Abstract

The present invention relates to a protective coloring material used for concrete surfaces. The coloring material is composed of component A and component B, wherein the mass ratio of the component A and the component B is 1:2 to 1:4. The component A is composed of the following ingredients, by mass: 10-20 parts of water, 0.1-0.3 parts of cellulose, 4-8 parts of elastic latex, 5-10 parts of flexible latex, 0.3-0.7 parts of polyvinyl alcohol, 0.1-0.3 parts of anti-crack fiber 1, 0.3-0.8 parts of anti-crack fiber 2, 0.1-0.5 parts of a dispersant, and 0.1-0.2 parts of a preservative; and the component B is composed of the following ingredients, by mass:13-25cement parts of cement, 10-15 parts of coal ash, 20-25 parts of heavy calcium carbonate powder, 15-30 parts of sand, and0-0.2 parts of iron oxide black powder. The protective coloring material used for concrete surfaces of the present invention can has the effect of fair-faced concrete, and has super strong adhesion performance and weather resistance, so the protective coloring material can provided lasting protection to the concrete.

Description

technical field [0001] The invention relates to a protective coloring material, in particular to a protective coloring material which can be used on concrete surfaces and a preparation method thereof. Background technique [0002] As people pursue the diversification of decorative effects, the pure primary color effect of fair-faced concrete is more and more popular among people. The consistency of concrete color can be ensured only within a short construction period, and the promotion of fair-faced concrete in China has encountered certain resistance. Therefore, people are batch-coating thick paints with the effect of fair-faced concrete on the cast-in-place concrete to meet the needs of the construction period and decorative effects. At present, most of the anti-faced concrete paints are divided into several processes, primers and intermediate coats with different functions. , Topcoat composition. A protective coloring material for concrete surface provided by the invent...
