Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below.

[0022] The rubber-metal bonding quality detection method is characterized in that comprising the following steps:

[0023] The first step: configure the bath solution with metal cations and anions,

[0024] The second step: immerse the rubber and metal parts in the bath for a specified period of time according to the method of metal electroplating, so that the cations and anions in the bath will be polarized under the action of the current, squeezed into the rubber-metal bonding interface, and the adhesive Destroying the stability of the chemical bond with the metal bond;

[0025] Step 3: Take out the rubber and metal parts to check the peeling and damage of the rubber and metal bonding edge, and judge whether the bonding quality of the rubber and metal parts is qualified according to the bonding quality requirements of the product.

[0026] 2. The method for detecting the quality of rubber-...

Abstract

The invention discloses a rubber-metal bonding quality detection method. The method is characterized by comprising the following steps: 1, preparing a bath solution with metal cations and anions, 2, soaking a rubber-metal part into the bath solution, polarizing the cations and anions in the bath solution under the action of current according to a metal electroplating method within specified time,extruding the cations and anions into a rubber-metal bonding interface to destroy the stability of adhesive and metal bonding chemical bonds; and 3, taking out the rubber-metal part, checking the stripping damage condition of the bonding edges of rubber and metal, and judging whether the bonding quality of the rubber-metal part is qualified or not according to the bonding quality requirement of the product. Nondestructive testing of the rubber-metal bonding quality is achieved, product scrapping after detection is avoided, and the method is suitable for batch detection of rubber metal parts. The invention further provides a rubber-metal bonding strength quality judgment method.

Description

technical field [0001] The invention relates to a rubber-metal bonding quality detection method and a bonding strength quality judging method, which are used for non-destructive testing of rubber-metal bonding quality and rapid judgment of rubber-metal bonding strength quality. Background technique [0002] Rubber products are more and more widely used in locomotives, automobiles, oil exploration and other fields. Rubber has certain tensile, wear-resistant and tear-resistant properties, and it must also maintain good elasticity for a long time under low temperature conditions. , with the rapid development of high-speed rail transit, its demand for rubber is increasing. At the same time, the performance requirements of rubber are becoming more and more stringent, especially for the bonding performance of metal rubber products. Higher requirements. The rubber mat formed by metal and rubber vulcanization is widely used in the vibration damping system of rail transit. In the pr...
