AI Technical Summary
In the existing technology, water-based cleaning solvents for car bumper painting equipment need to be purchased externally, which is costly and has a long transportation cycle, and it is difficult to adjust according to actual needs.
A water-based cleaning solvent was prepared by mixing isopropanolamine and ethylene glycol butyl ether in a 1:9 ratio and adding deionized water. This solvent was then used in automotive coating systems, thus enabling the production of a self-made cleaning solvent.
It reduces the procurement cost of cleaning solvents, improves the adjustability of cleaning effect, and reduces the risk of incomplete cleaning and the probability of particle generation.
Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile bumpers, and particularly relates to a method for synthesizing water-based paint cleaning solvent for automobile bumper spraying equipment. BACKGROUND
[0002] The water-based coating line cleaning solvent materials of existing host factories and part production factories are all purchased from Kluth, Axalta, PPG or NB transnational company products; the product unit price is relatively high, and the transportation cycle and product adjustability are restricted. SUMMARY
[0003] In view of the above problems, the purpose of the present application is to provide a method for synthesizing water-based paint cleaning solvent, which is used to reduce the procurement cost of water-based cleaning stock solution, so as to overcome the shortcomings of the above prior art.
[0004] The present application provides a method for synthesizing water-based paint cleaning solvent, characterized in that it comprises the following steps:
[0005] Step S1: isopropanolamine and ethylene glycol butyl ether are put into a dispersing stirrer according to a ratio of 1:9 for mixing to obtain a water-based cleaning solvent stock solution, wherein the stirring time of the dispersing stirrer is 30-60 minutes;
[0006] Step S2: the water-based cleaning solvent stock solution is put into a liquid storage tank of a cleaning system for automobile coating;
[0007] Step S3: deionized water is put into the liquid storage tank of the cleaning system for automobile coating, so that the deionized water and the water-based cleaning solvent stock solution are mixed and dispersed in the liquid storage tank for 30-60 minutes to obtain a water-based cleaning solvent.
[0008] As a preferred embodiment of the present application, the ratio of the deionized water to the water-based cleaning solvent stock solution is 95:5.
[0009] The present application has the advantages of greatly reducing the product procurement cost, and adjusting the cleaning effect by self-synthesis according to the actual cleaning effect, thereby reducing the risk of incomplete cleaning in the production process and reducing the probability of particle generation.
