Description
Technical Field
The invention belongs to the technical field of sectional materials for buildings, and particularly relates to a wood sectional material for a fireproof window and a manufacturing method thereof.
Background
Wood is a common building material, and because of its extremely low thermal conductivity, energy-saving doors and windows made of wood are widely popularized. In order to improve the fire resistance of wooden doors and windows, fire-retardant coatings are generally coated, and after long-time coating, the fire-retardant coatings covering the surfaces of wooden fire-retardant doors and windows are easy to crack, yellow and the like, and the feel and the appearance of the coatings are far inferior to those of coatings for wooden furniture. However, since the coating for wooden furniture is incompatible with the fire retardant coating, the coating for wooden furniture cannot be applied to the surface of the fire retardant coating, and there has never been known a product in which the coating for wooden furniture is applied to the surface of the fire retardant coating. Moreover, in the building design fire protection code GB 50016, a window is required to have at least a fire-resistant performance of more than 0.5 hour, and a fire-resistant window is locally required to be more than 1.5 hours. This is also a difficult indicator to achieve.
Meanwhile, the coating-type fireproof coating is generally required to be coated to a certain thickness, for example, in the technical Specification for fire protection of building steel structures, it is clearly required that the thickness of the thin fireproof coating which is resistant to fire for 0.5 hour is not less than 3mm, and the thickness of the fireproof coating which is resistant to fire for 1.5 hours is not less than 7mm. Because the fire-retardant coating is not a structural material, only the fire-retardant performance is considered, and the mechanical properties such as shearing resistance, tensile resistance and the like are not considered. According to the mechanics of materials, if a solid wood veneer is coated on the surface of a fireproof coating with the thickness of 3 mm-7 mm, the surface layer is stripped due to the insufficient shearing resistance of the fireproof coating.
The conventional organic halogen flame retardants do not have mechanical properties, and generate a large amount of smoke and toxic and corrosive gases during combustion. Meanwhile, the halogen compounds can generate chemical reaction with glue, so that various problems are caused, and the solid wood veneer can not be adhered and coated on the surface of the organic halogen flame retardant by the glue.
For this reason, this patent is filed.
