Embodiment 1

[0036] A kind of antistatic rubber, component and mass parts are as follows:

[0037]

[0038]

[0039] Described stearic acid is stearic acid 1801, stearic acid 1837 or stearic acid 1842. Its stearic acid uses animal fat as the main raw material. Furthermore, the composite carbon black is compounded from conductive carbon black, carbon black N330 and carbon black N774, and the ratio of parts by mass is (1-3):2:(1-3). The proportion used here is 1:2:1. N774 is suitable for all kinds of rubber with large particle size. The product particle size is 80-170nm and carbon black with low structure. It is mostly used for the buffer layer and ply rubber of tire carcass. , rubber hose, extruded products, various industrial rubber products, and wires, cables, etc., N774 can be filled in a large amount in the rubber without affecting the vulcanization characteristics of the rubber too much. The vulcanized rubber has high elongation, low heat generation, and high elasticity. , Good a...

[0051] A kind of antistatic rubber, component and mass parts are as follows:

[0052]

[0053] Described stearic acid is stearic acid 1801, stearic acid 1837 or stearic acid 1842. Its stearic acid uses animal fat as the main raw material. The composite carbon black is compounded from conductive carbon black, carbon black N330 and carbon black N774, and the ratio of parts by mass is 3:2:3. N774 is suitable for all kinds of rubber, with large particle size, product particle size of 80-170nm, and low structure carbon black varieties. It is mostly used for buffer layer and ply rubber of tire carcass, rubber hose, extruded products, and various industrial rubber Products, as well as wires, cables, etc., N774 can be filled in a large amount in the rubber without affecting the vulcanization properties of the rubber too much. The vulcanized rubber has high elongation, low heat generation, high elasticity, and good aging resistance. The composite carbon black is acetylene carbon b...

Embodiment 3

[0057] Based on embodiment 1 or 2, embodiment 3 can also add high styrene resin therein to improve hardness, the mass fraction of addition ratio and conductive carbon black is 1:1, every time adding 1 part of high styrene resin rubber hardness improves about 1 Spend.

[0058] High styrene resins have a styrene content of 70%-90%. High styrene rubber is a special variety of styrene-butadiene rubber. It is latex produced by copolymerization of butadiene and styrene emulsion, then coagulated, washed, extruded and dehydrated, and dried to obtain the product. The styrene content in general styrene-butadiene rubber is 23.5 % ± 1%, the content is as high as 40% or more called high styrene rubber, combined with styrene 70% -90% is called high styrene resin. In this scheme, high styrene resin is used as a rubber additive for rubber production, which can improve the modulus, strength, hardness, tear resistance, flexion resistance and wear resistance of rubber, and the shape is about 3m...

Abstract

The invention discloses an anti-static rubber and a preparation method thereof and belongs to the field of rubber manufacturing. The anti-static rubber and the preparation method thereof aim at solving the problems of anti-static deficiency, poor physical performance and low heat generation rate in the prior art. The anti-static rubber is a compound conductive carbon black composition combined with anti-static agent, thereby effectively guaranteeing anti-static effects, improving wear resistance; compounded carbon black is low in heat value during operation and can ensure hardness and ductility of the anti-static rubber. By means of a two-section plastifying manner and through synergistic effects of the compounded carbon black and the anti-static agent, the anti-static rubber achieves good anti-static effects, excellent physical performance, good hardness and tensile strength, low heat value and simple production processes.

Description

technical field [0001] The invention relates to the field of rubber roller manufacture, and more specifically relates to an antistatic rubber and a preparation method thereof. Background technique [0002] Rubber is an electrical insulating material, and when its surface is rubbed, static electricity builds up in a static state. When electric charge accumulates to certain amount, just releases with spark form. When the amount of discharge is slight, it will not cause harm to the human body, but when the discharge reaches a certain level, it will cause electric shock. In order to ensure personal safety, the rubber used in this case must be antistatic rubber that can remove static electricity. The dangers caused by static electricity generally include the following: [0003] (1) When the static electricity is discharged, if there is fire, flammable and explosive materials around, it will cause a fire; for example, the friction between the belt and the roller conveyed by the ...
