Embodiment 1

[0022] A kind of high-temperature-resistant and corrosion-resistant environmental protection rubber of the present embodiment is made of the following raw materials in terms of mass parts: natural rubber 80-100, stabilizer 8-15, modified chloroprene rubber 20-50, nitrile rubber 25-40, carbon black 15-30, polystyrene 8-12, vulcanizing agent 1-1.5, stearic acid 2-4, zinc oxide 5-10, magnesium oxide 12-18, antioxidant 10-14, flame retardant Agent 15-25, paraffin 20-30, accelerator 4-5.

[0023] Its production method is:

[0024] Step S1: weighing each component according to parts by weight;

[0025] Step S2: Add all components into a mixing container, place the mixing container in a sonicator, start the sonicator, wait for 15-20 minutes, turn off the sonicator.

[0026] Step S3: transfer to an open mill for extrusion molding.

[0027] Step S4: transfer to a vulcanizing machine for vulcanization and molding, wherein the set pressure is 10MPa-12MPa, the temperature is 150-180°C,...

Embodiment 2

[0030] This embodiment is further optimized on the basis of embodiment 1, and the vulcanizing agent is one of sulfur and dicumyl peroxide or a combination of sulfur and dicumyl peroxide. Through the "bridging" of the vulcanizing agent, it becomes a three-dimensional network structure, so that the mechanical and physical properties of the rubber are significantly improved. It can not only make the product have excellent insulation and processing performance, but also improve its heat resistance and weather resistance of the product.

[0031] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0033] This example is further optimized on the basis of Example 2. The anti-aging agent is N-phenyl-α-aniline, N-phenyl-N'-isopropyl-p-phenylenediamine, N-N' - one or more of diphenyl-p-phenylenediamine, antioxidant 4020. One of N-phenyl-α-aniline, N-phenyl-N'-isopropyl-p-phenylenediamine, N-N'-diphenyl-p-phenylenediamine, antioxidant 4020 or A variety of anti-aging agents can have excellent protective effects on ozone cracking and flex fatigue aging, and also have good protective effects on heat, oxygen, copper, manganese and other harmful metals. Used in tires, tapes and general industrial rubber products. And it has a wide range of applications, and can be used for nitrile rubber, chlorine rubber, styrene-butadiene rubber, AT; NN, natural rubber, etc.

[0034] Other parts of this embodiment are the same as those of Embodiment 2, so details are not repeated here.

Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant environment-friendly rubber, which is made of the following raw materials in parts by mass: 80-100 natural rubber, 8-15 stabilizer, 25-40 nitrile rubber, and modified chloroprene rubber 20‑50, carbon black 15‑30, polystyrene 8‑12, vulcanizing agent 1‑1.5, stearic acid 2‑4, zinc oxide 5‑10, magnesium oxide 12‑18, antioxidant 10‑14, flame retardant Agent 15‑25, paraffin wax 20‑30, accelerator 4‑5. The temperature-resistant and corrosion-resistant environmentally friendly rubber is prepared by a simple preparation method. Not only the rubber cost is low, the chemical corrosion resistance is good, but also the preparation process is simple, easy to industrialize, and has excellent stability, heat resistance, and non-toxic , Environmental protection, can effectively reduce environmental pollution, long service life.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a high-temperature-resistant and corrosion-resistant environment-friendly rubber. Background technique [0002] Rubber Highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. Rubber is a highly elastic polymer, its molecular structure is chain, and the molecular chain has high flexibility. The molecular chain of rubber can be cross-linked (vulcanized), and the cross-linked material has the ability to recover quickly when it is deformed by an external force, and has good physical and mechanical properties and chemical stability. Only through cross-linking ...
