Abstract

The invention relates to a rusty antirust primer and mainly solves the problem that the construction quality is influenced by complicated sand-blasting and de-rusting construction processes of an existing rusty steel structure or pipeline. The rusty antirust primer consists of a component A and a component B, wherein the component A comprises the following components in percentage by weight: 37 percent of solid epoxy resin, 9 percent of anatase titanium dioxide, 1 percent of high-pigment carbon black, 15 percent of zinc phosphate, 12 percent of talcum powder, 4 percent of zinc powder, 4 percent of dimethylbenzene, 2 percent of n-butanol, 1 percent of organobentonite, 1 percent of an efficient wetting and dispersing agent, 1 percent of a dust-proof agent, 1 percent of a defoaming agent and 1 percent of a flatting agent; the component B comprises the following components in percentage by weight: 10 percent of a curing agent, 0.3 percent of dimethylbenzene and 0.7 percent of n-butanol. The rusty antirust primer has the benefits that the rusty antirust primer not only can be directly constructed on a rusty base material and form a protective passivation film through replacement reaction, but also can restrain the corrosion caused to steel and ferrous metal through active metal, so that the construction cost is reduced, and the working efficiency is improved.

Description

A kind of band rust rust-proofing primer
Technical field
The present invention relates to a kind of priming paint in paint field, especially a kind of band rust rust-proofing primer.
Background technology
Current domestic solvent type epoxy priming paint and polyurethane primer, anticorrosion year is limited to 15 years, but steel surface carries out derusting by sandblast before construction process requirement application, its quality should reach GB8923 specify in Sa2.5 level, surface answer non-corroding, free from dust, anhydrous mark, without greasy dirt.Encounter problems in construction as follows: (1) inefficiency, according to derusting by sandblast and two end two surface constructions, at least need more than 24 hours intervals.(2) operating environment is separately, Work places during derusting by sandblast will with spray paint, mopping operation separates, otherwise can affect antifouling paste construction effect.(3) consume human and material resources, time, increase working procedure, need professional and professional equipment to carry out derusting by sandblast.(4) cannot ensure construction quality, construction team, for trying to meet the deadline for the project, reduces derusting by sandblast working procedure to without rusty stain and the steel structure or pipeline lacking rusty stain, has a strong impact on quality.
Summary of the invention
The invention reside in overcome exist in background technology have the steel structure of rusty stain or the loaded down with trivial details problem affecting construction quality of pipeline derusting by sandblast working procedure, and provide a kind of band rust rust-proofing primer.This band rust rust-proofing primer, directly can construct, form protection passive film, suppress again the corrosion of iron and steel and ferrous metal by Active Metals, reduce construction cost, increase work efficiency by replacement(metathesis)reaction on band rust base material.
The present invention solves its problem and reaches by following technical scheme, this band rust rust-proofing primer, and its component and proportioning are as follows by weight percentage: be made up of component A and B component, in component A: solid epoxy 37%, anatase thpe white powder 9%, high-carbon black pigment 1%, zinc phosphate 15%, talcum powder 12%, zinc powder 4%, dimethylbenzene 4%, propyl carbinol 2%, organobentonite 1%, efficient wetting dispersing agent 1%, anti-settling agent 1%, defoamer 1%, flow agent 1%; In B component: solidifying agent 10%, dimethylbenzene 0.3%, propyl carbinol 0.7%.
Described component A and B component weight ratio are 8:1.
The principles of chemistry that this band rust rust-proofing primer utilizes are that iron rust main component is ferric oxide (Fe 2o 3), by unstable ferric ion (Fe + 3) become stable ferric oxide ion, easily oxidized iron (Fe) ion is protected, in formula, selects zinc phosphate and zinc powder, consumption and purposes as follows:
1, zinc phosphate: chemical formula: Zn 3(PO 4) 2, consumption 14%.Because of the rust-stabilising pigment that zinc phosphate is a kind of white non-toxic, the nontoxicity of new generation of antirust corrosive effect excellence, non-harmful rust-stabilising pigment, it effectively can substitute the traditional rust-stabilising pigment containing heavy metal lead, chromium, zinc phosphate gene has fine activity, complex compound can be generated with a lot of Action of Metal Ions, therefore there is good rust-proof effect.
Due to zinc phosphate Zn 3(PO 4) 2gene has fine activity, and can generate complex compound with a lot of metal, zinc phosphate and ferric ion have very strong complex ability, and zinc phosphate radical ion and iron anode react, and can be formed with tertiary iron phosphate FePO 4for the protective membrane of main body, this passive film is water insoluble, presents remarkable rustless property.
2, zinc powder: molecular formula: Zn, consumption 5%.Sacrificial anode protection, zinc powder comparatively iron ion is active, easily with oxygen generation oxidizing reaction in air, is made as anode by zinc powder, oxidizing reaction occurs and forms zinc oxide (ZnO), thus protects iron ion generation oxidizing reaction, 2Zn+2O 2↑=2ZnO.
Zinc oxide has outside certain tinting strength and opacifying power, has again antirust, anticorrosion and luminous function, and in addition, zinc oxide also has excellent ultraviolet screening ability, make its heavy industry antifouling paste anti-aging etc. in there is more outstanding characteristic.
The present invention can have following beneficial effect compared with above-mentioned background technology: this band becomes rusty the good rust transformation function of rust-proofing primer, capable of coating with rust, reduces derusting by sandblast working procedure; High-content metal zinc, has splendid galvanic protection effect, and the zinc oxide of formation can improve impact property, 50cm impulse detection, observes paint film flawless, wrinkle and peeling phenomenon.There is excellent wear resistance and weather resistance, strong adhesion, draw circle method sticking power grade and reach 1 grade.Have chemical reagent resistance widely, resistance to 10% sulphuric acid soln, resistance to 10% sodium hydroxide alkaline solution and resistance to sodium chloride salt >=50d, paint film non-scale does not come off.
Embodiment:
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
