Problems solved by technology

However, because fluorine is a very active element in chemical properties, and some fluorides are harmful to the human body; at the same time, cast stone materials such as diabase or shale itself contain oxides of titanium and phosphorus, so adding titanium and phosphorus to it Whether the oxide can achieve the purpose of modification remains to be further explored

Embodiment 1

[0021] Take 80Kg of cast stone powder, 13Kg of polypropylene, and 7Kg of graphite powder, and then put each material into a container and stir well. After stirring evenly, put it into a mold with the same shape as the idler, and heat it to about 160°C. After plasticizing for a certain period of time, it is naturally cooled and demoulded to be the finished product.

Embodiment 2

[0023] Take 70Kg of cast stone powder, 15Kg of polypropylene, and 15Kg of carbon black, and then put all the materials into a container and stir them well. After they are evenly stirred, put them into a mold with the same shape as the idler roller, and heat them to about 140°C. After plasticizing for a certain period of time, it is naturally cooled and demoulded to be the finished product.

Abstract

A composition for preparing the antistatic and elastic supporting roller is prepared from cast stone powder, crystalline polymer and antistatic agent. Said supporting roller is made up of said composition through mixing, stirring, filling the mixture in mould, plasticizing at 130-160 deg.C, pressing, natural cooling and demoulding. It is suitable for belt conveyer.

Description

Technical field: [0001] The invention relates to a composition for preparing idler rollers, in particular to a composition for preparing idler rollers for conveyors and a method for preparing idler rollers. Background technique: [0002] The idler roller is the main part used on the conveyor, especially the belt conveyor, which is widely used in various fields such as mines, coal mining, and construction. Traditional idlers are usually made of metal materials such as alloy steel or cast steel. During the relative movement between the metal material and the tape, the constant friction between each other can easily generate static electricity, and the equipment that is prone to static electricity is not suitable for use in deep well coal mining and other occasions, because the static sparks generated can easily cause gas Explosion; In addition, due to the heavy weight of the metal roller, the conveyor has a large reactive power loss, and its corrosion resistance is relatively...
