Production process for novel UV decorative plate

Abstract

The invention discloses a production process for a novel UV decorative plate. The production process includes two flows. Specific steps of each of the flows are as follows: I. a process flow of primerline processing: namely a step of (1) flatly sanding by using a sanding machine and removing dust, (2) roller painting back seal coat and solidifying into a first UV seal coat layer, (3) roller painting an UV penetrant twice, (4) performing infrared levelling, (5) front coating UV putty and performing UV curing to form an UV putty layer, (6) roller painting UV seal coat three times and respectively curing to form three layers of second UV seal coat layers, and (7) performing fine sanding; and II. a process flow of roller painting finish paint lines: namely a step of (1) removing the dust, (2)roller painting UV glue to form a first UV glue layer, and (3) painting UV finish coat five times and curing to form five layers of UV finish coat layers. The production process can solve problems that strong penetration, rapid penetration, deep penetration and deep curing into film of UV curing penetrants and fiber-reinforced calcium silicate boards or fiber cement boards, and a three-dimensional chemical network cross-linking reaction with the UV putty and the UV seal coat is formed, and can solve the problem of adhesion of a decorative surface layer and a substrate.

Description

technical field [0001] The invention relates to a decorative board and a production method thereof, specifically a novel UV decorative board production process. Background technique [0002] With the development of society and the continuous improvement of people's living taste, people have also put forward higher requirements for the color and pattern of the interior and exterior walls of buildings, hoping that the patterns and colors of the exterior walls of buildings will be more dazzling and colorful. However, there are the following difficulties in decorating the exterior walls of buildings: 1. The plates used for building exterior wall decoration are mainly fiber-reinforced calcium silicate boards or fiber cement boards, and ordinary coatings on fiber-reinforced calcium silicate boards or fiber cement boards Coatings are prone to poor adhesion between coating layers, poor adhesion between coating layers and plates, poor boiling water resistance of plates, and cracking ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new UV decorative board production process, which can solve the problem of strong penetration, rapid penetration, deep penetration of ultraviolet light curing penetrant and fiber reinforced calcium silicate board or fiber cement board, and deep curing film formation , and form a three-dimensional chemical network cross-linking reaction with UV putty and UV sealing paint, completely solve the problem of adhesion between the decorative surface layer and the substrate, so as to solve the problem of coating on fiber-reinforced calcium silicate board or fiber cement board. Problems such as poor adhesion between coating layers, poor adhesion between coating layers and plates, poor resistance to boiling water and cracking of plates occur, and efficient industrial production can be realized, thereby greatly reducing the production cost of plate making
