Problems solved by technology

Among them, in the field of packaging, barcodes are the most common information recording method. When shopping in shopping malls and supermarkets, you can scan product barcodes to query product information and settle products. However, scanning barcodes requires scanning the product one by one. It is a waste of time to obtain the information of each product, and the recorded information is single, and the user cannot obtain more information about the production process

Abstract

The invention relates to an adhesive material with an information recording function. The adhesive material comprises components as follows: 25%-97% by mass of an adhesive and 3%-75% by mass of an information recording material, wherein the adhesive is a thermoplastic hot melt adhesive, and the information recording material is a magnetic recording material or a photopolymer recording material. The adhesive material with the information recording function is good in liquidity and high in information recording performance during use; the viscosity of the adhesive material prepared from 25% of a BaFe12O19 magnetic recording material and 75% of an ethylene-vinyl acetate copolymer based thermoplastic hot melt adhesive is 660 mPa.s, and the residual magnetic flux density and the coercivity can reach 2800 Gs and 1250 Oe respectively; the viscosity of the adhesive material prepared from 60% of an acrylate-based photopolymer recording material and 40% of the thermoplastic hot melt adhesive with a rubber-based polymer as a matrix is 1600 mPa.s, the diffraction efficiency is 84%, and the photosensitivity is 40 mJ / cm<2>.

Description

technical field [0001] The present invention relates to a colloidal material, a preparation method and an application, in particular, to a colloidal material with an information recording function, a preparation method and an application. Background technique [0002] Colloidal materials have been widely used as bonding materials in various fields, especially in the field of packaging, where sealing, labeling and other processes require the use of colloidal materials to bond products, but the current colloidal materials are only used between items. The bonding between them has a single purpose, resulting in a waste of some resources. At the same time, with the development of information technology, information acquisition methods such as magnetic cards, chips, and barcodes have become an indispensable part of our daily life. Among them, in the field of packaging, barcodes are the most common information recording method. When shopping in shopping malls and supermarkets, you...
