Abstract
The invention discloses a water-base paint remover as well as a preparation method and application of the water-base paint remover. The water-base paint remover comprises the following ingredients in parts by weight: 40 to 60 parts of N-methyl pyrrolidone, 40 to 60 parts of ethylene glycol monobutyl ether and 0.2 to 0.5 parts of moistening agents. The water-base paint remover can be used through being directly brushed and coated on finish of indoor waterborne wall finish to be removed, and can also be used through being mixed with water in a proportion being 1:(1-3) (the weight ratio) according to the aimed wall finish under a practical condition, so that the goal of cost saving is reached. Anti-volatilization paraffin ingredients are not used, so that the cleaning is easy after paint removal, in addition, a putty layer cannot be damaged after the pain removal, the trouble of secondary putty scraping and coating is avoided, and secondary coating and installation can be carried out after simple treatment on wall surface.
Description
Technical field
The present invention relates to the depainting paint field, relate in particular to water-base depainting agent of a kind of energy fast eliminating wall paint and its preparation method and application.
Background technology
House decoration when paint film flavescence, dirty, the situation such as come off and finishing general layout occurring and need to change, just need to be renovated metope after the application wall paint several years.Need to remove wall paint during renovation.For this situation, people root out with scoop usually, and this operating method not only working efficiency is low, and easily cause metope rugged, destroy the planeness of metope, when particularly running into the elastic emulsion paint on the market, just can't root out fully at all.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of water-base depainting agent and its preparation method and application, described water-base depainting agent energy fast eliminating wall paint, in the time of need to renovating mainly for the indoor wall finish paint metope is processed, can make things convenient for, effectively remove the finish paint of wall paint and not injure putty layer, make things convenient for the secondary application, be intended to solve the existing wall paint technology that removes and have inefficiency, destroy metope and can't root out the problem of wall paint fully easily.
Technical scheme of the present invention is as follows:
A kind of water-base depainting agent, wherein, described water-base depainting agent is counted by weight, comprises following component:

Butyl glycol ether 40 ~ 60;
Wetting agent 0.2 ~ 0.5.
Described water-base depainting agent, wherein, described wetting agent is polyether siloxane copolymer.
A kind of preparation method of aforesaid water-base depainting agent wherein, may further comprise the steps:
Add by weight successively N-Methyl pyrrolidone, butyl glycol ether and wetting agent, with 80-100 rev/min of stirring;
Mix packing.
A kind of application of aforesaid water-base depainting agent wherein, is used for removing of metope enamelled coating with described water-base depainting agent.
The application of described water-base depainting agent wherein, is used for removing of metope enamelled coating with described water-base depainting agent, specifically may further comprise the steps:
Described water-base depainting agent brush is being needed on the metope of depainting;
When waiting to be brushed with the metope surface drying of described water-base depainting agent, the lower metope enamelled coating of shovel.
The application of described water-base depainting agent, wherein, described water-base depainting agent and water are used further to removing of metope enamelled coating after blending in the ratio of 1:1～3 times.
Beneficial effect: water-base depainting agent of the present invention can use by the finish paint of direct brushing at the required indoor waterborne wall surface lacquer that removes, also can according under the practical situation required for wall paint, mix rear the use with water in the ratio (by weight) of 1:1～3, to reach the purpose of saving cost.The present invention is easy to cleaning, and does not injure putty layer behind the depainting owing to do not use the paraffin composition of volatilization prevention behind the depainting, the trouble of removing secondary blade coating putty from can the secondary application after metope simply put in order.
Embodiment
The invention provides a kind of water-base depainting agent and its preparation method and application, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Water-base depainting agent provided by the present invention is take organic solvent as main component, by adding other compositions (wetting agent) so that the wetting of paint film and infiltration are produced synergistic a kind of transparent liquid.Water-base depainting agent of the present invention can use by the finish paint of direct brushing at the required indoor waterborne wall surface lacquer that removes.Also can according under the practical situation required for wall paint, and use after water mixes in the ratio (by weight) of 1:1～3.Like this, can regulate for the wall paint of different class the strong and weak ability of depainting of paint remover, to reach the purpose of saving cost.The present invention is easy to cleaning, and does not injure putty layer behind the depainting owing to do not use the paraffin composition of volatilization prevention behind the depainting, the trouble of then removing secondary blade coating putty from can the secondary application after metope simply put in order.Product of the present invention has and does not contain corrosive acid-basicity chemical ingredients, and has the flash-point height, transportation and storage safe advantages of higher.
Particularly, described water-base depainting agent is counted by weight, comprises following component:
| Sequence number | Title | Deal |
| 1 | N-Methyl pyrrolidone | 50±10 |
| 2 | Butyl glycol ether | 50±10 |
| 3 | Wetting agent | 0.2-0.5 |
Wherein, described wetting agent is polyether siloxane copolymer.
The preparation method of described water-base depainting agent also is provided among the present invention, may further comprise the steps:
The first step: add by weight successively N-Methyl pyrrolidone, butyl glycol ether and wetting agent, with 80-100 rev/min of stirring;
Second step: stir and to pack after mixing in about 10 minutes.
The application of described water-base depainting agent also is provided among the present invention, described water-base depainting agent is used for removing of metope enamelled coating, its depainting process may further comprise the steps:
S1: described water-base depainting agent is being needed on the metope of depainting with the row brush brush;
S2: wait for after about one hour that when waiting to be brushed with the basic surface drying of metope of described water-base depainting agent, namely available scoop becomes metope enamelled coating under the slice bar easily.
If there is can rooting out easily, but finish paint do not fall down in flakes when rooting out under S2, when forming pasty state or putty layer and sustaining damage, roots out after can waiting for a period of time again again.If there is in the difficult situation about rooting out, can brush again described water-base depainting agent one time when under S2, rooting out, can solve.
Need to prove for described depainting applying step: this application step can be used as a reference general depainting.Excellently have poorly because the wall paint performance has on the market, when removing the lower wall paint of class, can blend afterwards by described S1 the S2 step application in the ratio of 1:1～3 times to water-base depainting agent of the present invention and water.In actual application, if the wall paint that will remove is had little understanding, can carry out small area and remove test, to determine suitable depainting step.The paint remover that can avoid like this using is crossed and is added by force and less the very low water of cost, or a little less than adding water excess and making paint removing effect excessively, to reach saving of labor, laborsaving, saves the effect of cost.
The present invention is described in more detail below in conjunction with embodiment.
Embodiment one:
