Three, summary of the invention
The objective of the invention is provides weather resistant polyester powder coating of a kind of inorganic nano composite material modification and preparation method thereof at the deficiencies in the prior art, be characterized in existing powder coating, introducing inorganic nano composite material, to improve the weathering resistance of coating, improve hardness, sticking power, the shock strength of coating simultaneously.
The present inventor finds that nano zine oxide or silicon-dioxide have certain effect to the raising of polyester powder coating weathering resistance, but adds nano zine oxide or silica volume very little the time, can not obtain satisfied antiageing effect; And addition slightly for a long time, easily causes dope viscosity to rise again, and levelling property descends, thereby reduce the over-all properties of filming.Therefore, the present invention adopts three kinds of nano materials such as nano silicon, nano titanium oxide and nano zine oxide, with they carry out suitable surface treatment and compound after, add in the coating with suitable proportioning, bring into play their collaborative uvioresistant effect, improve the ageing resistance and the integrated performance index of coating greatly.
Purpose of the present invention is realized that by following technical measures wherein said raw material umber is parts by weight except that specified otherwise.
The prescription of the weather resistant polyester powder coating of inorganic nano composite material modification consists of:
50～70 parts in vibrin
4～8 parts in solidifying agent
17～30 parts of fillers
Nano composite material, particle diameter are 0.5～5.0 part of 10～100nm
2～10 parts of auxiliary agents
Nano composite material is at least a in silicon-dioxide, titanium dioxide and the zinc oxide.
Solidifying agent is triglycidyl isocyanurate (TGIC) or hydroxyalkyl amide.
Filler is at least a in titanium dioxide, talcum powder, lime carbonate, process white and/or the zinc sulfide white.
Auxiliary agent of the present invention comprises flow agent, corner hiding power properties-correcting agent, air release agent etc., these all are this those skilled in the art's technique known, can be used, to be these auxiliary agents do not have a negative impact to the realization and the obtaining of excellent results of the present invention of the object of the invention its precondition.
The preparation method of the weather resistant polyester powder coating of inorganic nano composite material modification:
1, gets 0.5～5 part of the nano composite material that particle diameter is 10～100nm;
2, nano composite material and 17～30 parts of fillers, 50～70 parts in vibrin, 4～8 parts in solidifying agent and the auxiliary agent with above-mentioned weighing mixes in high-speed mixer for 2～10 parts;
3, through the blended material, be transported to melting mixing in the screw extrusion press with feeder, by tabletting machine be pressed into thin slice, cooling, after crusher in crushing, be transported to that to carry out fine powder in the air classifying mill (ACM) broken, capture most of pulverized work in-process by cyclonic separator, after powder shifter is removed foreign material and coarse meal, obtain the powder coating finished product again, and pack.
The weather resistant polyester powder coating of the inorganic nano composite material modification of gained, its weathering resistance improves 100～200% than the unmodified polyester powder coating.
The present invention has the following advantages:
1, under the prerequisite that does not change original polyester powder coating production technique, by adding a spot of inorganic nano composite powder material, give full play to their collaborative uvioresistant effect, prepare polyester powder coating with high anti-ageing performance, the prepared nano-modified polyester powder coating that goes out, the coating that its weather-proof index does not more contain inorganic nano composite material has improved 100%～200%;
2, the polyester powder coating that more do not contain inorganic nano composite material such as other performance of coating such as hardness, sticking power, shock strength also is improved to some extent.
