Problems solved by technology

The existing production process of calcium silicate decorative board is mostly spraying process or roller coating process, but the efficiency of spraying process is low, and the sprayed paint is not easy to recycle and reuse, and the mist generated during spraying is sucked away by the ventilation system, causing raw materials The waste and air pollution make the cost relatively high; and the roller coating process sometimes has very light streaks, and the paint film is not smooth enough

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific examples. The following examples are explanations of the present invention, and the present invention is not limited to the following examples.

[0021] The preparation method of the calcium silicate decorative board provided by the invention comprises the following steps:

[0022] (1) Use 120 sandpaper to smooth the surface of the calcium silicate board with a thickness of 5.5 mm, and fill up the larger holes on the surface of the calcium silicate board with atomic ash;

[0023] (2) Configure sealing waterproofing agent according to the mass ratio of 1825A: 1825B: 1825C=4:1:1, and then roll-coat it on the surface of the above-mentioned calcium silicate board that has been sanded and smooth, and dry it at room temperature for 24 hours before use ;

[0024] (3) Roll-coat UV putty on the surface of the above-mentioned dried calcium silicate board, cure with ultraviolet light, pol...

Abstract

The invention relates to a novel calcium silicate decorative plate production method, and aims to find a production method which can reduce the calcium silicate decorative plate production cost and improve production efficiency and production quality. The production method includes (1), performing thick sanding process on the surface of the calcium silicate; (2),performing roller painting sealing with water-proofing agent; (3), performing roller painting with UV (ultraviolet) putty, curing UV, and polishing and dedusting; (4), performing roller painting with UV undercoat, curing UV and polishing and dedusting; (5), performing shower coating with fluorocarbon undercoat and drying with infrared rays; (6), polishing and dedusting by a sander; and (7), performing shower coating with fluorocarbon finishing coat and drying with infrared rays. The calcium silicate decorative plate is made by shower coating technique, so that efficiency is greatly improved; no streaks are left on the surface of the film, so that the film is smooth, thin, and even and has mirror surface effect, and is free of environmental pollution.

Description

technical field [0001] The invention relates to a calcium silicate decorative board, in particular to a new method for making a calcium silicate decorative board. Background technique [0002] Calcium silicate decorative boards are made of calcium silicate boards, on which waterproof materials such as paints and coatings are laid, and some are also equipped with insulation layers, fireproof layers, and decorative layers. The existing production process of calcium silicate decorative board is mostly spraying process or roller coating process, but the efficiency of spraying process is low, and the sprayed paint is not easy to recycle and reuse, and the mist generated during spraying is sucked away by the ventilation system, causing raw materials The waste and air pollution make the cost relatively high; and the roller coating process sometimes has very light streaks, and the paint film is not smooth enough. Contents of the invention [0003] Aiming at the deficiencies of th...
