Water-based thermal insulation coating and preparation method thereof

Abstract

The invention discloses a water-based thermal insulation coating, which is characterized by mainly comprising the following components in percentage by weight: 13 to 20 percent of rutile type titanium dioxide, 7 to 12 percent of hollow glass bead, 5 to 10 percent of mica powder, 28 to 36 percent of crylic acid emulsion, 0.1 to 0.2 percent of water-based preservative, 0.2 to 0.6 percent of water-based thickener, 0.1 to 0.3 percent of water-based wetting agent, 0.3 to 0.6 percent of water-based dispersant, 0.1 to 0.5 percent of water-based defoaming agent, 0.1 to 0.3 percent of water-based mildew preventive, 0.2 to 0.3 percent of water-based levelling agent, 4 to 8 percent of water-based aluminum paste and the balance of clear water. The water-based thermal insulation coating integrates three functions, namely blocking, reflecting and radiating functions, can reduce or prevent temperature rise caused by intense radiation of sunlight, and can effectively reduce the temperature in a building on the waterproof basis so as to save energy and improve living and working environments.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the technology of water-based heat-insulating coatings. Background technique [0002] There are three types of coatings in the prior art: barrier-type heat-insulating coatings, reflective-type heat-insulating coatings and radiation-type heat-insulating coatings, each of which has its own disadvantages, that is, it cannot provide the functions of barrier, reflection and radiation at the same time. Although waterproof, especially when applied to the surface of a building, it cannot effectively reduce the temperature inside the building. Contents of the invention [0003] The purpose of the present invention is to provide a kind of integrated barrier, reflection and radiation three heat insulation functions as one, which can reduce or prevent the temperature rise caused by strong sunlight radiation, and can effectively reduce the temperature in the building on the basis of waterp...
