Abstract

The invention discloses a preparation method of door leaf plates made of eucalyptus wood cores. The method includes the following steps that eucalyptus wood filling plates and the eucalyptus wood cores are dried; the eucalyptus wood filling plates are cut into long strips, the long strips form frames shaped like a Chinese character 'ri (sun)' and are fixed, the frames are filled with square eucalyptus wood core bars, and door leaf plate models are obtained; adhesives are applied to density plates, then the density plates are bonded to two sides of each door leaf plate model, hot press-formingis performed, the door leaf plates made of the eucalyptus wood cores are prepared through edge sawing, and the like. According to the method, the eucalyptus wood cores are machined into the door leafplates, so that eucalyptus wood core resources can be utilized fully, the resource utilization rate can be increased, the procedures are simple, and the production cost can be reduced; and the used adhesives have the characteristics of high adhesion and good cold and water resistance. Used konjac gum, vinyl tri(methoxy propoxy) silane and acrylic resin can be subjected to the copolymerization reaction through di-isopropyl peroxydicarbonate, and the colloid property can be improved.

Description

technical field [0001] The invention belongs to the technical field of plate processing, and in particular relates to a preparation method of a eucalyptus core door leaf plate. Background technique [0002] Eucalyptus wood is generally processed by rotary cutting into veneers, which are used as core boards to produce plywood or laminated veneer lumber. After drying, the boards are bonded with adhesives to form multi-layer boards, which are often used in the production of furniture, office supplies, etc. . The wide application of eucalyptus has created a strong demand in the market, but more and more eucalyptus cores will be produced in the process of eucalyptus processing. At present, the utilization of eucalyptus cores is less, and they are often used as mop sticks, hoe handles or as firewood. Caused a great waste of resources. [0003] For this reason, through continuous research and development, the present inventors have prepared a method for preparing door leaf panels...
