Abstract

The invention belongs to the technical field of mahjong tiles, and particularly relates to a mahjong tile for a full-automatic mahjong machine, the mahjong tile comprises a shell, a shell cover, a core part and a magnet, one side of the core part is provided with an accommodating groove, the core part is arranged in the shell, the magnet is arranged in the accommodating groove, and the shell cover covers the shell. The core part is prepared from the following components in parts by weight: 50 to 70 parts of polyether polyol, 100 to 120 parts of isocyanate, 20 to 30 parts of a chain extender, 0.5 to 1.5 parts of a catalyst, 80 to 120 parts of hollow glass beads, 100 to 150 parts of loess, 1 to 3 parts of an expanding aid and 5 to 15 parts of water. According to the mahjong tile, the core part used for fixing the magnet is arranged between the shell and the shell cover, the core part generates the porous structure through foaming of the polyurethane and the loess, and the porous structure of the loess and the hollow glass beads are combined, so that the core part has good sound absorption and noise reduction effects; meanwhile, the hollow glass beads can effectively restrain structure defects caused by excessive volume expansion generated by high temperature and can effectively restrain volume shrinkage caused by hardening, so that the mass and the volume of the formed core part are both in a controllable range.

Description

Technical field [0001] The present application belongs to the technical field of mahjong, which specifically involves a full automatic mahjong machine. Background technique [0002] Mahjong originated in my country, which was originally a kind of game of the palace aristocratic leisure and entertainment, dating back to three or four thousand years. During the evolutionary evolution of mahjong, gradually evolved from the traditional manual code card to hear the automatic mahjong machine automatic code card, the mahjong machine lifted the mahjong brand through the magnet near the numbness, and then rotated with the magnetic circle The conveying slot and the four-sided card stack is stacked through the subsequent series of operations, and finally push it. Therefore, there is a need for a magnet in a mahjong card for the automatic mahjong machine. [0003] Due to the texture of the mahjong brand itself, the collision is easy to make sound, especially during the shuffle, it will make ...
