Definitions
- the present inventors have conducted deliberate studies on a laminate having excellent contact strength with a polyolefin-based polymer and being useful as a skin material of a molded article.
- a layer of the vinyl chloride resin (first layer) a layer of the composition containing the vinyl chloride resin and the olefin polymer (third layer), a layer between the first layer and the third layer,
- the present inventors have found that they have excellent adhesiveness with the present invention, and have completed the present invention.
- the dynamic frames are, for example, an thermoplastic thermoplastic resin and ethylene. This can be carried out by kneading the composition comprising -olefin copolymer and the dilating agent using a single-screw extruder or a twin-screw extruder.
- the shear rate during dynamic suspension is preferably 1 ⁇ 10 3 sec_1 or more.
- step ⁇ may be performed after completion of step i, or may be performed overlapping step i.
- Step 1 can be performed by incorporating.
- the molding surface of the mold for powder molding functions as a part of the molding surface of one mold of the molding apparatus. According to this method, it is possible to obtain a molded body in which the pattern on the surface of the skin material formed during the production of the skin material is well maintained.
- Table 1 shows the evaluation results of the molded body.
- Table 1 shows the evaluation results of the molded body.
- a three-layer skin material was obtained in the same manner as in Example 1 except that the powder obtained in Reference Example 10 was used instead of the powder obtained in Reference Example 3.
- a 3-layer skin material was obtained in the same manner as in Example 9 except that the powder obtained in Reference Example 15 was used instead of the powder obtained in Reference Example 8.
- a molded product was obtained in the same manner as in Example 2 except that the skin material obtained in Example 23 was used instead of the skin material obtained in Example 1.
- a molded product was obtained in the same manner as in Example 9, except that the powder obtained in Example 25 was used instead of the skin material obtained in Example 1.
- the fixed container 1 and the mold 2 were rotated three times over 20 seconds using the uniaxial rotating device S. By this operation, the powder is supplied onto the resin layer (2), and a part of the powder is fused to each other to form the resin layer (3) on the resin (2), and the powder is not fused. The crumbly powder was collected in Vessel 1. Thereafter, the container 1 was removed from the mold 2.
- This molded product had a clear grainy surface on its surface.
- the Shore A hardness was 54 and the cushioning property was good.
- the peel strength between the skin material and the base material was 1470 g / 20 ram, and the adhesive strength between the skin material and the base material was good.
