Description
Technical field
The present invention relates to a kind of Wood-based Panel Production method, particularly the manufacture method of moistureproof full Eucalyptus lamination decoration panel.
Background technology
Eucalyptus is the general designation that Myrtaceae Myrtaceae eucalyptus belongs to Eucalyptus plant, and eucalyptus strong adaptability also can grow in dead soil, and fast growth, nursing cost is low, and therefore cultivated area increases year by year.Eucalyptus Wood is red, glossy, without special odor, texture is staggered, structure is close, material is firmly heavy, flexible.Level larger eucalyptus in footpath is by being peeled into veneer, glued board or laminated veneer lumber is produced as central layer, and small diameter grade, brush wood or the eucalyptus that is difficult to rotary-cut are processed into wood chip, for papermaking or producd fibers plate, therefore the comprehensive utilization ratio of eucalyptus can be increased to more than 90%.China successfully developed high-performance Eucalyptus recombinant material, Eucalyptus laminated veneer lumber, bamboo eucalyptus composite, thick core eucalyptus composite plate made from solid wood and without aldehyde Eucalyptus plywood making technology etc. in recent years, and Eucalyptus is more and more universal in the application of wood-based plate.
Eucalyptus structure is close, material is hard, Eucalyptus the laminated veneer lumber easy delamination, particularly Long-Time Service of making or meet the water moisture absorption or after being exposed to the sun, easily play drum, distortion.Particularly with the decoration panel that full Eucalyptus laminated board is made, be widely used in office furniture, the probability contacted with water is very high, once water inlet, if wiping not in time, causes foaming, distortion with regard to being easy to because of imbibition.Its moisture resistance performance is not strong yet, less stable in a humidity environment.The method addressed this is that at present increases the resin added of unit are and the adhesive of use water-tolerant, to improve Eucalyptus bonding force between layers and the resistance to water of glued board.But resin added increases, and burst size of methanal is difficult to the burst size of methanal standard reaching national requirements.Adopt without aldehyde adhesive, cost is difficult to again accept.
Summary of the invention
The object of this invention is to provide a kind of moistureproof full Eucalyptus lamination decoration panel and production method thereof, being the humidity resistance improving full Eucalyptus wood-based plate on the one hand by this method, is reduce burst size of methanal on the one hand.
The production method of protection against the tide of the present invention full Eucalyptus lamination decoration panel, the base material that this wood-based plate is bondd by adhesive by multilayer Eucalyptus veneer and melamine gum dipped paper high temperature overlay and form, comprise veneer sorting, gluing, cold pressing, hot pressing, stacking health and paste melamine gum dipped paper step, it is characterized in that: adopt and cold pressing for three times and three hot pressing, twice thermostatic chamber leaves standstill health and twice heat radiation health; Described temperature of colding pressing is room temperature, and pressure is 0.8 ~ 1.0MPa, and hot pressing pressure is 1.5 ~ 2.0MPa; The temperature of first time hot pressing is 120 ~ 125 DEG C; The temperature of second time hot pressing is 115 ~ 120 DEG C, and the temperature of third time hot pressing is 125 ~ 130 DEG C; It is 80 ~ 90 DEG C that described thermostatic chamber leaves standstill health temperature, and the time is 4 ~ 6h; Described heat radiation health is that thermostatic chamber gravity-flow ventilation is cooled to room temperature, and the time is 3 ~ 4h; It is at 160 DEG C that substrate surface pastes melamine gum dipped paper, and pressure is carry out under 1.5 ~ 2.0Mpa.Eventually pass heat radiation to arrange, beat limit, obtain moistureproof full Eucalyptus lamination decoration panel.
