定した。その結果を第２表に示す。[Industrial Application Field] The present invention relates to a vinyl chloride resin sheet for vacuum forming.
In particular, the present invention relates to a vinyl chloride resin sheet for vacuum forming, which exhibits less shrinkage after vacuum forming. [Prior art] Conventionally, as a polyvinyl chloride resin sheet for vacuum forming,
Sheets using vinyl chloride resin plastisol have been used to make molded products softer. In order to form a sheet with a squeeze pattern using a vinyl chloride resin plastisol, a vinyl chloride resin plastisol composition is applied to a release paper having an uneven pattern, and this is gelled and peeled off from the release paper. The uneven pattern of the release paper is clearly transferred to the resulting vinyl chloride resin sheet, and the unevenness of the aperture, even minute ones, can be sufficiently expressed, making it suitable for interior materials for vehicles such as automobiles. [Problems to be solved by the invention] As mentioned above, sheets formed from vinyl chloride resin plastisol have a soft feel even when vacuum formed, and are suitable for interior materials for automobiles, etc., but they are not conventionally used. PVC resin plastisols for vacuum forming have an average degree of polymerization of 1,400 or more, and those with an average polymerization degree of about 2,000 have often been used. This has the problem of large shrinkage of the sheet after vacuum forming, especially when the vacuum formed product is inserted into another molded product for interior parts of automobiles, etc., or set in a separate mold and polyurethane is applied. In the case of injection molding, there is a major problem in that secondary shrinkage of the vacuum-formed product makes it difficult to insert it into the injection mold. The present invention was made against the background of such conventional technology, and provides a vinyl chloride resin sheet for vacuum forming that exhibits extremely little secondary shrinkage after vacuum forming. (Means for Solving the Problems) That is, the present invention provides: (1) A vacuum forming product comprising one or more vinyl chloride resin layers made of a vinyl chloride resin plastisol composition formed on the surface of a PVC/ABS resin sheet. Vinyl chloride resin laminated sheet. (2) A vinyl chloride resin film layer made of a vinyl chloride resin plastisol composition is formed on the surface of the PVC/ABS resin sheet, and a thermoplastic synthetic resin skin layer is formed on the film layer. (3) A vinyl chloride resin sheet for vacuum forming according to claim 2, wherein the film layer is a non-foamed layer. (4) The film layer is a foamed layer. The vinyl chloride resin sheet for vacuum forming according to claim 2. (5) The thermoplastic synthetic resin forming the skin layer is formed from polyurethane or a vinyl chloride resin plastisol composition. A vinyl chloride resin sheet for vacuum forming.The vinyl chloride resin used in the present invention includes vinyl chloride alone, or vinyl chloride and other vinyl monomers such as vinyl acetate, ethylene, propylene, Examples include polymers or copolymers obtained by emulsion polymerization or microsuspension polymerization with maleate esters, methyl methacrylates, methyl methacrylates, acrylic esters, higher vinyl ethers, etc., but these may be used alone. However, a plurality of them may be used in combination. Examples of liquid plasticizers that can be used to form plastisol from vinyl chloride resin include di-2-ethylhexyl phthalate (DOP) and diisononyl phthalate. (DINP), butyl hensyl phthalate (BBP), diisodecyl phthalate (DI
DP), general phthalate ester plasticizers such as diundecyl phthalate (DUP), dioctyl adipate (DOA), dioctyl sebacate (DO3), and dioctyl azelaate (DOZ). Trioctyl trimellitate (TOT) is a common fatty acid ester plasticizer.
