Description
Technical Field
The invention relates to the technical field of crawler belt manufacturing, in particular to a wheel side rubber composition for a crawler belt, a mixing method, application and a high-cost performance crawler belt.
Background
The caterpillar is an annular rubber belt made of rubber and metal or fiber composite materials. The wheel side rubber of the crawler is the inner side rubber of the rubber crawler, contacts with the rotating wheel during walking, is repeatedly rolled by a mechanical gear during operation, contacts with the open air environment, needs higher elasticity and fatigue resistance, and is critical to the whole crawler body as a critical component of the crawler.
The cracking carbon black is a low-surface-activity reinforcing filler formed by high-temperature cracking or oil cracking or natural gas cracking of waste rubber products, particularly waste tires, belongs to resource recycling, is beneficial to environmental protection and has relatively low cost. CN 114213721A discloses a truck radial tire tread, which uses multiple active points of graphene to compensate for the loss of surface activity of the cracked carbon black, but the graphene is relatively expensive. There are rarely reports of the presence of cracked carbon black in the related patents of crawler side gums.
The carbon black particles have nonuniform surface activity, few active points and a series of adsorption points with different energies. The micro-morphology and physical structure characteristics of the carbon black are researched by adopting TEM, AFM and STM, and the active groups of the carbon black are derived from the edge aromatic ring structure of carbon black microcrystals, so that the aromatic ring energy is high and can easily act with rubber molecular chains to reinforce the rubber; the same applies to the cracking of carbon black. The present application aims at raising the cost performance of crawler belt via using cracked carbon black and searching one kind of relatively low cost material to react with low surface activity cracked carbon black stuffing to link more high energy aromatic rings and raise the adsorption of cracked carbon black to rubber chain.

The wheel side rubber adopting the rubber composition is beneficial to reasonable and effective recycling (green development) of resources and reduction of track cost (economic development) on the premise of meeting basic performances.
In order to achieve the above purpose, the present invention adopts the following technical scheme:

Preferably, the composition is prepared by mixing the following raw materials in parts by weight based on 100 parts by weight of the rubber component:
2.0 to 5.0phr of biobased material.
Preferably, the carbon black is one or both of N330 and N375; the cracking carbon black is waste tyre cracking carbon black.
Preferably, the raw materials of the composition further comprise a protective wax, an anti-aging agent, a softening agent, an activator, a vulcanizing agent and an accelerator.

Furthermore, the invention also discloses a mixing method of the tread pattern side rubber composition for the track, which is used for plasticating raw rubber and a small amount of carbon black to reduce the viscosity and ensure better phase dispersion; adding the rest carbon black, the cracking carbon black and the bio-based material, and adding the softener and other ingredients after the carbon black is basically dispersed in the rubber.
As a specific embodiment, the method comprises the steps of:
and (3) first stage plasticating: adding raw rubber and 1/3 carbon black, pressing the lump for 30-40sec, cleaning the lifted lump, pressing the lump for mixing, discharging rubber at 140-150 ℃, and thinning and discharging sheets on an open mill; the rotating speed is 45r/min in the plasticating process;
and (3) mixing in a second stage: adding a section of plastisol, the rest 2/3 of carbon black, the cracking carbon black and the biological base material, pressing and mixing to 120-130 ℃, then adding a softener and the rest compounding agents, pressing the lump for 25-35sec, lifting the lump and cleaning, pressing the lump and mixing to 150-160 ℃ and discharging the rubber, and thinning and discharging the sheet on an open mill; the rotating speed in the mixing process is 45-40-40r/min;
and (3) mixing in a third section: adding two-stage mixed rubber and final-refining fine materials, pressing the mixture for 30-40sec, cleaning the lifted mixture, then pressing the mixture for 25-35sec, cleaning the lifted mixture, then pressing the mixture for mixing to 100-110 ℃ for rubber discharge, and thinning and discharging sheets on an open mill; the rotating speed in the mixing process is 25-20-20r/min;
the interval processing time of each section of sizing material is not less than 4 hours, so that the sizing material is ensured to be fully loosened and dispersed.
Furthermore, the invention also discloses application of the tread pattern side rubber composition for the track in preparation of the track with high cost performance.
Furthermore, the invention also discloses a high-cost performance crawler belt, and the side rubber of the crawler belt is prepared by vulcanizing the wheel side rubber composition for the crawler belt.
The beneficial technical effects of the invention are as follows: the cost of cracking the carbon black is low, and the carbon emission is reduced due to the recycling of waste rubber products; the bio-based material belongs to renewable natural resources, lignin is one of the renewable resources with the most abundant content in the nature, contains abundant aromatic rings and phenolic hydroxyl groups, and the lignin phenolic resin is lignin synthesis polymer, so that the cost of the bio-based lignin/lignin phenolic resin is lower. The crawler wheel side rubber can effectively reduce the cost by using the cracking carbon black, and simultaneously, the hydroxyl of the bio-based lignin/lignin phenolic resin and the active oxygen-containing group on the surface of the cracking carbon black/carbon black are used for reinforcing the rubber by linking the aromatic ring so as to improve the effect of the cracking carbon black/carbon black and diene rubber molecular chains. On the premise of meeting basic performance, the wheel side adhesive is beneficial to reasonable and effective recycling (green development) and reduction of track cost (economic development).
