Embodiment 1

[0020] Add 3% polyethylene wax and 20% polytetrafluoroethylene modified polyethylene wax into the mixing tank and heat to 130 °C until all the materials are melted and stir for 10 minutes, then add 4.5% 2,6-to-two Tert-butyl p-cresol, 25% white oil, 3% sodium petroleum sulfonate, 10% fumed silica, 0.1% polysiloxane, stirred and dispersed for 10 minutes, then put the prepared raw materials into the soaking tank, and put The polyester fiber non-woven fabric is soaked in the soaking tank for 3 minutes and then transported to the cooling drum. After cooling to normal temperature, it is immersed in the slitting and rewinding machine, slitting and winding according to the required length and width, and then packed into the warehouse.

Embodiment 2

[0022] Add 70% polyethylene wax and 5% polytetrafluoroethylene modified polyethylene wax into the mixing tank and heat to 180 °C until all the materials are melted and stir for 1 minute, then add 0.5% 2,6-to-two Tert-butyl p-cresol, 5% white oil, 2% sodium petroleum sulfonate, 1.5% fumed silica, 0.5% polysiloxane, stirred and dispersed for 50 minutes, then put the prepared raw materials into the immersion tank, and put The polyester fiber non-woven fabric is soaked in the soaking tank for 20 minutes and then transported to the cooling drum. After cooling to normal temperature, it is immersed in the slitting and rewinding machine, slitting and winding according to the required length and width, and then packed into the warehouse.

Embodiment 3

[0024] Add 70% polyethylene wax and 10% polytetrafluoroethylene modified polyethylene wax into the mixing tank and heat to 150°C until all the materials are melted and stir for 5 minutes, then add 2% 2,6-to-two Tert-butyl p-cresol, 15% white oil, 2% sodium petroleum sulfonate, 6% fumed silica, 0.3% polysiloxane, stirred and dispersed for 30 minutes, then put the prepared raw materials into the soaking tank, and put The polyester fiber non-woven fabric is soaked in the soaking tank for 10 minutes and then transported to the cooling drum. After cooling to normal temperature, it is immersed in the slitting and rewinding machine. It is cut and rewound according to the required length and width, and then packed into the warehouse.

Abstract

A high-temperature resistant wax anticorrosion material is disclosed. The anticorrosion material is prepared from, by mass, 3-70% of polyethylene wax, 5-20% of polytetrafluoroethylene modified polyethylene wax, 0.5-4.5% of 2,6-bis(1,1-dimethylethyl)-4-methylphenol, 5-25% of white oil, 2-3% of petroleum sodium sulfonate, 1.5-10% of fumed silica, and 0.1-0.5% of polysiloxane. The anticorrosion material can overcome the problem that other flexible anticorrosion materials cannot resist high temperatures, and overcomes a problem that petrolatum type anticorrosion materials are prone to component loss and volatilization. The process and operation are simple. The anticorrosion material is prone to industrial production.

Description

technical field [0001] The invention relates to the field of metal anticorrosion, in particular to a high-temperature-resistant refined wax anticorrosion material. Background technique [0002] Most anti-corrosion materials belong to the category of normal temperature anti-corrosion, and metal equipment in chemical industry, metallurgy, electric power and other industries are under the test of high temperature all the time, and there are generally serious corrosion problems in high temperature environment. For room temperature corrosion, people have done a lot of work and achieved remarkable results. However, for high-temperature (above 100°C) corrosive environments, such as high-temperature pipelines in petrochemical plants and facilities with harsh corrosive environments such as acids, alkalis, and salts, and steam pipelines such as boilers in thermal power plants operate in high-temperature and humid environments for a long time. Under such harsh conditions, the service ...
