Foreword

This standard was drafted in accordance with the rules given in GB/T 1:1-2009: This standard was proposed by the China Petroleum and Chemical Industry Federation: This standard is organized by the National Rubber and Rubber Products Standardization Technical Committee Dipping Framework Material Sub-Technical Committee (SAC/TC35/SC13) Focus: Drafting organizations of this standard: Shenma Industrial Co:, Ltd:, Qingdao Tianbang Thread Industry Co:, Ltd:, Pingdingshan Shenma Cord Fabric Development Co:, Ltd: Company, Qingdao University of Science and Technology, Jinhua Yalun Chemical Fiber Co:, Ltd:, Qingdao New Material Technology Industrial Park Development Co:, Ltd:, Qingdao University of Science and Technology New Rubber and Plastic Technology Technology Service Co:, Ltd:, Qingdao Shengke Material Co:, Ltd: The main drafters of this standard: Duan Wenliang, Yu Dejiang, Li Xin, Liu Li, Xiang Jun, Zhang Huiyun, He Zehan, Hao Xiao, Li Xiaohui, Wang Anle, Wang Jie, Qiao Sihuai, Zhai Songtao, Ying Kejun, Lu Xiaodong, Chen Yimin: Test method for dynamic bonding performance of dipped cord and cord

1 Scope

This standard specifies the test methods for the dynamic adhesion of dipped cords, cords and rubber: This standard is applicable to the evaluation of the dynamic adhesion performance of dipped cords and cords for rubber products: Dipped yarn and rubber for rubber products The dynamic adhesive performance evaluation of the glue can also refer to implementation:

2 Normative references

The following documents are indispensable for the application of this document: For dated reference documents, only the dated version applies to this article Pieces: For undated references, the latest version (including all amendments) applies to this document: GB/T 2941 Rubber Physical Test Method General Procedure for Sample Preparation and Adjustment GB/T 8170 Numerical rounding rules and the expression and determination of limit values GB/T 31333 Test method for bonding strength of dipped cord GB/T 32110 Terms and definitions of dipped framework materials

3 Terms and definitions

The following terms and definitions defined in GB/T 32110 apply to this document: 3:1 Adhesion retention rate After the dynamic test, the arithmetic average of the adhesion of all samples, and the arithmetic average of the adhesion of all the samples without the dynamic test Ratio: Note: Expressed in percentage (%): 3:2 Falingoffnumberoftimes During the dynamic adhesion test, when the sample falls off after reciprocating shearing motion, the arithmetic average of the number of reciprocating motions of all samples:

4 Principle

The dipped cord or dipped cord and rubber are vulcanized to prepare a sample, as shown in Figure 1: First connect the two ends of the sample with two different quality The load weight is firmly connected, and the sample to be tested is straightened by the weight and fixed on the test device with heating function; during the test, it is at a certain temperature Next, through the swing mechanism, the rubber block in the sample is moved along the direction of extension of the sample with a certain amplitude and frequency relative to the cord or cord in the sample: The reciprocating shearing motion produces continuous dynamic shear between the cord or cord and the rubber interface: As the test continues, the cord or cord and the rubber The adhesive force of the glue interface will gradually decrease, and the test will stop when the test is reached; or continue the test until the rubber block and the dipping cord or cord are separated drop: Take the sample's adhesion retention rate after a certain time test under the set reciprocating shear motion frequency, temperature and swing amplitude or sample The number of reciprocating shear motions under the set reciprocating shear motion frequency, temperature and swing amplitude until the sample breaks off The dynamic bonding performance of dipped cord or cord and rubber at low temperature: ......
