Building inner and outer wall decorating plate and manufacturing method thereof

Abstract

The invention discloses a method for building inner and outer wall decorating plate, which comprises two flows, each flow including steps of: a primer line processing flow: (1) thickness sanding and dedusting, (2) roller painting back seal coat and curing into a first UV seal coat layer, (3) roller painting UV penetrant twice, (4) leveling by infrared ray, (5) coating UV putty at the front and UV curing and generating a UV putty layer, (6) roller painting the UV seal coat for three times and respectively curing and generating three second UV seal coat layers, (7) fine sanding; and a roller painting finish line flow: (1) dedusting, (2) roller painting UV glue and generating a first UV glue layer, (3) coating the UV finish for five times and curing and generating five UV finish layers. The decorating plate can solve the problems that a UV curing penetrating agent is strongly, quickly and deeply penetrated into a fiber reinforced calcium silicate slab or a fiber cement slab, deeply cured to form a film and subjected to stereo chemical netlike cross-linking reaction with UV putty and UV sealing paint, and thoroughly solves the problem of adhesive force between the decorative surface layer and a substrate.

Description

technical field [0001] The invention relates to a decorative board and a production method thereof, in particular to a decorative board for interior and exterior walls of a building and a production method thereof. 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, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a decorative panel for interior and exterior walls of a building and a manufacturing method, which can solve the problem of strong penetration, rapid penetration, deep penetration, and deep curing of ultraviolet light-cured penetrants and fiber-reinforced calcium silicate boards or fiber cement boards. Form a film 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 coating on fiber reinforced calcium silicate board or fiber cement board , prone to problems such as poor adhesion between coating layers, poor adhesion between coating layers and boards, poor boiling water resistance and bursting of boards, and efficient industrial production can be realized, thereby greatly reducing the production cost of board making
