Description

[Technical field]

[0001] The present invention relates to a cosmetic material and a method for producing a cosmetic material. [Background technology]

[0002] Wallpaper, which is widely used as an interior material for houses, etc., is composed of resin material, paper (cellulose), and calcium carbonate powder. Among these, wallpaper that uses polyvinyl chloride resin as the resin material (hereinafter sometimes referred to as PVC wallpaper) is a sheet material in which a paper layer and a polyvinyl chloride layer are bonded together, and contains calcium carbonate powder to prevent discoloration.

[0003] Among such PVC wallpapers, wallpaper waste generated during the renovation and demolition of houses, etc., and wallpaper scraps generated during the manufacture and processing of PVC wallpapers are difficult to separate into the paper layer and the vinyl chloride layer, so they have traditionally been disposed of together in landfills or incinerated. However, from the perspective of environmental conservation, it is being considered to use recovered PVC wallpapers as recycled raw materials.

[0004] Examples of products manufactured using recycled cloth waste without separating it include packing materials such as tile carpets and flooring. This packing material has poor surface properties and cannot be used as a surface material, so it has been used as a backing material that is not used on visible surfaces (see, for example, Patent Document 1).

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A decorative material and a method for manufacturing a decorative material according to one embodiment of the present invention will be described below with reference to the drawings. It should be noted that each of the embodiments described below is specifically described to provide a better understanding of the gist of the invention, and unless otherwise specified, does not limit the present invention to a specific scope.

[0011] [Cosmetic materials] The decorative material according to one embodiment of the present invention includes a waste cloth material made of PVC wallpaper and a polyvinyl chloride resin. The surface of the decorative material according to one embodiment of the present invention has an arithmetic mean roughness (Sa) of 15 μm to 60 μm, a maximum height (Sz) of 150 μm to 600 μm, and a gloss of 10 or less.

[0012] Fig. 1 is a perspective view showing a decorative material according to one embodiment of the present invention. Fig. 2 is a cross-sectional view along the thickness direction of the decorative material according to one embodiment of the present invention. Fig. 3 is a cross-sectional view along the thickness direction of the decorative material showing a joint structure of the decorative material according to one embodiment of the present invention. As shown in Fig. 1, the decorative material 1 of this embodiment has a plate shape with one long side in a plan view. The decorative material 1 of this embodiment has a plurality of protrusions 2 extending in the short side direction (width direction) or the long side direction (length direction). The protrusions 2 are continuously arranged in parallel in the length direction or width direction of the decorative material 1.

[0013] As shown in Fig. 2, in the decorative material 1, the surface on which the protrusions 2 exist is referred to as the front surface (upper surface in Fig. 2) 1a, and the flat surface on which the protrusions 2 do not exist is referred to as the back surface (lower surface in Fig. 2) 1b. The front surface 1a of the decorative material 1 is also the front surface 2a of the protrusions 2. Therefore, the protrusions 2 form a crescent shape that rises from the back surface 1b side of the decorative material 1 toward the front surface 1a side of the decorative material 1.

[0014] As shown in Figures 2 and 3, the decorative material 1 has two joint ends 1A, 1B that face each other along the short side or long side. One joint end 1A has a male tongue 3. The other joint end 1B has a female tongue 4. As shown in Figure 3, when joining two decorative materials 1, the male tongue 3 of one decorative material 1 is inserted into the female tongue 4 of the other decorative material 1. This makes it possible to join the two decorative materials 1 together without making the seam noticeable.

[0015] In the decorative material 1 of this embodiment, the arithmetic mean roughness (Sa) of the surface 1a is 15 μm or more and 60 μm or less, preferably 20 μm or more and 55 μm or less, and more preferably 25 μm or more and 50 μm or less. If the arithmetic mean roughness (Sa) is less than the lower limit, the desired surface property with an inorganic texture cannot be obtained. If the arithmetic mean roughness (Sa) is more than the upper limit, the desired surface property with an inorganic texture cannot be obtained.

