The carpet tiles used as the flooring material mentioned above are used in stores, offices, residences, etc. where they are used.
Although various structures have been proposed depending on the type of business, the basic structure generally includes an upper surface layer made of fiber material and a backing layer laminated on the back side of this layer. The upper surface layer emphasizes design aesthetics and tactile functions such as colors and patterns, while the backing layer has the appropriate thickness and strength of carpet tiles, anti-slip properties on floors, and heat resistance and durability. features are highlighted. Therefore, the upper surface layer is formed by using one or more types of natural fibers, synthetic fibers, or semi-synthetic fibers, and further mixed with glass fibers, carbon fibers, or metal fibers, and the backing layer is formed using bitumen-based or polyvinyl chloride-based materials. Consideration has been taken to make frequent use of

However, the polyvinyl chloride packing material used as the backing layer of tile carpet, and the glass fiber layer that is laminated to the backing layer for dimensional stability, have dimensional stability, heat resistance, and load resistance. However, due to the high density of polyvinyl chloride itself and the high content of fillers, it causes an increase in weight.
This results in impairing the ease of transportation and installation, which are the main objectives of tile carpets, and on the other hand, the backing layer is hard, resulting in a lack of cushioning properties.

ある。 Therefore, attempts have been made to form a foam layer on the backing layer to eliminate the above drawbacks. However, if the backing layer is simply formed from a foam layer,
Even if it is possible to make carpet tiles lightweight (transportability) and cushioning properties, on the contrary, the strength (load-bearing capacity), dimensional stability, slip resistance,
Furthermore, durability etc. will be lost. Therefore, the present invention solves the above-mentioned contradictory situation by laminating a foamed layer on the backing layer, a glass fiber cloth that supports it from below, and a non-foamed layer on the backing layer. At the same time, the present invention aims to provide a highly practical tile carpet by setting the blending ratios of the foamed layer and the non-foamed layer that supports it to the most appropriate values.

The present invention is roughly divided into an upper surface layer made of a fiber material and a backing layer laminated on the back side of the upper surface layer, and further, the backing layer is made of glass between a foamed layer as an upper layer and a non-foamed layer as a lower layer. The foam layer is laminated with fiber cloth interposed therebetween, and the foamed layer contains 40 to 120 parts by weight of a plasticizer and 0 to 100 parts by weight of an inorganic filler based on 100 parts by weight of polyvinyl chloride.
It is formed by flowing compressed air into a paste sol containing 100 parts by weight, 2 to 4 parts by weight of a liquid stabilizer, and 1 to 8 parts by weight of a silicone foaming agent, and mechanically foaming it to 1.5 to 4 times the size. The present invention is also characterized by a tile carpet in which the non-foamed layer contains 300 to 500 parts by weight of an inorganic filler based on 100 parts by weight of polyvinyl chloride.

According to the above means, the foam layer in the backing layer together with the upper surface layer made of fiber material guarantees the lightness and cushioning properties of the tile carpet itself, making it easy to transport and install the tile carpet, and It is possible to create a soft feel when stepping on the foot, and
By interposing a glass fiber layer under the foam layer, the thickness of the foam layer can be made uniform during formation, preventing unevenness on the carpet surface, and forming a flat surface that is easy to walk on. In addition, the bottom non-foamed layer of the backing layer acts as a base layer for the entire carpet tile, imparting adequate strength and heat resistance to the carpet and extending its lifespan.
Prevents carpet peeling by maintaining good adhesion to the floor surface.

