Problems solved by technology

[0002] Traditional indoor heating in winter mostly adopts centralized heating. The radiator is connected through indoor pipes or the pipes are directly laid under the floor tiles. The former heating method has the advantages of occupying a large space, severely restricting the layout, and affecting the appearance; the latter heating method Although the method overcomes the shortcomings of the exposed radiator, but the pipeline is laid under the floor tiles, once there is a water leakage problem, it will cause a lot of trouble
[0003] In order to overcome the above-mentioned defects, the improved heating device adopts the form of compounding heat-insulating materials on the ceramic tiles, but the ceramic tiles and the insulating materials are bonded and compounded with an adhesive. Once heated, the adhesive will be exposed to high temperature. When it is matured and fails, it will cause hollowing, cracking, even falling off, and delamination; there are also some ceramic floor heating tiles, which are installed with insulation boards first, and mortar and cement are placed on the insulation boards, and then tray-type heating tiles are laid. The method is not only very cumbersome and trivial to operate, but also the cement layer and insulation board will delaminate, fall off or uneven force will cause the insulation board to collapse after long-term use, and the bigger disadvantage is slow temperature rise, low heat storage, high energy consumption

Abstract

The invention discloses a production technology for an integrated tray type polyurethane heat-insulating heating tile. The production technology comprises the following steps: (1) putting a ceramic panel into a forming mold; (2) putting a tray containing a carbon fiber heating material on the back of the ceramic panel; (3) pouring a polyurethane foaming raw material into the forming mold, closing the mold, polymerizing polyurethane after 8-15min, opening the mold and taking out, thereby acquiring the integrated tray type polyurethane heat-insulating heating tile. The production technology has the advantages of simple process, high controllability and facilitation of large-scale production. The prepared floor heating tile has the advantages of long service life, convenience in mounting, high heating speed, high heat supply efficiency and attractiveness.
