Description

Technical Field

[0001] The present invention relates to building materials, and more particularly to a coating and a production process thereof. Background Art

[0002] Paint, traditionally known as paint, is a viscous liquid that is applied to the surface of an object to be protected or decorated and can form a continuous film that is firmly attached to the object. It is usually based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water.

[0003] The invention patent with announcement number CN104761989B discloses a composite inorganic metal velvet paint and its production process, which is prepared by the following raw materials calculated by mass percentage: water 5-30%, inorganic silicon binder 10-20%, cellulose 0.2-0.4%, wetting agent 0.2-0.4%, leveling agent 0.3-0.5%, antifreeze agent 0.2-0.8%, organic silicon defoamer 0.2-0.4%, fluff powder 5-15%, pearl powder 10-20%, sericite powder 5-10%, glass sand 25-30%, photocatalyst powder 0.1-0.4%, suspension thickener 5-10%, emulsion 10-20%, anti-settling agent 1.7-3.3%, preservative 2-4.4%, silver ion mildew inhibitor 0-0. 2%, colorant 0-2%. The paint uses fiber fluff powder as the main raw material, and sericite powder and metal pearl powder as fillers. Therefore, it has a luxurious pearlescent appearance, high brightness, and good decorative effect, but its anti-ultraviolet function is weak, so its aging resistance is poor and it is easy to fade. In addition, in the production process of the paint, in order to ensure the uniform mixing of the raw materials, in each step of its preparation method, there is an operation of stirring to make them dispersed evenly. Therefore, the raw materials need to be transported frequently. When the raw materials are processed on the same floor of the factory, transportation is more convenient. However, in the actual production process, in order to save space, different processing processes are not on the same floor. They are generally arranged in sequence from low floors to high floors. Therefore, manual transportation from low to high is required, which makes the operation more troublesome, time-consuming and labor-intensive. Summary of the invention
