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.

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.
