Abstract
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
The present invention relates to field tests, is the method for testing of a kind of all-steel cord and sizing material bounding force in detail.
Background technology
As everyone knows, the various glue components of tire just have certain bounding force after sulfuration, and tire is affect one of tyre life by the bounding force size of various all-steel cord and sizing material, how authentic testing goes out the bounding force both it, is one of difficult problem of running into of many enterprises.At present, the method for testing that can test out the bounding force of all-steel cord and sizing material truly is not also had.
Summary of the invention
In order to overcome the deficiency of the binding power test of existing tested steel silk cord and sizing material, the invention provides the method for testing that a kind of comparable serious field test goes out the bounding force of all-steel cord and sizing material.
The technical solution adopted for the present invention to solve the technical problems is: the method for testing of a kind of all-steel cord and sizing material bounding force, it is characterized in that, first sulfurizing mould is made, sulfurizing mould is by upper press cover, sealing gasket, lower cover forms, upper press cover is that the thick solid cast steel for 300mm*200mm*5mm of length and width is dull and stereotyped, lower cover is the thick hollow cast steel plates for 300mm*200mm*15mm of length and width, airtight on the downside of lower cover, it is uncovered dead slot on the upside of lower cover, the specification of dead slot is 280mm*180mm*10mm, described dead slot has a pipeline to communicate with the external world, a high temperature resistant not easily deformable seal pad is had to be used for seal compression air between upper press cover and lower cover, cut sample, described sample is carcass cord cord or the belt wirecord fabric of workshop calendering, be placed on by lower cover in vulcanizing press, sealing gasket is placed on lower cover, and sample is placed on sealing gasket, and upper press cover is placed on sample, open pressurized air valve again after vulcanizing press matched moulds puts in place, pressurized air enters in dead slot by pipeline, is pressurizeed to sample by sealing gasket, after vulcanizing press matched moulds puts in place, sulfuration is carried out to sample, after sulfuration terminates, closes compression air door, open vulcanizer and take out sample, after sample parks 24 hours under standard atmosphere, from sample, cut three all-steel cords, the middle 17.5mm that retains is not separated, and all the other parts will be separated, electronic tensile machine carries out the extension test of sample, upper fixture clamps an all-steel cord in the middle of sample upper end, and lower clamp clamps other two all-steel cords in sample lower end, and draw speed is 100mm/min, stretch until all-steel cord is separated, read adhesion values.
The invention has the beneficial effects as follows, simple to operate, can real simulation tire at pan vulcanization, comparable serious field test goes out the bounding force size of all-steel cord and sizing material.
Accompanying drawing explanation
