Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since the silicone sealant is a polymer material, which is exposed outside, it is easy to be eroded by ozone and ages. The sealing effect becomes worse, so that the sealing effect is not long-lasting, so there is still room for improvement

Abstract

The invention relates to the technical field of sealants, and in particular, relates to a silicone weather-proof sealant which comprises the following components in parts by mass: 45 parts of room-temperature vulcanized silicone rubber, 40 to 50 parts of nano calcium carbonate, 4 to 6 parts of methyl tributylketoxime silane, 0.5 to 1 part of vinyl tributylketoxime silane, and 0.03-0.05 part of a catalyst. The silicone weather-proof sealant has the effects of being not prone to aging, long in service life and lasting and stable in sealing effect.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a silicone weather-resistant sealant. Background technique [0002] At present, as people's requirements for the quality of life are getting higher and higher, people are paying more and more attention to the sealing performance of houses, especially the gap between the glass plate of the glass window and the window frame. Water seepage, ventilation and other conditions seriously affect people's living experience. [0003] In the existing window sealing, silicone sealant is usually used to fill the gap between the glass plate and the window frame, so as to achieve a better sealing effect. [0004] The above-mentioned existing technical solutions have the following defects: because the silicone sealant is a polymer material, it is exposed outside, and it is easy to be eroded by ozone to cause aging. The sealing ability of the aged silicone sealant is greatly reduced, resulting i...
