Problems solved by technology
The anti-static effect of traditional gas meters is poor, and it is easy to affect the gas value display. The flame retardant effect of the shell and the dial is not good, accidents are prone to occur, and the protection is not good, and the service life outdoors is short. Therefore, an intelligent meter is needed. Gas meter multi-layer board and its preparation process

Abstract
The invention discloses a multilayer board for an intelligent gas meter and a manufacturing method thereof. The multilayer board comprises a multilayer board body, wherein the multilayer board body comprises a substrate arranged in the middle part of the multilayer board body; the inner surface and the outer surface of the substrate are connected with heat insulation plates through bonding layers;a flame-retardant layer is connected with and arranged out of the outer heat insulation plate through a bonding layer; a metal shielding layer is arranged in and connected with the inner heat insulation plate through another bonding layer; and an optical plastic protective coating is arranged outside the metal shielding layer and the flame-retardant layer. The manufactured multilayer board has excellent flame retardant and heat insulation effects, anti-static performance, good protection performance, good light transmission performance, high wear resistance and high hardness; and the manufacturing method is simple in process, easy to implement and worthy of promotion.
Description
technical field [0001] The invention relates to the technical field of dials, in particular to an intelligent gas meter multilayer board and a preparation process thereof. Background technique [0002] From the outside of the gas meter, only a scroll wheel with numbers can be seen in the small glass window. There are also seven digits on the scroll wheel, the first four digits of the decimal point are black, and the last three digits are red. People's daily cooking fuels have changed from conventional energy such as firewood and coal, which are wasteful and polluting, to natural gas, coal gas, and even electricity. The gas meter will play its role here. Its automatic accumulation function enables those who use natural gas or piped gas to know how much gas they have used so that they can pay according to the cubic meters of gas consumed every month. The anti-static effect of traditional gas meters is poor, and it is easy to affect the gas value display. The flame retardant e...
