The invention discloses a high surface quality micro-foaming injection molding nylon material. The high surface quality micro-foaming injection molding nylon material includes, by weight, the following components: 40-90 parts of nylon, 5-40 parts of fibers, 5-40 parts of minerals, 1-10 parts of a toughening compatilizer and 0.05-2 parts of an antioxidant. Through the addition of the fibers, the minerals and the toughening compatilizer, nylon forms a physical and chemical micro-crosslinking structure during an extrusion process, so that the melt strength of the nylon material is improved, and uniform and compact micropores are easily obtained. The toughening compatibilizer not only improves the melt strength, but also improves the toughness of a composite material, and is beneficial to obtainment of good mechanical properties. With the addition of the toughening compatilizer, the fibers and the minerals, the foam pore diameter is gradually reduced, the foam pore density is increased, the rigidity and toughness are improved, and the surface appearance of workpieces is greatly improved. The high surface quality micro-foaming injection molding nylon material enables the raw material cost to be saved, and enables the micro-foaming injection molding nylon material with uniform, compact and fine foam pores, the good mechanical properties and high surface appearance to be obtained.
