Description
Technical field
The present invention relates to the corrosion protective lining composition, relate in particular to a kind of corrosion protective lining conduction screed-coat composition and method of making the same.
Background technology
At chemical industry equipment, the cement matrix surface of electric field dust removal installation, sea water desalting equipment etc. needs anticorrosive coating, and the bonding of cement matrix surface and corrosion protective lining is not fine, and because of the matrix poorly conductive, can not detect the defective of preservative coat with the electrical spark detector, so need between to form one and cement matrix and preservative coat bonding favorable conductive screed-coat.Multiple conduction self-leveling coating is arranged in the market, be embedded with conductive electrode (tinsel or wire netting etc.) in this coating, its effect is to derive the static that matrix surface produces, and the bond performance of it and corrosion protective lining (rubber lining and vinyl scale lining) is bad, can't be applied to this occasion.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides the corrosion protective lining screed-coat of cement matrix with conducting electricity from the levelling composition and method of making the same.Composition of the present invention can be from levelling, and and the antisepticise lining material bond performance good, and have good electrical conductivity and heatproof, erosion resistance, solvent resistance.
The present invention realizes like this: a kind of corrosion protective lining conduction screed-coat of cement matrix is used from the levelling composition, and it comprises following component:
Component a: epoxies Vinylite, 100 parts;
Components b: cobalt naphthenate, 1-3 part;
Amount of component b: flow agent, 1-3 part;
Component d: methylethyl ketone peroxide, 1-3 part;
Component e: conducting powder, 50-100 part;
Described umber is parts by weight.
Described Vinylite is the epoxies Vinylite.
Described flow agent is: a kind of in aerosil or the organobentonite.
Described conducting powder is one or more the mixture in metal-powder, carbon dust or the Graphite Powder 99.Described cobalt naphthenate is that commercially available concentration is 1% ~ 10% cobalt naphthenate.
The corrosion protective lining of described cement matrix conduction screed-coat is used from levelling preparation of compositions method, and described component a, b and c item are stirred in advance, adds component d when to be used and stirs at least 1 minute, stirs and becomes clay adding component e then.
But the clay blade coating of composition of the present invention preparation is to cement matrix, but Automatic Levelling (namely from levelling), air-dry after, having electroconductibility can be at its surface lining antiseptic rubber lining or vinyl scale clay.
To rubber lining, after the binding agent of lining parches (after general 48 hours), available electrical spark detector detects rubber lined defective (for example: pin hole, crackle, crack, impurity etc.).
To vinyl scale clay lining, solidify back (after general 48 hours) at clay, available electrical spark detector detects the defective (for example: pin hole, crackle, crack, impurity etc.) of vinyl scale clay lining.
If on cement matrix, do not add this conduction screed-coat, directly serve as a contrast rubber or clay, because there not being conductive layer, can not detect the defective of rubber lining and scale clay lining with the electrical spark detector, the little defective of this part can cause whole rot-resistant to lose efficacy.
Embodiment
The present invention is further illustrated below by embodiment: a kind of corrosion protective lining conduction screed-coat of cement matrix is used from the levelling composition, and it comprises following component:
