ていた。Melamine resin molded products made by heat-pressing and hardening melamine resin molding materials are hard and durable, but because they lack flexibility, they are susceptible to impact, bending, and tensile elongation, making them susceptible to damage or damage to the crank. There was a problem. The melamine resin obtained by further reacting formaldehyde with the reaction product of melamine with polyethylene glycol glycidyl ether has a crosslinked structure with a soft segment of CH=CH-CH2- formed by modification of a glycidyl compound. A technique that can solve the problem is disclosed in Japanese Patent Application Laid-Open No. 5947253. Although melamine resin molded products made using this technology have considerable impact resistance, they still have the problem of being weak against tensile elongation and lacking in flexibility.
本発明は、引張の伸びに強いメラミン樹脂の成形品を形

ある。[Means for Solving the Problems] In order to solve the above problems, the present inventor has developed Melamine 100.
The object of the present invention is to provide a melamine resin molding material characterized in that it contains a melamine resin obtained by reacting 80 to 500 parts by weight of diglycidyl ether with parts by weight.

脂を得ることができないからである。The blending amount of these glycidyl ethers is melamine 100
80 to 500 parts by weight (hereinafter simply referred to as parts)
It is necessary to set the range in the section. This is because if the blending amount of glycidyl ether is less than 80, the modification with glycidyl ether will be insufficient and it will not be possible to impart high flexibility to the melamine resin, and if the blending amount exceeds 500, glycidyl ether This is because if the amount of ether becomes too large, melamine tends to gel, making it impossible to obtain melamine resin.
