Abstract

The invention discloses a directional rock wool board having a three-dimensional structure and a manufacturing method thereof and belongs to the field of building materials. The rock wool board is made from the following raw materials in parts by weight: 40-50 parts of iron ore, 10-20 parts of natural pyrrhotite, 10-20 parts of coke, 10-15 parts of mineral waste residues, 5-8 parts of a water repellent, 4-6 parts of urea, 8-10 parts of phenolic resin and 3-5 parts of vinyl tris(t-butylperoxy)silane. Creases are formed in the thickness direction of the rock wool board, overlap joint is formed among different layers of creases, and accordingly, a stereoscopic crossed three-dimensional structure is formed, so that the stripping resistance of the rock wool board is greatly enhanced. The rock wool board has reasonable density gradient, the diameters of fibers form gradient variation, and the rock wool board is separated into more spaces by reasonable density gradient and fiber diameter variation, so that the rock wool board is ensured to have low heat conductivity and can have a better heat insulating effect.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically relates to a three-dimensional structure oriented rock wool board and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's national economy, architectural styles and types emerge in endlessly, and the requirements for the application of building energy-saving materials and fire safety protection are also getting higher and higher. Among them, the rock wool board for construction is specially designed and produced for the thin plastering system of external wall insulation of buildings, and is suitable for external wall insulation or energy saving of newly built or existing buildings with dense structures such as concrete or brick walls. Retrofit; the external wall thermal insulation rock wool belt can also be used as a fire isolation belt, and it is used in conjunction with thermal insulation materials whose combustion perf...
