Under standard test condition, saline sook concentration is certain, and the stainless time is longer, illustrates that rust-proof effect is better, conversely, effect is poorer；
Embodiment 1 arrives embodiment 10, and the stainless time more than 25 days, changes matching somebody with somebody for each raw material composition in severe antirusting paint respectively
Than having different degrees of influence to the rustless property of material, in modified Na-LTA/SSZ-13 nano materials, acrylic resin
It is 3 with modified sodium silicate sand quality proportioning：1：2, when other dispensing dosages are fixed, rust-proof effect is best；It is it is worth noting that real
Apply example 11 and add modified bauxite, rust-proof effect is greatly improved, reached 125 days, illustrates modified bauxite to filling-material structure
Rustless property have more preferable optimization function；Reference examples 1 to reference examples 4 change modified Na-LTA/SSZ-13 nano materials and prepared
Sodium nitrate and molecular sieve proportioning and oxidant potassium permanganate dosage, rust-proof effect is decreased obviously, and illustrates sodium nitrate and oxidant
Dosage produces material impact to the modified of molecular screen material；Reference examples 5 change the acid concentration of composite molecular screen washing to reference examples 6
And component, effect is also bad, illustrates that cleaning solution acidity is modified to molecular screen material and plays an important role；Reference examples 7 and example 9 change
The proportioning of water glass sand modified raw material, insulation effect substantially reduce, and illustrate sepiolite, carbon black and aluminum oxide dosage to filling-material structure
Composite modified influence it is very big；To example 10, the dosage of tetrabutyl titanate is increased, effect is still bad, illustrates tetrabutyl titanate
The rust-preventing characteristic of coating can excessively be influenceed；Therefore the forms poisoning antirusting paint prepared using the present invention has good antirust to imitate
Fruit.
