The good compatibility is had with oleum lini alkyd resin.Alkyd resin is mixed with the arbitrary proportion that 1:1～3:1 is interval with modified resin
After conjunction, the paint film prepared, rate of drying is fast, paint film light, hard high good.
Utilizing the good substrate wettability energy that alkyd resin itself has, prepared coating has good with ground
Adhesive strength, have employed modified resin simultaneously, has hardness of paint film high, water-tolerant, the feature of good endurance, coating of the present invention
Have both the above properties of materials concurrently, make the coating of preparation have good antiseptic property.
Using organic modified bentonite and organophosphorus ester is the auxiliary rheological agents of coating, and it has the strongest with modified alkyd resin
Hydrogen bond action, show as under static conditions, resin liquid presents frozen glue shape, and after applying certain shearing force, its viscosity
Decline rapidly, embody excellent thixotropic property.Wherein, in modified alkyd resin the ratio of alkyd resin and modified resin at 1:1
～this thixotropic effects is best in 2:1 interval, so that the alkyd paint of preparation has good thixotropic effects, meet thick-film and be coated with
The demand of dress.
The coating of the present invention can use conventional coating material production mode, will be ground to thin after formula each component mix homogeneously
Degree regulates viscosity after meeting the requirements, and filters and packages and obtains coating products, it is possible to use described thick-film modification alcohol in summary of the invention
The preparation method of acid coating.
The present invention be a kind of can the modified alkyd paint of thick-film construction, its preparation technology is easy, has good anticorrosion
Performance, product salt spray resistance can reach more than 1000h, and the corrosive medium of atmospheric region is had excellent insulating.Meanwhile, this painting
Material has low viscosity, the feature of high thickness, and single track film forming thickness is up to 100～150 μm, and rate of drying is fast, at 25 ± 2 DEG C
Under, i.e. can reach in 12h and do solid work, consequently facilitating the carrying out of rear road working procedure, construction period can be shortened, save construction cost.
Meet the needs of the engineer applied such as boats and ships, steel construction, pipelines and petrochemical pipelines.
