Functional mortar composition using lead stone and massato suitable for construction finishing materials or bike-only roads and making method thereof

The present invention relates to a functional mortar composition using pyrophyllite and Masato suitable for a construction finishing material or a bicycle road, and a method for manufacturing the same, and more particularly, it is suitable for a construction finishing material or a binder for a bicycle road pavement, and foreign substances when exposed to light Since it contains an adsorbent to adsorb, it relates to a functional mortar composition using pyrophyllite and masato suitable for a finishing material for construction or a bicycle-only road that can implement a function of preventing environmental pollution when used in a construction finishing material or a bicycle-only road, and a method for manufacturing the same.

Generally used building finishing materials are multilayer composite materials or aluminum laminated with wood plywood and synthetic resin panels to increase rigidity, but this has a problem in that the weight increases.

Accordingly, the development of a new building finishing material that is lightweight while having a flame retardancy is being attempted.

For example, in Korean Patent No. 10-1552542, as a sheet-like finishing material having a flame retardancy, 5 to 30 parts by weight of a flame retardant, 0 to 100 parts by weight of a filler (excluding 0), an anti-blocking agent 0.4 based on 100 parts by weight of a polypropylene resin Disclosed is a polypropylene film layer comprising ~5 parts by weight, 0.2 to 3 parts by weight of a lubricant, and 0.1 to 1 parts by weight of a stabilizer.

However, the above document relates to a sheet-like finishing material having a flame retardancy, and there is no disclosure on rigidity and weight reduction.
