Abstract

The invention discloses a bamboo reinforced crop straw fiber-based fireproof door material. The bamboo reinforced crop straw fiber-based fireproof door material is a composite material using crop straw fibers as a base material and bamboos as a reinforcing material. A preparation method of the bamboo reinforced crop straw fiber-based fireproof door material disclosed by the invention comprises the following steps of: uniformly mixing the crop straw fibers with a fireproof inorganic adhesive so as to obtain a mixture; paving the mixture and the bamboos so as to obtain fireproof material plate blank using the crop straw fibers as the base material and the bamboos as the reinforcing material; sending the fireproof material plate blank into a hot press, and performing hot press molding; performing maintenance; performing drying; performing edging; and performing sanding so as to obtain the fireproof door material. According to the bamboo reinforced crop straw fiber-based fireproof door material disclosed by the invention, the bamboos are arranged at certain intervals in an interlayer, so that the density of the crop straw fireproof material is reduced, the bending strength and the tensile strength of the crop straw fireproof material can also be improved, and the longitudinal thickness swelling rate after water absorption is reduced.

Description

technical field [0001] The invention belongs to the field of plant-based fire door material manufacturing, and in particular relates to a raw bamboo-reinforced crop straw fiber-based fire door material and a preparation method thereof. Background technique [0002] my country produces more than 1 billion tons of usable crop straw resources every year, a considerable part of which is incinerated, resulting in waste of resources and serious pollution of the environment. Crop straw can be used to make straw-based inorganic composite materials for lightweight fire doors. However, straw fiber-based inorganic composite materials made of crop straws have high density and longitudinal water expansion rate, low static bending strength and elastic modulus, and are easy to deform, which limits their application fields. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a raw bamboo reinforced crop straw fiber-based fire door ...
