Embodiment 1～17 and comparative example 1

[0127] A bright fluororubber mixture containing iodine-containing fluororubber (VDF / TFE / HFP copolymer) capable of peroxide crosslinking was prepared according to the formula described in Table 1 using a rubber roller. The obtained mixture was press-molded at 170° C. for 6 minutes into a sheet having a thickness of 1 mm, a length of 100 mm, and a width of 100 mm. Furthermore, as secondary vulcanization, it heated at 180 degreeC for 2 hours in an oven. The specular surface of the sheet was measured. In addition, the molded sheets obtained in Examples 2 and 9 were evaluated for taste, and the results are shown in Table 2.

reference example 1

[0129] 3 parts by mass of MAGNAPEARL 1000 (manufactured by BASF Color & Effects) was added to 100 parts by mass of a silicone rubber compound (SH841U, manufactured by Dow Corning Toray) to prepare a rubber mixture. The obtained mixture was molded into a sheet having a thickness of 1 mm, a length of 100 mm, and a width of 100 mm, and subjected to secondary vulcanization to obtain a silicone rubber molded sheet. Table 2 shows the evaluation results of flavor property.

reference example 2

[0131] A silicone rubber molding sheet was obtained in the same manner as in Reference Example 1, except that 3 parts by mass of Lumina Royal Copper 9390H (manufactured by BASF Color & Effects) was added to 100 parts by mass of the silicone rubber compound (SH841U, manufactured by Dow Corning Toray). Table 2 shows the evaluation results of flavor property.

Abstract

Provided is a fluororubber molded article having a glittering property and a low flavoring property. The fluororubber molded article is characterized by having a glittering property and containing a fluororubber.

Description

technical field [0001] The present invention relates to fluororubber molded articles. Background technique [0002] As a technique for imparting gloss to rubber products, a method of providing a metallic luster film layer on the surface of the rubber product is known. [0003] For example, Patent Document 1 describes a silicone rubber product with metallic luster, which is formed on the surface of the base material in sequence with a primer layer, a porous metallic luster film layer, and a middle coat layer and / or a top coat layer. A product with metallic luster, characterized in that the above-mentioned substrate is made of silicone rubber, the above-mentioned primer layer is made of resin with at least elasticity, and the above-mentioned middle coat and / or top coat is made of at least light-transmitting and elastic resin. resin, and between the surface of the substrate made of silicone rubber and the primer layer, there is an adhesion improving treatment layer of the prim...
