Abstract

The invention discloses a thermal activating glue film. The thermal activating glue film is characterized by consisting of resin, rubbers, fillings, a cross linker, a perduren compound and a promoter which are melted and mixed by a mixing mill and then calendered into a film. The thermal activation glue film is a thermal activating glue film which has the advantages of fast solidifying speed, excellent storage stability and high solidifying intensity, temperature resistance, environment protection and low cost.

Description

Technical field: [0001] The invention relates to the technical field of adhesive films, in particular to a thermally activated adhesive film and a preparation method thereof, in particular to a thermally activated adhesive film with fast curing speed, temperature resistance and stable storage under hot pressing. Background technique: [0002] The adhesive film is usually non-tacky at room temperature, but it melts or cross-links and solidifies under heat and pressure to bond the adherend. There are many types of existing adhesive films according to different raw materials and uses, some have a long curing time, some have poor storage stability, some have glue overflow after curing, some have high cost, and as we all know, there are many adhesive films at present. It is a solvent method process, that is, all substances are first dissolved in a solvent, mixed evenly and then coated, and the required film is formed after the solvent volatilizes. This process is relatively compl...
