Embodiment Construction

[0008] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the examples.

[0009] A polytetrafluoroethylene synthetic material, which contains polytetrafluoroethylene powder, crystal glass fiber, lead powder, polytetrafluoroethylene synthetic emulsion, and liquid wear-resistant material, with a weight ratio of 2.7:1.5:2:1.25:4.5 .

[0010] PTFE synthetic emulsion is made by mixing 70% PTFE emulsion and 30% graphite powder. Take out the polytetrafluoroethylene emulsion and graphite powder in a ratio of 7:3, and mix them at a temperature below 14°C for 10 minutes, and then cool them at a temperature below 5°C for more than 12 hours. Higher viscosity.

[0011] The liquid wear-resistant material contains 0.5%~1% ammonia by weight, 3.5%~4.5% molybdenum disulfide, 2%~3% nodular ink molecules, 1%~1.5% nickel, and the rest is copper, ...

Abstract

The invention discloses a polytetrafluoroethylene synthesis material. The polytetrafluoroethylene synthesis material contains polytetrafluoroethylene powder, crystallized glass fibers, lead powder, a polytetrafluoroethylene synthesis emulsion and a liquid wear-resistant material according to a weight ratio of 2.7:1.5:2:1.25:4.5; and the polytetrafluoroethylene synthesis emulsion is prepared by mixing 70% of a polytetrafluoroethylene emulsion with 30% of graphite powder. The polytetrafluoroethylene synthesis material has the advantages of improvement of the substance uniformity, reduction of the wall thickness tolerance range, and improvement of the quality and stability of products.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a polytetrafluoroethylene composite material. Background technique [0002] Steel-based copper-plastic self-lubricating material, mainly steel plate as the substrate, high-temperature sintered copper powder on the steel plate, after the copper powder is sintered and cooled, a layer of polytetrafluoroethylene synthetic powder is compounded on the copper powder, and then low-temperature sintered . When PTFE synthetic powder is compounded, it will cause uneven texture and uneven wall thickness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polytetrafluoroethylene composite material that can make the material distribution uniform and the wall thickness uniform when composited. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [000...
