Problems solved by technology

Halogen-free cleaning agents are mainly composed of alcohols, ketones, ethers, esters, alkanes and other low-flash point, low-boiling point solvents. This type of cleaning agent has the advantages of low cost and fast drying speed, but it also has cleaning performance Not as good as chlorofluorocarbons, which are highly destructive to the environment and human health, highly volatile, low flash point and explosive, etc.

Abstract

The present invention provides a method of preparing a circuit board water base washing agent.The preparation method is as follows: (1) Park the raw material according to weight; (2) Add benzonyzol, tinhol polyxoline ether, D‑ lemonine, ethyl acetico, ethanlamine, duolinel group in the reaction kettleAlcoholic polyoxide ether carboxylic acid, ethanol, mixing 5‑20min; (3) Continue to add isopropanol, monocycal polyoxide, nitrobacol, cinnamol ether phosphoricate, and be fully stirred and evenly stirred15‑25min; (4) Finally, add sodium sodium hydroxyyl for fork fork and ionic water, oscillation of 20‑35min in the ultrasonic, and settled filtration.The circuit board water base washing agent of the invention is smaller on the human and environmental side effects, and the cleaning efficiency is high. It is suitable for the SMT circuit board printing residual tinnut paste and red glue residue, especially the electronic components and welding pollution contaminated by rubber marks.Cleaning application of printed circuit boards.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a preparation method of a circuit board water-based cleaning agent. Background technique [0002] In the past ten years, my country's printed circuit board (Printed Circuit Board, referred to as PCB) manufacturing industry has developed rapidly, and its total output value and total output both rank first in the world. Due to the ever-changing electronic products, the price war has changed the structure of the supply chain. China has both industrial distribution, cost and market advantages, and has become the most important production base of printed circuit boards in the world. With the rapid development of the electronics industry, in today's emphasis on integration, intelligence, and simplification, there are more and more electronic components on the circuit board, and the size of the circuit board is getting smaller and smaller. During the process, it is inevitable that solder paste or re...
