Outer wall heat-preservation decorative board structure

Abstract

The invention relates to a decorative structure, in particular to an outer wall heat-preservation decorative board structure used for outer walls of buildings, outer walls of cars and ships and the like. The outer wall heat-preservation decorative board structure comprises a base wall body, keels, fixing screws and heat-preservation decorative boards, the heat-preservation decorative boards are bonded to the base wall body, and the keels are fixedly connected to the other faces of the heat-preservation decorative boards; the outer wall heat-preservation decorative board structure is an environment-friendly heat-preservation composite board which has excellent performance such as great pressure resistance, a good water insulation effect, good moisture resistance, high air impermeability, light weight, excellent corrosion resistance, a long service life and low heat conductivity coefficients. The outer wall heat-preservation decorative board structure can solve the problems of high permeability, rapid permeability and deep permeability of ultraviolet-curable permeating agents and fiber-reinforced calcium silicate boards or fiber cement boards, is deeply solidified into membranes, undergoes a stereoscopic chemical network cross-linking reaction with UV putty and UV sealing paint and can solve the problem of an adhesion force of decorative surface layer and base plates. A flame-retardant material is also provided. The gluing performance of a flame-retardant decorative board prepared by a method meets the requirements of national standards, and a substrate has flame-retardant performance; furthermore, the mechanical performance of the substrate is not influenced, the emission amount of formaldehyde is also above the E1 level, and safety and environmental protection are achieved. At the same time, the natural texture of wood materials is maintained, 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
