Shoe upper glue used for insulating boots

Abstract

The invention discloses a vamp glue for insulating shoes, 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 D 0.3-0.5, accelerator DM 0.2‑0.4, accelerator TMTD 0.7‑0.9, zinc oxide 1.9‑2.1, stearic acid 1.4‑1.6, antioxidant A 0.4‑0.6, antioxidant D 0.8‑1.2, calcium carbonate 67, talcum powder 20, montan wax 0.8 ‑1.2, paraffin 1.4‑1.6, zinc stearate 1.9‑2.1, oil soluble black 1.2‑1.4. Use natural rubber to improve the dielectric properties; reduce the amount of sulfur, and replace part of the amount of sulfur with the accelerator TMTD; use calcium carbonate with low water absorption and talcum powder in combination; the insulation performance of the insulating boots rubber produced with this formula is relatively low. Good, the cost is low, it can adapt to the operating environment of electricians, and it is suitable for the protection of electric work.

Description

technical field [0001] The invention relates to the field of rubber material preparation, and relates to a formula for shoe upper glue, in particular to a shoe upper glue for insulating shoes. Background technique [0002] For shoes made of ordinary rubber materials, the upper 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 rubber, the insulation of the upper 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. The commonly used filler and reinforcing agent carbon black will cause the electrical properties of rubber to decrease. Therefore, the commonly us...
