Embodiment 1
[0047] Tourmaline nanoparticles (average particle diameter 52nm) and silver nanoparticles (average particle diameter 30nm) (both obtained from Shanghai Langer Reagent Co., Ltd.) were dispersed in acetone to prepare a silver-doped tourmaline dispersion, wherein Relative to the weight of tourmaline, the weight of Ag nanoparticles is 1.2%, and the tourmaline dispersion contains 50 g of tourmaline particles per 1 L of acetone. Use high-speed shearing homogenizer (5000rmp) in dispersion process; Described tourmaline dispersion liquid and glycidyl ether epoxy resin / acetone solution (the content of epoxy resin in epoxy resin / acetone solution is 100g / L) Mix and stir to obtain tourmaline / glycidyl ether epoxy resin / acetone suspension; put the silver-doped tourmaline / glycidyl ether epoxy resin / acetone suspension in a drying oven at 50°C Degas for 30-60min to evaporate acetone, then add hardener (HB-2321 aliphatic amine hardener from Guangzhou Huabang Chemical Co., Ltd.) Degas again und...
Embodiment 2
[0049] Repeat Example 1, the difference between Example 2 and Example 1 is that the tourmaline particles are modified by the following method, that is, surface modification: adding nano-tourmaline particles to the APTS solution, based on the weight of the entire solution , the nano tourmaline particle content is 10.0%, the APTS content is 3.0%, the solvent of described solution is the mixed solvent (volume ratio is 1: 1: 1) that water, ethanol, THF are formed, the suspension obtained is vigorously stirred Mixing, the reaction temperature is 60°C, the reaction time is 2h, then lowered to room temperature, filtered, and dried to obtain modified tourmaline particles.
Embodiment 3
[0056] The tourmaline cloth obtained in Example 1, the fiber cloth containing germanium stone material, the lining and the lining are made into a composite fabric according to the above method, and a hat (not including the brim) is made from the composite fabric, wherein the lining Both the fabric and fabric are made of polyester, and the fiber cloth containing germanium stone material is germanium stone mesh cloth (obtained from Tianjin Duolekang Company). After testing, the far-infrared incidence rate of the composite fabric is about 91%, and the negative ion release concentration is about 1100 / cm 3 .
[0057] It can be clearly seen from the above-mentioned examples and comparative examples that the dispersion of tourmaline particles can be effectively realized by using the surfactant according to the present invention, thereby improving the breaking strength and elongation at break, while also improving the far-infrared emissivity and Negative ion release concentration. I...
