In first example approach, relate to the production of glued board, on laminated wood, coat resin, laminate is stacked together and pressurizes impel their together bonding and/or heating to make resin solidification make the laminate strong binding together by being clipped in resin between adjacent layers.Must apply the quite a long time in the pressurization of routine and heating production method, for example several minutes has increased manufacturing time and manufacturing expense.According to the present invention, catalyst distribution is in whole described resin.Described catalyzer can be a propylene carbonate, vinyl carbonate or other catalyzer that is fit to, and it causes and solidifies described resin with plank between bonding successive layers.Yet,, will be difficult to or can not be satisfactorily or/and described effectively production process if solidify to cause too early or carry out too soon.For example,, can not easily be coated with laminate if carry out when laminate solidifies during at coating resin, and, even coated, the bond strength between laminate is also had adverse influence.
In order to overcome this shortcoming that may exist, come that it is caused solidified in the resin and discharge and control by sealing described catalyzer.Obtain like this to seal by the catalyst microcapsule that in the presence of encapsulating material, goes out to be coated with encapsulating material with the described Catalyst Production of ultrasonic wave radiation.Although these resin capsule of sealing are distributed in the whole resin, described coating is kept apart catalyzer and resin.In this case, resin can be resembled on the laminate that the description of front is applied to, can not begin, therefore will can not influence this process and discharge described catalyzer up to these breakage of particles and enter in the resin but solidify.Can cause producing by the described capsule of ultrasonic wave radiation or heating or some other appropriate means and break.
In a kind of encapsulating method as selection, catalyzer is adsorbed on a kind of particle surface of inertial base, and described particle is using ultrasound wave radiation coating packaged material once more.The coated particle size generally can be the 0.5-1000 micron in both cases.
Described catalyzer can be any of following material, or their mixture: organo-peroxide, as dibenzoyl peroxide, methylethyl ketone peroxide, cumene hydroperoxide, acetylacetone peroxide (merchandising is called Triganox 44B), TBPB tertiary butyl perbenzoate (merchandising is called TriganoxC), the tertiary butyl-2-ethylhexanoate (merchandising is called Triganox 21), t-butyl peroxy-3,5,5-tri-methyl hexanoic acid ester (merchandising is called Triganox42s), cumene hydroperoxide (merchandising is called Triganox K-80), two (4-tert-butylcyclohexyl percarbonic acid hydrogen esters (merchandising is called Perkadox 16); Amine catalyst, for example diethyl tetramine, triethylamine isocyanic ester, boron trifluoride; UV-curing catalysts, alkyl carbonate, for example propylene and vinyl carbonate; Inorganic and organic acid is as formic acid, toluenesulphonic acids or sulfuric acid.
Also can use accelerator as cobalt octoate (merchandising is called NL-49-P), diethyl-aniline (merchandising is called NL-64-10P).
Described encapsulating material can be following any: gelatin, thermosetting resin, fats, paraffin, thermoplastics, polymkeric substance or silane compound or be any of the encapsulating material described in the common unsettled international application of WO98/26865 in the applicant's publication No..
Described resin can be any of following resin or their any mixture: vibrin, vinyl ester resin, resol, Resins, epoxy, acrylic resin, trimeric cyanamide/urea-formaldehyde resin, resol.
In another example, catalyzer is to catch by absorbing in the suitable matrix rather than as previously described absorption.A kind of suitable matrix is a Pericarppium Armeniacae Amarum, it have help absorbing/adsorptive catalyst enters the surface in its vesicular structure.Though can use other catalyzer and resin (for example as describe in detail above), preferred described catalyzer is a formic acid, described resin is Melamine/urea-formaldehyde resin.
The method of producing Pericarppium Armeniacae Amarum formic acid/toluenesulphonic acids catalystic material is as follows:
ⅰ) at first with described formic acid/toluenesulphonic acids dissolution/go in the acetone.Acetone enters the carrier solvent of the vesicular structure of Pericarppium Armeniacae Amarum as described acid catalyst.
ⅱ) then Pericarppium Armeniacae Amarum is added in described acid/acetone mixture.
ⅲ) with described acid/acetone/Pericarppium Armeniacae Amarum mixture 20kHz, 400 watts ultrasonic fault detection 3-5 minute up to described acetone/acid absorb/adsorb to advance in the described Pericarppium Armeniacae Amarum structure.Phenomenon by the obvious thickening of described mixture can easily be observed this process.Using a reason of solvent is for ultrasonic energy is worked effectively to very firm Pericarppium Armeniacae Amarum.Require excessive liquid (being acetone) to produce air pocket.When cavitation bubble is broken, produced a large amount of energy sources/shockwave, be exactly that this energy orders about described liquid mixture and enters into described Pericarppium Armeniacae Amarum structure.
ⅳ) described acetone solvent is removed from slurry mixture, only stayed described acid catalyst and be embedded in the described Pericarppium Armeniacae Amarum by drying means.Can use condenser that described acetone is removed and recycled.Described Pericarppium Armeniacae Amarum/acid catalyst product be a kind of can quite free-pouring powder, it can easily be distributed in the resin.Use acetone to be as solvent because:
