幅にコストアップになるという欠点がある。However, although the back layer portion in such a conventional tile carpet is excellent in dimensional stability, heat resistance and load resistance, it is formed by a filler mixed with a vinyl chloride resin. Weight increase occurs, and the original characteristics of tile carpet, such as ease of transportation and construction, are impaired.
Further, since the back layer portion is hardened, there is a problem such as lack of cushioning property. As a solution to this problem, there is an attempt to form the back layer with a foam layer, but the strength, morphological stability, slip resistance, and durability of the tile carpet are lost. There is also a proposal (Japanese Patent Publication No. 4-30850) that a part of the back layer part is formed by mechanical foaming, but it requires foaming equipment such as an oaks mixer and that a vinyl chloride paste sol Since the viscosity increases and heat is generated in the foaming machine to cause gelation, the filler can hardly be mixed, resulting in a significant cost increase compared to the conventional product.

ことを目的とする。On the other hand, in the tile carpet, in order to prevent the warp which is a problem during its construction, it is proposed to insert a woven fabric or a non-woven fabric composed of shrinkable fibers into the lower part of the back layer (Japanese Patent Publication No. 3-16536). However, there are drawbacks such as increased cost and complicated workability. It is an object of the present invention to provide a tile carpet that retains strength, shape stability, slip resistance, and durability, is lightweight, and prevents warpage.

活性化して１．１〜１．８倍の範囲で発泡させてある。The back layer 2 of the tile carpet is integrally formed by laminating a foam layer 6 of vinyl chloride resin, a glass fiber cloth layer 7, and a non-foam layer 8 of vinyl chloride resin in this order from the surface layer side. The foamed layer 6 comprises 70 to 100 parts by weight of a plasticizer and 300 parts by weight of an inorganic filler with respect to 100 parts by weight of polyvinyl chloride.
~ 500 parts by weight, 1 to 3 parts by weight of an organic foaming agent, and 1 to 3 parts by weight of a foaming stabilizer are added, and the organic foaming agent is activated by heating to foam in a range of 1.1 to 1.8 times. .

の公知のものが用いられる。The foam layer 6 of vinyl chloride resin is made of paste resin as polyvinyl chloride, and an unfoamed paste sol containing an organic foaming agent or the like is formed into a layer having a thickness of 1 to 3 mm by a coating method or the like. Afterwards, it is heated and solidified to form a foamed layer, but when the plasticizer to be blended is less than 70 parts by weight, the viscosity of the paste sol becomes too high and the workability such as coating deteriorates, and when it exceeds 100 parts by weight,
This may cause the product to become sticky, reduce the strength of the foam layer, and facilitate peeling from the surface layer. As the plasticizer, known ones such as dioctyl phthalate and diisononyl phthalate are used.

As a result, it becomes difficult to control the thickness due to excessive foaming, and the cost increases. As the organic foaming agent, azodicarbonamide, azobisisobutyronitrile, barium azodicarboxylate, dinitrosopentamethylenetetramine, P, P'-oxybisbenzenesulfonyl hydrazide, paratoluenesulfonyl hydrazide, etc. are used. .

To prevent the paste sol from increasing in viscosity, a liquid one is preferable,
A Zn-Na-based foaming stabilizer, a Zn-Ba-based foaming stabilizer, or the like is used. If it is less than 1 part by weight, the vinyl chloride resin has no thermal stabilizing effect, and if it exceeds 3 parts by weight, the cost becomes high.

工程は特に必要とはしない。The foam layer 6 of vinyl chloride resin provides cushioning properties and heat insulating properties to the tile carpet, and also contributes to weight reduction. Further, in order to secure load bearing capacity, the expansion ratio depends on the amount of the foaming agent and the heat foaming conditions. Is 1.1 to 1.8 times. Further, the foamed layer may contain an inorganic filler, a pigment or the like. The foamed layer is formed by forming an unfoamed paste sol into a layer by coating or the like, and then foaming and solidifying the paste sol by heating at the time of heating and gelling. Therefore, a foaming-only device or process is not particularly required.
