Abstract
The present invention provides alkali-resistant melting combined epoxy modified powder paint which is made from the components of the percentage by weight: 50 to 70% of resin (epoxy resin E12), 3 to 6% of solidifying agent (dicyandiamide), 1 to 5% of modifying agent (superfine TiO2) and balance of filling material (grammite). The coat of the paint of the present invention can resist corrosion of NaOH alkali solution or KOH alkali solution with the concentration of 40%.
Description
Technical field:
The present invention relates to a kind of coating, a kind of powder coating that contains Resins, epoxy.
Background technology:
Usually solve the problem of heavy corrosion protection, mainly contain following several method: surface modification, galvanic protection and the organic coating etc. of the optimization design of material structure, the redevelopment of material, material.
The organic coating guard technology is the anti-corrosion of metal means of a widespread use, and it has economy, characteristics such as quick, laborsaving, convenient, becomes one of most economical method of present control material corrosion.
Present many industries such as the water treatment pipeline of chemical industry, chemical fibre, the energy, electric power, metallurgy, nuclear power and military project etc. and the alkaline etching environment harshness of equipment, the requirement that domestic general protective system does not also reach above-mentioned industry, do not reach requirement as traditional line with rubber technology solidity to corrosion, and easily aging under corrosive environment; Though it is the coating of polyolefins has solidity to corrosion preferably, poor with bonding force, impermeabilisation, the scour resistance of metallic matrix; Though it is better that lining is moulded chemical stability, with the bonding force difference of matrix etc.
Summary of the invention:
The invention provides a kind of alkaline-resisting type smelting combined epoxy modified powder coating, this coating is by resin E12 Resins, epoxy, solidifying agent dicyandiamide, properties-correcting agent superfine Ti O
2Form with the filler wollastonite, its weight content is: resin 50～70%, solidifying agent 3～6%, properties-correcting agent 1～5% and filler surplus.
The solidifying agent of described alkaline-resisting type smelting combined epoxy modified powder coating can replace dicyandiamide with replacing dicyandiamide, ether Cuo or quinoline hydrazine.
The properties-correcting agent of described alkaline-resisting type smelting combined epoxy modified powder coating can be used CaCO
3Replace TiO
2
The filler of described alkaline-resisting type smelting combined epoxy modified powder coating can be used SiO, CaCO
3Or BaSO
4Replace wollastonite.
Above-mentioned resin, solidifying agent, filler and properties-correcting agent is placed in the ball mill by described prescription mixes and porphyrize.
The principal feature of alkaline-resisting type smelting combined epoxy modified powder coating provided by the invention:
(1), coating and basal body binding force be strong,
(2), coating self physical strength height,
(3), the impermeabilisation ability of coating is strong,
(4), the chemical stability of coating is good,
(5), the roughness low (little) of coatingsurface with the fluid frictional resistance,
(6), coating is nontoxic, satisfies food hygienic standard (can be used for food service industry).
The various performances of alkaline-resisting type smelting combined epoxy modified powder coating provided by the invention and the property comparison of common coating are as follows:
| Alkaline-resisting type smelting combined epoxy modified powder coating | Common coating | |
| Coating and basal body binding force | ＞90MPa | 10MPa |
| Coating self physical strength | ＞18J | 5J |
| The impermeabilisation ability of coating | ＜3.5% (reaching advanced world standards) | ＞5％ |
| The anti-NaOH of coating or KOH corrode | 40% (saturated) | ＜10％ |
The tensile strength of alkaline-resisting type smelting combined epoxy modified powder paint coatings is brought up to 110MPa, and the resistance to impact shock of coating is brought up to more than the 20J, and coating is soaked 1 year alternating-current impedance value in 60 ℃ 1% NaCl solution invariable, reaches 10
10Ω cm
2, and the permeability resistance of coating in 60 ℃ of distilled water below 3%.Above performance has all substantially exceeded the disclosed data of domestic and international similar technology, these preferably coating performance alkaline-resisting type smelting combined epoxy modified powder coating is used under more extensive and harsh heavy corrosion environment.
This coating with high combination property like this yet there are no both at home and abroad report to some extent.
Embodiment:
Embodiment 1

22% and filler wollastonite surplus.The performance of this alkaline-resisting type smelting combined epoxy modified powder coating is as follows:
Coating and basal body binding force: 100MPa,
Coating self physical strength: 18J,
The impermeabilisation ability of coating: 3.2%,
The anti-NaOH of coating or KOH corrode: 40% alkaline solution.
Embodiment 2
The prescription of alkaline-resisting type smelting combined epoxy modified powder coating is: E12 Resins, epoxy 60%, solidifying agent dicyandiamide 5%, properties-correcting agent superfine Ti O
23% and filler wollastonite surplus.The performance of this alkaline-resisting type smelting combined epoxy modified powder coating is as follows:
Coating and basal body binding force: 110MPa,
Coating self physical strength: 20J,
The impermeabilisation ability of coating: 3.0%,
The anti-NaOH of coating or KOH corrode: 40% alkaline solution.
The actual measurement antikathode is peeled off between 1.5-4mm, and much smaller than the standard that is used for the 8mm in the heavy corrosion protection abroad, this coating has certain little water permeability simultaneously, has guaranteed that coating has little electric current to pass through when galvanic protection, so can not produce cathode screen (CP) phenomenon.
Embodiment 3