[0016] The arithmetic mean roughness (Sa) of the surface 1a of the decorative material 1 can be measured based on the international standard "ISO 25178".

[0017] In the decorative material 1 of this embodiment, the maximum height (Sz) on its surface 1a is 150 μm or more and 600 μm or less, preferably 230 μm or more and 550 μm or less, and more preferably 245 μm or more and 500 μm or less. If the maximum height (Sz) is less than the lower limit, the desired surface property with an inorganic texture cannot be obtained. If the maximum height (Sz) is more than the upper limit, the desired surface property with an inorganic texture cannot be obtained.

[0018] The maximum height (Sz) of the surface 1a of the decorative material 1 can be measured based on the international standard "ISO 25178".

[0019] In the decorative material 1 of the present embodiment, the gloss level on the surface 1a is preferably no greater than 10, more preferably no greater than 8, and even more preferably no greater than 7. When the gloss level is equal to or less than the upper limit, the desired surface texture with an inorganic feel can be obtained.

[0020] The glossiness of the surface 1a of the decorative material 1 can be measured using a gloss checker "IG-320" manufactured by Horiba, Ltd. (both the incident angle and the receiving angle are 60°).

[0021] Examples of PVC wallpaper constituting the wallpaper waste include wallpaper waste generated during house renovation and demolition, and wallpaper scraps such as cut pieces generated by cutting new PVC wallpaper to size. In this embodiment, recycled PVC wallpaper is used.

[0022] PVC wallpaper, which is a component of wallpaper waste, is composed of, for example, a paper layer as a base material and a vinyl chloride layer covering it, and the ratio of the paper layer to the entire PVC wallpaper is generally 20% to 30% by mass. The vinyl chloride layer is composed of vinyl chloride resin and its filler, calcium carbonate, plasticizer, etc.

[0023] More specifically, the PVC wallpaper that makes up the wallpaper waste should contain, taken as 100% by mass, 25% to 45% by mass of polyvinyl chloride resin, 15% to 35% by mass of paper, 10% to 50% by mass of calcium carbonate, and 10% to 30% by mass of plasticizer.

[0024] The polyvinyl chloride resin may be either a recycled resin obtained by recovering discarded polyvinyl chloride resin or a newly produced virgin resin. For example, a polyvinyl chloride resin obtained by separating waste cloth can be used as the recycled resin.

[0025] The polyvinyl chloride resin may contain at least a soft polyvinyl chloride resin (S-PVC) and may further contain a hard polyvinyl chloride resin (R-PVC). The polyvinyl chloride resin may contain at least a hard polyvinyl chloride resin (R-PVC) and may further contain a soft polyvinyl chloride resin (S-PVC).

[0026] The mixing ratio of the waste cloth to the polyvinyl chloride resin is preferably 20 parts by mass:80 parts by mass to 50 parts by mass:50 parts by mass, and more preferably 20 parts by mass:80 parts by mass to 40 parts by mass:60 parts by mass. In the above mixing ratio, if the ratio of the waste cloth is lower than 20 parts by mass:80 parts by mass, the amount of PVC wallpaper that can be recycled is reduced, and the recycling efficiency of PVC wallpaper is reduced. In addition, in the above mixing ratio, if the ratio of the waste cloth is higher than 50 parts by mass:50 parts by mass, there is a concern that the molded resin extrusion molding may not have a practical strength.

[0027] The decorative material 1 of this embodiment preferably has a bending strength of 30 MPa to 90 MPa, more preferably 40 MPa to 85 MPa, and even more preferably 50 MPa to 80 MPa. When the bending strength is equal to or greater than the lower limit, the material is less likely to bend during application and is therefore easier to apply.

[0028] The bending strength of the decorative material 1 can be measured in accordance with JIS K 7171-1994 (Test method for bending properties).

