Description
Technical field
The present invention relates to technical field of coatings, specifically a kind of aqueous cathode electrophoresis dope and its manufacture craft.
Background technology
Electrophoretic coating is a kind of novel Environmental Protective Water-paint that is almost pollution-free, saving the energy, high usage, has film
The features such as smooth, water resistance and good chemical resistance.The mechanization and automation of such coating application industry easy to implement are suitble to use
In solve traditional application mode can not application application that is complex-shaped, having the special workpieces such as edge corner angle and hole, mainly answer
The anti-corrosion primer of automobile, motorcycle, industrial machinery and household electrical appliances is served as, the light industrys such as spring, slide fastener, spectacle frame are also widely used in
The decorative face of hardware applies.
Electrophoretic coating and coating process obtain commercial Application in the 1960s, have more than 50 years history so far.This
The inflammable toxic organic solvents that kind technology solves the problems, such as the reduction that people require or discharged when completely eliminating using coating, are adopted
Can carry out closed circulating system operation with cathode electrophoresis dope, utilization efficiency of coatings is more than 95%, this be other any coating and
Application mode is incomparable.Since the appearance of electrophoretic coating and application techniques, quick development is obtained, especially in vapour
It is even more to be widely used in terms of vehicle coating metal parts, almost 100% vehicle body primer painting all uses electrophoretic painting.
Electrophoretic coating is divided into as anode electrophoresis dope and cathode electrophoresis dope, based on the super requirement for anticorrosion to metalwork, PPG
It succeeded in developing cathode electrophoresis dope first in 1971, and requires high family in corrosion resistances such as Philip refrigerator, washing machines
Primer applications are used as on electrical appliance.1978, General Motors Corporation and Ford Motor Company were substantially by original Automobile
Body primer painting line is all switched to novel cathodic electrophoretic coating line.In the 1990s, the Car Body Painting life in the whole world
Producing line is substantially all switched to cathode electrodip painting paint line.
Since reform and opening-up, major coating production enterprise enters China one after another, such as U.S. PPG, Germany BASF, the U.S.
The well-known coating giants such as DuPont, Japan NipponPaint, Japan Kansai Paint establish research and development and production in China in succession
Base, and the cathode electricity of the automobile manufacturing companies such as one vapour of China Changchun, Shiyan Second Automobile Works, Shanghai Volkswagen, Wuhan Dragon Lord is captured rapidly
Coating of swimming supplies market.With the rapid development of China's economic, major foreign capitals cathode electrophoresis dope manufacturer obtains the advantage of expansion again,
And further expand production capacity one after another and dominate the market, as PPG produces 40000 tons of electrophoretic coating projects per year in 2011 in Zhangjiagang Yangtze
River Chemical spectrography formally completes, and is chased after in 2013 and throw 45,000,000 U.S. dollars for creating electrophoretic coating mixing center with full
The electrophoretic coating demand that foot increases increasingly；BASF then invests 90,000,000 Euros of constructions, one world-class scale in July, 2013
Production base to produce high performance resin and electrophoretic coating, and announces to go into operation in March, 2016.
At the same time, China has also actively developed the research of cathode electrophoresis dope in the enforcement period of the ninth five-year plan, as Changzhou coating is ground
Study carefully the units such as institute, Tianjin lighthouse paint and Chongqing " five or nine " institute and carried out a large amount of research and development, although being taken in 1986 years
Obtained preliminary achievement in research and be converted to industrial production, but it is insufficient due to appearance property the defects of, fail enter high-end automobile
Application market, can only hover stays in that light industry hardware etc. is low to require low-end market.In consideration of it, some domestic private enterprises are numerous and confused
The introduction work for carrying out cathode electrophoresis dope, as the double brave coating in Wuhan bought thick film the moon in CG100 in 1992 from German BASF
License is promoted in the production of pole electrophoretic coating, and is continued using so far；Hunan Xiang River coating is then joint with Japanese Kansai Paint
Hunan Xiangjiangguanxi Coating Co., Ltd is set up, is robbed by the technical formula resource of Japanese Kansai Paint and accounts for China closely
30% electrophoretic coating market；It is other to declare big, Dupont, South Korea Na Lu to introduce technology by from the U.S. if the Jin Litai of Shanghai
Cathode electrophoresis dope is promoted with exploitation.
According to incompletely statistics, aqueous cathode electrophoresis dope is still increased with nearly 7% rate in recent years.However it is domestic existing
Aqueous cathode electrophoresis dope has a single function, and constructing operation is complicated, and solidification temperature is high.
