preparation example Construction
[0024] Another aspect of the present invention provides a kind of preparation method of described antirust rubber, and this preparation method comprises:
[0025] (1) Nitrile rubber is added to the rubber mixing machine, pressed softly, and covered with rolls;
[0026] (2) Then in the rubber mixer, add antirust agent, accelerant and antiaging agent successively and mix evenly, cover roll, then add zincoxide, stearic acid, coumarone resin and mix, ramming evenly;
[0027] (3) Finally, slowly add carbon black for tamping, after tamping evenly, adjust the roller distance, thin the pass, relax the roller distance, discharge the sheet, cool down, and obtain the rubber sheet;
[0028] (4) The rubber sheet is re-milled, covered with rolls, rammed evenly, thinned and then released to obtain anti-rust rubber.
[0029] According to the present invention, preferably, in the step (1), the roll distance is 4-10 mm, the roll temperature is 20-100° C., and the time is 10-40 min.
[0030] ...
Embodiment 1
[0035] This embodiment provides a kind of anti-rust rubber, the consumption of each raw material used is shown in Table 1, and the preparation method is:
[0036] (1) Add nitrile rubber into the rubber mixing machine, press it softly, wrap the roller, the roller distance is 6.5mm, the roller temperature is 60°C, and the time is 25min;
[0037] (2) Then in the rubber mixing machine, add antirust agent, accelerant and antiaging agent and mix uniformly, wrap the roll, then add zincoxide, stearic acid, coumarone resin and mix, ramming evenly, wherein, When mixing, the roller distance is 6.5mm, the roller temperature is 70°C, and the time is 28min;
[0038] (3) Finally, slowly add carbon black for ramming, the roller speed is 17r / min, the speed ratio is 1:1.2, and the roller temperature is 75°C; after the ramming is uniform, adjust the roller distance to 1.2mm, thin pass 4 times, and relax the roller distance to 6.5mm, and cool for 20 hours to obtain rubber sheets;
[0039] (4) ...
Embodiment 2
[0041] The preparation method of this embodiment is the same as that of Example 1, and the consumption of each raw material used is shown in Table 1.

Abstract
The invention discloses antirust rubber and a preparation method thereof. The antirust rubber is prepared from the following raw materials based on the total weight of the raw materials: 5 to 11 weight percent of an antirust agent, 40 to 48 weight percent of nitrile butadiene rubber, 3 to 6 weight percent of an accelerant, 6 to 15 weight percent of zincoxide, 2 to 4 weight percent of stearic acid, 28 to 36 weight percent of carbon black, 0.2 to 0.8 weight percent of an anti-ageing agent and 0.2 to 0.8 weight percent of coumarone resin, wherein the sum of the weight of all the raw materials is100 percent. The antirust rubber disclosed by the invention has good gas-phase antirust performance on metal and a gas-phase corrosion inhibition capability is grade 0; the antirust rubber has no rust and has no contact corrosion on steel and copper.
Description
technical field [0001] The invention belongs to the field of antirust technology, and more specifically relates to an antirust rubber and a preparation method thereof. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metalcorrosion. Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, turning the metal into an oxidized (ion) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. The phenomenon of metal corrosion is very common, and the economic losses caused by metal corrosion are relatively serious ...
