Abstract

The invention discloses a mineral wool board and a preparation method thereof, and relates to the technical field of mineral wool boards. The mineral wool board is prepared from, by mass, 50-80 parts of granulated wool, 30-40 parts of emulsified wax, 20-30 parts of modified starch, 20-30 parts of plant fibers, 10-20 parts of thermal insulation granules, 10-20 parts of antibacterial agent, 2-8 parts of waste molecular sieve catalysts, 2-8 parts of functional additives and 50-90 parts of deionized water. The preparation method comprises the steps of (1) preparing the antibacterial agent; (2) preparing the thermal insulation granules; (3) conducting compounding; (4) conducting molding and drying; (5) conducting surface finishing. The mineral wool board has the properties of good sound absorption, heat insulation and preservation and mold prevention and moisture prevention, and is widely used in the fields of various build ceilings, interior decoration of wall adhesion and the like.

Description

technical field [0001] The invention relates to the technical field of mineral wool boards, in particular 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] Therefore, mineral wool board has strong applicability in the construction field. Mineral wool boards currently on the market have shortcomings such as easy agi...
