Abstract

The invention belongs to the technical field of organosilicone pressure sensitive materials, and discloses a high stripping force PET (polyethylene terephthalate) protective film pressure sensitive adhesive and a preparation method thereof. The high stripping force PET (polyethylene terephthalate) protective film pressure sensitive adhesive is composed of the folhighing components in parts by weight: 10-30 parts of base gum; 30-50 parts of modified MQ resin; 40 parts of an organic solvent, 1-3 parts of hydrogen-containing silicone oil; 0.1-0.3 part of an inhibitor and 3-4.5 parts of a catalyst; the preparation method comprises the following steps: (1) mixing the base gum, the organic solvent and the modified MQ resin, and adding the catalyst, mixing and stirring evenly; (2) then adding the inhibitor, mixing and stirring evenly; and (3) adding the hydrogen-containing silicone oil, mixing and stirring evenly to obtain the high stripping force PET protective film pressure sensitive adhesive. The high stripping force PET protective film pressure sensitive adhesive has excellent primary viscidity and lasting viscidity, also has high stripping force, and has high economic value.

Description

technical field [0001] The invention belongs to the technical field of silicone pressure-sensitive materials, and in particular relates to a PET protective film pressure-sensitive adhesive with high peeling force and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is the abbreviation of pressure-sensitive adhesive. It is a kind of adhesive that is sensitive to pressure. It is mainly used to prepare pressure-sensitive tapes and is widely used in packaging, electrical appliances, construction, medical and health care, automobiles and household daily necessities. , play a variety of bonding role. [0003] In the preparation of silicone pressure-sensitive adhesives, there are mainly two main components: silicone-based glue and silicone resin as a tackifier, both of which can be cross-linked through condensation reactions. The performance of silicone PSAs depends on many factors, including base and resin composition, molecular weight, degr...
