Problems solved by technology

However, the sealants currently used are often damaged due to excessively high temperatures, cracking and flowing at high temperatures affect the sealing performance of the vacuum bag, and the burden of mold cleaning is increased due to the large amount of residual glue during demoulding.

Abstract

The invention discloses a basalt nano high-temperature sealant which comprises the following components: a matrix resin, a telechelic polymer, basalt powder, a vulcanizing agent and a cross-linking agent; and the basalt nano high-temperature sealant comprises the following components in parts by weight: 21-30 parts of the matrix resin; 35 to 45 parts of the telechelic polymer, 40 to 60 parts of basalt powder, 5 to 10 parts of the vulcanizing agent, and 2 to 7 parts of the cross-linking agent. According to the technical scheme, the telechelic polymer is added into the sealant, so that the telechelic polymer can be crosslinked into a net structure under the conditions of the vulcanizing agent and heating, the problem that the sealant becomes thin and sticks to a mold at high temperature is solved, and the structural strength of the sealant and the form stability of the sealant in a high-temperature environment can be greatly improved by taking basalt powder as a filler.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a basalt nano high-temperature sealant. Background technique [0002] The vacuum forming process needs to seal the product between the mold and the vacuum bag, and pressurize the product by vacuuming to make the product denser and have better mechanical properties. In the process of implementing the vacuum bag compression molding method, it is necessary to use a vacuum bag to seal the vacuum, that is, between the vacuum bag and the production mold and between the vacuum bag and the vacuum bag need to be sealed, because there will be a heating process during use , so that the molding device is in a high temperature state, at this time, the adhesive tape used for sealing is required to have a certain high temperature resistance; at the same time, in order to facilitate industrial operation, it is required that the sealing colloid will not remain on the mold during demoulding. However, the ...