[0029] The decorative material 1 of this embodiment has a Charpy impact value of 1.5 kJ / m 2 More than 4.5kJ / m 2 Less than 2.0 kJ / m is preferable. 2 More than 4.0kJ / m 2 Less than 3.0 kJ / m is more preferable. 2 More than 3.8kJ / m 2 When the Charpy impact value is equal to or greater than the lower limit, the material is less likely to break when hit by an object.

[0030] The Charpy impact value of the decorative material 1 can be measured in accordance with Annex 4 (Regulations) of JIS K 7111-1-2012 (Plastics - Test method for Charpy impact strength).

[0031] The decorative material 1 of this embodiment is preferably an extrusion-molded material or an injection-molded material. An extrusion-molded material is produced by an extrusion molding machine. An injection-molded material is produced by an injection molding machine.

[0032] According to the decorative material 1 of this embodiment, the surface has an arithmetic mean roughness (Sa) of 15 μm or more and 60 μm or less, a maximum height (Sz) of 150 μm or more and 600 μm or less, and a gloss level of 10 or less, so that a decorative material with an inorganic texture and design can be provided.

[0033] [Manufacturing method of decorative materials] A manufacturing method for decorative material according to one embodiment of the present invention is a manufacturing method for decorative material according to the above-mentioned embodiment, and includes a recycled raw material formation process in which the crushed waste cloth is mixed with a particulate first resin material to form a recycled raw material, a water absorption adjustment process in which the recycled raw material is adjusted so that its water absorption is in the range of 0.01% by mass or more and 1.0% by mass or less, a recycled molding material formation process in which the recycled raw material is mixed with a second resin material to form a recycled molding material, a molding process in which the recycled molding material is molded by extrusion molding to form a precursor decorative material, and a cooling sizing process in which the precursor decorative material is cooled.

[0034] FIG. 4 is a flow chart showing the steps of a method for producing a decorative material according to one embodiment of the present invention.

[0035] To manufacture the decorative material of the above embodiment, first, recycled PVC wallpaper (waste wallpaper) is crushed to a size that can be mixed uniformly with the polyvinyl chloride resin (resin material) to be mixed (crushing step S1). The size of the crushed waste wallpaper may be, for example, about 2 mm to 20 mm, preferably about 3 mm to 8 mm. A general crusher (crusher, cutter) capable of crushing sheet materials can be used to crush the waste wallpaper.

[0036] The PVC wallpaper that makes up the wallpaper waste should contain, taken as 100% by mass, 25% to 45% by mass of polyvinyl chloride resin, 15% to 35% by mass of paper, 10% to 50% by mass of calcium carbonate, and 10% to 30% by mass of plasticizer.

[0037] Next, a particulate first resin material containing polyvinyl chloride resin is mixed with the crushed PVC wallpaper (scrap cloth) to form a recycled raw material (recycled raw material formation step S2). The polyvinyl chloride resin used as the first resin material to be mixed with the PVC wallpaper (scrap cloth) may be particulate with a particle diameter of, for example, about 1 mm to 20 mm. The polyvinyl chloride resin (first resin material) to be mixed may be either recycled resin or virgin resin. When using recycled resin, it is preferable to select one that is as close to colorless as possible in order to widen the range of coloring possible in the subsequent process.

[0038] Moreover, the polyvinyl chloride resin used as the first resin material contains at least a soft polyvinyl chloride resin (S-PVC), and may further be mixed with a hard polyvinyl chloride resin (R-PVC).

[0039] In the recycled raw material formation step S2, the mixing ratio of the waste cloth material and the first resin material constituting the recycled raw material may be, for example, in a mass ratio range of 3:7 to 9:1, and the mixing ratio is preferably in a range of 5:5 to 7:3.

[0040] Next, the recycled raw material, which is a mixture of PVC wallpaper (waste cloth) and polyvinyl chloride resin (first resin material), is heated to a temperature equal to or higher than the melting temperature of the recycled raw material using a melting granulator or the like, and pelletized (granulation step S3). Note that this granulation step S3 may not be necessary depending on the shape of the recycled raw material obtained in the recycled raw material formation step S2.

