Abstract:
A method for lithium aluminum film packaging materials, with water, high temperature and corrosion resistance, the substrate layer, and then layer, aluminum foil layer, anti-corrosion layer, adhesive layer and the inner layer together constitute from the outermost to innermost layer laminate structure in which one side of the aluminum foil layer, or both side surface of the conductive coating material to said coating and curing anticorrosive layer, and the use of fluorine-containing polyurethane resin constituting the laminated rubber layer and the inner layer of corrosion between the adhesive layer, used lithium batteries as plastic film packaging applications, it can promote lithium battery with Merit water resistance, high temperature resistance and corrosion resistance, and enhance the use of lithium batteries in years.
Abstract:
A weather-resistant crosslinked polyolefin composition is a novel formula containing a comprehensive mixture constituted by crosslinking agent, antistatic agent, TiO2 sized in nanometer and TiO2 sized in micrometer and essential components including polyolefin composition resin, lubricant auxiliary crosslinking agent, antioxidant, UV absorber and filler etc; this novel formula is particularly suited to produce a weather-resistant crosslinked polyolefin sheet with a calender machine instead of an extruder conventionally used, and the polyolefin sheets produced thereof are excellent in both heat-resistant and weather-resistant as well as in a high-quality sheet surface and capably made at a high yield rate through the calender machine.
Abstract:
An aluminum plastic film for a lithium battery and a method for manufacturing the same are provided. The method includes steps as follows: preparing a polyolefin adhesive; coating the polyolefin adhesive onto one surface of an aluminum foil layer; disposing an inner polyolefin layer onto the polyolefin adhesive; and drying the polyolefin adhesive, so that a polyolefin adhesive layer is formed between the aluminum foil layer and the inner polyolefin layer. Components of the polyolefin adhesive include a modified polyolefin polymer and a hardener. The modified polyolefin polymer has a modified group, a structure of the modified group contains maleic anhydride, and a molecular weight of the modified polyolefin polymer ranges from 100,000 g/mol to 200,000 g/mol.
Abstract:
A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of CsXNYWO3-ZClC and having a particle size of 0.005-2 μm, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.
Abstract:
An aluminum plastic film packaging material for lithium batteries to prolong service life, at least comprising an inner layer and an aluminum foil layer, is performed an anti-corrosion treatment between the inner layer and the aluminum foil layer by one of the following ways: 1) a chromium-containing anti-corrosion layer is formed from an aqueous modified resin containing trivalent chromium; and 2) an adhesive layer with non-chromium material is formed from an aqueous modified resin, an epoxy curing agent, a silane coupling agent and a nano-sized metal oxide particle.
