Description

A flooring material comprising ground products of artificial marble wastes and a preparation method

The present invention relates to a flooring material comprising a ground product of flooring waste such as artificial marble, and a method of manufacturing the same. More particularly, the present invention relates to a flooring material comprising a ground material, resin, and filler of artificial marble waste, and a method of manufacturing the same.

In the case of recycling the waste material of the flooring material such as artificial marble and applying it to the flooring material again, there are advantages such as manufacturing cost reduction, and environmentally preferable in terms of reducing the amount of waste discharged. However, since flooring made of artificial marble waste or the like generally lacks durability and scratch resistance, in order to apply it as a real building material, it is possible to improve the durability and scratch resistance of the flooring material. Development of technology is desired.
