Abstract

The method discloses a method for making an oil-resistivity red cable sheath by double rollers, which belongs to the technical field of cable line, the method comprises the following steps: 1)preparing the raw materials for standby; 2) kneading; 3) mixing, placing the powder in a mixing chamber; 4) milling by two rollers, discharging to a two-roller mill, under steam pressure being 0.4-0.5 MPa, heating to the roll temperature at 160-170 DEG C until the materials are completely and uniformly plasticized, and obtaining sheet with thickness being 3 mm as a material sheet; and 5) cooling, granulating and packaging. The method has the advantages of simple operation, work efficiency of milling by two rollers is high, product quality is good, through combinations of various raw materials, heat-resisting and oil-resisting performances of the cable sheath can be ensured, no lead and cadmium is generated in the formula, heavy metal poisoning can be prevented when the cable sheath is heated, and the cable sheath has the advantages of environment protection and durability.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a method for making oil-resistant red cable sheaths with double rollers. Background technique [0002] The global production of plastics used for wires and cables has grown rapidly in recent years. At the same time, fire accidents caused by burning plastics have increasingly become a major social problem. Cable sheaths are widely used in the cable manufacturing process. Traditional cable sheath preparation methods are complex, and the prepared cable sheaths are flammable and release a large amount of poisonous gas when burned, which cannot meet the requirements of environmental protection. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a method for making oil-resistant red cable sheaths with two rollers, which is not only environmentally friendly and convenient, but also the prepared cable sheaths are n...
