Abstract
The present invention discloses a high performance environment protection oil-free lubrication material formula and a high performance environment protection oil-free lubrication composite plate preparation process. The formula comprises, by weight, 6-12% of polyimide, 6-12% of aramid fibers, 3-6% of arolnatic polyester, 6-12% of molybdenum disulfide, 6-12% of tin bronze, and the balance of polytetrafluoroethylene. The oil-free lubrication composite plate preparation process comprises: plating copper on a substrate, sintering lead-free spherical bronze powder on the substrate, preparing a powder material, carrying out high speed material mixing, carrying out wet mixing, carrying out paving rolling, drying, sintering, and carrying out fine rolling to prepare the finished product plate. According to the present invention, complementary characteristics of various raw material individuals after mutual fusion are provided, the intensive advantages of the raw material are well provided, friction, wear resistance, corrosion resistance, fatigue resistance, impact resistance, compressive strength, carrying capacity, thermal stability and other physical properties of the material are superior to friction, wear resistance, corrosion resistance, fatigue resistance, impact resistance, compressive strength, carrying capacity, thermal stability and other physical properties of the surface wear resistance layer in the lead-containing oil-free bearing, and a high performance environment protection oil-free lubrication effect is provided.
Description
technical field [0001] The invention relates to a formula of a wear-resistant material, and a manufacturing process of a high-performance, environment-friendly, oil-free lubricated composite plate produced by using the formula, which is composed of three layers of steel plate, copper powder and wear-resistant material. Background technique [0002] In the 1970s, sliding bearings were made of steel plate, copper powder, and plastic three-layer composite oil-free lubricating material, which were used in textile, printing, hydraulic and other industries. In the later practice, the product application fields became wider and wider, and more and more product defects were discovered. The production enterprises improved the formula and manufacturing process of the bearings. [0003] The most mature formula of the surface wear-resistant layer in the three-layer composite material is 45% polytetrafluoroethylene (PTFE) plus 55% lead (Pb). The product has good performance and has been ...
