Abstract

PURPOSE:To obtain a resin molded article having soft luster, absorptivity, nonelectrification and enriched with water resistance, durability, fungus resistance or the like by mixing at a specific percent by weight animal bristle powders into a synthetic resin material. CONSTITUTION:Animal bristle powders is mixed at 10-80% by weight into a synthetic resin material, and then made into pellets. The bristle powders are rod-shaped ones microscopically in its granular configurations, and as dispersed into the resin, they interwine with one another like as net meshes and the resin is stretched around the net meshes like rods, as a result, the resin layer becomes hard to be discontinuous and even the mixed rate of the bristle powders is made much, the rate of frailty is less. Namely, when a molded article is manufactured by the use of pellets in which animal bristle powders are mixed with synthetic resin, the bristle powders may not be condensed and distributed in the molded article in a state of being dispersed uniformly. The molded article manufactured with the pellets has excellent solidity, soft feelings and senses, calm color tone and becomes excellent in its electrostatic resistance, moisture permeability or the like.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a resin molded product that has a soft gloss, moisture permeability, water absorption, and non-static properties, and is highly water resistant, durable, and antibacterial. This relates to pellets for forming products.

(Conventional Techniques i, iI) In the case of molded products using only synthetic 11H material, the gloss is not deep and the functionality, that is, hygroscopicity is low, resulting in frequent troughs due to excessive static electricity. ing.

In order to compensate for this drawback, various materials are used as fillers for resin. In addition, in response to the recent trend toward luxury, molded products with static electricity resistance, moisture permeability, water absorption, etc., are required, and have a soft luster and a calm color tone. Attempts have been made to mix leather powder into synthetic resin, and molding pellets have been made for this purpose.

(Unexamined Japanese Patent Publication No. 63-11311) <Problems to be Solved by the Invention> However, conventional molding pellets are still insufficient in terms of color tone, moisture permeability, water absorption, non-static properties, antibacterial properties, and durability. It wasn't.

(Means for Solving the Problems) The characteristic means of the present invention is to mix 10 to 80% by weight of animal hair powder into a synthetic resin material and form it into a pellet.The effect is as follows. It is.

(Function) For example, resin pellets mixed with leather powder have a calm color tone, and have good static resistance, moisture permeability, and water absorption.
If you try to mix in leather powder until it develops characteristics such as Jilt, you will have to increase the amount to achieve it, but if you increase the amount of leather powder mixed in, there is a problem that the strength of the resin will weaken.
As a result, the strength of the molded product decreases and its commercial value decreases. Therefore, there was naturally a limit to increasing the amount of leather powder mixed in. The particle shape of hair powder is microscopically rod-shaped, and when dispersed in resin, they intertwine like a net, and the resin is spread like a film around the mesh, making the resin layer discontinuous. Therefore, even if the amount of hair powder mixed in is increased, the percentage of brittleness is small. In other words, when a molded product is made using a beret made of animal hair powder mixed with synthetic resin according to the present invention,
The hair powder is distributed in a uniformly dispersed state throughout the molded product without agglomeration. Therefore, molded products manufactured using this pellet have excellent fastness, a soft feel, and a calm color tone, and are also excellent in static electricity resistance, moisture permeability, water absorption, etc. Furthermore, the feel, color tone, static resistance, moisture permeability, water absorption, etc. can be freely changed by changing the mixing ratio of hair powder. In other words, the greater the amount of hair mixed in, the stronger the characteristics of the hair will appear, making it more flexible, warmer to the touch, and deeper in color.Furthermore, it has non-static properties, moisture permeability, water absorption, It also gets better.

(Effects of the Invention) As described above, according to the present invention, the gloss has a softer and calmer color tone compared to conventional products, and the moisture permeability, water absorption, and non-static properties are biased, and the product has water resistance, durability, A pellet for producing resin molded products with high bacterial resistance is obtained. Moreover, by using a beret obtained by arbitrarily adjusting the proportion of powdered wool, it is highly flexible, has a warm feel, and has excellent cooling properties.
In addition, it is possible to provide a high-quality molded product that has moisture permeability, water absorption, and non-static properties, and also has excellent properties such as water resistance, durability, and germ resistance.

(Example) Next, examples will be shown.

The carbonized wool (d) was put into a pressure vessel with a heating jacket, and 3 kg/cj of steam was supplied into the vessel and the jacket at the same time. First, the air in the vessel was replaced with steam, and then the vessel was sealed and heated for about 10 minutes. Heated for a minute. After the hair tissue was sufficiently swollen in this manner, the outlet of the pressure vessel was opened all at once to cause swelling due to rapid pressure reduction. This was dried until the moisture content was around 10%, then crushed with an impact crusher and classified to obtain an average particle size of 30μ.
A pellet was made by mixing and kneading 30% of m wool powder and 70% of polyethylene resin mixed with a plasticizer.

The film produced using this pellet in an inflation device has excellent water resistance, durability, and antibacterial properties. It has a different color tone and can be used as a laminate for each building. In the present invention, conventionally used fillers or additives may be added in order to obtain a synthetic resin molded product with further improved physical properties and functions. Further, in order to further characterize the feel of the surface of the molded product, treatments such as sanding to remove a thin layer of resin from the surface are performed as necessary.
