Abstract

The invention discloses a sound-attenuation damping flame-retardant plane material and a manufacturing method thereof. The sound-attenuation damping flame-retardant plane material comprises a coating, a first plane material layer, a glue layer and a second plane material layer which are sequentially arranged from top to bottom, wherein the glue layer is glue. The sound-attenuation damping flame-retardant plane material is characterized in that the first plane material layer and the second plane material layer are both made of PET, the glue is formed by mixing a component A and a component B, the ratio of the component A to the component B is 1: (0.8-1), and the component A comprises 30%-45% of butyl acrylate, 10%-15% of propylene isooctyl ester, 1.5%-3% of acrylic acid, 0.1%-1% of hydroxyethyl acrylate, 45%-55% of ethyl acetate and 0.05%-0.2% of an initiator; and the component B comprises 10%-25% of tackifying resin, 10%-25% of butyl rubber, 20%-35% of flame-retardant powder and 50%-65% of methylbenzene. The preparation method comprises the following steps of firstly, mixing the component A, then adding the materials in the component B into the component A, mixing, and then gluing and pasting. The damping, flame-retardant and noise-reducing performance of the plane material is achieved, vibration and noise are small, and the flame-retardant effect is good.

Description

technical field [0001] The invention relates to a label, in particular to a sound-absorbing, damping, and flame-retardant surface material and a manufacturing method thereof. Background technique [0002] After the battery is manufactured, it is generally necessary to include a label on its surface for labeling. Wherein, when the battery is in use, due to shaking and vibration, the label film coated on the surface of the battery will vibrate and generate noise, which affects the user experience, and its flame retardancy is not good. Therefore, how to solve the above technical problems is the direction that those skilled in the art need to work on. Contents of the invention [0003] The purpose of the present invention is to provide a sound-absorbing, damping, flame-retardant surface material and its manufacturing method. By using the structure and manufacturing method, it can effectively play a shock-absorbing effect, and the product is less prone to noise when vibrating,...
