Adhesive polyethylene compositions and multi-layer laminated films using the same

Disclosed is a specific adhesive polyethylene composition comprising [1] a modified ethylene/alpha-olefin copolymer resin or elastomer obtained by modifying a specific ethylene/alpha-olefin copolymer resin or elastomer, each of which comprises ethylene and an alpha-olefin of 3 to 20 carbon atoms, with an unsaturated carboxylic acid or anhydride, ester, amide, imide or metallic salt derivative of a unsaturated carboxylic acid thereof, [2] an unmodified ethylene/alpha-olefin copolymer resin and/or an unmodified ethylene/alpha-olefin copolymer elastomer and [3] a tackifier. Also disclosed is a multi-layer laminated film of 3 or more layers in which a layer of the above composition is interposed between an ethylene polymer layer and either a polyamide resin layer, an ethylene/vinyl alcohol copolymer layer or a layer of a mixture of polyamide resin and ethylene/vinyl alcohol copolymer. The adhesive polyethylene composition shows excellent adhesion strength to ethylene polymers, polyamide resins and ethylene/vinyl alcohol copolymers, high heat-sealing strength and heat resistance. The multi-layer laminated film shows excellent strength, heat resistance and gas barrier properties, and besides this film has heat shrinkability, so that the film is suitably used as a shrink film.

Anode lead plaster of power lead-acid storage battery polar plate

The invention discloses anode lead plaster of power lead-acid storage battery polar plate, and the anode lead plaster comprises the following components in proportion by weight: 1000 lead powder, 1.5 to 4 antimonous oxide, 0.8 to 1.8 stannous mono-sulphate, 1 to 2.5 aquadag, 0.68 to 0.8 conductive fiber, 25 to 40 lead tetraoxide, 80 to 96 dilute sulfuric acid and 1 to 4 silicon dioxide. The gas-phase silicon dioxide capable of increasing the viscosity strength of active substances and the conductive fiber capable of enhancing the conductive capacity of the polar plate are added, an optimum effect can be reached by adjusting the proportion of the two additives and other additives, so that under the situation of identical mass of the active substances and identical structure of a grid, the circulation service life of a power lead-acid storage battery can be improved by 28 percent, and the battery capacity of the power lead-acid storage battery can be improved by 10 to 15 percent.
