Problems solved by technology

[0003] However, the interlayer metal of the traditional rubber sheet material is often achieved through the bonding of adhesives. The degree of adhesion of the adhesive determines the quality and service life of the rubber sheet material. The existing technology is rubber layer and metal interlayer The adhesion is not enough, and the material of each layer is detached due to external factors (temperature, humidity, oil, etc.) during use

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 -- As described in 4, a closed-pore rubber material includes a metal plate layer 1, each of the two sides of the metal plate layer 1 is coated with a treatment agent layer 2, and the two layers of the treatment agent layer 2 are respectively coated with a bottom Coating 3, rubber layers 4 are respectively coated on the two layers of the undercoating 3 .

[0026] The surface of the metal plate layer 1 is provided with a roughened structure. In this embodiment, the roughened structure refers to the burrs or protrusions on the surface of the metal plate, and the burrs are arranged on the metal plate layer 1, which increases the contact area between the metal plate layer 1 and the rubber layer 4, and improves the Adhesion, which makes the firmness of the rubber material.

[0027] The thickness of the metal plate 1 is bet...

Abstract

A closed pore rubber material comprises a metal plate layer, the two faces of the metal plate layer are each coated with a treating agent layer, the two treating agent layers are each coated with a bottom coating, and the two bottom coatings are each coated with a rubber layer. Compared with the prior art, the beneficial effects are that: a metal layer with burrs is arranged in the rubber material, so that the contact area of the metal layer and the rubber layer is increased, the adhesion strength of the two layers is improved, the possibility that the materials of all the layers are separateddue to the use environment (temperature, humidity, greasy dirt and the like) is reduced, and the rubber material is firmer, more oil-resistant and more heat-resistant.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a closed-pore rubber material. Background technique [0002] The rubber sheet is a flake product with a certain thickness and a large area made of rubber as the main material through vulcanization. The rubber sheet has high hardness and can work in the air at a temperature of -40 ° C to 140 ° C. The rubber sheet is made of mixed rubber by calendering or extrusion, vulcanized by a flat vulcanizing machine or continuously vulcanized by a drum vulcanizing machine. It is widely used in industrial and mining enterprises, transportation departments, and housing floors. Used as sealing rubber rings, rubber pads, door and window seals, and laying workbenches and floors; metal skeletons are sandwiched in the rubber sheets to enhance the hardness of the rubber sheets. [0003] However, the interlayer metal of the traditional rubber sheet material is often achieved through the bonding of ad...
