Lightweight composite flame-retardant paper honeycomb insulation roof panel in cold region

Abstract

The invention discloses a lightweight composite flame-retardant paper honeycomb insulation roof panel in a cold region. The lightweight composite flame-retardant paper honeycomb insulation roof panel in the cold region comprises an inner core material, and an outer surface layer, wherein the inner core material comprises a waterproof rock wool insulation board and flame-retardant paper honeycomb plates which are laminated below the waterproof rock wool insulation board; the outer surface layer is coated outside the inner core material; a waterproof paint is arranged between the outer surface layer (of which the inner side is coated with the waterproof paint) and the inner core material. According to the lightweight composite flame-retardant paper honeycomb insulation roof panel, the construction cost is reduced; the environmental requirements are met; and light weight, waterproofness, heat retaining property and ageing resistance are achieved. The fire resistance of the insulation roof panel achieves the Al level of noninflammability; the waterproofing grade is II level; the heat transfer coefficient is 0.372-0.426 (W / m<2>.K), and lower than the requirements of the heat transfer coefficients of residential architectures and public buildings in the cold region, which are specified in China. The lightweight composite flame-retardant paper honeycomb insulation roof panel is suitable for inaccessible roofs of non-high-rise civil buildings and light industrial buildings in the cold region.

Description

technical field [0001] The invention relates to a light-duty composite flame-retardant paper honeycomb thermal insulation roof panel in cold regions, in particular suitable for unmanned roofs of non-high-rise civil buildings and light industrial workshops in cold regions. Background technique [0002] In the prior art, steel-frame light-duty energy-saving composite roof panels use cold-formed thin-walled steel as the outer frame; reinforced grid or reinforced concrete as auxiliary ribs; and high-performance ultra-light foamed cement or other heat-insulating materials as core materials; It is a new type of roofing material composed of alkali-resistant glass fiber mesh cloth reinforced polymer cement mortar as the upper and lower layers. However, its self-weight is relatively large, and the reinforced grid or reinforced concrete is used as auxiliary ribs to make the structure more complicated, and the deformation of different materials is inconsistent, resulting in hidden dang...
