Problems solved by technology

Some paint strippers currently available in the market are highly toxic, their stability cannot meet the requirements, their storage time is not long, and they cannot be used repeatedly or the paint stripping effect will be greatly reduced when they are used repeatedly. Some acidic paint strippers or alkaline strippers Paints are highly corrosive to metals and have high requirements for operational safety, so they are not suitable for large-scale promotion and use

Abstract

The invention provides a mechanical de-painting method which comprises the following steps: (1) spraying a de-painting liquid onto a mechanical surface, wherein the spraying amount is 1.2-1.5kg / m<2> and the temperature of the de-painting liquid is 70-75 DEG C; (2) after spraying the de-painting liquid for 10-15min, uniformly coating a de-painting agent on the mechanical surface, wherein the dosage is 1.3-1.5kg / m<2> and the temperature of the de-painting agent is 50-60 DEG C; and (3) after coating the de-painting agent for 3-4min, washing the mechanical surface with water and then uniformly scattering the mixed sand on the mechanical surface. According to the mechanical de-painting method provided by the invention, the de-painting effect is obvious and the de-painting speed is high; in a de-painting process, the volatile pungent odor is less, so that the health of the operator can be guaranteed; the corrosive property of the de-painting agent is lower and the substrate surface is almost not corroded; the stability of the de-painting agent is higher; the de-painting agent can be stored for a long time; the de-painting liquid, the de-painting agent and the mixed sand adopted according to the invention all can be collected and then reused; the pollution to environment is greatly reduced; and when the materials are reused, the de-painting property is still excellent.

Description

technical field [0001] The invention belongs to the field of mechanical renovation, and in particular relates to a mechanical paint stripping method. Background technique [0002] The coating on the mechanical surface can effectively slow down the aging speed of the mechanical surface, but in the process of use, the coating film will be damaged or gradually aged, and then lose the function of protecting the mechanical surface, or it needs to be renovated for aesthetic considerations. Renewal, the first step in the renovation and renewal of the mechanical surface is to remove the paint on the original mechanical surface, so that the repainting can proceed smoothly. The use of paint remover is a method commonly used for mechanical surface paint removal. Some paint strippers currently available in the market are highly toxic, their stability cannot meet the requirements, their storage time is not long, and they cannot be used repeatedly or the paint stripping effect will be gr...
