ポリエステル樹脂成形材料に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to unsaturated polyester resin molding used for molded products that particularly require strength and durability, such as housing (tables, construction components, sanitary equipment, etc.) It's about materials.

圧成形ができなｈ欠点があ−た。Conventionally, unsaturated polyester resin molded products have high strength and durability.
This is excellent, but because the molding material has good fluidity during molding,
Large molded products can be molded by low-pressure molding, but on the other hand, material tends to come out from the mold parting surface, and sufficient pressure is not applied to the inside of the mold, that is, the molded product, resulting in pinholes and poor gloss. There was a problem. As a countermeasure to this problem, attempts have been made to reduce the fluidity of the molding material, but this method has the disadvantage that low-pressure molding cannot be performed.

ポリエステルｍ脂成形材料を提供することｌこある。As described in the prior art, since unsaturated polyester resin molding materials have good fluidity, they pose serious problems in that they cause pinholes and poor gloss. The present invention was made in view of the above-mentioned problems in the conventional technology, and its purpose is to obtain a molded product without pinholes or gloss defects while maintaining high strength and durability. It is an object of the present invention to provide an unsaturated polyester resin molding material.

詳細な説明する。The present invention uses an unsaturated polyester resin, a crosslinking agent, a mold release agent,
An unsaturated polyester resin molding material comprising a polymerization initiator, a filler, a reinforcing agent, a coloring agent, and, if necessary, a thermoplastic aw+ resin, an unsaturated polyester resin molding material containing a melamine resin. Because it is a polyester resin molding material,
The present invention has been able to achieve the above object, and will be described in detail below.

用りることができる。The unsaturated polyester resin used in the present invention is not particularly limited, and any unsaturated polyester resin can be used. As the crosslinking agent, one that is liquid at room temperature or solid at room temperature, such as styrene monomer, can be used, and although this is not limited to, diallyl phthalate monomer is preferably used to improve heat resistance. In addition, the heat resistance can be further improved by incorporating trigammalylyl insiamerate in combination with a crosslinking agent to increase the crosslinking density. As the melamine resin, it is desirable to use powder or fine particles of solid melamine resin, with a particle size of 1
It is preferable that the content of particles of 0.00 microns or more is 7 on (hereinafter simply referred to as "excellent"). The amount added is 1~ of the total amount.
A score of 30 is preferred. That is, if it is less than 1%, it is difficult to reduce fluidity, and if it exceeds 30%, heat resistance tends to decrease. As fillers, pulp, wood flour, calcium charcoal, clay, silica, talc, aluminum hydroxide, etc. can be added. There are no particular limitations on thermoplastic resins as low-shrinkage agents, glass fibers, reinforcing agents such as glass fiber chips, crosslinking agents, polymerization initiators, mold release agents, coloring agents, etc., and commonly used ones can be used. It can be used as is.
