Abstract

The invention relates to the field of chemical industry paint, in particular to an environment-friendly aqueous paint remover. The paint remover is prepared by mixing and compounding the following components in parts by weight: 25-45 parts of dichloromethane, 7-8 parts of vinyl alcohol, 6-7 parts of propanol, 3-9 parts of methyl cellulose, 7-11 parts of diethyl carbonate, 3-4 parts of a surfactant, 20-24 parts of liquid paraffine, 5-6.5 parts of a thickening agent, 12-14 parts of phosphoric acid, 1-2 parts of sodium nitrite and 12-14 parts of a solvent. The environment-friendly aqueous paint remover disclosed by the invention is high in depainting speed and is unlikely to volatilize; the aqueous paint remover can be directly applied to a painting surface under a normal atmospheric temperature for depainting, and the paraffine for volatilization resistance is contained in the components, so that the paint remover is favorable for renewedly painting workpieces of which the paint films are removed; the paint surfaces of automobiles, electric appliances, furniture and the like can be effectively removed, and the surfaces of metal and wood are not damaged. The paint remover is simple in manufacturing working procedures, is convenient to operate, is low in cost of raw materials, and has no residues, so that the paint remover is suitable for factory type large-scale production.

Description

A kind of environment-friendly type aqueous paint remover
Technical field
The present invention relates to a kind of environment-friendly type aqueous paint remover, belong to paint remover technical field.
Background technology
Along with expanding economy, the protection against corrosion brushing of people in fields such as traffic, industry, building, house decoration and finishing refresh, and require the old paint of removing more and more, heavily refresh the operating technique of paint.Depainting technical products in the market, although old paint can be decorporated, paint removing effect is not good, and along with irritating chemical odor, low toxicity and also can corrode low material, lower ground working life, have a strong impact on problems such as recoating packing quality.
Summary of the invention
The present invention proposes a kind of environment-friendly type aqueous paint remover, solve problems of the prior art.This paint remover depainting performance is good, paint stripping rate soon, not volatile; The lacquer paintings such as automobile, electrical equipment, furniture be can effectively remove, metal and wood surface do not damaged.
For solving the problems of the technologies described above, the technical solution used in the present invention is achieved in that
A kind of environment-friendly type aqueous paint remover, is made up of the component of following parts by weight:
Methylene dichloride 25-45 part, vinyl alcohol 7-8 part, propyl alcohol 6-7 part, methylcellulose gum 3-9 part, diethyl carbonate 7-11 part, tensio-active agent 3-4 part, whiteruss 20-24 part, thickening material 5-6.5 part, phosphatase 11 2-14 part, Sodium Nitrite 1-2 part and solvent 12-14 part.
As preferred technical scheme, this environment-friendly type aqueous paint remover is made up of the component of following parts by weight:
Methylene dichloride 30 parts, vinyl alcohol 7.5 parts, propyl alcohol 6.5 parts, methylcellulose gum 6 parts, diethyl carbonate 9 parts, 3.5 parts, tensio-active agent, whiteruss 22 parts, thickening material 6 parts, phosphatase 11 3 parts, Sodium Nitrite 1.5 parts and solvent 13 parts.
Solvent in described paint remover composition is water.
The invention has the beneficial effects as follows:
Environment-friendly type aqueous paint remover of the present invention, paint stripping rate soon, not volatile; At normal temperatures, directly can be painted on lacquer painting and carry out depainting, the paraffin containing volatilization prevention in component, is conducive to the application again removing paint film workpiece; The lacquer paintings such as automobile, electrical equipment, furniture be can effectively remove, metal and wood surface do not damaged.Paint remover production process is simple, easy to operate and the prices of raw and semifnished materials are cheap, does not stay residue, is applicable to factory's formula scale production.
