Problems solved by technology

The inorganic dyeing method needs to burn the dyed material and the sand source together at high temperature, which consumes a lot of energy, but has good mechanical stability; the organic dyeing method is to blend the color paste and film-forming material with the sand source and then dry at room temperature or bake at low temperature Formed, low energy consumption but poor mechanical stability
Moreover, the organic sand dyeing method is also accompanied by VOC emissions, which is not conducive to environmental protection.

Abstract

The invention discloses a pulp for artificial sand dyeing and a preparing method thereof. The pulp is prepared from water-soluble acrylic amino adhesive and sand sources; a base material of the water-soluble acrylic acid amino adhesive is prepared from water-soluble acrylic resin, water, a dispersing agent, an anti-settling agent, a flatting agent, an antifoaming agent, a thickening agent, rutile titanium dioxide, calcined kaolin and amino resin. According to the pulp, the water-soluble acrylic resin and the amino resin are subjected to a curing crosslinking reaction under the condition of low-temperature roasting, and are matched with all the assistants, and the water-soluble acrylic acid amino adhesive is prepared. The sand sources are dyed with the water-soluble acrylic acid amino adhesive, prepared artificial color sand has the high mechanical stability, and compared with the mechanical stability of conventional artificial color sand, the mechanical stability of the prepared artificial color sand is prolonged to be 2 h, and the color is invariable; as the water-soluble resin is adopted, VOC discharging is low, and the pulp is ecological and environmentally friendly.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an artificial dyed sand slurry mainly used for real stone paint and a preparation method thereof. Background technique [0002] In recent years, with the development of the real estate industry, the application of architectural coatings has become more and more extensive, and the dosage is also increasing. Among them, real stone paint has the effect of imitating natural stone, marble and granite, and occupies an irreplaceable position in architectural coatings. One of the main raw materials of real stone paint is natural colored sand, which needs to be mined in some ore sources, and then crushed and screened. The mining of mines not only severely damages the local original ecological environment, but also produces dust particles that are one of the main pollution sources of smog. On the other hand, natural colored sand has the characteristics of poor batch stability, which...
