Problems solved by technology

[0002] Ordinary rubber materials cannot work in acid-base, salt solution and other chemicals for a long time. Ordinary rubber materials will cause corrosion when they contact with acid-base, salt solution and chemicals, causing rubber swelling, rubber molecular breakage, depolymerization and compounding agent breakdown. Decomposition, dissolution and other phenomena lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., and cracks are generated by the attack of ozone, so that the corrosion completely loses its working ability.
[0003] In the prior art, rubbers with strong acid and alkali resistance include nitrile rubber, butyl rubber, chlorosulfonated polyethylene, fluorine rubber, etc., but they are expensive, and large-scale applications will lead to increased product costs, which are not suitable for acid and alkali resistant rubber.

Embodiment 1

[0032] In the present embodiment, a kind of acid and alkali resistant rubber sole is prepared from the raw materials of the following components by weight:

[0033]

[0034]

[0035] Integrated rubber is a pilot product of PetroChina Lanzhou Petrochemical Company. The mass fraction of styrene is 25%, the mass fraction of isoprene is 40%, and the mass fraction of butadiene is 35%. Among them, 1,2-structure butadiene in butadiene Diene mass fraction is 78%;

[0036] Put the rubber materials of the component materials except insoluble sulfur, vulcanization accelerator TMTD, and vulcanization accelerator NS into the banbury mixer, deglue at 118°C, leave at room temperature for 24 hours, and then mix on the double-roller open mill. Add accurately weighed insoluble sulfur and a special vulcanization accelerator. After mixing evenly, the sheet is uniformly released. Finally, the material is cut into the shape of a shoe sole and put into a rubber shoe mold for vulcanization. The...

Embodiment 2

[0038] In the present embodiment, the preparation method of a kind of acid and alkali resistant rubber sole is basically the same as the preparation method in Example 1, the difference is:

[0039] 150,210 parts of styrene-butadiene rubber and 1108 parts of C9 petroleum resin PR in embodiment 2.

Embodiment 3

[0041] In the present embodiment, the preparation method of a kind of acid and alkali resistant rubber sole is basically the same as the preparation method in Example 1, the difference is:

[0042] In Example 3, 150,220 parts of styrene-butadiene rubber, 20 parts of white carbon black, 11,012 parts of C9 petroleum resin, and 692 parts of coupling agent Si.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, in particular to an acid and alkali-resistant rubber sole and a preparation method thereof. Background technique [0002] Ordinary rubber materials cannot work in acid-base, salt solution and other chemicals for a long time. Ordinary rubber materials will cause corrosion when they contact with acid-base, salt solution and chemicals, causing rubber swelling, rubber molecular breakage, depolymerization and compounding agent breakdown. Decomposition, dissolution and other phenomena lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., cracked by ozone attack, and even corroded completely loses its working ability. [0003] In the prior art, rubbers with strong acid and alkali resistance include nitrile rubber, butyl rubber, chlorosulfonated polyethylene, fluori...
