Thermal insulation type high-weather-resistance low-carbon 5D granite coating and preparation method thereof

Abstract

The invention discloses a thermal insulation type high-weather-resistance low-carbon 5D granite coating prepared from the following components in parts by weight: 20-30 parts of methyl methacrylate, 10-20 parts of butyl acrylate, 10-20 parts of 2-ethylhexyl acrylate, 1-3 parts of acrylic acid, 2-6 parts of an emulsifier, 1-2 parts of persulfate, 0.3-0.5 part of an oxidizing agent, 0.2-0.3 part ofa reducing agent, 53 parts of water, 10-20 parts of glass beads, 20-30 parts of silicon dioxide, 0.5-1 part of tea polyphenol, 15-20 parts of montmorillonite, 1-3 parts of kaolin deionized water, 1-8parts of a coalescing agent and 5-7 parts of a dispersing agent. Treatment is carried out through a redox system; further residual monomers are reduced, the 5D granite coating has the advantages of low VOC, low odor, environment friendliness and suitability for market popularization; a prepared emulsion adhesive has strong water resistance, acid resistance, alkali resistance and stain resistance,and the added silicon dioxide has good acid and alkali resistance, small silicon dioxide expansion coefficient, high hardness and good acid and alkali weather resistance, and can provide protection for vitrified micro bubbles.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a thermal insulation type 5D granite coating with high weather resistance and low carbon and a preparation method. Background technique [0002] Imitation stone coating is a very popular new product type in the architectural coating industry in recent years. The product is based on the physical and chemical colloid technology and surface treatment technology; a variety of colloidal stone imitation particles of different sizes and colors are evenly and stably suspended Dispersed in water-based emulsion paint, after one construction molding, the pattern effect of the finished imitation granite stone can reach the level of real ones. [0003] Granite paint, as the name suggests, is a stone-like paint whose exterior decoration effect completely resembles natural granite stone. Also called colorful paint. It is mainly made of synthetic resin emulsion as the base mater...

Problems solved by technology

Thermal insulation coatings are typically used on the exterior walls of buildings and large outdoor storage tanks. Commonly used wall insulation technologies at home and abroad are: externally-mounted external thermal insulation polystyrene boards and walls are poured at one time and polystyrene particle thermal insulation mortar for external wall insulation. They all use "heat-resistance" as a means of heat preservation. Although the effect is good, it has a great impact on the load-bearing and exterior decoration of the building itself, and the construction cost also increases. Insufficient, and has no elasticity, can not adapt to the changes of thermal expansion and contraction of the wall or container wall, and is prone to cracking. Therefore, a thermal insulation type, high weather resistance and low carbon 5D granite coating and its preparation method are proposed.
