Abstract
The present invention provides a high-efficiency paint remover. Said paint remover is composed of dichloromethane, dioxane, alcohol, phenol, surfactant, formic acid, paraffin and cellulose, and can be used for removing old paint layers of alkyd resin coating, nitrolacquer, epoxy resin paint and amino-resin coating, etc. It features high paint-removing efficiency and speed and no corrosion to metal surface.
Description
Automobile, steamer, passenger car railway carriage or compartment, aircraft and some machinery equipment etc. need remove the paint coating of outside surface when carrying out large repairs, and carry out application again.With manually removing, not only waste time and energy, and damage the metallic surface easily, generally use paint remover that paint coating is removed.The paint remover of Xiao Shouing in the market, ubiquity is suitable for shortcomings such as enamelled coating is single, and depainting efficient is low, and volatility is bigger, and trickling speed is very fast.
The efficient old paint coating that the present invention relates to removes agent, be with methylene dichloride for mainly removing solvent, add an amount of compositions such as alcohol, dioxan, phenol, tensio-active agent, organic acid, paraffin and Mierocrystalline cellulose.
The efficient paint remover that the present invention relates to is applicable to removing of used paint layers such as alkyd paint, pyroxylin(e)finish, acrylic paint, epoxy-based lacquers, amino lacquer, phenolic resin coating and polyurethane paint.Have depainting efficient height, paint stripping rate is fast, and the evaporation rate of paint remover waits characteristics more slowly.The preparation of paint remover:
A: methylene dichloride 36g
Methylcellulose gum 1g
Ethanol 5g
1,4-dioxane 5g
Methylcellulose gum is added in the methylene dichloride, stirs, add ethanol and dioxane then, stirring and dissolving is even.
B: methylene dichloride 40g
Phenol 5g
Polyoxyethylene octylphenol ether 2g
Paraffin 1g
Phenol, polyoxyethylene octylphenol ether and paraffin etc. are joined in the methylene dichloride, and stirring and dissolving is even.If dissolve slowlyer, can heat slightly, it is fully dissolved.
C: A and B are mixed, add 5g formic acid then and stir.Stripping test:
Get the alkyd paint metal testing plate, 150g/m with on sealing with wax, is pressed then in four limits
2Amount paint remover is coated with last layer on the test piece surface equably.After several seconds, the paint film swelling leaves the metallic surface.After the enamelled coating of taking off wiped, clean with distilled water, paint coating extrusion rate 100% is observed the metallic surface and is not had any corrosion phenomenon.
