Embodiment Construction
[0010] Such as figure 1 , figure 2 As shown, first make a vulcanization mold. The vulcanization mold is composed of an upper gland 1, a gasket 3, and a lower gland 4. The upper gland 1 is a solid cast steel plate with a length, width, and thickness of 300mm*200mm*5mm, and the lower gland 4 It is a hollow cast steel plate with a length, width, and thickness of 300mm*200mm*15mm. The lower side of the lower gland 4 is airtight, and the upper side of the lower gland 4 is an open empty slot. The specification of the empty slot is 280mm*180mm*10mm. The empty groove has a pipeline 5 communicating with the outside world, and there is a high-temperature-resistant and non-deformable gasket 3 between the upper gland 1 and the lower gland 4 to seal the compressed air; cut out a sample 2 with a length of 100mm and a width of 50mm, and the The above sample 2 is carcass steel cord or belt layer steel cord rolled in the workshop; the lower gland 4 is placed in the flat vulcanizer, the seali...

The invention discloses a test method for adhesive force between a steel cord and a rubber material, and belongs to the field of test apparatuses of tyre performances. A sample is tyre-body steel cord fabric calendered in a workshop or belt steel cord fabric. A lower press cover is put in a press vulcanizer, a sealing gasket is put on the lower press cover, the sample is put on the sealing gasket, and an upper press cover is put on the sample. After the press vulcanizer is at a complete die-assembling state, a compressed-air valve is opened, and compressed air enters an empty tank through a pipe, and the sample is pressurized through the sealing gasket. After the press vulcanizer is at the complete die-assembling state, the sample is sulfurized, and after sulfurization is finished, the compressed-air valve is closed, the sample is taken out from the press vulcanizer, the sample is stayed at standard humidity and temperature for 24 h, then three steel cords are cut from the sample, the middle part with the width of 17.5 mm is not separated, and the other parts are separated. The sample stretching test is performed on an electronic tensile-testing machine, an upper clamp clamps a wire cord at the middle of the upper end of the sample, a lower clamp clamps the other two wire cords at the lower end of the sample, the stretching speed is 100 mm / min, stretching is performed until the steel cords are separated, and the bonding force value is read.
Description
technical field [0001] The invention relates to the field of testing, in particular to a testing method for the adhesion between steel cords and rubber materials. Background technique [0002] As we all know, the various rubber parts of the tire have a certain adhesive force after vulcanization, and the adhesive force between the various steel cords used in the tire and the rubber material is one of the factors that affect the life of the tire. How to truly test the relationship between the two Adhesion is one of the problems encountered by many enterprises. At present, there is no test method that can truly test the adhesion between the steel cord and the rubber compound. Contents of the invention [0003] In order to overcome the deficiencies of the existing tests for testing the adhesion between steel cords and rubber materials, the present invention provides a test method that can more realistically test the adhesion between steel wire cords and rubber materials. ...
