Method for preparing staggered laminated integrated prefabricated wallboard

Abstract

The invention discloses a method for preparing a staggered laminated integrated prefabricated wallboard. Firstly, at least two layers of bamboo and wood laminates are impregnated with a flame retardant, and are superposed, a grid composite layer and a thermal insulation material are added and filled between the plurality of adjacent laminates, a wallboard can be prepared by holding the pressure for 12 to 24 hours under the condition of 0.5 to 1.5 MPa, and sound absorbing holes can be opened on the surface of the prepared wallboard to obtain the staggered laminated integrated prefabricated wallboard. The staggered laminated integrated prefabricated wallboard has the significant advantages that the bamboo and wood laminates are arranged in a crisscross manner, and combined with the grid composite layer, by cold-pressing curing, the prepared prefabricated wallboard has good weather resistance, and the longitudinal and lateral strength and rigidity are improved; in the preparation, the bamboo and wood laminates are impregnated with a flame retardant, and filled with a thermal insulation material, and the sound-absorbing holes are formed on the surface of the wallboard, so that multifunctional integrated standard prefabrication of the wallboard can be realized, the wallboard can absorb sounds and insulate sounds, and is also fireproof, fire-resistant, and thermal-insulating.

Description

technical field [0001] The invention belongs to the field of prefabricated wallboards, in particular to a method for preparing cross-laminated integrated prefabricated wallboards. Background technique [0002] Along with worldwide forest resource reduction, people begin to study the bamboo-wood composite material work that is main raw material with bamboo and artificial forest timber. The composite of wood and bamboo can rationally exert the excellent characteristics of bamboo and wood, and obtain the double effect of saving wood resources and ensuring the strength and appearance quality of the material. Compared with pure bamboo wood-based panels, wood-bamboo composite materials are more designable in structure and performance. From the perspective of bamboo utilization, the former is also more superior than the latter. Therefore, as engineering structural materials, wood and bamboo aggregation materials have broad prospects, and also open up new ways for the industrial ut...

Problems solved by technology

[0007] The integrated prefabricated wallboard prepared by the present invention has two-way stress in the vertical and horizontal directions, not only has good mechanical and weather resistance properties, but also has high strength and rigidity, and has improved the problems of bamboo anisotropy, uneven stress and large creep; At the same time, several grid composite layers are used, and the combination of grid composite layers and bamboo wood laminates further enhances the force in the horizontal and vertical directions of the component, effectively improves the strength and stiffness of the structure in both directions, and integrates decoration during preparation. , from the installation of components to heat preservation, sound insulation, fire prevention treatment and post-decoration are all completed in the factory, which can avoid high-altitude operations, save costs, and help improve construction quality and efficiency
