Abstract
The invention relates to a neutral paint stripper which can be widely used in the paint strippers of various primer films. The neutral paint stripper mainly comprises dichloromethane, methanol, ethanolamine, 2-ethoxyethanol, carboxymethyl cellulose, sodium alkyl benzene sulfonate, paraffin wax and water.
Description
Technical field
The invention belongs to function fine chemicals field, be meant a kind of neutral paint remover especially.
Background technology
Coating is widely used in protection and decorative article surface, but in use, and the paint film of coating can sustain damage, wear out or owing to aesthetic reasons is safeguarded or upgraded.When safeguarding or upgrade, common way is that original coating is removed, again spraying again.
The coating paint film is mainly by film forming matter, pigment, and filler and suitable adjuvants are formed, and the depainting principle of paint remover is exactly to utilize the structure composition that solvent destroys paint film to the dissolving or the swelling action of film forming matter or the bonding force of paint film and base material.
In the prior art, remove paint film and all adopted paint remover to handle, physics mode is handled and has seldom been used.And existing paint remover can be divided into two types, and basic paint remover and acid paint remover, this paint remover of two types mainly are to utilize the acidity in the paint remover to come to remove fast paint film with alkalescence.Though these two types of paint removers are in use convenient, and certain defective is arranged, the shortcoming of these two types of paint removers mainly is:
No matter one is acid paint remover or basic paint remover, in depainting, all can certain corrodibility be arranged to base material, this character can have influence on the quality of product, also can cause the waste of resource.
Two, this type paint remover has certain pollution to environment, is using the same environmental protection requirement now of this type paint remover not to be inconsistent.
Therefore, develop a kind of environmentally friendly simultaneously to the low corrosion of product base material or not have the corrosive paint remover be those skilled in the art's striving direction.
Summary of the invention
The objective of the invention is to develop a kind of little to environmental influence, produce simple, non-corrosive neutral paint remover.The present invention anatomizes and selects through the component of being selected for use is passed through, and through the shared proportion of each component is analyzed, develops the patent art scheme.
The present invention realizes through following technical scheme:
A kind of neutral paint remover, each component is counted by weight percentage and is comprised:
As further improvement, neutral paint remover of the present invention, each component is counted by weight percentage and is comprised:
Sodium alkyl benzene sulfonate described in the present invention is meant X 2073.
The invention has the beneficial effects as follows:
1, the pH value of the paint remover that the present invention processes is to be neutrality between the 6.7-8.4, and the base material corrodibility of treating depainting is very little.
2, the present invention has overcome the restriction of former paint remover, and its depainting time is compared with existing paint remover, be higher than basic paint remover.
3, compare with existing paint remover, with the usage quantity decline 5%-10% under the homalographic, reduced the pollution treatment capacity.
Embodiment
Describe embodiments of the invention below in detail, it is exemplary that described embodiment all belongs to, and only is used for can not being interpreted as limitation of the present invention to realizing explanation of the present invention.In description of the invention, can't limit example all be provided in the requirement protection domain with the present invention, be representative and limited several points only can be provided.
Working method of the present invention is, with the demand-driven weight of each component, puts into the closed reactor of belt stirrer respectively, stir under the normal temperature, 30-50 minute, then with the storage of finished products that stirs in sealed vessel.
When adopting paint remover of the present invention to carry out depainting, the temperature that is adopted can be in 5 ℃ of-35 ℃ of scopes, preferably in 15 ℃ of-30 ℃ of scopes.In preferable range the depainting time shorter, be because when preferable range, treat that the superpolymer in the depainting film is in inert condition, mobility is low, the space is stable, it is very fast that the paint remover molecule infiltrates paint film bottom depainting easily.Temperature is too high when depainting, and the paint remover evaporation rate is too fast, when paint remover also infiltrates paint film, possibly just not volatilize, and influences the speed of depainting on the contrary.
Embodiment one
Select methylene dichloride for use, 5% methyl alcohol, 8% thanomin, 8% ethylene glycol ethyl ether by weight 63%; 6% methylcellulose gum, 5% X 2073,2% paraffin, all the other are water; Each component amounts to double centner, above-mentioned each component is successively added in the closed reactor that has whisking appliance, adds the not influence of time ordered pair product performance performance; In the present embodiment, the churning time of selection is 40 minutes, also can select in other embodiments of the invention to stir 30 minutes, 35 minutes, 45 minutes, 50 minutes; The time of stirring can be different according to the difference of outside temperature, generally can realize effect of the present invention fully at 40 minutes, but when extraneous temperature is high; Can suitably reduce churning time, such as 30 minutes or 35 minutes, or even less time also can realize the present invention.When the temperature in the external world is hanged down, should suitably select for use churning time longer, such as 45 minutes, 50 minutes or longer time.It is for use in the sealed vessel then the product of processing to be packed into.
Embodiment two
In various embodiments of the present invention, reaction times and the reaction kettle of selecting for use or storage vessel are all same or similar, just no longer repeat explanation among the embodiment afterwards.Different only is the weight ratio of each component, and in the present embodiment, the weight ratio of paint remover each component does; 69% methylene dichloride, 5% methyl alcohol, 8% thanomin; 8% ethylene glycol ethyl ether, 3% methylcellulose gum, 2% X 2073; 2% paraffin, all the other are water, each component amounts to double centner.Other implementation condition is identical with embodiment one.
Embodiment three
In the present embodiment, select 65% methylene dichloride for use, 10% methyl alcohol, 5% thanomin; 5% ethylene glycol ethyl ether, 6% methylcellulose gum, 5% X 2073,2% paraffin; All the other are water, and each component amounts to double centner, and other implementation condition is identical with embodiment one.
Embodiment four
In the present embodiment, select 65% methylene dichloride for use, 7% methyl alcohol, 5% thanomin; 5% ethylene glycol ethyl ether, 6% methylcellulose gum, 5% X 2073,5% paraffin; All the other are water, and each component amounts to double centner, and other implementation condition is identical with embodiment one.
Embodiment five
In the present embodiment, select 69% methylene dichloride for use, 7% methyl alcohol, 5% thanomin; 5% ethylene glycol ethyl ether, 4% methylcellulose gum, 4% X 2073,3% paraffin; All the other are water, and each component amounts to double centner, and other implementation condition is identical with embodiment one.
In the present invention, embodiment five in the preferred embodiment, but the embodiment that the present invention selected for use only is in order to prove practicality of the present invention, is not above embodiment only to be arranged in protection scope of the present invention in order to proof the present invention.The prescription of other ratio of the present invention also can well be accomplished the depainting task, and only because can't each embodiment enumerated out one by one, if desired, the contriver can be provided in the various embodiment in the requirement resist technology condition and range of the present invention.
The above only is a preferred implementation of the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the application's principle; Can also make some improvement and retouching, improve and retouch the protection domain that also should be regarded as the application like this.
