Specific implementation mode
For make present invention solves the technical problem that, the technical solution that uses and the technique effect that reaches it is clearer, below
The technical solution further illustrated the present invention in conjunction with attached drawing and by specific implementation mode.
Method is overlayed the embodiment provides a kind of fire-proof plate, with reference to 1~Fig. 3 of figure, method is overlayed and mainly wraps
Include following steps：
S1：Coating hot-melt adhesive 3 on substrate 1, hot melt adhesive 3 are formed after being heated by solid meltability glue.
S2：The face paste that hot melt adhesive 3 is coated on cover board 2 and substrate 1 is closed and pressurizeed.
In above-mentioned steps, adhesive of the hot melt adhesive 3 as bonding cover board 2 and substrate 1 is used.Due to can by solid
Fusibleness glue (for example, by EVA (Ethylene Vinyl Acetate Copolymer, ethylene-vinyl acetate copolymer) resin,
Tackifier, viscosity modifier and antioxidant are formed) it is not aqueous in the hot melt adhesive 3 that is formed of hot melt, it can be to avoid coating and overlaying
During (fitting and pressurization), cover board 2 and 1 water swelling of substrate deformation improve the quality of fire-proof plate.Further, since not
Aqueous, the hardening time of hot melt adhesive 3 is short, overlays the time accordingly and can shorten, improves the production efficiency of fire-proof plate.At this
In embodiment, pressing time can only be set as 40s~70s, you can so that secure fit between cover board 2 and substrate 1, greatly
Ground improves the production efficiency of fire-proof plate.
Certainly, it is coating hot-melt adhesive 3 on substrate 1 in above-mentioned steps S1.It is obvious also possible to be coated on cover board 2
After hot melt adhesive 3, it is bonded with substrate 1.Further, it is also possible to after being coated with hot melt adhesive 3 on substrate 1 and cover board 2, the two fitting.
In addition, after coating hot-melt adhesive 3, before the face paste for being coated with hot melt adhesive 3 on cover board 2 and substrate 1 is closed,
Can also include：
S3：Cover board 2 and substrate 1 are aligned.
Alignment can be by being accomplished manually, for example cover board 2 is manually aligned to the surface for being covered in substrate 1, using adding
Pressure.
In the present embodiment, the temperature of hot melt adhesive 3 is 220 DEG C~250 DEG C, can be kept at hot melt adhesive 3 at such temperature
In liquid, hot melt adhesive 3 is avoided to cure and can not coat, or is just carried in substrate 1 and the also not preferably alignment fitting of cover board 2
Preceding solidification influences to use.
In the present embodiment, hot melt adhesive 3 can be coated by glue application machine.As shown in Figure 1, glue application machine is arranged
Have a glue spreader 4 of steel, glue spreader 4 be used for by hot melt adhesive 3 along circumferential surface be uniformly dispersed after be coated on the plank for needing to coat, than
As cover board 2 or substrate 1.Since in the present embodiment, therefore the temperature of hot melt adhesive 3, can be selected at 220 DEG C~250 DEG C
The glue spreader 4 of steel, to adapt to 220 DEG C~250 DEG C of temperature.In addition, the circumferential surface of glue spreader 4 is provided with grid line, grid line
The surface area of 4 circumferential surface of glue spreader can be increased so that stickiness bigger between the circumferential surface and hot melt adhesive of glue spreader 4 increases gluing
The thickness of hot melt adhesive on 4 circumferential surface of roller increases the band glue amount of the circumferential surface of glue spreader 4, is conducive to coat heat on substrate 1 or cover board 2
Melten gel.Grid line can be formed by radium-shine formation, or other modes.
In order to which hot melt adhesive 3 to be dispersed in the surface of glue spreader 4 well, in the present embodiment, glue application machine by
Glue scraping plate 5 is arranged in the peripheral surface of nearly glue spreader 4, and glue scraping plate 5 is arranged along the axial direction of glue spreader 4, and glue scraping plate 5 is angularly disposed, with
Opening up charging spout 6 is formed with the peripheral surface of glue spreader 4, charging spout 6 is for adding hot melt adhesive 3.Hot melt adhesive 3 constantly adds
It is added in charging spout 6, glue spreader 4 is in rotation, you can constantly by the hot melt adhesive volume 3 in charging spout 6 in the periphery of glue spreader 4
Face.By hot melt adhesive 3, the stickiness of itself is influenced, and during glue spreader 4 rotates, 4 surface of glue spreader can form one layer of heat
Melt layer.By adjusting the spacing between glue scraping plate 5 and the peripheral surface of glue spreader 4, you can the hot melt adhesive on adjustment glue spreader 4
3 thickness.Charging spout 6 itself also can be as the buffer area of hot melt adhesive 3.Axial direction due to glue scraping plate 5 along glue spreader 4 is arranged, because
This, can also be covered with hot melt adhesive 3 on the axial direction of glue spreader 4.In use, glue spreader 4 is pressed in plank (the either substrate of cover board 2
1) surface, when rotation, can drive plank to move, meanwhile, coat one layer of hot melt adhesive 3 on the surface of plank.Such mode is not
Only coating is uniform, and easy to use.In addition, conveying roller can be also arranged in the bottom of glue spreader 4 in glue application machine, for defeated
Send plank.
In order to make hot melt adhesive 3 be consistent as possible in the thickness on the surface of glue spreader 4, on the surface of plank
The thickness of the hot melt adhesive 3 of coating is also consistent, and keeps the structural strength of each region after being bonded consistent, can be by glue spreader 4
Rotation direction be set as from the opening of charging spout 6 to the direction of slot bottom, extra hot melt adhesive 3 is scraped off by glue scraping plate 5, keep
The hot melt adhesive 3 on 4 surface of glue spreader is evenly distributed.
In the present embodiment, hot melt adhesive 3 can be heated by colloidal sol stove, and pump is additionally provided in colloidal sol stove, and pump is applied with glue
Cloth machine is connected to, and hot melt adhesive 3 is transported at glue spreader 4.The outlet of pump is connected to by pipeline at charging spout 6, is added in time
Hot melt adhesive 3.
In the present embodiment, as shown in figure 3, cover board 2 and substrate 1 can be pressurizeed by press, press includes multipair interval
The pressure roller 7 of setting, cover board 2 and substrate 1 are passed through between two pressure rollers 7 being arranged in pairs, and are squeezed by the pressure roller 7 of both sides, are kept
The close abutting of cover board 2 and substrate 1 is bonded cover board 2 and substrate 1 securely when curing convenient for hot melt adhesive 3.Specifically, can be with
40 pairs of pressure rollers 7 are set, and in two pressure rollers 7 being arranged in pairs, one is the fixed fixed roll 71 in position, another is relocatable
Dynamic roller 72, moves the flexible part 73 of axis connection of roller 72, and the driving of elastic component 73 moves roller 72 and presses to fixed roll 71.Elastic component 73 can be
Spring etc. passes through the cooperation of fixed roll 71 and dynamic roller 72, it can be ensured that when plank passes through, can receive stable pressure.Plate
The pressure value that material receives can adjust by adjusting the compression degree of elastic component 73.
The above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
