Manufacturing method of outer wall heat-preservation decorating plate with vacuum heat-insulation function

Abstract

The invention discloses a manufacturing method of an outer wall heat-preservation decorating plate with a vacuum heat-insulation function and further provides a flame-retardant material. The manufacturing method comprises two procedures, namely the primer line processing technical procedure and the finishing coat line roller-coating technical procedure. The primer line processing technical procedure comprises the specific steps that 1, constant-thickness sanding and dust removing are conducted; 2, roller-coating of back surface seal coat is conducted, and the back surface seal coat is cured into a first UV seal coat layer; 3, roller-coating of ultraviolet (UV) penetrating agents is conducted for two times; 4, infrared leveling is conducted; 5, the front surface is coated with UV putty, andUV curing is conducted to generate a UV putty layer; 6, roller-coating of the UV seal coat is conducted for three times, and the UV seal coat is cured to generate three second UV seal coat layers; and 7, fine sanding is conducted. The finishing coat line roller-coating technical procedure comprises the specific steps that 1, dust removing is conducted; 2, roller-coating of UV glue is conducted togenerate a first UV glue layer; and 3, UV finishing coat is smeared for five times and cured to generate five UV finishing coat layers. According to the manufacturing method of the outer wall heat-preservation decorating plate with the vacuum heat-insulation function, strong, rapid and deep permeation of UV curing penetrating agents and a fiber-reinforced calcium silicate plate or a fiber cementplate can be achieved, deep curing film-forming is achieved, the UV curing penetrating agents, the UV putty and the UV seal coat form a stereo chemical net-shaped cross-linking reaction, and the adhesive force problem of a decorating face layer and a base plate can be solved. The gluing property of the flame-retardant decorating plate prepared through the manufacturing method meets the national standard requirement, and a base material has the flame-retardant property; the mechanical property of the base material is not affected, the formaldehyde emission is also in the grade E1 or above, andthus safety and environmental protection are achieved; and meanwhile, the natural texture of wood is kept, and the decorating effect is good.

Description

technical field [0001] The invention relates to a decorative board and a production method thereof, in particular to an exterior wall thermal insulation decorative board with vacuum heat insulation 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 lay...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for making an exterior wall thermal insulation decorative board with vacuum heat insulation, which can solve the problem of strong penetration, rapid penetration, Deep penetration, deep curing to 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 problem of fiber reinforced calcium silicate board or fiber cement Coating paint on the board is prone to problems such as poor adhesion between paint layers, poor adhesion between the paint layer and the board, poor resistance to boiling water and cracking of the board, and efficient industrial production can be realized, thereby greatly reducing the cost of board making Cost of production
