Description
Technical field
The invention belongs to high polymer material and its preparing technical field, and in particular to a kind of daiamid composition/acrylic acid
Ester rubber dynamic vulcanization glue, and further relate to its preparation method.
Background technology
In recent years, the dynamic vulcanization glue (TPV) in thermoplastic elastomer (TPE) family is developed rapidly, because it has rubber concurrently
The excellent processing characteristics of high resiliency and thermoplastic are thus built in electric wire, auto parts machinery, various encapsulant, building
Build, the field application such as medicine equipment it is very extensive.Meanwhile thermoplastic sulfurized rubber can replace rubber to be largely used in PVC, PE and PP etc.
General the thermoplastic resin even modified aspect of the engineering plastics such as PU, PA, CA, plastics industry is set brand-new situation occur.
It using acrylate is main monomer through elastomer obtained by copolymerization that ACM (ACM), which is, and its main chain is saturation
Carbochain, side base are polar ester groups, and it is (heat-resisting resistance to that special structure assigns its excellent high-temperature oil resistance, long term high temperature performance
Aging), but its high and low temperature resistance, cold resistance, water resistance are bad.The surface energy of polyamide (PA) relatively, there is foot with ACM
Enough affinity, and polarity differs smaller with solubility parameter, thus there is good compatibility.Chinese patent
CN105255082A discloses a kind of ACM/nylon thermoplastic's vulcanizate and preparation method thereof, prepared by this method
Vulcanizate has excellent oil resistant, resistance to elevated temperatures, keeps rubber elastomeric while has plasticity, but should

The water absorption rate of three kinds of monomer nylon is all higher, and necessary high temperature drying, complex manufacturing, cost are high before processing.
Chinese patent CN104513434B recommend have " a kind of butyl rubber/Long Carbon Chain Polyamide thermoplastic sulfurized rubber and its
Preparation method " and CN105037967A are provided with " a kind of butyl rubber/polyamide thermoplastic vulcanizate and preparation method thereof ",
The common feature of two patents is to carry out dynamic vulcanization with butyl rubber (IIR) and polyamide, although butyl rubber it is water-fast,
There is the advantages of big in terms of resistance to air-tightness, weatherability, but be compared to for ACM (ACM)：First, heat resistance and length
Phase high-temperature behavior can not match in excellence or beauty with ACM；Secondly, IIR oil resistivitys are poor, remote in terms of resistance to hydrocarbon oil, fatty hydrocarbon ils and mineral oil
Not as ACM；3rd, IIR are non-polar materials, and polyamide is polar material, between the two poor compatibility, even if adding increase-volume
Agent, also there is bad influence to the overall performance of material.And ACM inherently polar materials, it can phase well with polyamide
Hold, the preferable impact of performance can be obtained.
