Description
Technical field
The present invention relates to photocuring polymerization field, more particularly to a kind of ultraviolet light, which cures, fills out envelope fiber glass reinforced polypropylene honeycomb
The filling method and composition of composite board (hereinafter referred to as Holypan) side.
Background technology
Photocuring technology is-and item is energy saving and clean and environment-friendly technology, and it saves energy without solvent, have to ecological environment
Protective effect, while also because its flexibility is applied to most of production fields.The side pressure poor performance of honeycomb core plate, the easy moisture absorption,
Necessary edge sealing and sealing, typically now using mental section or plastic edge banding edge sealing.
103590532 A of CN disclose a kind of edge sealing structure and its edge bonding method of cellular sandwich wallboard of shelter, its is main
Coating is mixed to form using epoxy plus putty, blade coating is in honeycomb core side face of plate material, spontaneous curing by hand.This method operation more falls
Afterwards, hand labour amount is big, is not suitable for the edge sealing of cellular mass core.
2659227 Y of CN disclose a kind of plastic sucking table top with honeycomb paper inner core banding, it includes panel, bottom plate, honeycomb paper
Inner core, side connector, panel, bottom plate are process by plastic uptake or straight forming, honeycomb paper inner core be filled in panel and bottom plate it
Between, and fix and be connected with panel, bottom plate；Side connector cladding completely or the periphery for being partly coated on honeycomb paper inner core, and with
Honeycomb paper inner core is fixed and is connected；Panel, bottom edge coincide with side connector shape mutually to recline, and fixation is connected, Bian Lian
Fitting is the reinforced frame of desktop, can also play modification beauty on the periphery of desktop.Side connection described in the patent
Part is pipe fitting or extrusion aluminium section bar or other extrusion profiles；The side connector can also be pipe fitting or extrusion profile and injection
The composite members that part or handware are formed.The side connector is Nian Jie mutually solid for glue with the joint between panel, bottom plate
Fixed or welding is mutually fixed.The side connector on the periphery that cladding or part are coated on honeycomb paper inner core completely is metal mold in the patent
Material, it is necessary to it is supporting with panel thickness, and need to fix using adhesive or fastener, it is complicated.Plastic edge banding needs special
It is costly with equipment operation.
2366469 Y of CN disclose a kind of plate, are specifically that edge sealing reinforces waterproof and dampproof paper peak sandwich panels.It is by paper
Honeycomb core and paper panel are mutually glued to be formed, wherein the surrounding grave in paper honeycomb sandwich plate fills and is closed with expanded material, and
Pole is applied on paper panel moistureproof and waterproof dope layer.The expanded material is polyester resin or polyurethane, but the intensity of the product is omited
It is micro- relatively low, and without the edge bonding method for providing this waterproof and dampproof paper peak sandwich panels.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which it is of low cost to provide a kind of edge sealing structure, can carry significantly
The lateral pressure resistant of high fiber glass reinforced polypropylene honeycomb plywood sheet and the edge banding technique of integral rigidity.
Further aim of the present invention is to provide one kind using UV-curing technology to fiber glass reinforced polypropylene honeycomb
The side of composite board fill out the composition of envelope.
In order to realize the above object present invention employs following technical scheme：
Envelope composition is filled out in a kind of side of fiber glass reinforced polypropylene honeycomb plywood sheet, including photocuring prepolymer and heat are drawn
Send out agent；The photocuring prepolymer is made of the component of following mass percent：Resin 70~90%, reactive diluent 10~
30%th, filler and pigment 5~20%, photoinitiator 4~7%, thermal initiator 2%, defoamer 0.2~0.5%, levelling agent
0.1~0.3%；The thermal initiator is room temperature thermal curing agents, its mass percent is 2%；The resin is with fragrant adoption ammonia
Ester acrylate and aliphatic polyurethane acrylate are matrix resin, using pure acrylic resin and polyester chloride acrylic ester as
Ligand resin is ligand resin, and the ratio of matrix resin and ligand resin is 6:1~4:Between 1.
Preferably, the ratio of the matrix resin and ligand resin is 5:1.
Preferably, the reactive diluent includes the one or more in HDDA, TEGDA, TPGDA, TMPTMA
And the mass percent of ODA, the ODA are 1~5%.Wherein HDDA is 1,6 hexanediyl esters, and TEGDA is three second two
Alcohol diacrylate, TPGDA are tripropylene glycol diacrylate, and TMPTMA is trimethylol-propane trimethacrylate, ODA
For octadecyl acrylate, the effect for adding a certain amount of ODA is to improve to cure post-shrinkage ratio and reduce surface to open
Power.
Preferably, the room temperature thermal curing agents are the one or more in modified imidazole class and amine curing agent.
Room temperature thermal curing agents can be but be not limited only to above-mentioned raw materials.
A kind of side filling method of fiber glass reinforced polypropylene honeycomb plywood sheet, comprises the following steps：
1) dedusting cleaning is carried out to the side of fiber glass reinforced polypropylene honeycomb plywood sheet, the burr for then blowing down surface is broken
Bits；
2) side after handling blowing is surface-treated；
3) cloth or film for preventing from oozing under coating are accompanied between two adjacent plates, is rolled between plate by both sides
Axis clamping prevents coating from being leaked under gap；
4) envelope composition is filled out with a kind of side of fiber glass reinforced polypropylene honeycomb plywood sheet of as above any one of them to make
For photocureable coating, photocureable coating is sprayed on the side of fiber glass reinforced polypropylene honeycomb plywood sheet by spraying solidification equipment
Side, stands 20min, photocuring is carried out by ultraviolet light after levelling.
Wherein, the photo curing condition in step 4 is：Light source is the ultraviolet lamp of 800w~10000w, and light source increases from glass
The distance of the side of strong polypropylene honeycomb composite board is 15~30cm, and hardening time is 3~30s.
Preferably, the spraying solidification equipment in step 4 includes transmission device, some groups of last items, spray equipment and purple light
Lamp, the last item two is one group, is symmetricly set on the both sides of transmission device, transmission direction of some groups of last items along transmission device
It is placed equidistant with；Multi-disc fiber glass reinforced polypropylene honeycomb plywood sheet after step 1~3 are handled is placed on transmission device, position
Between two last items in same group；Spray equipment and ultraviolet light are located at the top of fiber glass reinforced polypropylene honeycomb composite plate,
Partition plate is equipped between spray equipment and ultraviolet light；Photocureable coating is housed in the spray equipment, is uniformly distributed on spray equipment
There are multiple spray orifices；When being sprayed, transmission device is transmitted toward a direction, and when being cured, transmission device reversely transmits.
Compared with prior art, the present invention has the following advantages：(1) photocuring obtained using the formula of the present invention is applied
The intensity of material, energy rapid curing and curing post-crosslinking thing is big.(2) edge sealing structure that edge banding technique of the invention obtains is produced into
This is low, production efficiency is high, can greatly improve the crushing resistance and integral rigidity of fiber glass reinforced polypropylene honeycomb plywood sheet, play side
Frame strengthens and waterproof sealing effect.
