持つ弾性が十分に生かせないという問題点がある。(Problem to be Solved by the Invention) However, conventional non-woven abrasive materials are entirely covered with a synthetic resin layer containing abrasive grains, which poses a problem in that the inherent elasticity of synthetic fibers cannot be fully utilized. There is.

There is. Furthermore, when abrasive grains are dispersed in a synthetic resin matrix, the inherent elasticity of the synthetic resin is reduced.

性樹脂により、積層一体化し上記課題を解決した。Therefore, a nonwoven abrasive material that satisfies all of the requirements of elasticity, abrasive power, durability, safety, and workability is desired. (Means for Solving the Problems) In view of the current situation, the present invention provides a composite nonwoven abrasive material that has excellent elasticity, workability, and safety, as well as excellent abrasive power and durability. be. That is, in the present invention, on the surface of a base fiber layer formed by temporarily fixing the fibers of a web made of synthetic fibers to each other with a composite resin, abrasive abrasive grains are added at a rate of 50-1 to 100 parts by weight of a thermosetting resin. A nonwoven fabric abrasive base material A partially covered with an abrasive-containing layer containing 0.000% and fixed in the form of dots, and a nonwoven fabric B made by temporarily fixing the fibers of a web made of synthetic fibers with a synthetic resin, are made of a thermosetting elastic resin. The above problem was solved by integrating the layers.

低下を持たらす。The synthetic fibers that make up the nonwoven abrasive substrate A include polyamide, polyester, acrylic, and polyvinylidene chloride, but from the viewpoint of workability of the abrasive-containing dot layer, a fineness of 3 to 30 denier is used. It is preferable to have one. In particular, when fibers of 30 denier or more are used, the adhesion area between the fibers and the abrasive-containing layer decreases, resulting in insufficient adhesive strength of the abrasive-containing layer, resulting in a drop in durability due to falling off.

低下し耐久性に劣るので好ましくない。In addition to alundum, carborundum, garnet, emery, diamond sand, etc., commercially available abrasive grains and, in some cases, aluminum powder, glass beads, and resin particles are added to the base fiber layer using a thermosetting resin (for example, phenol). , epoxy, urea-formaldehyde, urethane, isocyanurate resin, etc., each singly or in an appropriate mixture), is partially coated and fixed in dots with an abrasive-containing layer containing 50 to 1,000 parts by weight per 100 parts by weight. Polishing base material A
get. If the ratio of abrasive grains to thermosetting resin is less than 50 parts by weight, the polishing power will be poor, and if it exceeds 1,000 parts by weight, the gripping force of the abrasive grains by the thermosetting resin will decrease, resulting in poor durability. I don't like it because it's inferior.

Those with fineness are preferred. Furthermore, by attaching abrasive grains to the nonwoven fabric, the resulting composite nonwoven fabric according to the present invention has even better abrasive power.

It is also possible to create a so-called ganged wheel or unified wheel that is integrated afterwards. In addition, nonwoven fabric polishing base material A and nonwoven fabric B
It is also possible to form a so-called convoluted wheel by winding the laminated layers around a shaft core, heating and curing them using thermosetting elastic resins such as urethane resin and isocyanurate resin, and then integrating them. These wheel-shaped composite nonwoven abrasive materials are particularly used in automatic polishing machines, and are expected to improve workability and efficiency.
