Problems solved by technology

However, the existing thermal insulation boards made of thermal insulation materials with a combustion performance above Class A are not ideal in the application of external thermal insulation projects. They generally have poor adhesion to the base layer of the wall, and it is difficult to control the flatness during large-scale construction. The corners of the rear board are easy to protrude, and the anti-cracking mortar has high air permeability and weather resistance requirements, and poor thermal insulation performance, which brings inconvenience to the construction and high cost, which is inconsistent with the concept of energy saving and environmental protection.

The solar heat reflection type heat insulation coating structure has the advantages that the cost is low, the bonding with the wall body is tight, the construction is simple and controllable, the excellent heat reflection cooling and heat insulation effects are realized, the combustion property class requirement is met, and the energy-saving and environment-protection concept is met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a solar heat reflection and thermal insulation coating structure and a preparation method thereof. Background technique [0002] In the existing technology, the thermal insulation of building exterior walls is generally achieved by pasting insulation boards on the surface of the exterior walls. However, the once mature technology of pasting organic insulation boards on the market has been approved by the Ministry of Public Security because the material cannot achieve Class A combustion performance. "Document No. 65" is strictly prohibited to be used on the outer surface of civil buildings. Therefore, the insulation boards currently used are generally made of insulation materials with a combustion performance above Class A. However, the existing thermal insulation boards made of thermal insulation materials with a combustion performance above Class A are not ideal in the applicat...
