Description

A kind of recombinant decorative material Recombinant Wood
Technical field
The present invention relates to a kind of Furniture panel, particularly relate to a kind of recombinant decorative material Recombinant Wood.
Background technology
Along with the problem of global warming highlights day by day, exceedingly odious weather takes place frequently, and the low-carbon economy be the theme with " low emission, low stain, less energy-consumption " is more and more approved by people and praised highly.Under such background condition, wooden industry utilizes the characteristic of its inherent " green ", " environmental protection ", " cleaning ", in development low-carbon economy, reply climate change, is just playing the effect become more and more important.Timber and woodwork have well carbon effect admittedly.As long as without putrefaction, not burn, what the solid carbon function of timber and woodwork will be long-term, stable continues.Some solid carbon time can reach decades, centuries.Therefore, increase timber and use, and the work-ing life of try one's best prolonging wood and woodwork, reduce discharging significant to reduction energy consumption, increase.According to measuring and calculating, forest often produces 1 ton of timber, on average can stabilizing carbon dioxide 1470kg, releasing oxygen 1070kg.
Timber is unique reproducible natural resource in four large material of construction.The World Forests continues to reduce, and add up world forest resources according to Food and Argriculture OrganizationFAO, within 2010, the World Forests area is about 4,000,000,000 hm2, and the assessment result of nineteen ninety about 40.8 hundred million hm2.From year change, within 1990 ~ 2010 years, the World Forests area amounts to annual about minimizing 4,000,000 hm2.Protection wildwood; cultivate artificial fastgrowing trees, be the best measure of maintaining ecological balance, and meet the demand of people to timber; world wide environment sfgd. gets more and more, and the relation coordinated between Economic development and environment protection becomes the main themes that various countries pay close attention to.
Along with the minimizing day by day of the forest reserves, the application quantity of artificial fast growing wood is increasing, and along with the minimizing day by day of natural rare tree timber, by carrying out deep processing to fast growing wood, it is made to possess the feature of rare tree, thus substitute it, reduce the consumption of rare tree timber, become the new problem of wood-processing industry Sustainable development.Recombinant decorative material (industry is commonly called as " Recombinant Wood ") is exactly one of important achievement of this new problem.Recombinant Wood take artificial fast growing wood as raw material, in its manufacturing processed, do not destroy microtexture and the build-in attribute of timber, remain that natural timber is heat insulation completely, natural attribute that insulation, temperature adjustment, damping etc. are all, overcome the numerous natural defect of artificial fast growing wood, the high-value-use of timber can be realized, lead the technological innovation of industry to reach the Sustainable development of industry.
Recombinant decorative material originates from Britain, the Italy of the thirties in 20th century the earliest, mainly utilizes log directly to develop slicing veneer.The sixties, Italy and Britain have researched and developed with common seeds rotary cut venner for raw material in succession, and through veneer bleaching, dyeing, make flitch by wet sticky the colding pressing of certain way rift grain assembly, slicing obtains artificial veneer.At the beginning of the seventies, the companies such as Italian Alpi, IPir and PANASONIC electrician achieve the suitability for industrialized production of Recombinant Wood, and are provided with the research and development centre of Recombinant Wood, specialize in the research and development of Recombinant Wood production technology.At the beginning of the eighties, China starts to enter Recombinant Wood industry.Nearly 30 years, Italy and Japan mainly carried out large quantifier elimination and industrialization development around the manufacturing equipment of Recombinant Wood and the functionalization of product.Recombinant Wood is extended to Recombinant Wood sawn timber, composite floor board, PLASTIC LAMINATED, outdoor timber structure goods, until various artwork, daily necessities and stationery sports goods from decorative veneer single at first.Recombinant Wood, as the reproducible Novel environment-friendlymaterial material of one, has penetrated into the every field of people's life.
The research and development of China to recombinant decorative material start from the eighties in 20th century.At the beginning of 1980, Wei De group starts the research and development carrying out Recombinant Wood, Shanghai Inst. of Wood Industry and the radial texture artificial veneer of the imitative redwood of Shanghai Study of Furniture Suo Deng unit trial-production, manufacture experimently again the artificial veneer of tangential texture and the dyeing of special-shaped texture for 1987, and put on market with short run.1988, the clammy glue laminated flitch of the Chinese Academy of Forestry's timber industry Research Institute.The joint research such as Nanjing Forestry University, Chinese forest-science academy artificial decoration veneer production technology in 1996, has manufactured experimently the artificial veneer of different texture, different colours.
Current, functionalization is the development important directions of recombinant decorative material.CN103171014B (2015-4-15) discloses a kind of preparation method of Recombinant Wood, but this Recombinant Wood burst size of methanal is higher, the infiltration of staining reagents difficulty, easily run off, not weather-proof, with aqueous adhesive poor compatibility, bleaching and dyeing process environment and pollute more serious; Because of color development and the colored single palte interface gummed of fire retardant severe jamming staining agent, this Recombinant Wood does not do fire-retardant finish, and its functional needing is improved.
