| titleOfInvention | Steel plate release agent for PCB multi-layer board laminating process |
| abstract | The invention discloses a steel plate release agent for a PCB multi-layer board lamination process, which is prepared by uniformly mixing 1-7 wt% of polyquaternary ammonium salt, 1.0-5.0 wt% of siloxane, 2-10 wt% of polyolefin wax emulsion and the balance of deionized water in a pure liquid form, and when the release agent is used, a lamination steel plate is soaked in the release agent and then taken out for drying, so that a uniform solid release layer can be formed on the surface of the steel plate, direct contact between resin and the steel plate can be effectively prevented, the release effect is good, the resin particle residue is reduced, the lamination depression ratio is reduced, and the product yield of a lamination process can be improved; and after the use, the resin particles are conveniently removed by adopting a brushing and grinding mode, the resin particles are not remained, the used waste liquid can be treated according to the common waste water after being filtered, and the environmental pollution is small. |
