Problems solved by technology
In addition, if the higher fatty acid amide coated on the surface is exposed to high temperature, it is easy to melt and peel off, etc.
In addition, the surface active agent applied on the surface will be washed away if it comes into contact with moisture or water after application and drying, and the effect will not last.
[0008] In addition, if a large amount of higher fatty acid amide is added to the resin composition constituting the PP foam molding, the same effect as the above (1) can be expected. However, due to the addition of a large amount of higher fatty acid amide, as mentioned above, if PP foams Molded products are used as automotive interior parts, for example. Higher fatty acid amide vaporizes under high humidity and high temperature in the interior of the car. It is speculated that the window glass will cause fog or odor.
[0009] In addition, in the method described in the above (3), on the surface of the foamed plastic product, fine unevenness composed of protrusions formed to minimize the noise generated by friction is provided, but in terms of preventing the frictional sound of the foamed moldings , the effect is still very low

[0053] [raw materials of the small particle]
[0054] A propylene-ethylene random copolymer was used as the propylene resin (A). The melt flow rate (MFR) of this copolymer was 8 g / 10 minutes. In addition, MFR is a value measured based on test condition 14 (230 degreeC / 2.16kgf load) of JISK7210 (1976). In addition, the melting point of this copolymer was 143.5°C.
[0055] A first composition composed of organic acid-modified olefin-based elastomer (B), fatty acid amide (C), and ethylene-(meth)acrylate copolymer (D) was used. As the elastomer (B), methyl methacrylate, methacrylic acid, and acrylic acid were graft-polymerized on ethylene-octene copolymer rubber with a melting point of 59° C. Graft polymer of butyl ester (B-1). The graft polymer (B-1) is graft polymerized by ethylene-octene copolymer rubber, methyl methacrylate, methacrylic acid and butyl acrylate in a weight ratio of 90:4:2:4.
[0056] Sinapic acid amide with a melting point of 81° C. was used as the fatty a...

Abstract
The invention relates to a bubbling particle composed of polypropylene resin compound, at the volume density of 10g / L-450g / L, wherein the polypropylene resin compound contains at least 50mass% of propone resin (A), olefin elastomer (B) and fatty acid amide (C) modified by organic acid. The invention relates to a bubbling shaped body prepared from the bubbling particles, while the bubbling shaped body has a little friction voice when being abraded.
Description
technical field [0001] The present invention relates to expanded particles and a foamed molded article produced therefrom, and in detail, relates to a foamed molded article with reduced frictional noise generated when rubbed. Background technique [0002] The expanded molded article composed of the polypropylene resin composition can be produced by an in-mold molding method using expanded beads obtained by expanding the polypropylene resin composition (hereinafter referred to as PP expanded beads). This in-mold molding method can produce foamed moldings with a wide range of expansion ratios from low expansion ratios to high expansion ratios, and can also produce foamed moldings from simple shapes to complex shapes. method is very useful. [0003] However, it is known that in a foamed molded article composed of PP expanded particles (hereinafter referred to as a PP foamed molded article), the PP foamed molded articles are brought into contact with each other and rubbed again...
