Embodiment 1 and 2

[0122] As a blooming / bleeding inhibitor, 0.007 Al having a half-width of about 0.8 degrees of a diffraction peak at 31.7 degrees in an X-ray diffraction pattern is used 2 o 3 ·ZnO·0.15H 2 O powder (specific surface area: 104m 2 / g, median diameter: 1.7 μm), and a raw material composition in which the total content of the blooming / bleeding inhibitor is 3% by mass or 6% by mass relative to the total polymer component is prepared. Then, a test for confirming the effect of suppressing the blooming / bleeding phenomenon was performed (see Table 1).

Embodiment 3

[0124] As a blooming / bleeding inhibitor, ZnO 0.27H with no clear diffraction peak detected in the X-ray diffraction pattern was used 2 O powder (specific surface area: 188m 2 / g, median diameter: 9.8 μm), and a raw material composition in which the total content of the blooming / bleeding inhibitor was 3% by mass relative to the total polymer component was prepared. Then, a test for confirming the effect of suppressing the blooming / bleeding phenomenon was performed (see Table 1).

Embodiment 4

[0126] As a blooming / bleeding inhibitor, use 0.13Na which does not detect a clear diffraction peak in the X-ray diffraction pattern 2 O·Al 2 o 3 8.2SiO2 2 0.7H 2 O powder (specific surface area: 245m 2 / g, median diameter: 7.9 μm), and a raw material composition in which the total content of the blooming / bleeding inhibitor was 3% by mass relative to the total polymer component was prepared. Then, a test for confirming the effect of suppressing the blooming / bleeding phenomenon was performed (see Table 1).

Abstract

The blooming / bleeding inhibitor of the present invention is characterized by comprising a powder containing an amorphous inorganic material. The aforementioned amorphous inorganic material is preferably a compound represented by the following general formula (1): aM 1 2 O·bM 2 O·cM 3 2 o 3 ·dM 4 o 2 · eP 2 o 5 · fH 2 O(1) (where, M 1 is an alkali metal atom, M 2 is a divalent metal atom, M 3 is a trivalent metal atom, M 4 is a tetravalent metal atom, at least one of a, b, c, d and e is a positive number, the rest are 0 or a positive number, and f is a positive number).

Description

technical field [0001] The present invention relates to suppressing blooming or blooming of compounding ingredients from a molded article obtained from a raw material composition containing rubber, elastomer, etc. (hereinafter referred to as "elastomer molded article") / Exudation Inhibitor. Background technique [0002] Conventionally, in addition to rubber, elastomer, etc., various additives may be blended in raw material compositions for forming elastomer molded articles according to required performance. For example, in the case of rubber, it can be mixed with processing oil, processing aids, anti-aging agents, vulcanization accelerators, etc., and in the case of elastomers, it can be mixed with antioxidants, light stabilizers, plasticizers, etc. agent etc. [0003] In recent years, although various properties of elastomer molded products have been improved, it is sometimes found that additives appear (exposed) over time. This blooming / bleeding phenomenon not only det...
