Description
Technical field
The present invention relates to powdery paints production and processing technical fields more particularly to a kind of polyester/epoxy mixed type powder to apply
Expect delustering agent and the polyester/epoxy mixed powder coating delustering agent in polyester/epoxy mixed powder coating delustring
Using.
Background technique
Mankind's activity exacerbates volatilization caused by environmental pollution, especially fossil energy and various manufacturing activities
Property organic compound (VOC) make environmental pressure increasingly severe, reduce air in VOC content, reduce energy consumption be coating row
One increasingly urgent problem of industry.Water paint, powdery paints, photocureable coating and high solid coating are as four big Novel rings
Guarantor's type coating becomes the direction of the following paint development.Wherein, powdery paints with its 3E (it is environmental protection, economical and efficiently,
Environmental, Economical, Effeciency), especially its low VOC emission liked deeply with it is more and more extensive
Using.
Powdery paints is divided into indoor and outdoor powdery paints, outdoor powdery paints generally use polyester/TGIC system and
Polyester/b- hydroxyalkyl amide (HAA) system；Indoor powdery paints then generally uses polyester/epoxy mixed type and pure epoxy type body
System.Wherein, polyester/epoxy mixed powder coating with its balanced comprehensive performance apply indoors in the most extensively, but this is poly-
The delustring of ester/epoxy hybrid architecture is always a problem.The delustring of past interior powdery paints, mainly using epoxy/disappear
The system of light curing agent is realized.The dulling and curing agent is mainly that Pyromellitic Acid (acid anhydride) and 2- benzylimidazoline are formed by salt,
Powdery paints is prepared for cured epoxy resin, while obtaining the effect of delustring.
Indoor powdery paints using the powdery paints of such dulling and curing agent preparation in addition to various gloss can be prepared
Except, the powdery paints prepared by it has many advantages, such as that flat appearance is smooth, powder storage stability is good, is extensively received by the market.
But there is also serious drawbacks for powdery paints prepared by such dulling and curing agent: preparing light-colored powder coating, especially
When white powder coating, film is easy to be influenced to generate by baking temperature or even common sunlight intensity (non-direct projection) more or less
Xanthochromia, i.e. yellowing.Product quality is thus seriously affected.Simultaneously as the delustering agent is used as epoxy hardener simultaneously again
It using, the reaction ratio with epoxy is about 1:10, i.e., need to consume a large amount of epoxies in powder formula processed, in the market, due to
, often there is the situation that supply falls short of demand, so that the formulation cost of powder processed is excessively high in epoxy price height enterprise.In addition, Pyromellitic Acid is made
The case where for minority's raw material, often being influenced by market supply, often being run out of goods, influence market supply.New indoor powder applies
Expect that the research and development of delustering agent become urgent problem to be solved.
People were to solve the above problems, once took number of ways, wherein solid carboxyl acrylic resin/dicyandiamide
Delustering agent is exactly a kind of good try.Solidify dicyandiamide using solid carboxyl acrylic resin/dicyandiamide dual cure systems,
The problem of can obtaining unglazed film effect (gloss is lower than 60 ° of 10%@), smooth coating, completely solving film xanthochromia.But
The case where defect using the technology is that powder storage stability is excessively poor, worst is that powdery paints stores only one week i.e.
Critical deterioration occurs.I.e. old problem is solved, but brings serious new problem, and being difficult to develop one kind always can overcome
The delustering agent of above-mentioned all defect.
