Abstract:
A transparent polyester film has low visible light transmittance of 5-50% by JIS K7705 testing standard and a high infrared-blocking rate of at least 90% by JIS R3106 testing standard, which is extruded from a kind of polyester resins obtained from 5-40 wt % of nanoparticle-based thermal insulation slurry and/or 0.005-0.1 wt % of nanoparticle-based black pigment slurry by weight of and to react with the polymerization materials to completely perform an esterification and a polycondensation, wherein the thermal insulation nanoparticle has a chemical formula of CsXNYWO3-ZClC with an average particle size of 10-90 nm and the nanoparticle-based black contains carbon black particles having a particle size of 20-80 nm.
Abstract:
An optical film, a method for manufacturing the same, and a backlight module are provided. The optical film is formed by a cadmium-free quantum dot gel layer, which includes a first polymer and a plurality of cadmium-free quantum dots dispersed therein. The first polymer includes: 1 wt % to 5 wt % of a photoinitiator; 3 wt % to 30 wt % of scattering particles; 10 wt % to 40 wt % of a thiol compound; 5 wt % to 30 wt % of a monofunctional acrylic monomer; 5 wt % to 20 wt % of a bifunctional acrylic monomer; 10 wt % to 40 wt % of a multifunctional acrylic monomer; 5 wt % to 20 wt % of an organosilicon grafted oligomer; and 100 ppm to 2,000 ppm of an inhibitor. The thiol compound includes a primary mercaptan and a secondary mercaptan, and a weight ratio of the primary mercaptan to the secondary mercaptan ranges from 1:3 to 3:1.
Abstract:
A waterborne heat-insulation coating uses a silicon dioxide dispersion with silicon dioxide evenly dispersed in resin through a sol-gel method as a heat-insulation agent; since the silicon dioxide dispersion has great fineness and large specific surface area of between 30.1 and 100 m2/g, the waterborne heat-insulation coating when applied to building surfaces forms a coating layer that features a packed structure, a smooth surface, and a high surface reflectivity of 85% or more; resulted in that the coating layer can effectively block infrared rays and provide excellent thermal shielding effects, stain resistance, and durability.
Abstract:
A transparent ultraviolet curable adhesive is a solventless composition, based on a total weight of the composition, being composed of 35-65 wt % of a polyurethane (meth)acrylate resin, 30-60 wt % of a (meth)acrylate monomer, 0.1-5 wt % of an acrylate group-containing bisphenol fluorene derivative, 0.3-8 wt % of a photopolymerization initiator and 0.002-0.01 wt % of a vinyl silane coupling agent; and, the adhesive if cured has a refractive index of 1.52-1.56 very close to 1.52 for a glass thereof and has a visible light transmittance of 93-99 VLT (%) so suitable to be adhered to displays, transparent conductive film and touch panels.
Abstract:
A polishing pad for surface planarization is made by impregnating a polyester-based fibrous fabric with thermosetting resins to form a porous impregnated material, and heating the porous impregnated material to effect changes in shape of the pores such that an integrally formed polishing pad with hard/soft layers of different hardnesses is obtained; the heated side of the polishing pad has high hardness and high cutting/grinding ability, whereas the unheated side maintains the original tiny pores and low hardness; and the polishing pad can produce a buffering effect when subjected to an external force and in turn apply an evenly distributed force to an article being polished.
