Problems solved by technology

Rubber needs to be added with reinforcing agent and colorant during the production process, which will often cause a lot of dust pollution and noise pollution to the environment during the mixing process, and in order to handle the dispersion well, it will also consume a lot of energy
At present, there is no good way to solve the above pollution in China.
Some rubber product manufacturers use internal mixers to mix and then use open mills to process the dispersion mode. This type of mode requires high equipment investment costs, high energy consumption, and high entry barriers; some directly use open mixers to add color paste, but The cost of color paste is high, and the color is not easy to control

Embodiment 1

[0011] Weigh 26.5 parts of styrene-butadiene rubber 1502, 17.5 parts of silicon dioxide, 5 parts of naphthenic rubber softening oil, 0.25 parts of antioxidant 264, 0.75 parts of zinc stearate, put it into a 110L internal mixer and press it for 10 minutes to open Cool the circulating water so that the temperature is controlled at 80±10°C, and continue to mix for 10 minutes, then take out and cool to form a premixed rubber compound.

[0012] Put the premixed rubber compound, 35 parts of sun-fast bright red BBS, 15 parts of calcium carbonate into a 110L mixer for 5 minutes, turn on the cooling circulating water, control the temperature at 80±10℃, and continue mixing for 10 minutes. Then take it out, thinly pass it 5 times on the double stick mill (the double stick mill should be cooled by cooling water), and then evenly sprinkle talcum powder on the rubber cutting machine, and lay the pull piece on the cutting machine to cut strips , according to 20KG standard packing.

Embodiment 2

[0014] Weigh 34 parts of styrene-butadiene rubber 1502, 12.5 parts of 800 mesh calcium carbonate, 12.5 parts of naphthenic rubber softening oil, 0.25 parts of antioxidant 264, 0.75 parts of zinc stearate, put into a 110L internal mixer and pressurized for 10 minutes Turn on the cooling circulating water, control the temperature at 80±10℃, continue to mix for 10 minutes, take it out and cool it to become a premixed rubber compound.

[0015] Put the premixed rubber compound, 30 parts of N300 carbon black, and 10 parts of 800 mesh calcium carbonate into a 110L mixer for 5 minutes, turn on the cooling circulating water, control the temperature at 80±10°C, and continue mixing for 10 minutes. Then take it out, thinly pass it 5 times on the double stick mill (the double stick mill should be cooled by cooling water), and then evenly sprinkle talcum powder on the rubber cutting machine, and lay the pull piece on the cutting machine to cut strips , according to 20KG standard packing.

Embodiment 3

[0017] Weigh 44 parts of styrene-butadiene rubber 1502, 15 parts of naphthenic rubber softening oil, 0.25 parts of antioxidant 264, and 0.75 parts of zinc stearate, put them into a 110L internal mixer for 10 minutes, turn on the cooling circulating water, and make the temperature Control at 80±10℃, continue to mix for 10 minutes, take out and cool to become premixed rubber.

[0018] Put the pre-mixed rubber material and 40 parts of carbon black into the 110L internal mixer for 5 minutes, turn on the cooling circulating water, control the temperature at 80±10℃, and take it out after continuous mixing for 10 minutes. On the machine (the double-bar open mill should pay attention to cooling by cooling water), after thinning 5 times, pull the sheet, evenly sprinkle talcum powder on the rubber cutting machine, lay the pull sheet flat on the cutting machine and cut it into strips, and pack it according to the 20KG standard.

Abstract

The invention discloses a method for preparing a colored rubber sheet for rubber, which comprises the following steps of: putting synthetic rubber, a rubber reinforcing agent, a rubber softener, an antiaging agent and a lubricating agent into a banbury mixer for premixing; cooling a premixed rubber material completely, and adding pigment color concentrates and the rubber reinforcing agent for banburying; and wrapping the color concentrates, cooling, and milling on an open mill for multiple times to obtain the high-concentration and high-dispersion colored rubber sheet for the rubber. By the colored rubber sheet, the pollution of dust such as the color concentrates, the reinforcing agent and the like to an environment can be avoided greatly, energy waste can be reduced, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention belongs to the field of plastic coloring, and particularly relates to a preparation method of a color film for rubber. Background technique [0002] At present, the relevant state departments are understanding and studying the situation of the "two high and one capital" industries, and the pollution situation of the rubber processing industry has also attracted the attention of the society. In the production process of rubber, reinforcing agents and colorants need to be added, which often cause a lot of dust pollution and noise pollution to the environment during the mixing process, and also consume a lot of energy in order to disperse well. At present, there is no good way to solve the above pollution in China. Some rubber product manufacturers use an internal mixer to mix and then use an open mill to process dispersion. This type of equipment has high investment costs, high energy consumption, and high barriers to entry; some directly ...
