Description
Technical field
The present invention relates to field of plate manufacture, particularly a kind of electrostatic fiber sizing plate manufacturing process.
Background technology
Timber is environmentally friendly ecomaterial that is renewable, that recycle, is widely used in the industries such as furniture, floor, construction and decoration.Artificial forest is the main raw material(s) woods of world's forest chemical, and China artificial forest has reached more than 5,300 ten thousand hectares, ranks first in the world.Wood-based plate is the main path that artificial forest wood high-quality and high-efficiency utilizes, and within 2013, China's glued board, particieboard, fiberboard output reach about 2.7 hundred million m3.But prior art mainly adopts the resins such as urea aldehyde, phenolic aldehyde to realize lumber fibre gummed, harmful substances such as the easy release formaldehyde of product, free phenol and cause indoor environment severe contamination, causes the major diseases such as leukaemia.And artificial forest wood easily expand with wet and contract with dry occurs, Veneer moisture changes will cause catastrophic collapse, cause glue nail, chemical bond rupture, glued board generation layering, degradation phenomenon.Meanwhile, liquid adhesive glue applying method easily causes veneer damaged, and need adopt batch (-type) operating type, at substantial manpower, is difficult to automation equalization; The normal applying glue of fiberboard, particieboard is uneven, easily produces gum spot and precuring, causes the serious waste of adhesive and timber.
As far back as 105 years Christian eras, Cai Lun invented papermaking technology, had started fiber combination technology application again.After phenolic resins and Lauxite invention, wet laid fiber bonding technique once occupied the principal status of public economy, but there is a large amount of waste water and residue pollution; By technology upgrading improvement, dry method woody debris bonding technique is with environmental protection, the advantage such as efficient, and instead of rapidly wet laid fiber gummed, within 2013, global dry-process fiberboard output is more than 100,000,000 m3.But adopt in resinoid bond process, create the pollutants such as a large amount of formaldehyde, free phenol, human settlements safety and the life and health of people in serious threat.In order to eliminate these negative effects, Chinese scholars develops six kinds of Binderless binding technology, but still also exist that dry strength is very high, wet strength is extremely low, can not meet industrial requirement, cause fiberboard, particieboard Binderless binding technology do not applied by heavy industrialization.Adopt liquid processes in artifical plate product's paint finishing, solvent deal, up to 40-60%, not only consumes a large amount of organic solvent, and produce organic vapor pollution, cause the serious disease such as leukaemia, tuberculosis, there is fire disaster hidden danger, serious threat people life security.
In order to solve these significant problems, Formaldehyde Pollution Treatment in wood-based plate and goods has clearly been listed in " (19) agricultural product intensive processing and the modern accumulating of agriculture field by National Program for Medium-to Long-term Scientific and Technological Development, (20) agricultural-forestry biomass comprehensive development and utilization " preferential theme, this project will around the guiding theory of " outline " and requirement, to combine closely the requirement of building Socialist New and industry and local economic development, by the breakthrough of the applying glue of wood-based plate electrostatic and powder coating key technology, realize artifical plate product's Form aldehyde release and reach natural timber level, stop solvent contamination atmospheric environment in furniture covering with paint, for promoting public safety, developing rural economy and raising farmers' income provide new approach.
Summary of the invention
For the deficiencies in the prior art, the present invention adopts following technical scheme:
Electrostatic fiber sizing plate manufacturing process, comprises the steps: low molar ratio urea-formaldehyde resin viscose binder, enhancing resin, higher alcohol and organo-metallic compound to carry out composite; Organo-metallic compound modified urea-formaldehyde resin glue powder after composite chemical combination is carried out physicochemical property test; By organo-metallic compound modified urea-formaldehyde resin glue powder up to standard for test, carry out electrostatic glue spraying; Sheet material after glue spraying is mated formation, precompressed, hot pressing and sanding, form electrostatic fiber sizing plate slab; Slab is carried out physicochemical property test, test passes be required electrostatic fiber sizing plate;
Described enhancing resin is a kind of fibre reinforced resin rib, and the reinforcement of this described muscle is basalt fibre and carbon fiber mixing composition, and wherein carbon fiber quality accounts for the 10%-50% of reinforcement total fiber mass;
It is 1-10% that described material resin also comprises mass ratio, and length is the aramid fiber of 2-6mm, carbon fiber and the chopped strand such as glass fibre or basalt fibre.
Adopt technical scheme provided by the invention:
Have the functions such as high strength, high flame retardant, prosthetic Form aldehyde release, production marketing is positioned at the middle and high end client in following market: (1) is main towards users such as top-grade furniture factory, high-grade thick china factory and high end audio material, top grade decoration, high-grade floors;
(2) application of the aspect such as building trade body of wall, door-plate and building template;
(3) fire prevention and fire-retardant etc. in have the extraordinary wood-based plate of the high-quality of specific use, high added value and the high-end market of other emerging fields such as vehicle and shipbuilding, the packing of product, Production Container, sports goods and household electrical appliance light industry;
(4) portioned product reaches the developed countries such as outlet America and Europe.
Change that original medium density fibre board (MDF) product burst size of methanal in prior art is higher, not fire-resistant, the easy deficiency such as mould, Yi Chao, the former Sales Channel of the company that overcomes can only in the face of the defect of domestic low-end subscribers.
Beneficial effect of the present invention is:
(1) with low molar ratio urea-formaldehyde resin adhesive for raw material, be aided with enhancing resin, preferentially high compatibility organic metal, the modern Resin adhesive technologies of preparing such as employing emulsion polymerisation, molecule are inlayed, coordination bridging, research and development low temperature spray drying technology, the organic metal modified urea-formaldehyde resin glue powder of development mildew-resistant, water-fast, high-strength, charged, low cost;
(2) by controlling fiber moisture, solid rubber powder particle diameter and the quantity of electric charge, atomisation area, electrostatic pressure and electrostatic field region, implement applying glue to fibers amount precise hard_drawn tuhes and uniformity, exploitation electrostatic adhesive process and automated system, further improvement is mated formation, precompressed, heat pressing process, development mildew-resistant, water-fast, moistureproof, fire proofing fibre board.
