Abstract
The present invention discloses an in-situ and inclusion polymerization process of preparing composite nano particle/epoxy resin material. The epoxy resin is biphenol A type epoxy resin; and the nano particle is nano SiO2, nano montmorillonite, nano TiO2, nano CaCO3 or nano ZnO. Via the in-situ polymerization and inclusion polymerization on the surface of nano inorganic particles, the inorganic nano particles with strong autoagglutination are dispersed homogeneously in epoxy resin matrix. The preparation process using water as solvent is simple, low in cost and less pollutant, needs no solvent recover equipment and is favorable to application in industry.
Description
Technical field
The present invention relates to the technology that a kind of original position and parcel polymerization prepare nanoparticle/epoxy resin composite material.
Technical background
Resins, epoxy is the important kind in the synthetic resins field, and it is celebrated with mechanical property, electric property and the adhesive property of excellence.At present, Resins, epoxy has been widely used in fields such as tackiness agent, coating, insulating material, structured material.In industry such as electric, machinofacture, aviation, boats and ships and Defence business, play an important role.China's Resins, epoxy develops rapidly since the nineties in 20th century, but throughput only accounts for 9% of world's overall throughput.It is bigger that China's Resins, epoxy industry and external advanced level are compared gap, is mainly reflected in that Technology is backward, kind is few, of poor quality, and low-and-medium-grade products is in the majority, especially extraordinary and functional product is less, can not satisfy domestic needs.
There are a lot of bibliographical informations Resins, epoxy to be carried out modification in recent years, can obviously improve performances such as its tensile strength, tensile modulus, shock strength with nano material.The bending of having reported exfoliated epoxy/18-Mont nano composite material as Lv Jiankun etc. (117 pages of " matrix material journal " the 19th the 1st phases of volume) and shock strength are compared with the Resins, epoxy of not filling nanoparticle when nano particle content is 2%~3% (wt) and have been improved 10% and 50% respectively.Dong Yuancai etc. (37 pages of " plastics industry " the 27 the 6th phases of volume) have reported with nano-TiO
2Resins, epoxy/nano-TiO for filler
2Matrix material, when the filling quality mark was 3%, the modulus in tension of material improved 370% than unmodified epoxy resin, drew Zhong Qiangdu to improve 44%, and shock strength improves 878%, and other performances also are significantly improved.Usually these modifications realize by inorganic nano-particle and the direct blend of Resins, epoxy; And often be difficult to inorganic particles is uniformly dispersed with this method; Especially when particle is nano level, because density and polar difference and the effect of nanoparticle intensive autohemagglutination, being difficult to reach real nanometer state disperses, there are many particulates to be in aggregating state, thereby make many advantages of nanoparticle modified epoxy resin composite not demonstrate fully out.People make the nanoparticle novel method of disperse in epoxy matrix material fully in exploration always.
Summary of the invention
For nanoparticle can be scattered in the epoxy matrix material with nano-scale, the invention provides the technology that a kind of original position and parcel polymerization prepare nanoparticle/epoxy resin composite material.
The objective of the invention is to realize by following technical scheme:
1, its technical process is:
1), dihydroxyphenyl propane and mass concentration be 5%~30% NaOH solution in the mol ratio of dihydroxyphenyl propane: NaOH are that 1: 1.1~1: 1.8 ratio is put into reactor, heat up and start and stir, 65 ℃~75 ℃ dissolvings down, be cooled to 50 ℃ then, add inorganic nano-particle, stir speed (S.S.) is controlled at 100~1500r/min, and nanoparticle is well dispersed in the medium;
2), drip epoxy chloropropane down at 50 ℃, dihydroxyphenyl propane: the mol ratio of epoxy chloropropane is 1: 1.1~1: 1.8, is warmed up to 80 ℃~95 ℃ after dropwising, and reaction 1.5~9hr injects cold water later on, treat to stop to stir after resin sinks, remove water, open and stir and injection hot water, inject cold water behind the stirring 15min, stop to stir and remove water, so repeat to equal to stop in 7 o'clock, carry out normal pressure dehydration and decompression dehydration drying then until pH value, must nanoparticle/epoxy resin composite material.
2, the Resins, epoxy that obtains is bisphenol A type epoxy resin.
3, nanoparticle is nanometer SiO
2Or nano imvite or nano-TiO
2Or nanometer CaCO
3Or nano-ZnO.
4, the add-on of nanoparticle accounts for 1%~30% of resin total mass.
The present invention compares with background technology, and the useful effect that has is: make the abundant disperse of inorganic nano-particle energy with extremely strong self aggregation effect in epoxy matrix material by in-situ polymerization and parcel polymerization; Take the method for a step washing prepare the technical process of nanoparticle/epoxy resin composite material simple, easy to operate, solvent recovery unit need be set, owing to make water make solvent, novel process is polluted few simultaneously, cost is low, helps industrial practical application.
