The accuracy and sensitivity of equipment, influences the use of equipment, or even causes scrapping for equipment.With the day of economic globalization process
Increasingly fast, Chinese Enterprise faces the huge commercial opportunities in home and abroad Liang Ge markets, and unprecedented hair is brought to China's manufacturing equipment industry
Exhibition opportunity, but corrosion of metal problem annoyings manufacturing Product processing, transport, storage etc. always.The economy that corrosion brings
Loss is considerable.According to data, the loss amount of money of the machinery industry of China in terms of corrosion accounts for the mechanical industry gross output value
7.2% or so.The direct, indirect loss that corrosion of metal brings is very important.
So-called rust is the mixture that metal surface generation oxide and hydroxide are acted on due to oxygen and water.Machinery exists
It is difficult not contacted with the oxygen in air, water or other Korrosionsmediums in operation and storage, these materials will be sent out in metal surface
Give birth to electrochemical corrosion and get rusty, to prevent corrosion from above material must be prevented to be contacted with metal.
In order to avoid corrosion, loss is reduced, employ various methods, wherein being protection metal system from antirust agent
One of most common method of product.But traditional antirust agent, particularly water miscible antirust agent often contains nitrite, dichromic acid
Salt etc. has the material of suitable murder by poisoning to human body.

Effect of the invention and effect
In scheme of the present invention, poly-aspartate is a kind of macromolecular water-soluble material, can in water
Metal ion forms a kind of metallo-chelate, and is attached to metal surface, prevents metal from continuing to corrode, while there is good life again
Thing degradability, it is friendly to natural environment and human body.
Fatty acyl sarcosines have good rust-preventing characteristic, at the same it is degradable in natural environment, and poly-aspartate is together
Doubled using rustless property with good cooperative effect, can be made.
Hydramine borate can form one layer of non-sacrificial diaphragm of densification in metal surface, especially have to ferrous metal
There is extraordinary rust-preventing characteristic.It is simultaneously environmentally friendly.
After alcohol ether phosphate can react with metal ion, layer protecting film is formed in metal surface, especially to aluminium
Alloy has extraordinary corrosion mitigating effect, biodegradable.
Additionally, in the present invention, low-carbon alcohols or alcohol ether Main Function are solubilising, make the component for being not readily dissolved in water more readily soluble
Yu Shuizhong.
BTA mainly provides the inhibition protection effect of non-ferrous metal particularly copper and its alloy.
Water is the carrier and solvent of each component.
After said components are miscible, with good cooperative effect, good rustless property is produced, while environmentally friendly.
