Description
Technical field
The present invention relates to coda wave plate technical field of manufacturing process, specially a kind of lamination process of coda wave plate.
Background technique
Surfing is the extreme sport using wave as power, in recent years by the concern and extreme sport of more and more people
Person is keen to one of the project of challenge, and coda wave plate is to have just emerged and rapidly develop in recent years a universal water skiing individual event.Coda wave plate
External form exactly like the veneer of skiing, be one and be about 130 centimeters or so, wide about 60 centimeters or so of plate body, plate body lower part both ends
Equipped with tail fin, table is equipped with fixed footmuff close to middle part on plate body, can make one to experience the stimulation of high speed slide bring, and can make
Human body can turn over, turn, jumping, the bring that jumps " object for appreciation " is happy, and people is allowed to enjoy the tender feeling and sports band of summer blue sky clear water to the full
To the infinite enjoyment of people.
Existing coda wave plate manufacture craft is to increase the accessories such as tail fin and fixed footmuff on the basis of the production of surfboard,
And traditional surfboard manufacture craft, inner core plates are predominantly cut by molding machine, output fitting bore, in inner core plates outer surface
It makees cloth and fills epoxy resin lamination, then polished again, the processes such as sealing, wherein lamination process plays the quality of coda wave plate
To key effect, lamination is not secured enough, will cause the structural soundness decline of entire coda wave plate, is easy cracking degumming, uses the longevity
Life shortens, and existing manufacture craft causes fabrication cycle longer in order to avoid problems using repeated multiple times gluing, also easily makes
It is larger at weight, it is influenced using quality, while traditional epoxy resin used and epoxyn itself are nontoxic, but by
In being added to solvent and other Toxics during the preparation process, therefore many epoxy resin are therefore " toxic ", for this purpose, it is proposed that
A kind of lamination process of coda wave plate.
Summary of the invention

Cut out glass cloth and asbestos cloth, the quantity of glass cloth and asbestos cloth is no less than 2；
Sp3: 15-45s in resin adhesive liquid is immersed according to the glass cloth and asbestos cloth cut out in Sp2 respectively, utilizes baking oven
The good glass cloth of impregnation and asbestos cloth are dried, drying time is according to baking oven length and glass cloth and asbestos cloth
Depending on the speed of service；
Sp4: the outer of polystyrene inner core is uniformly applied to using the mixed system of aqueous epoxy resins and waterborne curing agent
2 glass cloth after Sp3 impregnation drying and processing after being heated to moisture evaporation, are wrapped in the outer of polystyrene inner core by surface
Surface, and the edge of 2 glass cloth is overlapped in the side of polystyrene inner core, scrapes glass cloth surface using scraper plate and makes
The mixed system of aqueous epoxy resins and waterborne curing agent permeate glass cloth, the aqueous epoxy resins of extra exudation with it is aqueous solidified
The mixed system of agent is uniformly applied to the edge of 2 glass cloth in the overlapped place in the side of polystyrene inner core, scrapes to glass
Until phenomena such as glass cloth edge fold, nose and bubble；
Sp5: aqueous epoxy resins and waterborne curing agent are smeared in the outer surface of the side glass cloth of polystyrene inner core
Asbestos cloth after being heated to moisture evaporation, is wrapped in the side of polystyrene inner core and can cover 2 glass cloth by mixed system
Overlapping in the side of polystyrene inner core spontaneously dries 1.5-3h, obtained coda wave boards half-finished product；
Sp6: one layer of asbestos cloth is wrapped up into the outer surface of the obtained coda wave boards half-finished product of Sp5, paints one layer of water-base epoxy tree
The mixed system of rouge and waterborne curing agent carries out sealing, enters mold and is press-formed in the environment of 25-28 DEG C, and rear demoulding stands dry
It is dry；
Sp7: most afterwards through sanding and polishing to smooth surface.
Preferably, the weight ratio of the mixed system of aqueous epoxy resins and waterborne curing agent is 10:(1- in the Sp4
1.5)。
Preferably, the edge of asbestos cloth exceeds the outer surface 0.8-1 centimeters loose of upper and lower level glass cloth in the Sp4.
Preferably, the smearing thickness of the mixed system of aqueous epoxy resins and waterborne curing agent is 1.5- in the Sp4
2Kg/m2。
Preferably, briquetting pressure is 7-10MPa in the Sp6, and the extrusion forming time is 60-80s, and the standing and drying time is
