Exterior wall heat-preservation decorative plate structure

Abstract

The invention relates to a decorative structure, in particular to an exterior wall heat-preservation decorative plate structure used for exterior walls of buildings, external walls of vehicles and ships, and the like. The exterior wall heat-preservation decorative plate structure comprises a basic layer wall, a keel, a fixing screw and a heat-preservation decorative plate; the heat-preservation decorative plate is attached to the basic layer wall, and the other face of the heat-preservation decorative plate is fixedly connected with the keel. An environment-friendly heat-preservation decorative composite plate has the excellent properties that the compression resistance is high, the non-water-absorbent, moistureproof, airtight, lightweight and corrosion resistant effects are achieved, theservice life is long, and the heat conductivity is low. According to the environment-friendly heat-preservation decorative composite plate, the problems of high penetration, quick penetration and deep-layer penetration of an ultraviolet light curing penetrant and a fiber-reinforced calcium silicate plate or a fiber cement plate can be solved, the environment-friendly heat-preservation decorative composite plate is deeply cured into a film, the environment-friendly heat-preservation decorative composite plate, UV putty and UV sealed paint form a three-dimensional chemical network crosslinking reaction, and the problem of adhesive force of a decorative face layer and a base plate can be solved. The invention further provides a flame-retardant material. The gluing property of the flame-retardant decorative plate prepared through the method can meet the national standard requirement, and a flame-retardant property is given to a basic material; the mechanical property of the basic materialis not affected, the formaldehyde releasing amount is also the E1 level or above, and the safe and environment-friendly effects are achieved; and meanwhile, the natural texture of wood is kept, and the decorative effect is good.

Description

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

AI Technical Summary

Problems solved by technology

However, the cracks in the cement mortar plaster layer and plastering mortar due to construction factors and the curing of the cement base material, and the cracks in the finish caused by the settlement of the joint between the wall and the concrete prefabricated parts directly affect the waterproof and decorative effects of the insulation surface.

In the external wall thermal insulation and decorative panels currently in use, some metal parts can directly transfer air heat to the wall with poor thermal insulation performance, so there is a cold and thermal bridge phenomenon, which greatly reduces the thermal insulation performance of the external wall
