The invention relates to a composite of reinforced nylon 66 of warp resistance, which is made up of 40 to 75 percent of nylon, 10 to 30 percent of glass fiber, 10 to 30 percent of kaolin, 1 to 10 percent of compatilizer, 0 to 1 percent of antioxidizer and 0 to 1 percent of lubricant. The preparing technique comprises the following steps: raw materials are scaled and taken according to weight percentage; the raw materials except for glass fiber are put into a high mixing machine to be mixed for 2-5 minutes; the materials are taken out; the mixed materials adding with the glass fiber are put into a screw compressor for extruding prilling. The rotating speed of the screw compressor is 180-600r/min and temperature is 240-280 DEG C. The invention has the advantages of excellent dimensional stability, good capability of warp and deformation resistance, very good rigidity and high heat resistance.
Description
Technical field
The present invention relates to a kind of composite enhancement nylon 66 composition of warpage-resistant, this material has excellent comprehensive mechanical properties and high dimensional stability, be applicable to electrical part product with high requirement, but injection moulding low-voltage vacuum contactor, isolating switch, low-tension switch, the electric element of thin-walled, power tool housing etc. are higher and do not produce the goods of distortion to dimensional requirement, belong to the modified polyamide technical field.
Technical background
Nylon 66 is even thermoplastic polyesters that a kind of molecular structure includes 6 symmetrical methylene radical, have high strength, wear-resisting, anti-solvent, advantage such as self lubricity is good and the use temperature scope is wide, be one of the widest engineering plastics of purposes, be widely used in various electronic electric equipments and household appliances.
Along with developing rapidly of the electric industry of China, the input energetically of capital construction, growing for the demand of the enhancement engineering material of dimensional stability.As low-voltage vacuum contactor, isolating switch, low-tension switch, the electric element of thin-walled, power tool housing etc. all need to have the good comprehensive mechanical property, the engineering plastics of warpage-resistant dimensional stabilizing, and wherein with the consumption maximum of polyamide material.Single glass fibre strengthens PA66 and has the excellent comprehensive performance, but the fiber condition of glass fibre itself has determined that its orientation is an anisotropy, this cause the PA66 material in being injection molded into the crystallisation process of goods each to contraction inconsistent, make the finished product the phenomenon of buckling deformation can occur, directly influenced its service condition.
Summary of the invention
The object of the present invention is to provide a kind of have good warpage-resistant and mechanical property, can be used for the composite enhancement nylon 66 composition of the warpage-resistant of various electronic apparatuss, power tool and automotive field.
For realizing above purpose, technical scheme of the present invention provides a kind of composite enhancement nylon 66 composition of warpage-resistant, it is characterized in that, is made up of following weight percent:
