(Industrial Application Field) The present invention relates to deodorizing polyvinyl chloride (hereinafter referred to as PVC).
The present invention relates to sheet materials, and more specifically to deodorizing PVC sheet materials useful as wall covering materials and various surface materials. (Prior Art) Conventionally, PVC sheet materials are made by applying PVC paste resin to the surface of paper, woven fabric, metal, etc., gelling it, and then surface-processing it as necessary.
It is widely used as wall covering material or surface material of various articles under the names of wallpaper and leather. Also, foamed PVC sheet materials made of PVC paste resin containing a foaming agent are also widely used. (Problems to be Solved by the Invention) PVC sheet materials such as those described above are widely used as wall covering materials, floor materials, exterior materials for houses, interior materials for automobiles, etc. In such places, it is desirable to absorb the bad odors generated or accumulated. For example, by using PVC sheet material that can absorb bad odors in toilets, cars, etc.
You can expect to keep those areas free of odors at all times. (Means for Solving the Problems) As a result of intensive research to solve the problems of the prior art as described above, the present inventor discovered that when manufacturing PVC sheet materials using PVC paste resin, PVC
The present invention was completed based on the finding that a deodorizing PVC sheet material with excellent deodorizing properties can be obtained by incorporating a specific deodorizing component into paste resin. That is, the present invention applies a PVC paste resin containing a deodorizing component onto a base material, then gels it,
Deodorizing PVC with further surface treatment as necessary
The sheet material is a deodorizing PVC sheet material characterized in that the above-mentioned deodorizing components are ferrous salt, citric acid and/or citrate. Next, to explain the present invention in more detail, the PVC paste resin used in the present invention is one in which PVC particles prepared by suspension polymerization are suspended in a suitable liquid plasticizer, and does not contain a solvent. It contains both a plastisol and an organosol containing a small amount of solvent. Other necessary components such as stabilizers, fillers, gelling agents, foaming agents, and coloring agents are optionally included. Such PVC paste resin itself has been widely used in the past, and various grades are available on the market, any of which can be used in the present invention. The main feature of the present invention is that the above-mentioned ferrous sulfate and citric acid and/or citrate are used in combination as a deodorizing component. That is, it is known in the prior art to use an aqueous solution of ferrous salt as a deodorizing agent. When the ferrous salt is impregnated and dried by heating, the ferrous salt precipitates as water evaporates, making it easy for the precipitated ferrous salt to fall off the sheet. The deodorizing effect was reduced, and the commercial value of sheets, especially sheets with various types of printing, was significantly lowered. In the present invention, when such ferrous salt is combined with citric acid or citrate or both and added to PVC paste sol to create sheets, the ferrous salt does not impair the deodorizing effect. It was also discovered that the ferrous salt causes less brown discoloration, and together with the deodorizing effect of citric acid and/or citrate, it exerts a deodorizing effect that is greater than the sum of the unique deodorizing effects of each compound. be. The individual deodorizing compounds used in the present invention are all known compounds, and various ferrous salts can be used as the ferrous salt, but ferrous sulfate is particularly preferred. As the citrate, an alkali metal salt of citric acid, particularly a sodium salt, is suitable. As for the deodorizing component made of ferrous salt and citric acid and/or citrate as described above, their usage ratio is also important.If the total amount is 100 parts by weight, 80 parts by weight of ferrous salt. The ratio of citric acid and/or citrate is 20 to 10 parts by weight to ~90 parts by weight, and the most preferable combination and ratio is 80 to 90 parts by weight of ferrous salt and 15 to 5 parts by weight of citric acid. part, and 5 to 1 part by weight of citrate, and in such a combination and ratio, the above objects of the present invention are best achieved. Any of the above-mentioned deodorizing components can be used in the present invention, and the amount thereof used is preferably 0.1 to 20% by weight in the PVC paste resin. If the amount used is less than 0.1% by weight, the deodorizing effect will be insufficient, and if the amount used exceeds 20% by weight, the effect will not increase any further, which is uneconomical. The deodorizing PVC sheet material of the present invention uses a PVC paste resin containing the above-mentioned deodorizing component, and can be applied to any base material such as paper, woven fabric, non-woven fabric, metal, wood, etc. Approximately on the surface of
Apply to a thickness of approximately 0.05 to 2.0 mm and heat at approximately 140 to 230℃.
It is obtained by gelation by heating at a temperature of about 0.5 to 2 minutes. In addition, in the above, by incorporating an appropriate foaming agent into the PVC paste resin in advance,
A foamed deodorizing PVC sheet material can be obtained. Furthermore, it is natural that the surface of the deodorizing PVC sheet material of the present invention formed as described above can be subjected to various surface treatments, such as embossing, printing, formation of a surface layer, etc. (Action/Effect) Deodorizing PVC of the present invention obtained as described above
The sheet material contains a relatively large amount of organic polycarboxylic acid, which is a deodorizing component, so it has the property of absorbing basic malodorous components, such as ammonia-based malodorous components, so it eliminates malodors. It is very useful as a surface material for wall coverings, flooring, decorative materials, etc. in places where it occurs or accumulates. Next, the present invention will be explained in more detail with reference to Examples. Note that parts or percentages in the text are based on weight. Example 1 50 parts of PVC paste resin (Sumirit PXN, manufactured by Sumitomo Chemical), 20 parts of dioctyl phthalate, 4 parts of lactic acid ester plasticizer (manufactured by CLP Daihachi Chemical), 1 part of cadmium-barium stabilizer, 20 parts of calcium carbonate , 5 parts of zinc oxide, 80 parts by weight of finely ground ferrous sulfate, 15 parts by weight of citric acid, and 5 parts by weight of sodium citrate were thoroughly mixed to prepare a plastisol. This was applied to the surface of flame-retardant paper to a thickness of 0.2 mm, and gelatinized at 140°C for 60 seconds. Next, the surface thereof was subjected to printing and embossing to obtain the deodorizing PVC sheet material of the present invention. 50mm of the above deodorizing PVC sheet material of the present invention
Cut the pieces into 200mm x 200mm pieces, glue the two pieces back to back to avoid the influence of the back side, put this in a 300ml Erlenmeyer flask, and add 28% ammonia water 10
Micron liters were injected and the tank was sealed to completely gasify the ammonia. When ammonia gas was measured over time using a Kitagawa gas detection tube at 25℃,
The following deodorizing effects were obtained.
