| titleOfInvention | Method for producing polyolefin foam |
| abstract | (57) [Abstract] [Purpose] A polyolefin foam which is excellent in moldability of two-stage foaming and reduces physical property difference between inner and outer layers by a simple method of simply applying a crosslinking inhibitor on the inner wall surface of a primary mold. A manufacturing method is provided. [Structure] A crosslinking inhibitor (2, 2 ') is provided around four corners a to d of the inner wall surface of the primary mold (410 x 410 x 40 mm). -Methylene-bis-4-methyl-6-t-butylphenol). Then, the primary mold is filled with a mixture of a polyolefin (polyethylene, etc.), a cross-linking agent and a foaming agent, and heated (160 ° C., 30 minutes) under pressure to decompose a part of the foaming agent. Then, an intermediate foam is manufactured. Then, the intermediate foam is processed into a secondary mold (100 having an internal shape corresponding to the shape and size of the final foam product). Put in 0x1000x100mm) and heat (165 ° C, After 30 minutes), the rest of the foaming agent is decomposed under normal pressure to produce a final foam. |
