Problems solved by technology

With the popularization of the mahjong machine home market, people have higher and higher requirements for the surface performance of the mahjong machine. The plastic casing of the existing mahjong machine has poor wear resistance and is easy to age. After being rubbed repeatedly, after a long time, the surface is prone to wear and tear. At the same time, with the existence of aging phenomenon, the working life of the mahjong machine shell will drop sharply. The mahjong machine shell is a part of the main part of the mahjong machine’s normal work. The decline in performance will directly cause the entire mahjong machine to fail to work normally, and then directly reduce the service life of the entire mahjong machine

Abstract

The invention discloses a wear-resistant plastic shell of a Mahjong machine, and relates to the technical field of preparation of a Mahjong machine. The wear-resistant plastic shell of the Mahjong machine is prepared from the following components: ABS resin, a plasticizer, a dispersing agent, fillers, modified nanometer zinc oxide and activated diatomite coordinated starch. The wear-resistant plastic shell of the Mahjong machine, provided by the invention, has high wear resistance, also has high tensile property and can obviously prolong the service life of the Mahjong machine.

Description

technical field [0001] The invention belongs to the technical field of mahjong machine preparation, in particular to a wear-resistant plastic shell of a mahjong machine. Background technique [0002] Mahjong machine has been rapidly promoted because of its convenience for consumers. Existing mahjong machines can be roughly divided into two types according to the way of entering cards: a single-port machine for entering cards in a single way and a four-port machine for entering cards from four sides. When the mahjong machine industry emerged, single-port machines dominated the mainstream, and later four-port machines dominated the mainstream. With the popularization of the mahjong machine home market, people have higher and higher requirements for the surface performance of the mahjong machine. The plastic casing of the existing mahjong machine has poor wear resistance and is easy to age. After being rubbed repeatedly, after a long time, the surface is prone to wear and tea...
