The compounding method of fluororubber, nitrile rubber and butyl rubber provided by the present invention will be described in detail with reference to the following examples, but they should not be construed as limiting the scope of the present invention.
Example 1
1) Plasticating: and respectively feeding raw fluororubber, raw nitrile rubber and raw butyl rubber into an open mill, and setting the temperature to be 40 ℃, wherein the raw butyl rubber and the raw fluororubber need to be plasticated for 3 minutes, and the raw nitrile rubber needs to be plasticated for 10 minutes, so as to obtain plasticated fluororubber, plasticated nitrile rubber and plasticated butyl rubber.
2) Mixing: the plasticated fluororubber, the plasticated nitrile rubber and the plasticated butyl rubber are mixed according to the formula shown in the table 1, and various auxiliaries are added to enable the mixed rubber to meet the performance requirements.
Table 1 example 1 rubber compound formulation
3) Pre-vulcanization and vulcanization: the compounded fluororubber, the compounded nitrile rubber and the compounded butyl rubber were each presulfurized in a vulcanizer using a mold of 14cm × 12cm with a thickness of 1mm at a temperature of 140 ℃, for 10 minutes for the compounded butyl rubber, for 5 minutes for the compounded nitrile rubber and for 20 minutes for the compounded fluororubber. Then cooling the mixture to room temperature, combining the mixture according to the sequence of fluororubber-nitrile rubber-butyl rubber, and finally putting the mixture into a mould with the thickness of 2mm and the thickness of 14cm multiplied by 12cm for vulcanizing 15 minutes at 160 ℃ to obtain a finished product of the compound rubber.
The adhesive-to-adhesive bond strengths obtained using the formulation of example 1 are shown in table 2. The method according to which the adhesive strength is tested is GB/T532-2008.
Table 2 adhesion strength between rubbers of example 1
| Fluororubber and nitrile rubber | Nitrile rubber and butyl rubber | |
| Adhesive strength kN/m between sizing materials | ＞0.99 | ＞0.5 |
Since the prepared film having higher adhesive strength could not be peeled off for testing adhesive strength. Therefore, only three-layer structures with poor composite condition can be selected for testing. The adhesion strength of the other samples is greater than the data in table 2, so the adhesion strength in table 2 gives the lower limit.
Comparative example 1
The only difference from example 1 is that the mix formulation is shown in table 3.
TABLE 3 formulation of comparative example 1 rubber compound
The adhesive-to-adhesive bond strengths obtained using the formulation of comparative example 1 are shown in table 4.
TABLE 4 adhesive strength between rubbers of comparative example 1
| Fluororubber and nitrile rubber | Nitrile rubber and butyl rubber | |
| Adhesive strength kN/m between sizing materials | 0 | ＞0.3 |
As can be seen from the above examples and comparative examples, the present invention enhances the adhesive strength between nitrile rubber and fluororubber by adding tetrabutyl benzotriazole salt to the compounded nitrile rubber as an intermediate layer, thereby enabling the nitrile rubber and the fluororubber to be bonded together during vulcanization.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
