- the production of the multilayer molded body by the powder slush molding method is performed according to the method of obtaining the two-layer molded body. That is, for example, from a non-foamed skin layer, a foamed layer and a protective layer After forming a crosslinked foaming powder melting layer on the skin layer, the multilayer molded body thus formed is supplied with a thermoplastic resin or a thermoplastic resin composition powder on this surface, and the powders are thermally fused to each other. After obtaining a sheet-like molten material on the molding surface, the excess powder that has not been heat-sealed is removed, and then cross-linked in a heating furnace (temperature is usually 160 to 260 ° C, time is 15 seconds to 5 minutes). After foaming, it is obtained by removing it from the caro heating furnace, cooling the mold, and removing it from the mold.
- a heating furnace temperature is usually 160 to 260 ° C, time is 15 seconds to 5 minutes.
- the crosslinked foaming powder composition of the present invention has excellent storage stability of an uncrosslinked product, so that crosslinking does not proceed during storage, and comprises a non-foamed skin layer and a foamed layer by a powder slush molding method.
- the foam has low compression set, excellent surface skin, and little skin ding, etc.
- ⁇ ia from the skin layer is smooth and excellent, and it is possible to maintain a good feel.
- a foam having sufficient performance can be obtained even under low-temperature, short-time crosslinking foaming conditions, it is possible to reduce costs and improve productivity. Therefore, it can be widely used for various cushioning materials for automobiles, architecture, general industry, etc., specifically for instrument panels, headrests, consoles, armrests, door trims, etc. of automobiles.
- the peroxides used in Examples and Comparative Examples were all products diluted to 40% by weight. For example, in the case of adding 6 parts by weight in the table, it becomes 2.4 parts by weight (6 parts by weight X 0.4) when converted to a pure product.
- ODTMA-C 1 Octadecyl trimethyl ammonium chloride
- TAI C-M60 Nippon Kasei Co., Ltd.
- Triallyl isocyanurate Noguard 445 Uniroyal Byeon: Antiaging agent
- Sumilizer-I TPS Anti-aging agent manufactured by Sumitomo Chemical Co., Ltd.
- CellMike S Oxybenzenesulfonyl hydrazide, a blowing agent manufactured by Sankyo Kasei Co., Ltd.
- Cell Mic C 121 foaming agent azodicarbonamide manufactured by Sankyo Chemical Co., Ltd. Examples and comparative examples were performed as follows.
- the compounds shown in Tables 1 to 3 were put into a Toyo Seiki Lapoplast mill (volume: 100 ml), and kneaded under the conditions of a temperature of 105 ° C, a rotation speed of 50 rpm, a kneading time of 5 minutes, and a charge rate of 80%. Was done.
- the resin powder for the skin layer was supplied on the mold in a heap, and after being left for 15 seconds, the excess The powder was removed and kept for 30 seconds.
- the crosslinked foaming powder obtained above was supplied onto the sheet-like molten material, and after leaving it for 20 seconds, excess crosslinked foaming powder that was not heat-sealed was removed.
- Crosslinking and foaming were performed for 2 minutes in a gear-oven C.
- the mold taken out of the gear oven was cooled with water to obtain a two-layer molded body composed of a non-foamed skin layer and a foamed layer.
- the evaluation of the obtained foam molded article was performed as follows.
- the skin layer of the two-layer molded product was peeled off with a force cutter knife, and only the foam layer was used as a sample.
- the density before and after foaming was measured, and the density was determined by the following equation.
- Each honey degree was measured by an automatic densitometer (Denssimter) manufactured by Toyo Seiki Seisaku-sho.
- the state of the surface skin on the foam side of the two-layered molded product obtained by the powder slush molding was visually judged to be superior or inferior.
- the unevenness of the surface skin was remarkable, it was judged impossible to use because the unevenness was transferred to the skin side when the reinforcing layer was bonded.
- the following four levels were used for evaluation.
- a foam layer of a two-layer molded body obtained by the powder slush molding, and a black skin layer Is determined as a measure of the degree of adhesion at the interface of the skin. If large air bubbles are generated at the interface, the skin layer becomes extremely thin, and the adhesion at the interface becomes poor. In addition, if the skin layer is partially thinned, the design becomes poor and it is not practically used. Therefore, the interface is preferably a micro-foamed layer. According to the method, when the foam layer is directed toward a fluorescent lamp and viewed from the black skin side, if there is a skin skin, the thin portion of the skin looks bright, so that the degree of adhesion at the interface can be determined. The following four levels were used for evaluation.
- the foam is compressed using a hand press under the following conditions, and the permanent deformation is measured.
- Compression set (%) 1 0 0-(LL Q ) 1 0 0
- the powder for cross-linking and foaming was placed in a constant temperature bath at 23 ° C, 40 ° C, or 55 ° C, and the change in moldability over time was examined. The next day after the preparation of the cross-linked foaming powder, the slash-molded one was used as a sample, and the surface skin of the foamed layer was compared with the surface skin of the foamed layer molded using the heat-treated cross-linked foaming powder. If the crosslinking is prematurely performed during storage and storage stability is poor, the fluidity is poor and the surface skin of the foam layer is inferior.
- a scale loupe (10 times) was applied to the cut section of the foam to measure the cell size.
- Comparative Example 1 which is outside the scope of the present invention, uses a peroxide having a temperature of 10 ° C. or less to obtain a half-life of 10 hours. Poor sex etc.
- Comparative Examples 2 to 6 the compression set of the foam was large because of the use of the ammonium conjugates other than the quaternary ammonium salt, and the skin peel appeared.
