Energy-saving heat-insulating environment-protection coating material for glass and producing method thereof

Abstract

The invention discloses a coat material for glass effective in energy saving, heat insulation and environment protection. The coat material is characterized in that the invention comprises by weight percent of 10 to 65 percent of improved aquosity urethane resin, 0 to 40 percent of modified aquosity acrylic resin, 2 to 55 percent of nanometer metal oxide aquosity paste, 0 to 70 percent of water, and 0 to 5 percent of auxiliary agent. The production method comprises the steps as follows: modified resin is fixed equably with water, the nanometer metal oxide aquosity paste is added, and finally the auxiliary agent is added to mix. The glass coated with the dope has high permeance rate of visible light, while the ultraviolet and the infrared ray (thermal radiation) have extremely low permeance rate, thereby having the function of high efficiency to obstruct the ultraviolet and the infrared ray. Besides, the invention is an environmental protection product taking water as the solvent, and has simple construction method. The coating membrane can solidify into membrane under the room temperature rapidly. The invention is widely used in the energy conservation and heat insulation for door-window glass of all buildings, vehicles and ships.

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...

AI Technical Summary

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
