Abstract
The invention relates to a composite heat-insulative decorative board which comprises a heat-insulative material layer and a corrosion-resistant material layer. The material layers are bonded and fixed through an organic binding agent, the heat-insulative material layer is prepared from, by weight, 30-50 parts of kaolin, 20-30 parts of acrylic based emulsionpowder, 8-16 parts of hollow silicon dioxide spheres, 5-10 parts of fluoro-phosphazene rubber, 4-8 parts of water repellent, 5-8 parts of fire-proofing agent, 2-5 parts of plantfiber and 3-5 parts of humic acid. The prepared middle heat-insulative layer is very good in sound insulation effect and has good heat-insulation effect by adopting the above components and the proportion. The process is simple, the production cost is low, thefireproofing level is high, and corrosion resistance is good.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a composite thermal insulation decorative board. Background technique [0002] Advocating ecological environment protection is an important concept of sustainable development in modern society. The construction and application of skilled buildings fully demonstrate this point, and also play a positive role in environmental protection, energy conservation and emission reduction. The application of external wall insulation board technology in energy-only buildings has promoted the realization of building insulation projects and the full play of their effects, and is a key requirement for realizing building energy conservation. The external wall insulation board is produced in a factory, and then directly used in the building construction to bond the external wall of the building. It has the functions of heat preservation and waterproof, and it is also an important material for bui...
