Embodiment Construction

[0011] 1. When batching, first add aluminum powder and commercial silver powder into the epoxy resin and stir well, then add T31 curing agent and stir evenly before use.

[0012] 2 Adjust the glue according to this feeding procedure, the purpose is to prolong the use time. The use time in summer is about half an hour, and the use time in winter can be more than one hour. If the curing agent is added first, the epoxy resin will react with the curing agent, and then the aluminum powder and commercial silver powder are added, which shortens the use time of the adjusted magnetic conductive adhesive.

[0013] 3 The curing process can be adopted in two ways, and it will be completely cured after 24 hours at room temperature (25°C). If it is placed in an electric oven at 70-80°C for 1 hour, it can be completely cured.

Abstract

The invention discloses magnetic conducting glue for a turntable type test temperature sensor aluminum baffle plate, which is prepared by weighing epoxy resin, aluminum powder and commercial silver powder in a weight ratio, adding a proper amount of curing agent into the weighed materials and mixing the materials uniformly, has good effect and is low in cost.

Description

1. Technical field [0001] The invention relates to a chemical composition, in particular to a magnetically conductive glue for an aluminum baffle of a turntable-type test temperature sensor. 2. Background technology [0002] At present, the commonly used conductive adhesives in China can be used as magnetic conductive adhesives. For example, DAD-5 conductive adhesives have been widely used in China. Although they can meet the basic requirements of users, this product is realized by adding a large amount of silver powder to epoxy resin. Magnetic, expensive. 3. Contents of the invention [0003] The present invention aims at researching a new epoxy resin magnetic-conductive adhesive, aiming at the fact that the existing common epoxy adhesive does not have a magnetic-conductive effect, and the technical problem to be solved is to improve the magnetic-conductive epoxy resin after curing. [0004] The magnetic conductive adhesive for the aluminum baffle of the turntable test t...
