Abstract

The invention relates to a heat-insulating true stone paint and a preparation method thereof. The heat-insulating true stone paint comprises, by weight, 15 to 20 parts of pure acrylic emulsion, 70 to75 parts of composite sintered color sand, 3 to 5 parts of auxiliary agents and 8 to 10 parts of water, wherein the auxiliary agents are composed of, by weight, 0.4 to 0.6 part of dodecenoic acid, 0.8 to 1.2 parts of propylene glycol, 0.1 to 0.3 part of neutralizing amine AMP-95, 0.1 to 0.2 part of an antifoaming agent, 0.2 to 0.4 part of cellulose and 0.2 to 0.4 part of an alkali swelling type thickening agent DR-72. The preparation method comprises the following steps: adding water into a stirring tank, then adding dodecenoic acid, propylene glycol, neutralizing amine AMP-95 and cellulose, and carrying out uniform mixing under stirring; then adding the composite sintered color sand and carrying out mixing; then successively adding the pure acrylic emulsion and the antifoaming agent and carrying out mixing under stirring; and then adding the alkali swelling type thickening agent DR-72 and carrying out adjusting to desired viscosity. Compared with the prior art, the invention has the advantages that the preparation method is simple in process, good in controllability and suitable for large-scale industrial production; and the prepared heat-insulating true stone paint has good heat insulation effect and is stable in system, simple in construction conditions, economic and practical.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and relates to a heat-insulating real stone paint and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of architectural decorative coating technology, the use of traditional architectural decorative coatings has become more and more restricted due to technical problems such as high energy consumption, poor safety, and environmental pollution. At present, in the field of construction, it is generally required that multi-storey residential buildings, general industrial buildings and public buildings should have architectural coatings with a service life of more than 5 years, and high-rise buildings should have architectural coatings with a service life of more than 10 years. Among many architectural coatings, real stone paint, as a bright spot of building exterior latex coatings, is the most active and fastest-growing direction of arc...
