Problems solved by technology

However, these multi-functional additives are expensive and used in large amounts, and the activation effect is poor. Many of them need to be heated and melted to a state that is easy to transport before use. The energy consumption is high, the use is inconvenient, and the performance indicators of the prepared regenerated rubber are not ideal.

Embodiment 1

[0020] An environment-friendly multifunctional regeneration agent, comprising the following components in parts by weight: 4 parts of softening agent, 0.5 parts of alkylphenol disulfide, 1.5 parts of thickening and strengthening agent, 2 parts of animal and vegetable oleic acid, and the softening agent is natural Phenols, cashew nut oil is preferred in this embodiment, and the alkylphenol disulfide is a mixture of one or more of activator 420, activator 450, activator 480, activator 560, and activator 910. Among them, activator 480 is preferred, rosin is the thickening and reinforcing agent, and animal and vegetable oleic acid is pine tar, tall oil, palm oil, etc., and vegetable oil residue or vegetable asphalt produced by other industries. In this embodiment, palm oil is preferred.

[0021] Preparation method: Heat the cashew nut oil to 130°C in a stirring tank, melt the alkylphenol disulfide in an oven at 80°C to a liquid state that is easy to flow, and then add the two into ...

Embodiment 2

[0023] An environment-friendly multifunctional regeneration agent, comprising the following components in parts by weight: 1 part of softening agent, 1 part of alkylphenol disulfide, 3 parts of thickening and reinforcing agent, softening agent is cashew nut oil, alkylphenol disulfide Choose activator 420 as the sulfide, and choose rosin as the thickening and reinforcing agent.

[0024] The preparation method is the same as in Example 1.

Embodiment 3

[0026] An environment-friendly multifunctional regeneration agent, comprising the following components in parts by weight: 3.4 parts of softening agent, 0.6 part of alkylphenol disulfide, 1 part of thickening and strengthening agent, 10 parts of animal and vegetable oleic acid, and the softening agent is cashew nut Shell liquid, alkylphenol disulfide chooses activator 910, thickener chooses rosin, animal and vegetable oleic acid chooses pine tar.

[0027] The preparation method is the same as in Example 1.

[0028] Comparative experiment one:

[0029] The control group used regenerants: in parts by weight, 10 parts of softener, 0.2 parts of alkylphenol disulfide, 1.5 parts of thickener and reinforcing agent, and 2 parts of animal and vegetable oleic acid were added to the reclaimed rubber powder respectively.

Abstract

The invention discloses an environment-friendly multifunctional regenerant and a preparation method thereof. The environment-friendly multifunctional regenerant comprises the following components: inparts by weight, 1-4 parts of a softener and 0.5-1 part of alkylphenol disulfide, wherein the softener is natural phenol, preferably Anacardium occidentale oil or an Anacardium occidentale shell liquid. According to the structural characteristics of different functional auxiliaries including softeners, activators and other auxiliaries, multiple auxiliaries are combined into a uniform and stable additive through the synergistic effect of the functional auxiliaries in the production process of recycled rubber, therefore, the complicated mixing procedure before production is optimized, and convenience for production, use, measurement and transfer is achieved due to the multifunctional regenerant at an easy-flowing liquid state at room temperature.

Description

technical field [0001] The invention relates to the technical field of reclaimed rubber, in particular to an environmentally friendly multifunctional regenerant and a preparation method thereof. Background technique [0002] The low-end and backward production technology of recycled rubber has always been a common state in the industry. For a long time, various production companies have used coal tar and other mineral softeners as auxiliary agents for the production of recycled rubber. There is a large pungent smell in the production process, which cannot Clean production is realized, and the production of environmentally friendly recycled rubber cannot be realized, and there is very large pollution. In the past two years, with the gradual strengthening of national environmental protection policies and the enhancement of people's awareness of environmental protection, coal tar has been gradually eliminated. At present, aromatic oil and other petroleum-based additives are use...
