Embodiment 1

[0022] according to figure 1 The flow chart shown is for the preparation of environmentally friendly mineral wool boards.

[0023] Step 1: weigh 5 parts by weight of modified starch, 20 parts by weight of attapulgite clay, and 10 parts by weight of bamboo charcoal, and stir evenly;

[0024] Step 2: Weigh Nano TiO 2 15 parts by weight, 10 parts by weight of cuprous oxide, stirred evenly;

[0025] Step 3: Weigh 100 parts by weight of granular cotton, 1.0 parts by weight of polyacrylamide, Al 2 (SO 4 ) 3 0.5 parts by weight, stirred with the two homogeneous mixtures obtained in steps 1 and 2 for 4 minutes until uniform;

[0026] Step 4: Stir the solid homogeneous mixture in step 3 with water evenly, and adjust the solid content of the mixed slurry to be 4%;

[0027] Step 5: The above-mentioned mixed slurry is taken into shape by wet method, and cut into large boards;

[0028] Step 6: Transport the above-mentioned slabs to a drying kiln, and dry them at 260° C. for 1.5 hour...

Embodiment 2

[0031] The difference from Example 1 is that the addition amount of each raw material component and the temperature and time of drying are different, and the addition amount and drying temperature are as follows respectively:

[0032] 100 parts by weight of granular cotton;

[0033] 10 parts by weight of modified starch;

[0034] Attapulgite clay 30 parts by weight;

[0035] 25 parts by weight of bamboo charcoal;

[0036] Nano-TiO 2 20 parts by weight;

[0037] 20 parts by weight of cuprous oxide;

[0038] 2.5 parts by weight of polyacrylamide;

[0039] al 2 (SO4) 3 1.5 parts by weight;

[0040] Dry the plate at 285°C for 1 hour;

[0041] Tests have shown that the environmentally friendly mineral wool board of this embodiment, compared with the traditional mineral wool board, has a formaldehyde removal rate of more than 90% after being irradiated by fluorescent lamps for 24 hours; the loss of binder is reduced, and the loss is reduced by 65% ​​compared with the tradit...

Embodiment 3

[0043] The difference from Example 1 is that the addition amount of each raw material component and the temperature and time of drying are different, and the addition amount and drying temperature are as follows respectively:

[0044] 100 parts by weight of granular cotton;

[0045] 1 part by weight of modified starch;

[0046] 5 parts by weight of attapulgite clay;

[0047] 5 parts by weight of bamboo charcoal;

[0048] Nano-TiO 2 5 parts by weight;

[0049] 0.5 parts by weight of polyacrylamide;

[0050] al 2 (SO4) 3 0.1 parts by weight;

[0051] Dry the plate at 230°C for 2 hours;

[0052] Tests have shown that the environmentally friendly mineral wool board of this embodiment, compared with the traditional mineral wool board, has a formaldehyde removal rate of more than 70% after being irradiated by fluorescent lamps for 24 hours; the loss of binder is reduced, and the loss is reduced by 25% compared with the traditional process .

Abstract

The invention discloses an eco-friendly mineral wool board. The eco-friendly mineral wool board comprises, by weight, 100 parts of granulated wool, 1-10 parts of modified starch, 5-30 parts of attapulgite clay, 5-25 parts of bamboo charcoal, 5-20 parts of nano-TiO2, 0-20 parts of cuprous oxide, 0.5-2.5 parts of polyacrylamide and 0.1-1.5 parts of Al2(SO4)3. The eco-friendly mineral wool board has highly efficient adsorptive performances of bamboo charcoal, reduces a binder loss, utilizes cuprous oxide and TiO2 photocatalytic air purification materials and can fast and stably purify air for a long time.

Description

technical field [0001] The application relates to an environmentally friendly mineral wool board and a preparation method thereof, in particular to an environmentally friendly mineral wool board with multiple functions such as absorbing indoor harmful substances, purifying indoor air, and releasing negative ions, and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living conditions, people spend 80% to 90% of their time indoors in a day, and the quality of indoor air directly affects people's physical and mental health. Especially the harmful gases produced by new house decoration and new furniture, such as formaldehyde, volatile organic compounds (VOC), semi-volatile organic compounds (SVOC), etc., seriously pollute the indoor air, so improving the indoor living environment is a Problems to be solved. [0003] Mineral wool board is a new type of building material. It is widely used in the decorative cei...
