Abstract
The technical problem to be solved is to provide the production technology of a kind of neutral transparent silicone sealant, comprises the steps: the first step, glue in cylinder, second step, static wadding stream mixing, the 3rd step, subpackage；In the first step cylinder of the present invention during glue, 107 silicone rubber in glue cylinder are the slowest with the reaction of cross-linking agent methyl tributanoximo silane, granule skinning will not be produced before glue cylinder being moved to static machine and affect product appearance, it is possible to be effectively improved product appearance quality；Through the wadding stream mixing of second step static state machine and the 3rd step subpackage, process is vacuum pipe static mixing, will not ingress of air, therefore, it is possible to during being greatly reduced glue produce bubble, it is effectively improved the presentation quality of fluid sealant finished product, reduces the replacing number of times of drainage screen simultaneously；Production technology is smooth rationally, effectively reduces hand labor intensity, improves the production efficiency of subpackage efficiency and whole production line.
Description
Technical field
The present invention relates to the production technology of a kind of silicone sealant, specifically refer to the production technology of a kind of neutral transparent silicone sealant.
Background technology
At present, the production technology of domestic neutral transparent silicone sealant is first to complete glue in glue cylinder, and glue cylinder is being moved to carry out on racking machine the subpackage of fluid sealant.The major defect of the method is: the fluid sealant presentation quality that subpackage goes out is relatively poor, needs constantly to change drainage screen to improve the presentation quality of fluid sealant during subpackage.And change drainage screen and cause fluid sealant ingress of air, thus produce aeration product appearance.And, in existing production technology, artificial mechanical's labor intensity is big, and intricate operation, increase labour cost, production efficiency is low.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide the production technology of a kind of neutral transparent silicone sealant, production efficiency can be effectively improved, labor intensity is little, reduces the number of times changing drainage screen, is effectively improved product appearance quality.
For solving above-mentioned technical problem, the technical solution used in the present invention is, the production technology of a kind of neutral transparent silicone sealant, comprises the steps:
The first step, glue in cylinder:
In glue cylinder, according to quality proportioning, add 45-50 part 107 silicone rubber, 4-6 part cross-linking agent methyl tributanoximo silane, and 20-30 part 3# alkane oil, be evacuated to-0.09mpa, stir 20min；Add 12-18 part gas-phase silica, stir；
Second step, static wadding stream mixing:
Glue cylinder being moved on static machine, according to quality proportioning, adds 3-8 part cross-linking agent vinyl tributyl ketoximyl silane, 2-4 part coupling agent KH550, KH560,0.1-0.3 part catalyst dibutyltin dilaurylate, through static machine wadding stream mixing；
3rd step, subpackage:
Through vacuum sealing tube road static mixing, it is packed as finished product with filter screen.
The production technology of above-mentioned a kind of neutral transparent silicone sealant, comprises the steps:
The first step, glue in cylinder:
In glue cylinder, according to quality proportioning, add 46.8 part of 107 silicone rubber, 5 parts of cross-linking agent methyl tributanoximo silanes, and 25 parts of 3# alkane oils, be evacuated to-0.09mpa, stir 20min；Add 15 parts of gas-phase silicas, stir；
Second step, static wadding stream mixing:
Glue cylinder being moved on static machine, according to quality proportioning, adds 5 parts of cross-linking agent vinyl tributyl ketoximyl silanes, 3 parts of coupling agents KH550, KH560,0.2 part of catalyst dibutyltin dilaurylate, through static machine wadding stream mixing；
3rd step, subpackage:
Through vacuum sealing tube road static mixing, it is packed as finished product with filter screen.
The invention have the advantages that and Advantageous Effects:
1, in the first step cylinder of the present invention during glue, 107 silicone rubber in glue cylinder are the slowest with the reaction of cross-linking agent methyl tributanoximo silane, granule skinning will not be produced before glue cylinder being moved to static machine and affect product appearance, it is possible to be effectively improved product appearance quality.
2, the present invention is through the wadding stream mixing of second step static state machine and the 3rd step subpackage, process is vacuum pipe static mixing, will not ingress of air, therefore, it is possible to during being greatly reduced glue produce bubble, it is effectively improved the presentation quality of fluid sealant finished product, reduces the replacing number of times of drainage screen simultaneously.
3, the production technology of the present invention is smooth rationally, effectively reduces hand labor intensity, improves the production efficiency of subpackage efficiency and whole production line.
