Chromatic composite rock slices and method for preparing same

Abstract

The invention relates to a colorful composite rock sheet and a preparation process thereof. The composite rock sheet is prepared by raw materials based on weight part: 60-65 parts of water-base resin, 5-8 parts of film-forming auxiliary agent and 30-35 parts of natural ore powder. The process comprises the following steps: (1) adding raw materials in a burden charging barrel according to a formulation, stirring, dispersing, evenly mixing and conducting a filter treatment; (2) spraying into a sheet shape by using a sprayer, and conducting the first drying treatment with a temperature between 50 DEG C and 120 DEG C; (3) immersing the sheet-shaped material which is sprayed and dried into a solvent for at least five minutes, then conducting the second drying treatment with the temperature between 50 DEG C and 120 DEG C; (4) crushing into fragments with irregular size by a grinder, and obtaining finished products after screening. The beneficial effect of the invention is that the sheet is conducted with twice drying treatments and the immersion treatment. The rock sheet has the characteristics of easy color matching, softness, non bonding and color fading, difficult solution and easily even dispersion when making up granite paint.

Description

technical field [0001] The invention relates to the field of chemical building materials, and mainly relates to a colored composite rock slice and a preparation method thereof. Background technique [0002] The colored composite rock flakes currently on the market are "wet rock flakes" soaked in synthetic resin emulsions, which are mainly composed of synthetic resin emulsions, film-forming aids, thickeners, propylene glycol, defoamers, dispersants, and natural colored minerals. After the powder is mixed and prepared, it is dried and broken into shapes. In order to prevent the rock slices from sticking, they must be soaked in synthetic resin emulsion. [0003] Because the rock chip product is too large, the color is not easy to match. After preparing the rock paint, if it is stored for too long, it will be easily dissolved and faded, and the spray gun will be easily blocked during construction. Contents of the invention [0004] The present invention aims to solve the abo...
