Embodiment

[0025] A nano-rare earth silicone sealant, which is characterized in that: the weight ratio is as follows:

[0026] Room temperature vulcanized silicone rubber 20-90 parts,

[0027] 10-80 parts of nano-active substances,

[0028] Rare earth element 0.001-0.01 part,

[0029] Coloring agent 1-10 parts,

[0030] White carbon black 5-20 parts,

[0031] Curing agent 1-5 parts,

[0032] 1-5 parts of coupling agent;

[0033] The nano active material is soft calcium carbonate of nano scale.

Abstract

A nano-rare-earth silicones sealant is obtained by adding rare-earth, nano active materials into normal silicones sealant. It is of resistance to high or low temperature, oil, water, and varied weather. The domain of the temperature is -6deg.C -300deg.C , and pressure reaches 10MPa. It can be used for electronic components, household appliances, electric heating poles and so on.

Description

1. Technical field: [0001] The invention belongs to the field of sealant preparation, and in particular relates to a nanometer rare earth silicone sealant. 2. Background technology: [0002] There are many kinds of sealants of similar products sold in the market now, although they can all play a sealing role, they cannot achieve a high sealing effect, such as high temperature resistance and low temperature. There are certain defects, which cannot achieve a high sealing effect Require. 3. Contents of the invention: [0003] The object of the present invention is to add rare earth elements and nano-active substances on the basis of the original room temperature vulcanized silicone sealant to achieve a nano-rare earth silicone sealant resistant to high and low temperatures, so as to overcome the above-mentioned shortcomings. [0004] The purpose of the present invention is achieved by the following technical solutions: [0005] A nano-rare earth silicone sealant, which is c...
