Abstract

The present invention proposes a flexible imitation stone veneer sheet and its preparation method, including aggregate, component A and component B, and the aggregate is a mixture of 100-150 mesh natural colored sand and 50-80 mesh natural colored sand ;Component A includes the following raw materials: water-soluble polyvinyl alcohol, potassium persulfate, distilled water, methacrylic acid, styrene, methyl methacrylate, isooctyl acrylate, isooctyl methacrylate, acetoacetoxymethyl Ethyl acrylate, ethylene-vinyl acetate copolymer; component B includes the following raw materials: zinc acetate, ammonia water, water-soluble polyvinyl alcohol and distilled water. On the basis of greatly improving the flexibility of the flexible imitation stone veneer sheet, the invention greatly shortens the time required for preparation, occupies less space for curing, and has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flexible imitation stone veneer sheet and a preparation method thereof. Background technique [0002] Flexible imitation stone, also known as soft stone or soft stone, the main raw materials are inorganic mineral powders such as ore, ore, ore powder, adding a small amount of water-based polymer as a modifier, modified and reorganized through molecular structure, after low-temperature molding Forms a lightweight facing material with some flexibility. Its production cycle is fast, and its appearance has a high degree of stone simulation. It can replace traditional building materials with high energy consumption and low environmental protection such as ceramic tiles, paints, and marble. It is not only safe and has no risk of separation, but also has light weight, aging resistance, and acid and alkali resistance. , freeze-thaw resistance, low construction cost and other...
