A surface treatment composition of the present invention comprises (A) urethaneacrylate oligomer, (B) acrylate based monomer, (C) photoinitiator, (D) silicon additive, and (E) silica matting agent. The present invention provides a surface treatment composition in which imparts abrasion and scratch resistance to the surface of a soft type urethaneacrylate oligomer decorative floor covering, and ameliorates the problem of low stain resistance caused a low density of elaborate crosslinks by using a small amount of single functional group monomer. The present invention also provides a surface treatment composition in which employs only hard type urethaneacrylate without single functional group monomer so that cross linking density is increased and the effects of oxygen that prohibits the surface curing are minimized, resulting in improved stain resistance. Additionally, this invention provides a surface treatment composition in which a mixture of soft type and hard type urethaneacrylate oligomer and a mixture of acetophenone and benzophenone photoinitiator are used, and a tertiary amine compound reaction promoter is added. Furthermore, this invention provides a surface treatment composition in which mixed soft and hard type urethaneacrylate oligomer is used, acetophenone photoinitiator is added, and ultraviolet light (UV) curing is performed under a nitrogen gas environment. The stain resistance of a decorative floor covering in which a surface treating sub-layer is formed by UV curing after an above surface treatment composition is coated is excellent.

This application is based on application No 10-1999-0008262 filed in the Korean Industrial Property Office on Mar. 12, 1999, the content of which is incorporated hereinto by reference.
(a) Field of the Invention
The present invention relates to a surface treatment composition, a decorative floor covering, and a method for manufacturing the same, and more particularly, to a polyurethane based surface treatment composition having excellent stain resistance, a decorative floor covering of which the surface is treated by this composition, and a method for manufacturing the same.
A more complete appreciation of the invention, and many of the attendant advantages thereof, will be readily apparent as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, wherein;
FIGS. 1a to 1d are cross-sectional views of a decorative floor covering in accordance with the present invention.
FIG. 2 is a manufacturing process diagram of a decorative floor covering in accordance with the present invention.
In the following detailed description, only the preferred embodiment of the invention has been shown and described, simply by way of illustration of the best mode contemplated by the inventors of carrying out the invention. As will be realized, the invention is capable of modification in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not restrictive.
The present invention relates to a stain resistant polyurethane based surface treatment composition comprising (A) urethaneacrylate oligomer (B) acrylate based monomer (C) photoinitiator, (D) silicon additive, and (E) silica matting agent; a decorative floor covering in which a stain resistant surface treating sub-layer is formed by coating the above surface treatment composition and ultra violet light (UV) curing; and a method for manufacturing the same. This invention is described in detail below.
In the preferred embodiments of the present invention, a surface treatment composition provides abrasion resistance and scratch resistance on the surface of a decorative floor covering using soft type urethaneacrylate oligomer, and ameliorates the lowered stain resistant problems due to a low density of elaborate cross-links by employing small amounts of single functional group monomer. The above surface treatment composition is comprised of (A) 40 weight parts of soft type urethaneacrylate oligomer, (B) acrylate based monomer comprising 7 to 11 weight parts of single functional group monomer, 34 to 43 weight parts of bi-functional group monomer, and 0 to 5 weight parts of acrylate based tri-functional group monomer. (C) 4 weight parts of acetophenone photoinitiator, (D) 1 weight part of silicon additive, and (E) 5 weight parts of silica matting agent.
