Conductive adhesive

Abstract

The invention relates to a conductive adhesive. The conductive adhesive is characterized by being prepared from raw material components in parts by weight as follows: 1-24 parts of acrylic rubber, 2-14 parts of an emulsifier, 5-21 parts of triethanolamine, 3-19 parts of diatomite, 2-19 parts of talc, 3-30 parts of acetone, 7-19 parts of sodium bisulfite, 8-10 parts of hydroxypropyl methylcellulose, 11-20 parts of conductive powder, 9-13 parts of polyethylene glycol, 3-7 parts of a dispersant, 6-12 parts of a binder, 8-12 parts of a coupling agent, 6-10 parts of triphenyl phosphate, 9-11 partsof ethyl alpha-cyanoacrylate, 6-8 parts of 4,4'-diphenylmethane diisocyanate and 3-5 parts of water. The provided conductive adhesive has good electrical conductivity, excellent flame retardant effect, excellent flexing resistance and high temperature resistance, and can be used in various environments.

Description

technical field [0001] The invention relates to the field of glue, in particular to a conductive glue. Background technique [0002] In electronic systems, with the substantial increase in chip processing speed, electromagnetic compatibility issues such as electromagnetic radiation are becoming more and more serious. Materials such as conductive rubber and conductive foam are widely used in casings and circuits for electromagnetic shielding. In order to avoid changes in the position of the shielding material caused by factors such as vibration, thereby reducing the shielding performance, conductive tape has become a convenient choice for operation. [0003] There are a lot of polymers in electronic products that can easily cause sparks or spread flames. When heated, they will decompose into unstable flammable objects, which are easy to cause fires. In the field of electronics, for the manufacture of electronic products widely used in daily life, the requirement of fire pro...
