Embodiment

[0045] Carcass cord formula raw material details:

[0046]Import SVR10# (Vietnam) mixture A;

[0047] N330 carbon black, product of Shanghai Cabot Chemical Company;

[0048] Softening oil, TDAE, Hansheng chemical products;

[0049] The rest of the raw materials are commercially available industrial grade products.

[0050] After kneading according to the above carcass cord formula, the compounded rubber is calendered and coated with carcass cord, and the electron-irradiated and non-electron-irradiated cords are sampled respectively, which are recorded as electron-irradiated samples 1-5 and non-electron-irradiated samples in sequence. Sample 1~5;

Abstract

The invention belongs to the technical field of rubber detection, and particularly relates to an evaluation method and device for pre-crosslinking of a carcass ply rubber compound and a computer readable carrier medium. According to the evaluation method for pre-crosslinking of the carcass ply rubber compound, the elastic modulus and the viscous modulus obtained through strain scanning of a rubber processing analyzer are used for drawing corresponding to strain changes, a curve not only can reflect the modulus, but also can visually distinguish the elastic modulus and the viscous modulus of the rubber compound, and therefore the pre-crosslinking of the carcass ply rubber compound is evaluated. And deducing the pre-crosslinking rate of the carcass ply after electron irradiation according to the curve area. The method provided by the invention is simple to operate, high in sensitivity, accurate and reliable in test result and free of environmental pollution.

Description

technical field [0001] The application belongs to the technical field of rubber detection, and in particular relates to an evaluation method, equipment and computer-readable carrier medium for carcass cord compound rubber pre-crosslinking. Background technique [0002] The automobile industry is developing rapidly all over the world, and automobile tires are an important part of vehicles, and their quality and performance directly affect the performance of vehicles. The radial tire carcass ply is a carcass layer composed of rubber-coated cord fabric, which is the stressed skeleton layer of the tire. Radial tires are classified according to the material of the carcass skeleton. The carcass is called all-steel tires with steel wires, which are generally used for commercial truck tires; [0003] At present, the passenger car tires in the market have poor maneuverability and high rolling resistance, and there is an urgent need for a carcass cord with high fatigue resistance and...
