Low-haze transparent conductive film and preparation method thereof

The invention provides a low-haze transparent conductive film and a preparation method thereof. The low-haze transparent conductive film comprises a transparent substrate layer, wherein the transparent substrate layer is coated with a super hydrophilic coating formed by a super hydrophilic coating material, the super hydrophilic layer is coated with a transparent conductive layer formed by a conductive ink composition, and the wetting angle of water at the surface of the super hydrophilic coating is less than or equal to 5 degrees. After the super hydrophilic coating is coated, the light transmittance of the substrate is improved, the haze is reduced, an adhesive force between the transparent conductive layer and the substrate is enhanced, and the oxygen permeability of the transparent substrate is also reduced at the same time. By adopting the technical scheme provided by the invention, the total haze of the ultimately acquired transparent conductive film is reduced by 40% compared with that before super hydrophilic processing under the condition of keeping the conductivity to be unchanged, the light transmittance is improved by 2-5%, the adhesive force is also obviously improved, and the appearance is more transparent.

Reaction-type transparent halogen-free flameproof unsaturated polyester and preparation method thereof

The invention discloses a method for preparing a reaction type transparent halogen-free flame retardation unsaturated polyester. A program temperature control melting polycondensation reaction method is adopted; C2-6 dihydric alcohol, C3-8 saturated binary acid or anhydride, C4 unsaturated binary acid or anhydride, and a difunctional reactivity phosphatic flame retardant are used to synthesize an unsaturated polyester oligomer; styrene is taken as a crosslinking agent to prepare the unsaturated polyester which can be solidified at room temperature with transparent appearance, moderate viscosity and lower cost. After solidification, no added dissociated flame retardant component is contained in the cross linked network of the unsaturated polyester. The mechanical property, the flame retardation property and the electricity property of the product can be stable in a long period, the oxygen index of the product can be increased from 19 to 29 percent, and the product can pass the vertical firing UL94-V0 level. The reaction type transparent halogen-free flame retardation unsaturated polyester can be applied to the field of electronic and electric appliance insulating materials with higher performance requirements, construction flame retardation coating, ship-building material, flame retardation fiber glass reinforced plastics, and the like.

T-shaped range hood with multiple layers of oil fume separation meshes

The invention provides a T-shaped range hood with multiple layers of oil fume separation meshes. The T-shaped range hood comprises a housing, an external oil fume separation mesh, a middle oil fume separation mesh, an internal oil fume separation mesh, an oil cup, a motor, a volute with a motor bracket, double worms, a smog sensor and other range hood assemblies, wherein the external oil fume separation mesh is of an inverted pyramid shape, the middle oil fume separation mesh is in a plane shape, the internal oil fume separation mesh is in an M shape, and the three oil fume separation meshes form a wrapping progressive space. In light of a principle of fluid dynamics, a huge negative pressure region is generated to collect oil smoke deeply, the resistance is reduced when the oil fume rises and the exhaust air quantity is increased; the smog sensor senses smog to automatically adjust the motor to rotate so as to adjust the suction of the range hood. The T-shaped range hood sucking and exhausting the oil fume has the functions of quickly sucking the oil smoke and automatically adjusting wind power, avoids the risk that the working performance of the range hood is affected as the oil fume is unsmooth to suck and exhaust when the oil fume in the raising process blocks the smoke meshes, and improves the performance of the T-shaped range hood in the oil fume suction and exhaust.

Preparation method of nanometer silica polyether (ester) polyol dispersion for modifying polyurethane

The invention provides a preparation method of a nanometer silica polyether (ester) polyol dispersion for modifying polyurethane. The method adopting precipitation and extraction combination comprises the following steps: preparing a nanometer silica dispersion by using alkali metal silicate under acid catalysis or other strong acidic and strong acid weak alkali salt double hydrolysis conditions, carrying out wrapping modification through a coupling agent, adding a corresponding strong acid strong alkali salt until the obtained solution is supersaturated, extracting nanometer silica from the obtained aqueous solution by using a low boiling point solvent, adding polyether (ester) polyol, mixing, and carrying out reduced pressure distillation at 80DEG C under an absolute pressure of below 0.010MPa to remove the low boiling point solvent and obtain the uniform nanometer silica polyether (ester) polyol dispersion. The dispersion can be used as a polyurethane modifier to improve the hardness, the toughness, the compactness, the antifriction property and the like of a film. The preparation method of the nanometer silica dispersion has the advantages of simplicity, cheap and easily available raw materials, low cost, and suitableness for large-scale industrial production.
