Problems solved by technology

[0003] (1) Solvent-based or oil-based glass heat-insulating coatings, although the dispersion liquid has good stability, the content of volatile organic solvents exceeds the standard, which causes great environmental pollution;
[0004] (2) Water-based heat-insulating coatings dispersed through high-power consumption grinding, although environmentally friendly, have disadvantages such as large production energy consumption, poor heat insulation and stability;
[0005] (3) Some use water-based environmentally friendly resins, but the coating film has poor water and scrub resistance, or poor film-forming performance, and needs to be baked and cured at a higher temperature, which increases the difficulty of construction and maintenance;
[0006] (4) Binary nano-metal oxides are mostly used in domestic thermal insulation coatings, which have narrow thermal insulation bands and unsatisfactory UV shielding performance, and some prices are high

Embodiment Construction

[0027] The formulations of energy-saving, heat-insulating and environment-friendly coating materials for glass in Examples 1-5 are shown in Table 1. Among them, the nano-metal oxide aqueous slurry is combined into a nano-water dispersion by stirring and dispersing the nano-coating film material in the patent "ZL00129358.3" and water at a temperature of 100-400°C and a pressure of 0.1-40MPa In order to have a better dispersion effect, the nano-coating material in the present invention can also be prepared without adding coupling agent and surface coating agent when making (that is, in the final process of the original patent "ZL00129358.3" preparation method), brackets The inner value is the solid content of the nano metal oxide aqueous slurry, and the particle size is 40-200nm. The described modified water-based polyurethane resin, modified water-based acrylic resin, and auxiliary agents (such as leveling agent, wetting agent, defoamer, etc.) can directly adopt commercially av...

Abstract

The invention discloses an energy-saving, heat-insulating and environment-friendly coating material for glass, which is characterized in that it contains 10-65% of modified water-based polyurethane resin, 0-40% of modified water-based acrylic resin, and 2-55% of modified water-based acrylic resin. The nanometer metal oxide water-based slurry, and 0-70% water and 0-5% additives, the production method: mix the modified resin and water evenly, then add the nanometer metal oxide water-based slurry to mix and stir, and finally Add additives and stir evenly. The glass coated with this coating has high transmittance of visible light, but extremely low transmittance of ultraviolet and infrared (heat radiation), and has the function of effectively blocking ultraviolet and infrared. The invention is a green and environment-friendly product using water as a solvent. The construction method is simple, and the coating film can be quickly cured to form a film at room temperature. It is widely used in energy-saving and heat insulation of various buildings, vehicles, ships and other door and window glass.

Description

technical field [0001] The invention relates to an energy-saving, heat-insulating and environmentally-friendly coating material for glass and a production method thereof. It is a functional and environmentally-friendly coating compounded by a multi-component inorganic nano-particle aqueous dispersion and a modified water-based polyurethane resin, and belongs to various types of glass ( The technical field of forming a transparent energy-saving and heat-insulating coating film on the surface of organic glass is included. Background technique [0002] Due to global warming and greenhouse gas emissions are becoming more and more serious, energy saving and consumption reduction, CO reduction 2 Gas emissions have become the common goal of all countries in the world. my country's Eleventh Five-Year Plan has established the goal of reducing national energy consumption by about 20%. The Ministry of Construction has promulgated building energy conservation regulations, and energy con...
