Vamp rubber for rubber-vamp insulating boots

Abstract

The invention discloses a shoe upper glue for rubber-faced insulating boots, 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 Agent 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, talcum powder 87, 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 use talcum powder with low water absorption; the upper rubber for insulating boots produced by this formula has better insulation performance and lower cost, and can adapt to the operating environment of electricians. Protection from electrical work.

Description

technical field [0001] The invention relates to the field of rubber material preparation, and relates to a formula of upper glue for shoes, in particular to a rubber upper glue for insulating boots with rubber surface. 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. ...

[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. Decrease, the commonly used filler and reinforcing agent carbon black will cause the electrical properties of the rubber to decline, therefore, the commonly used upper rubber formulations cannot be used for protection against electrical work
