いは中間工程として有している。 These methods each have a step of providing a transparent resin layer as a surface protective layer as a separate step or as an intermediate step.
しかし、これらの方法では以下のような欠点が

のである。 In other words, in method (1), the life of the promotion-inhibiting ink is short and production stability is lacking, in method (2), there are problems with stickiness and toxicity of uncured resin, and in method (3), the life of the curable resin ink is poor. The lack of drying properties significantly impedes production speed. Furthermore, method (4) requires a large amount of heat, and method (5) makes it impossible to achieve sharp embossing. Methods 6 and 7 can provide flooring materials that are simpler and cheaper than the above methods, but in method (7), the transparent resin layer provided in the subsequent process reduces the unevenness effect of the raised ink. However, in any case, a step of previously providing a resin layer on the base sheet is required. The present inventor focused on the advantage of method (6), and used an impregnable base sheet,
A method has been developed in which the step of providing the first resin layer is omitted by providing the transparent resin layer as the top layer.

As shown in the first diagram, first, a pattern part 2a is formed by foaming ink using a foamable resin as a vehicle on a heat-resistant and impregnable base sheet 1, and a pattern part 2b is formed by printing ink using a non-foaming resin layer as a vehicle. will be established. The heat-resistant and impregnated base sheet 1 is a base sheet that is impregnated with the transparent vinyl chloride sol 3 that will be applied later, and that has appropriate air permeability and smoothness in consideration of the transferability of printing ink. .

シートを巻取れる利点もある。 Paper, glass nonwoven fabric, polyester nonwoven fabric, etc. can be used as the base sheet, but considering printability and dimensional stability during processing, 30 to 100 sheets containing asbestos or glass fiber at 5 to 50% can be used.
g/m 2 mixed paper is preferred. Also, polyester nonwoven fabric lacks dimensional stability, but if you use a pattern that does not cause problems even if it has some expansion and contraction, it will weigh 40 to 100 g/
m2 is preferred. Furthermore, when using these impregnating base sheets, compared to using non-impregnating base sheets, there is an advantage that the printed base sheet can be rolled up with a small amount of drying due to the diffusion of the solvent in the foamed ink. There is also.

る。 As the foamed ink constituting the pattern 2a, a low-temperature foaming ink using microspheres or a high-temperature foaming ink containing a foaming agent in a resin sol can be used, but the latter is preferable considering the application and processing method. The resin constituting the foamed ink is preferably a polyvinyl chloride resin, its derivatives, or a mixture or copolymer with other resins, in view of its adhesion to the vinyl chloride sol applied later. As blowing agents, hydrazides such as benzenesulfonyl hydrazide; azos such as azodicarbonamide; nitrosos such as dinitrosopentatetramine; or inorganic blowing agents such as sodium bicarbonate are used. 3 to 10 parts per 100 parts of resin (based on weight, same below)
If necessary, add 0 to 50 parts of a plasticizer such as dioctyl phthalate (DOP) or dibutyl phthalate (DBP), a foaming aid, a coloring agent such as titanium white, a stabilizer, a filler, etc. A slow-drying solvent such as xylene or turbene is added to the foamable resin to create a viscosity suitable for printing. The suitable viscosity for printing is 2,000 to 3,000 cps, but foamed ink made by adding xylene causes the resin sol in the ink to thicken over time, and foamed ink made by adding turbene lacks drying properties, so adjust the amount accordingly. do. Silk screen printing is the most desirable printing method for applying foam ink, considering the amount of ink to be applied.
It is also possible to use a gravure method with a plate depth of about 80 to 150 μm. In some cases, a flexographic method, a letterpress method, an offset method, etc. can also be used.

も可能である。 The ink constituting the non-foaming pattern 2b is preferably a polyvinyl chloride resin based in consideration of its adhesion to the transparent vinyl chloride sol, similar to the foaming ink, but it is important to consider impregnability and use a resin with low film-forming properties. be. To reduce film-forming properties, it is also possible to lower the degree of polymerization of the vehicle resin or to add extender pigments such as calcium carbonate, precipitated barium, and clay.
50 to 500 g/m 2 of transparent PVC sol 3 is applied to the surface of such a printed base sheet, but the wear resistance and
Considering workability, 100 to 200 g/m 2 is most desirable. As a coating method, in addition to known coating methods such as knife coating, flow coating, curtain coating, and bar coating, printing coating using a silk screen solid plate is also possible.

製造法は印刷工程と塗布加熱工程の２工程により
なる簡易な製造法である。 The base sheet coated with transparent PVC sol may not be rolled up as it is, but the transparent PVC sol may be turned into a semi-gel in a heating furnace and rolled up, and a separate foaming process may be performed, but considering the simplicity of the process, it is recommended to It is preferable to gel the transparent vinyl chloride sol at the same time as foaming the foaming ink. These conditions depend on the properties of the blowing agent and resin, but are preferably 150°C to 250°C and 1 minute to 3 minutes. Regarding the timing of heating, in order to prevent delamination of the base sheet when it is commercialized, it is preferable to gel the transparent PVC sol at the same time as it reaches the back side of the base sheet, which maintains fluidity and is impregnable. . In order to obtain this fluidity, the plasticity and the amount of solvent in the transparent PVC sol are adjusted. By gelling the sol at the same time as heating and foaming, a floor material as shown in the second figure in which the foamed ink 2a becomes foamed 2a' can be obtained. The manufacturing method of such flooring material is a simple manufacturing method consisting of two steps: a printing step and a coating and heating step.

できる。 The flooring material manufactured in this way can be used as is by being attached to or placed on a building base material, but as shown in the third figure, adhesive is applied to the plywood 5 which has been subjected to actual processing A and B. It can also be used as a plywood flooring material by laminating it through 4. The flooring material of the present invention is particularly suitable for use as a plywood flooring material due to cost, specifications, etc. If used as a plywood flooring material, it can be bonded to plywood using an adhesive 4 containing a concealing pigment such as titanium white, without providing the solid layer with concealing properties as described above. The solid printing step described above can be omitted.
