Abstract

The invention discloses a spray-type normal-temperature high-efficiency degreaser which comprises the following components in percentage by mass: 0.1-0.8% of potassium hydroxide, 0.5-1.5% of sodium hydroxide, 10-15% of potassium metasilicate pentahydrate, 10-15% of sodium tripolyphosphate, 1-8% of borax decahydrate, 15-53% of sodium carbonate, 1-4% of sodium gluconate, 0.5-1.3% of JFC, 0.1-0.6% of special low-foaming surfactant Y-36 for spray degreasing, 0.1-0.6% of special low-foaming surfactant Y-39 for spray degreasing, 0.1-0.2% of defoaming agent and the balance of water. The preparation method comprises the following steps: adding calculated and weighed water into a reaction kettle; sequentially and slowly adding calculated and weighed sodium carbonate, sodium tripolyphosphate, borax decahydrate, sodium gluconate, potassium metasilicate pentahydrate, potassium hydroxide, sodium hydroxide, JFC, special low-foaming surfactant Y-36 for spray degreasing, special low-foaming surfactant Y-39 for spray degreasing and defoaming agent; and evenly stirring.

Description

technical field [0001] The invention relates to a cleaning agent used before spraying and painting and a preparation method thereof, in particular to a spray-type normal-temperature high-efficiency degreasing agent with low cost and good degreasing effect and a preparation method thereof. Background technique [0002] Cleaning technology will be applied in various industrial productions, that is, using cleaning equipment and cleaning agents to carry out cleaning, including ultrasonic cleaning, steam cleaning, high-pressure cleaning, ozone-ultraviolet cleaning, ion beam cleaning and plasma cleaning. At present, spray cleaning is required before the workpiece is sprayed and painted. The process is as follows: degreasing→main degreasing→assistant degreasing→water washing→water washing→film formation→water washing→water washing→pure water washing→drying→download electrostatic spraying Pack. Existing cleaning agents need to be heated to 50°C during pre-degreasing, main degreasin...
