Background

In the technical field of doors and windows, the design concept of the doors and windows is developed towards the directions of convenient assembly and disassembly, environmental protection and energy conservation. Among various energy consumption, the building heating and air conditioning energy consumption occupies a considerable proportion.

The energy-saving glass mainly applied at present is Low-E glass, also called Low-emissivity coated glass, and has good energy-saving effect and most application. However, the glass needs to be made into a double-layer hollow glass to keep the energy-saving effect, so the glass is expensive in manufacturing cost and high in foundation requirement, and the double-layer glass is easy to discard due to the fact that the double-layer glass is not tightly sealed. Therefore, a healthy door and window which can preserve heat and is convenient to install is urgently needed.

The invention has the beneficial effects that:

1. according to the constant-temperature health door and window, the door and window frame body and the door and window sash are connected through the door and window shaft, the door and window sash can rotate along with the rotation of the door and window shaft, and inward or outward bidirectional opening can be achieved. When the door and window needs to be moved or replaced, only the movable clamping plate needs to be opened, and the door and window sash with the door and window shaft is taken out, and the door and window can be installed and used again at any time after being detached. In addition, the door and window sash is coated with the heat-insulating coating, so that the problem of poor heat-insulating property of the existing door and window sash is solved. According to the invention, the sealing rubber gasket is coated on the edge of the door and window sash, and the sealing rubber gasket can seal the gap between the door and window sash and the door and window frame body after the door and window are closed, so that the heat preservation and insulation effects of the door and window are further enhanced.

2. The polymethyl methacrylate used in the heat-insulating material prepared by the invention has excellent optical property, insulativity, processability and weather resistance; the modified nano tin antimony oxide has stronger heat preservation and insulation effects; benzotriazole is used as antifogging agent and stabilizer for preventing atomization.

The polymethyl methacrylate has the defects of brittleness, easy cracking and low surface hardness when being used independently, and the defects of surface hardness and brittleness, easy cracking are greatly improved after being compounded with the modified nano tin antimony oxide prepared by the invention.

3. The modified nanometer tin antimony oxide is obtained by compounding strontium germanate microspheres and nanometer tin antimony oxide, the nanometer tin antimony oxide has better light transmission and stronger heat insulation performance, but the dispersity is poorer and is easy to precipitate. Firstly, germanium dioxide and strontium acetate are adopted as a germanium source and a strontium source for preparing the strontium germanate microspheres, and the finally obtained strontium germanate microspheres are composite oxides with cubic spinel structures, and have rich apertures and uniform arrangement. Secondly, the prepared strontium germanate microspheres are firstly sulfonated and activated by dimethyl sulfonate and then are adsorbed and grafted with the nano tin oxide antimony, so that the strontium germanate microspheres can adsorb and graft more nano tin oxide antimony, and the obtained modified nano tin oxide antimony is more stable.

In addition, the strontium germanate microspheres and the antimony tin oxide play a complementary role. The antimony tin oxide and the strontium germanate microspheres are transparent materials, the antimony tin oxide selectively absorbs near infrared light, the strontium germanate microspheres selectively absorb ultraviolet light, and the strontium germanate microspheres absorb most of other visible light very little, so that the good light transmittance in a visible light area can be maintained while the heat preservation and insulation effects are achieved. And because both have lower emissivity in the far infrared region, can also prevent the heat in the room from losing outwards effectively when using in the solar terms or winter that mainly heat.

4. The sealing rubber pad is made of modified ethylene propylene diene monomer rubber material. The ethylene propylene diene monomer has strong water resistance, corrosion resistance, weather resistance and high-temperature steam resistance, is very suitable for being used as a sealing material, but has poor flame retardance and poor caking property. According to the invention, the oil resistance and the flame retardance of the obtained modified ethylene propylene diene monomer rubber material are greatly improved by preparing modified polysiloxane and performing composite modification on ethylene propylene diene monomer rubber. Firstly, the polysiloxane has strong flame retardance, and the flame retardance of the ethylene propylene diene monomer is greatly enhanced after the polysiloxane is compounded with the ethylene propylene diene monomer; secondly, the invention firstly carries out functionalization on siloxane monomers, namely, the 3-mercaptopropyltriethoxysilane containing sulfydryl and the 1, 3-cyclopentadiene containing double bonds are used as raw materials to carry out click reaction of sulfydryl-double bonds to synthesize the functionalized siloxane monomers, and then the functionalized siloxane monomers are polymerized into functionalized polysiloxane under the initiation action of fluorosulfuric acid, namely the modified polysiloxane. After the prepared modified polysiloxane is compounded with ethylene propylene diene monomer, active groups on the surface of the ethylene propylene diene monomer can be increased, and the adhesion of the ethylene propylene diene monomer is enhanced.
