Aquosity elastic heat preserving insulating paint and its preparing process

Abstract

A water-base and elastic heat insulation coating and the preparation method are provided. The invention adopts the elastic pure emulsion and the silicone-acrylate emulsion as the film former and also adopts the materials such as insulating materials and rutile type titanium pigment talc. The preparation process is that water is added with a dispersant, an antifoamer A, a pH regulator with right amount, propylene glycol and titanium pigment in turns under the stirring speed of 500r / min; the rotary speed is adjusted to 1500r / min and the dispersive degree below 25Mum; then an antifoulant, a mildewproof agent, an antifoamer B, silicone-acrylate emulsion, elastic emulsion and a film forming additive are added to stirred for 10min under the rotary speed of 500r / min and then the rotary speed is adjusted to 300r / min, and two third of the insulating materials are added to stir for 20min; at last, the remaining insulating materials are added to stir for 20min under the rotary speed of 300r / min, and the thickeners A, B are added to stir for 15min; the pH value is adjusted to 7.5 to 9 and a preservative is added to stir for 10min to produce the coating of the invention.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based elastic thermal insulation coating applied on the inner and outer walls of a building and a preparation method thereof. Background technique [0002] The world's industry is increasingly developed, the population is increasing, and human beings are destroying nature, so that the temperature of the earth's surface is also increasing day by day, the earth's resources are becoming increasingly exhausted, and human life and survival are increasingly affected and threatened. Therefore, energy saving and consumption reduction The work has attracted the attention and attention of all countries in the world, and various energy-saving materials have become one of the basic goals of scientific research and technological development in the world. Energy-saving materials will also be more and more popular, especially those closely related to people's lives. construction industry, [0003] Accordin...

Problems solved by technology

In the past, most of the thermal insulation materials implemented on the exterior of buildings in my country were; expanded polystyrene (EPS) board thin plaster external wall insulation system, expanded polystyrene (EPS) particle external wall insulation system and silicate insulation Coatings, etc., but these systems and coatings all have problems such as complex construction, short service life, high maintenance costs, not being environmentally friendly, and the energy-saving effect cannot reach the expected effect. The patent application number is CN200410048047.1. Ceramic beads are used to reduce thermal conductivity to achieve heat insulation effect, but the coating uses xylene, which is harmful to the environment. The patent application number is CN02134827.8 is a water-based heat insulation coating using styrene-acrylic emulsion, which has neither elastic effect nor It cannot provide good weather resistance and aging resistance. The exterior wall paint disclosed in Chinese patent 99106112.8 uses pure acrylic emulsion as the base material, and uses titanium dioxide, light calcium carbonate, etc. as fillers. The aging resistance, heat resistance and insulation properties of such products poor thermal performance
