Problems solved by technology

However, both of them use solvent toluene and acetone, which is not in line with the trend of environmental protection development.
[0008] In addition, even if the surface of copper-plated steel can be bonded to rubber with some of the above-mentioned adhesives and achieve satisfactory bonding strength, it is still difficult to have satisfactory adhesion to rubber if it is a surface of non-copper-plated steel. For example, in the tire industry, there is no copper plating on the truncated bead steel wire, and the bonding strength with rubber is weak. After a period of use, the steel wire will preferentially fall off from here, resulting in a decline in tire performance.

Embodiment 1

[0038]This example provides an environmentally friendly adhesive for adhering metal to rubber, prepared by the following reaction components in parts by weight: POLYVEST EP ST-E 100 100 parts, KH560 3 parts, HG-0111 0.25 parts and POLYVEST110 0 parts. The metal reinforcement layer takes the bead wire commonly used in the tire industry as an example, and the rubber takes natural rubber compound as an example.

[0039] POLYVEST EP ST-E 100 is a commercially available product from Evonik Industries and is a triethoxysilane terminated polybutadiene. KH560 is a product available from Qufu Chenguang Chemical Co., Ltd., and is γ-(2,3-glycidoxy)propyltrimethoxysilane. Catalyst HG-0111 is a product commercially available from Hangzhou Sibao Chemical Co., Ltd., and is dibutyltin dilaurate. Diluent POLYVEST 110 is also available from Evonik Industries and is a non-functionalized liquid polybutadiene.

[0040] The steel wire used in the experiment is the Φ1.55mm uncoated tempered bead ...

Abstract

The invention relates to an environmental-friendly adhesive for adhering a metal onto rubber and the application of the environmental-friendly adhesive. The environmental-friendly adhesive comprises the following components in parts by weight: 100 parts of alkoxy silicon ended polybutadiene, 1-5 parts of a silane coupling agent, 0.1-0.5 part of a catalyst and 0-400 parts of a diluent. Compared with the prior art, the environmental-friendly adhesive provided by the invention is free of solvents and is environmental-friendly, in addition, effectively bonding of a metal reinforced part with a rubber substrate can be promoted in a reaction cross-linking mode.

Description

technical field [0001] The present invention relates to an adhesive, in particular to an environmentally friendly adhesive for adhering metal to rubber. Background technique [0002] Since metal / rubber composites are subjected to extremely high stresses during tire rolling, in particular to repeated actions of compression, bending or changes in curvature, these composites must, in a known manner, meet a large number of sometimes conflicting technical criteria, such as homogeneity flexibility, resistance to bending or compression, tensile strength, abrasion and corrosion resistance and must maintain these properties at extremely high levels for as long as possible. [0003] The adhesion between the rubber and the reinforcement plays a major role in the durability of the above properties. A conventional method of joining rubber compositions to carbon steel consists in coating the surface of the steel with brass (copper / zinc alloy), providing an interface between the steel and...
