Abstract
Glue for manually pasting wood veneer is a special adhesive for manually pasting wood veneer on a wood furniture surface. The glue adopts VAE copolymer emulsion and polyvinyl alcohol as main raw materials, and is blended with auxiliary agents and additives. The glue of the invention has the characteristics of cold working, single component, rapid curing, good adhesion, and flat adhesion.
Description
Technical field
The present invention relates to a kind of tackiness agent of woodwork industry, especially a kind of tackiness agent for the various wooden skins of manual cold-adhered.
Background technology
In woodwork industry, the use of tackiness agent is very extensive now, but it is fewer to manufacture the outstanding problem that exists in process and be the special-purpose adhesive with good bonding performance, particularly be exclusively used in the bonding product of wooden skin less, and existing wooden hide glue is multiplex to the hot glue machine, the manual cold-adhered of cold glue is not ideal enough, and weathering resistance, water tolerance are all relatively poor, set time is longer, and what have is easy to foaming.
Summary of the invention
The objective of the invention is to develop a kind of manual cold bonding agent of pasting the tool superperformance of wooden skin special use.
The objective of the invention is accomplished like this:
As linking agent, cross-linking polyvinyl alcohol prepares polyaminoester emulsion, then carries out the modification blend with the VAE emulsion with 4,4 ' diphenylmethanediisocyanate (MDI) for we.
VAE is the vae copolymer emulsion namely, is the abbreviation of vinyl acetate-ethylene copolymerization emulsions, is take vinyl acetate between to for plastic and vinyl monomer as basic raw material, the macromolecule emulsion that forms by the emulsion polymerisation process copolymerization.The VAE emulsion has good mechanical property, and the emulsion particle averageparticle is little, and good cold bonding and very fast curing speed are arranged.Can increase simultaneously dried wet tenacity, toughness, the glossiness of wooden skin, improve color stability.
Proportioning raw materials of the present invention:
Polyvinyl alcohol 3-7%,
Water 45-65%,
MDI 5-15％、
VAE(706) 5-35％、
OP-10 0.1-0.15％、
Urea 1-5%,
Light calcium carbonate 1-5%,
Secondary ammonium phosphate 0.1-0.15%,
Antioxidant 1010 0.005-0.01%.
Raw material after weighing, first enters the polyethylene alcohol and water in dissolution kettle in proportion, heats to 90 degrees centigrade to make polyvinyl alcohol fully dissolve (2 hours).
Polyvinyl alcohol solution (PVA) and MDI, OP-10 are entered reactor, heat to 55 degrees centigrade, stir and be scattered in PVA fully to MDI in 1 hour.
Add 706 type VAE, 45 degrees centigrade were stirred 1 hour again.
Add at last urea, Secondary ammonium phosphate, light calcium carbonate, antioxidant.Stirred one hour.Discharging.
The present invention has following advantage owing to adopting technique scheme:
Glue is fit to manual cold bonding and pastes, and cohesiveness is high, quick solidifying, and glue layer is water-fast, heat-resisting, not yielding.
Embodiment:
Embodiment:
Polyvinyl alcohol 4%,
Water 50%,
MDI 15％、
VAE(706) 25％、
OP-10 0.15％、
Urea 2.69%,
Light calcium carbonate 3%,
Secondary ammonium phosphate 0.15%,
Antioxidant 1010 0.01%.
Raw material after weighing, first enters the polyethylene alcohol and water in dissolution kettle in proportion, heats to 90 degrees centigrade to make polyvinyl alcohol fully dissolve (2 hours).
Polyvinyl alcohol solution (PVA) and MDI, OP-10 are entered reactor, heat to 55 degrees centigrade, stir and be scattered in PVA fully to MDI in 1 hour.
Add 706 type VAE, 45 degrees centigrade were stirred 1 hour again.
Add at last urea, Secondary ammonium phosphate, light calcium carbonate, antioxidant.Stirred one hour, question response still temperature is down to can discharging below 30 degrees centigrade.
The manual rubberizing water of wooden skin of the present invention, performance equals to hot glue, and single-component is simple to operate, pastes wooden skin smooth, can not bubble, and the application space is huge in pasting wooden skin furniture making.
