Problems solved by technology

[0003] 1. Serious pollution and great harm to human body, this is because organic solvents of benzene substances are more toxic to human body;
[0004] 2. It also has a dissolution effect on plastics. It is not suitable to remove paint from plastic as the base material. It is also necessary to recycle the plastic base. However, some water-based paint removers are slow or even unable to remove the paint;
[0005] 3. High cost of paint removal

Embodiment 1

[0034] A kind of environment-friendly water-based paint remover for removing plastic surface paint according to the present invention comprises the following raw material components in proportions by weight:

[0035] 13 parts of low molecular weight alcohol;

[0036] 13 parts of sodium hydroxide;

[0037] 3 parts of fatty alcohol polyoxyalkyl ether;

[0038] 3 parts of silicate compound;

[0039] 68 parts water.

[0040] Low molecular weight alcohol is a mixture of methanol, ethanol, propanol and isopropanol.

[0041] Silicate compounds are mixtures of sodium silicate, potassium silicate, water glass and aluminum silicate.

[0042] Fatty alcohol polyoxyalkyl ethers have good penetration, emulsification and cleaning properties.

[0043] Silicate compounds act as bulking agents in paint strippers.

[0044] The principle of paint removal is: the paint does not rely on solvents to dissolve, but small molecules penetrate into the paint to generate bubbles, and form a mechanic...

Embodiment 2

[0049] An environmentally friendly water-based paint remover for removing paint on plastic surfaces, comprising the following raw material components in proportions by weight:

[0050] 13 parts of low molecular weight alcohol;

[0051] 15 parts of sodium hydroxide;

[0052] 5 parts of fatty alcohol polyoxyalkyl ethers;

[0053] 5 parts of silicate compound;

[0054] 62 parts water.

[0055] The low molecular weight alcohol is a mixture of n-butanol, tert-butanol, pentanol, hexanol and cyclohexanol.

[0056] The silicate compound is a mixture of tricalcium silicate, dicalcium silicate, calcium silicate and sodium metasilicate.

[0057] The preparation method of the above-mentioned environment-friendly water-based paint remover, first configure sodium hydroxide and water to form a sodium hydroxide solution, then add low-molecular alcohol, fatty alcohol polyoxyalkyl ether and silicate compound, and stir to completely dissolve all components , to obtain the paint remover.

Abstract

The invention provides an environment-friendly water-based paint remover for removing paint on the surface of plastics as well as a preparation method and an application method of the paint remover. The environment-friendly water-based paint remover comprises, in parts by weight, 10-30 parts of low molecular alcohol, 10-30 parts of sodium hydroxide, 1-10 parts of fatty alcohol polyoxyalkyl ether, 1-15 parts of silicate compound and 40-70 parts of water. The environment-friendly water-based paint remover is capable of removing vacuum plating primer coating, surface gloss oil, acrylic air-dry paint, double-compound polyurethane paint and nitrolacquer on base materials such as ABS (Acrylonitrile Butadiene Styrene), HIPS (High Impact Polystyrene), nylon and BMC (Bulk Molding Compound), has no harm to the plastic base materials, and is environmental friendly; waste plastic parts can be utilized after being depainted and recoated, and good economic benefit and social benefit can be achieved; the environment-friendly water-based paint remover is efficient and practical, and is long in service cycle without harm to the health of the operating personnel.

Description

technical field [0001] The invention relates to a paint remover for removing paint, in particular to an environment-friendly water-based paint remover for removing paint on plastic surfaces, a preparation method and a use method thereof. Background technique [0002] At present, most of the paint strippers used to remove paint on plastic surfaces are organic solvents, such as cyclohexanone, dichloromethane, alcohols, etc. Although organic solvents have the advantages of high paint removal efficiency as paint removers, they have the following main disadvantages: [0003] 1. Serious pollution and great harm to human body, this is because organic solvents of benzene substances are more toxic to human body; [0004] 2. It also has a dissolution effect on plastics. It is not suitable to remove paint from plastic as the base material. It is also necessary to recycle the plastic base. However, some water-based paint removers are slow or even unable to remove the paint; [0005] 3...
