Description
Technical field
The present invention relates to a kind of sheet material, especially a kind of functional type facing oriented wood chipboard.
Background technology
Along with the problem of global warming highlights day by day, exceedingly odious weather takes place frequently, and is increasingly approved by people with the low-carbon economy that " low emission, low stain, low energy consumption " is the theme and praises highly.Under such background condition, wood 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 good carbon sequestration effect.As long as without putrefaction, not burning, what the carbon sequestration function of timber and woodwork will be long-term, stable continues.Some carbon sequestration time is up to decades, centuries.Therefore, increase timber and use, and the service life of try one's best prolonging wood and woodwork, reduction energy consumption, increase are reduced discharging significant.According to measuring and calculating, forest often produces 1 ton of timber, on average can fix carbon dioxide 1470kg, releasing oxygen 1070kg.
Timber is unique reproducible natural resources in four big construction materials.The World Forests continues to reduce, and according to FAO (Food and Agriculture Organization of the United Nation), world forest resources is added up, and the World Forests area in 2010 is about 4,000,000,000 hm2, and the assessment result of nineteen ninety about 40.8 hundred million hm2.Changing from year, within 1990～2010 years, the World Forests area amounts to annual about minimizing 4,000,000 hm2.Protection wildwood; cultivate artificial fast-growing woods, be the best measure of maintaining ecological balance, and meet people's demand to timber; world wide environment protective measure gets more and more, and coordinates the relation between economic development and environmental conservation and becomes the main themes that various countries pay close attention to.
Minimizing day by day along with 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 fast growing wood is carried out deep processing, it is made to possess the feature of rare tree, thus instead of, reduce the consumption of rare tree timber, it has also 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 is with artificial fast growing wood for raw material, in its manufacture process, do not destroy microstructure and the build-in attribute of timber, the all of natural attributes such as natural timber heat insulation, insulation, homoiothermic, damping has been fully retained, 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 the Britain of the thirties in 20th century, Italy the earliest, directly develops slicing veneer mainly by log.The sixties, Italy and Britain have researched and developed with common seeds rotary cut venner for raw material in succession, through veneer bleaching, dyeing, make flitch by wet viscous the colding pressing of certain way rift grain assembly, and slicing prepares artificial veneer.At the beginning of the seventies, the company such as Alpi, IPir and PANASONIC electrician of Italy achieves the industrialized production of Recombinant Wood, and is provided with the research and development centre of Recombinant Wood, specializes in the research and development of Recombinant Wood production Technology.At the beginning of the eighties, China initially enters Recombinant Wood industry.Nearly 30 years, Italy and Japan carried out substantial amounts of research and industrialization development mainly around the manufacture 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 from decorative veneer single at first, until various artware, the articles for daily use and stationery sports goods.Recombinant Wood, as a kind of reproducible Novel environment-friendlymaterial material, has penetrated into the every field of people's life.
The research and development of recombinant decorative material are started from the eighties in 20th century by China.At the beginning of 1980, Wei De group proceeds by the research and development of Recombinant Wood, the unit trial-production imitative redwood radially texture artificial veneers such as Shanghai Inst. of Wood Industry and Shanghai Study of Furniture institute, manufacture experimently again tangential texture and the artificial veneer of special-shaped texture dyeing for 1987, and put on market with small lot.1988, the clammy glue laminated flitch of the Chinese Academy of Forestry's timber industry Research Institute.The joint research artificial decoration veneer production technologies such as Nanjing Forestry University, forest-science academies of China in 1996, have manufactured experimently the artificial veneer of different texture, different colours.
Currently, functionalization is the development important directions of recombinant decorative material.The preparation method that CN103171014B (2015-4-15) discloses a kind of Recombinant Wood, but this Recombinant Wood burst size of methanal is higher, staining reagents difficulty permeates, is easy to run off, not weather-proof and aqueous adhesive poor compatibility, bleaching and dyeing process environment and pollute more serious；Because color development and the colored single palte interface of fire retardant severe jamming stain are glued, this Recombinant Wood does not do flame treatment, and its functional needing is improved.
