Problems solved by technology

However, such materials are often related to the nylon matrix. Once the matrix of the reinforced nylon product changes, the general production needs to be adapted through the adjustment of the elastomer formula. The operation workload is large, the efficiency is low, and the cost is high.

Abstract

The invention relates to a polyamide composite material with good touch feeling and easy encapsulation and a preparation method thereof. The material comprises the following components in parts by weight: 25-75 parts of PA6 resin; 15-50 parts of glass fiber; 5-15 parts of styrene copolymer ; 2-8 parts of compatibilizer; 3-10 parts of polar modifier; 0.2-0.5 parts of antioxidant; Graft copolymer; when preparing, weigh other components except glass fiber according to the mass fraction and mix them in a high-speed mixer, then put them into the main feeding port of the twin-screw extruder, and the glass fiber is fed from the side feeding port Add, extrude and granulate. The polyamide composite material with good touch and easy encapsulation obtained in the present invention has the characteristics of good surface touch, wear resistance, easy encapsulation, etc., and can be widely used in fields such as electric tools, sports equipment, electronic appliances and the like that require encapsulation injection molding.

Description

technical field [0001] The invention relates to the technical field of polyamide materials, in particular to a polyamide composite material with good tactility and easy encapsulation and a preparation method thereof. Background technique [0002] Polyamide has ideal chemical resistance, processability and heat resistance, and is the first of the five engineering plastics, among which PA66 and PA6 are the most widely used. Unmodified polyamide has low strength, high water absorption, and poor dimensional stability. Adding a certain amount of inorganic reinforcing materials can significantly improve these properties. The most common is that the addition of glass fiber can significantly improve the mechanical properties of nylon materials. Tools and other engineering components are widely used, but due to their high hardness and rough surface, when they are held and used for a long time, they will cause discomfort due to contact and friction. At present, the more common method ...
