Description
Technical field
The present invention relates to epoxy resin nano composites.Especially epoxy resin nano composites preparation method.
Background technology
At present, adopt nano-TiO

2The organic illiteracy holder soil of laminated clay, sepiolite and epoxy resin prepare nano composite material; Through the deployment conditions of transmission electron microscope research nanoparticle in epoxy resin-base; The second-order transition temperature that adopts DTA to test different epoxide resin nano matrix materials, the result shows that nanoparticle is scattered in the matrix, and the second-order transition temperature of epoxy resin is improved.The Chinese epoxy resin of certificate employer's organization expert introduction is scattered in the epoxy resin-base nanoparticle and clay particle through certain mode, and the second-order transition temperature of epoxy resin is increased substantially, and can improve 50 ℃ at most.
The thermotolerance of polymkeric substance is one of condition of the decision polymkeric substance scope of application, and the stable on heating raising of polymkeric substance can enlarge the use range of polymkeric substance.Improve the stable on heating approach of resin and have 3: increase the polymer chain rigidity; Make polymer crystallization; Increase the degree of crosslinking of polymkeric substance.These 3 kinds of methods certainly will make the toughness of polymkeric substance lose to some extent.Nano material is meant the material of median size below 100 nm, owing to have sizable phase interface area, makes it have the not available novel physical of many macro objects, chemical property.Through the dispersion of meticulous control nano material in superpolymer and compound, can in the more weak microcell of resin, play reinforcement, filling, increase interface interaction power, reduce the effect of free volume.Only, just can in 1 sizable scope, improve the over-all properties of matrix material effectively, not only play enhancing, toughness reinforcing, aging-resistant effect, and do not influence Drawing abillity with seldom inorganic particulate volume content.
Summary of the invention
To the problems referred to above, the present invention provides the epoxy resin nano composites preparation method.
The epoxy resin nano composites preparation method is: join in the acetone at following surface treated nanoparticle of whipped state; Use the ultrasonication dozens of minutes then; Under whipped state, above-mentioned solution and epoxy resin are mixed solvent; Be warming up to 13 0 ℃ of reaction th, on the high speed homogenization dispersion machine, disperse 2 0min, cooling back to add an amount of solidifying agent again and mix; Water the people after finding time to outgas and scribble in the good steel die of releasing agent and preheating, through the demoulding of 50 ℃/5h of 13 0 ℃/5 h+1 completion of cure postcooling.
Epoxide resin nano composite property testing method is: the mensuration of second-order transition temperature adopts USATAM DSC2910, and at N, heat-up rate is 20 ℃/mi n under the atmosphere; And the casting matrix TEM analysis is used the transmission electron microscope of unit type as H-6 00 types, observes the deployment conditions (sample cut into lu m thick) of nanoparticle.China epoxy resin employer's organization expert introduction is said; The expert has successively investigated nano particle to the resin glass Influence of Temperature: along with the adding cross-linking density of nanoparticle increases; Second-order transition temperature is raise it is thus clear that the adding of nanoparticle can make the second-order transition temperature of system obviously raise, improve the thermotolerance of system; Clay is to the influence of epoxy-resin systems second-order transition temperature: sepiolite becomes fibrous and is scattered in the resin, has played the effect of primitive fiber enhanced, thereby the second-order transition temperature of epoxy resin is improved.