[0041] Next, a second resin material containing polyvinyl chloride resin is mixed with the pellet-shaped recycled raw material formed in the granulation step S3 to form a recycled molding material (recycled molding material formation step S4). The polyvinyl chloride resin as the second resin material to be mixed with the recycled raw material may be, for example, particulate with a particle diameter of about 1 mm to 20 mm. The polyvinyl chloride resin (second resin material) to be mixed may be either recycled resin or virgin resin. When using recycled resin, it is preferable to select one that is as close to colorless as possible in order to widen the range of coloring possible in the subsequent process.

[0042] Moreover, the polyvinyl chloride resin used as the second resin material contains at least a rigid polyvinyl chloride resin (R-PVC), and may further contain a flexible polyvinyl chloride resin (S-PVC) mixed therein.

[0043] In the recycled molding material formation step S4, the mixing ratio of the recycled raw material and the second resin material may be in the range of 30 mass% to 65 mass%:70 mass% to 35 mass%, preferably in the range of 35 mass% to 50 mass%:50 mass% to 65 mass%.

[0044] The ratio (mixing ratio) of the waste cloth material contained in the recycled molding material thus obtained to the total of the first resin material and the second resin material is preferably 20 parts by mass:80 parts by mass to 50 parts by mass:50 parts by mass, more preferably 20 parts by mass:80 parts by mass to 40 parts by mass:60 parts by mass. If the ratio of the waste cloth material is lower than 20 parts by mass:80 parts by mass, the amount of PVC wallpaper that can be recycled will be low, and the recycling efficiency of PVC wallpaper will decrease. Also, if the ratio of the waste cloth material is higher than 50 parts by mass:50 parts by mass, there is a concern that the molded resin extrusion molding will not be able to obtain a practical strength.

[0045] The recycled molding material obtained in the recycled molding material formation step S4 may be pelletized by heating the recycled molding material to a temperature equal to or higher than its melting temperature using a melting granulator or the like.

[0046] Next, the recycled molding material obtained in the recycled molding material formation step S4 is molded by extrusion molding to mold a precursor decorative material of any shape (molding step S5). When molding using the recycled molding material, an extrusion molding machine equipped with a die modeled after the shape of the precursor decorative material is used. For example, the pellet-shaped recycled molding material is introduced into a cylinder heated to a melting temperature or higher, and the molten recycled raw material is extruded toward the die by a screw to obtain a precursor decorative material.

[0047] Next, the precursor decorative material obtained in the forming step S5 is cooled in a sizing mold to form a decorative material of any desired shape (cooling and sizing step S6).

[0048] In the method for producing a decorative material according to the present embodiment, the time from the completion of the molding step S5 to the start of the cooling sizing step S6 is preferably 3 seconds or more. The time is the time from when the precursor decorative material is discharged from the die of the extrusion molding machine to when it enters the sizing die. Between the completion of the molding step S5 and the cooling sizing step S6, the precursor decorative material is allowed to cool. By setting the time for this cooling to 3 seconds or more, the arithmetic mean roughness (Sa), maximum height (Sz) and glossiness of the surface of the final decorative material are within a predetermined range, and the desired surface property with an inorganic texture is obtained. Note that, the longer the time from when the precursor decorative material discharged from the die enters the sizing die, the rougher the surface of the final decorative material becomes, and the less glossy the surface of the decorative material becomes. In addition, when the surface of the decorative material has an uneven shape, there is a difference in the cooling speed between the vicinity of the convexities and the vicinity of the concaves. Due to the appropriate difference, the surface of the decorative material becomes rough and the gloss of the surface of the decorative material decreases.

[0049] According to the manufacturing method for the decorative material of this embodiment, the time from the completion of the molding process to the start of the cooling sizing process is 3 seconds or more, so that the arithmetic mean roughness (Sa), maximum height (Sz) and gloss on the surface of the decorative material are within the specified ranges, and the desired inorganic texture surface is obtained.
