Abstract

An embodiment of the invention provides a complex adhesive and a preparation method thereof. The method comprises the steps as follows: raw materials including, in percentage by weight, 58%-62% of anacrylic emulsion, 23%-27% of rosin resin, 10.5%-14.5% of alcohol and 0.5%-4.5% of a crosslinking agent in percentage by weight are provided, then, the rosin resin is dissolved with the alcohol, dissolved rosin resin is obtained, next, the dissolved rosin resin is added to the acrylic emulsion, a mixed solution is obtained and stirred uniformly, finally, the crosslinking agent is added to the mixedsolution, the mixture is stirred continuously, and the complex adhesive is obtained. The complex adhesive is simple to prepare, good in compatibility, stable in state and good in loading fastness effect.

Description

technical field [0001] The present application relates to the technical field of composite glue, in particular to a composite glue and a preparation method thereof. Background technique [0002] Composite glue is one of the very common glues in industrial production. High-performance composite glue has strong adhesion to various films. It is usually used for laminating and compounding thick and thin layers of materials, especially for some difficult-to-stick Film substrates, such as PVC, PET, aluminum foil, silver foil, thick layer PE, etc. have better bonding effect, and have the advantages of fast curing, strong initial bonding strength, excellent peel strength and high temperature resistance. [0003] An existing composite glue is composed of the following components according to mass percentage: 89.5%-90.5% of modified copolyester resin, 4.75%-5.25% of toughening agent, 3.8%-4.2% of tackifier, slip agent 0.95% to 1.05%. Another existing composite glue. The preparation...
