Energy-saving glass for doors and windows

Abstract

The invention provides energy-saving glass for doors and windows, which comprises a glass substrate and an energy-saving coating coated on the surface of the glass substrate, wherein the glass substrate comprises the following raw materials in parts by weight: 80-90 parts of waste glass, 3-9 parts of ground calcium carbonate, 1-2 parts of coarse borax, 1-2 parts of zinc white, 1-2 parts of boron oxide, 10-15 parts of sodium oxide, 1-5 parts of ferric oxide, 10-20 parts of magnesium oxide, 10-20 parts of aluminum oxide, 10-15 parts of calcium oxide, 30-50 parts of silicon oxide, 1-2 parts of magnesium oxide, and 50-70 parts of water. The energy-saving coating comprises the following raw materials in parts by weight: 30-70 parts of resin, 25-80 parts of powder filler, 10-55 parts of hollow ball filler, and the like. The energy-saving glass provided by the invention has good sound-absorbing, noise-reducing and heat-insulating functions, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an energy-saving glass for doors and windows. Background technique [0002] Due to global warming and greenhouse gas emissions becoming more and more serious, energy saving and consumption reduction and reduction of CO2 gas emissions have become the common goals 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%. Energy conservation regulations, energy conservation has been taken as a basic national policy. Among them, glass consumes the most energy in buildings. The glass area accounts for 10%-15% of the total building area, and the heat dissipation through glass reaches 70%. Ordinary glass is far from enough to block infrared and ultraviolet rays. People have taken various measures to solve the problem of glass heat insulation, such as using heat insulation film, heat reflec...

AI Technical Summary

Problems solved by technology

Ordinary glass is far from enough to block infrared and ultraviolet rays. People have taken various measures to solve the problem of glass heat insulation, such as using heat insulation film, heat reflective film, LOW-E glass, insulating glass, etc., but its energy-saving heat insulation The performance still cannot meet the requirements, and some even cause secondary light pollution, or cannot be applied to the energy-saving renovation of existing architectural glass due to complex processes and high operating costs.
