Abstract

The invention relates to a powerful paint stripper comprising the following components by weight percent: 0-5 percent of surface active agent, 72-78 percent of dichloromethane, 0-3 percent of ethylacetate, 0.78-0.8 percent of thickener, 0.6-0.7 percent of ceresin wax, 4.85-10 percent of phenol, 5-9 percent of alcohol, 0-6 percent of methanoic acid, 0-6 percent of ammonia water and 0-1 percent of sodium nitrite. The invention can effectively remove paint on the metal surface of planes and on the train wheel surface so as to perform flaw detection and repaint on the metal materials without damaging metal and wood surfaces, and has excellent depainting performance, low use amount and low depainting cost.

Description

A kind of powerful paint stripper

Technical field

The present invention is a kind of paint remover that can remove aircraft metallic surface paint and train wheel surface paint effectively.

Background technology

Present domestic airline carriers of passengers and military aircraft have more than 3000, and annual speed increase with more than 50, and general 3-4 will keep in repair once; Average 60 liters of every sortie consumption; The aircraft annual consumption is if need 60000 liters, and about 50 yuan of every liter of prices only are used for the aircraft depainting whole year and add up to 3,000,000 yuan.Add the aircraft of other China General Aviation Corp, national consumption is more than 4,000,000 yuan.And at present, domestic train maintenance industry consumption is bigger, and annual consumption is greatly about more than 30,000,000 yuan; Other civilian industries (flight-line maintenance industry) consumption is maximum, and annual consumption is greatly about more than 5,000 ten thousand yuan, though also there is production in domestic some producer; But effect does not all reach requirement, like the big holder shop military airfield aircraft maintenance factory in Hunan, oneself converts paraffin wax with methylene dichloride exactly and is dealing with; Though certain effect is arranged; But take off untotally, lean on the artificial labour intensity of removing old paint film very big, make the cost of depainting increase many virtually.

Summary of the invention

The object of the invention aims to provide and a kind ofly can remove aircraft metallic surface paint and train wheel surface paint effectively, is convenient to metallic substance is detected a flaw and painted again, does not damage metal and wood surface, has the paint remover of good depainting performance.

The objective of the invention is to realize through following manner: following all by weight.

A kind of powerful paint stripper comprises following each weight part raw material: tensio-active agent 0-5%, methylene dichloride 72-78%, ETHYLE ACETATE 0-3%, thickening material 0.7-1%; Paraffin 0.6-0.7%, phenol 4-10%, ethanol 5-9%; Formic acid 0-6%, ammoniacal liquor 0-6%, Sodium Nitrite 0-1%.

Described tensio-active agent is preferably X 2073 and ethylene glycol monobutyl ether.

X 2073 preferably accounts for the 55-65% (most preferably being 60%) of tensio-active agent weight part in the tensio-active agent; Ethylene glycol monobutyl ether preferably accounts for the 35-45% (most preferably being 40%) of tensio-active agent weight part.

Adding the preferred weight range of ETHYLE ACETATE is 2.5-3%.

When adding ammoniacal liquor, Sodium Nitrite, preferred weight range is ammoniacal liquor 5-6%, Sodium Nitrite 0.9-1%.

The preferred weight proportion of the present invention is: methylene dichloride 72-78%, ETHYLE ACETATE 0-3%, thickening material 0.7-1%, paraffin 0.6-0.7%, phenol 4-10%, ethanol 5-9%, formic acid 0-6%, ammoniacal liquor 5-6%, Sodium Nitrite 0.9-1%.

Select thickening material preferable methyl Mierocrystalline cellulose.

Product of the present invention, constant product quality, be convenient to metallic substance detect a flaw with again paint, do not damage metal and wood surface, have good depainting performance, and consumption is few, the depainting cost is low.It is the good paint remover of a kind of paint removing effect.

Good performance below the tool of the present invention:

1. performance is superior to traditional paint remover.It can remove the old paint film in metallic surface safely and up hill and dale, and does not damage primer, also do not corrode aluminium or cause hydrogen embrittlement.

2. can penetrate old paint film, old paint film is heaved, only need the water wiping, just can remove old paint film, time saving and energy saving.

3. the scope of application is very wide, international and domestic various military, civilian aircrafts, and type is general, and railway and other industrial maintenances can be general;

4. do not burn, flash-point is high, and accumulating is all as safe as a house with use, through detecting flash-point: 55 ℃, proportion: 1.19.

5. oxious component such as heavy metal is lower than national standard.

The present invention succeeds in developing, and has just in time satisfied the requirement of import substitutes, satisfies the needs that domestic various airline carriers of passengers, civilian aircraft, military aircraft outside surface remove old paint film.The needs that railway and other maintenance industries remove old paint film have also been satisfied.
