Embodiment 1
[0028] 182 parts of CX365-1 linseed oil modified long-oil alkyd (55% solid content), 16.2 parts of BENGEL818 easily dispersible organic bentonite, xylene, turpentine, and 200# solvent gasoline are mixed in an organic solvent ratio of 1:1:3 80 parts, after mixing evenly, disperse at a speed of 500r / min at a high speed until there are no visible particles, then add 9 parts of NDZ 201 coupling agent, stir for 5 to 10 minutes, and gradually mix 80 parts of 800 mesh iron phosphorus powder with different particle sizes, 80 parts of 500 mesh iron phosphorus powder, 163 parts of organic solvent mixed in the above ratio, 0.5 parts of 4% cobalt isooctanoate, 2 parts of 4% isooctanoate rare earth drier, and 4 parts of 10% calcium isooctanoate drier were added to the system in sequence within, and increase the rotating speed to 700r / min, disperse for 3 hours, and the weldable anticorrosion paint can be prepared.
[0029] Add an appropriate amount of supporting thinner to the prepared weld...
Embodiment 2
[0031] Weldable anticorrosive paint materials include 142.8 parts of PJ3546 soybean oil modified long oil alkyd (solid content 70%, oil content 61%) of Jiangmen Paint Factory, 100 parts of 800 mesh iron phosphorus powder, 100 parts of 1200 mesh iron phosphorus powder, 32.5 parts of wollastonite, 57 parts of xylene, 1.6 parts of KR-TTS coupling agent, 5 parts of VISCOGEL B4 bentonite anti-settling agent, 2 parts of 2% cobalt naphthenate drier, 3 parts of 2% manganese naphthenate, The preparation method is the same as that of Example 1.
[0032] The obtained paint was painted and tested according to the method of Example 1. The adhesion was first grade, the impact resistance reached 50cm, the surface resistance of the coating was 6Ω, and the paint film had no abnormalities in the salt spray test for 96 hours.
Embodiment 3
[0034] Add 8.7 parts of BENTONE SD-1 bentonite to 87 parts of xylene, stir and disperse evenly, then add 2.9 parts of industrial methanol, disperse at high speed, make it completely dispersed and activated to form a pre-gel for later use. Mix 142.8 parts of Yuanbang YP112-70 soybean oil modified alkyd resin (70% solid content), 3.5 parts of KR-38S coupling agent, 60 parts of 200# solvent gasoline, and 23 parts of D40 solvent with the prepared pregel , after stirring evenly, add 150 parts of 500% ferrophosphorus powder and 155 parts of 1200 1 part of zirconium isooctanoate and 2 parts of 4% calcium isooctanoate were dispersed for 1 hour to obtain the weldable anticorrosion paint.
[0035] The resulting paint was a gray-black liquid. Gained coating is coated according to example one method and detects, and after coating, paint film is smooth, without defects such as pinholes, orange peel, carries out damp heat resistance test and reaches 360 hours without abnormality, and its w...
