Abstract

The invention provides an inorganic flat warmer and a manufacturing method thereof. A plastic concrete slurry is poured outside a flexible grid heating plate for the inorganic flat warmer provided by the invention; the upper layer of the flexible grid heating plate is provided with a first grid cloth or the lower layer of the flexible grid heating plate is provided with a second grid cloth, and the plastic concrete slurry is laid on the lower layer of the first grid cloth or the upper layer of the second grid cloth; or the upper layer and the lower layer are respectively provided with the first grid cloth and the second grid cloth, and the plastic concrete slurry is respectively laid on the lower layer of the first grid cloth and the upper layer of the second grid cloth. According to the invention, the flexible grid heating plate is adopted as a heating body, and the warmer is conveniently laid down, and is suitable for the temperature conservation in different occasions; and grid clothes made of different materials are adopted for fixation, and the requirement on using in different temperature conditions can be met.

Description

technical field [0001] The invention relates to the field of heaters, in particular to an inorganic panel heater, a preparation method thereof and plastic concrete used for heating the inorganic panel. Background technique [0002] Heaters are widely used in residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages and other mobile heating, simple mobile homes and other civil and public buildings. Heaters mainly transfer heat through conduction and radiation principles. Most of the common electric blankets, heaters, and far-infrared heaters on the market have shortcomings such as unstable quality, short service life, slow temperature rise, high power consumption, and loud noise. [0003] At present, it is very popular to use heating element of heating cable as heating material. The inner core of heating cable is composed of cold wire and hot wire, and the outside is composed of insulating layer, grounding layer, shielding layer and outer she...
