Production method for anti-deformation material-saving paint-free three-laminated composite plate

Abstract

The invention relates to a production method of an anti-deformation material-saving paint-free three-laminated composite plate. A panel and a baseplate are melamine-impregnated laminated plates, and the middle plate is a lateral assembly finger-jointed fir plate. The production method includes slicing the middle plate in to stripes, extracting material of the middle plate, processing rough blanks of the middle plate, finger-jointing the middle plate, hot- pressing the middle plate, repairing the middle plate, compositely pressing the entire plate and post-processing the entire plate. Since special processing is adopted, wasted small or short fir material which is lower than 0.65 cm in thickness, 2cm in length and 1.5 cm in width can be utilized, waste of edge material can be controlled effectively, a four-side moulding procedure can be omitted during processing the rough blanks of the middle plate after the fir material is dried, mortising and finger jointing can be performed directly, energy consumption is lowered by 12%, utilizing rate of fir with diameter ranging from 8 to 10 cm is increased by more than 15% after being processed into three-laminated finger-jointed plates by calculating, and the rate of non-section plate material is increased by more than 30%.

Description

technical field [0001] The invention relates to the technical field of fir boards and processing thereof, in particular to a production method of a three-layer fir composite board with anti-deformation, material saving and paint-free. Background technique [0002] The production of fir finger-jointed boards in my country started in the 1980s. Finger-joints can make short materials long-term, small materials can be used in large quantities, and inferior materials can be used in high-quality ones. Areas where high-quality wood resources are scarce have a great role, suitable for mechanical processing, less equipment investment, obvious economic benefits, and great development potential. The rate is not high, especially the side boards have edges, skins, short materials, etc., which cannot be used, and the boards are easy to be deformed in arc shape, and the current fir blockboards need to be painted, which is easy to pollute the environment.
