Detailed Description
The first aspect of the invention provides a sound-absorbing color rock plateThe surface density of the sound-absorbing color rock plate is 10-25 kg/m 2 。
In a preferred embodiment, the sound-absorbing color rock plate has an areal density of 15 to 20kg/m 2 (ii) a Further preferably, the sound-absorbing color rock plate has an areal density of 18kg/m 2 。
In one embodiment, the sound-absorbing color rock plate has a thickness of 6 to 15mm.
In a preferred embodiment, the sound-absorbing color rock plate has a thickness of 9 to 12mm; further preferably, the sound-absorbing color rock plate has a thickness of 10mm.
In one embodiment, the raw material of the sound-absorbing color rock plate comprises rock sand.
In one embodiment, dan Yansha is purchased from Gansu rock Sand, inc.
In one embodiment, the total weight fraction of the raw materials of the sound-absorbing color rock plate is 100%.
In a preferred embodiment, the raw material of the sound-absorbing color rock plate further comprises attapulgite, wherein the weight of the attapulgite is 4 to 10% of the weight of the raw material of the sound-absorbing color rock plate.
In a more preferred embodiment, the weight of the attapulgite is 6 to 8% of the weight of the raw material of the sound-absorbing color rock plate; more preferably, the weight of the attapulgite is 7% of the weight of the raw material of the sound-absorbing color rock plate.
In one embodiment, the attapulgite is purchased from new materials technologies, inc.
The applicant finds that the color rock plate can be prepared into a plate after demolding without using an adhesive, so that the surface density of the color rock plate is further controlled. Probably because the attapulgite in the invention has a transitional layer chain structure and also has a certain fibrous crystalline structure and a rod-shaped structure, in the process of preparing the color rock plate by sintering, the structure of the disorderly accumulated needle rod-shaped clusters of the attapulgite is changed, so that the surface density of the color rock plate is increased, and in the invention, the attapulgite with a certain content and the foaming agent are cooperated to reasonably control the surface density of the color rock plate.
In one embodiment, the raw material of the sound-absorbing color rock plate further comprises a foaming agent.
In a preferred embodiment, the weight of the foaming agent is 0.2 to 1% of the weight of the raw material of the sound-absorbing color rock plate.

According to the invention, the surface density of the color rock plate is controlled by controlling the amount of the foaming agent in the system, so that the color rock plate has good flame retardant property. This is probably because when the amount of the foaming agent is small, the amount of the generated bubbles is small and the area density is large, and when the amount of the foaming agent is large, the number of foaming sites increases to form interconnected pores between the bubbles, and the increase of the interconnected pores increases the flame retardant property to some extent, but because the amount of the foaming agent is too large, the gas emitted during the production of the color rock plate is too much, and even the gas in other components in the system is released, resulting in the decrease of the area density.
In one embodiment, the foaming agent consists of sodium bicarbonate, perlite, n-hexane.
In a preferred embodiment, the weight ratio of the sodium bicarbonate, the perlite and the n-hexane is (2-3): (1.5-2): 1; further preferably, the weight ratio of the sodium bicarbonate to the perlite to the n-hexane is 2.5:1.8:1.
In one embodiment, the perlite is purchased from Zhejiang sanderian haydite construction materials, inc.

In a preferred embodiment, the weight of the placer is 2 to 5 percent of the weight of the raw material of the sound-absorbing color rock plate; further preferably, the weight of the placer ore is 2.5% of the weight of the raw material of the sound-absorbing color rock plate.
In one embodiment, the placer is purchased from a commercial mineral processing plant in Leishui City.
The second aspect of the present invention provides a method for preparing a sound-absorbing color rock plate, comprising the steps of:
(1) Uniformly mixing the rock sand, the attapulgite and the foaming agent of the sound-absorbing color rock plate, and putting the mixture into a ball mill for ball milling;
(2) Putting the raw materials subjected to ball milling into a ceramic press for dry pressing forming to obtain a green body of the color rock plate;
