Flame-retardant noise-reduction battery label film and manufacturing method thereof

Abstract

The invention discloses a flame-retardant noise-reduction battery label film and a manufacturing method thereof, and relates to the technical field of battery label films, the flame-retardant noise-reduction battery label film comprises the following raw materials in parts by weight: 6-8 parts of PU2, 9-11 parts of ZR01, 25-35 parts of butanone, 155-185 parts of ethyl acetate, 90-110 parts of SK-360 polyurethane, 90-110 parts of PT-04C waterborne polyurethane, 1-3 parts of S-40 isocyanate crosslinking agents, 13-17 parts of absolute ethyl alcohol; 13-17 parts of distilled water, 45-55 parts ofethyl acrylate, 40-50 parts of methyl acrylate, 3-7 parts of a powder flame retardant, 1.1-1.5 parts of polyisocyanate and 5-15 parts of toluene, wherein the number of anilox lines of the micro-concave coating head is 60. When the damping material is directly applied to a certain surface, energy of solid vibration can be dissipated in the damping layer, noise emission of the surface is reduced, agood noise reduction effect is achieved, noise can be obviously reduced by wrapping a notebook computer battery for an oscillation test, and under the action of a cross-linking agent, noises can be reduced through polyurethane in the surface treatment layer. A compact film layer is formed through reaction, and the effects of sideslip prevention, printability and scratch resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of battery label films, in particular to a flame-retardant and noise-reducing battery label film and a manufacturing method thereof. Background technique [0002] A battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current, and is a device that converts chemical energy into electrical energy. It has a positive pole and a negative pole. As technology advances, batteries generally refer to small devices that can generate electricity. Such as solar cells, the performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as the energy source can obtain stable voltage, stable current, stable power supply for a long time, and a current that is little affected by the outside world, and the battery structure is simple, easy to ca...
