Technical field
The invention belongs to special coating technical fields, and in particular to a kind of preparation side of extra long life polyureas anticorrosive paint
Method.
Technical background
Polyaspartic Ester-Based Coatings are a kind of aliphatic that polyureas field grows up in recent years, long response time, high resistance to
It waits, a kind of high performance coating, referred to as third generation polyureas.Polyaspartic ester is 100% solid part, and viscosity is low, can make
Standby large arch dam or solventless coatings have Diamond Search or extremely low VOC emission, and primary construction is achieved with required film thickness, greatly
Improve work efficiency, it is not only environmentally friendly but also energy saving.But spray polyurea is from first generation aromatic series to second generation rouge
Fat race arrives third generation Polyaspartic Polyurea again, respectively has excellent length but also all to deposit reaction speed too fast, need expensive
Spraying device special, suitable for heavy construction, need tie coat and solve adhesive force, pigment wetting and decorative shortcoming
Problem.The client for being difficult to be accustomed to the use of conventional coating receives.
Summary of the invention
For some problems existing for existing carbamide paint, the object of the present invention is to provide a kind of carbamide paint formulas, make
Can be constructed as conventional urethane dual-component coating with carbamide paint prepared by the formula, without dedicated spraying equipment and
