness, random color matching and the like, and when the sand-coated sand base paint is applied to floor paint, the paint surface is uneven and has higher roughness, and a good matte effect is achieved.

If the addition amount of the quartz sand is not in the limited range of the invention, the less the sand addition amount is, the smaller the roughness (the degree of unevenness) is, the better the rough surface effect can not be achieved, and the anti-skid effect is also poorer; when the sand adding amount exceeds the range, the color point coating property is poor, sand falling is easy to occur during granulation, the color point specific gravity is high, the storage stability and the like of the sand-coated sand multicolor paint are negatively affected, water diversion is easy to occur, and meanwhile, the performance of the coating is reduced along with the increase of the sand adding amount; the limited range of the invention is the optimal proportioning.

Performance test 1

The sand-in-sand multicolor paints provided in preparation examples 1 to 7 and comparative preparation examples 1 to 13 were tested by the following methods:

(1) color point stability: standing the sand-coated sand multi-color paint for 2 weeks, and observing whether color points are stable or not;

(2) storage stability: standing for 2 weeks, and observing whether water is separated from the appearance and whether the viscosity is obviously changed greatly;

(3) the effect of the rough surface is as follows: whether obvious concave-convex effect exists or not is determined visually, the concave-convex effect is 'A', and the non-concave effect is 'B';

(4) coating performance: spraying the sand-coated sand multicolor paint with the area of 10 multiplied by 10cm, observing whether the sand-coated sand multicolor paint forms a film or not, and taking the following judgment standards as follows:

stage I: forming a film, and the film is not torn when the film is lifted and naturally hangs down;

II stage: forming a film, and slightly tearing when the film is lifted and naturally hung down;

II stage: the film is formed apparently, and is not broken, but cannot be lifted;

stage IV: no film is formed;

the test results are shown in table 1:

TABLE 1

According to the preparation examples and performance tests, the sand-coated sand multicolor paint obtained by the invention has good stability and excellent storage stability. As is clear from the comparison between preparation example 1 and preparation examples 4 to 5, when the particle size of the quartz sand is too small or too large, the film forming property or the concavo-convex effect of the particle size may be affected; as is clear from comparison of preparation example 1 with comparative preparation examples 1 to 12, the effects can be optimized only if the amounts of the respective components are within the range defined in the present invention.

Performance testing

The anti-slip effect test was performed on the terraces provided in examples 1 to 7 and comparative examples 1 to 13, and the roughness was expressed as follows:

(1) roughness: and calculating the difference value of the concave points and the convex points of the floor paint plane to obtain an average value, and recording the average value as roughness.
