Technical Field

Background

The polyamide resin is a polycondensation type high molecular compound having a CONH structure in the molecule, and is usually obtained by polycondensation of a dibasic acid and a diamine. The most prominent advantage of polyamide resins is the extremely narrow range of softening points, unlike other thermoplastic resins, which have a gradual curing or softening process, which causes rapid curing at temperatures slightly below the melting point. The polyamide resin has good chemical resistance and can resist acid, alkali, vegetable oil, mineral oil and the like. Because the molecule of the adhesive has polar groups such as amino, carbonyl, amide and the like, the adhesive has good gluing performance on plastics such as wood, pottery, paper, cloth, brass, aluminum, phenolic resin, polyester resin, polyethylene and the like.

The polyamide resin has good comprehensive properties including mechanical property, heat resistance, abrasion resistance, chemical resistance and self-lubricity, has low friction coefficient and certain flame retardance, is easy to process, is suitable for being filled with glass fiber and other fillers for reinforcing and modifying, improves the performance and expands the application range.

Because the polyamide resin has the advantages of no toxicity, light weight, excellent mechanical strength, wear resistance and better corrosion resistance, the polyamide resin is widely used for replacing metals such as copper and the like to manufacture bearings, gears, pump blades and other parts in the industries such as machinery, chemical engineering, instruments, automobiles and the like.

The invention provides a preparation process of a polyamide resin composite material for a robot in view of the special high-quality performance of polyamide resin, and the preparation process meets the use requirement of flexible work of the robot.
