Abstract

The invention provides a heating cloth and a manufacturing method thereof. The manufacturing method comprises the following steps of arranging a first PU coating on a first side of a first PET substrate cloth, arranging a second PU coating on a first side of a second PET substrate cloth, printing silver slurry and carbon slurry on a second side of the second PET substrate cloth, pasting the first PU coating to the second side of the second PET substrate cloth, carrying out segmentation and carrying out connection with an electric wire. The manufacturing method utilizes PET as a substrate cloth and has simple processes and a low cost. The heating cloth is mute, can produce heat, has a controllable heating temperature, has high durability, has PTC effects and a temperature self-control function, is designed based on full understanding and utilization of a thermal expansion coefficient principle, is scientifically and reasonably provided with conductive electrode and heating carbon slurry layout and structure on the whole cloth base, can flexibly adjust carbon slurry resistance, has appropriate voltage and current values, successfully realizes heating cloth PTC effects, has temperature self-control function and has a high market application value.

Description

technical field [0001] The invention relates to a heating cloth, in particular to a heating cloth and a manufacturing method thereof. Background technique [0002] The heating sheets in the prior art usually use resistance wire, aluminum foil, stainless steel, PET base ink, etc., which do not have the PTC effect and have no self-temperature control function. If the wire is broken, it cannot be energized, and a short circuit generates a high current, causing fires and other disadvantages, or there is a danger of overheating. [0003] For example, Chinese patent 200410010358.9 discloses a heating cloth, which is a raw material cloth woven from polypropylene fiber, viscose fiber, pitch fiber, phenolic fiber, polyvinyl alcohol fiber or polyvinyl chloride fiber, and is prepared according to the following steps Formation: the first step, arrange the above-mentioned raw materials in a vacuum state of 0.1-0.3Pa, and carry out pre-oxidation treatment at a temperature between 250-300...
