Description
Technical field
The present invention relates to field of metal surface treatment technology, more particularly to a kind of novel low-toxicity high adsorption oceangoing ship is with aqueous anti-
Rotten compound paint stripper and preparation method thereof.
Background technology
Generally, ship's navigation 2-3, hull paint film will be subject to erosion and the mechanical damage of various corrosive mediums
Destruction causes paint film to damage, aging, needs to suspend to lie up and carry out necessary maintenance.In maintenance process, it is necessary to thoroughly remove
Paint film originally carries out again secondary application.There are multiple methods to can be used to remove old paint film, such as mechanical removal method, flame burns and loses
Method and paint stripper method etc., in these methods, paint stripper method is one of most-often used method because it does not need larger
Man power and material, can be in the short time simply by series of physical, chemical processes such as dissolving, infiltration, swelling, stripping and reactions
Interior part clean and more complicated to some geometries for the removing of original paint film is processed more quick, will not be to base material
Any mechanical damage is caused, so more time saving and energy saving during secondary application.
Traditional paint stripper is generally methene chloride such as dichloromethane with solvent.But methene chloride typically has very
High volatility and toxicity, environmental pollution are big, and the surface treatment of depainting part is more difficult, and the body harm to workmen is big, therefore
It has been strictly limited use.With the development in epoch, the environmental consciousness of people is more and more stronger, develops efficient, environmentally friendly
Paint stripper become paint stripper development direction.Increasingly deep with studied to paint stripper, various novel paint removers constantly gush
Now, alcohol ether type paint stripper and phenmethylol type paint stripper are exactly than more typical two class.
《The research of paint stripper used for ships》With phenmethylol as main solvent, ethanol is cosolvent, and carboxymethylcellulose calcium makees thickening
Agent, is prepared for water-soluble paint stripper used for ships.Novel paint remover is taken off to different paint films from traditional paint stripper by national standard
Paint effect is compared, and is as a result proved, the paint removing effect of the paint stripper is better than traditional alcohol ether type, thermokalite type paint stripper, and
Suitable with dichloromethane type paint stripper, then better than traditional paint stripper in terms of security.
But in text there be still containing organic main solvent and nitration mixture accelerator to underlying metal material of painting watery paint remover
Very big corrosion failure to act on not environmentally, reduce the risk that its consumption has paint removal efficiency reduction again, therefore confirming efficiently
The anti-corrosion protection work for strengthening parent metal is also needed to while depainting；Add carboxymethylcellulose calcium in text and make thickener, necessarily
Can improve paint stripper wall built-up in degree, but for vertical plane complicated metal surface when its wall built-up time short, make paint stripper
Short with old paint film time of contact, paint removal efficiency is low, limits the range of application of paint stripper, additionally, the sludge that chemical paint removal is produced
If shape material is dealt with improperly in collection, storage, transport and disposal process, immeasurable harm also can be caused to environment.Cause
This, the high-efficiency environment friendly anti-corrosion water-base depainting agent for developing low volatility is very necessary.
Content of the invention
The object of the invention is exactly the defect in order to make up prior art, there is provided a kind of novel low-toxicity high adsorption oceangoing ship is with aqueous
Anti-corrosion compound paint stripper and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of novel low-toxicity high adsorption oceangoing ship water-repellent preservation compound paint stripper, is prepared by the raw materials in：Phenmethylol
35-36,1-METHYLPYRROLIDONE 4-5, absolute ethyl alcohol 5.8-6.8, citric acid 6-8, calcium mahogany sulfonate 0.2-0.4, acetate fiber
Plain 0.5-0.7, poly-epoxy succinic acid 2.1-2.4, waste sludge from paper mill 4-6, water hyacinth 7-9, cassia oil 3-4, shitosan 0.3-0.5,
Wheaten starch 11-12, phenyl triethoxysilane 2.4-2.9, self-control emulsifying agent 1.4-1.9, water 47-50, described self-control are newborn
Agent is to compound Arlacel-80, OP-10 and neopelex according to mass ratio 8: 2: 1.2.
A kind of preparation method of the described novel low-toxicity high adsorption oceangoing ship with water-repellent preservation compound paint stripper, including following step
Suddenly：
（1）The water that citric acid adds 1/10 mass is stirred and evenly mixed, wheaten starch, shitosan stirring 10-20 minutes is added, is sent into
Double helix exrusion bulking machine, in 7 × 105At Pa and 125-140 DEG C, extruded by the pore of a diameter of 0.1-0.8mm, carry out pre- paste
Pre-gelatinized wheaten starch is obtained after change, dry, crushing；
（2）Waste sludge from paper mill, water hyacinth are dried and is put in retort in 330-430 DEG C of charing process 30-40 minute, take out cooling
To 80-90 DEG C of addition phenyl triethoxysilane ultrasonic grinding 10-15 minute, dry and be placed again in retort in 580-650
DEG C process 20-30 minutes, cooling add cassia oil, calcium mahogany sulfonate grinding 20-30 minutes, obtain modified compound powdered carbon；
（3）The water of residual mass is placed in reactor, adds phenmethylol, 1-METHYLPYRROLIDONE to stir and evenly mix, while stirring
Add absolute ethyl alcohol, poly-epoxy succinic acid to wait to be completely dissolved, add cellulose acetate, step（1）、（2）Material and other residues
Composition is stirred and evenly mixed, discharging.
It is an advantage of the invention that：The present invention will be compound to phenmethylol, 1-METHYLPYRROLIDONE after be main solvent, the phase with paint film
Dissolubility is good, causes macromolecular volume to increase, produces internal stress, paint film and the adhesive force of ground is reduced and is departed from；With anhydrous second
Alcohol is cosolvent, can accordingly reduce the consumption of main solvent, reduces cost；Using pre-gelatinized wheaten starch as thickening binding agent, with
Coating surface is firmly bonded that wall built-up is good and rapid-drying properties are good, can depart from rapidly metal surface, reduces to corrosion of metal；Add
The compound powdered carbon of particulate modified molybdenum is that filling adsorption is strong, on the one hand extends, the opposing party good with coating surface time of contact swellability
Swelling rear depainting solution absorption can be come off in hole by face together, improve the removal efficiency of paint film, and the waste residue that depainting is produced
Biodegradable, environmental protection efficiency high；Also add cassia oil simultaneously and compound paint stripper volatility be low obtained in other active ingredients,
Low toxicity, to metallic matrix safety, quick to operating personnel or environmentally friendly, easy construction, the high depainting performance of adsorptivity is splendid.
