Abstract
The invention discloses a nylon 6T composite and a preparation method thereof. The nylon 6T composite comprises the following components by weight percent: 27-88% of nylon 6T, 3-9% of ferric oxide, 2-15% of elastomer flexibilizer, 5-60% of glass fiber and 0.5-5% of additive. The glass fiber covered by maleic anhydride grafted ethylene-octene copolymer can react with nylon 6T so as to increase the amount of resin covered on the surface of glass fiber and improve the binding ability of the surface of glass fiber and the resin substrate and all the mechanical properties of the material; as the binding ability of glass fiber and resin is strong, the possibility that glass fiber migrates to the surface in the forming process is reduced and the smooth surface can be obtained; and the method is simple and practical, has low cost and is suitable for large-scale production. Ferric oxide can effectively adsorb the acidic material of the nylon 6T system, thus the thermal-oxidative aging resistance of the system can be increased.
Description
Technical field
The present invention relates to a kind of glass fiber reinforced nylon 6 T material, be specifically related to a kind of good surface and strengthen toughened Nylon 6 T matrix material and preparation method thereof.
Background technology
Nylon 6T material is to use the most general material in the engineering plastics, is widely used in industries such as automobile, building, electronic apparatus and household electrical appliances.Nylon 6T resin can significantly improve its intensity, rigidity and toughness after glass fibre reinforced modified.Plasticizing enhancement nylon 6 T matrix material has good low-temperature flexibility, can be applied to power tool, office furniture, ski boot, cycle hub and other sports equipments etc.Because the requirement that outward appearance is used, these goods often need have slick surface, could be accepted by the human consumer.In addition, the problem of the easy thermo-oxidative ageing of ubiquity.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of with low cost, be applicable to scale of mass production, good surface strengthens toughness reinforcing, the nylon 6T matrix material that thermo oxidative aging property is good.
Another object of the present invention provides the method for the above-mentioned nylon 6T matrix material of preparation.
To achieve these goals, the present invention adopts following technical scheme:
A kind of nylon 6T matrix material, form by the component of following parts by weight:
Nylon 6T 27～88%;
Elastic body toughening agent 2～15%;
Spun glass 5～60%;
Red oxide of iron 3～9%;
Auxiliary agent 0.5～5%.
In above-mentioned nylon 6T matrix material, said elastic body toughening agent is preferably maleic anhydride graft grafted ethylene-octene copolymer.
In above-mentioned nylon 6T matrix material, described spun glass is preferably compatilizer and coats the short glass fiber of handling; Said short fiber spun glass is a non-alkali glass, and the diameter of spun glass is preferably 6～17 microns.
In above-mentioned nylon 6T matrix material, said compatilizer is preferably the ethylene-octene copolymer of maleic anhydride graft.
In above-mentioned nylon 6T matrix material, said auxiliary agent is one or more the mixture in lubricant, oxidation inhibitor, weather resisting agent, the nucleator.The adding of lubricant can form lubricant film at goods and mould product, has both improved release property and has also improved the product surface; The adding of nucleator can the refinement resin matrix crystal grain, improve the bonding force of resin matrix and fiberglass surfacing; The adding of oxidation inhibitor and weather resisting agent can reduce the degraded of material in the life-time service process aging, keeps the excellent surface of product.
The preparation method of above-mentioned nylon 6T matrix material; Adopt the production of melt blending expressing technique; Promptly adopt the forcing machine that a side direction spout is arranged, add nylon 6T resin, elastic body toughening agent and other additive from main spout, the side spout adds short glass fiber; Behind the melt blending, through cooling, air-dry and granulation.
Compared with prior art, the present invention has following beneficial effect:
(1) spun glass of handling through the ethylene-octene copolymer coating of maleic anhydride graft can react with nylon 6T (nylon 6T combines best results in all nylon); Increase the coating of resin, and improved glass surface and the binding ability of nylon matrix and each item mechanical property of material on the surface of spun glass; In the proportional range that limits, has best combination effect;
(2) because the binding ability of spun glass and nylon 6T is strong, spun glass reduces to the chance of surface transport in moulding process, thereby obtains slick surface; The present invention is simple, and is with low cost, is applicable to scale of mass production.
(3) acidic substance that red oxide of iron can active adsorption nylon 6T system, thus help improving the thermo oxidative aging property of system.
