A kind of degumming composition and its preparation method and application

Abstract

The invention discloses degumming composition. The degumming composition comprises components in percentage by mass as follows: 21% of dimethyl carbonate, 27% of diethylene glycol monohexyl ether, 47%of ethylene glycol monobutyl ether and 5% of water. The degumming composition is low in cost, short in degumming time and high in seepage force and degumming effect, produces little pollution, is non-corrosion to a matrix and is free of dead angles and residues, and by means of the degumming composition, technical support can be provided for development of an industrial cleaner.

Description

technical field [0001] The invention belongs to the field of industrial cleaning, and more specifically relates to a degumming composition and its preparation method and application. Background technique [0002] The parts of the circuit board are usually fixed with "red glue". Red glue is a kind of polyolefin compound, usually red, and sometimes yellow. It is widely used as a SMT material in the field of circuit boards. How to make the red gum come off more effectively is an industrial problem. [0003] In the prior art, chlorinated hydrocarbon solvents such as trichlorethylene are used for washing, but on the one hand, this detergent is highly toxic, and on the other hand, it has a corrosive effect on the substrate of the PCB board. At present, there is no industrial cleaning agent for red gum. Remover. Contents of the invention [0004] The object of the present invention is to provide a degumming composition according to the deficiencies in the prior art. The degumm...
