Problems solved by technology

At present, most pressure-sensitive adhesives are mainly used for PE and PVC-based pressure-sensitive adhesives, which have poor heat resistance. When applied to PET protective films, they have poor adhesion to PET base films and tend to leave residues when peeled off. Glue and other shortcomings, can not be used as pressure-sensitive adhesive for PET protective film, and PET film itself has static electricity, which will generate static electricity when it is attached or torn off, so it is difficult to apply to electronic and electrical products that prevent static electricity.

Abstract

The invention relates to a pressure-sensitive adhesive for a PET protective film and a preparation method thereof. The pressure-sensitive adhesive provided by the invention is made from the following raw materials of: by weight, 1-20 parts of a (methyl)acrylate monomer which is used for preparing homopolymers and whose glass transition temperature ranges from minus 45 DEG C to 10 DEG C, 60-90 parts of a (methyl)acrylate monomer which is used for preparing homopolymers and whose glass transition temperature ranges from minus 90 DEG C to minus 50 DEG C, 1-20 parts of a acrylic acid monomer containing functional groups, 0.01-15 parts of a cross-linking agent, 0.01-1 part of an initiator, 0.001-5 parts of a silane coupling agent, 0.001-5 parts of a plasticizer, 0.001-5 parts of an antistatic agent, and 70-100 parts of a solvent. The pressure-sensitive adhesive for the PET protective film in the invention has characteristics of strong adaptability to the PET basement film, microviscosity, repeelable performance, high temperature resistance and antistatic property, and can be widely applied in the production of the PET protective film. The invention also provides a preparation method ofthe above pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive and a preparation method thereof, in particular to a pressure-sensitive adhesive used for PET protective films and a preparation method thereof. The invention also relates to a PET protective film prepared by using the pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] PET protective film has the characteristics of high transparency, excellent mechanical properties, heat resistance, cold resistance, chemical resistance, oil resistance, etc., and is widely used in electronic and electrical products. [0003] PET protective film is mainly made of PET film and pressure-sensitive adhesive through coating, drying, curing and other processes. Among them, the quality of pressure-sensitive adhesive plays a decisive role in the quality of PET protective film. At present, most pressure-sensitive adhesives are mainly used for PE and PVC-based pressure-sensitive adhes...
