Abstract

The invention discloses a carbon battery sealing adhesive and a preparation method thereof, and belongs to the field of batteries. The carbon battery sealing adhesive comprises the following raw materials by weight: 50-70 parts of asphalt, 5-15 parts of lubricating oil, 5-10 parts of epoxy resin, 10-20 parts of solvent gasoline, 15-25 parts of asbestos powder, 1-5 parts of colloidal graphite powder, and 1-3 parts of tackifying resin. The carbon battery sealing adhesive prepared by taking asphalt with good cohesiveness, ageing resistance and low price as a main material and matching with lubricating oil, epoxy resin, solvent gasoline, asbestos powder, colloidal graphite powder and tackifying resin has the characteristics of a good sealing effect, good ageing resistance, no emergence at hightemperature, good adhesion at low temperature, no cracking, easy coating, little smell, lower cost, longer service life of a battery product and use convenience, and solves the problems of high cost,poor cohesiveness and easiness in aging of the sealing adhesive for the carbon battery in the prior art.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a carbon battery sealing glue and a preparation method thereof. Background technique [0002] The full name of the carbon battery is neutral zinc-manganese dioxide dry battery, which belongs to the primary battery in the chemical power source, and is a disposable battery. It is called a dry battery, which is relative to a battery with a flowable electrolyte. Carbon batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also for various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine. [0003] At present, there are mainly three kinds of zinc-manganese battery sealing adhesives: asphalt series, rubber series and epoxy series. The battery sealing adhesives of the asphalt series have good adhesion and anti-aging properties...
