Problems solved by technology

[0003] However, the main disadvantages of the existing boards are: 1. The strength is not high enough, the strength of raw materials is only 2.3-2.5 MPa in 2 hours, easy to deform, low breaking load, and low density; 2. The whiteness is not high enough, the whiteness of the existing raw materials The hardness is only 82-85 degrees; 3. The hardness is low, and the Mohs hardness is only between 2.5-3

preparation example Construction

[0070] According to a second aspect of the present invention, there is provided a method for preparing a titanium-calcium plate, comprising the following steps:

[0071] First mix β gypsum powder, titanium dioxide, optional antibacterial agent, optional adsorbent and optional negative oxygen ion release agent, then age, homogenize, and then fluidize into the silo, and then the ingredients enter the molding process, The formed product is exposed to sunlight to obtain a titanium-calcium plate.

[0072] Preferably, on the basis of the preparation method provided by the present invention, the titanium dioxide is nanoscale titanium dioxide.

[0073] Preferably, based on the preparation method provided by the present invention, the addition amount of titanium dioxide is 10-15 wt%.

[0074] Typical but non-limiting percentages of titanium dioxide added are, for example, 10%, 11%, 12%, 13%, 14%, and 15%.

[0075] Preferably, the mixing process is performed using a high-speed separat...

Embodiment 1

[0092] A preparation method of titanium-calcium plate, comprising the following steps:

[0093] Add 100kg of nanoscale titanium dioxide, 10kg of antibacterial agent-penicillin powder, 10kg of adsorbent-formaldehyde adsorbent and 10kg of negative oxygen ion release agent-negative oxygen ion powder into 870kg of β gypsum powder, and mix them thoroughly through a high-speed separator. form titanium-calcium composites. Subsequently, the composite material is poured into an aging homogenization bin equipped with an ultraviolet generator, and after aging and homogenizing for 8 hours, it is fluidized into the bin. Then carry out batching, according to the ratio of powder to water 1kg:0.6kg, that is, add 0.6kg of water to 1kg of dry powder, stir it into a slurry of standard consistency, and enter the molding process. Finally, the molded product was exposed to the sun for 3 days to obtain a titanium-calcium plate, and its crystal morphology is as shown in the attached figure 1 shown....

Embodiment 2

[0096] The difference between this example and Example 1 is that the amount of nano-scale titanium dioxide added is different, and the amount of added titanium dioxide in this example is 13 wt%.

[0097] After testing, the 2-hour flexural strength of the titanium-calcium plate prepared by the method of this example is 4.3 MPa, the Mohs hardness is 7.3, and the whiteness is 89 degrees.

Abstract

The invention provides a titanium-calcium plate and a preparation method thereof, and relates to the technical field of building decoration materials. The titanium-calcium plate comprises the following components in percentage by mass: 80-90% of beta gypsum powder, 10-15% of titanium dioxide, 0-3% of an antibacterial agent, 0-2% of an adsorbent and 0-5% of a negative oxygen ion releasing agent. The problems that an existing plate is not high enough in strength, low in breaking load, not high enough in whiteness, low in hardness and the like are mainly solved. According to the titanium-calciumplate, the breaking strength within 2 hours can be improved to 4.5 MPa or above, the Moh's hardness can also be improved to 7-7.5, the whiteness can also reach 88-90 degrees, and a very satisfactory technical effect is achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a titanium-calcium board and a preparation method thereof. Background technique [0002] Titanium-calcium board is a kind of board with strong antibacterial ability, wide antibacterial range and good water resistance. Its core performance lies in decomposing and purifying formaldehyde, continuously releasing negative oxygen ions, antibacterial, anti-mildew and deodorizing properties, phase change energy storage and self-breathing. The titanium-calcium plate can oxidize and decompose harmful substances through photocatalysis under sunlight or weak indoor light, thereby reducing the concentration of harmful substances in the air and reducing or eliminating environmental discomfort. In addition, it also has performance characteristics such as antibacterial and sterilization, aldehyde absorption and aldehyde removal, oxygen enhancement and deodorization, fire prevention a...
