Medium density fiber board made from bamboo and wood

Abstract

The invention relates to a bamboo middle-density fiber plate, made from bamboo and Japanese cedar, wherein it is formed by 50-95 Japanese cedar sheets, 5-50 bamboo sheets, 8-15 urea-formaldehyde glue, 0.5-5 anti-fungus agent, 0.2-3 solidifier, and 1-3 ceresin wax. And its preparation comprises that: putting bamboo sheets into solution while NaOH is 1-5% of bamboo weight; at 80-130Deg. C and 0.5MPa pressure, boiling it for 10-15min, to be mixed with Japanese cedar sheets, to be grinded and dried; plating urea-formaldehyde glue added with anti-fungus agent, solidifier and wax emulsion on the fiber to be thermally compressed.

Description

Technical field: [0001] The invention relates to a medium-density fiberboard, in particular to a medium-density fiberboard made of miscellaneous bamboo and fast-growing wood as mixed raw materials. technical background: [0002] Fiberboard is a wooden board product made by sizing wood fibers and hot pressing, especially with a density of 0.45-0.88g / cm 3 Among them, medium density fiberboard (MDF) is widely used as a base material for furniture and flooring because of its low price and good performance. With the development of the national economy, it stimulates the continuous growth of the furniture and laminate flooring manufacturing industry, and the demand for MDF is also increasing. According to statistics, as of the end of 2003, there were 444 medium density fiberboard production lines in my country, and the actual annual output reached 10.4875 million m 3 . The manufacturing process of wooden MDF is a very mature and well-known technology, including peeling, slicing...

Problems solved by technology

CN 1484184A discloses a kind of laminate flooring with V-groove structure ( figure 1 ), because the wear-resistant paper and decorative paper impregnated with melamine-formaldehyde resin and pre-cured are brittle, according to its disclosed manufacturing method, the steel plate with V-shaped ribs is used to directly place the wear-resistant paper, decorative paper, MDF Pressing with balance paper will easily cause wear-resistant paper or decorative paper to be brittle, and the yield of the product is low

In actual production, although the MDF substrate is hot-pressed with a steel plate with V-shaped ribs first, and then the wear-resistant paper, decorative paper, MDF and balance paper are subjected to secondary hot-press composite molding, which can improve the yield, but not only Increases production costs, reduces production efficiency, and reduces mechanical properties due to repeated heating of the MDF substrate