ある。 According to experiments, the polyvinyl chloride foam layer 5 contains 100 parts by weight of polyvinyl chloride paste range.
Compressed air is added according to the expansion ratio into a paste sol containing 40 to 120 parts by weight of a plasticizer, 0 to 100 parts by weight of an inorganic filler, 1 to 8 parts by weight of a silicone foaming agent, and 2 to 4 parts of a liquid stabilizer. Quantitatively injected mechanically 1.5
~4 times the foam is desirable, 0.3~0.8
It has a density of g/cm 3 and is coated with a thickness of 1.5 to 5 mm. In addition, in each of the above compounding ratios, if the amount of plasticizer is less than 40 parts, the viscosity of the paste sol will become too high, generating a large amount of heat in the OAKS mixer and easily gelling in the mixer, and if the amount of plasticizer is more than 120 parts, the paste sol will become too thick. This is because it is not absorbed sufficiently by the PVC resin, causing the product to become sticky, reducing the strength of the foam layer, and causing peeling of the upper surface layer. In addition, it is preferable to increase the amount of inorganic filler in order to reduce costs, but if it exceeds 100 parts, the viscosity of the paste sol will increase, causing gelation due to heat generation in the oak mixer, and the strength of the foam layer after the product is finished. This is because the upper surface layer tends to peel off due to the lowering, and the density increases, which hinders weight reduction.
Furthermore, regarding the silicone foaming agent, this is a foaming sol that is mechanically foamed by flowing compressed air into the paste sol, and then coated to prevent the foam from collapsing until the upper surface layer is bonded. If the amount is less than 1 part, the foam stabilizing effect will be small and it will collapse easily, and the specified foaming ratio cannot be stably obtained, and if the amount is more than 8 parts, the foam stabilizing effect will not change, and The cost will be high. Next, stabilizers are commonly used to prevent deterioration due to heat during manufacturing and use, but to prevent increases in viscosity, liquid stabilizers are preferred; This is because the number of copies is not sufficient, and if there are more than four copies, the cost will be high. And the foaming ratio is
The reason why the ratio is 1.5 to 4 times is because if it is less than 1.5 times, the expected effect of cushioning properties and weight reduction cannot be obtained, and if it is more than 4 times, the strength of the foam will decrease, causing peeling of the upper surface layer and weakening of the foam layer. This is because it becomes larger.
そして、上記配合比……によれば、該発泡層５

ツトを適度に軽量化する。 According to the above compounding ratio..., the foam layer 5
It exhibits good functions for carpet tiles, especially in terms of cushioning properties and heat insulation properties, and also makes the carpet tiles moderately lightweight.

ましい。 The glass fiber layer 6 serves to keep the dimensions, that is, the thickness, of the polyvinyl chloride foam layer 5 uniform as a whole during molding, and both woven and nonwoven fabrics can be used, but particularly inexpensive and dimensionally stable ones can be used. It is preferable to use a nonwoven fabric with a weight of 30 to 100 g/m 2 which has excellent properties.

形をなくする上で顕著な効果を発揮する。 Furthermore, according to experiments, the polyvinyl chloride non-foamed layer 7 contains 300 to 500 parts by weight per 100 parts by weight of polyvinyl chloride.
0.5 to 1.5 parts by weight of inorganic filler
It is preferable to form it to a thickness of mm. The purpose of this is to improve dimensional stability and reduce costs; if it is less than 300 parts, the effect of dimensional stability will not be sufficient, and if it is more than 500 parts, the viscosity of the paste sol will become too high, making coating difficult. Because it does. According to the above blending ratio, the non-foamed layer 7
In particular, it increases the strength of carpet tiles, and
This exhibits a remarkable effect in eliminating plastic deformation of the polyvinyl chloride foam layer 5 due to impact loads.

要がある。 Next, an example of the method for manufacturing the tile carpet of the present invention will be explained with reference to FIG. 5a is fed with a metering pump (not shown), compressed air 9 is injected in the middle of feeding, and the OAKS mixer 8 is
This is done by shearing and stirring using fixed blades and rotating blades to disperse air into the sol. Note that when the paste sol 5a is foamed, heat is generated in the oak mixer 8, and if there is excessive heat generation, there is a risk of gelation.
It is necessary to adjust the blend to 5000 cp and to sufficiently cool the mixing head of the Oaks mixer 8 with cold water, preferably with cooling water of 10° C. or lower.

る。 On the other hand, for carpet lining, an endless belt 11 equipped with an oven 10 in the middle and coated with Teflon having mold releasability is prepared, and a non-foaming paste sol 7a is first applied to the surface of the endless belt 11 using a doctor knife 12. A glass fiber cloth 6 is fed out and laminated thereon, and the above-mentioned foamed sol is supplied from an oak mixer 8 onto the glass fiber layer 6, and coated with a doctor knife 13 to a predetermined thickness. Then, after supplying and placing the carpet fabric as the upper surface layer A on top of the carpet, it is pressed with a press roller 14, and then heated in an oven 10 to gel the non-foamed sol 7a and the foamed sol 5a, respectively. After melting, it is cooled and solidified. As a result, the tile carpet shown in FIG. 1 was obtained.

みを防止することが肝要である。 It should be noted that when coating the foamed sol, it is easy to insert secondary air, and this air expands when heated, creating cavities, resulting in convex portions on the product surface. Therefore, the viscosity of the foaming sol should be adjusted to below 20,000 cps (BM type 4, 6 rpm) and the foaming ratio should be selected, and the doctor knife 13 should be shaped to provide a large shearing force to the sol. , it is important to prevent the introduction of secondary air.
