Embodiment 1

[0025] A gypsum board capable of releasing negative oxygen ions, the gypsum board is made by adding expanded vermiculite and tourmaline to common gypsum board raw materials according to a conventional gypsum board preparation method, wherein the added amount of expanded vermiculite is gypsum 55% of the total weight of the board raw materials, and the addition of tourmaline is 0.4% of the total weight of the gypsum board raw materials.

[0026] The vermiculite is expanded vermiculite obtained by placing the raw material of vermiculite in an extruding furnace at 600° C. for 10 seconds and expanding it; the particle size of the expanded vermiculite is 0.5 mm. The particle size of the tourmaline is 200 mesh.

Embodiment 2

[0028] A gypsum board capable of releasing negative oxygen ions, the gypsum board is made by adding expanded vermiculite and tourmaline to common gypsum board raw materials according to a conventional gypsum board preparation method, wherein the added amount of expanded vermiculite is gypsum 56% of the total weight of the board raw materials, and the addition of tourmaline is 0.5% of the total weight of the gypsum board raw materials.

[0029] The vermiculite is expanded vermiculite obtained by placing the raw material of vermiculite in an extruding furnace at 900° C. for 10 seconds and expanding it; the particle size of the expanded vermiculite is 4 mm.

[0030] The particle size of the tourmaline is 6000 mesh.

Embodiment 3

[0032] A gypsum board capable of releasing negative oxygen ions, the gypsum board is made by adding expanded vermiculite and tourmaline to common gypsum board raw materials according to a conventional gypsum board preparation method, wherein the added amount of expanded vermiculite is gypsum 50% of the total weight of the board raw materials, and the addition of tourmaline is 0.1% of the total weight of the gypsum board raw materials.

[0033] The vermiculite is expanded vermiculite obtained by placing the raw material of vermiculite in an extruding furnace at 800° C. for 10 seconds and expanding it; the particle size of the expanded vermiculite is 2 mm. The particle size of the tourmaline is 2000 mesh.

Abstract

The invention relates to a gypsum board capable of releasing negative oxygen ions, wherein the gypsum board is prepared by adding expanded vermiculite and tourmaline to raw materials of a common gypsum board, wherein the addition amount of the expanded vermiculite is 50-60% of the total weight of the raw materials of the common gypsum board while the addition amount of the tourmaline is 0.1-1% of the total weight of the raw materials of the common gypsum board. Compared with the gypsum board in the prior art, the gypsum board can release negative oxygen ions, is environmental-protective and is strong in practicability.

Description

technical field [0001] The invention relates to a gypsum board, in particular to a gypsum board capable of releasing negative oxygen ions. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc. [0003] Due to the advancement of technology, scientists have discovered that there are positively charged ions (positive ions) in the surrounding atmosphere of airtight buildings (including office buildings and other indoor areas). Scientists suggest neutralizing positive ions and increasing the conce...
