Abstract
The present invention discloses one kind of polyethylene/thermosetting resin composite material with melt flowability, and the composite material consists of polyethylene 10-90 wt%, thermosetting resin 0.5-70 wt%, compatibilizer 0-50 wt%, curing agent 0.1-35 wt% and lubricant 0.1-5 wt%. The composite material has thermal plasticity, excellent flowability, capacity of being formed in common plastic forming method and excellent comprehensive performance. Compared with polyethylene, the composite material has 10-100 % raised tensile strength, 10-200 % raised impact strength and 10-80 % raised melt strength.
Description
Technical field
The present invention relates to a kind of polythene material.
Background technology
Polyethylene is a kind of general purpose material, has the good comprehensive performance, and purposes is very extensive, but because its strength ratio is lower, and resistance toheat is not high, its application has been subjected to very big restriction.In order to improve its deficiency, enlarge its Application Areas, the investigator has carried out number of research projects, up to the present, the main method that adopts is: (1) adds toughener, by adding preparation polyethylene based compositions such as mineral filler (as mica, talcum powder, kaolin etc.), fiber (as glass fibre, carbon fiber, steel fiber etc.), whisker (ZnOw, calcium carbonate crystal whisker etc.), thereby improve performances such as intensity and thermotolerance, but this method the toughness and the melt strength of material have been reduced; (2) crosslinked, can improve thermotolerance and intensity by making polyethylene crosslinking, poly crosslinked mainly contain radiation and chemically crosslinked, these two kinds of methods all will increase equipment, and cost is improved.
Summary of the invention
The purpose of this invention is to provide a kind of melt flowable polyethylene/thermosetting resin composite material.
The objective of the invention is to realize in the following way: a kind of melt flowable polyethylene/thermosetting resin composite material, form by following components in weight percentage thing: polyethylene 10～90%, thermosetting resin 0.5～70%, expanding material 0～50%, solidifying agent 0.1～35%, lubricant 0.1～5%.
Thermosetting resin comprises Resins, epoxy, unsaturated polyester, resol, aminoresin, acrylate.
Expanding material comprises two classes: the multipolymer of vinyl monomer and polar monomer, poly graft copolymer.
The multipolymer of vinyl monomer and polar monomer is ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-methyl acrylate, ethylene-propylene acetoacetic ester.
Poly graft copolymer is polycthylene grafted maleic anhydride, methyl propenoic acid glycidyl alcohol ester, vinylformic acid and ester class thereof, acrylamide.
The present invention has following beneficial effect, and thermosetting resin in-situ solidifying and being uniformly dispersed under the polyethylene molten state adopts expanding material to improve interface interaction power between polyethylene and thermosetting resin, and this matrix material has good flowability.The present invention shows the performance of thermoplastic material, has good flowability, can adopt the method moulded products of general plastic shaping, the present invention has good comprehensive performances, compare with pure polyethylene, tensile strength improves 10-100%, and shock strength improves 10-200%, melt strength improves 10-80%, can improve intensity, toughness, resistance toheat and melt strength simultaneously.
Embodiment
The present invention for realizing the processing technology routine that technical scheme is taked is: (1) two-step approach, part polyethylene, polar polyethylene, thermosetting resin and solidifying agent are carried out melting mixing, the first mixed thing that preparation has certain flowability will just mix thing again and prepare matrix material with remaining polyethylene and polar polyethylene melting mixing; (2) single stage method, with all raw materials and auxiliary agent measure in proportion mix after, carry out melting mixing and prepare matrix material, perhaps with after raw material and the auxiliary agent metering, thermosetting resin and auxiliary agent are added in the fused polyethylene system stage by stage, prepare matrix material.The common objective of two kinds of technological lines is thermosetting resin homodisperse in the polyethylene system.
The present invention will be further described below in conjunction with embodiment:
Embodiment 1
Get polyethylene 100g, Resins, epoxy 20g, with maleic anhydride grafted polyethylene 76g and 1,6-hexanediamine 3g makes solidifying agent, and Zinic stearas 1g does lubricant, adopts single stage method to prepare matrix material.Detect performance by the injection molding sample, compare with polyethylene, tensile strength has improved 60%, and shock strength has improved 60%, and Vicat softening point has improved 5 degree, and melt index becomes 0.85g/10min (illustrating that melt strength has increased) by 2.5g/10min.
Embodiment 2
Get polyethylene 120g, unsaturated polyester resin 25g, make solidifying agent with vinylbenzene 5g and maleic anhydride grafted polyethylene 30g, EAA (ethylene-acrylic acid copolymer) 19g is an expanding material, and erucicamide 1g is a lubricant, adopts two-step approach to prepare matrix material.Detect performance by the injection molding sample, compare with polyethylene, tensile strength has improved 35%, and shock strength has improved 70%, and Vicat softening point has improved 4 degree, and melt index becomes 0.65g/10min (illustrating that melt strength has increased) by 2.5g/10min.
