Scrimber and preparation method thereof

Abstract

The invention relates to scrimber and a preparation method thereof. According to the scrimber, logs and brush wood with a small diameter are taken as woody raw materials, the woody raw materials are cut off, soaked and ground to form wood bunches which are not broken in the longitudinal direction or loose in the transverse direction and are connected in a staggered manner, the wood bunches are separated, dried, glued, assembled, paved and hot-pressed through turning, pressing and twisting, and the scrimber is prepared. The scrimber has the main performance as follows: the thickness ranges from 15 mm to 25 mm, the density ranges from 1.1 g / cm<3>-1.2 g / cm<3>, the internal bond strength ranges from 4 MPa to 5 MPa, the static bending intensity ranges from 120 MPa to 130 MPa, the thickness swelling rate of the scrimber after water absorption is 4%-5%, and the formaldehyde emission ranges from 1.2 mg / L to 1.4 mg / L. The scrimber and the preparation method have the advantages that the scrimber product prepared with the simple and efficiency process has better mechanical strength and size stability and is suitable for large-scale production, the economic benefits are high, the utilization efficiency and the economic value of wood are improved, and convenience is provided for production, utilization and popularization of the scrimber.

Description

【Technical field】

[0001] The invention relates to the field of wood-based panels, in particular to a recombined wood and a preparation method thereof. 【Background technique】

[0002] With the rapid development of social economy and the improvement of people's living standards, people's demand for furniture and other indoor and outdoor decoration materials is also increasing. However, due to the unrestrained use and consumption of natural resources by humans, timber resources are increasingly scarce. The manufacture of particleboard, fiberboard and other wood-based panels all disrupt the natural arrangement of wood fibers, of course the performance is destroyed, and then they are rearranged and glued together with great effort. In order to make full and reasonable use of the original characteristics of wood raw materials, it is envisaged to design and develop a product similar to natural wood—recombined wood—under the condition of not disturbing the original wood fiber arran...
