A kind of preparation method of imitation stone colorful coating

Abstract

The invention relates to a stone-like colorful coating and a manufacturing method thereof. The stone-like colorful coating comprises a bottom plate, a sealing layer, a bottom color layer, a stone-likelayer and a finishing coat that are arranged successively from bottom to top. In addition, according to manufacturing method, the heating and drying processes are reduced by being compared with the existing ones; and thus the efficiency is improved. Since the stone-like colorful dry plate is used for replacing the conventional stone-like-effect coating composition, on the one hand, the heating and drying process of the stone-like-effect coating is removed; and on the other hand, with the stone-like colorful dry plate, the operating place is not easy to pollute and is convenient to clean. Because the stone-like colorful dry plate is able to absorb the moisture of a next bottom color coating, on the one hand, the time for the heating and drying process is shortened and the energy consumption is reduced; and on the other hand, no bulging is caused during the heating and drying operation, so that a technical problem that the bulging is caused easily by the water-based paint during the integrated plate processing in existing production is solved.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation decoration materials for building exterior walls and interior wall decoration materials, and in particular relates to a method for manufacturing a stone-like multi-color coating. Background technique [0002] With the rapid development of the construction industry, people are increasingly advocating artistic effects such as nature, elegance, style, and stability in building decoration. Therefore, natural stone can be used, but the cost of natural stone is high and the construction is inconvenient, so the imitation stone integrated board came into being, which has the luxurious appearance of stone and has a strong three-dimensional effect, but the weight is much less. [0003] For the thermal insulation integrated board for external walls, the usual manufacturing process of the board is: coating the sealing hydrophobic primer formed by the sealing coating composition on the thermal insul...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the existing technology are: 1. when spraying the stone-like effect coating, the paint is in a liquid state with color, and it is easy to pollute the operation site due to splashing and spraying, and it is difficult to clean up; The amount of paint used is large, and the liquid paint itself contains a lot of water. The drying time used is very long, the energy consumption is high, the efficiency is low, the required drying production line is relatively long, and the cost is high; ③Due to the many drying processes, a total of four times , and all require baking until the next step is done. On the one hand, the quality of the construction workers is high, and on the other hand, the whole process has high requirements on the operation. The previous step is slightly improper, and the drying is not dry enough, so the next step Operation, it is easy to cause the coating to bulge during drying, the rate of defective products is high, and the waste is large; ④ Conventional stone-like coatings generally include real stone paint, rock flake real stone paint, and water-in-water colorful

Water-in-water multi-color is prone to unevenness when spraying on the drying line, resulting in different batches of plates and a relatively high defective rate
