Adhesive-type fine-grained-sandstone relief-like decorative material

Abstract

The invention relates to a decorative structure, in particular to an adhesive-type fine-grained-sandstone relief-like decorative material used for building external walls, external walls of vehicles and ships, and the like. The adhesive-type fine-grained-sandstone relief-like decorative material comprises a base wall body, a keel, fixing screws and thermal-insulation decorative boards, wherein thethermal-insulation decorative boards adhere to the base wall body and the other sides of the thermal-insulation decorative boards are fixedly connected to the keel. The adhesive-type fine-grained-sandstone relief-like decorative material is an environment-friendly thermal-insulation decorative composite board with high compression resistance, water impermeability, moisture resistance, air impermeability, light weight, corrosion resistance, long service life, low thermal conductivity and other excellent properties. The adhesive-type fine-grained-sandstone relief-like decorative material permits high permeation, rapid permeation and deep permeation of ultraviolet (UV) curing permeating agents into a fiber-reinforced calcium silicate board or a fiber cement board to achieve deep cure and film forming and to form a three-dimensional chemical reticular cross-linking reaction with UV putty and UV sealers, thereby solving the problem of adhesion of a decorative surface layer to a base board.The invention also provides a flame-retardant material. The flame-retardant decorative board prepared according to a method provided by the invention meets the requirements of national standards in gluing property and imparts a flame-retardant property to a base material. In addition, the mechanical properties of the base material are not affected, and the formaldehyde emission also reaches abovethe E1 level so as to achieve safety and environment protection. Meantime, the natural texture of wood is maintained and the decorative effect is good.

Description

technical field [0001] The invention relates to a decorative plate, in particular to a decorative plate method 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 ...

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
