Polyurethane has been applied to a wide range of industrial fields such as elastomers, paints, adhesives, fibers, leather, soft and hard foams and flooring. Polyols used as raw materials for such polyurethanes have industrially important values. Generally, petroleum-based synthetic polyols such as polyester-based polyols and polyether-based polyols are mainly used for polyurethane synthesis. However, due to rising oil prices and environmental problems, many studies are under way to replace petroleum-based synthetic polyols. In particular, research on synthesis of polyurethane based on vegetable oil has recently been reported [Petrovic Z. S. "Polyurethanes from Vegetable Oils" Polym. Rev., 2008; 48 (1): 109-155, Kong X., Narine S. S. "Physical Properties of Polyurethane Plastic Sheets Produced from Polyols from Canola Oil" Biomacromolecules, 2007; 8 (7): 2203-2209).

Polyurethane resin flooring materials are widely used because they have abundant elasticity, high mechanical strength, and excellent abrasion resistance. However, they are generally hard to use and are suitable for use in fire-fighting and meat processing plants requiring high strength floors not. In addition, if there is a certain amount of water on the floor surface to be used as a flooring material, the flooring construction work can not be performed and there is a weak point of heat. In particular, due to the characteristics of the flooring material containing the polymer resin, the curing takes place after a certain period of time, which makes the work impossible, and the time until the work is possible, that is, the working time is short, And the like have been pointed out.

The present application is directed to a biopolymer flooring composition comprising a modified plant-derived polyol and a process for preparing the same.

The biopolymer flooring composition according to the present invention can be obtained by mixing a polyurethane resin with an inorganic flooring material by using a modified vegetable oil-based polyol, thereby obtaining high mechanical properties and waterproofing properties, which are advantages of a polymer flooring material, And the flooring composition having both of the flame retardant properties can be produced. The process for preparing a biopolymer flooring composition according to the present invention is environmentally friendly compared to petroleum-based polyols using vegetable oil-based polyols and no solvent or heavy metal catalysts at all.

By using the modified vegetable oil-based polyol, the biopolymer flooring composition according to the present invention can solve the problem of elasticity degradation that may occur when the vegetable oil-based polyol is used alone, and the problem of shortening the working time when the flooring material is applied .
