Embodiment 1

[0018] Concentrate the waste toner of printers and copiers, use a 20-mesh standard sieve to sieve and remove impurities from the waste toner, add 5wt% Mg(OH) 2 and 0.8wt% engine oil, mixed evenly, activated, the activation time is 2h, and dried at 65°C to prepare the filling reinforcing agent. The above-mentioned filling and reinforcing agent was added to the raw material EPDM rubber, and EPDM rubber was prepared according to the traditional rubber preparation process. The commonly used filling and reinforcing agent carbon black was used as a comparison. Its properties are shown in Table 1.

[0020]

Embodiment 2

[0022] Concentrate the waste toner of printers and copiers, use a 20-mesh standard sieve to sieve and remove impurities from the waste toner, add 2.5wt% Mg(OH) 2 , 1.5wt% Ca(OH) 2 and 0.5wt% engine oil, mix evenly, activate, the activation time is 2.5h, and dry at 105°C to prepare the filling reinforcing agent. Add the above-mentioned filling and reinforcing agent to the raw material styrene-butadiene rubber, and prepare styrene-butadiene rubber according to the traditional rubber preparation process. The commonly used filling and reinforcing agent carbon black is used as a comparison, and its properties are shown in Table 2.

Embodiment 3

[0026] Concentrate the waste toner of printers and copiers, use a 20-mesh standard sieve to sieve and remove impurities from the waste toner, add 1.0wt% Mg(OH) 2 , 1.0wt% Ca(OH) 2 , 1.0wt%Al(OH) 3 and 0.2wt% engine oil, mixed evenly, activated for 3 hours, and dried at 85°C to obtain a filling reinforcing agent. The above-mentioned filling and reinforcing agent was added to the raw material nitrile rubber, and the nitrile rubber was prepared according to the traditional rubber preparation process. The commonly used filling and reinforcing agent carbon black was used as a comparison, and its properties are shown in Table 3.

[0027] table 3

[0028]

[0029] In summary, as a filling and reinforcing agent for rubber, the treated waste carbon powder is equivalent to pure carbon black, which can effectively improve the tensile strength and hardness of rubber products, reduce its wear, and can be used as a source Wide range of low cost rubber filled reinforcements.

Abstract

The invention relates to a resource utilization method of a waste toner in a printer and a copying machine. The resource utilization method comprises the following steps: recycling to centralize, screening to remove impurities, mixing, activating, drying, and packaging. The resource utilization method has the beneficial effects that the process is simple, the operation is convenient, the recycling cost is low and the recycling utilization rate is high; the waste toner can be used as a filling reinforcing agent of rubber, the function and the effect are identical to those of pure carbon black, the tensile strength and hardness of a finished rubber product are effectively improved, and the abrasion consumption of the finished rubber product is reduced.

Description

technical field [0001] The invention relates to a resource utilization method of waste toner in printers and copiers. Background technique [0002] With the development of modern office automation, the number and frequency of printers and copiers are increasing day by day. When the toner cartridge in the printer or the toner cartridge in the copier reaches the end of its service life or is damaged, generally 20 to 40% of waste toner will remain in the storage container of the toner cartridge, and most manufacturers will recycle it, and then Centralized in the form of incineration, a small number of customers are afraid of trouble or even discarded directly. Since waste toner is usually composed of resin, carbon black, magnetic iron oxide, charge control particles, lubricants and plasticizers, if it is burned, it is easy to produce carcinogenic exhaust gases such as carbon monoxide and dioxin, which is harmful to the atmosphere, environment and people. It will cause great d...
