Abstract
The present invention relates to the preparation methods of a kind of high durable containing glass fibre and clay mineral, anticorrosion polyester type powder paint, by the way that terminal carboxyl polyester, GMA class acrylic resin, unsaturated polyester resin, triglycidyl isocyanurate (TGIC) to be introduced into powdery paints cross-linked structure simultaneously, squeezed out by screw mixes, airflow milling obtains micron-sized powder product after crushing.The present invention can guarantee lustrous surface etc. other have excellent performance under conditions of realize effective promotion of weather resistance, Corrosion Protection, impact property, polyester/TGIC type properties of powder without glass, clay relative to regular convention formula is more excellent, low in cost, easily operated control.
Description
Technical field:
The invention belongs to macromolecule high durables, anticorrosion type coatings art, and in particular to one kind can pass through polyester, solidification
The components such as agent, catalyst compounding come adjust such as glossiness, high durable, anticorrosive property, the every surface property of self-healing it is poly-
Ester type powdery paints.
Background technique:
It is more and more different types of as the competing product of substituted type as unfriendly property of the solvent based coating to environment is aggravated
Powdery paints just gradually replaces solvent based coating due to VOC free and the advantages of easily recycling, is with pure polyester-type, epoxy/polyester type
The powdery paints of representative also occupies more and more important position in the fields such as household, industry.
However, identical as traditional solvent based coating, even powdery paints is also faced with and is easy quilt in some scenarios
It damages, be corroded, the use hidden danger that the service life is shorter, to injure the normal fortune at the even crucial motor-driven position of inner layer material
Row.The application of different field all proposes higher requirement, more and more people to the weatherability of powdery paints and corrosion resistance
Also attempt addition filler, improve powder structure, prepared using bio-based materials (such as bamboo, straw, fiber crops, coir fibre) it is compound
The methods of polyester material carrys out the functionality of reinforcing material, however these methods more or less all can be with the strong of expendable material itself
Degree, impact property etc. are cost.
The present invention utilizes multiple types and cheap saturation/curable unsaturated polyester network structure, is aided with a small amount of third
Olefin(e) acid resin " cold spelling " recycles the clay minerals such as highly pure glass fiber powder and mica, montmorillonite, kaolin filler poly- to assign
The more sound lasting performance of ester type powdery paints has both coating including high intensity, certainly
The multiple performances such as repair function avoid the awkward field of the powdery paints such as polyester " splitting once hitting " on the basis of guaranteeing strength of coating
Scape.
Summary of the invention:
The purpose of the present invention is to provide a kind of surface high durable and the excellent powdered coating materials of Corrosion Protection, are based on
Powdery paints advanced optimizes its various functions type advantage because of solvent-free environmental protection and the advantages such as powder rate of recovery height.
High durable of the present invention and etch-proof polyester-type powdered coating materials by following components by weight preparation and
At:
In one embodiment, the terminal carboxyl polyester acid value is 32~38mgKOH/g, and viscosity is larger, when gelatinization
Between it is long, flow leveling is slightly poor, but high mechanical strength, is chiefly used in open air.Its preferred mass part is 370 parts.
In another embodiment, universal GMA class acrylic resin high durable, and be conducive to gloss raising, ring
Oxygen equivalent is 500 or so.Its preferred mass part is 10 parts.
In another embodiment, the unsaturated polyester resin is 196# type neighbour benzenoid universal unsaturated-resin,
For 1,3- isobenzofurandione and 2,5- furasndione, 2, the polymer of 2 '-oxo di-methylcarbinols and 1,2-PD.Its quality
Part is 20 parts.
In another embodiment, the peroxidized t-butyl perbenzoate is common unsaturated polyester solidifying agent/initiation
Agent is preferably 0.2 parts by weight.
In another embodiment, the catalytic promoter is 2-methylimidazole, zinc acetylacetonate, tetrabutyl phosphonium bromide
One of ammonium, triethylbenzene base bromide phosphine.The zinc acetylacetonate that preferred weight part is 1.
In yet another embodiment, the titanium dioxide is R type, i.e. rutile-type, and ingredient is purer, serves not only as face
Material is had excellent performance, and can be acted on shielding ultraviolet rays.Its mass parts is 100 parts.
In yet another embodiment, described polyethylene wax preferred mass part is 15 parts.
In yet another embodiment, described barium sulfate preferred mass part is 55 parts.
In yet another embodiment, the glass fiber powder is the fiber powder of 800 mesh of high-purity, and preferred mass part is 1
Part.The clay mineral ingredient includes two kinds of montmorillonite, kaolin ingredients, and mass parts are 20 parts of montmorillonite, 10 parts of kaolinite
Soil.
The utility model has the advantages that
The present invention solves the problems, such as that general powdery paints plate face weatherability, anticorrosive property are bad mainly from two angles:
Firstly, the gas barrier effect and dimensional stability that pass through ultraviolet screener effect, the montmorillonite of R type titanium dioxide
The interference of equal physical layers isolation external condition；Along with a small amount of kaolinic addition, flat nature can effectively obstruct water
Point or acid & alkali liquid infiltration so that film abrasion resistance and resistance tocrocking are improved, in addition to this, kaolinic chemistry is lazy
Property is stronger, and optical axis of crystal angle is small, and the degree of order of crystal arrangement is higher, also can shielded segment ultraviolet light.The addition of the above filler is all
It reduces material plate face and may cause the chance that the condition of corrosion contacts with the external world, also improve the corrosion resistant of plate face in a way
Corrosion；In addition, itself from material, the cross-linked structure between saturation/unsaturated polyester (UP)/a small amount of acrylate forms coating
Very fine and close three-dimensional net structure, and the presence of unsaturated polyester (UP) and the presence meeting of reinforcing material glass be so that coating system
Intensity is high, it is heat-resist, with excellent resistance to chemical corrosion and electrical property, extraneous strong acid-base environment or strong sunlight are also difficult
With infiltration.The presence of a small amount of acrylate is less prone to local stripping but also coating and coated article surface are contiguously even closer
From, fall off phenomena such as.
Again due in system there are more polyethylene wax and facilitate levelling effect the kaolin with flat nature
The presence of equal ingredients, in addition coat inside contains a large amount of ester group, always along with catalyst such as zinc acetylacetonate etc.
In the presence of reversible ester group exchange reaction also has comparable probability that can occur, even micro when local damage occurs for plate face
Wax ingredient and kaolin to incremental sliding at dent can also obtain certain repairing effect over time, and
And this phenomenon can become particularly evident when giving heating condition, including levelling process and reversible key exchange reaction,
The two can obtain certain repairing effect.
To sum up, the resistance to of the polyester powder coating is effectively improved by the complication of cross-linked structure and the addition of a variety of fillers
It waits, resistance to corrosion.
Detailed description of the invention:
Fig. 1-5 is corrosion condition of the embodiment 1-5 sample after 300h salt spray test.
Specific embodiment:
Following embodiment the present invention is furture elucidated content, but it is not limited to the scope of the present invention.
Embodiment 1:
It is a kind of using glass fibre and clay mineral as the high durable of filler and etch-proof polyester/TGIC type powder applies
