詳細に説明する。INDUSTRIAL APPLICABILITY The present invention uses a fibrous magnesium silicate compound as a filler in an unsaturated polyester resin molding material obtained by adding a filler, a cross-linking agent, a polymerization initiator, a release agent, a colorant, etc. to an unsaturated polyester resin. It is characterized in that it is possible to obtain an unsaturated polyester resin molded article excellent in flame resistance and wear resistance by heating and molding the molding material thus obtained, and the present invention will be described below. The details will be described.

As the cross-linking agent, a liquid at room temperature such as a styrene monomer or a solid at room temperature can be used, but it is not limited thereto, but it is preferable to use a diallyl phthalate monomer for improving heat resistance. The heat resistance can be further improved by blending triallyl isocyanurate in combination with the agent to increase the crosslinking density.

に優れた成形品を得ることができるものである。As the filler, at least a fibrous magnesium silicate compound is used. As fibrous magnesium silicate, chrysotile [Mg 6 Si 4 O 10 (OH) 8 ] and ceviolite [Mg 8 Si 12 O 30 (OH) 4 (H 2 O) 4 8H 2 O] trade name Adeplus 55 [ Takeda Pharmaceutical Co., Ltd., main component SiO 2・ MgO
-Al 2 O 3 ] and the like, and also includes all fibrous substances containing CaO, H 2 O and the like with magnesium silicate as a main component. The amount of the fibrous magnesium silicate-based compound is preferably 3 to 80% by weight (hereinafter simply referred to as "%") of the total amount. That is, if it is less than 3%, it is difficult to improve the crack resistance, and if it exceeds 80%, the moldability tends to decrease. As a filler other than the fibrous magnesium silicate compound, pulp, wood powder, calcium carbonate, glass fiber, clay, silica, talc, etc. can be added. The polymerization initiator, mold release agent, colorant or surfactant, thickener, etc., which are added as necessary, are not particularly limited, and those commonly used can be used as they are. The unsaturated polyester resin molding material thus obtained can be molded under heat and pressure by compression molding, extrusion molding, transfer molding, injection molding or the like to obtain a molded article having excellent flame resistance and abrasion resistance.
