Abstract
The invention discloses a method for cleaning a coating film, and the cleaning agent comprises 45-55% of diglycolamine, 20-30% of Isoprene enolate, 5-10% of trifluorovinyl ether, 0.1-0.5% of mercaptan, 6-13% of hexamethyldisiloxane, 2-8% of hexaalkyl phenoxyl poly(ethoxy butanol), and 2-5% of powdery sodium hydroxide, wherein the sum of the percents of the components is 100%; the cleaning method is performed under ultrasonic vibration, and is convenient and rapid for the removal of a film on a substrate.
Description
Technical field
The present invention relates to the method that a kind of cleaning dope is filmed.
Background technology
Existing general third vinyl solution that adopts of unsaturated resin coating that cleans goes to clean, and price is high, is unfavorable to the purged and packed container.Other expensive chemical reagent solution of employing is also arranged, generally apply receiving the high restriction of cost, and have the chemical reagent that much can clean unsaturated resin coating also to have contaminate environment, should not generally promote the use of.
Remover in the prior art can remove oil-based paint, pyroxylin(e)finish, alkyd paint etc.Removers such as T1 commonly used both at home and abroad, T2 are to form with organism such as toluene, acetone, YLENE, ethanol, paraffin.These removers are to removing polyester, and epoxy or polyester epoxy electrostatic spraying powder coating are very difficult.
Because these polyester, epoxy or polyester epoxy powder coating are to adopt electrostatic spraying, and are 100% solid matter, coating is evenly durable, and is firm, strong adhesion, excellent spring.Therefore the removal of solidified powder coating is quite difficult.The domestic existing method that this type coating mainly is the husky mill of employing that is used for removing.The method of burning is adopted in the work at position, dead angle usually.Effect is not ideal enough, and is prone to cause distortion, the damage of workpiece, and adopts the remover that contains formic acid, and is then perishable.Therefore, when the work of these powder coatings of spraying, once sustain damage or remove because of off quality, carrying out application again, is difficulty very.
Summary of the invention
To the deficiency of prior art, it is a kind of cheap that one of the object of the invention is to provide, environmentally safe, be suitable for the clean-out system of removing coating that large-scale popularization is used.
According to aforementioned purpose and other content, composition of the present invention is following:
The compsn that a kind of cleaning dope is filmed, form by the component of following weight per-cent:
Diglycolamine 45-55%
Prenol 20-30%
Fluoromar (Ohio Med.) 5-10%
Mercaptan 0.1-0.5%
SWS-F 221 6-13%
Six alkyl phenoxy polyethoxye butanols 2-8%
Powdered sodium hydroxide 2-5%,
Each component sum is 100%.
Described compsn, it cleans optimum temperature range is 45-55 ℃.
Concrete cleaning step is:
1) with the removal foreign material of filming on the base material, soil dust is put in the clean-out system after washing;
2) clean-out system is heated to 45-55 ℃, under ultrasonic agitation, cleans;
3) wait to film and come off fully, take out base material, clean bright dipping or the polishing back is used as blank base material.
Said the filming of filming for urethane, epoxy resin, vinyl resin any one or its multipolymer, homopolymer.
Said coating capable of washing is water-borne coatings, solvent based coating or powder coating.
The activity of Fluoromar (Ohio Med.) and the activity of fluorine atom, and the alkalescence of sodium hydroxide and the activity of sodium ion make with diglycolamine and prenol to be that the cleansing power of the scavenging solution of primary solvent clean-out system is greatly improved; Simultaneously; UW is auxiliary to be cleaned, and can use cavitation effect of ultrasonic waves, and the one of which accelerated reaction is carried out; It two can play physics to filming and peel off effect, effectively improves cleaning speed.
