The initiator is the aqueous solution of the ammonium persulfate that mass fraction is 1~5% or 1~5% potassium peroxydisulfate.
Patch wood skin glue provided by the present invention employs multiple unit resins and enters copolymerization, has obtained multi-copolymerization emulsion, has led to
Optimization and improved formulations are crossed, superpower resistant to hydrolysis ability and weatherability changing capability (high temperature not desaturation, low temperature not tortoise is made it have
Split), there is lasting internal plasticization performance again, the function such as bonding strength is extremely strong.Would not be by because of bubble with the sheet material of this glue
Water, high/low temperature, the influence of thump and there is the phenomenon bubbled, come unglued.
Further, in the patch wood skin glue, 2-4 parts of preservative can also be included.The preservative can be Kathon CG, institute
Stating can selectively add as needed in patch wood skin glue, and its main function is optimization effective life.
The patch wood skin glue preparation method is also provided in the present invention, comprised the steps:
(1) deionized water is put into reactor, polyvinyl alcohol rising temperature for dissolving is added, is cooled to 75~85 DEG C;
(2) by reaction monomers vinylacetate, tertiary ethylene carbonate, n-BMA, acrylic acid, metering system
It is put into dropping tank and is well mixed after acid metering;
(3) extraordinary cross-linking monomer, environmentally friendly response type anion emulsifier, environmentally friendly response type nonionic are added in reactor
Emulsifying agent;
(4) mix monomer is added dropwise, while the initiator of total monomer weight 0.1~0.2% is added dropwise, and was dripped in 3~5 hours
Add into;
(5) 85~95 DEG C of 40~60min of curing are warming up to after being added dropwise to complete;
(6) be cooled to 35~45 DEG C, add environment-friendly plasticizer and preservative it is well mixed after discharging filter and package.
Patch wood skin glue provided in the present invention, with lasting internal plasticization and pliability, bonding force is strong, water-fast, resistance to
Acid-base property is good, non-aging, and wet strength is high, has fabulous anti-flammability, is not trickled at 120 DEG C above freezing;Subzero 50 DEG C are not cracked, nothing
Malicious free from extraneous odour, it is safe and reliable, it is easy to use.Fitting for PLASTIC LAMINATED and wood skin is applicable not only to, various sheet materials are also suitable for (fine
Tie up plate, clamping plate, hard board) pasted with more than 0.3mm wood skin, it is adapted to machinery gluing and manual gluing.
And compared with urea-formaldehyde glue, aqueous plaster wood skin glue of the present invention has advantages below:(1) urea-formaldehyde glue is solid using preceding needing
Agent is well mixed, it is necessary to use as early as possible, and present invention patch wood skin glue need not add curing agent, can directly use;(2) use
When ureaformaldehyde glue wood skin and sheet material, urea-formaldehyde glue can ooze out from the wooden eye of wood skin, and can block wooden eye, in veneer surface japanning
Afterwards, veneer surface is because the urea-formaldehyde glue oozed out causes veneer surface after japanning uneven, and uses present invention patch wood skin glue not
Wooden eye can be blocked, colored paint can penetrate into wooden eye, and colouring is uniform natural;(3) because urea-formaldehyde glue can block wooden eye, therefore in hot pressing
In, the air remained between wood skin and sheet material can not be appeared from wooden eye, foaming phenomena occur, and present invention patch wood skin glue is in warm
Residual air can shed from wooden eye during pressure, prevent foaming phenomena;(4) due to there is organic volatile in urea-formaldehyde glue
Matter, in hot pressing, produces irritative gas, and human respiratory tract is caused to stimulate and environment is polluted, and this hair
Bright patch wood skin glue is due to being water-base cement, without organic volatile substance, and unpleasant or stimulation row will not be also produced even if in hot pressing
Gas.
With reference to embodiment, the invention will be further described.
