Embodiment 1

[0028] according to figure 1 The flowchart shown is for mineral wool board preparation.

[0029] Step 1: Weigh 100 parts by weight of granular cotton, 5.0 parts by weight of attapulgite clay, 5.0 parts by weight of modified starch, 0.1 part by weight of emulsified paraffin, 5 parts by weight of modified diatomite, 0.5 parts by weight of polyacrylamide, Al 2 (SO 4 ) 3 0.1 parts by weight.

[0030] Step 2: Mix the emulsified paraffin, modified diatomaceous earth and water well in advance.

[0031] Step 3: After fully stirring the above mixed material and the remaining ingredients with water in a mixer, output it to the feeding machine.

[0032] Step 4: The above-mentioned mixed slurry is wet-formed on a web forming machine, and cut into large boards by a cutting machine with high-pressure water.

[0033] Step 5: Transport the above-mentioned slabs to a drying kiln through a distributor, and dry them at 230-285°C for about 2 hours.

[0034] Step 6: After the slabs are out o...

Embodiment 2

[0038] In the present embodiment, each component is weighed according to the following proportions: Weigh 100 parts by weight of granular cotton, 25 parts by weight of attapulgite clay, 5.0 parts by weight of modified starch, 1.0 parts by weight of emulsified paraffin, and 20 parts by weight of modified diatomite Parts, polyacrylamide 2.0 parts by weight, Al 2 (SO 4 ) 3 1.0 parts by weight. The preparation process is the same as in Example 1, and a 12mm thick functional mineral wool board is obtained.

[0039] The waterproof performance of the functional mineral wool board is significantly improved. Compared with the traditional mineral wool board, the short-term water absorption rate is reduced by 5%, and the bulk density is reduced by more than 10%. After 24 hours of fluorescent lamp irradiation, the removal rate of formaldehyde can reach more than 80%. The indoor humidity can be stabilized at 40%-50% at room temperature.

Embodiment 3

[0041] In this example, weigh each component according to the following proportions: weigh 100 parts by weight of granular cotton, 10 parts by weight of attapulgite clay, 10 parts by weight of modified starch, 0.5 parts by weight of emulsified paraffin, and 1.0 parts by weight of polyacrylamide, Al 2 (SO 4 ) 3 0.5 parts by weight, and 10 parts by weight of modified diatomaceous earth. The preparation process is the same as in Example 1, and a 12mm thick functional mineral wool board is obtained.

[0042] Compared with the traditional mineral wool board, the short-term water absorption rate of the prepared functional mineral wool board is reduced by 2%, the bulk density is reduced by more than 5%, and it has the characteristics of breathing and humidity control, air purification, antibacterial and deodorization.

Abstract

The invention discloses an environment-friendly mineral wool board with functions of humidity adjustment and air purification, which comprises the following components in parts by weight: 100 parts of granulated wool, 5 to 25 parts of attapulgite, 1 to 10 parts of modified starch, 0.1 to 1.0 part of emulsified paraffin, 5 to 20 parts of modified diatomite, 0.5 to 2.0 parts of polyacrylamide and 0.1 to 1.0 part of Al2(SO4)3. The invention also discloses a production method for the environment-friendly mineral wool board with the functions of humidity adjustment and air purification, which comprises the following steps of: weighing all the components according to the proportion; fully mixing the modified diatomite and water, adding the emulsified paraffin, and continuously stirring; fully stirring the mixed material and the remaining ingredients in a stirrer with water, and then performing beat-molding by a wet method; and performing drying and surface finish machining to obtain a finished product. According to the functional mineral wool board, the modified diatomite can effectively adsorb the emulsified paraffin so that the mineral wool board has enhanced waterproof performance and better functions of degrading harmful substances and adjusting humidity.

Description

technical field [0001] The invention relates to a mineral wool board and a preparation method thereof, in particular to an environmentally friendly mineral wool board with the functions of humidity adjustment and air purification and a preparation method thereof. Background technique [0002] Mineral wool board is a new type of building material. Because of its excellent fireproof, waterproof, moisture-proof, sound insulation, heat insulation, and easy deep processing, it is widely used in the decorative ceiling of public buildings at home and abroad, and can also be used in industrial plants. , senior residences and high-rise buildings. [0003] Wet fourdrinier sheeting is the main forming method for the production of mineral wool sound-absorbing panels today, with fast sheeting speed and high production efficiency. However, part of the admixture will be lost during molding, which will increase the consumption quota of the admixture. [0004] With the continuous improveme...
