Embodiment 1

[0020] Example 1: Take 1 kg of the fraction of vacuum residue oil at 480-560 °C as raw material, heat it to 270 °C at a rate of 3 °C / min, add 40 g of dicumyl peroxide (DCP) as a free radical initiator, and simultaneously start from the reaction Oxygen is fed into the bottom of the device, and the flow rate of oxygen is 12L / h. After reacting for 8 hours, an environment-friendly petroleum-based rubber softening functional material was obtained.

Embodiment 2

[0021] Example 2: Take 1kg of the fraction of vacuum residue oil at 480-560°C as raw material, heat it to 210°C at a rate of 4°C / min, add 45g of free radical initiator benzoyl peroxide, and simultaneously feed Oxygen, the oxygen flow rate is 16L / h. After 10 hours of non-catalytic oxidation reaction, an environment-friendly petroleum-based rubber softening functional material was obtained.

Embodiment 3

[0022] Example 3: Take 1kg of the fraction of vacuum residue oil at 480-560°C as raw material, heat it to 260°C at a rate of 5°C / min, add 50g of free radical initiator cyclohexanone peroxide and tert-butyl hydroperoxide , while feeding oxygen from the bottom of the reactor, the oxygen flow rate is 18L / h. After 12 hours of non-catalytic oxidation reaction, an environment-friendly petroleum-based rubber softening functional material was obtained.

Abstract

The invention relates to a preparation method of an environment-friendly petroleum-base rubber softening functional material, belonging to the fields of environmental protection and petroleum processing. The scheme is as follows: the method comprises the following steps: by using the 480-560 DEG C fraction of vacuum residues as the raw material, heating to the reaction temperature of 200-280 DEG C at the rate of 3-5 DEG C / minute, adding a free-radical initiator, introducing oxygen to carry out non-catalytic oxidation, and sufficiently stirring to react for 8-14 hours to obtain the environment-friendly petroleum-base rubber softening functional material, wherein the addition amount of the free-radical initiator is 4-6 wt% of the vacuum residues. Under the action of the free-radical initiator, the oxygen-blast non-catalytic oxidation technique is utilized to prepare the petroleum-base rubber softening functional material which has favorable compatibility with rubber and conforms to the requirements for environmental protection. The method is simple and economic; and the obtained rubber softening functional material has the advantages of stable properties and favorable compatibility with rubber, and conforms to the requirements for environmental protection.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly petroleum-based rubber softening functional material in the fields of environmental protection and petroleum processing. Background technique [0002] Rubber softening functional material is a kind of rubber processing aid, which aims to improve the performance of rubber processing. Its addition can reduce the viscosity of the rubber compound and the temperature during mixing, increase the plasticity, fluidity and adhesion of the rubber compound, and improve the physical properties of the rubber. Therefore, softening functional materials are of great significance in rubber processing. There are many varieties of rubber softening functional materials in use at present, which are mainly divided into petroleum, coal tar, fatty oil and pine tar according to their sources. Among them, petroleum softening functional materials have become a popular choice due to their abundant resources...
