Problems solved by technology

[0002] With the increase of sulfur content in raw materials for production and processing in the petrochemical industry, the corrosion of equipment is intensified, which seriously affects the normal operation of equipment
In some special environments in other industries, high temperature and severe corrosion seriously restrict the normal operation and production of production equipment. Therefore, the use of general metal and non-metallic materials in key parts of some important equipment cannot solve the corrosion problem of equipment well.
The spare parts are severely corroded, and various toxic and harmful gases are constantly leaking, which often leads to the shutdown of equipment, plant shutdown, production shutdown, and serious equipment accidents and personal safety accidents.
At present, some corrosion-resistant and high-temperature resistant metals are very expensive, and some materials cannot be produced in China

Embodiment Construction

[0037] 1. Material formula: by weight.

[0038] Polytetrafluoroethylene: 70%, POB: 5%, graphite: 20%, molybdenum disulfide: 5%.

[0039] 2. Preparation process:

[0040] (1) Pressing process: After mixing the polytetrafluoroethylene, POB, graphite and molybdenum disulfide in the above formula, the pressing pressure is 37Mpa, the holding time is 90 minutes, and the pressing mold is formed;

[0041] (2) Sintering process: Place the model in the sintering furnace, raise the temperature from room temperature to 327°C and keep it warm for 30 minutes, then continue to raise the temperature from 327°C to 380°C and keep it warm for 150 minutes. Then lower the temperature from 380° C. to 327° C., then keep it warm for 30 minutes, and then continue to cool down to room temperature to obtain the composite engineering plastic of the present invention. The heating rate was 1°C / min, the cooling rate was 1°C / min, and the total sintering time was 12 hours and 57 minutes.

Abstract

The invention provides a novel composite engineering plastic, which is formed by PTFE, POB polyester alloy powders, graphite and molybdenum disulfide through suppression and sintering after being combined based on certain proportions. The composite engineering plastic of the invention has excellent heat-resistant, wear-resistant, anti-aging, corrosion-resistant, self-lubricating and electric-insulating performances, as well as excellent solvent resistance and thermal conductivity and can be widely applied to the high-temperature, high-wearing, strong-corrosion, load-resistance, anti-adhesion and anti-pollution environments of petrochemical enterprises, light industries, machine building, metallurgy, transportation and other departments.

Description

technical field [0001] The invention belongs to the technical field of engineering materials, and relates to a new type of engineering plastic, in particular to an engineering plastic used in environments with corrosion resistance, wear resistance, temperature resistance and self-lubricating properties, that is, a new type of engineering plastic called FPOB. Background technique [0002] With the increase of sulfur content in raw materials for production and processing in the petrochemical industry, the corrosion of equipment is intensified, which seriously affects the normal operation of equipment. In some special environments in other industries, high temperature and severe corrosion seriously restrict the normal operation and production of production equipment. Therefore, the use of general metal and non-metal materials in key parts of some important equipment cannot solve the corrosion problem of equipment well. The spare parts are severely corroded, and various toxic an...
