Metal effect polyester epoxy mixed type TEXTURE POWDER COATING, pure polyester-type TEXTURE POWDER COATING are widely used in five
The interior decorations products such as gold, furniture, electric appliance, antitheft door, magnalium section bar and outdoor durable device product.Due to the powder phase
Have for epoxy type preferably weather-proof, the purchasing of raw materials is convenient and cheap, therefore such powdery paints just exists once releasing
Domestic market is widely used and promotes.But instantly, client is higher and higher for weather-proof requirement, both the above powder
End is not met by service life and reaches 5-8, even more permanent requirement.Some plant powders in order to solve this problem,
One of weatherability transparent powder is sprayed on original decorative pattern powder again, but cross 2-3 metal patterns still to dim out or even not have
Have, because metal sludge ice is Cu-Zn alloy powder, aluminium silver powder, the time has grown oxidation by air nigrescence.In this way, because decoration and anti-corrosion are made
With, it has to coatings volatile organic compounds, powder brushes one times again, and the coating thickness of solvent based coating is generally in 20UM or so, to realize film

With decorative pattern art-type powder coatings when the fine arts type auxiliary agent that uses and other auxiliary materials and manufacture craft and construction requirement etc.
It is not exactly the same, even if using same fine arts type auxiliary agent, slightly changed on filler and other auxiliary materials and processing technology
Control is not stringent, it is possible to influence effect of decorative patterns, therefore the stability produced in batches is more difficult to control.And the generation of texture is with melting
The formation for melting the local flow difference of masking liquid is related, and the flowing of powdery paints is bigger, is more conducive to the formation of big lines, but line
The three-dimensional concave-convex sense on road reduces, therefore the factor of any local flow difference for changing melting masking liquid can all influence the shape of texture
Into.At present, the TGIC curing types polyester resin of domestic each polyester resin producer production can substantially meet smaller, thin scattered lines
The requirement of art-type powder coatings, but larger lines is not met by, such as wanting for the powdery paints such as middle flower, big-pattern, big wrinkle
It asks.Lines is smaller, easier formation, while the stereo concave-convex sense of lines is better.Lines is bigger, is less susceptible to be formed, while steady
Qualitative relatively low, lines concave-convex sense also tends to gently.This project is a kind of surfactant using the modified sludge ice agent of self-control.Through silicon
Oil modified acrylic ester class compound is made, and auxiliary agent has very narrow particle diameter distribution after strictly controlling, and there are many grains
Diameter specification can arbitrarily adjust decorative pattern size.CAB cellaburates is a kind of thixotropic agents, and for reconciling surface tension exists
Mainly when texture agent uses in powdery paints.Both the above auxiliary agent can be used alone, but cut both ways.Research staff takes two
Auxiliary agent coordinative role is planted to obtain the effect of decorative patterns of stable favorable reproducibility.
The selection of the weather-proof metallic pigments of the present invention.Most widely used in powdery paints is the gold such as aluminium pigment, Cu-Zn alloy powder
Belong to pigment.
