Elastic reflective heat insulation paint and preparation method thereof

Abstract

The invention belongs to the technical field of paint application, and in particular, relates to an elastic reflective heat insulation paint and a preparation method thereof. The method comprises the following steps: firstly, stirring evenly cellulose in water, then adding a pH regulator, a dispersant, a wetting agent, a first-added defoaming agent and a bactericide, then adding titanium dioxide, a filler and a reflective powder, carrying out high speed dispersion to grind the powder into proper fineness, then adding a pure elastic acrylic emulsion, a film-forming auxiliary agent, an antifreezing agent, a thickening agent and a second-added defoaming agent, adjusting a paint to an appropriate viscosity, modulating a color, and then packaging and subpacking. The elastic reflective heat insulation paint has the beneficial effects that the elastic emulsion for buildings is used in the formula, is an emulsion synthesized by an ultraviolet crosslinking technology, has excellent stain resistance, and also has excellent weatherability, stability, water resistance and alkali resistance; and the reflective powder has a highly strong near infrared reflection ratio, and can guarantee the colored paint to have relatively high reflectance.

Description

technical field [0001] The invention belongs to the technical field of paint application, and in particular relates to an elastic reflective heat-insulating paint and a preparation method thereof. Background technique [0002] Building thermal insulation coatings are more and more favored by people because of their advantages such as economy, convenience in use and good thermal insulation effect, and their development prospects are broad. At present, according to the different heat insulation mechanisms and methods of coatings, heat insulation coatings can be divided into three categories: barrier heat insulation coatings, reflective heat insulation coatings and radiation heat insulation coatings; [0003] Building energy consumption accounts for one-third of human energy consumption, which is a relatively high proportion. Therefore, improving the thermal insulation performance of buildings is an important way to save energy and improve the use of buildings. It coincides wit...
