Description
Technical field
The present invention relates to powder coating technology field, particularly relate to the montmorillonite intercalation polymeric modification that a kind of impact resistance is good
Epoxy resin based powder coating and preparation method thereof.
Background technology
Along with the enhancing of mankind's environmental consciousness, solvent based coating is gradually restricted, and development meets the coating of environmental requirement
Being trend of the times, Water-borne modification and solvent free coating are the directions of paint field development from now on.Powdery paints is a kind of novel
Without solvent 100% solid powdery coating, there is the advantages such as high usage, easy application, corrosion-resistant, environmental protection, the modern times spray
It is widely applied with in corrosion-resistant field.
Epoxy powder coating is a kind of important new coating that development in recent years is got up, with the material profit that it is higher
Heavier status is occupied with rate, stronger adhesive force and antiseptic property coating industry the most at home.In recent years, nanometer material
The development of material opens the frontier of material science, and nanometer particle-modified corrosion-resistant epoxy paint also has vast potential for future development.
Montmorillonite belongs to phyllosilicate, has the lattice arrangement of high-sequential.Utilize montmorillonite and the asphalt mixtures modified by epoxy resin with layer structure
Fat intercalation synthesis is prepared the research of a kind of high-performance epoxy resin based powder coatings and is received much concern, and epoxy resin based powder coating passes
System modification is that modifying agent montmorillonite is disposably joined the twin-screw extrusion stage, when hot setting, makes limellar stripping, this side
Method montmorillonite intercalation in the epoxy and peel off insufficient, the antikathode affecting powdery paints is peeled off and water boiling resistance performance.
The research of epoxy resin and performance powder coating thereof " the montmorillonite intercalation polymerization prepare " utilizes low molecular weight epoxy tree
Fat (E-51) inserts stratiform organo montmorillonite (OMMT), by intercalation polymeric and bisphenol-A and the 3rd component 2,6-di-t-butyl
P-methyl phenol (BHT) reacts, and obtains a kind of powder coating epoxy resin.The test of X x ray diffraction shows, stratiform is received
Rice montmorillonite layer is stripped completely, is dispersed in resin matrix.Control montmorillonite and add total amount and twice additional proportion,
The antikathode that can be obviously improved this coating is peeled off and water boiling resistance performance.
But, montmorillonite belongs to inorganic mineral, by adding montmorillonite at twice, makes montmorillonite prepare rank at epoxy resin
Section is by abundant intercalation and stripping, but both poor compatibility, the levelability of film certainly will be affected, meanwhile, in literary composition, method of modifying is single,
The powdery paints prepared only is peeled off at antikathode and makes moderate progress in water boiling resistance performance, and its comprcssive strength, scratch resistance, anti-corrosive properties
Etc. aspect improved, accordingly, it would be desirable to existing technique and formula are improved.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the good montmorillonite intercalation of a kind of impact resistance gathers
Close modified epoxy based powder coatings and preparation method thereof.
The present invention is achieved by the following technical solutions:
The montmorillonite intercalation polymeric modification epoxy resin based powder coating that a kind of impact resistance is good, by the raw material system of following weight portion
Become: E-51 epoxy resin 60-62, montmorillonite 3-4, paraffin oil 5-7, n-butyl alcohol 8-9, graphite 8-10, molybdenum bisuphide 0.3-0.5,
Folium cinnamomi camphorae 20-22, ripe dehydrated potato powder 15-18, jade fiber 6-8, SBR emulsion 14-16, MTES
2.8-3.3, firming agent 3-5, pigment 7-9.
The manufacture method of the montmorillonite intercalation polymeric modification epoxy resin based powder coating that described a kind of impact resistance is good,
Comprise the following steps:
(1) montmorillonite is put in the dilute hydrochloric acid solution that mass fraction is 5-8% and stirs 3-5 hour at 50 DEG C-90 DEG C, filter,
Washing, to neutral, dried, is dispersed in EtOH-DI water solution, adds paraffin oil, molybdenum bisuphide 60 DEG C of stirred in water bath
2-4 hour, ultrasonic disperse 20-30 minute, sucking filtration, washing, it is dried under vacuum to constant weight, grinds, sieve to obtain modified nano montmorillonite；
(2) dried by Folium cinnamomi camphorae, attrition grinding crosses 200 mesh sieves, adds SBR emulsion, ripe dehydrated potato powder stirring and evenly mixing standing
12-14 hour, pelletize, sinter 20-30 minute in 800-1000 DEG C under nitrogen protection, add MTES, jade
Mineral wool grinds 20-30 minute to obtain composite modified filler；
(3) by E-51 epoxy resin, n-butyl alcohol stirring and evenly mixing, the modified nano montmorillonite of half quality is added, in 130-150 DEG C
Take out after lower reacting by heating 2-3 hour, obtain modified epoxy；
(4) modified epoxy prepared for step (3), step (2) material, the modified Nano of second half quality remaining are covered de-
Soil and other residual componentss put into stirring and evenly mixing in high mixer, melt extrude through double screw extruder, cool down pulverizing, cross 250-
300 mesh sieves, discharging.
The invention have the advantage that montmorillonite dilute hydrochloric acid solution acidification is carried out organically-modified by the present invention again, weaken
Adhesion between cheating engaging layer, makes interlayer lattice split, changes the highly polar of surface, make interlayer be changed into parent by hydrophilic
Oiliness, reduces its surface energy, makes interlamellar spacing expand, and specific surface area and absorbability dramatically increase, and finally it are added at twice,
Make montmorillonite steady by abundant intercalation and stripping, the lamella of stripping and epoxy resin formation chemical bond in the epoxy resin modification stage
Surely it is scattered in resin system, makes modified epoxy have superior high-temperature stability, hot storage stability and aging resistance
Property, improve water boiling resistance and the antikathode stripping performance of coating, the present invention goes back the composite modified filler of compatibility and other have simultaneously
Effect auxiliary agent, prepared powdery paints has the performances such as the tack of excellence, counter-bending and shock resistance.
