AI Technical Summary

Problems solved by technology

The antistatic agent used in the modification of the chlorinated polyethylene rubber formula is mainly a surface active antistatic agent, which is easy to migrate, decompose and volatilize in the rubber. With the increase of time, the antistatic effect of the rubber will drop sharply, or even become invalid. Antistatic agents have a great influence on the thermal stability of rubber, and it is easy to cause scorching during extrusion

Abstract

The invention discloses flame retardant anti-static chlorinated polyethylene hydraulic hose outer rubber and a preparation method thereof. The flame retardant anti-static chlorinated polyethylene hydraulic hose outer rubber is prepared from the following raw materials in parts by weight: 90-110 parts of chlorinated polyethylene, 10-14 parts of light magnesium oxide; 6-10 parts of magnesium hydroxide, 3-7 parts of petroleum resin; 40-60 parts of carbon black N330, 10-14 parts of acetylene carbon black, 5-9 parts of white carbon black, 3-10 parts of calcium carbonate, 10-15 parts of talcum powder, 15-25 parts of calcined pottery clay, 0.5-2 parts of coupling agents, 35-45 parts of plasticizer, 0.5-2 parts of paraffin wax, 1-3 parts of polyethylene wax and 2-5 parts of vulcanizing agents. According to the flame retardant anti-static chlorinated polyethylene hydraulic hose outer rubber and the preparation method thereof, chlorinated polyethylene rubber is used as main rubber to produce thehydraulic hose outer rubber, so that the production cost is low, the permanent anti-static property is good, scorching is not prone to occurring, and the comprehensive performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of polymer elastomer composite materials, and in particular relates to a flame-retardant and antistatic chlorinated polyethylene hydraulic hose outer glue and a preparation method thereof. Background technique [0002] Hydraulic rubber hoses are widely used in hydraulic engineering machinery, oil drilling, ships, coal mining and other fields. The working conditions are complex. In special environments, due to dynamic stress and friction, the rubber surface is easy to cause charge accumulation. There is a risk of electric shock, fire, and explosion. Therefore, in addition to good aging resistance, ozone resistance, oil resistance, wear resistance, high and low temperature resistance, etc., the outer rubber of the hydraulic hose should also have antistatic function, and the antistatic Ω is required to be 1×10 4 to 1×10 7 . [0003] In response to these requirements, traditionally, the raw materials for the ...
