Coating material for electrical equipment, method for manufacturing coating material for electrical equipment, and closed insulating device
There are provided a coating material for electrical equipment, a method for manufacturing a coating material for electrical equipment, and a closed insulating device, capable of suppressing floating and moving around of foreign substances in electrical equipment. A coating material for electrical equipment 20 in an embodiment includes: a matrix resin 50 composed of an epoxy resin; a first filler 10 dispersedly contained in the matrix resin 50 and composed of whiskers having a semiconductive specific volume resistivity; a second filler 30 dispersedly contained in the matrix resin 50 and composed of particles having a semiconductive specific volume resistivity; and a third filler 40 dispersedly contained in the matrix resin 50 and composed of a planar, fibrous, or lamellar substance having insulating properties.
SURFACE COATINGS AND METHODS
Provided herein include methods and compositions pertaining to coatings, such as paints, for covering a substrate. In some aspects and embodiments the coatings may include a heat reflective metal oxide pigment that, applied to an external surface of a building (or is applied on a substrate used for an external surface of a building such as an architectural metal panel, EIFS, as a stucco top coat or as a top coat for roofing tiles) reduces the energy consumption in the building. In other aspects and embodiments, provided are textured coatings having a texturing material; for example, methods and compositions are provided pertaining to textured coatings that can be applied robotically or in an automated fashion. In various aspects and embodiments, textured coatings are provided that include a texturing material and a heat reflective metal oxide pigment. In some aspects and embodiments heat reflective coatings for concrete or clay tiles and methods of applying such are provided.
Environmentally Friendly Colorant Compositions and Latex Paints/Coatings
The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.
PHOTOTHERMAL-CURING RESIN COMPOSITION, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Some embodiments relate to a photothermal-curing resin composition, and a preparation method therefor and the use thereof. The resin composition includes a combination of specific parts of a prepolymer, a monomer, a photoinitiator, a thermal initiator, fumed silica and a glass powder. By means of adding specific parts of the photoinitiator in conjunction with the thermal initiator, the completion rate of a curing reaction is increased, the resin composition is more thoroughly cured, and the residual monomer rate after curing is lower, and specific parts of the fumed silica and barium-containing glass powder are further added as fillers, such that the hardness, strength and wear resistance of the resin composition are effectively enhanced; therefore, a product resulting from the 3D printing of the finally obtained resin composition completely meets the requirements for being used as temporary crowns and bridges.
THERMOSENSITIVE PAPER
The present invention relates to a coated paper article with an intermediate basecoat layer comprising high void fraction porous hollow sphere polymer particles (HSPs). HSPs with very small pore area density and high void fraction result in increased optical density at a given print energy in thermal printing applications.
POLYCARBONATE ALLOY MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
A polycarbonate (PC) alloy material includes the following components in parts by weight: 40-70 parts of polycarbonate, 20-40 parts of polyethylene terephthalate (PET), and 0.1-2 parts of a metallic compound. The metallic compound is selected from any one or more of a metal oxide, a metal alkali or a metal salt. The metal is selected from any one or more of copper, iron, magnesium, calcium, titanium, antimony, sodium or potassium. A certain amount of PET and a specific metallic compound are added to the polycarbonate; the prepared polycarbonate alloy material has excellent chemical resistance, and meanwhile has a high melt strength and a low melt cooling rate, and thus is suitable for the production of large thick-walled packaging container products via extrusion blow molding.
FUNCTIONALLY GRADED POLYMER ARTICLES AND METHODS OF MAKING SAME
Disclosed herein are methods for manufacturing a functionally graded polymer material. A method comprises preparing a melted polymer mixture comprising a thermoplastic polymer and a magnetic filler; molding the melted polymer mixture; and applying a magnetic field to a portion of the melted polymer mixture to form the functionally graded article, wherein as the melted polymer mixture flows into the mold, the melted polymer mixture comes into contact with the magnet field. Another method comprises molding the melted polymer mixture; and applying a magnetic field from a first magnet to a first portion of the melted polymer mixture and applying a magnetic field from a second magnet to a second portion of the melted polymer mixture to form the functionally graded article, wherein the first magnet and the second magnet are positioned in a manner such that the magnetic field produced by each are nonoverlapping.

Build Materials Having A Metallic Appearance For 3D Printing
In one aspect, composite build materials for use with a 3D printing system are described herein. In some embodiments, a composite build material described herein comprises a carrier ink comprising a curable material; and pigment particles dispersed in the carrier ink, wherein the pigment particles comprise mica. In some cases, the carrier ink is present in the composite build material in an amount of about 80-98% by weight, and the curable material comprises one or more species of monomeric and/or oligomeric (meth)acrylates. Additionally, in some instances, the pigment particles are present in the composite build material in an amount of about 2-8% by weight and comprise up to about 85% by weight mica, based on the total weight of the pigment particles. The pigment particles, in some cases, can also comprise TiO.sub.2 and/or Fe.sub.2O.sub.3.
