Problems solved by technology

However, even if only a small percentage of brightener is added, sufficient metallic texture and glossy appearance cannot be imparted (for example, a flip value of 3 or more), so that the resin molded body cannot provide high-quality texture with metallic texture and glossy appearance
[0019] Furthermore, any techniques for triaxial orientation control and orientation distribution control are currently unknown

Embodiment 1

[0144] A room temperature curing type liquid silicone rubber having a viscosity of 100 Pa·s was prepared as the resin material of Sample 26. A scaly PC permalloy flake with an average particle size of 24 μm and an aspect ratio of 40 was prepared as the ferromagnetic brightener 10 . Next, the prepared ferromagnetic brightener 10 was added and uniformly dispersed in the prepared sample 26, thereby obtaining a slurry. The addition rate of the ferromagnetic brightener 10 is as low as 10wt%, such as 2wt%. The slurry thus obtained was poured into a non-magnetic glass container 25 (cavity) with a diameter of 20 mm and a thickness of 2 mm, and the container 25 was placed in Figure 8A and Figure 8B On the turntable 20 of the rotating magnetic field apparatus 15 shown in. Experiment in this state.

[0145] Next, at Figure 8A and Figure 8B In the rotating magnetic field apparatus 15 shown in , a rotating magnetic field was applied to the target at a rotational speed of 40 rpm b...

Embodiment 2

[0161] Regarding the three-axis orientation control of ferromagnetic brighteners, using Figure 9A and Figure 9B Experiments were conducted with the rotating magnetic field apparatus 16 shown in , in order to prove that the ab surfaces of all the particles of the ferromagnetic brightener 10 added to the resin material of the sample 26 faced the upper surface of the sample 26 (triaxial orientation control state) . In the rotating magnetic field device 16, the sample 26 is placed in the region between the magnetic poles 17 and 18, which has a uniform magnetic field without a magnetic field gradient. Experiments were conducted using the rotating magnetic field apparatus 16 under the condition that only triaxial orientation control was performed on the permalloy flakes as the ferromagnetic brightener 10 added to the molten resin 11 .

[0162] Scale-like PC permalloy flakes (ferromagnetic brightener 10) with an average particle size of 24 μm and an aspect ratio of 40 were added ...

Embodiment 3

[0165] With regard to the orientation distribution control of the ferromagnetic brightener, a confirmatory experiment on the displacement motion was performed using a PC permalloy flake as the ferromagnetic brightener 10 of Example 1, in order to prove that iron is controlled inside the molten resin 11 of the sample 26. Orientation (arrangement) distribution of the magnetic brightener 10.

[0166] In Example 3, the flaky PC permalloy flakes (ferromagnetic brightener 10) with an average particle size of 24 μm and an aspect ratio of 40 were added and uniformly dispersed into room temperature curing liquid silicone rubber with a viscosity of 100 Pa s ( resin material), thus obtaining a slurry.

[0167] The addition rate of the ferromagnetic brightener 10 is low, for example 2wt%. Furthermore, a room-temperature-curing liquid silicone rubber without additives was placed on the slurry thus obtained. The same experiment as in Example 1 was carried out under this condition.

Abstract

A resin molded body comprising a polymeric material such as one of thermoplastic resin, thermosetting resin, elastomer and rubber added with a desired amount of ferromagnetic brightener having shape anisotropy and a method for producing the same. When the polymer material is in the state of molten resin inside the mold cavity, the polymer material is subjected to three-axis orientation control and orientation distribution control. Orientation of the ferromagnetic brightener in the resin, and displacing the ferromagnetic brightener mixed in the molten resin in a desired direction, by which the ferromagnetic brightener mixed in the molten resin is displaced to the design surface side, The orientation is distributed intensively, and the molding process is carried out by this.

Description

technical field [0001] The present invention relates to a resin material coloring technique using a ferromagnetic brightener or a ferromagnetic bright material added to molten resin, and more particularly, to a resin molded body and a manufacturing method thereof. A resin molded body is formed by applying a desired rotating magnetic field to a shape-anisotropic ferromagnetic brightener added to a molten resin stick. The resin molded body can exhibit a metallic texture and a bright appearance resulting in a high-quality texture, and can suppress defects in the appearance. Background technique [0002] In recent years, in order to reduce volatile organic compounds in terms of environmental measures and to reduce the cost of resin components, colored resin materials are increasingly used for the appearance of resin molded bodies. The colored resin material is not subjected to surface treatment such as coating, and the colored resin material itself is colored for molding in a c...
