preparation example 6

[0061] A heating agent, made of the following raw materials in parts by weight: 12g Al powder; 10g activated carbon;

[0062] A preparation process of exothermic agent specifically comprises the following process steps:

[0063] Take Al 2 o 3 Raw material, the Al 2 o 3 The raw materials were mechanically crushed and sieved with a 400-mesh sieve to obtain Al 2 o 3 powder, and then use hydrogen to Al 2 o 3 The powder undergoes hydrogenation reduction reaction to obtain Al powder with rough surface and spongy holes inside. Inert gas nitrogen is introduced into the Al powder, and then the particle size is added to the Al powder while maintaining the inert gas nitrogen. Activated carbon particles of 200 μm were filled with Al powder into the pores of the activated carbon particles to obtain a heat generating agent.

Abstract

The invention relates to the technical field of thin film electronic devices, and particularly discloses a touch switch with a 3D effect. The touch switch with the 3D effect comprises a pattern layer, a base material and a touch switch circuit which are sequentially arranged, the touch switch circuit is sequentially provided with conductive oil, carbon paste, a silver paste circuit and a transparent insulating layer in the direction from the pattern layer to the base material, and the pattern layer or the transparent insulating layer is provided with an adhesive layer. According to the touch circuit, by adding the transparent insulating layer and the conductive oil, compared with an original mode that an upper-layer contact of the control circuit is in contact connection with a lower-layer polar plate of the control circuit, the situation that contact is insufficient after the contact and the polar plate are in contact for multiple times is avoided, the capacitive touch effect is achieved through the conductive oil, the touch circuit is controlled by changing the capacitance, and the service life of the touch switch can be prolonged to a certain extent.

Description

technical field [0001] This application relates to the technical field of thin film electronic devices, more specifically, it relates to a touch switch with 3D effect. Background technique [0002] Membrane switch is an operating system that integrates button functions, indicating elements, and instrument panels. It is made of several layers of films of different materials bonded into a finished product. The thickness is about 1.2-2.5mm, and it has the dual functions of the panel and the switch. Due to the short action stroke of the membrane switch, which is only about 0.25-0.5mm, and the switch pressing force is 0.5-1N, it is relatively sensitive, and the switch function is completed with a light touch of the hand, so it is also called a touch switch. The touch switch is well sealed, has the characteristics of moisture resistance and long service life, and is widely used in electronic measuring instruments, automobile industry, household appliances and other fields.
