Embodiment Construction

[0023] The following examples describe the present invention in further detail.

[0024] The novel packing impregnating agent provided by the present invention comprises the following components by weight:

[0025] Graphite milk: 50%;

[0026] PTFE emulsion: 50%;

[0027] Molybdenum disulfide: 3-5%;

[0028] Paraffin: 3-5%;

[0029] High temperature silicone oil: 10-20%.

[0030] Wherein, the graphite milk is an aqueous solution containing 50% ultrafine stone mill, and the tetrafluoro emulsion is an aqueous solution containing 60% polytetrafluoroethylene.

[0031] The method of impregnating the packing with the above-mentioned new impregnating agent is as follows:

[0032] Step 1, fully carry out these five kinds of materials that are 50% graphite milk, 50% tetrafluoroemulsion, 3-5% molybdenum disulfide, 3-5% paraffin and 10-20% high-temperature silicone oil respectively by weight Mix and heat to 100 degrees Celsius, stirring for 10 to 20 minutes;

[0033] Step 2. Subme...

Abstract

The invention relates to a novel packing impregnating agent and a method for impregnating packing by the impregnating agent. The novel packing impregnating agent is characterized by being prepared from the following ingredients in percentage by weight: 50 percent of colloidal graphite, 50 percent of tetrafluoro emulsion, 3 to 5 percent of molybdenum disulfide, 3 to 5 percent of paraffin and 10 to 20 percent of high-temperature silicon oil. Compared with the prior art, the novel packing impregnating agent has the advantage that the novel packing impregnating agent provided by the invention simultaneously has the advantages of the tetrafluoro emulsion, the colloidal graphite, the molybdenum disulfide, the paraffin and the high-temperature silicon oil, and overcomes the defects of a single lubricating agent. When being used for impregnating the packing, the novel packing impregnating agent is permeated to the lubricating agent inside the packing; the fiber compactness is improved; a sealing effect is achieved.

Description

technical field [0001] The invention relates to a novel packing impregnating agent and a method for impregnating packing with the impregnating agent. Background technique [0002] Reducing "running, leaking, leaking" is an eternal topic in the seal industry. Various fiber braided packings are widely used in the sealing of pump valves, but pure crushed fibers such as aramid, acrylic, pre-oxidized silk, cotton yarn The sealing rope cannot be sealed, and generally needs to be impregnated with a lubricant. The commonly used impregnants and their advantages and disadvantages are as follows: [0003] PTFE emulsion: It can improve the compactness of fibers and play a lubricating role, but it is not resistant to temperature and has poor heat dissipation; [0004] Graphite emulsion: It can improve the compactness of the fiber, play a lubricating role, and can also withstand high temperatures, but the fiber will be impregnated with graphite emulsion, and the packing will become hard,...
