Burnt stone-like sand-in-water environment-friendly paint with high stability and preparation method thereof

Abstract

The invention discloses a burnt stone-like sand-in-water environment-friendly paint with high stability and a preparation method thereof. The paint is composed of a base paint, protective glue, a continuous phase and a mortar material, wherein a weight ratio of the base paint to the protective glue to the continuous phase is 1-2: 0.35-0.75: 0.5-0.75, and a weight ratio of the mortar material to the gross weight of the base paint, the protective glue and the continuous phase is 1: 1. In the paint, the mortar material and the continuous phase both have sandy texture, so the spraying effect of the paint has stone permeability and a high simulation degree, lichee-surface effect of a burnt stone-like material can be obtained through direct spraying without priming of an intermediate base, one-shot forming is realized, and construction and material cost is saved; since an emulsion is prepared by using a special silane grafting process and a soap-free system, an obtained film has good sealing performance as regard to a substrate and excellent weatherability and stability; as the pain contains a special silane group, colored masterbatch in the sand-in-water paint has certain strength and toughness, so wearing of the colored masterbatch is prevented; and since the emulsion does not contain APEO, the paint meets requirements on greenness and environmental protection.

Description

technical field [0001] The invention relates to the field of preparation of architectural coatings, in particular to an environmentally friendly sand-in-water coating with excellent stability and a high degree of imitation of fired slab stone and a preparation method thereof. Background technique [0002] The development and progress of society has made modern people's awareness of the surrounding environment constantly improved. The concept of caring for the earth, protecting our health, and returning to nature is more and more advocated and pursued by modern people. Therefore, the harmonious coexistence of nature and human settlements makes people drive towards safety and environmental protection to the selection of building materials imitation marble paint. The excellent performance of water-based multi-color paint and the high imitation of stone endow it with a wide range of applications. Water-based multi-color paint is favored by customers for its unique effects. [0...

Problems solved by technology

The burning stone processing technology has certain shortcomings and limitations: first, the rough burning surface can only be used for granite stone; second, after the stone is burned at high temperature, the surface cracks, the weathering resistance decreases, and some white flowers Rust and freckles are highlighted on the rough surface of the granite after burning; third, the
