High-strength vertical-fiber waterproof rock wool plate and production method thereof

Abstract

The invention discloses a high-strength vertical-fiber waterproof rock wool plate and a production method thereof. The high-strength vertical-fiber waterproof rock wool plate has both sides to which inorganic fireproof waterproof films are combined. The inorganic fireproof waterproof films are combined to the vertical-fiber rock wool plate through quick instant glue. The inorganic fireproof films are fiberglass mats the surface of each of which is infiltrated with an inorganic silicon nano-material waterproof layer. By using the automatic line production manner, overcome are the defects that at present, existing various combined rock wool plates are generally high in production cost, a binding process is complex, steam-curing maintenance is required, thermal solidifying is required, a processing cycle is long and large-scale continuous production is unable to be achieved.

Description

technical field [0001] The invention relates to an external wall thermal insulation device in the construction field, in particular to a high-strength vertical thread waterproof rock wool board and a preparation method thereof. Background technique [0002] At present, the non-combustible thermal insulation materials in external wall insulation systems in China mainly use external wall thermal insulation rock wool boards for buildings, but they have many disadvantages: high water absorption rate, thermal insulation drawing strength and freeze-thaw performance drop sharply after water absorption, and the veneer layer is easy to Cracks fall off or even fall down as a whole; the organizational structure is loose, the tensile strength is low, the combination with the wall is not firm, the wind resistance is poor, and it is easy to fall off, endangering personal safety and increasing the cost of building maintenance; there are various types of reinforced rock wool boards , the ub...

Problems solved by technology

[0002] At present, the non-combustible thermal insulation materials in external wall insulation systems in China mainly use external wall thermal insulation rock wool boards for buildings, but they have many disadvantages: high water absorption rate, thermal insulation drawing strength and freeze-thaw performance drop sharply after water absorption, and the veneer layer is easy to Cracks fall off or even fall down as a whole; the organizational structure is loose, the tensile strength is low, the combination with the wall is not firm, the wind resistance is poor, and it is easy to fall off, endangering personal safety and increasing the cost of building maintenance; there are various types of reinforced rock wool boards , high production cost, complex bonding process, need steam curing maintenance, long heating and curing time, long processing cycle, unable to achieve large-scale production

Due to the above shortcomings, the wide application of external wall insulation rock wool board in the field of building external wall insulation is restricted.
