Embodiment 1

[0022] A method for preparing a high temperature and scratch-resistant PI battery label material, characterized in that it comprises the following steps:

[0023] (1) Synthesis of modified polyurethane resin, the first stage is to add reactive acrylamide, 2,6-dicarboxynaphthalene, acetic anhydride, and conduct chemical crosslinking reaction with polyurethane resin at 120 ° C; the second stage is the internal addition stage , the temperature is 200°C, the stirring speed is 120 rpm, until no acid is distilled out; the high temperature resistant glue is a commercially available epoxy resin high temperature resistant glue. The mass ratio of reactive acrylamide, 2,6-dicarboxynaphthalene, acetic anhydride, and polyurethane resin is 5:5-5.5:8-10:200. In the internal addition stage, the temperature is 200° C., and the stirring speed is 120 rpm.

[0024] (2) Use a stirring device to add the isocyanate hardener into the modified polyurethane resin and stir evenly, and the proportioning...

Abstract

The invention provides a high-temperature-resistant scratch-resistant PI battery label material and a preparation method thereof. The high-temperature-resistant scratch-resistant PI battery label material comprises a scratch-resistant resin coating, a PI polyimide film, high-temperature-resistant glue and a release film from top to bottom, wherein the scratch-resistant resin coating is prepared from modified polyurethane resin, isocyanate, ethyl acetate and anhydrous toluene; the preparation method of the modified polyurethane resin comprises the following steps: in a first stage, adding reactive acrylamide, 2,6-dicarboxyl naphthalene and acetic anhydride, and carrying out a chemical crosslinking reaction with polyurethane resin; and in a second stage as an internal adding stage, discharging acid through high-temperature stirring.

Description

technical field [0001] The invention belongs to the field of film materials, and in particular relates to a high-temperature-resistant and scratch-resistant PI battery label material and a preparation method thereof. Background technique [0002] As the market develops faster and faster, everyone's demand and requirements for products are getting higher and higher. It is necessary for a product to have more prominent advantages at the same time, but most of the products in the PI product market currently have problems such as non-scratch-resistant surfaces and non-printable surfaces. Therefore, in order to make the battery label simpler and more convenient, this product is specially developed. Contents of the invention [0003] The invention provides a PI battery label material with impact resistance, high temperature resistance and scratch resistance and a preparation method thereof, by modifying the surface coating (oily polyurethane) (introducing acrylamide functional ...
