Preparation method of flame-retardant antistatic plastic liner plate

Abstract

The invention relates to a preparation method of a flame-retardant antistatic plastic liner plate. The preparation method comprises following steps: 1) polypropylene, high density polyethylene, glass fiber, glass bead, citric acid, talc, calcium carbonate, a silane coupling agent, POE, sodium dodecanesulphonate, decabromodiphenylethane, conductive carbon black, an anti-oxidant, and dicapryl phthalate are taken; 2) the raw materials above are mixed, and a mixture is obtained via stirring; 3) the mixture is delivered into a screw pelletizer for granulation so as to obtain plastic particles; and 4) the plastic particles are subjected to plasticizing using an extruder, are delivered into a mould, and then are subjected to pressing, demoulding, and burr removing so as to obtain the flame-retardant antistatic plastic liner plate. The flame-retardant antistatic plastic liner plate possesses excellent antistatic property and flame resistance, is capable of maintaining relatively high tensile property, is long in service life, is excellent in dry crack resistance, and wet resistance, and is especially suitable for using in severe environments such as environment with mine water and environment with high corrosivity.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a method for preparing a flame-retardant and antistatic plastic liner. Background technique [0002] High-density polyethylene has excellent wear resistance, impact resistance and chemical corrosion resistance. It is widely used as thermoplastic engineering plastics. Among them, plastic lining boards are often used in single-rope winding hoist spindle devices for coal, metallurgy and other mines. , hoisting winch main shaft device drum, and similar machinery that use the drum device to wind the wire rope. Most of the previous single-rope winding hoists used wooden drum linings. Due to the high material selection requirements for wooden drum linings, it was difficult to process rope grooves on site and the service life was short, resulting in frequent replacement of wooden linings.

Problems solved by technology

Most of the previous single-rope winding hoists used wooden drum liners. Due to the high material selection requirements for wooden drum liners, it was difficult to process rope grooves on site and the service life was short, resulting in frequent replacement of wooden liners.

The downtime is long, and the wooden lining rope groove is easy to wear, causing rope biting and skipping, which will seriously affect the safe use of the hoist. Therefore, it is an urgent problem to be solved by using plastic lining boards instead of wooden lining boards. Antistatic and flame retardant properties are required, and a flame retardant and antistatic plastic lining is required to replace the existing wooden lining
