A method for controlling a network connection includes receiving a reset operation of a user, determining, in response to the reset operation, whether a smart household device is disconnected from a network. Creating a WI-FI hotspot based on a first WI-FI name and a first WI-FI password in response to the smart household device being disconnected from the network, where the smart household device has accessed the network based on the first WI-FI name and the first WI-FI password using a wireless access point (AP) before being disconnected from the network. Obtaining a second WI-FI name or a second WI-FI password, and sending the second WI-FI name or the second WI-FI password to the smart household device based on the WI-FI hotspot to enable the smart household device to re-access the network based on the second WI-FI name or the second WI-FI password using the wireless AP.

Method and device for controlling connection to network

Provided a wave-absorbing impregnation glue liquid, including: two-component epoxy resin, a solvent, a polyether siloxane, and a carbon powder; wherein a mass ratio of the two-component epoxy resin to the solvent is 1:3˜1:5, a mass ratio of the two-component epoxy resin to the carbon powder is 3:1˜6:1, and a mass fraction of the polyether siloxane in the wave-absorbing impregnation glue liquid is 0.05%˜0.2%. A wave-absorbing impregnation glue liquid, a wave-absorbing honeycomb and their preparation methods are further provided.

Wave-absorbing impregnation glue liquid, wave-absorbing honeycomb, and preparation methods thereof

The present disclosure provides an epoxy resin wave-absorbing composite material and a preparation method thereof. The method includes: heating an epoxy resin to 50&#xb0; C.&#x2dc;70&#xb0; C., and adding carbon black, to obtain a mixture of the epoxy resin and the carbon black; heating the mixture of the epoxy resin and the carbon black to 100&#xb0; C.&#x2dc;120&#xb0; C., adding a curing agent, and stirring and dissolving them to obtain a mixture of the epoxy resin, the carbon black, and the curing agent; and adding surface-treated hollow glass microbeads into the mixture of the epoxy resin, the carbon black, and the curing agent, and curing them to obtain the epoxy resin wave-absorbing composite material.
