Abstract

The invention provides an efficient and clean electronic material cleaning agent and a preparation method thereof. The preparation method is as follows: (1) Mix aloe extract, reed root polysaccharide, Dendrobium officinale polysaccharide, sodium citrate, ascorbyl palmitate, thymol, calcium phosphate, polyethylene glycol and deionized water, and stir for 10‑20 minutes ; (2) Add water-based polyurethane and stir for 20-40 minutes at a temperature of 40-50°C; (3) Raise the temperature of α-methyl cyanoacrylate to 40-50°C; (4) Mix the above components, Stir at 50-60°C for 30-60 minutes. The high-efficiency and clean electronic material cleaning agent of the present invention has high tensile shear strength, good viscosity and fast curing speed, and at the same time, the adhesive has good bacteriostasis.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to an efficient and clean cleaning agent for electronic materials and a preparation method thereof. Background technique [0002] With the rapid development of modern electronic materials in the direction of short, small, light and thin and the increase in product complexity, more and more non-polar pollutants (rosin resin and oil, etc.) have been introduced into the electronic manufacturing process , polar pollutants (flux activator and salt, etc.) and particulate pollutants, if these pollutants are not removed in a timely and effective manner, it will directly cause leakage, short circuit, open circuit or corrosion on the surface of printed boards and components Leading to failure will inevitably affect the smooth implementation of the process or the quality and reliability of the product. Therefore, it is necessary to introduce cleaning procedures in many links of process implemen...
