Definitions

  • the present invention relates to a loose-lay floor tile which has on the back face a nonskid backing material using a polyvinyl chloride-based raw material (“polyvinyl chloride” will be referred to as “PVC”, hereinafter).
  • PVC polyvinyl chloride
  • the strength is one-third or smaller of a PVC-based mechanically foamed material described later when the expansion rate is the same.
  • the present invention has an object of providing a loose-lay floor tile which has on the back face a nonskid backing material prepared by using a PVC-based raw material in place of an acrylic mechanically foamed material.
  • the present invention provides:
  • FIG. 1 shows a sectional view of a loose-lay floor tile which has a nonskid backing material on the back face of the floor tile as stripes.
  • the backing material must be a flexible elastomer.
  • Examples of the above material include elastomers having an elongation of 300% or greater.
  • a foamed material is preferable to a non-foamed material from the standpoint of the flexibility.
  • Examples of the above material include foamed materials based on acrylic materials, urethanes and PVC.
  • a material having a suitable tackiness must be selected since separation of sheets of the material having excessively great tackiness becomes difficult when the sheets are packaged and stored for a long time in the condition such that adhesive faces of the sheets are faced to each other although the greater the tackiness of the material, the greater the adhesive effect.
  • Examples of the above material include adhesive coating materials curable with ultraviolet ray and conventional products coated with adhesives.
  • a PVC paste is foamed mechanically, and the foamed paste is solidified and used.
  • foam stabilizers, thixotropy agents, stabilizers, fillers and flame retardants are added, where necessary, in combination with the resin and the plasticizer which are the main components of the paste.
  • the polyvinyl chloride resin as the main component of the PVC paste may be a polymer comprising the vinyl chloride unit alone, it is preferable that a copolymer of vinyl chloride and vinyl acetate or a mixture of PVC and polyvinyl acetate is used since curing can be conducted at a low temperature and the productivity is improved.
  • the content of vinyl acetate in the copolymer is about 3 to 10% by mole and more preferably about 5 to 8% by mole as the monomer unit.
  • a commercial material containing vinyl acetate in the above range may be used.
  • the content of polyvinyl acetate is about 1.5 to 5% by weight and more preferably about 2 to 3% by weight.
  • the content of polyvinyl acetate is smaller than about 1.5% by weight, workability is insufficient, and there is the possibility that the desired strength is not obtained.
  • the content of polyvinyl acetate exceeds about 5% by weight, heat stability during working decreases.
  • the plasticizer is used in an amount of about 50 to 200 parts by weight and preferably about 80 to 120 parts by weight per 100 parts by weight of the resin.
  • the amount of the plasticizer is less than about 50 parts by weight, flexibility of the obtained material is insufficient, and there is the possibility that an excellent foamed material is not obtained.
  • the amount of the plasticizer exceeds about 200 parts by weight, the obtained material is excessively flexible, and there is the possibility that strength of the backing material is small.
  • phthalic ester-based plasticizers such as di-2-ethylhexyl phthalate (DOP) and diisononyl phthalate (DINP) are preferable, and DOP is more preferable for the PVC-based mechanically foamed material.
  • the foaming stabilizer is used when the material is mechanically foamed. It is preferable that a silicone-based surfactant of the hydrophobic type is used as the foaming stabilizer so that the water-repelling property is also exhibited and penetration of water into the foamed material is prevented. It is preferable that the foaming stabilizer is used in an amount of 5% by weight or less. However, it is necessary that at least 3% by weight of the foaming stabilizer be used when the expansion rate of the foamed material is 3 or greater.
  • the expansion rate is about 1.5 to 4 and preferably about 2.5 to 3.
  • the expansion rate exceeds about 4, the material shows marked shrinking during curing by heating, and there is the possibility that workability in coating decreases during application of the foamed sol at a speed of coating of 10 m/minute or greater (the sol does not extend smoothly due to the great expansion rate, i.e., due to a great viscosity).
  • the expansion rate is smaller than about 1.5, there is the possibility that the sufficient nonskid property is not exhibited.
  • the foamed material is preferable to a non-foamed material due to the more excellent nonskid property.
  • Foamed PVC includes the mechanically foamed material described above and chemically foamed materials which are obtained by chemical foaming.
  • the PVC-based mechanically foamed material is preferable since the chemically foamed materials have the following drawbacks (i) to (iv):
  • a high temperature of 200° C. or higher is necessary for the chemical foaming, and the floor tile itself is damaged by the high temperature.
