Abstract
The present invention provides one kind of nylon composition for skeleton of automobile steering wheel and its production process. The nylon composition is prepared through mixing nylon-6 slice, inorganic mineral, solvent, antioxidant and coupling agent in a high speed mixer; mixing with glass fiber and pelletizing in a screw extruder; cooling and stoving. The nylon composition is made into skeleton of automobile steering wheel through injection molding and foaming. The steering wheel skeleton of the nylon composition has high stability, high strength, low bounce, light weight and other advantages.
Description
Technical field
The present invention discloses a kind of nylon composite and manufacture method that is used for automobile steering wheel framework, relates to the Manufacturing Technology for Automotive Parts field.
Background technology
The existing steering wheel skeleton mostly is metallic substance and makes, the spoke formation that turns to hub and connect coil that circular coil, insertion steering shaft are arranged, adopt welding or casting technique moulding, its deficiency be in: total quality is heavier, the bounce that produces during impact is big, temperature sensitivity is strong, and handling property is poor, and the rate of recovery is little.
Summary of the invention
The invention provides a kind of nylon composite that is used for automobile steering wheel framework, replace metallic substance manufacturing direction dish skeleton.
The present invention also provides the bearing circle made from above-mentioned material, and the quality that has solved the existence of metallic framework bearing circle is heavy, shortcomings such as feel difference.
Nylon composite of the present invention contains following materials of weight proportions:
Nylon 6 slice 50～70, inorganic mineral 8～20, phase solvent 1～12,
Antioxidant 0.1～0.6, coupling agent 0.1～0.8, glass fibre 20～30.
Technical solution of the present invention is as follows: add 8～20% inorganic mineral, 1～12% phase solvent, 0.1～0.6% antioxidant, 0.1～0.8% coupling agent in high-speed mixer and mixing discharging in 2～5 minutes in 50～70% nylon 6 slice, glass fibre with 20～30% adds, together put into screw rod machine extruding pelletization, cooling, pelletizing, dry the nylon composite material;
Described inorganic mineral is selected from talcum powder or lime carbonate;
Described phase solvent is selected from EPDM grafting or maleic anhydride graft compatilizer
Described antioxidant is selected from 2777 or H10 or 1010;
Described coupling agent is selected from silane resin acceptor kh-550 or KH-560.
Frame of handwheel is made in above-mentioned nylon composite injection moulding, can be made into two kinds of structures:
One, 2/5 part of coil is carried out the ABS injection moulding, and 3/5 part of all the other coils is carried out the PU foaming and formed from skinning.The mahogany transfer printing is partly imitated in the ABS injection moulding, and all the other are from skinning part outsourcing corium;
Two, coil all foams and forms from skinning, but and deep processing, all outsourcing corium.
Above technical parameter is respectively:
1. Shooting Technique: adopt modified ABS.
Temperature is 195～210 ℃;
Pressure is 65%～80%;
Injection time was 6 seconds.
2. foam process: adopt the polyurethane PU foamed material.
