Abstract

The invention discloses a high-strength flame-retardant heat-insulation composite door and window, and relates to the field of composite doors and windows. The high-strength flame-retardant heat-insulation composite door and window is prepared by uniformly mixing a wood-ceramic composite material with aerogel fibrofelt and then carrying out hot press molding, wherein the aerogel fibrofelt accountsfor 1.5%-3.6% of the mass of the wood-ceramic composite material, and the wood-ceramic composite material is composed of a wood-plastic composite material, low-melting-point glass powder, a dispersing agent, a binder and a defoaming agent. By adding the low-melting-point glass powder, the mechanical strength of the composite door and window is greatly improved, so that the composite door and window has excellent flame retardant property; and by introducing the aerogel fibrofelt, the composite door and window has the advantages of fire resistance, flame retardance, sound insulation and shock absorption, and can meet the high requirements of people on modern buildings.

Description

technical field [0001] The invention belongs to the technical field of composite doors and windows, and in particular relates to a high-strength flame-retardant and heat-insulating composite door and window. Background technique [0002] The area of ​​newly built residential houses in our country is close to 3 billion square meters every year. Doors and windows are an important part of modern buildings. Calculated according to the ratio of building area to door and window area of ​​8:1, the replacement of old doors and windows is not included every year. New houses only have doors and windows. The amount used is 375 million square meters, so the amount of door and window materials is very alarming, and the requirements for energy saving and environmental protection of doors and windows are getting higher and higher. Up to now, doors and windows have experienced four eras of wood, steel, aluminum alloy, and plastic steel doors and windows. Wooden doors and windows are modera...
