Description
Technical field
The present invention relates to field of compound material, particularly a kind of epoxy resin composite material and preparation method thereof.
Background technology
Epoxy resin is the organic compound referring to and containing two or more epoxide groups in molecule, in addition to indivedual,
Their relative molecular mass is the highest.The molecular structure of epoxy resin is to contain active epoxide group in strand for it
Feature, epoxide group may be located at the end of strand, centre or structure circlewise.Owing to molecular structure containing active ring
Oxygen groups, makes them can crosslink reaction with polytype firming agent and is formed and insoluble have the cancellated height of three-dimensional
Polymers.In all molecular structures, the macromolecular compound containing epoxide group is referred to as epoxy resin.Epoxy resin tool after solidification
Having good physics, chemical property, it has the adhesive strength of excellence to the surface of metal and nonmetallic materials, and dielectric properties are good
Good, deformation retract rate is little, product size good stability, and hardness is high, and pliability is preferable, to alkali and major part solvent-stable, thus
It is widely used in national defence, each department of national economy, pours into a mould, impregnate, be laminated the purposes such as material, bonding agent, coating.
Epoxy resin can not be used alone, it is necessary to is blended with firming agent, crosslinks reaction and could form the netted of solid
Structure, just can embody the performance of excellence, thus be applied to every field.But after epoxy resin cure, crosslink density is big, deposits
Crisp in matter, that thermostability is poor, fatigue durability is weak etc. is not enough and limit the range of application of epoxy resin.At present, epoxy resin
Performance cannot meet social need with rapid changepl. never-ending changes and improvements, but people are by filled rubber, plastics, nothing in epoxy resin-base
Machine nano materials etc., improve the heat energy of epoxy resin, luminous energy, mechanical property etc. so that it is adapt to the development of modern science and technology.

15 prepare with silane coupler modified.
Further, described modified mesoporous material SBA-15 is to be scattered in toluene by mesoporous material SBA-15, adds
Silane coupler modified form.
It is further preferred that described silane coupler is γ-mercaptopropyl trimethoxysilane KH580, silane coupler second
One in thiazolinyl triethoxysilane KH151 etc..
Further, described mesoporous material SBA-15 is spherical, and particle diameter is 7-10nm.
The preparation method of a kind of epoxy resin composite material, comprises the following steps: (1) prepares modified mesoporous material SBA-
15: 2.0g mesoporous material SBA-15 is dispersed in 30mL toluene, add 5mL silane coupler γ-mercapto propyl group front three
TMOS KH580, moves in magnetic force water-bath, after 40min being stirred at room temperature under nitrogen protection, is heated to 80 DEG C of constant temperature
Reaction 15h, naturally cools to room temperature, washs 4-5 time with toluene, is dried more than 48h, successfully prepares modified mesoporous material at 60 DEG C
Material SBA-15；(2) preparation of epoxy resin composite material: by weight, by 100 parts of epoxy resin, 80-100 part polyamide
Firming agent, 0-2 part modified mesoporous material SBA-15 mechanical blending are uniform, evacuation, and in injection mould, cold curing 3-5 days, de-
Mould and prepare described epoxy resin composite material.
Owing to using technique scheme, the method have the advantages that
Generating many hydroxyls in epoxy resin solidification process the most of the present invention, hydroxyl is with modified mesoporous material SBA-15's
Silicone hydroxyl dehydrating condensation generates " organic and inorganic " infiltration tangled structure, so the addition of modified mesoporous material SBA-15 can improve
The mechanical property of epoxy resin composite material.
2. in the present invention, in silane coupler, γ-mercaptopropyl trimethoxysilane KH580 has mercapto functional group, vinyl
Containing C=C double bond in triethoxysilane KH151, for modified mesoporous material SBA-15, impart mesoporous material SBA-15 new
Functional group, improve mesoporous material SBA-15 dispersibility in the epoxy, thus improve epoxy resin further and be combined
The mechanical property of material, hot strength can reach original 25%-50%.
3. the present invention uses polyamide curing agent so that epoxy resin composite material can at room temperature just can curing molding,
And this composite good springiness.
4. the preparation method of present invention technique on the whole is simple, it is easy to implement.
