Disclosed is a method for preparing hollow glass microbeads with a high floatation rate, and the production process and steps thereof comprising: 1) preparation of a slurry: accurately weighing the components of basic raw materials, a stable dispersant and a surfactant, wherein the components of the basic raw materials are quartz, borax, calcium carbonate, sodium carbonate, sodium sulfate, and sodium phosphate; 2) preparation of a precursor; 3) preparation of hollow glass microbeads; and 4) surface modification. The stably dispersed slurry prepared by the method of the present invention has a high solid phase content, and low surface tension and viscosity, such that the energy consumption of spray granulation is not only significantly decreased, but also the prepared precursor has a small particle size span and uniform composition. In combination with a high-temperature negative-pressure vitrification process, the hollow glass microbeads are enabled to have a floatation rate of higher than 96.5% and a high surface finish, and furthermore, the hollow glass microbeads are strengthened by using low-temperature circulating wind. The raw materials of the present invention are easily available, the conglomeration rate of the hollow glass microbeads is high, and the present invention is simple in technological process, and low in energy consumption and production cost, and the product has a wide range of application.
A: Disclosed are a structural sealant for a glass curtain wall and a preparation method therefor. A formula of the structural sealant comprises: hydroxyl-terminated polydimethylsiloxane, acrylic acid, aconitic acid, polypropylene powder, bis(3,4-diphenylmethylene)sorbitol, trimethoxyboroxine, 2-amino-N-cyclohexyl acetamide, vinyl tris(methylethylketoximino)silane, ethylene glycol glycidyl ether, dibutyltin mercaptide, a hollow glass bead, Methyltris(methylethylketoxime)silane, 3-triethoxysilylpropylamine, dibutyltin dilaurate, ammonium persulfate, ferric acetylacetonate, sodium silicate, dimethylbenzylcarbinyl acetate, pentaerythritol, and fluorocarbon resin FEVE. The present invention has the following beneficial effects: the structural sealant in the present invention is excellent in mechanical strength, does not need base coat, and has good cohesiveness, excellent comprehensive performance, good aging resistance and high displacement capability. The structural sealant has excellent flame resistance, and a small amount of flame retardant is added, so that the influence on comprehensive performances of the sealant is small.
B: A low-density conductive polypropylene composition, comprising the following components in parts by weight: 80-90 parts of PP resin, 5-15 parts of hollow glass beads, 3-8 parts of MWCNT, and 0.1-3 parts of an auxiliary agent. The selection of hollow glass beads as a dispersing component effectively improves the dispersion of MWCNT in the polypropylene system, so that the surface resistance of the prepared material is in the range of 104-10 2 Ω/sq; in addition, due to the low density of the hollow glass beads, the material exhibits low-density characteristics. Also disclosed are a preparation method for the low-density conductive polypropylene composition, and an application thereof.
C: An energy-saving thermal insulation material for use in buildings and a preparation method therefor. The thermal insulation material is made of the following raw materials in parts by weight: 30-50 parts of light stucco stone, 13-20 parts of expanded perlite, 7-13 parts of light calcium, 10-15 parts of methyl fiber, 9-15 parts of sepiolite, 5-8 parts of diatomite, 3-6 parts of fibrous brucite, 10-15 parts of plant fiber extract, 1-4 parts of 2-maleate monobutylate, 2-3 parts of 1,2,3-glycerol monooctadecyl ester, 1-3 parts of lithium citrate, 2-5 parts of hollow glass microspheres, 3-6 parts of sodium lignosulfonate, 1-3 parts of sodium silicate, 2-4 parts of magnesium oxide, 1-4 parts of n-octanol, 1-2 parts of isocyanate, 1-2 parts of hydrogenated chlorofluorocarbon, 3-8 parts of a water reducing agent, 1-4 parts of a foaming agent and 2-6 parts of a stabilizer.
