Abstract

The invention relates to the technical field of adhesives, in particular to an adhesive composition for electronic cloth edge sealing and a preparation method thereof. The adhesive composition is prepared from the following components in parts by weight: 80-90 parts of waterborne polyurethane, 5-7 parts of epoxy resin, 0.05-0.3 parts of a wetting agent and 3-15 parts of water, and has the advantages of high adhesive force and strong permeability.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive composition used for edge sealing of electronic cloths and a preparation method thereof. Background technique [0002] Electronic cloth refers to the general term of electronic grade glass fiber cloth used in the electronics industry. It is a high-grade product in electronic grade glass fiber cloth. The main specifications are 7637, 7630, 7628, 7615, 1506, 2116, 2113, 3313, 1080, 106, 104, which are mainly used in the manufacture of copper clad laminates. [0003] At present, most of the electronic grade glass fiber cloths sold in the market are feather edge electronic cloth, that is, in order to prevent the cloth edge from falling off, the electronic grade glass fiber cloth clamps the weft yarn by the leno twisting method through the weaving mechanism of the loom during the weaving process. Make sure that the glass yarn on the side of the electronic cloth does no...
