Method of manufacturing an insulating floor material and an insulating floor material manufactured by the manufacturing method

The present invention relates to a heat insulating flooring and a building flooring manufactured by the manufacturing method, and more particularly, to a method for producing a heat insulating flooring material excellent in heat insulating properties and endothermic properties, and a heat insulating flooring material produced by the manufacturing method.

In general, insulators are used to block heat from the outside or to prevent heat from being emitted inside.

These insulations reduce heat transfer and reduce heat loss or heat gain, thus saving energy.

Styrofoam, which is superior to other insulation materials in terms of processing and price, is generally used as a heat insulating material for buildings. Such styrofoam is a foamed synthetic resin that prevents sound insulation and insulation while being attached to the interior, exterior wall, ceiling, or floor of a building. Function.

However, when the heat insulating material is installed on the floor, the heat exchanger tube for heating is installed on the floor surface of the building, and after the heat exchanger tube for heating is applied and cured mortar thereon, a separate foamed synthetic resin is laminated. In addition, the overall thickness of the bottom surface becomes thick, and heat of the heat exchanger tube is not properly transferred to the flooring material through the foamed synthetic resin, so that the overall construction cost is high, and the heating effect and the function of the insulation are deteriorated. There was this.
