Problems solved by technology

[0002] Bias tires generally use nylon cord as the carcass skeleton material. The nylon cord hanging glue of the basic layer of the existing tire carcass mostly uses natural rubber and styrene-butadiene rubber as rubber raw materials. Not only the cost of the rubber material is high, but also The heat generation of the rubber is also high, and it is easy to be thermally aged, so that the quality problem of delamination between the rubber and the cord, or delamination between the layers is easy to occur in the base layer when the tire is used.

Embodiment 1

[0037] The rubber is mixed according to the components specified in Table 2 below, and the mixing of the rubber is carried out in two stages. The first stage of mixing is carried out in the BB370 type internal mixer, and the second stage of mixing is carried out in the XHM-140 type internal mixer and the XKY-600 tablet press. The order of addition is the conventional order of addition. Then the properties of the obtained compound were tested, and the test results are listed in Table 2.

Embodiment 2

[0039] Carry out rubber mixing by each component specified in the following Table 2, the mixing of the rubber material is the same as in Example 1, and the test results are listed in Table 2.

Embodiment 3

[0041] Carry out rubber mixing by each component specified in the following Table 2, the mixing of the rubber material is the same as in Example 1, and the test results are listed in Table 2.

Abstract

The invention discloses a cord thread rubber compound for a basic layer of an automobile tire. The rubber compound is prepared from natural rubber, butadiene rubber and butadiene styrene rubber serving as main materials and adhesion promoter AIR-1, general carbon black, reinforcing agent HDP, pine tar, insoluble sulfur and sulfenamide accelerators serving as main auxiliary materials in a scientific and rational proportion. Compared with the prior art, the cord thread rubber compound for the basic layer of the automobile tire has high adhesion strength with nylon cord thread and high adhesion retention rate after thermal ageing, and meanwhile has low raw material cost; the quality problems such as delaminating and bulging cannot occur on the basic layer part of the tire in the use of the tire; and the tire is safe to use.

Description

technical field [0001] The invention relates to a nylon cord hanging glue for a basic layer of car tire carcass, and belongs to the field of tire manufacturing. Background technique [0002] Bias tires generally use nylon cord as the carcass skeleton material. The nylon cord hanging glue of the basic layer of the existing tire carcass mostly uses natural rubber and styrene-butadiene rubber as rubber raw materials. Not only the cost of the rubber material is high, but also The heat generation of the rubber is also high, and it is easy to be thermally aged, so that the quality problem of delamination between the rubber and the cord, or between the layers is easy to occur in the base layer when the tire is used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a car tire carcass basic layer cord coating with low cost, firm combination of rubber material and cord, and low heat generation. The sizing material can bett...
