Mineralized decorative acoustic board and preparation process thereof

The invention relates to the technical field of decorative acoustic boards, in particular to a negative carbon steel slag-based mineralized decorative acoustic board and a preparation process thereof, the negative carbon steel slag-based mineralized decorative acoustic board can recover a large amount of steel slag difficult to treat and is high in strength, low in cost and good in water resistance, and the mineralized decorative acoustic board comprises the following components in percentage by mass: 55% of steel slag wool, 5% of 425 slag cement and 40% of tap water. The steel slag wool comprises the following components in percentage by mass: 8.3%-10.3% of molten steel slag and 89.7%-91.7% of desert aeolian sand. Molten steel slag is adopted as a main raw material, a large amount of waste steel slag difficult to treat can be consumed, the cost is low, energy is saved, waste is utilized, the comprehensive performance such as mechanical performance is higher, 425 slag cement is adopted as a binding agent, and
