Embodiment 1

[0047] Step 1: Weigh the adhesive 1 component and water preparation of bonding slurry, 100 parts by weight of phosphite, and 6 parts by weight of zeolite, 56 parts by weight of zeolite.

[0048] Step 2: Stirring the zeolite with water, fully dispersed, adding a phosphite, add heavycalcium powder, 980W fixed power ultrasound dispersion for 10 min, and mix evenly, the bond is obtained.

[0049] Step 3: Weighing the other components of the mineral wool plate, mineral cotton fiber: adhesive 1: Bond 2 Starch: Flocculant 1 Polyacrylamide: Flocculant 2 Sulfate: The weight ratio of emulsion paraffin is: 100: 28 : 5: 1.5: 1.2: 0.4.

[0050] Step 4: Flocculant 1 polyacrylamide is diluted to 15% mass concentration for water.

[0051] Step 5: The above-mentioned mineral fiber, binder 2 starch, flocculant 1 polyacrylamide aqueous solution, flocculant 2 sulfate, emulsified stone wax is sufficiently stirred in the stirrer, and then output to the retransmitter, mixed slurry The solid content is 4...

Embodiment 2

[0059] Example 2 is the same as that of the preparation method of Example 1. Different from the respective components of the bond 1 and water preparation bonding pulp, 100 parts by weight of phosphite, 10 parts by weight of heavier calcium, 4 weight Part, water 68 parts by weight.

[0060] Weighing mineral cotton fiber: adhesive 1: bonding 2 starch: flocculant 1 Polystyrene sulfonate: flocculant 2 sulfate: The weight ratio of emulsified paraffin is: 100: 20: 10: 2.5: 2 :2. Other preparation processes are equipped with Example 1, and the finished cotton panel finished product was prepared by 15 mm thickness.

Embodiment 3

[0062] Embodiment 3 is the same as that of the preparation method of Example 1. The difference is that the respective components of the adhesive 1 and the hydraulic binder pulp, 100 parts by weight of phosphite, and 20 parts by weight of the zeolite, 7 parts by weight of zeolite 82 parts by weight of water.

[0063] Weighing mineral cotton fiber: bonding 1: bonding 2 starch: flocculant 1 polyacrylamide: flocculant 2 sulfate: The weight ratio of emulsified paraffin is: 100: 25: 8: 2: 2.8: 1.5. Other preparation processes are equipped with Example 1, and the finished cotton panel finished product was prepared by 15 mm thickness.

Abstract

The invention discloses a mineral wool sound-absorbing board and a preparation method thereof. The formula composition of the mineral wool sound-absorbing board comprises 100-150 parts of mineral wool fiber, 1-20-28 parts of binder, 2 starch and 5 parts of binder by weight. -10 parts, 1.5-2.5 parts of flocculant 1, 1-3 parts of flocculant 2 and 0.4-2.0 parts of emulsified paraffin. The method comprises: weighing the binding material, mixing the binding material 1 evenly to make a binding slurry for use, and mixing the flocculant 1, mineral wool fiber, binding material 2 starch, flocculant 2 and the emulsified paraffin are fully stirred with water in the mixer to obtain a mixed slurry, and then the mixed slurry is shaped and dried to obtain a semi-finished mineral wool board wet board, and the bonding slurry is sprayed on the surface of the mineral wool board wet board, and after post-treatment to get the finished product. The mineral wool sound-absorbing board of the present invention uses phosphogypsum as a binding material to expand the application range of phosphogypsum, reduce the stacking of harmful substances, and play the role of resource recycling.

Description

Technical field [0001] The present invention relates to the field of building materials, and more particularly to a mineral wool sound absorbing plate and a preparation method thereof. Background technique [0002] The mineral wool sound absorbing plate is the main raw material with blast furnace slagmet, with starch as a major binder, add appropriate amount of adjuvant, additive, ingredient, molded, gelatinated dry, cut planing milling, finishing, spraying, packaging A high-grade ceiling decorative material such as a set of 10 maintenance, insulation, sound absorption, fire, decoration, etc. [0003] At present, during the production process of the mineral wool plate, the binder used is more embossed clay. With the continuous development of concave rod clay, the mineral resources are relatively short, the application level is constantly increasing, and its application has been developed in the direction of high value-added products, high-end products, resulting in restrictions i...
