Description
Technical field
The present invention relates to field of metal surface treatment technology, more particularly to a kind of little marine water of metal protection is prevented
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, and needs are suspended 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 various 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 it is 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
It is interior that the removing of original paint film clean and more complicated to some geometries part is processed more quick, will not be to base material
Any mechanical damage is caused, so it is 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, big to the body harm of workmen, 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 what is studied to paint stripper, various novel paint removers constantly gush
Now, alcohol ether type paint stripper and benzyl alcohol type paint stripper are exactly than more typical two class.
《The research of paint stripper used for ships》With benzyl alcohol as main solvent, ethanol is cosolvent, and carboxymethyl cellulose makees thickening
Agent, is prepared for water solublity 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
It is suitable with dichloromethane type paint stripper, then better than traditional paint stripper in terms of safety.
But watery paint remover still contains organic main solvent and nitration mixture accelerator in text, underlying metal material of painting is had
Very big corrosion failure to act on not environmentally, reduce the risk that its consumption has paint removal efficiency reduction again, therefore confirming efficiently
Also need to strengthen the anti-corrosion protection work of parent metal while depainting；Add carboxymethyl cellulose in text and make thickening agent, necessarily
Can improve paint stripper wall built-up in degree, but for vertical complicated metal surface when its wall built-up time it is 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.
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided a kind of little marine water of metal protection
Anti-corrosion compound paint stripper and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of little marine water anti-corrosion compound paint stripper of metal protection, is prepared by the raw materials in：Benzyl alcohol
31-33, N-Methyl pyrrolidone 6-8, dehydrated alcohol 7-9, vaseline 2-4, poly-aspartate 10-11, carbamide 0.4-0.7, silicon
Sour sodium 0.2-0.4, polrvinyl chloride 3-4, barbaloin 1-3, glutinous rice flour 12-13, sawdust 9-10, vinyltrimethoxy silane 2.8-
3.3rd, emulsifying agent 1.8-2.3, water 45-49 are made by oneself, described self-control emulsifying agent is by Arlacel-80, OP-10 and detergent alkylate sulphur
Sour sodium is compounded according to mass ratio 8: 2: 1.2.
A kind of manufacture method of the little marine water anti-corrosion compound paint stripper of described metal protection, including following step
Suddenly：
（1）Add the water of 1/10 mass to stir to dissolving in carbamide, add glutinous rice flour, barbaloin stirring 10-20 minutes, send into double
Screw extrusion 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 glutinous rice flour is obtained after change, dry, crushing；
（2）Sawdust drying was put in retort in 305-370 DEG C of charing process 30-40 minute, taking-up is cooled to 80-90 DEG C and adds
Enter polrvinyl chloride, vinyltrimethoxy silane ultrasonic grinding 10-15 minutes, drying is placed again in retort in 565-595
DEG C process 20-30 minutes, cooling add poly-aspartate, sodium silicate grinding 20-30 minutes, obtain modified sawdust powdered carbon；
（3）The water of residual mass is placed in reactor, benzyl alcohol, N-Methyl pyrrolidone stirring and evenly mixing is added, while stirring
Add dehydrated alcohol, vaseline to wait to be completely dissolved, add step（1）、（2）Material and other residual componentss stirring and evenly mixings, discharging.
It is an advantage of the invention that：The present invention will be benzyl alcohol, N-Methyl pyrrolidone compound after be main solvent, the phase with paint film
Dissolubility is good, causes macromole 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 glutinous rice flour as thickening binding agent, with paint
Film 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；Addition
Granular modified sawdust powdered carbon is that filling adsorption is strong, on the one hand extends good with coating surface swellability time of contact, on the other hand
Swelling rear depainting solution absorption can be come off in hole together, improve the removal efficiency of paint film, and the waste residue that depainting is produced can
Biodegradation, environmentally friendly efficiency high；Also add vaseline simultaneously and compound paint stripper obtained in other effective ingredient has solvent group
The characteristics of dividing stable, paint removal efficiency height and little metal protection.
