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] [Industrial Application Field] The present invention is directed to an unsaturated polyester resin molding material that can be used to produce molded products that particularly have low specific gravity, appearance, and satisfy the Food Sanitation Act, such as for tableware. It is related to.

法を満足させ得ない。Conventionally, when unsaturated polyester resin molding material is used for tableware, it becomes a molded product with a high specific gravity, making it unsuitable for use in tableware. If the unsaturated polyester resin molding material is made foamable, the appearance of the molded product deteriorates, and in either case, the food hygiene law cannot be satisfied.

ポリエステル樹脂成形材料を提供するととＩこある。As described in the prior art, even unsaturated polyester resin molding materials and foamable materials thereof can be used for tableware. The present invention has been made in view of the above-mentioned problems in the conventional technology, and its purpose is to provide an unsaturated polyester resin molding material that can yield molded products that satisfy the requirements of low specific gravity, appearance, and food hygiene. I have something to offer.

細な説明する。The present invention is an unsaturated polyester resin molding material prepared by adding a thermoplastic resin, a filler, a reinforcing agent, a crosslinking agent, a polymerization initiator, a mold release agent, a spring coloring agent, etc. to an unsaturated polyester resin. At least bulk density 0.1-0.3 y/a
An unsaturated polyester characterized by containing 5 to 25% of the total amount of a"o glass balloons (hereinafter simply referred to as "regret") and 5 to 25% of the total amount of aluminum hydroxide with an average particle size of 1 to 10 microns. The above object can be achieved by using the pain fat-like material, and the present invention will be described in detail below.

。The unsaturated polyester resin used in the present invention is not particularly limited, and any unsaturated polyester resin can be used. Fruit 1! 11 can be a liquid at room temperature or a solid at room temperature, such as styrene monomer.Although it is not limited to this, it is preferable to use diallyl phthalate monomer in order to improve heat resistance. It is also possible to further improve heat resistance by incorporating triallyl isocyamelate in combination with an agent to increase the crosslinking density. As a filler, C must contain at least 35 pieces of O-glass balloons with a bulk density of 0.1 to 0.3 f7f7. In the shape material manufacturing process 1, it is crushed and the specific gravity is not reduced, l), 3 f/ /
This is because if it exceeds cmk, it will fail the Food Sanitation Act. In addition, if the addition port is less than b, the specific gravity will not be lowered and 35%
This is because if it exceeds the appearance, the food hygiene law will be rejected. Furthermore, it is necessary to contain 5 to 25% of the total amount of aluminum hydroxide having an average particle size of 1 to 10 microns.

加量が５僑未満では威嚇性が低下し、２５優ヲこえると
低比重化にならなめためである。In other words, if the average particle size is less than 1 micron, the specific gravity will not be lowered,
This is because if the amount exceeds 10 microns, the appearance deteriorates, if the amount added is less than 5 microns, the threatening effect decreases, and if the amount exceeds 25 microns, the specific gravity becomes low.

用論ることができる。There are no particular limitations on thermoplastic resins, glass fibers, reinforcing agents such as glass fiber tape, crosslinking agents, polymerization initiators, mold release agents, right coloring agents, coupling agents, etc. as low-yielding agents, but as necessary. Depending on the situation, the one normally used can be used as is.
