Description
Technical field
The present invention relates to a kind of antirusting paint, in particular to a kind of aqueous corrosion inhibition type Rust-resisting coating and its preparation side
Method.
Background technique
The construction of common anticorrosive paint, all has strict requirements to formation level, in order to protect steel not corroded, extends
Its service life, carrying out corrosion-proof coating to steel becomes a kind of economically and efficiently method.It is excellent corrosion-resistant in order to obtain
Performance must remove the iron rust on steel before coating completely, otherwise can lead to paint film and anti-corrosion due to the continuous expansion of iron rust
Poor effect, therefore, the processing of rust removing of iron rust is the important component of coating process, is played certainly to the success or failure of corrosion-proof coating
Qualitatively effect.But conventional method derusting adaptation range is narrow, energy consumption is high, noise is big, artificial rust cleaning efficiency is not high, dust floats

Puzzlement, and difficulty of construction is big, it is at high cost, and due derusting effect is often not achieved, it can not guarantee construction quality.Band rust is anti-
The appearance of rust coating solves this problem, low to basal plane requirement, can be coated directly on the surface of rusted metal, eliminate coating
The binding force of coating and matrix is also ensured while preceding a large amount of derusting work.Common band rust antirust bottom currently on the market
Paint, majority, which is added to, turns rust agent, and turns rust agent and further corrode in face of corrosive ions without any barrier effect, leads to it
Service life is short.Therefore, it needs to develop a kind of aqueous corrosion inhibition type Rust-resisting coating.
Sodium tripolyphosphate is a kind of amorphous water-soluble threadiness Quadrafos, is usually used in food, makees water retention agent, product
Quality improving agent, pH adjusting agent, metal-chelator, for the one kind for turning rust agent.Sodium molybdate is often used as corrosion inhibitor, is used as chromium
The dual function of the same clan with inhibition and turn rust of element, and compared to chromium, molybdenum element is more environmentally-friendly.8-hydroxyquinoline is insoluble
Be also known as quinolinol in the light yellow crystal of water, there is the anion ligand of the bis- coordination atoms of electron rich atom N, O, can and metal
Ion forms multiple tooth chelate, and neutral insoluble chelate can be formed with many metallic ion coordinations.
Aeroge is highly porous nano structural material, because it is with low-density, high porosity and high-specific surface area etc.

1 is the detection of the stability, film layer appearance and film adhesion of three kinds of coating.
As can be seen from the figure the impedance value of a group is minimum, especially low with b group and the comparison of c group, shows to be not added with any anti-corrosion
The antiseptic and rustproof ability of a group of antirust is poor, and a group has also appeared a weber impedance (45 ° of oblique lines) in low frequency range, shows that hitting occurs in coating
It wears, loses protective capability；The impedance value highest of c group, although there are also protective capability, resistance value or low c groups for b group, in conjunction with table
In data analysis, this is because sodium tripolyphosphate, sodium molybdate and 8-hydroxyquinoline, dispersion is uneven, causes to give full play to
Antiseptic and rustproof ability；And c group highest is still because of the stable dispersion of three kinds of fillers, also as the porous knot of cellulose base aeroge
The presence of structure increases the time that corrosive ions reach metal surface, increases the anti-corrosion ability of coating.
