Description
Technical field
The present invention relates to a kind of soluble asphalt anticorrosive paint.
Background technology
Asphalt has good cohesiveness, ageing resistance and antiseptic power, is used as anti-corrosion material for a long time.With
In antiseptic project have the advantages that raw material be easy to get, it is cheap, be one of most widely used material in domestic and international antiseptic project.Gold
Loss is extremely serious caused by category corrosion, and it is to prevent one of main method of metal erosion to coat anticorrosive paint.
Most of anticorrosive paint is all that based on solvent based coating, it contains substantial amounts of organic volatile both at home and abroad at present
Thing, most of these organic volatiles are inflammable and explosive noxious material, not only pollute environment, waste the energy, and seriously endanger
Evil workmen's is healthy, and multiple harm is brought to the mankind and environment.
As people's environmental consciousness is gradually stepped up, environmental regulation is increasingly perfect, and the product structure of anticorrosive paint there occurs very
It is big to change：Traditional solvent based coating is just progressively substituted using water-based anticorrosive paint as the high-performance of representative, low contamination coating.Therefore
Energy-saving and environmental protection, efficient water-based anticorrosive paint have good development prospect.
Water-based metal anticorrosive coating experienced very long course to practical application from research and development, in development early stage, list
Component water-based metal anticorrosive coating can only be applied to the comparatively gentle field of environmental condition, such as replace solvent-borne alkyd resins
Make general purpose priming paint and finish paint.With the progress of coating technology, water-based metal anticorrosive coating has been gradually available for environment
The more severe place of condition, such as harsh industry and marine environment, especially bi-component aqueous epoxy resin, polyurethane coating
Appearance, water paint performance is reached the requirement of anticorrosive coating under severe rugged environment.Develop in succession both at home and abroad at present
The water-based metal anticorrosive coating series of products of the systems such as aqueous epoxy, aqueous polyurethane, water-based fluororesin.
Waterborne epoxy coatings existence and stability is poor, is unfavorable for storing and constructs, but also there is cost height, weatherability
The shortcomings of difference, slow drying speed, two-component complicated construction technique, it is subject to certain restrictions market.
Aqueous polyurethane coating most study is polyurethane/polyacrylate composite diffusion liquid system, but water resistance,
In place of construction still has some deficits with the performance in terms of application.
Water-based fluororesin coating, price is higher, is currently limited to use natural conditions are severe, decorative effect and uses the longevity
Life requires high, is difficult in the building of maintenance.
The content of the invention
The technical problems to be solved by the invention are the shortcomings for overcoming above prior art：Offer is a kind of to possess good
Stability, water resistance and weatherability, rate of drying is fast, environmentally friendly, efficient soluble asphalt anticorrosive paint.
The technical solution of the present invention is as follows：A kind of soluble asphalt anticorrosive paint, mainly by each of following parts by weight
Raw material is made：
65-90 parts of anti-corrosion emulsified asphalt；
5-12 parts of acrylic emulsion；
5-12 parts of styrene-butadiene latex；
0.1-0.5 parts of defoamer；
1-3 parts of coalescents；
0.5-1 parts of levelling agent；
Anti- 0.1-0.2 parts of flash rusting agent；
0.3-1 parts of thickener.
The preparation method of the soluble asphalt anticorrosive paint is as follows：First by acrylic emulsion, styrene-butadiene latex and anti-fermented bean curd
Change and be well mixed in pitch addition paint mixing tank, then add defoamer, coalescents, levelling agent, anti-flash rusting agent and thickener and stir
Mix 10-20 minutes and be well mixed, you can soluble asphalt anticorrosive paint is made；
Preferably, the coalescents are one or both of alcohol ester 12, propylene glycol.
Preferably, the levelling agent is organosilicon levelling agent or polyurethane levelling agent.
Preferably, the anti-flash rusting agent is the aqueous anti-flash rusting agent Raybo 60 of the auspicious precious production in the U.S..
The anti-corrosion emulsified asphalt is prepared from the following raw materials in parts by weight：
50-60 parts of 70# pitches；
0.5-1.5 parts of rosin soap；
0.5-1.5 parts of emulsifying agent；
0.1-0.5 parts of sodium hydroxide；
0.2-1 parts of defoamer；
0.2-0.8 parts of thickener；
40-50 parts of water.
The preparation method of the anti-corrosion emulsified asphalt is as follows：By rosin soap, emulsifying agent, sodium hydroxide, defoamer, thickener
Add in reactor A, stir with water, be heated to 50-70 DEG C it is standby；Meanwhile, 70# pitches are added in reactor B
Be heated to 100-120 DEG C it is standby；Finally the raw material in reactor A, B is mixed and passes through colloid mill high speed shear；
Preferably, described emulsifying agent be carboxylic acid type emulsifying agent, sulfonate type emulsifying agent, sodium sulfovinate emulsifier, it is non-from
One or more in subtype emulsifying agent.
Preferably, the defoamer is one or both of organic silicon defoamer, mineral oil antifoam agent.
Preferably, the thickener is polyurethane thickener, acrylate thickening agent, hydrophobically-modified alkali soluble surfactant
One or both of.
The beneficial effects of the invention are as follows：Asphalt has that cohesiveness is excellent, ageing resistance is good, impedance value is high and corrosion current
The low characteristic of density, and raw material be easy to get, it is cheap, as the raw material of anticorrosive paint, for a long time corrosion-resistant field in occupation of
Leading position.However, dropping down cold short feature due to itself there is heat, solvent-borne type anticorrosive paint is all made all the time, the present invention makes
With the asphalt emulsion of independent research, by asphalt emulsification technology, using water as solvent, solve pollution that organic solvent brings and
Acrylic emulsion and styrene-butadiene latex are dispersed in emulsified asphalt by the problem of cost is high, the present invention, in coating drying process,
Pitch is crosslinked the coating for forming network structure with condensate so that emulsified asphalt corrosion resistance coating can be improved further, while more
The weak points such as the poor water resistance of acrylic acid, permeable gas height are mended.The present invention is using anti-corrosion emulsified asphalt, aqueous acrylamide yogurt
Film forming matter is wanted based on liquid, butadiene-styrene rubber emulsion, function additive is added and prepares a kind of environmentally friendly, efficient water-based anticorrosive paint, with
Instead of traditional solvent-borne type anticorrosive paint, by asphalt emulsification technology, using water as solvent, production is solved and molten using opportunity
Environmental pollution and the wasting of resources and the injury to human body that agent volatile zone comes, while the problem of greatly reducing material cost.
Acrylic emulsion and styrene-butadiene latex are dispersed in emulsified asphalt by the present invention, by between pitch, acrylic acid, butadiene-styrene rubber
Crosslinked action, is greatly improved the properties of coating.Pitch has good cohesiveness, ageing resistance and anti-corrosion energy
Power, is allowed to overcome water paint poor water resistance this shortcoming, and carry with aqueous acrylic emulsion, the crosslinking of butadiene-styrene rubber latex composite compounding
The pliability and shock resistance of high film；Possess good stability, water resistance and weatherability, while also reducing aqueous anti-
The cost of rotten coating.
