Problems solved by technology

[0003] That is, the Mooney viscosity of the processed compounded compound is high and the dispersion of silica is poor.
Due to the rapid heat generation of the rubber material, a multi-stage master batching process is required, which affects the full play of the performance of the belt layer adhesive rubber material, increases the cost of rubber material production and processing, and the adhesion of the belt layer steel cord. Poor performance

Embodiment 1

[0022] Embodiment 1 provides a kind of adhesive glue for steel cord of belt layer, its component formula is by the ratio of mass parts:

[0023] 100 parts of natural rubber, 43 parts of carbon black, 15 parts of white carbon black, 8 parts of zinc oxide,

[0024] 1.2 parts of cobalt decanoate, 2.5 parts of anti-aging agent, 1.5 parts of resorcinol,

[0025] 5 parts of insoluble sulfur, 5 parts of adhesion promoter, 1.2 parts of sulfenamide accelerator, and 1.5 parts of 3-octanoylthio-1-propyltriethoxysilane newly added in the component formula.

[0026] The added 3-octanoylthio-1-propyl triethoxysilane is used as a coupling agent, which will not be as represented by tetrasulfide silane coupling agents such as SI69 and SI75 used in the prior art, and the increased risk of compound scorch from disulfide silane coupling agents.

[0027] 3-octanoylthio-1-propyltriethoxysilane is used as a coupling agent, its sulfur content is low, and the stability of the generated sulfur-carbon...

Abstract

The invention relates to a belted layer steel wire cord seam gum. A certain quantity of special silane coupling agent is added into the formulation of the seam gum which uses a great deal of white carbon black, so that the mooney viscosity of glue stock can be effectively reduced, thus reducing the segments of mixing, decreasing the hysteresis loss of glue stock and improving the bonding performance between the glue stock and steel wires. The belted layer steel wire cord seam gum comprises the components with the mass proportion: 100 parts of natural rubber, 40-50 parts of carbon black, 10-15parts of white carbon black, 8-12 parts of zinc oxide, 1.2 parts of decanoate cobalt, 2.5 parts of age inhibitor, 1.5 parts of hydroxyphenol, 5 parts of insoluble brimstone, 5 parts of adhesion promoter and 1.2 parts of sulfonamides accelerant; and 1-2.5 parts of sulpho-carboxylic ethers silane coupling agent is added into the formulation.

Description

technical field [0001] The invention relates to a special adhesive, which is specifically applied to the bonding of belt steel cords in the process of manufacturing tires, and belongs to the field of rubber tire manufacturing. Background technique [0002] In the existing process of manufacturing all-steel tires, there are many kinds of adhesive glues used for belt layer steel cords. The currently used adhesive compound formula uses a large number of silica, which brings more serious problems to subsequent processes such as compound refining, extrusion, and calendering. [0003] That is to say, the Mooney viscosity of the processed compound is relatively high, and the dispersibility of silica is poor. Due to the rapid heat generation of the rubber material, a multi-stage master batching process is required, which affects the full play of the performance of the belt layer adhesive rubber material, increases the cost of rubber material production and processing, and the adhes...
