[0062] 2. Preparation of alkylphenol sulfides

[0063] 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

[0065] Add 79.2g (0.4mol) of styrenated phenol, 30.2g (0.1mol) of distyrenated phenol, and 90g of toluene into a 500ml reaction flask equipped with a stirring device, a thermometer and a reflux condenser, and gradually add 64.8g of S 2 Cl 2 (0.48mol), 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 84.6°C and a sulfur content of 23.7%.

Embodiment 2-5

[0067] The preparation process of the resin in Example 1 was repeated except changing the molar ratio of raw materials styrenated phenol and distyrenated phenol. See Table 2 below for specific data.

Abstract

The invention relates to alkylphenol sulfide. Reaction is carried out on mono-substituted and bis-substituted mixed alkylphenol and sulfur chloride to obtain the alkylphenol sulfide. The structure of the alkylphenol sulfide is shown. The alkylphenol sulfide has the advantages that the alkylphenol sulfide can be applied to rubber as an effective sulfur donor when the alkylphenol sulfide is used as a sulfur donor for rubber materials, and accordingly rubber compositions are excellent in mechanical properties, anti-reversion behavior and ageing resistance.

Description

technical field [0001] The invention relates to an alkylphenol sulfide used in the rubber industry, its preparation method and application. The alkylphenol sulfide has a certain anti-vulcanization reversion effect, and is especially suitable for improving the aging resistance of rubber, which can make the rubber The anti-aging performance of the material has been significantly improved. 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 import...
