Abstract
The invention discloses super-tough nylon. The super-tough nylon is characterized by comprising the following components by weight: 55 to 75 percent of nylon 6, 5 to 15 percent of ultra-fine barium sulfate, 10 to 20 percent of POE-g-MAH, 0.1 to 0.3 percent of antioxidant 1010, 0.2 to 0.5 percent of antioxidant 168, and 0.3 to 0.7 percent of lubricant TAF. A method for preparing the super-tough nylon is characterized by comprising the following steps that the nylon 6 resin, the ultra-fine barium sulfate, the POE-g-MAH, the antioxidant 1010, the antioxidant 168 and the lubricant TAF are mixed well, put into a double-screw extruder, fully melted and compounded in the double-screw extruder, extruded through a nose, pulled into strips, cooled, palletized, dried and packaged. The invention aims to overcome the deficiencies of the prior art and provide the super-tough nylon with low mold shrinkage and good dimensional stability. Another aim of the invention is to provide a method for preparing the super-tough nylon.
Description
Technical field
The present invention relates to a kind of super-toughened nylon, particularly a kind of super-toughened nylon with low molding shrinkage and good dimensional stability the invention still further relates to a kind of method for preparing above-mentioned super-toughened nylon.
Background technology
Polymeric amide (being commonly referred to nylon) is an output maximum in the five big general engineering plastic, kind is maximum, purposes is the widest, the base resin of high comprehensive performance.Nylon is very outstanding in the performance of aspects such as flexural strength, wear-resisting, anti-creep, electrical property, but the low temperature resistant toughness of most nylon kind is not ideal enough, therefore, has influenced the application in the occasion of outdoor applications such as railway equipment, trolley part.
Super-toughened nylon mainly is by adding rubber elastomer, thermoplastic elastomer, metallocene-polyolefin etc., making through the twin screw extruder blend as a big kind of modification of nylon.Simultaneously, toughner generally all is by the graft copolymerization polar group, the consistency of amino by polar group and nylon tip or carboxyl reaction and Reinforced Nylon resin and toughner.The adding of toughner can significantly improve the shock strength of nylon and lower temperature resistance but because there is molding shrinkage shortcoming bigger than normal in nylon itself, toughner be added in the molding shrinkage that has increased nylon to a certain extent.Because it is bigger to prepare the required toughner addition of super-toughened nylon, generally all more than 15%.During the goods of the big or big part of preparation wall ratio, be easy to produce deformation, be difficult to satisfy the demanding occasion of dimensional stability.
Summary of the invention
The objective of the invention is provides a kind of super-toughened nylon with low molding shrinkage and good dimensional stability in order to overcome weak point of the prior art.
Another object of the present invention is for a kind of method for preparing above-mentioned super-toughened nylon is provided.
In order to achieve the above object, the present invention adopts following scheme:
A kind of super-toughened nylon is characterized in that comprising by weight percentage following component:
Nylon 6 55-75%
Ultramicro Barium Sulfate 5-15%
POE-g-MAH 10-20％
Antioxidant 1010 0.1-0.3%
Antioxidant 168 0.2-0.5%
Lubricant TAF 0.3-0.7%
A kind of method for preparing above-mentioned super-toughened nylon is characterized in that may further comprise the steps:
Nylon 6, Ultramicro Barium Sulfate, POE-g-MAH, antioxidant 1010, oxidation inhibitor 168, lubricant TAF are mixed the back to be dropped in the twin screw extruder, fully fusion in twin screw extruder, compound, through head extrude, tie rod, cooling, pelletizing, drying, packing at last.
In sum, beneficial effect of the present invention:
The present invention utilizes the superfine packing material within the specific limits to the smaller characteristics of toughness influence of super-toughened nylon by introduce the Ultramicro Barium Sulfate filler in toughened system, and the universal feature that also the possesses packing material molding shrinkage that promptly increases the rigidity of product and dimensional stability and reduce goods.The superfine packing material reaches same toughening effect when need not increasing or increasing the toughner addition on a small quantity, and improves the dimensional stability of material, the molding shrinkage of reduction goods.
