Description
Technical field
The present invention relates to a kind of Furniture panel more particularly to a kind of recombinant decorative material Recombinant Woods.
Background technology
The problem of with global warming, is increasingly prominent, and exceedingly odious weather takes place frequently, with " low emission, low stain, low energy
The low-carbon economy that consumption " is the theme increasingly is approved and is praised highly by people.Under such background condition, wood industry is all with life using it
Come " green ", " environmental protection ", " cleaning " characteristic, develop low-carbon economy, cope with climate change in, just playing and becoming more and more important
Effect.Timber and woodwork have good carbon sequestration effect.As long as without putrefaction is not burnt, the carbon sequestration function of timber and woodwork
Will for a long time, stablize continue.Some carbon sequestration times are up to decades, centuries.Therefore, increase timber to use, and to the greatest extent
The service life of prolonging wood and woodwork is measured, is of great significance to reducing energy consumption, increasing emission reduction.According to measuring and calculating, forest often gives birth to
1 ton of timber is produced, can averagely fix carbon dioxide 1470kg, release oxygen 1070kg.
Timber is unique reproducible natural resources in four big construction materials.The World Forests are persistently reduced, according to the United Nations's grain
Agriculture tissue counts world forest resources, and the World Forests area is about 4,000,000,000 hm2 within 2010, and the assessment result of nineteen ninety is about
40.8 hundred million hm2.Change from year, 1990~2010 years the World Forests areas amount to 4,000,000 hm2 of annual about reduction.Protection is natural
Woods cultivates artificial fast-growing woods, is the best measure of maintaining ecological balance, and meet the needs of people are to timber, world wide
Interior environmental protective measure is more and more, and coordinating the relationship between economic development and environmental protection becomes the main view of various countries' concern
Topic.
With the increasingly reduction of the forest reserves, the application amount of artificial fast growing wood is increasing, and with natural rare tree
The increasingly reduction of timber by carrying out deep processing to fast growing wood, makes it have the feature of rare tree, so as to instead, reduce
The consumption of rare tree timber, it has also become the new issue of wood-processing industry sustainable development.Recombinant decorative material（Industry is commonly called as " section
Skill wood "）It is exactly one of important achievement of this new issue.Recombinant Wood be using artificial fast growing wood as raw material, in its manufacturing process,
The microstructure and build-in attribute of timber are not destroyed, it is all that heat-insulated natural timber, insulation, temperature adjustment, damping etc. has been fully retained
Natural attribute, overcome the numerous natural defects of artificial fast growing wood, it can be achieved that the high-value-use of timber, leads the technology of industry to create
The new sustainable development for reaching industry.
Recombinant decorative material originates from Britain, the Italy of the 1930s earliest, is mainly directly developed using log
Go out slicing veneer.The sixties, Italy and Britain have been researched and developed in succession using common seeds rotary cut venner as raw material, by veneer
Flitch is made by the wet viscous cold pressing of certain way rift grain assembly in bleaching, dyeing, and artificial veneer is made in slicing.The beginning of the seventies, Italy
The companies such as Alpi, IPir and Panasonic Japan electrician realize the industrialized production of Recombinant Wood, and the research and development equipped with Recombinant Wood
The research and development of Recombinant Wood production Technology are specialized at center.The beginning of the eighties, China initially enter Recombinant Wood industry.Closely
30 years, Italy and Japan carried out a large amount of research and production mainly around the manufacturing equipment of Recombinant Wood and the functionalization of product
Industry melts hair.Recombinant Wood is extended to Recombinant Wood sawn timber, composite floor board, fire-proof plate, outdoor wood knot from initially single decorative veneer
Structure product, until various craftworks, daily necessities and stationery sports goods.Recombinant Wood as a kind of reproducible Novel environment-friendlymaterial material,
The every field of people's life is penetrated into.
China starts from the 1980s to the research and development of recombinant decorative material.At the beginning of 1980, Wei De groups proceed by science and technology
The research and development of wood, the imitative redwood radial direction texture of the units trial-production such as Shanghai Inst. of Wood Industry and Shanghai Study of Furniture institute are artificial
Veneer is manufactured experimently tangential texture and the artificial veneer of special-shaped texture dyeing for 1987, and is launched with small lot again.1988,
The clammy glue laminated flitch of the Chinese Academy of Forestry's timber industry Research Institute.Nanjing Forestry University in 1996, Chinese forest-science academy
Deng common research artificial decoration veneer production technology, manufactured experimently different texture, different colours artificial veneer.
Currently, functionalization is the development important directions of recombinant decorative material.CN103171014B (2015-4-15) is disclosed
A kind of preparation method of Recombinant Wood, however the Recombinant Wood burst size of methanal is higher, staining reagents difficulty permeates, is easy to run off, is not weather-proof,
