Embodiment

[0016] A kind of outsole rubber for rubber-faced insulating boots that is not easy to scorch, calculated by parts by weight, comprising:

[0017] 1# smoked sheet rubber 100, sulfur 0.8, accelerator M 0.5, accelerator DM 1.1, accelerator TMTD 0.8, zinc oxide 5, stearic acid 1.5, antioxidant D 1.5, calcium carbonate 60, clay 60, pine tar 9.5, Montan wax 1.0, vaseline 2, paraffin wax 1, zinc stearate 1, oil soluble black 3.9, salicylic acid 0.3.

[0018] Preparation:

[0019] Add the formula amount of natural rubber into the internal mixer and mix completely, then add zinc stearate, oil soluble black, accelerator and mix completely in the open mill, then add the formula amount of salicylic acid, anti-aging agent and accelerator The plasticizer continues to mix completely, and finally adds sulfur and mixes completely.

Abstract

The invention discloses an outsole rubber for insulating boots with a rubber surface that is not easy to scorch, which is characterized in that, calculated in parts by weight, it comprises: natural rubber 100, sulfur 0.7-0.9, accelerator M 0.4-0.6, accelerator DM 1.0 ‑1.2, accelerator TMTD 0.7‑0.9, zinc oxide 4‑6, stearic acid 1.4‑1.6, antioxidant D 1.4‑1.6, calcium carbonate 60, clay 60, pine tar 9‑10, montan wax 0.8‑1.2, Vaseline 1‑3, paraffin 0.8‑1.2, zinc stearate 0.9‑1.1, oil soluble black 3.8‑4.0, salicylic acid 0.2‑0.4. The outsole rubber for insulating boots produced with this formula has good insulation performance and low cost, can adapt to the operating environment of electricians, and is suitable for protection in electrical work; it can greatly improve the safety of rubber processing.

Description

technical field [0001] The invention relates to the field of rubber material preparation, and relates to a formula of outsole rubber for shoes, in particular to an outsole rubber for insulating boots with a rubber surface that is not easy to burn. Background technique [0002] For shoes made of ordinary rubber materials, the outsole rubber is usually natural rubber plus synthetic rubber, which has a wide range of applications and low cost. However, due to the low dielectric properties of some synthetic rubbers, the insulation of the outsole rubber is poor. Most of the accelerators and anti-aging agents commonly used in the chemical industry contain sulfur or nitrogen. Even if the amount used is very small, it will affect the electrical properties. The rubber containing the polar accelerators and anti-aging agents has high water absorption and the dielectric properties will be more obvious. Decrease, the commonly used filler and reinforcing agent carbon black will lead to a d...
