Embodiment 1

[0058] A method for testing the bonding interface strength of rubber and composite materials, combining Figure 1-6 , including the following steps:

[0059] S1. Make test sample blocks, specifically including:

[0060] S01: Production of composite insulation products:

[0061] see figure 1 , the composite insulation product is a composite insulator 100, including a hollow insulating tube 110 and a silicone rubber shed 120 coated on the insulating tube, including the following specific steps:

[0062] S001. Prepare an insulating tube 110. The insulating tube 110 is formed by impregnating glass fiber yarn with epoxy resin glue solution through a winding and curing process. The curing agent is methyl tetrahydrophthalic anhydride curing agent.

[0063] S002. Uniformly coat a layer of vinyl tris(2-methoxyethoxy)silane coupling agent on the outside of the insulating tube 110 .

[0064] S003. Inject high-temperature vulcanized silicone rubber on the outer surface of the insulati...

Embodiment 2

[0077] This embodiment is basically the same as embodiment one, except that the rubber sample block width W2=10mm ± 0.5, all the other are the same as embodiment one, a test sample block-sample four is processed and tested and the test data is recorded as Table 2 shows.

[0078] Table 2 Test data records

[0079]

[0080] In this example, the width of the rubber sample block was changed for testing. Compared with the data in Table 1 in Example 1, the measured bonding strength σ under different sizes max The values ​​are still similar, which further illustrates the stability of the test method.

Embodiment 3

[0082] This embodiment is basically the same as embodiment two, the difference is that gamma-glycidoxypropyltrimethoxysilane coupling agent is used in this embodiment, and the rest are the same as embodiment two, and a test sample piece is processed - Sample five was tested and the test data was recorded as shown in Table 3.

[0083] Table 3 Test data records

[0084]

[0085] In this embodiment, the components of the coupling agent are changed, compared with the data in Table 2 in Example two, it can be known that the adhesive strength of the vinyl tris (2-methoxyethoxy) silane coupling agent is used It is greater than the bonding strength of γ-glycidoxypropyltrimethoxysilane. Through this test, the bonding strength of the interface between the rubber material and the composite material can be effectively characterized, and it is helpful to select a better bonding strength during the production process. Processes and materials to improve the interface bonding performance ...

Abstract

The invention discloses a test method for interface bonding strength between a rubber and a composite material. The method comprises the steps of preparing a test sample block, and the test sample block comprises a composite sample block, a rubber sample block bonded to the composite sample block and a bonding interface of the rubber and the composite material; the composite sample block is fixedby a testing machine, and a force is applied on the rubber sample block in the bonding interface direction; a maximum shear strength is obtained when the bonding interface is peeled off. By adopting the above test method, the strength of the bonding interface of the soft rubber material and the hard composite material during peeling can be simulated by actual tests under actual process production,and a true bonding effect is restored.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the interface bonding strength of rubber and composite materials. Background technique [0002] In the GB / T 19519 test of the national standard test about the end assembly and the interface test, there is no test that reflects the bonding strength of the interface between the rubber material and the composite material, and the test data cannot effectively reflect the peel strength and adhesion of the interface between the rubber material and the composite material. connection effect. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method for testing the interface bonding strength between rubber and composite materials, which can effectively characterize the bonding strength of the interface between rubber materials and composite materials through test data. [0004] In order to realize the a...
