Two-component back coating material for rock plate and preparation method of two-component back coating material

Abstract

The invention relates to the technical field of rock plate back coating material processing, and particularly discloses a two-component back coating material for a rock plate and a preparation method thereof, and the two-component back coating material is prepared from a powder mixture and a liquid mixture; the powder mixture is mainly prepared from the following raw materials: quartz sand, ordinary Portland cement, cement-based capillary crystalline master batch, hydroxyethyl cellulose, dispersible latex powder, diatomite, bamboo charcoal powder and aluminum oxide; the liquid mixture is mainly prepared from the following raw materials: a water-based polymer emulsion, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, sodium citrate, a penetrating agent, a wetting agent and a silane coupling agent. According to the two-component back coating material, the synergistic effect of the raw materials is utilized, so that the two-component back coating material has relatively high bonding strength, thermal aging resistance and freeze-thaw resistance, shows good bonding stability and sound absorption and noise reduction effects, meets the market requirements and expands the application range.

Description

technical field [0001] The present application relates to the technical field of slate back-coating material processing, and more specifically, it relates to a two-component back-coating material for slate and a preparation method thereof. Background technique [0002] With the development of the construction industry, people's requirements for architectural decoration are also increasing. Slate is processed from natural mineral rock and kaolin. It has the advantages of good impact resistance, excellent wear resistance, beautiful appearance and easy cleaning, and is loved by consumers. The paving of rock slabs is inseparable from the back coating material, which is generally made of quartz sand, cement, and water after mixing. It mainly relies on the mechanical bite force of the back coating material to pave the rock slabs. In practical application, the inventors found that although the back-coating material can realize the bonding of rock slabs, the bonding strength is rel...