In addition to trimellitic acid ester plasticizers represented by M), triaryl phosphate plasticizers represented by tricresyl phosphate (TCP), tricylyl phosphate (TXP), etc., epoxidized soybean oil General plasticizers such as epoxy plasticizers such as epoxy plasticizers, polymer plasticizers such as polyester plasticizers such as polypropylene adipate, and chlorinated paraffin can be used, but these plasticizers alone cannot be used. They may be used, or two or more types may be used in combination. These plasticizers can be used for various purposes,
An appropriate amount is added to the vinyl chloride resin. Generally, the amount added is about 30 to 100 parts by weight per 100 parts by weight of the vinyl chloride resin, but the present invention is not limited to this. As the PvC resin used to form the PVC/ABS resin sheet used in the present invention, all the vinyl chloride resin compositions that form the vinyl chloride resin layer described above can be used. However, the vinyl chloride resin is suspension polymerized. Acrylonitrile-butadiene-styrene copolymer is generally used as ABS resin, but
Copolymers that use other acrylic monomers instead of acrylonitrile, such as methyl methacrylate-butadiene-styrene copolymers, copolymers that use acrylic rubber instead of butadiene, and copolymers that use other acrylic monomers instead of butadiene. Copolymers using diene monomers, copolymers using other styrene monomers instead of styrene, etc. can be used, and are not limited to ordinary ABS copolymers. PVC/ABS resin sheet is made of vinyl chloride resin and A
Blend with BS resin, add additives such as plasticizers and stabilizers that are generally used as additives for vinyl chloride resin as necessary, and process the vinyl chloride resin by calendering etc. Obtained by sheeting using a sheet forming method. Note that NBR and acrylic processing aids can also be added as additives. In addition, the vinyl chloride resin of the present invention includes, as a stabilizer,
For example, metal soaps such as lead stearate, barium stearate, zinc stearate, cadmium stearate, calcium stearate, tin stabilizers such as dibutyltin dilaurate, diptyltin malate, organotin mercaptide, organotin sulfonamide, tribasic Lead sulfate, tribasic lead phosphite, tribasic lead maleate, etc. are used, and these stabilizers can be used alone or in combination of two or more, and there are no particular restrictions on the stabilizers. The amount of the stabilizer added is about 0.5 to 10 parts by weight, preferably about 1 to 5 parts by weight, per 100 parts by weight of the vinyl chloride resin. A foamed sheet can also be obtained by adding a foaming agent to this vinyl chloride resin. In the case of foaming, foaming can be carried out by using, for example, azodicarbonamide, dinitrosopentatetramine, oxybisbenzene hydrazide, etc., which are foaming agents for vinyl chloride resins, and if necessary, a foaming accelerator or Foam suppressants may also be added. Furthermore, a foamed sheet can also be obtained by mechanically foaming the vinyl chloride resin plastisol for obtaining the vinyl chloride resin sheet for vacuum forming of the present invention. In this case, it is preferable to use an organic surfactant such as sodium alkylhenzenesulfonate or potassium alkylhenzenesulfonate or a silicone oil such as polydimethylsiloxane or polymethylphenylsiloxane as the foam stabilizer. The amount of foam stabilizer added is 1 part vinyl chloride resin plastisol
The amount is 0.1 to 5 parts by weight per 00 parts by weight. In addition to the above, flame retardants such as antimony dioxide and trialkoxyalkyl phosphate, fillers such as calcium carbonate, talc, hydrotalcite, magnesium carbonate, and aluminum hydroxide, processing aids, and pigments may be added as necessary. , ultraviolet absorbers, antistatic agents, antiaging agents, etc. can also be added. In the present invention, it is sufficient that the surface of the PVC/ABS resin sheet has at least one vinyl chloride resin layer made of a plastisol composition of vinyl chloride resin, and this vinyl chloride resin layer is a single layer. There may be one or multiple layers. In the case of multiple layers, a vinyl chloride resin layer with a low average degree of polymerization and a vinyl chloride resin layer with a high average degree of polymerization may be used in combination. In this case, the vinyl chloride resin layer with a low average degree of polymerization A skin layer may be formed by being exposed on the front side, or a film layer may be formed by being exposed on the back side.
When the skin layer is formed of a vinyl chloride resin layer with a high average degree of polymerization, one or more layers of a vinyl chloride resin sheet obtained from a plastisol composition of a vinyl chloride resin with a low average degree of polymerization are formed. It may also be a polyvinyl chloride resin sheet for vacuum forming with a multilayer structure. In this case, the coating layer may be a non-foamed layer, a foamed layer, or a combination of a foamed layer and a non-foamed layer. It is preferable that the skin layer is formed from a plastisol composition of a vinyl chloride resin having a high average degree of polymerization, as the vacuum molded product obtained by vacuum forming has very little fading and curvature change on the surface. [Function] In the present invention, the polyvinyl chloride resin sheet for vacuum forming has at least IN a vinyl chloride resin layer made of a vinyl chloride resin plastisol composition on the surface of the PVC/ABS resin sheet. Unlike sheets made of a vinyl chloride resin layer formed from a plastisol composition whose main component is vinyl resin, there is no secondary shrinkage after vacuum forming, and it is used for vehicles such as automobiles, ships, etc. Suitable for inner panels, safety bands, lids, console boxes, assist grips, etc. used in vehicle interiors. [Examples] Examples of the present invention will be specifically described below, but the present invention is not limited to these Examples. Example 1 After kneading the vinyl chloride resin plastisol of Formulation Example 1 shown in Table 1 for 20 minutes in a Raikai machine, it was applied to a release paper having a leather-like uneven pattern to a thickness of 0.5 mm.
