Embodiment

[0014] A kind of shoe upper glue for sticking legal oil resistant boots that can prevent scorching, calculated in parts by weight, including

[0015] Styrene butadiene rubber 70, nitrile rubber 30, chloroprene rubber 1.5, sulfur 0.45, accelerator M 0.15, zinc oxide 5, magnesium oxide 4, stearic acid 1.5, antioxidant D 2.0, calcium carbonate 45, pine tar 3, two Butyl ester 15, black ointment 4, carbon black 20, anti-scorching agent YG-10.3, anti-scorching agent PVI 0.3.

[0016] Preparation:

[0017] Add the formula amount of rubber into the internal mixer and mix it completely, then add stearic acid, carbon black, and accelerator to mix in the open mixer, then add the formula amount of antioxidant, plasticizer, and filler to continue mixing The refining is complete, and finally sulfur is added and the mixing is complete.

Abstract

The invention discloses a vamp glue for laminating oil-resistant boots capable of preventing scorching, which comprises styrene-butadiene rubber 60-80, nitrile-butadiene rubber 40-20, neoprene rubber 1.5, sulfur 0.4-0.5, Accelerator M 0.1‑0.2, Zinc Oxide 5, Magnesium Oxide 4, Stearic Acid 1.5, Antiaging Agent D 1.5‑2.5, Calcium Carbonate 40‑50, Pine Tar 2‑5, Dibutyl Ester 15, Black Ointment 2‑5 , carbon black 20, anti-scorch agent YG-1 0.2-0.4, anti-scorch agent PVI 0.1-0.5. The use of styrene-butadiene rubber in combination with nitrile and neoprene has good oil resistance; the amount of filler calcium carbonate is appropriately increased to help anti-swelling. The shoe upper rubber produced with this formula has good oil resistance and low cost, can adapt to the oil-resistant operating environment, is suitable for protection in oil-resistant operations, and is not prone to scorching during processing, which can greatly improve the safety of rubber processing .

Description

Technical field [0001] The invention relates to the field of rubber shoes manufacturing, and relates to a shoe upper rubber formula for boots, in particular to a shoe upper rubber that can prevent scorching and is used for oil-resistant boots. Background technique [0002] For shoes made of ordinary rubber materials, the upper rubber is usually natural rubber plus synthetic rubber, which is widely used and low in cost. However, due to the insufficient solubility parameters of natural rubber and oil media, the upper rubber has poor oil resistance. Therefore, the commonly used shoe upper rubber formulations cannot be used for protective boots that come in contact with oil. [0003] Scorch is a phenomenon of early vulcanization of rubber compounds. The reasons for scorch are: improper combination, such as excessive amount of vulcanizing agent and accelerator; improper operation, such as high roller temperature, premature addition of sulfur, or after adding vulcanizing agent The mixin...
