Sandstone veneer stone and manufacturing method thereof

Abstract

The invention discloses a sandstone veneer stone. The sandstone veneer stone comprises a base material, an elastic coating arranged on the base material in a coating mode, a colored middle layer arranged on the elastic coating in a coating and rolled mode, an effect layer formed by spraying the sandstone on the colored middle layer, and a protection layer arranged on the effect layer in a coating mode. The protection layer is nanometer fluorocarbon paint. The sandstone paint comprises 30% sandstone paste and 70% natural color sand. The sandstone paste comprises, by weight, 25%-30% of deionized water, 0.2% of multifunctional assistant, 0.25% of defoamer, 70% of synthesis E505, 22%-35% of 800-mesh coarse whiting, 30% of silicon elastic emulsion, 2% of propylene glycol, 2%-3% of coalescing agent and 3.5% of inorganic gel. The sandstone veneer has the advantages of being convenient to transport and construct, stable in variety, smooth in hand feeling and delicate.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, it relates to sandstone veneer stones and a manufacturing method thereof. Background technique [0002] At present, when building walls are decorated with sandstone, either natural sandstone is directly pasted on the surface of the building wall, or colorful paint is sprayed on the composite coil, and then the composite coil is pasted on the surface of the building. [0003] When using natural stone for decoration, because the natural stone is heavy, it is very difficult to transport and construct, and the mining of natural stone is not conducive to the protection of ecology and the environment; The pattern is not stable, the hand feel is poor, and because the paint is exposed to the external environment, it is easy to cause the paint to fade after being exposed to rain and sun, and the color duration is too short. Contents of the invention [0004] In view of the deficienc...
