Formula and preparation of underwater construction anticorrosion primer
The component A comprises:
e44 epoxy resin 76 kg
4.2 kg of NX-2013 plasticizer
17.2 kg of mica powder
Modified bentonite anti-settling agent F8810.8 kg
1700.3 kg of wetting dispersant
Silicone antifoam BYK 3310.1 kg
0.8 kg of solvent-free coal tar pitch
B, component B:
1085 Special curing agent 9.9 kg
Aminosilane coupling agent BM 210.1 kg
The construction method comprises the following steps:
a component A: curing agent 100: 40
And (3) formula analysis:
e44 is solvent-free low-molecular epoxy resin with moderate viscosity (viscosity Pa S/25 ℃: 6-10), and the viscosity is too high or too low to be beneficial for underwater paint.
The NX-2013 plasticizer is an epoxy group-containing cashew nut shell oil modified epoxy resin diluent, has a good plasticizing effect, has small influence on the chemical corrosion resistance of a system, and is not easy to cause the problem of plasticizer migration.
3. The mica powder is selected to enhance the corrosion resistance of the system, and as the mica powder is a flaky filler, a labyrinth effect is generated in a paint film layer, so that the permeability resistance to corrosion medium is improved by times.
4.881F-is an efficient anti-settling agent and is also a consistency regulator, so that the consistency of the paint system is in a more ideal range.
5.170 is a filler wetting dispersant with high cost performance.
BYK331 is an efficient defoamer to prevent paint from generating bubbles during production and construction.
7. The solvent-free coal tar can be used as a toner which is easy to disperse and can also be used as an anticorrosion reinforcing agent, and the coal tar pitch has extremely strong hydrophobicity.
8. The curing agent 1085 is selected because the epoxy adhesive prepared by the common epoxy curing agent has an unsatisfactory use effect, can only be used for bonding on the surface of a dry adherend, if the curing agent is used in water or a surface wetting agent or underwater, the bonding strength is reduced sharply, and some bonding cannot be performed, and when the common underwater curing agent is used underwater, the bonding strength is reduced by at least more than half compared with the bonding strength used in a dry environment, so that the phenomenon of whitening occurs.
The 1085 type completely underwater strong type epoxy resin curing agent is a water-increasing curing agent which does not react with water and adheres by reacting with epoxy resin while removing water from an adherend when adhering it. The adhesive can be bonded in a humid environment and underwater, and the bonding strength is almost one hundred percent of the retention rate compared with the bonding strength in a dry environment.
