Problems solved by technology

[0003] So far, most of the reflective and heat-insulating coatings launched on the market are white or light-colored, but white or light-colored coatings have poor stain resistance, and the reflection efficiency decreases significantly after a period of use; a single white will cause certain Light pollution and poor decoration, in the use of exterior walls, the use of white paint does not exceed 20%, most of which are mainly dark colors

Abstract

The invention discloses a dark-color reflective and heat insulation varnish and a preparation method thereof, relating to the field of coatings. The dark-color reflective and heat insulation varnish comprises the following components in parts by weight: 320-380 parts of an elastic emulsion, 40-80 parts of a fluorocarbon emulsion, 220-270 parts of filler, 4-6 parts of a dispersing agent, 3-5 parts of a defoaming agent, 5-10 parts of a film-forming additive, 3-5 parts of a flatting agent, 5-8 parts of a thickening agent, 2 parts of a mildew-proof and alga-proof agent, 2 parts of a bactericide, 3-5 parts of a wetting agent and 200-250 parts of deionized water. The varnish belongs to an environment-friendly coating, not only is high in reflection coefficient and radiation coefficient, free of grinding and good in decoration property, but also does not contain APEO and cannot generate hazards to the environment and human health.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a dark reflective thermal insulation paint and a preparation method thereof. Background technique [0002] At present, in order to improve the indoor temperature in hot summer and cold winter regions and hot summer and warm winter regions, the energy consumption of air conditioners has become the main aspect of building energy consumption, and it shows a trend of increasing year by year. Therefore, it is imminent to reduce building energy consumption and improve energy utilization. As a new type of building material, reflective heat insulation coating can effectively reduce the temperature of the coated surface and reduce the transfer of heat to the house. It is widely used in construction, transportation, and petrochemical fields. [0003] So far, most of the reflective and heat-insulating coatings launched on the market are white or light-colored, but white or light-colored...
