Abstract:
A release film is provided for supporting an ultrathin ceramic green sheet having a thickness of 0.5 to 1.0 μm, and the release film due to containing modified organic particles and an antistatic agent has a slippery releasing surface with a low friction coefficient and hence excellent coatability and releasing properties; resulted in that when the release film is rolled up, the rolled surfaces do not adhere to each other, and when the ultrathin ceramic green sheet is peeled off from the release film, the ultrathin ceramic green sheet due to a relatively small electrostatic force being generated is without breaking; so that the release film contributes to increasing the yield of ultrathin ceramic green sheet.
Abstract:
A waterborne coating consists in an ink-absorbing spheres emulsion containing acrylate micro-sphere formed with a hollow chamber, an inorganic ink-absorbing material worked with the ink-absorbing spheres emulsion together for use in absorbing ink, a waterborne acrylate emulsion containing a low-Tg acrylate monomer liquid to fix the inorganic ink-absorbing material, and a waterborne crosslinker having two or more reactive functional groups to bridge with carboxyl monomers; and particularly the waterborne coating is coated onto synthetic paper as a surface coating to endow the synthetic paper with good printability, coating adhesion, water resistance, scrape resistance and solvent resistance.
Abstract:
A low-VOC-emission waterborne coating is prepared from a waterborne acrylic emulsion, a hydrophilic cross-linking agent, a coalescing agent, additives and a pigment, and the waterborne acrylic emulsion is formed from performing emulsion polymerization on those reactive monomers including an alkyl-group-containing methyl acrylate, a hydroxyl-group-containing methyl acrylate, a carboxyl-group-containing methacrylic acid, a hydroxyl-group-containing acrylic polyester (polyether) polyol, and a methyl acrylate containing alkene-based unsaturated functional groups, which features high hardness, good adhesion, high luster, high acid resistance, high alkali resistance, good weatherability, high solvent resistance, high scrap resistance and high thermal shock resistance.
Abstract:
A process for preparing aqueous polyurethane solvent-free uses an acrylate monomer instead of acetone to dilute a prepared polyurethane prepolymer, not only the monomer can be added without cooling, but also the prepolymer has good dispersal and is favorable to subsequent dispersion in water while preventing coagulation and acetone residual; additionally, the invented process let the aqueous polyurethane become modified by acrylic grafting may improve the aqueous polyurethane being excellent in terms of mechanical strength, heat resistance and water resistance.
Abstract:
A transparent heat-shielding material having a chemical formula CsXNYWO3-ZClC, characterized by being co-doped with elements of different groups in the periodic table, wherein Cs is cesium; N is tin (Sn) or antimony (Sb) or bismuth (Bi); W is tungsten; O is oxygen; and X, Y, Z, and C are positive numbers satisfying the following conditions: X≦1.0, Y≦1.0, Y/X≦1.0, Z≦0.6, and C≦0.1; the transparent heat-shielding material is used to make a highly transparent and highly effective heat-shielding film which can be adhered to glass panels of buildings and automobiles to block infrared radiation in the wavelength range of 800-2000 nm, thereby insulating heat and saving energy; and the film is also applicable as a composite substrate for electronic components.
