Description

A kind of band rust anti-corrosive primer
Technical field
The present invention relates to a kind of priming paint in paint field, especially a kind of band rust anti-corrosive primer.
Background technology
Country's solvent type epoxy priming paint and polyurethane primer, are limited to 15 years, but construction process requirement application in anti-corrosion year at present Preceding steel surface carries out derusting by sandblasting, its quality should reach GB8923 provide in Sa2.5 levels, surface answer non-corroding, free from dust, Without water mark, without greasy dirt.Encountered problems in construction as follows:(1) inefficiency, according to derusting by sandblasting and the surface construction of two bottom two, extremely Need to be spaced for more than 24 hours less.(2) operating environment is separated, and Work places during derusting by sandblasting will be with spray painting, mopping operation point Open, otherwise can influence corrosion resistant coating construction effect.(3) consumption human and material resources, the time, increase working procedure, it is necessary to professional and Professional equipment carries out derusting by sandblasting.(4) construction quality can not be ensured, construction team is tries to meet the deadline for the project, to the steel without rusty stain and few rusty stain Structure or pipeline reduce derusting by sandblasting working procedure, have a strong impact on quality.
The content of the invention
The invention reside in overcoming, the steel structure for having rusty stain present in background technology or pipeline derusting by sandblasting working procedure are cumbersome The problem of influenceing construction quality, and a kind of band rust anti-corrosive primer is provided.Band rust anti-corrosive primer, you can on band rust base material directly Construction, forms protection passivating film by replacing reaction, can suppress the corrosion of steel and ferrous metal by Active Metals again, reduction is applied Work cost, improves operating efficiency.
The present invention, which solves its problem, to be reached by following technical solution, band rust anti-corrosive primer, its component and proportioning It is as follows by weight percentage:It is made up of component A and B component, in component A:Solid epoxy 37%, anatase thpe white powder 9%, High-carbon black pigment 1%, trbasic zinc phosphate 15%, talcum powder 12%, zinc powder 4%, dimethylbenzene 4%, n-butanol 2%, organobentonite 1%, efficient wetting dispersing agent 1%, anti-settling agent 1%, defoamer 1%, levelling agent 1%;In B component:Curing agent 10%, dimethylbenzene 0.3%, n-butanol 0.7%.
Described component A is 8 with B component weight ratio:1.
The principles of chemistry that band rust anti-corrosive primer is utilized are that iron rust main component is di-iron trioxide (Fe2O3), by shakiness Determine ferric ion (Fe+3) become stable oxidation iron ion, iron (Fe) ion being oxidized easily is protected, in formula From trbasic zinc phosphate and zinc powder, consumption and purposes are as follows:
1st, trbasic zinc phosphate:Chemical formula:Zn3(PO4)2, consumption 14%.Because trbasic zinc phosphate is a kind of rust resisting pigment of white non-toxic, it is Excellent non-toxic, the non-harmful rust resisting pigment of new generation of antirust corrosive effect, it can effectively substitute containing heavy metal lead, Traditional rust resisting pigment of chromium, trbasic zinc phosphate gene has fine activity, and complex compound, therefore tool can be generated with many Action of Metal Ions There is good rust-proof effect.
Due to trbasic zinc phosphate Zn3(PO4)2Gene has fine activity, can generate complex compound, trbasic zinc phosphate and three with many metals Valency iron ion has very strong complexing power, and trbasic zinc phosphate radical ion reacts with iron anode, can formed with ferric phosphate FePO4For main body Diaphragm, this passivating film is water insoluble, shows remarkable rustless property.
2nd, zinc powder:Molecular formula:Zn, consumption 5%.Sacrificial anode protection, zinc powder is active compared with iron ion, is easily sent out with oxygen in air Raw oxidation reaction, i.e., be made as anode by zinc powder, occurs oxidation reaction formation zinc oxide (ZnO), so as to protect iron ion Oxidation reaction, 2Zn+2O2↑=2ZnO.
Zinc oxide has outside certain tinting strength, tinting power and covering power, has antirust, anti-corrosion and luminous function again, in addition, zinc oxide Also there is excellent ultraviolet screening ability, make its heavy industry corrosion resistant coating it is anti-aging in terms of there is more prominent spy Property.
It is of the invention to be had the advantages that compared with above-mentioned background technology:The rust of band rust anti-corrosive primer well turns Change function, it is capable of coating with rust, reduce derusting by sandblasting working procedure;High content metal zinc, is acted on splendid cathodic protection, The zinc oxide of formation can improve impact property, 50cm impulse detections, observation paint film flawless, wrinkle and peeling phenomenon.Have Excellent wearability and durability, adhesive force is strong, and scratch adhesive force grade reaches 1 grade.With extensive chemical reagent resistance, Resistance to 10% sulfuric acid solution, resistance to 10% sodium hydroxide aqueous slkali and resistance to sodium chloride salt >=50d, paint film non-scale are not fallen off.
Embodiment:
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
