The present invention provides a method for producing durable flooring materials for use under particularly harsh conditions, such as factory floors. Conventionally, the transparent polyvinyl chloride (PVC) layer on the surface of flooring materials has been cross-linked to improve the cigarette flame resistance of flooring materials, protect the surface, and maintain durability. However, conventional cigarette flame-resistant flooring materials provide only a light level of durability suitable for use in stores, etc., and rather, emphasis has been placed on fashionability. However, even harsher heat resistance, such as on factory floors,
In areas where solvent resistance and chemical resistance are required, the crosslinking density of the surface layer must be further increased. Usually, a larger amount of crosslinking agent is added to the PVC paste for this purpose, but this has disadvantages such as loss of thermal stability and discoloration due to heat crosslinking, decolorization due to ultraviolet rays and visible light, and decreased weather resistance. appeared, and whitening due to water absorption was unavoidable due to the inclusion of a crosslinking agent. Such a phenomenon has been a cause of a significant decrease in the commercial value of fashion flooring materials having a transparent surface layer. The object of the present invention is to obtain a durable flooring material with excellent heat resistance, solvent resistance, chemical resistance, etc. without reducing its external commercial value. According to the present invention, the surface layer is heat-crosslinked by blending more crosslinking agents and pigments into the PVC paste than in conventional floor material surface layers, thereby making it possible to hide the color change of the crosslinked resin. The method for crosslinking PVC of the present invention is to
Thermal crosslinking of the paste resulted in crosslinking with the highest density in the shortest time. On the other hand, thermal crosslinking by the calender method has a low crosslinking density, other crosslinking methods such as ultraviolet irradiation are not suitable for opaque cases, and electron beam irradiation requires large-scale equipment investment, all of which are undesirable. . Another object of the present invention is to obtain a flooring material having a crosslinked surface layer and a dimensionally stable base fabric with high efficiency using a simple device. The present invention consists of an opaque high-density heat-crosslinked polyvinyl chloride paste resin surface layer and a non-crosslinked polyvinyl chloride paste resin layer that are color-hidden with a pigment and crosslinked with a crosslinking agent selected from dimercaptothiadiazole and dithiol-S-triazine derivatives. A method for producing a flexible and durable flooring material, characterized in that a laminated sheet consisting of a laminate sheet and a dimensionally stable base fabric are laminated by pressure through an extruded polyvinyl chloride resin layer using the residual heat of the extruded resin layer, The gist is: The present invention will be explained below based on the drawings. FIG. 1 shows the manufacturing method of the present invention. 1 is high-density thermally crosslinked PVC paste resin (hereinafter referred to as high crosslinked resin)
This is a surface layer, and 2 is a PVC paste non-crosslinked resin (hereinafter referred to as non-crosslinked resin) layer. The highly crosslinked resin layer 1 and the non-crosslinked resin layer 2 are firmly adhered to form a laminated sheet 3. Crosslinked PVC paste resin layer 1
30 to 30 parts by weight of plasticizer per 100 parts by weight of PVC paste resin
Add 100 parts by weight, color with pigment, add 0.5 to 5 parts by weight of dimercaptothiadiazole, dithiol-S-triazine derivatives, etc. as a crosslinking agent, and other crosslinking aids such as strong basic amines, heat stabilizers, etc. Mix and heat at 150-250℃ for 2-5 minutes. As will be described later in the Examples, the crosslinked resin layer obtained has a higher crosslinking density than the transparent crosslinked PVC resin conventionally used as the surface layer of flooring materials, as determined by tests such as the swelling method and the cuyulastometer method. cross-link to. The pigment is added to the extent that it colors the PVC paste layer and hides the base. The non-crosslinked resin layer 2 is formed of PVC paste resin, and both the highly crosslinked resin layer 1 and the extruded resin layer 4 described below must have good adhesion.
The non-crosslinked resin layer 2 is obtained by pregelling a non-crosslinked PVC paste onto a release sheet (not shown). The above-mentioned crosslinkable PVC paste solution is applied onto the obtained non-crosslinked resin layer and crosslinked by heating.
In this way, the laminated sheet 3 is obtained. The laminated sheet 3 must have sufficient flexibility. The highly crosslinked resin surface layer 1 of the obtained laminated sheet 3 has high durability in terms of heat resistance and solvent resistance. The cross-linked resin layer 1 is colored with a pigment that has hiding power and is opaque, so it has conventional cigarette flame resistance.
