Embodiment 1

[0033] Example 1 Preparation of environmentally friendly rubber reinforcing agent

[0034] Proceed as follows:

[0035] (1) Preparation of raw materials: the recovered paint slag, remove the impurities visible to the naked eye, and stand by;

[0036] (2) High temperature pyrolysis: Mix the paint slag with fly ash removed from mechanical impurities in a ratio of 50:50, then send it to a high temperature furnace and heat it to 800°C, maintain it for 2 hours and then naturally cool down.

[0037] (3) ball milling and sieving: 100 parts of step (2) products obtained therefrom are mixed with 10 parts of white carbon black and 1 part of graphene at high speed, after mixing, ball milled by a ball mill for 3 hours, finally crossed a 500 mesh sieve to obtain a kind of black solid powder. The black solid powder is an environmentally friendly rubber reinforcing agent.

Embodiment 2

[0038] Example 2 Preparation of environmentally friendly rubber reinforcing agent

[0039] Proceed as follows:

[0040] (1) Preparation of raw materials: the recovered paint slag, remove the impurities visible to the naked eye, and stand by;

[0041] (2) High-temperature pyrolysis: Mix 100 parts of paint slag with mechanical impurities removed with 50 parts of fly ash, then send it to a high-temperature furnace and heat it to 800°C, maintain it for 2 hours, and then naturally cool down.

[0042] (3) ball milling and sieving: the product obtained in step (2) is mixed at high speed with 15 parts of white carbon black and 2 parts of graphene, and after mixing, it is ball-milled by a ball mill for 4 hours, and finally crosses a 500-mesh sieve to obtain a black solid powder. The black solid powder is an environmentally friendly rubber reinforcing agent.

Embodiment 3

[0043] Example 3 Preparation of environmentally friendly rubber reinforcing agent

[0044] Proceed as follows:

[0045] (1) Preparation of raw materials: the recovered paint slag, remove the impurities visible to the naked eye, and stand by;

[0046] (2) High-temperature pyrolysis: Mix 50 parts of paint slag with mechanical impurities removed with 100 parts of fly ash, then send it to a high-temperature furnace and heat it to 800°C, maintain it for 2 hours, and then naturally cool down.

[0047] (3) ball milling and sieving: the product obtained in step (2) is mixed at high speed with 20 parts of white carbon black and 3 parts of graphene, and after mixing, it is ball-milled by a ball mill for 2 hours, and finally crosses a 500-mesh sieve to obtain a black solid powder. The black solid powder is an environmentally friendly rubber reinforcing agent.

Abstract

The invention discloses an environment-friendly rubber reinforcing agent and a preparation method thereof.The preparation method comprises the steps that recycled waste paint slag is subjected to mechanical impurity removal and then mixed with fly ash according to a certain proportion, then the mixture is fed into a high-temperature furnace to be heated to the temperature not lower than 800 DEG C, the temperature is maintained for not less than 2 hours, and then natural cooling is conducted; and cooling to room temperature, taking out, mixing with a proper amount of white carbon black and graphene at a high speed, ball-milling for 2-4 hours by a ball mill after mixing, and finally sieving by a 500-mesh sieve to obtain black solid powder. The solid powder has a certain reinforcing effect on rubber and can be used as a reinforcing agent. The method has the advantages that the paint slag is well recycled, the recycling process is environment-friendly, simple and feasible, the production cost is reduced, the method has a good development prospect, and an economic and effective method is provided for recycling the paint slag.

Description

technical field [0001] The invention relates to an environment-friendly rubber reinforcing agent and a preparation method thereof, belonging to the technical field of powder filling reinforcing agent. Background technique [0002] For general synthetic rubber and natural rubber, its tensile strength and tensile stress are very low, and it is difficult to manufacture products with use value. Therefore, reinforcement is required, and reinforcement is a function of significantly improving the tensile strength, tear strength, abrasion, etc. of the rubber at the same time. Commonly used reinforcing agents are carbon black, silica and reinforcing resins. Among them, carbon black is the most commonly used because of its low price. However, the production of carbon black will bring serious environmental pollution problems, and efforts should be made to reduce the use of carbon black. [0003] CN109134932A, Modified fly ash for reinforcing rubber products and preparation method th...
