Abstract

The invention discloses a method for preparing a pattern-color variable quartz stone plate. Methylpropionic acid type thermoplastic resin: 70~1000 mesh quartz powder: thermochromic pigment component: pigment wetting and dispersing agent: KH570 coupling agent: accelerator: curing agent (mass ratio) = 5~20:50~ 90:0.2~3:0.1~1:0.05~0.5:0.05~0.5:0.05~0.5, methacrylic acid type thermoplastic resin as adhesive, 70~1000 mesh quartz powder as filler, by adding basic discoloration temperature at The temperature-sensitive color-changing pigment components in the range of 0~35°C, the pigments of different colors and different basic color-changing temperatures are reasonably matched, and are mixed and pressed to form patterns and colors under the action of pigment wetting and dispersing agents, coupling agents, accelerators and curing agents A quartz stone plate that changes as the indoor temperature changes. The appearance color of the quartz stone plate prepared by the invention changes with the change of temperature.

Description

technical field [0001] The invention belongs to the technical field of artificial stone preparation, and in particular relates to a method for preparing a variable-color quartz stone plate. Background technique [0002] With the improvement of people's living standards, people's requirements for home decorations are getting higher and higher, and because quartz stone has natural, fresh and beautiful patterns of natural stone, and has good physical properties such as strength and hardness, in recent years, As a new type of environmentally friendly decorative material, it is very popular among consumers in the cabinet market. As a new type of artificial stone, quartz stone is widely used in cabinet countertops, bathroom countertops, dining table countertops, hospital countertops and laboratory countertops. [0003] Quartz stone has the advantages of rich variety, small color difference, high hardness, scratch resistance, high strength, excellent impact resistance, pollution r...
