Description
Technical field
The present invention relates to a kind of fluoroacrylic resin matrix material and preparation method thereof, especially a kind of epoxy resin and SiO
2modified fluoride-containing acrylic resin compound material and preparation method thereof.
Background technology
In recent years, along with improving constantly of people's living standard, the demand of domestic air conditioning increases rapidly.China's domestic air conditioning annual turnover in 2013 is always with 12% speed increment.But the interchanger set up by air-conditioning filtering is a vitals of air-conditioning, when refrigerant fluid is by the copper pipe that is tightly connected with cooling fin, airflow then passes through along between the aluminium foil cooling fin perpendicular to this flow direction.Because the temperature of refrigerant fluid is lower than the temperature of air, when thus flowing into aluminium foil cooling fin higher than the air of refrigerant fluid temperature, the relative humidity between cooling fin will be made to raise, and the moisture condensation in air is adsorbed on its condense on surfaces and becomes the globule.Therefore, bacterium dust etc. will be adsorbed on aluminium foil surface, according to bacteria total amount on the Center for Disease Control logist heat sink of air conditioner of Shanghai up to 1.6 × 10
6individual/cm
2, also can detect a large amount of legionella, bacillus cereus, mould, the pathogenic bacterium such as streptococcus aureus.And " water bridge ", " white powder ", " peculiar smell " etc. can be formed.These problems can cause the refrigerating duty of interchanger to reduce, and energy consumption and noise increase, and the decrease in efficiency of conditioning unit, work-ing life declines greatly, and greatly can pollute indoor environment, affects HUMAN HEALTH.Therefore the process of air conditioner aluminium foil surface super hydrophobic becomes hot issue.According to the prediction of coating industry association of Guangdong Province, air conditioner aluminium foil carries out super hydrophobic coating process and becomes main flow, market in 2012 divide reach 1.3 ten thousand tons and with about 2% speed increment.
Current American-European-Japanese grade is dealt into country abroad and mainly adopts two kinds of methods to carry out anticorrosion WATER REPELLENT to air conditioner aluminium foil surface: (1) is coated with one deck hydrophobic coating (mainly organic super hydrophobic coating) at aluminium foil surface, make water droplet form the globule that is spherical or spheroidal at coatingsurface, tumble down voluntarily.(2) be coated with one deck hydrophilic coating (mainly inorganic super hydrophilic coating) at aluminium foil surface, form hydrophilic film, make water droplet at the rapid drawout of coatingsurface and flow away.The research of external super hydrophobic coating occupies Chinese market greatly, and Imported Aluminium pool super hydrophobic coating price is extremely expensive, up to 7000-10000 unit/kg.Therefore, Devoting Major Efforts To Developing and the development of application air conditioner aluminium foil super hydrophobic coating on China's air conditioner industry have great importance and affect.
The super hydrophobic coating of current domestic development substantially improves the predicament of capturing Chinese market abroad, but hydrophobic effect meets the requirements of simultaneously, layer-to-layer adhesion effect between hydrophobic coating and air conditioner aluminium foil is undesirable, and this just occurs that coating is short for work-ing life, the phenomenon of waste of material.
