Abstract
The invention discloses a kind of methods of Oil Paint Slag regeneration, the method is that the influence for eliminating water in paint vehicle is combined with physical method and chemical method, and utilize the method raising regeneration paint amount for adding pigment powder and the ratio for painting the quantity of slag, it is characterised in that the component and content of deicer are as follows in chemical method used: (parts by weight) alcohols solvent 5-18;Hydrocarbon solvent 10-70;Ketones solvent 2-10;Silicone oil 0.5-5.The present invention eliminates remaining moisture content using chemical deicer, to eliminate influence of the water content to coating.And promoting paint film smooth, effect is very significant.
Description
Technical field
The present invention relates to a kind of methods of Oil Paint Slag regeneration.
Background technique
Still significant fraction uses spraying operation at present for China's paint industry and coating process.Especially decorative face
Paint coating.And in spraying operation the utilization rate of material of paint has the material of paint of nearly half or so to damage in 40-70% or so
It loses, the overwhelming majority lands overboard contaminated and becomes waste painting slag in the material of paint of loss.
Fresh waste paint slag (the paint slag generated in 2 days) will make it by restoring after re-working close to original paint property
The qualified paint that can be recycled of energy it may first have to remove the moisture content (or buck) in paint slag, secondly also to supplement suitable
Pigment part and base-material component.This technology, which is characterized in that exploring first, combines elimination water with physical method and chemical method
Influence in paint vehicle, and using the method for pigment powder is added come regeneration waste paint slag, thus make to regenerate paint amount and paints the quantity of slag
Ratio is reduced significantly, and is conducive to largely utilize waste paint slag.
Summary of the invention
The first situation is to paint the overboard and waste paint slag without highly basic pollution of slag, is carried out using physics dewatering first
Being squeezed, being pressed to the moisture content of paint block entrained with, got rid of, dried manually or mechanically, removes 90% or more moisture content, then will paint
Clinker releases filtering after putting into agitator tank stirring, dissolution, filtered paint slag is stood 10 hours, remaining moisture content suitable one
Part can float on top layer (obvious water layer) by the big paint slag extrusion of pigment part content, can manually wipe off.Extruding in program
It gets rid of and is performed such, i.e., the paint clinker for being 3kg or so the paint slag cutting fished out first is squeezed, then be placed in automatic spin-drying
Machine is dehydrated 3-4 minutes, and taking-up, which is dried, can put into stirring solvent.
Second situation is that paint slag is overboard, and added with lacquer mist coagulant in water, main ingredient is strong basicity medicine in flocculating agent
Product, it can make organic polymer resin (base-material in paint) structure go to pot, and lose the function of inclusion pigment, make in paint vehicle
Pigment and binder ratio lack of proper care.Recycling to this paint slag is, the freshness of holding paint slag primary using recycling in 18 hours, and
The paint slag of recycling is soaked in sink, bases is precipitated, then is rinsed with suitable tap water, until the pH value of paint block is 7 left
The right side, processing later can be handled by the first situation.
Overboard paint slag recycling is after the dehydration of the first one-step physical, still with the presence of a small amount of moisture content (about below 5%), this part
If not handling, the paint film after making japanning generates various disadvantages, such as blistering, floating, volcanic crater, shrinkage cavity, depression points, pin hole
Deng will seriously affect the performance of paint film.Therefore the present invention eliminates remaining moisture content using chemical deicer, to eliminate water content
Influence of the paint vehicle to coating within 8%.
Chemistry deicer according to the present invention is made of following Main Components: 5-18 parts of alcohols solvent, hydrocarbon solvent
10-70 parts, 2-10 parts of ketones solvent, 0.5-5 parts of silicone oil.The deicer of 1-30% is added in recycling paint vehicle, can not only disappear
Except the various disadvantages of above-mentioned paint film, and promote paint film smooth, effect is very significant.
Ketones solvent is n-amyl alcohol, n-butanol, ethyl alcohol in deicer of the present invention, be can be used alone, and can also be mixed
It closes and uses.
Hydrocarbon solvent is toluene, dimethylbenzene, ethylbenzene in deicer of the present invention, be can be used alone, and can also be mixed
It uses.
Ketones solvent is acetylacetone,2,4-pentanedione, acetone, cyclohexanone in deicer of the present invention, be can be used alone, can also be with
It is used in mixed way
Silicone oil is ethyl silicon oil, methyl phenyl silicone oil, organosiloxane in deicer of the present invention, be can be used alone,
It can be used in mixed way.
The present invention using plus pigment powder come adjust regeneration paint pigment and base-material it is out of proportion, specific practice be recycling
After painting slag, after dehydration → dissolution → filtering → grinding reaches fineness requirement, directly plus pigment powder is into raw lacquer again, added
The amount of pigment entered is seldom, changes less to whole volume amount, so the finished product being made into raw lacquer again: the paint quantity of slag=2.5~2.8: 1.
Specific implementation method
Certain domestic large-scale producer product has agricultural vehicle, tractor, low-speed cars etc., the mainly middle blue polyester of the finishing coat of coating
There are 10 painting lines in amido finishing coat, full factory, there is the middle blue polyester of 45% recoverable in the 3.8T paint slag generated daily
Finishing coat paint slag.It is overboard to paint slag, but is not polluted by buck.
Physics dehydration is carried out by the first situation of the invention when carrying out regeneration, that is, carries out pair manually or mechanically
The moisture content of paint block entrained with is squeezed, is dried, is dried, and 90% or more moisture content is removed, and paint clinker is then put into agitator tank
Stirring, dissolution release filtering, by filtered paint slag standing 18 hours, remaining moisture content quite a few can be contained by pigment part
It measures big paint slag extrusion and floats on top layer (obvious water layer), manually struck off.Extruding in program, drying, i.e., being fished out
The paint clinker that slag cutting is 2.5kg or so is painted, is first squeezed, then is placed in automatic spin-drying machine and is dehydrated 1-4 minutes, taking-up is dried
Stirring solvent can be put into.
Chemical method eliminates the influence of moisture content, and chemical deicer is added by following Main Components:
Ethyl alcohol/n-butanol (7: 1) 16
Diformazan benzene/methylbenzene (1: 1) 71
Acetone 8
Ethyl silicon oil 5
27% deicer is added in recycling paint vehicle, treated paints raw material of the slag as regeneration.Aligning raw lacquer again
When pigment, added pigment is that 3.5 kg of phthalocyanine blue powder, titanium dioxide 9.5kg, mixing is added in blue paint slag lysate in every 100kg
It stirs evenly, is ground to fineness and reaches 40 μm, finally align gloss with 25kg amido polyester resin, reach close to original paint
Appearance (top grade regeneration paint is horizontal), recycled product paint amount: the paint quantity of slag=2.4: 1, if being made into low-grade grey priming paint (matt
Paint), then finished product regenerates paint amount: the paint quantity of slag=2: 1.Quality inspection is painted through regeneration, related test stone is fully achieved, it can
To re-use.
Embodiment 2
Certain domestic producer uses solvent type black chlorinated rubber chassis paint hand spray, and the paint quantity of slag picked up daily has 0.5T.
Because alkalinity is strong added with lacquer mist coagulant in water, thus when the paint slag regeneration processing of recycling by above-mentioned second situation into
Row processing.It takes recycling in 18 hours primary for 100kg paint slag, keeps the freshness of paint slag, and the paint slag of recycling is soaked in
In 2500kg sink, bases is precipitated, then is eluted to the PH=7 or so of paint block, processing later with suitable tap water
By the paint Slag treatment of the first situation.Other processing steps of reclaiming are similar to Example 1.
