Abstract

The invention discloses a finishing paint coating construction process of a high-elasticity UV closed sheet having a matte effect. The finishing paint coating construction process comprises the following steps that the sheet is treated, high-elasticity UV putty is coated in a rolling mode, and the coating amount is 25-30 g / m<2>; a high-elasticity UV primer is coated in a rolling mode, and the coating amount is 60-70 g / m<2>; a high-elasticity UV sanding primer is coated in a rolling mode, and the coating amount is 25-30 g / m<2>; sanding and dust removal treatment is performed; a high-elasticityUV matte surface is coated in a rolling mode, and the coating amount is 25-30 g / m<2>; bending treatment is performed; a protective film is attached, and detection and package are performed. Accordingto the finishing paint coating construction process of the high-elasticity UV closed sheet having the matte effect, the sheet is firstly subjected to coating of the high-elasticity putty, the high-elasticity primer and the sanding primer and then coating of the high-elasticity UV matte surface in the rolling mode, the primer is ground, and then bending is performed, so that an obtained paint filmis uniform and flat in coating, the thickness of the paint film is greatly improved, the problems of crocodile skin and cracking are not likely to occur, and an attachment force is strong.

Description

technical field [0001] The invention relates to the technical field of a chemical coating construction method, in particular to a topcoat coating construction process for a high-elasticity UV-enclosed matte effect thin plate. Background technique [0002] The parapet sheet is a new type of decorative wall material developed in recent years, and generally uses wood as the base material. The protective wall thin board has the characteristics of light weight, fire prevention, moth resistance, and simple construction. It is low in cost, safe in use, obvious in decorative effect, and convenient in maintenance. It can not only replace wooden dado, but also replace wall materials such as wallpaper and wall bricks, so it is widely used. [0003] When decorative wall panels are used, they need to be painted and bent. At present, the main construction process of the bent parapet sheet produced in the market is to directly coat the surface of the bent sheet with veneer without any co...
