Abstract
The present invention relates to an epoxy resin nanometer composite material which comprises 40 to 95% of epoxy resin, 0.1 to 10% of organized rectorite and 1 to 59% of curing agent used for epoxy resin. The present invention also provides a preparation method of the epoxy resin nanometer composite materials, which comprises the following steps: adding the organized rectorite to the epoxy resin; heating the epoxy resin to be melting; adding and uniformly stirring the epoxy resin curing agent to the mixture of epoxy resin and the rectorite which are stirred in a vacuum pumping mode; pouring the mixture in a mould and molding the mixture at 60 to 160 DEG C by solidifying. The preparation method of the present invention is simple, and the obtained epoxy resin nanometer composite material has the advantages of preferable toughness, high shock resistance, excellent heat resistance and low cost.
Description
Technical field
The present invention relates to a kind of epoxy resin nano composites and preparation method thereof.
Background technology
The casting material of existing model, instrument, electrical equipment, sheet metal mould adopts Resins, epoxy usually.Resins, epoxy is fragility, and impact resistance is bad, and resistance toheat also has much room for improvement.The needs of higher model, instrument, electrical equipment, sheet metal mould etc. are difficult to meet the demands.
Summary of the invention
The present invention provides a kind of epoxy resin nano composites and preparation method thereof at the problems referred to above exactly, and the gained epoxy resin nano composites has toughness and resistance toheat preferably, and with low cost.
Technical scheme provided by the invention is: a kind of epoxy resin nano composites comprises 40～95% Resins, epoxy, 0.1～10% the rectorite leng that organises, 1～59% hardener for epoxy resin; The rectorite leng that wherein organises is nano-sheet and is dispersed in the epoxy matrix; Above per-cent is mass percent.
The above-mentioned rectorite leng that organises obtains by the following method: be that 2～8: 1 ratio is with water and rectorite leng mixing and stirring in mass ratio; In the mass ratio of organic amine and rectorite leng is that 1: 2～10 ratio is got organic amine, adds entry in organic amine, and the mass ratio of organic amine and water is 1: 10～20, drips acid again and makes pH value less than 7, makes organic amine change into ammonium salt; Subsequently with joining ammonium salt slowly be added in the mixture of above-mentioned water and rectorite leng, stir, filter, oven dry promptly gets the required rectorite leng that organises.
Also contain mass percent in the above-mentioned epoxy resin nano composites and be 0.1～0.5% reactive thinner.
The present invention also provides the preparation method of above-mentioned epoxy resin nano composites: the rectorite leng that organises is joined in the Resins, epoxy, add reactive thinner in case of necessity, be heated to the resin fusing then, vacuumizing stirring back adding epoxy curing agent stirs, pour mould again into, at 60 ℃--160 ℃ of curing moldings.
Preparation method of the present invention is simple, and the gained epoxy resin nano composites has toughness preferably, and not only impact resistance is good, and resistance toheat is superior, and is with low cost.Rectorite leng becomes the nano-dispersed shape in Resins, epoxy, can see with electron microscopy observation, can't see diffraction peak with the X diffractometer, rectorite leng is peeled away into nano-sheet by Resins, epoxy and is dispersed in the epoxy matrix, model, instrument, electrical equipment, sheet metal mould that the present invention makes as casting material.
