Abstract
The invention discloses a high-intensity injection moulded plastic part material which comprises a mixture of a polyamide material and a modifying agent, wherein the polyamide material is polyamide 66, and the modifying agent comprises a glass agent. The high-intensity injection moulded plastic part material is used for manufacturing a gear or cam part, and has the characteristics of high strength and impaction resistance.
Description
Technical field
The present invention has about a kind of injectable plastic material, is particularly applied in the high-strength injection moulding material on auto parts.
Background technology
Along with the change of technical development and people's idea, in automobile component, there are many non-metallic components.Be wherein plastics part as the leading material of non-metallic component, it is easy to process, easy for installation, uses lightly, therefore more and more obtains the favor of automobile industry, and using plastics part is its inevitable requirement of development of automobile from now on.
In plastic cement products manufacturing processed, forming plastic pieces is one of important content very wherein.Forming plastic pieces is the process of the plastics of various forms (powder, pellet, melt and dispersion) being made to goods or the blank of desired shape.
Typical injection molding system comprises an injecting unit, a clamp assembly and a die assembly except other business.In injecting unit, starting material (for example PET pellet and analogue) pass through a funnel by feeding, and are heated by material tube heater, then are expelled in mould by nozzle.
But due to properties of materials relation, the auto parts that current injectable plastic material forms lack certain physical strength, can not directly transmit power and energy, therefore be normally used for common ornamental member, and can not be used in the parts with certain physical strength that bear load, such as gear, rotating shaft etc.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of high strength injection moulding part material, described material comprises: the mixture of polyamide material and properties-correcting agent composition, wherein: described polyamide material is polyamide 66, and described properties-correcting agent comprises vitrifying agent, and described material is used to manufacture gear or cam parts.
It is main raw that material in the present invention adopts polyamide 66, and it has semi-crystalline-crystalline material characteristic, and coordinates glass modifier, and mechanical property is improved, and particularly has higher intensity, and is manufactured into the parts such as gear cam.
Embodiment
The invention provides a kind of novel moulding material, particularly there is high-intensity moulding material, for example, substitute the injection made gear part of automobile metal part.
The invention provides a kind of high strength injection moulding part material for this reason, described material comprises: the mixture of polyamide material and properties-correcting agent composition, wherein: described polyamide material is polyamide 66, and described properties-correcting agent comprises vitrifying agent, and described material is used to manufacture gear or cam parts.
In an embodiment of the present invention, polyamide 66 (PA66) has higher fusing point in polyamide material, and it is a kind of semi-crystalline-crystalline material, therefore has stronger mechanical property, and PA66 also can keep stronger strength and stiffness at comparatively high temps.
Meanwhile, in order to improve the mechanical characteristics of PA66, added properties-correcting agent, preferably glass is as additive.
Therefore, it is main raw that material in the present invention adopts polyamide 66, and it has semi-crystalline-crystalline material characteristic, and coordinates glass modifier, and mechanical property is improved, and particularly has higher intensity, and is manufactured into the parts such as gear cam.
As improvement of the present invention, described material also comprises the mixture of polycarbonate and polybutylene terephthalate.It can improve toughness and oilness, is more conducive to manufacture this material power contact part.
Improve as of the present invention another, described properties-correcting agent also comprises synthetic rubber.Can effectively improve shock resistance by synthetic rubber, the performance of the moulding that has dynamic fit is also promoted.
As the optimal technical scheme of the present embodiment, described synthetic rubber comprises: the mixture of terpolymer EP rubber and styrene-butadiene rubber(SBR).
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claim provide, with and dependent claims.
