Problems solved by technology

[0002] At present, the conventional heating rubber sheet uses a built-in electric heating wire to generate heat. The electric heating wire of this type of structure is easy to bend and break; for this reason, the company applied for the patent number ZL201620144786.9 in 2016. "Self-heating silicone plate", which weaves the heating wire into the fabric, effectively eliminates the bending and fracture of the electric heating wire, making it have a certain degree of flexibility; however, when the heating rubber sheet is used in an industrial environment, When it is stretched under pressure, the heating wire woven into the fabric will still break, thereby reducing product quality and affecting its service life

Abstract

The invention provides a heating glue plate preparation process. The preparation process comprises the steps that step1, a conductive rubber layer of a sheet structure is prepared; step2, Preparationof a heating chip is performed; and step3, the heating chip is hot-pressed and sealed into a seal sleeve. The step2 comprises the steps that step2.1, the conductive rubber layer of the sheet structureis compounded with a base plate to form a heating base bottom layer insulation glue plate; step2.2, the heating base bottom layer insulation glue plate is vulcanized by a vulcanizing machine to forma chip semi-finished product after metal strips taken as conductive electrodes are paved on the two sides of the heating base bottom layer insulation glue plate in the length direction of the heatingbase bottom layer insulation glue plate; and step2.3, a heating chip finished product is prepared after conductive wires are guided out from the metal strips of the chip semi-finished product. By means of the heating glue plate preparation process, the service life of a heating glue plate can be effectively prolonged.
