Abstract

PROBLEM TO BE SOLVED: To provide brush bristles where different kinds of brush bristle materials mutually adhere each other by using an ultrasonic vibration.SOLUTION: The brush bristles are the bristles where grinding brush bristle materials and polishing brush bristle materials, where abrasive grains with different properties are mixed, adhere each other by forming a welding part by an ultrasonic vibration on mutual contact surfaces. at least one of first abrasive grains are mixed in the grinding brush bristle material, and at least one of second abrasive grains are mixed in the polishing brush bristle material. It is favorable that the brush bristle materials are made of a thermoplastic resin, etc., for example. The brush bristle materials where the two kinds of abrasive grains with different properties are mixed are obtained by generating frictional heat by the ultrasonic vibration on the mutual contact surfaces, so as to form the welding part.

Description

  The present invention relates to a brush hair that bonds different types of brush hair materials to each other using ultrasonic vibration. The brush bristles of the present invention can be bonded in a short time even if they are different types of brush bristle materials, and since no adhesive is used, no foul odor is generated during the operation.

  The brush bristle material described in Japanese Patent Application Laid-Open No. 2008-12125 is a combination of a good portion of both materials by integrating a synthetic resin material and a metal material. Different types of materials can be glued together using a visitor. However, brush bristle materials not only with different materials but also with different abrasive grains are not sufficiently bonded by adhesion (by adhesive), welding, or electrodeposition, especially when bonded by adhesive. There was a drawback that a bad odor was generated during grinding.

JP 2008-12125 A

  In the conventional brush bristle material, powder such as abrasive grains is mixed in or around the material that becomes the bristle. The brush bristle material and abrasive grains have different properties. It is difficult for the bristle material made of the different substances and containing different abrasive grains to have uniform welding or electrodeposition.

  When an adhesive is used for bonding, the bristle material often gives off a strange odor between the workpieces. The worker smelled the unpleasant odor all day and became uncomfortable.