Even if the crosslinking density is increased above the transparent surface layer of PVC crosslinked flooring, no discoloration is observed due to heating, and a desirable appearance as a flooring material is obtained.Also, no whitening is observed even when moisture is attached, and non-crosslinked resin It is not affected by the color of the base of layer 2. The non-crosslinked resin layer 2 firmly adheres the highly crosslinked resin surface layer 1 and the PVC extruded resin layer 4. When the obtained laminated sheet 3 is peeled off from the release sheet and passed through the pressure roll 7, the extruded resin layer 4 extruded from the extruder 5 is pressed against the extruded resin layer 4 by residual heat while the extruded resin layer 4 is not cooled. The extruded resin layer 4 is made by mixing 100 parts by weight of a synthetic resin such as PVC with 200 to 500 parts by weight of a filler such as calcium carbonate, talc, chalk, etc., and extruding it at 160 to 190°C to an arbitrary thickness.
Uniform molding of 0.5 to 3 mm. Also, the dimensionally stable base fabric 6 is pressed almost simultaneously with the laminated sheet 3 by the pressure roll 7' due to residual heat while the extruded resin layer 4 is not cooled. Dimensionally stable base fabrics used in the present invention include glass woven fabrics, glass nonwoven fabrics, glass nets, linen fabrics, polyester fabrics, mixed fabrics of these fabrics, cold sand, and combinations of the above fabrics and thermoplastic resin films such as polyester. A laminate or the like is suitable. FIG. 2 is a sectional view of the flooring material of the present invention. 8,8' is
The PVC paste is a highly crosslinked resin layer, 2 is a non-crosslinked resin layer, 4 is an extruded resin layer, and 6 is a dimensionally stable base fabric. Cross-linked PVC colored with different pigments
Print the paste resin liquid to a constant thickness of 0.3 to 1.5 mm using a screen printing device, etc.
Heat crosslinking is performed at 150-250°C for 2-5 minutes. In addition to a plain flooring material in which patterns 8, 8' of different colors are obtained on the highly crosslinked resin layer, it is also possible to obtain a durable flooring material having a relatively thick patterned layer. It is desirable that the highly crosslinked resin layer of the present invention has a crosslinking density of 50% or more of that of conventional cigarette flame resistant flooring materials. Being colored and opaque hides discoloration caused by heating, and does not whiten due to water absorption as does conventional tobacco fire resistant flooring. Furthermore, the colored crosslinked resin of the present invention has good heat resistance, solvent resistance, and chemical resistance, and exhibits excellent durability. The non-crosslinked portion of the laminated sheet is in close contact with the above-mentioned highly crosslinked resin surface layer, and the non-crosslinked resin layer has good compatibility with the extruded resin layer when the surface layer and extruded resin layer are bonded under heat. Provides strong adhesion between layers. In the extruded layer, the surface layer and the dimensionally stable base fabric are simultaneously bonded by thermocompression bonding, and the flooring material of the present invention can be laminated with high efficiency without the need for any other adhesive or the like. With the extrusion method, it is possible to adjust the desired thickness at once, whereas with the calender method, there is a limit to the thickness that can be obtained. In addition, resin processing using the extrusion method allows a large amount of filler to be added, which not only allows the product to be supplied at a low price, but also increases thermal conductivity, which can contribute to improving the heat resistance of the surface of the flooring material. Regarding the dimensionally stable base fabric, it is important to ensure the safety of the floor surface in places where accidents may occur during daily work such as factory floors, and the use of the stable base fabric in the present invention is important. This eliminates the problems of flooring, blistering, and curling up, increasing the safety of factory floors. With the above-described structure, the present invention can efficiently produce a high-performance, durable flooring material that cannot be obtained by conventional methods of producing flooring materials. Examples are shown below. Example 1 A non-crosslinked PVC paste was applied to a thickness of 0.2 mm on a release sheet, pre-gelled at 120°C, and 60 parts by weight of plasticizer and 2.5-dimercapto were added to 100 parts of PVC.
2 parts by weight of 1,3,4-thiadiazole, 1.8-diazabicyclo(5,4,0)-undecene-7
A PVC paste containing 1 part by weight of an appropriate amount of pigment was applied to a thickness of 0.5 mm, heat-crosslinked at 220°C for 2 minutes, and the resulting laminated sheet was peeled off from the release sheet.
This laminated sheet is mixed with 300 parts by weight of calcium carbonate per 100 parts by weight of PVC, and is kneaded and extruded at 180°C to form a dimensionally stable base fabric between the laminated sheet and a blended fabric of polyester and linen through a 2 mm thick extruded resin layer. were simultaneously crimped with a crimping roll using residual heat to obtain the durable flooring material of the present invention. Table 1 shows a comparison between the crosslinked resin layer of the obtained flooring material and the surface layer of a conventional cigarette-resistant flooring material.

The resulting laminated sheet was pressed onto the extruded resin layer at the same time as the same dimensionally stable base fabric as in Example 1. In Examples 1 and 2, the high crosslink density resulted in superior weather resistance, heat resistance, and solvent resistance compared to conventional tobacco fire-resistant flooring materials, and water absorption and whitening did not occur when rainwater was brought in or cleaned.
