Description
Technical field
It is especially a kind of to be applied on foam sheet the present invention relates to a kind of production method of foam sheet surface film
Spoon a kind of and film of foam sheet same material production method.
Background technology
Foam sheet refers to that its thickness is usually 1.5-3mm applied to the foamed plastics used in plastic thermoforming product；
Foamed plastics has the advantages that light, heat-insulated, buffering, insulation, anti-corrosion, cheap, therefore in commodity, packaging, industry, agriculture
Industry, transportation, war industry, aerospace industry are used widely, the hair of foamed plastics since China the 1990s
Exhibition is very rapid, wherein principal item have that polyurethane (PU) is soft and rigid foam, polystyrene (PS) foamed plastics and
Polyethylene (PE) foamed plastics three major types.The most foam sheet of application includes PS foaming, PP foaming, PET foaming now.Do not drench
The foam sheet rough surface of film, it is difficult to overlay film.
At present, the raw material applied to the disposable noodle bowl of making, plastics mess-tin use PP polypropylene materials mostly, and PP gathers
The plastic products such as propylene material is by extruding, the noodle bowl that thermoforming is fabricated to, mess-tin.But the material is more crisp, toughness is poor,
Its bend resistance and tear ability are poor, are easily broken.It is generally in foam sheet overlying to solve the problem
Film.The process of overlay film is at present：A layer of adhesive is first coated with foam sheet, then adhesive is dried, then in foamed sheet
Material overlying unifies layer film, finally carries out hot-forming.This coating processes it is complicated, step is relatively more, laminating effect
It is bad, buy in addition and also need to expend an expense when producing adhesive, production cost is very high, is unable to reach the mesh of energy-conserving and environment-protective
's.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of production method of foam sheet surface film, this foamed sheet
The production method of material surface film can be in one layer of reinforcement film laminating directly on a surface of foam sheet, and laminating effect is more preferable,
Structure is simpler, more energy-conserving and environment-protective.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is as follows：
A kind of production method of foam sheet surface film, it is characterized in that：Comprise the following steps：
Step 1：Using the coating mechanism including laminating pressure roller and laminating fixed roll, laminating pressure roller and laminating fixed roll are arranged side by side, and cover
Gap is provided between combined pressure roller and laminating fixed roll；
Step 2：Foam sheet is released between laminating pressure roller and laminating fixed roll by foam sheet unreeling structure；
Step 3：The mould mouth of thin film extruding machine structure is disposed proximate to the gap between laminating pressure roller and laminating fixed roll, film extrusion
Mechanism directly extrudes film on laminating pressure roller；
Step 4：Drive laminating pressure roller to rotate, directly cover the freshly extruded film with higher residual temperature under the cooperation of laminating fixed roll
Close on foam sheet surface.
In the above method, the gap of the mould mouth of thin film extruding machine structure between laminating pressure roller and laminating fixed roll, breach
Traditionally using adhesive is laminating and the normal mode of hot pressing cladding, make film fully viscous using the residual temperature on freshly extruded film
It is attached on foam sheet surface so that the film of the mould mouth extrusion of extrusion die can be carried out before uncolled with foam sheet
It is directly laminating, it can be good at controlling extrusion film to be adhered on foam sheet surface.Film and foam sheet progress are laminating, this
In using laminating pressure roller and laminating fixed roll suppress laminating, the complete of film and foam sheet is realized by the pressure of laminating pressure roller
It is complete laminating；Because the material of the film is identical with the material that foam sheet uses, when by laminating pressure roller, due to just squeezing
The film temperature gone out is higher, and surface-active is far above the surface-active that is heated of cold film, when laminating, film and foaming
Sheet material interpenetrates, and forms the tack coat of densification so that the combination between film and foam sheet is closer, than glue bonding more
Closely, it need not add any adhesive and solvent, and without processes such as coating adhesive, drying and hot pressing, laminating effect is more
Good, structure is simpler, more energy-conserving and environment-protective.
As the preferred scheme of the present invention, the temperature range of the freshly extruded film with higher residual temperature is in the step 4
120-150℃。
As the preferred scheme of the present invention, the production method of foam sheet surface film is drenched using following foam sheet

Between the piston-rod end and towing bracket that press cylinder, second carry-over pinch rolls are installed in rotation on towing bracket.It is logical
Such setting is crossed, when the up and down motion of traction pressing cylinder, drives the second carry-over pinch rolls to transport up and down by towing bracket
It is dynamic.When traction pressing cylinder moves downward, the second carry-over pinch rolls are driven to decline, the second carry-over pinch rolls are applied to the surface of the first carry-over pinch rolls
Add a pressure so that after the foam sheet stress through the first carry-over pinch rolls and the second carry-over pinch rolls stretches, be drawn into
Rolling-up mechanism, more preferable winding effect is played to foam sheet, and draw pressing cylinder spring in bonding processes play it is slow
Punching acts on, and ensures that caused pressure is appropriate between the first carry-over pinch rolls and the second carry-over pinch rolls.
As the preferred scheme of the present invention, the rolling-up mechanism includes Scroll and winding motor, and the Scroll can turn
It is arranged on dynamicly in frame, output shaft and the winding axis connection of the winding motor.By this set, winding motor, which drives, to be received
Spool realizes the winding to the foam sheet after film, while winding power caused by winding motor is also the leaching of foam sheet surface
The traction power of film device；Foam sheet after film is transported on Scroll by haulage gear, and sheet material wound on receipts
On spool, the production process of whole foam sheet film is completed.
The present invention compared with prior art, has the following advantages that：
The production method of this foam sheet surface film is breached traditionally using adhesive is laminating and the routine of hot pressing cladding
Pattern, film is allowed fully to be adhered on foam sheet surface using the residual temperature on freshly extruded film so that the mould of extrusion die
The film of mouth extrusion can be directly laminating with foam sheet progress before uncolled, can be good at controlling extrusion film adhesion
On foam sheet surface.Because the material of the film is identical with the material that foam sheet uses, by laminating pressure roller when
Wait, because freshly extruded film temperature is higher, and surface-active is far above the surface-active that cold film is heated, laminating
When, film interpenetrates with foam sheet, forms the tack coat of densification so that the combination between film and foam sheet is tighter
Close, closer than glue bonding, it need not add any adhesive and solvent, without coating adhesive, drying and hot pressing etc.
Process, laminating effect is more preferable, and structure is simpler, more energy-conserving and environment-protective.
