Impact-resistant polyurethane surface decoration material

Abstract

The invention discloses an impact-resistant polyurethane surface decoration material. Two major processes are included, firstly, the primer line processing technological process comprises the specificsteps that (1) fixed-thickness sanding and dust removing are conducted, (2) seal coat is roller-painted on the back face and cured into a first UV seal coat layer, (3) a UV penetrant is roller-painted by two times, (4) infrared leveling is conducted, (5) UV putty is painted on the front face, UV is cured to generate a UV putty layer, (6) UV seal coat are roller-painted by three times and cured togenerate three second UV seal coat layers, and (7) fine sanding is conducted; and secondly, the finishing coat line roller-painting technological process comprises the specific steps that (1) dust removing is conducted, (2) UV glue is roller-painted to generate a first UV glue layer, and (3) UV finishing coat is painted by five times and cured to generate five UV finishing coat layers. Accordingto the impact-resistant polyurethane surface decoration material, strong penetration, rapid penetration and deep penetration of the UV curing penetrant and a fiber reinforced calcium silicate plate ora fiber cement plate are achieved, a film is formed through deep curing, the UV curing penetrant, the UV putty and the UV seal coat form a three-dimensional chemical netted crosslinking reaction, andthe problem of adhesive force of a decoration face layer and a base plate can be solved.

Description

technical field [0001] The invention relates to a decorative board and a production method thereof, in particular to an impact-resistant polyurethane surface decoration material. 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 pla...

Problems solved by technology

[0004] The purpose of the present invention is to provide an impact-resistant polyurethane surface decoration material, 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