The mixture was gelled by heating at 00'C for 2 minutes to obtain a vinyl chloride resin sheet. The obtained vinyl chloride resin sheet clearly had the uneven pattern formed on the release paper transferred thereto, and had a good leather-like appearance. This vinyl chloride resin sheet was laminated to a PVC/ABS resin sheet prepared by kneading the following composition at 185°C and calendering the mixture to a thickness of 0.6 mm to obtain a vinyl chloride resin laminate sheet for vacuum forming. . This vacuum-forming vinyl chloride resin laminated sheet was heated with a far-infrared heater to a surface temperature of 160°C.
When the product was vacuum formed, a good vacuum formed product was obtained. The shrinkage rate (secondary shrinkage rate) of the obtained vacuum-formed product was measured. The results are shown in Table 2.

The smaller this shrinkage rate is, the more preferable it is. Example 2 A vinyl chloride resin laminate sheet for vacuum forming was obtained in the same manner as in Example 1 using the vinyl chloride resin plastisol of Formulation Example 2. The same tests as in Example 1 were conducted on this vacuum-forming vinyl chloride resin laminate sheet. The results are shown in Table 2. Examples 3 to 5 Using the vinyl chloride resin plastisol of Formulation Example 1.2.3.4, combinations of Formulation Example 1 and Formulation Example 3, Formulation Example 4 and Formulation Example 2, and Formulation Example 4 and Formulation Example 3 were used. The surface layer on the release paper is 0.
Example except that two layers are applied, in which the film is applied to a thickness of 1 mm, gelled, and then coated on the epidermis layer to a thickness of 0.4 mm, and then gelled. 1
A vinyl chloride resin laminate sheet for vacuum forming was obtained in the same manner as above. The same tests as in Example 1 were conducted on this vacuum-forming vinyl chloride resin laminate sheet. The results are explained in the second section.
Shown in the table. Comparative Examples 1 to 2 Using the vinyl chloride resin plastisol of Formulation Example 1.2.3.4, a combination of Formulation Example 4, Formulation Example 3, Formulation Example 1, and Formulation Example 2 resulted in no surface layer on the release paper. Apply the coating to a thickness of .11 mm, gel it, and form an epidermis layer on the surface layer of 0.4 mm.
The mixture was coated to a thickness of 1.0 mm, and gelled to obtain a two-layer vacuum-forming vinyl chloride resin laminate sheet. The same tests as in Example 1 were conducted on this vacuum-forming vinyl chloride resin laminate sheet. The results are shown in Table 2. (Left below) Table 2 As is clear from Table 2, the vinyl chloride resin laminate sheet for vacuum forming of the present invention has a chlorinated polyvinyl chloride resin laminate made of a plastisol composition of vinyl chloride resin on the surface of the PVC/ABS resin sheet. Since it has at least one vinyl resin layer, it can be seen that secondary shrinkage after vacuum forming is extremely small. The vacuum forming vinyl chloride resin laminate sheet (Comparative Example 2) having a layer made of a vinyl chloride resin plastisol composition with a low average degree of polymerization is a vacuum forming sheet made only of a vinyl chloride resin plastisol composition having a high average degree of polymerization. The vinyl chloride resin laminate sheet for vacuum forming of the present invention (Examples 1 to 5) has less secondary shrinkage and is better than the vinyl chloride resin laminate sheet for vacuum forming (Examples 1 to 5). This is preferable because secondary shrinkage is small. [Effects of the Invention] As described above, the present invention provides a polyvinyl chloride resin sheet for vacuum forming with a small vinyl chloride resin layer made of a vinyl chloride resin plastisol composition on the surface of the PVC/ABS resin sheet. Since it has one layer, it does not undergo secondary shrinkage after vacuum forming, unlike a sheet made of only a vinyl chloride resin layer formed from a plastisol composition whose main component is vinyl chloride resin.
Vacuum-formed products can be obtained that are soft and have an excellent texture, and are suitable for inner panels, safety pads, lids, console boxes, assist grips, etc. used in the interior of vehicles such as automobiles and vehicles such as ships. . 7 ■b Procedural amendment Heisei April 16th 1, Indication of the case 1990 Patent Application No. 6688 2, Title of the invention PVC resin laminated sheet for vacuum forming 3, Person making the amendment Relationship to the case Application Person Address: 22-5 Daikyomachi, Shinjuku-ku, Tokyo Telephone: 03 (2)
