Problems solved by technology

After a period of use, the catalytic ability of the discarded molecular sieve catalyst is reduced, but the main content has not changed much. Discarding these wastes rich in silicon and aluminum will not only cause environmental pollution but also waste resources.

Abstract

The invention provides a mineral wool board, and a preparation method thereof. The mineral wool board is prepared from, by weight, 80 to 100 parts of grain cotton, 10 to 35 parts of perlite, 10 to 20 parts of a waste molecular sieve catalyst, 10 to 15 parts of bentonite, 10 to 15 parts of plant fiber, 8 to 12 parts of starch, 3 to 5 parts of active carbon, 0.1 to 0.5 part of nano titanium dioxide, and 15 to 25 parts of water. According to the invention, solid wastes such as the waste molecular sieve catalyst and plant fiber are used, synergistic effects of different solid wastes are achieved fully, the building material according with the national standard is produced, comprehensive utilization of solid wastes is realized, environment pollution caused by discharge of solid wastes is reduced, no substance harmful to the environment is added, and no wastewater or waste residue is discharged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mineral wool board and a preparation method thereof. Background technique [0002] Mineral wool board is also commonly known as mineral wool sound-absorbing board. In the ceiling, we often use mineral wool board to effectively reduce indoor noise and ensure the comfort of the indoor environment. Mineral wool board is widely used in various tooling buildings due to its high-efficiency sound absorption, fire prevention, moisture resistance, and heat preservation. The surface design of common mineral wool boards has no directional pattern, which is very convenient for cutting. Compared with gypsum boards, the overall weight of mineral wool boards is lighter, which is more convenient for construction. [0003] Mineral wool is a floc of slag and organic matter that is melted at high temperature and thrown out by a high-speed centrifuge. It is harmless and pol...
