Description

High-stability SPC aluminum-wood honeycomb composite board and preparation method thereof Technical Field The invention relates to the technical field of building decoration plates, furniture plates and vehicle and ship interior decoration plates, in particular to a multi-layer composite environment-friendly decoration plate taking aluminum honeycomb as a core layer, eucalyptus veneers as a structural reinforcing layer and SPC stone plastic materials as a surface protection layer and a preparation method thereof, which can be widely applied to various scenes such as home decoration, tooling, furniture manufacture, vehicle and ship interior decoration and the like, and is particularly suitable for environments with high requirements on plate stability, environmental protection, water resistance and fire resistance. Background With the rapid development of industries such as building decoration, furniture manufacturing, vehicle and ship interior decoration and the like, the comprehensive performance requirements of people on the decorative plates are increasingly severe, basic decoration functions are required to be met, and higher requirements are provided for the strength, structural stability, environmental protection, fire resistance, moisture resistance and suitability for applicable scenes of the plates. At present, the common decoration and structure boards on the market mainly comprise four major types of aluminum honeycomb boards, pure wood boards, single SPC stone plastic boards and conventional composite boards, but all the boards have obvious performance defects, and are difficult to meet the diversified requirements of the development of the modern industry. The traditional aluminum honeycomb panel is applied to partial tool scenes by virtue of the advantages of light weight and high strength, but the surface of the traditional aluminum honeycomb panel lacks of a wooden structure, so that the nail holding force is extremely poor, hardware cannot be directly installed, collapse and damage phenomena are easy to occur at the edge part, the traditional aluminum honeycomb panel is difficult to use as a core structural member such as a cabinet body and a door plate, and the application range of the traditional aluminum honeycomb panel is limited. The pure wood board has natural texture, meets aesthetic requirements of the masses on home decoration and furniture, but the characteristics of the wood material determine that the wood board is easy to be subjected to damp deformation, mildew and rot, has extremely poor fireproof performance, is extremely easy to damage in a humid environment or a high-temperature scene, has high environmental protection level greatly influenced by raw materials and processing technology, is difficult to realize stable control, is easy to cause formaldehyde exceeding and the like, and is harmful to human health. The single SPC stone plastic plate is used as a novel environment-friendly plate, has excellent waterproof, moistureproof, environment-friendly and flame-retardant properties, and long service life, but the plate is cool in texture, lacks the sense of temperature and humidity of natural materials, is insufficient in toughness and limited in structural strength, has a general sound and heat insulation effect, cannot meet the use requirement of high-end scenes, and is difficult to bear the structural support effect when being used alone. The conventional composite board is prepared by adopting a mode of simply superposing and compounding two layers or three layers, the interlayer bonding process is simple, the interlayer bonding force is weak, the problems of delamination, cracking and the like are very easy to occur when the composite board is used for a long time or the environment is changed, the production process is complex, the production cost is high, and the comprehensive cost performance is low. More importantly, an integrated composite board which can efficiently and stably combine the excellent nail holding power of the light high-strength eucalyptus veneer and the waterproof environment-friendly performance of the SPC stone plastic layer of the aluminum honeycomb core does not appear in the market at present, the existing boards all have performance short boards, and cannot simultaneously meet the comprehensive performance requirements of high strength, high stability, high nail holding power, water resistance, fire resistance, environment protection, no aldehyde and the like, and the use requirements of multiple scenes such as house-hold wallboards, high-end furniture cabinets, vehicle and ship interiors and the like are difficult to adapt. Therefore, the development of a novel composite board which has stable structure, difficult deformation, excellent nail holding force, water and moisture resistance, environmental protection, no aldehyde, fire resistance, flame retardance and wide application range becomes a technical problem to be solved in the field.
