Compound decorative board of expanded perlite and its preparation method

Abstract

A composite decorative plate is composed of surface layer and base layer. It is prepared through proportionally mixing high-Al cement NO.525, the mixture of quartz sand and powre and the additive containing pigment, stirring, pouring in mould, vibration, absorbing the surfacial water, pouring the mixture of high-Al cement No.525, expanded pearlite and water, and pressure smoothing. Its advantages are high lustre, light weight, fire retarding, and heat and sound insulation.

Description

technical field [0001] The invention relates to an expanded perlite composite decorative board which uses expanded perlite as the main raw material and integrates the advantages of various decorative materials and a production method thereof. Background technique [0002] The decorative materials provided in the market have always had some obvious disadvantages. For example, the disadvantages of natural marble and granite are: heavy, radioactive poisoning, limited color varieties, and the surface gloss of natural marble has been observed.

[0002] The decorative materials provided in the market have always had some obvious disadvantages. For example, the disadvantages of natural marble and granite are: heavy, radioactive poisoning, limited color varieties, and the surface gloss of natural marble has been observed. It will start to lose light and change color after a while, especially the black marble on the exterior surface will eventually turn light yellow over time; the disadvantages of ceramic tiles are: heavy, cold, and hard; the disadvantages of organic materials are: flammable and poisonous , easy to age; the disadvantages of wood are: flammable, not moisture-proof

There are also some products made by the above method. Due to the lack of consideration to solve the problems of high-alumina cement’s late strength drop and the product’s resistance to carbonization, oxidation, and fresh water erosion, the various physical and chemical properties of the product cannot reach the decorative materials. The requirements for use, so far no commercial products of this kind of products have been found on the market
