It is soft.
The present invention also provides the preparation methods of above-mentioned aqueous glass flake paint, include the following steps:
Step 1: epoxy resin, reactive diluent, wetting dispersing agent are added to the container by formula rate, it is stirred
Uniformly；
Step 2: auxiliary rheological agents are added in the mixture that the first step obtains, stir, is uniformly mixed；
Step 3: pigments and fillers are added in the mixture that second step obtains, stir, is uniformly mixed and obtains component A；
Step 5: in proportion mixing aqueous polyamide curing agent, water, high-speed stirred obtains B component after mixing；
Step 6: the component A that the 4th step obtains is mixed with the B component that the 5th step obtains, stir evenly to get product.
Further, the speed of agitator of second step is 400~600rpm, and mixing time is 0.5~1h；The stirring of third step
Revolving speed is 1500~2000rpm, and mixing time is 0.5~1h.
The advantages and positive effects of the present invention are: toughness of the present invention is good, solidification is quick, environmental protection, it can be used for marine worker
The outdoor anti-corrosion primer of the steels structures such as steel structure, bridge, pipeline and petroleum and petrochemical industry steel construction.The present invention is to surface treatment
Of less demanding, project amount is small, can reach requirement in rigidity and toughness in performance, even if coating also can be fast in the severe cold time
Speed solidification, meets production requirement, another importance is exactly in coating system used without containing the huge sum of money being harmful to the human body
Belong to.
