Abstract

The invention discloses a production method for a hydrophobic composite mineral wool board for a roof. The production method comprises the following steps of (1) preparing raw materials, namely mixing graystone, fly ash, gabbro, iron ore, bauxite and wollastonite, and melting the raw materials into a liquid mixture; (2) preparing hydrophobic liquid, namely uniformly mixing 0.3 to 0.5 weight percent of SILRES BS 1042, 5 to 8 weight percent of methylcellulose, 1 to 2 weight percent of polyacrylamide solution and the balance of phenolic resin phase; (3) preparing fibers, namely uniformly spraying the hydrophobic liquid onto mineral wool fibers; (4) preparing a fibrous body; (5) preparing a finished product, namely compounding a hard fireproof board on the upper layer of the fibrous body and compounding a dampproof aluminum foil veneer on the lower layer of the fibrous body.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a hydrophobic composite mineral rock wool board for roofing. Background technique [0002] At present, domestic standard buildings lack thermal insulation and fireproof materials with better performance, so fires occur frequently. The existing inorganic fiber cotton products belong to the flat fiber layered structure and cannot be directly used for external wall insulation: First, the fireproof basis of inorganic fiber The performance is very good, but the environmental protection performance and construction performance are very poor, and the fibers flying with the wind directly affect the health of the on-site personnel; secondly, its layered structure causes the mortar and cementitious materials applied on the surface of the product to only fix the surface layer, and the middle layer Will slowly sag over time, causing the insulation to form cavities, crack, and fall off.
