Embodiment 1

[0021] The preparation method of a high-temperature-resistant and corrosion-resistant environmentally friendly rubber of this embodiment is made of the following raw materials in parts by mass: it is made of the following raw materials in parts by mass: natural rubber 85-95, stabilizer 15 -20, nitrile rubber 10-20, modified neoprene rubber 30-45, carbon black 20-26, polystyrene 7-16, vulcanizing agent 0.5-1.5, stearic acid 2-4, zinc oxide 2-8 , magnesium oxide 12-18, antioxidant 9-16, flame retardant 15-25, paraffin 20-30, accelerator 4-5; its preparation method comprises the following steps:

[0022] Step S1: weighing each component according to the above parts by weight;

[0023] Step S2: Add all the components into the mixing container, place the mixing container in the sonicator, start the sonicator, and turn off the sonicator after 15-20 minutes;

[0024] Step S3: transfer to the mill for extrusion molding;

[0025] Step S4: Transfer to vulcanization machine for vulcani...

Embodiment 2

[0028] 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.

[0029] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0031] This embodiment is further optimized on the basis of embodiment 2, and the anti-aging agent is CTU anti-aging agent. It has excellent protective effect on ozone cracking and flex fatigue aging, and also has good protective effect 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. The use of anti-aging agent CTU makes it have good performance in thermal oxidation resistance, and the performance of the compound containing anti-aging agent CTU is higher than that of other anti-aging agents in terms of rate of change in elongation, rate of change in elongation at break, and change in hardness. agent of rubber.

[0032] Other parts of this embodiment are the same as those of Embodiment 2, so details are not repeated here.

Abstract

The invention discloses a preparation method of high-temperature-resistant and corrosion-resistant environment-friendly rubber. The high-temperature-resistant and corrosion-resistant environment-friendly rubber is prepared from the following raw materials in parts by mass: 85-95 of natural rubber, 15-20 of stabilizer, 10-20 of acrylonitrile-butadiene rubber, 30-45 of modified chloroprene rubber, 20-26 of carbon black, 7-16 of polystyrene, 0.5-1.5 of sulfurizing agent, 2-4 of stearic acid, 2-8 of zinc oxide, 12-18 of magnesium oxide, 9-16 of anti-aging agent, 15-25 of flame retardant, 20-30 ofparaffin and 4-5 of accelerant. The temperature-resistant and corrosion-resistant environment-friendly rubber prepared by using the simple preparation method is not only low in rubber cost and good inchemical corrosion resistance effect, but also simple in preparation process and easy to realize industrialization; in addition, the high-temperature-resistant and corrosion-resistant environment-friendly rubber has excellent stability and heat resistance and is nontoxic, environment-friendly, capable of effectively reducing environment pollution and long in service life.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a method for preparing 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 t...