Above-described product, reduce the burst size of formaldehyde, first from improvement adhesive-preparing technology, by improving adhesive-preparing technology, will make raw material formaldehyde almost or complete reaction, reducing the residual quantity of formaldehyde.The employing of this adhesive-preparing technology is disposable adds formaldehyde, adds urea at twice, and the method for a melamine promotes the complete reaction of formaldehyde.Formaldehyde is added in reactor, be 2 ~ 2.5 by formic acid adjust ph, add the polyvinyl alcohol of formaldehyde weight 0.5 ~ 0.6%, add the urea of formaldehyde weight 10%, be warming up to 50 DEG C, insulation reaction 30min, the pH value regulating reactant liquor is 8 ~ 8.5, add the urea of formaldehyde weight 25%, add the melamine of formaldehyde weight 1%, be warming up to 90 ~ 95 DEG C, insulation reaction 90min, reaction terminates rear inspection, if also containing formaldehyde, add appropriate urea or melamine continuation reaction, until detect the content < 5mg/L of formaldehyde, adding alkali regulates the pH value of reaction end liquid to be 7.2 ~ 7.5.Amino generation polycondensation reaction on aldehyde radical on formaldehyde molecule and urea or melamine molecule, generate macromolecular compound, along with constantly carrying out of condensation reaction, the molecular weight of the material that polycondensation reaction generates constantly increases, reactant liquor viscosity is caused to increase, mobility is deteriorated, reduce the probability of the collision of formaldehyde and the urea do not reacted, and the high polymer gel formaldehyde generated and urea, cause the formaldehyde outside high polymer and urea effectively internally not to supplement, cause the inner polymer molecular weight generated low.Polymer molecular weight is low, easily degrades, release formaldehyde.Therefore the one-step technology before, namely disposablely adds formaldehyde and urea, and easily cause reaction in early stage violent, gelatin phenomenon is very serious.So-called gelatin phenomenon is exactly in polymerisation, generate high molecular polymer encase polymerization single polymerization monomer, the also polymerization reaction take place of the monomer inside high molecular polymer, but due to outside monomer cannot give the inside reaction supplement, therefore, the polymer molecular weight that wraps of high molecular polymer is very little.The polymer substance molecular weight distribution that this phenomenon causes polymerisation to obtain is very wide, and level of residual monomers is very large.Because one-step method reaction in early stage is violent, reaction polymer molecular weight in early stage is very large, and later stage molecular weight is little, the formaldehyde of non-complete reaction is many, the adhesive molecular weight distribution made is very wide, the artificial board formaldehyde burst size made with this adhesive is very large, and high risks user's is healthy.Added the new technology of urea by gradation, avoid reaction in early stage too violent, the polymer molecular weight of reacting generation after adding urea for the first time can not be very large, because the amount that first time adds urea is little, the polymer generated is few, and viscosity is low, the good fluidity of material, do not have the phenomenon of gel, therefore the molecular weight distribution of polymer is comparatively even, and second time adds urea, because the concentration of formaldehyde in reactant liquor has reduced much, reaction is also relatively more steady, and therefore gelatin phenomenon is not very serious.
Formaldehyde is complete reaction almost, molecular weight of polycondensates narrowly distributing, and molecular weight is high, difficult degradation, and as the adhesive of veneer, burst size of methanal is naturally low.
The good effect that the present invention produces:
1. protection against the tide of the present invention full Eucalyptus lamination decoration panel production technology adopt cold pressing for three times, three hot pressing, twice thermostatic chamber leaves standstill the production technology of health and twice heat radiation health, the stress of Eucalyptus intralamellar part can be eliminated, reduce the possibility that finished product meets water, the moisture absorption plays drum, is out of shape, improve the humidity resistance of finished product.Use the technique in the present invention, finished product burst size of methanal can also be reduced, protect the health of consumer.
2. the urea-formaldehyde resin adhesive that protection against the tide of the present invention full Eucalyptus lamination decoration panel adopts is the technique adopting gradation to add urea, formaldehyde monomers less residue, and in conjunction with the repeatedly cold, hot pressure technique that the present invention adopts, the burst size of methanal of finished product is less, more environmental protection.
