Problems solved by technology

[0003] At present, for the perforated gypsum board that uses paper-faced gypsum board as the base material, the perforation pattern is determined by the customized mold and the hole processing method. The color of the facial paper will change after a long time, or it will become dirty due to the harsh environment of use, the overall look and feel will become poor, the use effect will be limited, and the appearance and function will be relatively simple; moreover, due to the application of many chemical decoration materials, formaldehyde has become an important part of decoration in our country. one of the main pollutants

preparation example Construction

[0045] The application also provides a preparation method for the perforated gypsum board, which includes the following steps:

[0046]A preparation method for perforated gypsum board, comprising the following steps:

[0047] A), perforate in the direction perpendicular to the plasterboard;

[0048] B), the upper surface and the lower surface of the gypsum board obtained in step A) are respectively laid with the first face paper and the second face paper, and the mixed powder formed by the following components is sprayed on the first face paper : 40wt% ~ 55wt% diatom ooze, 1 ~ 3g / kg nano TiO 2 / Diatomite composite photocatalytic material and 3-4g / kg hydrogen-containing silicone oil;

[0049] Spray gypsum-based diatom mud on the surface of the hole, and the gypsum-based diatom mud includes nano-TiO 2 / Diatomite composite photocatalytic material;

[0050] Lay a sticking film on the surface of the second face-protecting paper.

[0051] In the process of preparing the perfora...

Embodiment 1

[0063] Perforate the base gypsum board with a size of 600×600mm and a thickness of 9mm, lay a protective paper on the upper surface of the paper-faced gypsum board, lay a water-resistant protective paper on the lower surface, and spray the following components on the surface of the water-resistant protective paper. Mixed powder (the diatom ooze of 45wt%, the nanometer TiO of 3g / kg 2 / diatomite composite photocatalytic material, 4g / kg hydrogen-containing silicone oil, 45wt% hemihydrate gypsum, 10wt% lime and 30g / kg inorganic pigment), spray twice to form a 3mm thick finish layer, In-pore spraying of gypsum board containing 3wt‰ nano-TiO 2 The diatom ooze of / diatomite composite photocatalytic material is laid on the surface of the protective paper, and the film is a film obtained by a two-way PET stretched corona film through surface aluminization, forming such as Figure 7 The perforated plasterboard.

Embodiment 2

[0065] The same as the preparation method of Example 1, the difference is: the raw materials in the finishing layer include: 52wt% diatom ooze, 1g / kg nano TiO 2 / diatomite composite photocatalytic material, 3.5g / kg hydrogen-containing silicone oil, 41wt% hemihydrate gypsum, 7wt% lime and 20g / kg inorganic pigment. The formaldehyde decomposition rate of the perforated gypsum board obtained in this example can reach 75-80% after being exposed to light for 72 hours.

Abstract

The invention provides a perforated gypsum plaster board. The gypsum plaster board comprises a gypsum plaster board body and holes vertically penetrating through the gypsum plaster board body. The gypsum plaster board body comprises a facing layer, first face protecting paper, a base plate, second face protecting paper and an adhesive film which are sequentially stacked. The holes are filled with gypsum-based diatom ooze. The gypsum-based diatom ooze contains a nano TiO2 / diatomite composite photocatalytic material. The facing layer is prepared from, by weight, 40-55% of diatom ooze, the nano TiO2 / diatomite composite photocatalytic material with the content being 1-3 g / kg and hydrogen-containing silicon oil with the content being 3-4 g / kg. The invention further provides a preparation method and an application method of the perforated gypsum plaster board. The gypsum plaster board has the adsorption and formaldehyde decomposition functions by adding diatom ooze and the photocatalytic material to the facing layer of the perforated gypsum plaster board and adding the photocatalytic material into the holes.

Description

technical field [0001] The invention relates to the technical field of interior decoration materials, in particular to a paper-faced gypsum board, its preparation method and its use method. Background technique [0002] Paper-faced gypsum board is a board made of board core and board paper. The board core is made of building gypsum as the main raw material and mixed with appropriate additives and fibers, and the board paper is used as the protective surface of the board core. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. With the development of the real estate industry, gypsum board has been widely used in my country, and its production, sales and application have increased year by year, from 200 million square meters in 2000 to 2.7 billion square meters in 2013. [0003] At present, for the perforated gypsum board that uses paper-faced gypsum board as the ba...
