preparation example Construction

[0021] The preparation of the cleaning agent composition of the present invention is simple, and can be obtained by uniformly mixing various components forming the cleaning agent composition by conventional methods.

[0022] According to the present invention, the method for cleaning the black hole carbon powder preferably comprises dissolving the black hole carbon powder cleaning agent composition in a solvent to obtain a uniform cleaning agent composition solution, and then applying the solution to the surface of the substrate. After fully functioning, gently wipe the surface of the polyimide film with a dust-free cloth to completely wash off the toner. The method of applying the obtained solution to the surface of the substrate is preferably soaking the substrate with the solution. There is no special limitation on the amount of the solution. The substrate can be completely immersed in the solution, or only the black hole carbon powder that needs to be cleaned can be soaked ...

Embodiment 1

[0032] This example is used to illustrate the black hole toner cleaning agent composition provided by the present invention, its preparation method and the cleaning method of black hole toner.

[0033] 30 parts by weight of sodium dodecylbenzene sulfonate, 5 parts by weight of sodium tripolyphosphate and 2 parts by weight of carboxymethyl cellulose were uniformly mixed to prepare black hole toner cleaning agent composition S1.

[0034] All the above compositions were compounded with 1000 parts by weight of deionized water, and stirred evenly to prepare a cleaning agent composition solution. Immerse all the polyimide film adhered with carbon powder in the obtained cleaning agent composition solution for 5 minutes, then gently wipe the surface of the polyimide film with a dust-free cloth to remove the carbon powder particles, and then spray the film in sequence. After water washing, acid washing, spray washing and drying, the polyimide film was taken out and observed under a mic...

Embodiment 2

[0036] This example is used to illustrate the black hole toner cleaning agent composition provided by the present invention, its preparation method and the cleaning method of black hole toner.

[0037] 25 parts by weight of stearyl alcohol polyoxyethylene ether, 8 parts by weight of sodium hexametaphosphate and 3 parts by weight of carboxymethyl cellulose were evenly mixed to prepare black hole carbon powder cleaning agent composition S2.

[0038] All the above compositions were compounded with 1200 parts by weight of deionized water, and stirred evenly to prepare a cleaning agent composition solution. Immerse all the epoxy glass fiber cloth with carbon powder adhered in the obtained cleaning agent composition solution for 10 minutes, then gently wipe the surface of the epoxy glass fiber cloth with a dust-free cloth to remove the carbon powder particles, and spray them in turn After water washing, acid washing, spray washing and drying, the polyimide film was taken out and obs...

Abstract

The invention relates to a black hole carbon powder cleaning agent combination, wherein, the combination contains surfactant, emulsion dispersant and metal complexing agent that is contained selectively. One sort or a plurality of sorts of anionic surfactant, non-ionic surfactant and complex anionic and non-ionic surfactant is/are taken as the surfactant. The black hole carbon powder cleaning agent combination provided by the invention can effectively remove the black hole carbon powder on the surface of the organic materials (e.g. polyimide film, epoxy adhesive, acrylic resin adhesive and epoxy glass fibre cloth) at the surface of various base materials, e.g. a printed-circuit board without causing any unfavorable influence to the base materials.

Description

technical field [0001] The present invention relates to a cleaning agent composition and its usage method, in particular to a black hole carbon powder cleaning agent composition and a cleaning method of black hole carbon powder. Background technique [0002] Flexible printed circuit board (FPC) is composed of thin film, which has obvious advantages such as flexible structure, small size and light weight. It can improve the freedom and flexibility of circuit design and mechanical structure design, enable wiring on X, Y, and Z planes, and reduce interface connection points, which can not only reduce the workload of the whole machine and assembly error rate, but also greatly improve the overall electronic performance. The reliability and stability of the equipment system have been widely used. The application fields of FPC mainly include applications in computers, communication machines, instrumentation, medical equipment, military and aerospace. [0003] With the continuous ...
