[0060] 2. Preparation of alkylphenol sulfides

[0061] Unless otherwise stated, the softening point was tested according to ASTM D3461-14, and the sulfur content was tested according to GB T4497.1-2010.

Embodiment 1

[0063] Add 99g (0.5mol) of styrenated phenol and 92g of toluene into a 250ml reaction bottle equipped with a stirring device, a thermometer and a reflux condenser, and gradually add 61g of S 2 Cl 2 (0.45mol), while gradually raising the temperature to 85°C, reflux reaction for 2h, and then raising the temperature to 170°C for vacuum distillation to obtain the product with a softening point of 82.6°C and a sulfur content of 23.9%.

Embodiment 2

[0065] Add 79.2g (0.4mol) of styrenated phenol, 10.8g (0.1mol) of p-cresol, and 92g of toluene into a 250ml reaction flask equipped with a stirring device, a thermometer and a reflux condenser, and gradually add 61g of S 2 Cl 2 (0.45mol), while gradually raising the temperature to 85°C, reflux reaction for 2h, and then raising the temperature to 165°C for vacuum distillation to obtain the product with a softening point of 89.6°C and a sulfur content of 25.7%.

Abstract

The invention relates to alkylphenol sulfide. The alkylphenol sulfide is obtained by reacting alkylphenol with sulfur chloride. When the alkylphenol sulfide serves as a sulfur donor to be used for rubber materials, the aging characteristic of rubber can be improved obviously. The structure of the alkylphenol sulfide is shown as formula (1): (please see the specification for the formula).

Description

technical field [0001] The invention relates to an alkylphenol sulfide used in the rubber industry, a preparation method and application thereof. The alkylphenol sulfide is especially suitable for improving the aging resistance of rubber. Background technique [0002] Rubber materials are one of the important basic materials in social life. Rubber materials are used in various aspects of social life, such as automobile tires, sealing materials, conveyor belts, shock-absorbing materials, electrical insulation materials, etc. Since most of the rubber is an organic polymer, the rubber is affected by oxygen, temperature, humidity, metal ions, etc. in the environment during use, and its performance will decline, eventually causing the rubber material to be damaged and unusable. Therefore, the aging of rubber materials is an important topic in rubber research. [0003] One of the methods to improve the aging properties of rubber is to use highly efficient sulfur donors to improve...
