Problems solved by technology

However, the rubber track currently used is prone to aging phenomenon earlier, resulting in insufficient strength of the track in the later use process, unable to meet the requirements of the carrying capacity and service life of construction machinery
[0003] At present, domestic research on the anti-aging performance of rubber tracks mainly improves the aging performance of rubber tracks by adding accelerators, anti-aging agents, plasticizers, diatomaceous earth powder, etc. When rubber tracks are used in the middle and early stages, the aging resistance remains Better, the aging performance is severely reduced in the middle and late stages of use, resulting in insufficient strength of the rubber track, thus reducing the use level of the track to a certain extent, and even having to replace the rubber track in advance

preparation example Construction

[0034] The preparation method of described aging-resistant rubber track is as follows:

[0035] step one:

[0036] Preparation of ingredients: Prepare accelerators AZ and / or BZ, magnesium oxide, anti-scorch agent, silane coupling agent, stearic acid, low-density naphthenic oil and other compounding ingredients, crush and dry, sieve, weigh and put in according to the proportion Stir well in the container.

[0037] Step two:

[0038] Initial mixing: Set the speed ratio of the front and rear rollers of the open mill to 1:1.3, adjust the roll distance of the open mill to 1mm, add raw rubber for mastication, and add the ingredients in step 1 to continue mixing after the plasticization is completed.

[0039] Step three:

[0040] Mixing: Adjust the roller distance of the open mill to 0.8mm, and then mix the rubber after the initial mixing with calcium carbonate, flame retardant, and light stabilizer; after the mixing is completed, add carbon black, The ultra-fine activated clay i...

Abstract

The invention discloses an aging-resistant rubber belt track. Raw materials comprise rubber, accelerant, magnesium oxide, zinc oxide, an anti-aging agent, carbon black, a silane coupling agent kh550,scorch retarder PVI, stearic acid, low-density naphthenic oil, superfine active clay, calcium carbonate, a light stabilizer and a fire retardant, and the aging-resistant rubber belt track is producedthrough initial mixing, mixing, packing and batch-out. Through different rubber components, by adding the anti-aging agent, the scorch retarder, the fire retardant, the carbon black, the superfine active clay, the light stabilizer and the like, the aging-resistant performance and the intensity of the rubber are improved, and the service life of the rubber is prolonged; and the accelerant, the magnesium oxide, the zinc oxide, the silane coupling agent kh550 and the like are adopted for promoting a vulcanization process of the rubber, so that vulcanization of the rubber is fuller.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to an aging-resistant rubber track and a preparation method thereof. Background technique [0002] The rubber track is an endless belt made of rubber and metal or fiber materials. It has the characteristics of no damage to the road surface, small grounding specific pressure, good wet ground passability, small vibration, low noise, fast speed, reduced weight of the whole machine, and good corrosion resistance. Advantages, it has a very wide range of uses in tracked vehicles, and its application proportion in construction machinery, construction machinery, agricultural machinery, and garden machinery continues to increase. However, the rubber track currently used is prone to aging phenomenon earlier, which leads to insufficient strength of the track in the later use process, and cannot meet the requirements of the carrying capacity and service life of construction ...
