Description

Fluororubber composition capable of being co-vulcanized and bonded with silicone rubber, rubber product and preparation method
Technical Field
The invention belongs to the technical field of rubber products, and particularly relates to a fluororubber composition capable of being co-vulcanized and bonded with silicone rubber, a rubber product and a preparation method.
Background
The solar photovoltaic technology is developed vigorously under the pressure of environmental protection, and an air bag consisting of an elastomer is required to be used when a solar photovoltaic module is produced. The existing solar photovoltaic air bag is made of a rubber product formed by bonding peroxide fluororubber and silicon rubber, but the existing peroxide fluororubber is peroxide-curable ternary fluororubber containing vulcanized monomers, has high specific gravity and high cost, and causes the cost of a solar photovoltaic module to increase along with the increase.
On the other hand, common bisphenol a fluororubbers and silicone rubber cannot be directly bonded, and although the conventional peroxide fluororubbers can be bonded with silicone rubber, the conventional peroxide fluororubbers are expensive, so that a new bonding technology is urgently needed to be developed.
In the prior art, in order to improve the current situation, Ningbo Fengmeng far east rubber Limited company adopts a bonding composition between fluorine rubber and silica gel, for example, a fluorine rubber and silica gel hot vulcanization bonding process disclosed in Chinese patent CN102786701A, the process adopts the bonding composition to be rolled into a sheet, the sheet is placed between inner layer fluorine rubber and silica gel to form a semi-finished product of inner layer fluorine rubber, bonding composition and silica gel structure, then heating and vulcanizing are carried out to bond and fix the inner layer fluorine rubber and the silica gel, the inner layer fluorine rubber is a vulcanizing agent consisting of 100 parts of fluorine rubber, 8-10 parts of active magnesium oxide, 5-6 parts of calcium hydroxide, 0.5-1 part of magnesium methacrylate, 8-10 parts of carbon black, 5-6 parts of calcium silicate, 1.2-1.5 parts of bisphenol AF, 2-3 parts of cross-linking agent and 2-2.5 parts of vulcanizing agent; the bonding composition is prepared from inner-layer fluorine glue, silica gel and fluorine coupling agent F-1 in a weight ratio of 3.8-4.2: 4.6-5.5: 1 are mixed. Although the document mentions that the inner layer fluorine glue and the silica gel of the fluorine glue silica gel product are firmly bonded, and the peel strength reaches more than 1.4kN/m, the inner layer fluorine glue and the silica gel are not directly bonded, but are bonded and fixed by a third layer (namely a bonding composition layer), so that the steps are multiple, the process is complex, the operation is complex, and the formulas of the inner layer fluorine glue and the bonding composition are very complex.
Later, some have improved the adhesion technology between fluororubber and silicone rubber, such as a composite oil-resistant rubber pipe with inner fluororubber and outer silicone rubber disclosed in chinese patent CN109931445A, which includes a core rod, an inner fluororubber layer, an intermediate silicone belt layer, an intermediate fluororubber layer and an outer silicone rubber compound layer, the inner fluororubber layer with added vulcanizing agent is wound on the core rod, the intermediate silicone belt layer with added vulcanizing agent and a certain distance is wound on the inner fluororubber layer, the intermediate fluororubber layer with added vulcanizing agent is continuously wound on the intermediate silicone belt layer, and the intermediate fluororubber layer and the intermediate silicone rubber layer are not completely overlapped, wherein the outer silicone rubber compound layer with added vulcanizing agent is wound on the intermediate fluororubber belt layer. The fluorine adhesive layer and the silica gel layer are bonded and fixed by respectively adding vulcanizing agents into the fluorine adhesive layer and the silica gel layer and then heating and vulcanizing the fluorine adhesive layer and the silica gel layer. Wherein, the vulcanizing agents of the fluorine rubber inner layer and the fluorine rubber belt intermediate layer are bisphenol A, bis-tetra-bis-penta vulcanizing agents. While the use of bisphenol a, bis-tetra-or bis-penta-bis-vulcanizing agents for the inner layer of fluorine rubber and the intermediate layer of fluorine rubber tape can achieve adhesion with the silica gel tape, the adhesion between the two is poor.
