A kind of inorganic reflective heat insulation lotus leaf coating and preparation method thereof

Abstract

The invention discloses inorganic reflective-insulation lotus leaf paint which is mainly prepared from the following raw materials: an inosilicate film forming matter, a composite reflective insulation material, rutile titanium dioxide, waterborne acrylic emulsion, an organosilicone adjuvant, a silane coupling agent, glycol, a dispersing agent, a wetting agent, a defoaming agent, a thickening agent, a buffering agent, a viscosity stabilizer and water, wherein the composite reflective insulation material is prepared from the following raw materials: thermal reflective insulation powder, kieselguhr, a compound aluminium silicate functional pigment, aedelforsite and mica powder. The inorganic reflective-insulation lotus leaf paint not only has an excellent thermal reflective insulation effect on building base materials, but also is capable of reducing indoor temperature to 20-25 DEG C in summer by virtue of optimization on the composite reflective insulation material; the reflective insulation compound material contains no organic waste gases such as formaldehyde and no APEO, is health-care and environmental-friendly, achieves a lotus leaf effect and is antifouling. The invention also discloses a preparation method of the inorganic reflective-insulation lotus leaf paint.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation coatings, and in particular relates to an inorganic reflective thermal insulation lotus leaf coating and a preparation method thereof. Background technique [0002] In buildings, the heat loss of the outer envelope structure is relatively large, and the wall accounts for a large share in the outer envelope structure. Therefore, the reform of building walls and the development of wall energy-saving technology are the most important links in building energy-saving technology, and the development of external wall insulation technology and energy-saving materials is the main way to realize building energy conservation. [0003] Exterior wall insulation technology originated in Europe, and our country began to pilot it in the mid-1980s, and widely used this technology in the construction field. However, the current level of building energy efficiency is still far lower than that of develope...

Problems solved by technology

[0007] In the prior art, there are also many patents or documents disclosing thin-layer inorganic reflective heat-insulating coatings, which use inorganic potassium silicate, hollow glass microspheres, metal oxides, etc. to prepare reflective heat-insulating coatings. There is a lack of stain resistance; and the addition of hollow glass microspheres is small, and the effect of reflective heat insulation in practical applications is limited
