Problems solved by technology

[0009] Therefore, it is desired to develop a new method for insulating the fragments of the magnetic spacer to solve the problem that the insulating effect between the adjacent fragments in the strip after the split in the prior art is relatively poor and cause the magnetic spacer to generate relatively poor insulation during use. The big eddy problem

Embodiment 1

[0058] A magnetic isolation sheet, the preparation method is as follows:

[0059] Add 130g of silica sol into the beaker, then add 70g of polyurethane, 2g of silane coupling agent and 0.4g of surfactant, stir at 25°C for 2h, and finally make insulating glue.

[0060] Then take the split amorphous nanocrystalline ribbon MS1400, cut out 4 strips with a length of about 25mm, immerse them in the above insulating glue for a few seconds and slowly lift them out for drying; tear off the nanocrystalline ribbon after drying. A transparent release film on one side of the material is used, and then 4 sheets of nanocrystalline tapes are pasted and stacked together to obtain a magnetic isolation sheet.

Embodiment 2-3

[0062] The difference from Example 1 is that 90 g of silica sol and 110 g of polyurethane were added (Example 2), and 160 g of silica sol and 40 g of polyurethane were added (Example 3).

Embodiment 4-6

[0064] The difference from Examples 1-3 is that the silica sol is replaced by magnesium sol.

Abstract

The invention provides an insulating glue solution, a preparation method and an application thereof, and a separating magnetic piece obtained by using the insulating glue solution. 100 wt% of the insulating glue solution comprises 45-80 wt% of an aqueous inorganic nano-solution, 0.1-3 wt% of a modifier and 20-55 wt% of a film forming aid. The insulating glue solution can form an insulating glue layer on the surface of a band, and insulating colloid particles can permeate into a gap between adjacent fragment slits in the splintered band to form the insulating layer.

Description

technical field [0001] The invention belongs to the technical field of magnetic isolation sheets for wireless charging, and relates to an insulating glue, a preparation method and application thereof, and a magnetic isolation sheet obtained therefrom. Background technique [0002] Wireless charging technology (Wireless charging technology or Wireless charge technology) is derived from wireless power transmission technology, which means that a device with a battery does not need the help of electric wires, and uses the principle of electromagnetic wave induction or other related AC induction technology to be used at the sending end and the receiving end. A technology in which corresponding equipment sends and receives induced AC signals for charging. [0003] At present, the application of wireless charging technology in wearable devices, mobile phones, tablets and other terminal fields is mainly electromagnetic induction wireless charging technology. An alternating electrom...
