Description
Technical field
The present invention relates to field of high polymer material processing, and in particular to a kind of good surface HI high impact warpage preventing nylon/POK conjunction
Gold and preparation method.
Background technique
Nylon, i.e. polyamide (PA) are a kind of high-molecular compounds on main chain containing amide group, are that dosage is maximum
General engineering plastic.Because forming " hydrogen bond " effect containing a large amount of highly polar amide groups in main chain, leading to intermolecular combination
Power is significantly increased, so that nylon resin be made to have excellent mechanical performance, can be widely applied to industrial circle.Wherein, PA66 is again
Be Typical Representative and PA6 in general nylon all it is the maximum general nylon of dosage, there is intensity more higher than PA6, heat-resisting etc.
Advantage is mainly used in automobile and electric field.But PA66 also has the disadvantages of water absorption rate is high, and brittleness is big, crystallization is too fast simultaneously,
It is poor so as to cause dimension stability, need to carry out toughening modifying, enhancing is contemplated that floating fine problem of leakage when modified, give
Products application brings many restrictions.
Polyketone (POK) is a kind of Novel engineering resin newly emerged in recent years, with carbon monoxide, alkene (ethylene,
Propylene) it is the environmental protection type resin that monomer synthesizes, have excellent impact resistance, wearability and temperature tolerance, wearability is POM
14 times, it is that one kind is answered that thermal deformation, which also can achieve 210 (0.45MPa), while also have the advantages that outstanding weather-proof, low water suction
With the new material having a bright future.But also have some intrinsic defects, if intensity and modulus is low, can by chemical modification come
Make up this disadvantage.
Currently, there is some reports about POK/ nylon alloy on the market, such as prior art discloses a kind of water-fast depolymerization
Amide composite material describes a kind of preparation method for enhancing POK/PA alloy, improves hydrolytic resistance by addition hydrolysis agent
Energy；Also prior art discloses a kind of polyamide/polyketone alloy materials, describe the PA/POK alloy strengthening material of addition anti-wear agent
Material；There are also prior art discloses a kind of antistatic low warpage POK-PA alloy material of high mill, describe addition conductive black and
Anti-wear agent PTFE and filler achieve the effect that antistatic, wear-resisting and that resist warping.But these presently disclosed alloys, although mechanical
Performance obtains a degree of promotion, but product usually has the problems such as surface floating fiber is serious.
It would therefore be highly desirable to provide a kind of good surface high impact nylon/POK alloy.
Summary of the invention
Based on this, the main object of the present invention is to provide a kind of good surface high impact nylon/POK alloy.The alloy exists
PA66/6 resin and polyketone are introduced simultaneously in PA66 resin, surface floating fiber can be avoided to ask while taking into account high impact property
Topic.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of good surface high impact nylon/POK alloy, the alloy prepare each component that raw material includes following mass parts:
