Problems solved by technology

[0005] However, after the above-mentioned adhesives and most acrylic adhesives in the prior art are bonded to the carrier, they are not easy to separate from the carrier. If separation is required, the label will be torn, which has poor peelability.

Abstract

The invention discloses an acrylic ester adhesive and a preparing method thereof. The defect that an acrylic ester adhesive is bad in stripping resistance is overcome. The acrylic ester adhesive is characterized by being prepared from A components and B components, wherein the weight ratio of the A components to the B components is 1:1; the A components are prepared from metacrylic acid ester, methacrylic acid, modified ethylene propylene diene monomer, phenolic inhibitor, antioxidant, solvent, A-type accelerant, assistant and thickening filler; the B components are prepared from metacrylic acid ester, methacrylic acid, methyl vinyl silicone rubber, phenolic inhibitor, solvent, B-type accelerant, coupling agent and thickening filler; as the modified ethylene propylene diene monomer is contained in the A components, the whole structural performance of the A components can be enhanced, whole stripping is facilitated during stripping, and the stripping resistance of the A components is improved; as the poly-methyl vinyl silicone rubber is contained in the B components, the integration structural performance of the B components can be remarkably increased, and the stripping resistance of the B components is improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to an acrylate-based adhesive and a preparation method thereof. Background technique [0002] Labels are printed materials used to identify relevant instructions, and have been widely used in production and life. For example, labels about product instructions are printed on various products and equipment. People can understand product names and performance by seeing these instructions. Understand the name of the equipment, how to use it, etc., and play a good role in prompting and guiding. [0003] Usually, the label is coated with glue on its back and bonded to the carrier. This method has been gradually replaced by a two-component adhesive. The two-component adhesive is to apply part of the glue on the label and the other part of the glue on the carrier. , and then put the two parts of the glue together for reaction. During the production process, it was found that the two-component adhesive has ex...