  • the thixotropy agent is used when the plasticizer is used in a great amount or for improving the coating property of the material and preventing flow and deformation of the material applied to the back face.
  • examples of the thixotropy agent include modified urea solutions.
  • the filler and the flame retardant conventional stabilizers, fillers and flame retardants can be used.
  • a nonskid backing material in accordance with the present invention was prepared by mixing the following components, followed by mechanically foaming the resultant mixture (the expansion rate: 2.8).
  • “part” means “part by weight”.
  • a paste of a PVC resin 80 parts (a copolymer containing 7% of vinyl acetate; the number-average molecular weight: 1,700)
  • a PVC resin for blending 20 parts (a copolymer containing 5% of vinyl acetate; the number-average molecular weight: 1,100)
  • a plasticizer (DOP) 120 parts Calcium carbonate treated with fatty 10 parts acids on the surface
  • a silicone-based foam stabilizer 7 parts A modified urea-based thixotropy agent 0.2 parts
  • FIG. 1 On the back face of one loose-lay floor tile which had a size of a 50 cm square and a thickness of 5 mm and made of a plastic, stripes were formed with 50 g of the nonskid backing material prepared above.
  • the floor tile having the backing material was heated by an infra-heater at 165° C. for 5 seconds to solidify the backing material.
  • the sectional view of the obtained floor tile is shown in FIG. 1 .
  • the height of the stripe of the nonskid backing material was 0.3 to 0.5 mm, and the width of the stripe on the face of the floor tile was about 2 mm.
  • the distance between the stripes of the nonskid backing material was about 3 mm.
  • a nonskid backing material was prepared by adding 2 parts by weight of a crosslinking agent “CR-5L” manufactured by E-TEC Co., Ltd. to 100 parts by weight of a nonskid backing material which was a mechanically foamed material prepared by using a commercial acrylic emulsion [manufactured by E-TEC Co., Ltd.; ACRYL EMULSION “A-412A”].
  • the C. S. R. value was measured in accordance with the same method as that used in Example 1 using the obtained floor tile having the backing material. The results of the measurement are shown in Table 1.
  • Example 1 and Comparative Example 1 were each mechanically foamed, applied each to a glass plate of a 500 mm square and solidified by heating in a drying oven at 165° C. for 5 minutes, and sheets of the mechanically foamed materials having a thickness of about 1 mm were prepared.
  • the obtained foamed sheets were separated from the glass plates, and test pieces necessary for the following evaluations were cut out from the sheets. Using the obtained test pieces, properties of the nonskid backing materials were evaluated.
  • a test piece having a size of 40 mm ⁇ 100 mm was dipped into warm water at 46° C., and the water absorption was measured after 1 minute, 1 hour and 24 hours.
  • the PVC-based mechanically foamed material in accordance with the present invention absorbed almost no water.
  • the mechanically foamed material of Comparative Example 1 prepared by using an acrylic emulsion rapidly absorbed water immediately after being dipped into water, and the water absorption reached 172% after 1 minute.
  • a test piece prepared by cutting out into the shape of the No. 3 dumbbell defined in Japanese Industrial Standard K-6301 was dipped into a 2% aqueous solution of sodium hydroxide.
  • the tensile strength and the elongation at break were measured after one week and two weeks in accordance with the method of Japanese Industrial Standard A-6008 at a temperature of 20° C. and a speed of extension of 200 mm/minute. The results are shown in Table 1.
  • the nonskid backing material in accordance with the present invention prepared by using the PVC-based raw material exhibited smaller water absorption, more excellent resistance to alkali and greater strength of the foamed material than those of conventional mechanically foamed materials prepared by using an acrylic emulsion, the same coefficient of slipping resistance (the C. S. R. value) as that of the conventional mechanically foamed materials and excellent properties as the backing material for floor tiles used by simply laying on a floor.
  • Example 1 1 hour 24 hours initial 1 week 2 weeks strength, N/mm 2 Example 1 0.75 0.9 2.5 18.8 0.35 0.57 0.45 0.35 (130) (140) (140) Comparative 0.75 172 186 200 0.13 0 0 0.13 Example 1 (250) (80) (0) Note Control 0.51 — — — — — — — Note: The test piece was swollen to a volume twice as much as the initial volume.
  • the nonskid backing material exhibiting more excellent water-repelling property, resistance to alkali and resistance to moisture, water and alkaline water from the ground coat than those of mechanically foamed materials containing an acrylic emulsion as the main component can be provided.
  • the backing material which provides a foamed material exhibiting a great strength and can bear ordinary dynamic loads can be provided.
