Embodiment Construction

[0009] Specific embodiments of the present invention will be described in detail below.

[0010] A kind of nano heat insulating paint, comprises following component and the weight ratio of each component is:

[0011]

[0012]

[0013] The beneficial effects of the present invention are: 1) The self-crosslinking elastic acrylic emulsion is selected as the film-forming material, which has high solid content, low film-forming temperature, and surface UV curing, and has excellent elasticity and high viscosity at a wide temperature. 2) The added silica airgel is a nano-scale three-dimensional network skeleton structure formed by the interconnection and aggregation of several Si-O-Si groups. Due to the existence of nearly infinite nanopores, the solid heat transfer can only be transmitted along the pore wall, and the nearly infinite pore wall constitutes a nearly "infinite long path" effect, which makes the thermal conductivity of the solid drop to almost the lowest limit; 3) ...

Abstract

The invention discloses a nanometer heat-insulating coating and belongs to the technical field of coatings. The invention aims to solve the technical problem of poor heat insulating effect of the present heat-insulating coating. The nanometer heat-insulating coating contains the following components in parts by weight: 25-40 parts of deionized water, 35-45 parts of elastic acrylic emulsion, 4-8 parts of silicic acid short aluminum fiber, 5-10 parts of kaolin, 4-8 parts of silicon dioxide aerogel, 20-25 parts of hollow glass beads, 1-3 parts of dispersing agent, 1-3 parts of de-foaming agent and 1-3 parts of stabilizer. The nanometer heat-insulating coating prepared according to the invention has the advantages of construction of film, safety, fireproof property, environment-friendly and energy-saving effects, high cost performance, and the like, and can be widely applied to the heat-insulating coatings of interior and exterior walls of buildings, warehouse, refrigeration storage, and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a nano heat-insulating coating. Background technique [0002] In building energy-saving measures, the thin plastered external insulation system of polystyrene board / extruded plastic board (EPS / XPS) board currently implemented in my country has low fire resistance, easy cracking, water seepage, even hollowing, and falling off, and it will be seriously white in the future. Garbage pollution has buried hidden dangers; polyurethane rigid foam spraying system has poor fireproof performance, and there are potential safety hazards; polystyrene particle insulation slurry and vitrified microbead insulation mortar are fading out due to reasons such as thick coating, long construction period, and poor insulation effect market. The market is badly in need of a thermal insulation coating with fire safety, excellent thermal insulation performance, convenient construction and excellent cost per...
