Problems solved by technology

However, organic polymer materials are prone to creep and relaxation under the action of environmental factors such as light, heat, humidity, stress, and corrosive media, etc. Chemical aging with structural changes, which leads to material performance degradation and affects the long-term use of materials
In addition, the current preparation process of non-combustible boards still has problems such as complicated processes and formulas, and difficult control.

Embodiment 1

[0023] This embodiment relates to a preparation method of a non-combustible material; the preparation method includes the following steps:

[0024] The first step is to configure the electrodeposition solution: the solvent in the electrodeposition solution is ethylene glycol, and the solute component and the corresponding molar concentration are: aluminum nitrate (Al(NO 3 ) 3 )0.15mol / L, zirconium nitrate pentahydrate (Zr(NO 3 ) 4 ·5H 2 O) 0.2mol / L;

[0025] The second step is to prepare aluminum-zirconium precursor materials by electrodeposition: inject the electrodeposition solution described in the first step into the electrodeposition tank; put graphite into the electrodeposition tank as the cathode, and put graphite into the electrodeposition tank as the anode middle; the cathode is in full contact with the electrodeposition solution in the electrodeposition tank, while avoiding the contact between the cathode and the anode (the distance between the cathode and the an...

Embodiment 2

[0028] This embodiment relates to a preparation method of a non-combustible material; the preparation method is basically the same as in Example 1; the difference is:

[0029] In the first step, the solute components and corresponding molar concentrations in the electrodeposition solution are: aluminum nitrate (Al(NO 3 ) 3 )0.1mol / L, zirconium nitrate pentahydrate (Zr(NO 3 ) 4 ·5H 2 O) 0.02mol / L;

[0030] In the second step, the temperature of the electrodeposition solution is controlled to be 20°C, the pulse deposition voltage is controlled to be 20V, the on-time is 1s, and the off-time is 1s;

[0031] In the third step, the aluminum-zirconium precursor material obtained in the second step is heated at 250° C. for 25 minutes. Inductively coupled plasma mass spectrometry analysis of the finally prepared aluminum-zirconium oxide non-combustible material shows that it includes the following elements by weight percentage: aluminum: 83%, zirconium: 17%.

Embodiment 3

[0033] This embodiment relates to a preparation method of a non-combustible material; the preparation method is basically the same as in Example 1; the difference is:

[0034] In the first step, the solute components and corresponding molar concentrations in the electrodeposition solution are: aluminum nitrate (Al(NO 3 ) 3 )0.2mol / L, zirconium nitrate pentahydrate (Zr(NO3 ) 4 ·5H 2 O) 0.4mol / L;

[0035] In the second step, the temperature of the electrodeposition solution is controlled to be 30°C, the pulse deposition voltage is controlled to be 10V, the on-time is 2s, and the off-time is 1s;

[0036] In the third step, the aluminum-zirconium precursor material obtained in the second step is heated at 200° C. for 50 minutes. Inductively coupled plasma mass spectrometry analysis of the finally prepared aluminum-zirconium oxide non-combustible material shows that it includes the following elements by weight percentage: aluminum: 55%, zirconium: 45%.

Abstract

The invention discloses a preparation method of a noncombustible material. The preparation method comprises the following steps: preparing an electrodeposit solution in which the solvent is glycol, and the solute components in corresponding molar concentration are as follows: 0.1-0.2mol / L of aluminum nitrate and 0.02-0.4mol / L of zirconium nitrate pentahydrate; separately using graphite as a cathode and an anode, and performing a pulse electrodeposit reaction in the electrodeposit solution to obtain an aluminum zirconium precursor material; and heating the aluminum zirconium precursor materialat 200-250 DEG C for 25-50 minutes, and performing cooling in furnace to obtain the aluminum zirconium oxide noncombustible material. The prepared noncombustible material does not contain any organicsubstances, and cannot encounter physical or chemical aging problems commonly seen in polymer organic substances; and the material is composed of aluminum oxide and zirconium oxide which are both hightemperature-resistant materials with high chemical stability, the aluminum oxide can provide the noncombustible material with good mechanical strength, and the addition of the zirconium oxide can provide the noncombustible material with certain plasticity.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a preparation method of non-combustible materials. Background technique [0002] With the continuous improvement of fire safety requirements in public places and family residences, the fire performance of materials has been valued by more and more design and construction units and users. At the same time, our country has also promulgated a series of laws and regulations, policy provisions, etc. to support the development of fire-resistant and flame-retardant materials that can meet the national fire protection standards. Against this background, various new types of non-combustible panels have been developed. [0003] The Chinese patent "non-combustible decorative board" with the notification number CN103243881B discloses a non-combustible decorative board with cement as the main component of an inorganic substrate and an airtight surface decorative layer.
