Specific embodiment
It is understandable in order to enable the above objects, features and advantages of the present invention to become apparent, below to of the invention specific
Embodiment is described in detail.
, furniture edge sealing glue raw material Selecting research
Furniture edge sealing glue is acted on furniture, meeting and direct body contact, therefore using EVA as colloidal materials, asepsis environment-protecting.?
In this research selection based on EVA made of ethene-vinyl acetate binary copolymerization resin, select that multiple VA contents are high, melting means
Low EVA model, by the experiment screening of different ratio, pick out the model that hardness is high, toughness is strong include EVA-UL7711,
EVA-638,EVA-654.In order to guarantee the heat resistance in colloid later period, the polyolefin of high softening-point low viscosity, Neng Gouti is added
Rise the heat resistance of colloid.
Furniture edge sealing glue acts on wood furniture mostly, therefore has certain demand to weatherability and cohesive force.In order to
Weatherability and cohesive force are promoted, needs that tackifying resin is added, picks out the petroleum that heatproof is good, softening point is high in this research selection
Resin, being aided with viscosity, good rosin resin finally makes Petropols by the experiment screening of different ratio: rosin resin is with 7:2
Compound proportion be blended, guarantee the weatherability and cohesive force of colloid.
Further, it is the caking property and penetration that improve colloid and timber or composite material, prevents PVC edge band from occurring
The case where falling off is ground in this research selection by carrying out compounding to the big synthetic wax of multiple hardness and low temperature resistant good microwax
Study carefully, it is contemplated that increase the mobility of colloid, to meet the colloid polyethylene wax convenient, preferably coupling agent modified in construction coating,
By the way that coupling agent modified polyethylene wax is added in colloid, colloid and timber or composite material are can significantly improve and improved
Caking property and penetration.
In addition, by adding a small amount of maleic anhydride wax grafting wax oligomer polarity can be dramatically increased, to promote colloid
Permeability and caking property increase substantially the adhesion strength of colloid.
Appearance is white after traditional hot melt adhesive solidification, but being used on furniture can be than more prominent, unsightly.It therefore can be with
By not homochromy number colorant of addition, the color close to plate or composite material is debugged out, to reach the effect of beautification edge sealing
Fruit.
Based on above-mentioned, the selection of this furniture edge sealing glue raw material includes EVA-638, EVA-654, EVA-UL7711, polyolefin, increasing
Viscosity resin, polyethylene wax and the grafting of maleic anhydride wax, are formulated: EVA-UL7711,8- by following component example in mass ratio
12 parts；EVA-654,24-36 parts；EVA-638,24-36 parts；Polyolefin, 2-5 parts；Tackifying resin, 9-18 parts；Polyethylene wax, 1-
3 parts；The grafting of maleic anhydride wax, 1-2 parts.Wherein, tackifying resin is made of Petropols and rosin resin, Petropols and rosin
The mixed proportion of resin is 7:2.
, furniture edge sealing glue quality proportioning preferred research

It tests based on the above embodiment, this furniture edge sealing glue raw material is preferably formulated by following component example in mass ratio: EVA-
UL7711,10 parts；EVA-654,30 parts；EVA-638,30 parts；Polyolefin, 3 parts；Tackifying resin, 18 parts；Polyethylene wax, 2 parts；
The grafting of maleic anhydride wax, 2 parts.18 parts of tackifying resins are by 14 parts of Petropols and 4 parts of rosin resin mixing.
, furniture edge sealing glue production technology research
Traditional hot melt adhesive production uses water ring pelletizing.The water ring pelletizing is the centrifugal action after film surface pelletizing by itself
Colloid, which is thrown to inside water circulating barrel, follows water outflow again through being dehydrated.
Therefore, which uses underwater twin-screw skill extrusion process in production technology.The underwater cutpellet
Die face is just gone out with regard to pelletizing in colloid, has not needed centrifugal action and throw away it, but direct hydraulic pressure breaks through die face and goes out dehydration.Glue
Body, again through the secondary kneading of screw machine, realizes after being mixed by reaction kettle and mixes more uniform, granulation underwater plastic emitting speed
Fastly, impurity is few, and micelle is dry, keeps colloid appearance even glossy.
From the above mentioned, the furniture edge sealing glue the preparation method comprises the following steps: the raw material of aforementioned proportion is blended at 150 DEG C stir to
It obtains colloid admixture within few 3 hours, is produced by double screw extruder underwater cutpellet.
The key technical indexes of furniture edge sealing glue that the present invention is described: 1. appearances: yellow particle (be not added with colorant it
Before)；2. apparent viscosity: 16000 ± 2000mpa.s (180 DEG C, rotational viscometer)；3. softening point: 130 ± 10 DEG C (are pressed GB/T
15332-1994 standard)；4. the open hour, s :≤2(presses HG/T 3716-2003 standard)；5. hardness: >=95(shore hardness
Instrument).
