Abstract
The invention belongs to the field of polymer material processing, and particularly relates to a method for preparing a rubber-based adhesive for a communication product. The method specifically comprises the following steps of: firstly, preparing a gross rubber from a matrix rubber by using a roll mill; secondly, uniformly kneading a tackifier, a plasticizer and a filling material by using a kneading machine or an internal mixer; and finally, extruding the mixture by using a rubber extruder to prepare a pressure-sensitive adhesive with a specific shape. The rubber-based adhesive is suitable for waterproof insulated sealing of joints and terminals of various indoor and outdoor communication products, and the product performance of the rubber-based adhesive is excellent, so the rubber-based adhesive has an extensive market space.
Description
Technical field
The invention belongs to the Process Technology of Polymer technical field, be specifically related to a kind of preparation method who is used for the rubber-based adhesive of communication product.
Background technology
Along with steadily improving of China's national life level, domestic communication enterprise is also along with its people's demand emerge in multitude like the mushrooms after rain, Communication Equipment self-contained, reprocess, in the maintenance process, it is particularly important that the waterproof insulation of joint seems, though domestic have to a certain degree R and D for this series products, but than external matured product, still there is bigger gap on the performance, simultaneously because external technology and raw material monopolization, make that the price of this series products is high at home, restriction to a certain degree and influenced the development of domestic communication enterprise.
Polyisobutene is a kind of typical saturated straight chain alkane, because its specific molecule structure, make it in waterproof, have special advantage on insulation and the performance such as ageing-resistant, polyisobutene can be re-dubbed the sizing agent that is used for special purpose with tackifying resin, low-molecular-weight polyisobutylene, mineral wet goods material simultaneously.Isoprene-isobutylene rubber is the multipolymer of the isoprene of iso-butylene and 1%-3%, because it has similar molecular structure to polyisobutene, have outside the above-mentioned excellent properties of polyisobutene, also can be by mode such as crosslinked, strengthen its intensity, obtain excellent more performance.The pure polyisobutene Tg=-65 of the second-order transition temperature Tg of polyisobutene ℃～-30 ℃, make it under lower temperature, all have elastomeric property, because this material has biocompatibility, nontoxic performance, all obtained in fields such as food-processing and medical adhesives paying close attention to widely simultaneously.But,, make it all well do not developed at home in this technology owing to domestic raw material production and Technology are not overripened a few years ago.
In recent years, the rapid progress that obtains along with China's chemical industry, domestic present stage also can be synthesized a part originally can't the synthetic raw material, what deserves to be mentioned is the isoprene-isobutylene rubber that Yanshan Petrochemical is produced here, for domestic-developed with produce such sizing agent and created extremely beneficial condition.Simultaneously, along with domestic research and development and production strength for rubber-based adhesive improves, develop this kind sizing agent and also clear away significantly at the obstacle of technical elements.Because its vast market space, domestic a lot of enterprises still still have bigger gap at aspect of performance and international product also in the research and development of doing in this respect, can not well satisfy the requirement on using.
