All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The bi-component micro cement coating provided by the embodiment of the invention consists of a powder material component A and a liquid material component B;
the powder A component comprises the following components in parts by weight: 400 parts of ordinary silica cement, 400 parts of high-alumina cement, 50-100 parts of triple superphosphate, 350 parts of quartz sand, 50-100 parts of quartz powder, 1-3 parts of retarder, 0.5-1 part of fiber, 0.5-1 part of first cellulose, 10-20 parts of dispersible latex powder, 0.6-1 part of first defoaming agent and 0.5-1 part of early strength agent;

Further, the Dispersant (Dispersant) is a surfactant having two opposite properties of lipophilicity and hydrophilicity in a molecule. The amphiphilic agent can uniformly disperse solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquid, and can prevent the particles from settling and coagulating to form stable suspension, and the dispersant in the embodiment can be organic dispersant or inorganic dispersant.
Further, the mildew preventive is an additive for preventing the growth of mildew, the mildew preventive in this embodiment may be a natural mildew preventive, an organic mildew preventive or an inorganic mildew preventive, and the growth of the mildew can be effectively prevented by adding the mildew preventive to the two-component micro-cement coating in this embodiment.
Further, the first cellulose and the second cellulose are both methyl cellulose.
Further, the fibers are glass fibers.
Further, the first defoaming agent and the second defoaming agent are substances capable of reducing the surface tension of water, solution, suspension and the like, preventing foam from forming, or reducing or eliminating original foam, and in the embodiment, the first defoaming agent and the second defoaming agent can be mineral oil-based defoaming agents, silicone defoaming agents or nonionic defoaming agents.
Further, the early strength agent has both an early strength function and a certain water reducing enhancement function, and the early strength agent in this embodiment may be selected from organic compound early strength agents.
Further, the retarder is an additive for reducing the hydration speed and the hydration heat of cement or gypsum and prolonging the setting time, and can be selected from a tartrate retarder or a citrate retarder.
Further, the weight ratio of the powder material component A to the liquid material component B is 2: 1.
It should be noted that the weight ratio of the powder a component to the liquid B component is not limited in this embodiment, and in this embodiment, the weight ratio of the powder a component to the liquid B component is preferably 2: 1.
The raw material of the two-component micro-cement coating in the embodiment is not calcium carbonate which is a common coating in the market, but quartz sand and quartz powder with higher hardness and resistance.
Most of the components of the component A of the two-component micro-cement coating in the embodiment are inorganic mineral materials, are zero-formaldehyde and close to zero VOC, and have higher environmental protection property than common wall and floor decoration materials.
The two-component micro-cement coating can be applied to almost any surface, and can be applied to wall surfaces and ceilings like artistic coatings, such as cement mortar surfaces, terrazzo surfaces, marble surfaces, tile surfaces, gypsum board surfaces, floors with intensive traffic of people and outdoor wall surfaces, and can also be used for decoration of swimming pools and saunas due to its unique water-resistant and acid-resistant properties.
The bi-component micro cement can ensure no cracking. The elastic properties of the FUFINI micro-cement also allow for slight deformation when properly applied.
In the two-component micro-cement coating, since the texture of the ordinary silica cement and the high alumina cement is diversified, the type of the coating layer can be adjusted according to the desired use and location, for example, a smoother type can be used for the interior, and a rougher type can be used for the exterior and wet portions. Because the ordinary silica cement, the high-alumina cement, the quartz sand and the quartz powder have certain roughness, the two-component micro-cement coating in the embodiment has higher anti-skid capability compared with the existing decorative coating on the market.
