A floor tile suitable for laying floor heating and its manufacturing method

Abstract

The invention discloses a floor tile applicable to laying of a floor heating system. Raw materials for a green body of the floor tile comprise, by weight, 10 to 15% of ferrochromium slag, 20 to 30% of fly ash, 15 to 25% of medium-temperature sand, 5 to 12% of low temperature potassium-sodium sand, 10 to 15% of black talc, 6 to 15% of composite soil, 6 to 10% of washed pure mud, 1 to 3% of lithium porcelain stone and 1 to 3% of magnesian black clay. Moreover, the invention also discloses a manufacturing method for the floor tile applicable to laying of the floor heating system. According to the invention, waste slag is used as a main raw material, so the waste is utilized, and the obtained floor tile is applicable to laying of the floor heating system, presents a good far-infrared emission function, benefits the health of the human body and has good heat stability and strength. The raw materials are easily available and cheap, so raw material cost and production cost are substantially reduced, energy conservation and emission reduction are realized, and production and industrial promotion and application are benefited.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a floor tile suitable for laying floor heating and a manufacturing method thereof. Background technique [0002] Geothermal heating, that is, through floor radiation heating, the temperature radiates from the ground upwards and decreases from bottom to top, making the indoor temperature uniform. The heating method of floor heating has the following advantages: [0003] (1) heating and comfort. The room temperature of the room with floor heating decreases from bottom to top as the height increases. At the same time, the indoor surface temperature is uniform and the air quality is good. [0004] (2) Energy saving and high efficiency. The heat dissipation of the ground heating method is mainly concentrated in the height where the human body benefits, so the thermal efficiency is high. Since the circulating water for heating only needs to be between 50 and 60°C...

Problems solved by technology

However, the floors used in the floor heating method are mostly wooden floors at present, and there are the following defects in the use process: First, there is dust under the wooden floor, which will easily lead to poor airtightness of the wooden floor due to thermal expansion and contraction after long-term use, resulting in The dust is flying; the second is that the wooden floor is bonded with glue, which will produce toxic gas when heated by floor heating, which will affect the health of the body

For this reason, in recent years, ceramic products such as microcrystalline tiles and polished tiles have also been researched and developed as floors for floor heating. However, these ceramic products in the current prior art also have phenomena such as glaze peeling and tile cracking due to thermal expansion and contraction; And what brings is solid heat radiation, not only the temperature is high, but also it will cause the air to be dry, the human body is easy to dehydrate, and the comfort is poor.
