Problems solved by technology

Because the existing foamed bricks are relatively thick and the formula system is difficult to oxidize, the formula system of the foamed ceramics determines that it must be fired in a tunnel kiln. The firing cycle of the tunnel kiln is about 24-26 hours, and the firing cycle is long. , higher temperature
[0005] And, if figure 1 As shown, the foamed ceramic plate made by the prior art has multi-layer pores formed inside
During the foaming process, due to the long foaming time and the influence of gravity, the pores in the lower layer will be flattened, making the overall uniformity of the product poor

preparation example Construction

[0061] like figure 2 As shown, the present invention provides a kind of preparation method of foamed ceramic light board, comprising:

[0062] S101, mixing the raw materials according to the proportion, and ball milling to make powder;

[0063] The ball milling can be wet milling or dry milling. The wet milling process includes: adding 30-40% water to the raw material, putting it into a ball mill for ball milling, milling until the residue on a 250-mesh sieve is less than 1%, and then passing through a spray tower to mill powder to obtain a water content of 5-40%. 10% powder.

[0064] S102, distributing the powder to obtain a green body;

[0065] S103, firing the green body through a roller kiln or a tunnel kiln to obtain a semi-finished product;

[0066] S104, cutting and grinding the semi-product to obtain a finished product.

[0067] After firing, the upper and lower surfaces of the semi-finished product need to be ground and the edges should be cut.

[0068] Due to ...

Embodiment 1

[0086] (1) Formula: tile polishing waste 95.5%, foaming agent 0.5%, manganese dioxide stabilizer 4%.

[0087] (2) Preparation method:

[0088] The above raw materials are mixed according to the proportion, transported to the ball mill for ball milling, and sieved to a 250-mesh sieve with a residue of less than 1%, and then through the slurry storage tank and transfer tank to the spray tower for spray granulation, and the obtained powder The material is distributed by the feeding cart, and then enters the roller kiln for firing. The firing time is 10 hours and the firing temperature is 1100°C. Finally, it is cut and ground to obtain the finished product.

Embodiment 2

[0090] (1) Formula: tile polishing waste 90%, clay 1%, feldspar 8.8%, foaming agent 0.1%, stabilizer 0.1%.

[0091] (2) Preparation method:

[0092] The above raw materials are mixed according to the proportion, transported to the ball mill for ball milling, and sieved to a 250-mesh sieve with a residue of less than 1%, and then through the slurry storage tank and transfer tank to the spray tower for spray granulation, and the obtained powder The material is distributed by the feeding cart and then enters the roller kiln for firing. The firing time is 12 hours and the firing temperature is 1150°C. Finally, it is cut and ground to obtain the finished product.

Abstract

The invention discloses a foam ceramic light-weight plate, which is mainly prepared from the following raw materials in percentage by weight: 70 to 96 percent of ceramic tile polished waste slag, 0 to10 percent of clay, 0 to 20 percent of feldspar, 0.01 to 0.6 percent of foaming agents and 0.1 to 4 percent of stabilizing agents, wherein the stabilizing agents are manganese dioxide. Correspondingly, the invention also provides a preparation method of the foam ceramic light-weight plate. By using the foam ceramic light-weight plate and the preparation method, air holes are identical from top tobottom at the same cross section of the foam ceramic light-weight plate; the bubble uniformity is high; a tunnel kiln can be used for firing; a roller kiln can also be used for firing.

Description

technical field [0001] The invention relates to the technical field of lightweight plates for construction, in particular to a foamed ceramic light plate and a preparation method thereof. Background technique [0002] The matrix materials used in foamed ceramics come from wastes such as ceramic factory waste and industrial waste (tile polishing waste or cinder or stone waste, etc.). If these wastes are not treated, they will be piled up or landfilled randomly. Waste of resources. [0003] This foamed ceramic product has gradually begun to be used nationwide due to its advantages of light weight, high strength, fire prevention, earthquake resistance, heat insulation, sound insulation, strong combination, easy handling, and wide application. And because the raw materials are solid wastes such as coal slag, tile polishing waste, slag, etc., it has positive social significance in terms of full utilization of resources and environmental protection. [0004] The formula system o...
