Abstract
The invention discloses a water-based anticorrosive composite paint remover for a ship having a deodorizing function. The paint remover is prepared from the following raw materials in parts by weight: 34-36 parts of benzyl alcohol, 4-5 parts of N-methylpyrrolidone, 4-6 parts of anhydrous ethanol, 0.5-0.7 part of ethyl cellulose, 0.2-0.4 part of urotropine, 11-12 parts of etidronic acid, 3-5 parts of vanilla oil, 0.4-0.6 part of tea polyphenol, 12-14 parts of chestnut shell, 12-14 parts of peanut isolated protein powder, 2.3-2.5 parts of vinyltrimethoxysilane, 0.3-0.5 part of sodium tripolyphosphate, 1.6-1.8 parts of self-made emulsifier and 44-46 parts of water. By compounding the benzyl alcohol and the N-methylpyrrolidone to serve as main solvent, using the anhydrous ethanol as cosolvent, using the pregelatinized peanut isolated protein powder as a thickening adhesive, using the granular modified chestnut shell carbon powder as a filler to achieve high adsorptivity, and further adding the vanilla oil and other effective components, the prepared composite paint remover has an obvious deodorizing effect and a high paint removing efficiency.
Description
Technical field
The present invention relates to field of metal surface treatment technology, more particularly, to a kind of marine water with deodorization functions 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 leads to paint film to damage, aging, needs to suspend to lie up and carries out necessary maintenance.It is necessary to thorough remove in maintenance process
Paint film originally carries out again secondary application.Multiple methods are had to can be used to remove old paint film, such as mechanical removal method, flame burn 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, simply by series of physicals such as dissolving, infiltration, swelling, stripping and reactions, chemical process can be in the short time
Interior clean and more complicated to some geometries part process of original paint film removing is more quick, will not be to base material
Cause any mechanical damage, 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 is 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, and exploitation is efficient, environmentally friendly
Paint stripper become paint stripper development direction.Increasingly deep with study 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 classes.
《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.By national standard, novel paint remover is taken off to different paint films from traditional paint stripper
Paint effect compares, and result proves, the paint removing effect of this paint stripper is better than traditional alcohol ether type, thermokalite type paint stripper, and
Suitable with dichloromethane type paint stripper, then it is better than traditional paint stripper in terms of safety.
But watery paint remover still contains organic main solvent and nitration mixture accelerator in literary composition, japanning underlying metal material 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 literary composition and make thickening agent, necessarily
Paint stripper wall built-up can be improved on degree, but for vertical complicated metal surface when its wall built-up time short, make paint stripper
Short for time of contact with old paint film, paint removal efficiency is low, limits the range of application of paint stripper, additionally, the mud that chemical paint removal produces
If shape material is dealt with improperly in collection, storage, transport and disposal process, also environment can be caused with immeasurable harm.Cause
This, the anti-corrosion water-base depainting agent of high-efficiency environment friendly 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, provides a kind of marine water with deodorization functions
Anti-corrosion compound paint stripper and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of anti-corrosion compound paint stripper of marine water with deodorization functions, is prepared by the raw materials in：Benzyl alcohol

Trimethoxy silane 2.3-2.5, sodium tripolyphosphate 0.3-0.5, self-control emulsifying agent 1.6-1.8, water 44-46, described self-control is newborn
Agent is to be compounded Arlacel-80, OP-10 and dodecylbenzene sodium sulfonate according to mass ratio 8: 2: 1.2.
A kind of manufacture method of described anti-corrosion compound paint stripper of marine water with deodorization functions, walks including following
Suddenly：
（1）The water that tea polyphenols are added 1/10 mass stirs to dissolving, adds separating protein powder of peanut, hexamethylenamine stirring 10-
20 minutes, send into double helix exrusion bulking machine, in 7 × 105At Pa and 125-140 DEG C, by the pore pressure of a diameter of 0.1-0.8mm
Go out, carry out pre-gelatinized, drying, after pulverizing pre-gelatinized separating protein powder of peanut；
（2）Chestnut shell is dried and puts in 340-405 DEG C of charing process 30-40 minute in retort, take out and be cooled to 80-90 DEG C
Add vinyltrimethoxy silane ultrasonic grinding 10-15 minute, dry and be placed again into processing in 570-620 DEG C in retort
20-30 minute, cooling adds 1-hydroxy ethylidene-1,1-diphosphonic acid, Rhizoma et radix valerianae oil grinding 20-30 minute, obtains modified chestnut shell powdered carbon；
（3）The water of residual mass is placed in reactor, adds benzyl alcohol, N-Methyl pyrrolidone stirring and evenly mixing, while stirring
Add dehydrated alcohol, ethyl cellulose 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 is main solvent after being combined benzyl alcohol, N-Methyl pyrrolidone, the phase with paint film
Dissolubility is good, leads to macromole volume to increase, produces internal stress, so that the adhesive force reduction of paint film and ground is departed from；With anhydrous second
Alcohol is cosolvent, can accordingly reduce the consumption of main solvent, reduces cost；Bondd using pre-gelatinized separating protein powder of peanut as thickening
Agent, is firmly bonded with coating surface that wall built-up is good and rapid-drying properties are good, can depart from rapidly metal surface, reduces to the corruption to metal
Erosion；Adding particulate modified molybdenum chestnut shell powdered carbon is that filling adsorption is strong, on the one hand extends and coating surface swellability time of contact
Good, on the other hand swelling rear depainting solution can be adsorbed and come off together in hole, improve the removal efficiency of paint film, and depainting produces
Raw waste residue is biodegradable, environmental protection efficiency high；It is also added with the compound paint stripper that Rhizoma et radix valerianae oil and other effective ingredient are obtained simultaneously
Deodorizing effect is significantly safe, and paint removing effect is substantially better than traditional paint stripper.
