Butyl tape is prone to break when heated, what is the situation? How to solve this situation? Sometimes this is the case. The butyl tape is not heated smoothly during use. This is mainly due to the inappropriate temperature control when the butyl tape is extruded, which will affect the rheological condition. Yes, it affects the quality and beauty of the product, so if this situation occurs, how to correctly solve this problem?
A key issue of the whole is temperature. It is only necessary to control the temperature properly, which will directly affect the rheological state during processing, and also affect the appearance and quality of the product. The temperature cannot be too high or Too low, if it is too high, it will cause the sealant to melt too much, which is not easy to form, and it has always been flowing. If the temperature is too low, it will still reduce the fluidity of the glue. No glue, affect the progress of construction. This will also result in unsmooth extrusion, and there will be bubbles in the waterproof adhesive of the butyl tape during processing, which will cause the situation of glue breakage during the extrusion process.
The research results show that the retention rate of resin vulcanization performance of butyl rubber after 160 degrees Celsius * 24h is higher than that of sulfur-cured donor vulcanized IIR, the resin dosage is 5-10 parts, and IIR vulcanizate has a relatively high mechanical retention rate Yes, different resins have different effects on the aging resistance of IIR. When the amount of zinc oxide in the compound reaches 5 parts, the aging resistance of the vulcanized rubber is relatively good. We introduced the physical machinery of different resins vulcanized butyl rubber Performance, physical and mechanical properties of tertiary butyl phenol resin vulcanized butyl rubber with different softening points, to study the surface, in order to obtain a good vulcanization effect, the resin should contain a certain amount of methylol and ether bond structure, the resin must be oil-soluble Yes, vulcanization will not occur when the methylol content is less than 3%.
