Tile carpet

Abstract

A carpet of a type to be used in such manner that square plate-like members having a predetermined size are laid over the floor, and more particularly, a tile carpet comprising a carpet body, a carpet base to which the carpet body is fixed, and a layer of non-hardening type adhesive arranged on the rear surface of the carpet base, characterized in that the non-hardening type adhesive layer of the tile carpet consists of a mixture of acrylic foaming resin and urethane resin hardening type adhesive and a ratio of mixing of urethane resin hardening type adhesive in the mixture is 10 to 30 weight %.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the invention[0002]The present invention relates to a tile carpet, which is to be laid or put on over the surface of a floor covered with many long wood strips engaging with one another without gaps, a floor finished at the surface with mortar, a floor fully covered with plastic plates, or a floor formed with fully laid plates of natural stones, or the like. The tile carpet may be merely put on, so that it does not tend to have slip between the tile carpet and the floor surface, and the tile carpet when removed does almost not have marks of an adhesive on the floor surface.[0003]An adhesive of hardening type is in the state of liquid having fluidity when in use for adhering tile carpets on the floor and is capable of being readily contacting with an object to be adhered and of wetting it. Then, the adhesive changes into solid through heating and / or chemical reaction, so that it shows a strong connection at the interface and an effect of r...

AI Technical Summary

Benefits of technology

The present invention is a high-quality tile carpet with several advantages. The layer of adhesive is made up of a mixture of acrylic foaming resin and urethane resin hardening type adhesive with a ratio of 10-30 weight%. This results in low adhesiveness, meaning the tiled carpet will not leave any marks when peeled off after use. This adhesive mixture also allows for easy manufacturing, transporting, and preserving of the carpet without the need for additional exfoliation paper. Additionally, even when made as a washable type, the carpet still maintains its function and effectiveness over time, making it suitable for repetitive use.

Problems solved by technology

Also, even the case not making repetition of laying over and removing the tile carpets, since it is not strong bonding using the hardening type adhesive, it is quite suitable for such case that any single piece of tile carpets laid over the floor is notably stained or broken to be replaced with a new piece of tile carpet.

When the hardening type adhesive has been applied, working of amending by replacing only one piece of tile carpet is hard to be carried out.

However, practically, when tile carpets laid over the floor in autumn are removed in the next spring, marks of the non-hardening adhesive are left on the floor, leading to troubles of removing the marks, and occasionally the marks cannot at all be removed.

Also, when tile carpets which had been laid over the floor last autumn are newly laid over, it is found to have lost slip resistance.

A small foreign force such as walking motion causes the tile carpets to slip and be shifted in position easily, leading to poor appearance and further presumably problems of security and safety and those related to Product Liability Act (Act No. 85 of 1994).

However, the adhesive applying method still has not reached a fundamental solution.
