Abstract

The invention discloses a powder metallurgy lubricating agent. Polyvinyl isobutyl ether, metallic oxide particles, zinc stearate and fatty acid bisamide are proportionally mixed to be prepared into lubricating agent particles, wherein the lubricating agent particles comprise components in percentages as follows: 33%-37% of polyvinyl isobutyl ether, 13%-15% of metallic oxide particles, 8%-10% of zinc stearate and 45%-48% of fatty acid bisamide; and the lubricating agent particles contain micro wax powder and are covered with paraffin layers. With the adoption of the scheme, the lubricating agent particles of the powder metallurgy lubricating agent contain various lubricating ingredients and are more easily and uniformly distributed in a powder material, the lubricating agent particles are covered with the paraffin layers, and the paraffin layers are broken in the compaction process, so that demoulding can be smoothly performed.

Description

technical field [0001] The invention relates to the field of lubricant formula design used in powder metallurgy, in particular to a powder metallurgy lubricant. Background technique [0002] Powder metallurgy is a processing method that uses metal powder as raw material to make various products by pressing and sintering. The essential advantage of the powder metallurgy parts production process is the rapid prototyping capability of complex parts and high material utilization. [0003] The powder metallurgy process consists of three main steps. First, the main constituent materials are decomposed into powders composed of many fine particles; size of the compact; finally, the compact is sintered. Lubricants are usually added to the raw materials for better fusion of fine particles and release of the green compact. In order to remove the mold for replacement, a variety of lubricants are added to some materials. When the various lubricants are mixed with the material, it is e...
