Problems solved by technology

[0003] Aluminized adhesive tape is a kind of pressure-sensitive adhesive tape. It is made of aluminized substrate and pressure-sensitive adhesive. The surface of aluminized substrate is relatively smooth. In the prior art, some glues can only temporarily solve the problem of residual glue, but with the prolongation of time, the problem of residual glue has not been perfectly solved

preparation example Construction

[0055] According to another aspect of the present invention, the preparation method of the above-mentioned pressure-sensitive adhesive comprises the steps of:

[0056] (a) Mix part of the soft monomer, all the hard monomer and the functional monomer, stir and heat, then add part of the initiator and part of the solvent to react;

[0057] (b) add remaining soft monomer to the mixture obtained in step (a) to react, heat up and react, add remaining initiator and part of solvent, keep warm;

[0058] (c) adding remaining solvent to the mixture obtained in step (b) for dilution to obtain a pressure-sensitive adhesive.

[0059] The preparation method of the pressure-sensitive adhesive in the present invention is simple and highly controllable. The product with a high glass transition temperature and the product with a low glass transition temperature are connected together to form a substance, which achieves molecular-level dispersion and dispersion effect. Well, the pressure-sensit...

Abstract

The invention belongs to the technical field of polymer materials and particularly relates to a pressure sensitive adhesive and a preparation method thereof, an aluminum coated tape and use thereof. The pressure sensitive adhesive is mainly prepared from, by mass parts, 25-75 parts of soft monomer, 5-30 parts of hard monomer, 3-10 parts of functional monomer, and 0.05-0.8 part of initiator and 40-65 parts of solvent. The method for preparing the pressure sensitive adhesive is simple and practical, and a product at a high glass transition temperature and a product at a low glass transition temperature are connected together to form a substance, which achieves molecular level dispersion and a good dispersion effect. The pressure sensitive adhesive is uniform, and the aluminum coated tape ismanufactured and adheres to a smooth steel plate. During the stripping after 60 days, still no adhesive residue occurs on the surface of a glued material, and the adhesive residue-free performance isrelatively durable.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a pressure-sensitive adhesive and a preparation method thereof, an aluminized tape and an application thereof. Background technique [0002] Pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which is mainly used in the preparation of pressure-sensitive tape, and its function is to make the tape have pressure-sensitive adhesive properties. Pressure-sensitive adhesive is a special type of adhesive that can be bonded with finger pressure without heating, solvent or other means. Generally, pressure-sensitive adhesive is not directly used for bonding, but must be applied to strips. It can only be used when various pressure-sensitive adhesive products are made on the substrate. Pressure-sensitive adhesive products include pressure-sensitive tape, pressure-sensitive adhesive label paper, and pressure-sensitive adhesive sheet. [0003] Aluminized adhesive t...
