Inorganic vertical fibre composite thermal insulation board and manufacturing method thereof

Abstract

The invention relates to an inorganic vertical fibre composite thermal insulation board and a manufacturing method thereof. The manufacturing method mainly comprise the steps of: shearing an inorganic refractory fibre body into short fibre according to the producing requirement, arranging the short fibre vertically with a mold or a special tool and machine; heating and molding, spraying inorganic gelatinizer or interface agent on two surfaces of the inorganic vertical fibre body, then spraying or applying anti-crack mortar, and then pressing in alkali-proof glass fibre or wire mesh, finally painting gelatinizer complex membrane on the naked part of the vertical fibre. The glass fibre or wire mesh is a net structure consisting of multiple fibre yarns or iron wires which are distributed vertically and horizontally. The invention has the beneficial effects that the advantages of the inorganic fibre material are fully played, such as environmental protection, fire prevention, compression strength, negative wind pressure resistance, no loosing-off, no hanging-down, excellent construction performance and thermal insulating performance, easy factory production and the like; the state A-grade fire prevention requirement can be met; and the composite thermal insulation board can be used as the product integrate with environmental protection and energy conservation, fire prevention and thermal insulation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an inorganic standing fiber composite thermal insulation board and a manufacturing method thereof. 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 fo...
