Special cleaning agent of environment-friendly water-based circuit board and preparation method of special cleaning agent

Abstract

The invention discloses a special cleaning agent of an environment-friendly water-based circuit board and a preparation method of the special cleaning agent. The special cleaning agent comprises the following components in weight percentage: 5%-30% of D-limonene, 2%-7% of a solubilizer,12%-30% of butyl cellosolve, 5%-10% of N-methyl pyrrolidone, 0.5%-5% of an emulsifying agent, 0.2%-0.5% of triethanolamine, 0.2%-0.4% of EDTA (Ethylene Diamine Tetraacetic Acid), 0.5-3% of a water-based quick-drying agent, 1.5%-4% of an addition agent and 20%-60% of deionized water. The special cleaning agent disclosed by the invention has the advantages that an environment-friendly requirement is met, the cleaning efficiency is high, and the special cleaning agent is suitable for rapidly cleaning resins, scaling agents, welding agents, thixotropic agents, thickening agents, active agents and other pollutants on the surfaces of various electronic circuit boards; the using temperature is 25 DEG C-38DEG C, and the special cleaning agent is directly cleaned under normal temperature and is also suitable for cleaning an ultrasonic washing machine.

Description

【Technical field】 [0001] The invention relates to a patent cleaning agent for electronic circuit boards and a preparation method thereof, in particular to an environmental-friendly water-based special cleaning agent for circuit boards and a preparation method thereof, belonging to the technical field of circuit board cleaning agents. 【Background technique】 [0002] With the rapid development of the electronics industry, the production of circuit boards is gradually expanding, and the demand for circuit boards will surely expand for a long time to come. Electronic circuit boards are divided into single-sided boards, double-sided boards and multi-layer boards. The residues after soldering printed circuit boards can be roughly divided into three categories: [0003] (1) Particulate pollutants - dust, lint and solder balls. [0004] (2) Non-polar pollutants - anti-oxidation oil used in flux, flux and wave soldering, as well as chemical substances left by the operator. [0005]...

AI Technical Summary

Problems solved by technology

[0008] 1. After cleaning, the surface of the board turns white, which affects the quality of the circuit board;

[0009] 2. The cleaning agent itself has residues on the board surface, which is not easy to remove;

[0010] 3. The low-temperature cleaning effect is poor, and the cleaning speed of resin oil stains is slow;

[0011] 4. The cleaning agent waste liquid treatment process is complicated, which is not conducive to environmental protection
