Problems solved by technology

However, in the above countermeasures, the texture of the skin material may be impaired, or the flexibility and bendability of the skin material may be reduced.
Therefore, in the above countermeasures, the obtained skin material is difficult to be used as an interior material such as an automobile seat and a molded body having complicated unevenness.

Embodiment 1

[0209] As the resin contained in the composition for forming a vinyl chloride resin skin layer, polyvinyl chloride (Dayang Vinyl Chloride Co., Ltd.: TH-2800) having an average degree of polymerization of 2,800 was used.

[0210] (Composition for forming skin layer)

[0211]

[0212] (Composition for forming foamed resin layer)

[0213] · Polyvinyl chloride resin Taiyang Vinyl Chloride Co., Ltd.: TH-1300:

[0214]

[0215] Using a calendering apparatus, each of the compositions described above was used to form a laminate in which the skin layer and the composition layer for forming a foamed resin layer were laminated. The thickness of the skin layer in the laminate was 250 μm, and the thickness of the foamed resin layer-forming composition layer (before foaming) was 500 μm.

[0216] Apply about 15 g / m to the surface of the composition for forming a foamed resin layer of the obtained laminate 2 Adhesive (polyurethane-based emulsion adhesive) to bond the base fabric.

...

Embodiment 2

[0225] In the same manner as in Example 1, except that the content of the silicone / acrylic copolymer used in Example 1 was replaced by the amount (10 parts by mass) described in Table 1 with respect to 100 parts by mass of vinyl chloride resin with a degree of polymerization of 2800 The skin material of Example 2 was obtained.

Embodiment 3

[0227] In addition to using a vinyl chloride resin with a degree of polymerization of 1700 (Dayang Vinyl Chloride Co., Ltd.: TH-1700) instead of the vinyl chloride resin with a degree of polymerization of 2800 used in Example 1, and replacing the content of the silicone / acrylic copolymer with Table 1 Except for the amount (10 parts by mass) described in , the skin material of Example 3 was obtained in the same manner as in Example 1.

Abstract

The present invention provides: a synthetic resin skin material that has a base fabric and a vinyl chloride resin skin layer that is formed on the base fabric, the vinyl chloride resin skin layer including a vinyl chloride resin that has a degree of polymerization of 1600-3000 and a silicone / acrylic copolymer that is included in an amount of 3-20 parts by mass relative to 100 parts by mass of thevinyl chloride resin; and a method for producing the synthetic resin skin material.

Description

technical field [0001] The invention relates to a synthetic resin skin material and a manufacturing method thereof. Background technique [0002] In recent years, in automotive interior parts (instrument panels, door trims, seats, ceilings, etc.), railway vehicles and aircraft interior parts (panels, seats, ceilings, etc.), furniture, boots-shoes-bags , Construction interior and exterior parts, clothing surface materials and linings, wall materials, etc., use synthetic resin skin materials with excellent durability instead of natural leather or fiber sheets. The synthetic resin skin material has a natural leather-like concavo-convex, that is, grain (grain) pattern on the outermost surface, and the grain pattern characterizes the appearance. [0003] For example, with regard to automotive interior parts, it is important to impart a sense of luxury to the skin materials for interiors as vehicles become more sophisticated. [0004] image 3 It is a schematic cross-sectional v...
