Description

A kind of high heat conduction tenacity acrylic's ester rubber
Technical field
The present invention relates to a kind of acrylate rubber, be specifically related to one and there is high heat conduction, elastomeric acrylate rubber Glue.
Background technology
Acrylate rubber refers to acrylate for main monomer through elastomer obtained by copolymerization, and its main chain is saturated carbon Chain, side base is polar ester groups, and it has the performances such as excellent heat-resisting, ageing-resistant, oil resistant, resistance to ozone, uvioresistant, mechanical property Being better than fluorubber and silicone rubber with processing characteristics, its heat-resisting, resistance to ag(e)ing and oil resistivity are better than nitrile rubber, and it is widely used in In various high temperature, resistance to oil environment.
Acrylate rubber is when being used as loading structure packing ring under hot conditions, and, heat conductivity, elasticity heat-resisting to it have Very high request, existing product is all difficult to life-time service, needs frequently to change.The present invention is directed to this problem carried out in detail Research, finally give and there is excellent heat conducting, heat-resisting, elastic acrylate rubber, can high temperature, heavy burden machinery in use Make packing ring, use the cycle long.
Summary of the invention
Goal of the invention: the present invention provides a kind of high heat conduction tenacity acrylic's ester rubber, it has good heat conductivity, resistance to Hot and elastic, can meet high temperature, heavy burden machinery in be used as the demand of packing ring.
The present invention provide acrylate rubber by combed acrylate rubber 100 weight portion, elastomer 20-40 weight portion, Compatilizer 3-6 weight portion, plasticizer 2-8 weight portion, toughener 15-35 weight portion, coupling agent 3-5 weight portion, vulcanizing agent 1-3 weight Amount part, pigment 0-5 weight portion and compounded mix 36-80 weight portion composition.
Present invention uses combed acrylate rubber and polyurethane nano microsphere toughener.Acrylic rubber is as elasticity Body, in the polymerized segment that its side chain graft is certain, forms comb structure, serves the buffering between main chain section, receive external force Extruding, side chain section folds, buffers.
The combed acrylate rubber of described combed acrylate rubber more preferably lateral chain grafting polyester resin, Polyester resin preferably comprises Merlon segment, and Merlon, as segment, which raises resistance to elevated temperatures and improves, but content is too Promoting further of low resistance to elevated temperatures is inconspicuous, and content is the highest, can cause elastic reduction, therefore Merlon segment accounts for total polyester Resin quality is most preferably 30-50%.
Using polyurethane nano microsphere toughener further, it is dispersed in acrylate rubber, and polyurethane nano microsphere rises Having arrived good cushioning effect, external force peptizaiton is excellent, and effect is much better than other kinds of toughener.
Combed acrylate rubber and polyurethane nano microsphere with the use of, reached stress dispersion to greatest extent. Toughener is preferably polyester resin grafted polyurethane Nano microsphere further, makes polyurethane nano microsphere gather with matrix side chain graft The combed acrylate rubber of ester resin reaches high compatibility.
Described elastomer is SEBS, SBS, SIS or SEPS, and the use of elastomer further increases wilfulness, in order to realize It is the most identical with matrix, adds suitably to peer.Consider the resistance to elevated temperatures of elastomer further, therefore most preferably SEBS、SEPS。
Another important performance of the present invention is resistance to elevated temperatures, and it is quickly derived based on by heat, therefore described being combined is filled out Material is CNT and spherical aluminium sesquioxide, and weight ratio is 3-5:1.CNT and spherical aluminium sesquioxide formed " point- Line " connect, the coupling agent added in component makes contacting of filler and acrylate rubber, CNT and spherical aluminium sesquioxide More stable, heat conductivity is more preferably.
As further preferably, CNT nano silver wire filling carbon nano-pipe.
Silver is as a kind of high-thermal conductive metal, and nano silver wire is filled in CNT, and heat is quickly formed at CNT Space in pass to, affected less by outer acrylate rubber, it is possible to achieve heat quickly passes to, this is simple silver nanoparticle Line, CNT are beyond one's reach.
Described vulcanizing agent is polyamine vulcanizing agent, preferably diethylenetriamine, triethylene tetramine, TEPA, 1,6- Hexamethylene diamine.
Described coupling agent is amino silicane coupling agent, can be A-1100, A-1110,1-1120, A-1130, KBM-602, South big-42, southern big-73.
Described pigment is Chinese white, red pigment, black pigment, blue pigment, viridine green, silver, gold Pigment, gray paint and mixture thereof.Pigment carries out mixture according to actual color.
Technique effect: multicomponent is selected and combined by the present invention, be specially use combed acrylate rubber with Polyurethane nano microsphere toughener coordinates, and plasticizer and elastomer are to use to improve elasticity so that it is be adapted to high answering The dispersion of power, weighs effective;Use the proportioning of nano silver wire filling carbon nano-pipe and spherical aluminium sesquioxide special ratios, real Show high heat conduction;Further preferably combed acrylate rubber and the polyester resin grafted polyurethane of lateral chain grafting polyester resin is received Meter Wei Qiu improves again elasticity;The selection of SEBS and SEPS can also improve resistance to elevated temperatures.The combination of above-mentioned each component and use Amount selection is to there is mutual synergism between specific selection, each component, improves heat conductivity, high temperature resistant and elastic, its It is much better than the simple superposition of independent component.
