Problems solved by technology

When ordinary rubber products are in contact with or combined with metal products, the rubber has no antirust protection effect on the metal, and the metal material is easy to rust when the humidity is high or the storage time is long, and some additives or additives in the rubber are also harmful to the metal. certain corrosiveness
These conditions lead to the frequent scrapping and replacement of metal parts due to corrosion, resulting in certain economic losses
Especially some weapons and equipment, such as artillery muzzles, are generally sealed with rubber plugs to achieve dustproof and waterproof purposes, but during long-term storage, the parts that contact the rubber plugs cannot be protected against rust and rust occurs sometimes
[0003] At present, most of the rubber used in direct contact with metal can take into account the impact of contact corrosion, and choose non-corrosive rubber materials, but it still cannot solve the problem of anti-rust during long-term use and corrosion in high-humidity environments

Embodiment 1

[0016] Add raw EPDM rubber in the rubber mixer, the amount is 48.0% of the total mass of anti-rust rubber, press soft, wrap the roll, the roll distance is 6-7mm, the roll temperature is 50-70°C, and then add the anti-rust rubber total Quality 3.5% sodium benzoate, sodium nitrite, benzotriazole, ammonium benzoate and urotropine mixture, wherein sodium benzoate, sodium nitrite, benzotriazole, ammonium benzoate and urotropine (hexamethylene Tetramine) mass ratio is 5: 2: 1: 1: 1, then add anti-rust rubber total mass 0.8% accelerator, 1.2% anti-aging agent butyl (N-phenyl-2-naphthylamine), wrapping , adding 6.0% zinc oxide, 1.0% stearic acid and 6.0% DCP for mixing. When mixing, the roller distance is 6-7mm, and the roller temperature is 50-70°C. Accelerator M and accelerator DM, the mass ratio of accelerator M and accelerator DM is 1:1. Then slowly add 9.5% carbon black (N330) and 24.0% light calcium carbonate of the anti-rust rubber total mass, after the material is added, it i...

Embodiment 2

[0019] Add butadiene rubber raw rubber in the rubber mixing machine, the consumption is 55.0% of the total mass of anti-rust rubber, press softly, cover the roll, then add the mixture of sodium benzoate and sodium nitrite (sodium benzoate and 3.8% of anti-rust rubber total mass) Sodium nitrite mass ratio is 3: 2), 0.9% accelerator (accelerator M and accelerator DM mass ratio are 1: 1) and 0.8% anti-aging agent D, then add antirust rubber gross mass 7.0% oxidation Zinc, 1.2% stearic acid and 7.0% DCP are kneaded evenly and glued. Then slowly add 8.6% carbon black (N330) and 15.7% light calcium carbonate of the total mass of anti-rust rubber. After all the materials are added, ramming is carried out at about 50°C. After the mixing is uniform, it is thinly passed three times, and the tablets are produced. After the sheet is released, it is re-milled, and after the pounding is uniform, it is thinned twice, and the sheet is released, and the anti-rust rubber is obtained.

Embodiment 3

[0022] Anti-rust rubber is composed of raw rubber, anti-rust agent, accelerator, zinc oxide, stearic acid, DCP (dicumyl peroxide), carbon black, anti-aging agent D and light calcium carbonate, by weight percentage, 45 % raw rubber, 3% antirust agent, 0.7% accelerator, 5.0% zinc oxide, 0.8% stearic acid, 5.0% DCP, 9.6% carbon black, 1.0% antiaging agent D, and the balance is light calcium carbonate.

[0023] Wherein: raw rubber is natural rubber; antirust agent is capric acid, dicyclohexylamine, ammonium benzoate, and its mass ratio is 1:1:1; accelerator is accelerator M.

Abstract

The invention relates to a rubber material, and in particular to a rustproof rubber and a manufacturing method thereof. The rustproof rubber comprises by weight 45%-55% of a raw rubber, 3.0%-3.8% of an anti-rust agent, 0.7%-0.9% of an accelerant, 5.0%-7.0% of zinc oxide, 0.8%-1.2% of stearic acid, 5.0%-7.0% of DCP (dicumyl peroxide), 8.6%-9.6% of carbon black, 0.8%-1.2% of an antioxidant D and the balance of light calcium carbonate. When contacting with metal, the rubber provided by the invention can provide excellent rustproof protection to inhibit corrosion of metal and meanwhile avoid possible corrosion of the rubber during contact with the metal.

Description

technical field [0001] The invention relates to a rubber material, in particular to an antirust rubber and a manufacturing method thereof. Background technique [0002] Nowadays, rubber products often need to be used together with metal, for example, rubber plugs are used to seal metal pipe nozzles, rubber pipes are directly connected to metal pipe nozzles, metal parts are inlaid on rubber, and so on. When ordinary rubber products are in contact with or combined with metal products, the rubber has no antirust protection effect on the metal, and the metal material is easy to rust when the humidity is high or the storage time is long, and some additives or additives in the rubber are also harmful to the metal. Certainly corrosive. These situations lead to metal parts being often scrapped and replaced due to corrosion, causing certain economic losses. Especially some weapons and equipment, such as artillery muzzles, are generally sealed with rubber plugs to achieve dustproof ...
