Preparation method of lightweight sound-insulation wall-decoration artificial stone slab

Abstract

The invention discloses a preparation method of a lightweight sound-insulation wall-decoration artificial stone slab. The mass ratio of methacrylic acid prepolymer resin to 325-mesh glass beads to 400-mesh glass powder to short-cut glass fiber with the length of 0.3 millimeter to color paste: a wetting dispersant to an antifoaming agent to a promoter to a curing agent is 25-60: 10-30: 15-35: 0.5-3: 0.05-2: 0.05-0.5: 0.001-0.01: 0.25-1: 0.25-1. The preparation method comprises the following steps: pouring the methacrylic acid prepolymer resin into an agitator and stirring; adding the color paste, the wetting dispersant, the antifoaming agent and the curing agent during the stirring process so as to prepare mixed resin; mixing the 325-mesh glass beads, the 400-mesh glass powder and the short-cut glass fiber with the length of 0.3 millimeter, and pouring the mixture into the mixed resin; adding the promoter during uniform stirring process; stirring continuously to prepare a mixed slurry after stirring; and introducing the mixed slurry into a plate-making mould for vacuum solidification, demoulding, and conducting dry brushing and water grinding so as to prepare the lightweight sound-insulation wall-decoration artificial stone slab. The method provided by the invention has advantages of simple process, low equipment requirement and low cost, and is easy for large-scale popularization. In addition, the prepared artificial stone slab has excellent comprehensive properties.

Description

technical field [0001] The invention belongs to the technical field of artificial stone preparation, in particular to a preparation method of a light-weight sound-insulating wall decoration artificial stone plate. Background technique [0002] In China's rapidly developing home furnishing industry, people's pursuit of quality of life is getting higher and higher. Artificial stone products are more and more used in architectural decoration on floors, countertops, and walls. Artificial stone is colorful, non-radioactive, and easy to use. It has many advantages such as renovation, crack resistance, good plasticity and good processing performance, and is accepted by more and more architects and designers. [0003] However, among the current artificial stone varieties, there are few varieties used for walls, and there are still disadvantages such as bulkiness, poor sound insulation effect, and cannot be used outdoors, which not only increases the pressure on construction, but als...
