Modified inorganic decorative sheet and preparation method thereof

Abstract

The invention discloses a modified inorganic decorative sheet which comprises the following components in parts by weight: 30-50 parts of inorganic powder, 10-40 parts of acrylic emulsion, 50-80 parts of stone sand, 0.001-0.01 part of polyvinyl alcohol fiber, 0.002-0.01 part of cellulose, 0.2-1 part of a water repellent, 0.1-2 parts of pigment, 0.1-0.5 part of a dispersing agent, 0.1-0.5 part of a defoaming agent and 10-20 parts of water. The modified inorganic decorative sheet disclosed by the invention has excellent fireproof performance, can reach A2-grade fireproof grade, also has good elasticity and flexibility, and can be bent by 360 degrees without breakage; by means of the silica gel mold, the vivid decorative effect with rich, diverse and natural textures can be specially achieved according to requirements, and the mold is suitable for decoration of inner and outer walls of villas, schools, hospitals, office buildings, parks, high-rise buildings and the like. The manufacturing process of the product is simplified, the cost is reduced, the efficiency is improved, energy conservation and emission reduction are achieved, noise and dust pollution are avoided, and low carbon and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a modified inorganic decoration sheet and a preparation method thereof. Background technique [0002] Organic decorative panels and glass curtain walls have defects such as waste of resources, serious energy consumption, and complicated processes in their own materials. When applied to building exterior walls, especially high-rise buildings, they have defects such as high cost, complicated construction technology, serious pollution, and easy aging of fixed metal parts. There are many safety hazards in fire and earthquake. [0003] Ceramic tiles and natural stone, due to the limitation of the material of the tile itself, will seriously pollute the environment and consume energy in the process of material production and firing; while the large-scale mining of natural stone will seriously damage the surface resources and cause great harm to the environment . In the pro...

Problems solved by technology

[0002] Organic decorative panels and glass curtain walls have defects such as waste of resources, serious energy consumption, and complicated processes in their own materials. When applied to building exterior walls, especially high-rise buildings, they have defects such as high cost, complicated construction technology, serious pollution, and easy aging of fixed metal parts. There are many safety hazards in fire and earthquake

[0003] Ceramic tiles and natural stone, due to the limitation of the material of the tile itself, will seriously pollute the environment and consume energy in the process of material production and firing; while the large-scale mining of natural stone will seriously damage the surface resources and cause great harm to the environment

In the process of building applications, especially on the exterior walls, in addition to high design requirements, ceramic tiles have defects such as heavy stone, complicated construction technology, difficult renovation, easy aging of accessories, and falling off when natural disasters occur, which will pose a great threat to personal safety. danger and injury, but also generate a large amount of construction waste
