Abstract

The invention relates to a colorful composite rock sheet and a preparation process thereof. The composite rock sheet is prepared by raw materials with following proportion by weight, 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 that firstly adding raw material in a burden charging barrel according to formulation, and conducting filter treatment after evenly mixing through stirring and dispersing, secondly conducting one-stage drying treatment after spraying into sheet shape with a spraying machine, wherein temperature is controlled within 50 DEG C-120 DEG C, thirdly immersing sheet-shaped material which is sprayed and dried into solvent for at least five minutes, then conducting with two-stage drying treatment, wherein temperature is controlled within 50 DEG C-120 DEG C, fourthly disintegrating into fragments with irregular size with a disintegrator, and obtaining finished products after screening. The beneficial effect of the invention is that the sheet is conducted with two times drying treatments and 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 color composite rock chip and a preparation method. Background technique [0002] The color composite rock chips currently sold on the market are "wet rock chips" soaked in synthetic resin emulsion, which are mainly composed of synthetic resin emulsion, film-forming additives, thickeners, propylene glycol, defoamers, dispersants, and natural colored minerals. After the powder is mixed and formulated, it is dried and broken into a shape. In order to prevent the rock flakes from sticking, it must be soaked in a synthetic resin emulsion. [0003] Due to the large size of the rock slice, the color is not easy to match. After the rock paint is prepared, it is easy to be dissolved and faded when stored for too long, and it is easy to block the spray gun during construction. Summary of the invention [0004] The present invention aims to solve the above-mentioned defects of...
