Abstract
A coating technology for increasing the binding fasteness of the second basic material during the extruding-out of a sandwich material features that before extruding, the decoiled film material is coated and dried, resulting in its high binding fasteness after extruded.
Description
One, technical field
The present invention relates to belong to a kind of extrusion composite technology of plastic compound flexible packaging industry.
Two, background technology
At present extrude the extruding in the combined producing tech of equipment complex in what compound package material was extruded in manufacturing in the plastic compound flexible packaging sector application, common first base material unreels to extruding has the coating drying function between compound, can guarantee that like this various plastic sheetings that first base material unreels are at the bonding intensity of extruding in compound.But, in extruding of sandwich material is compound, because it is narrow and small to extrude the frame for movement space of equipment complex, always be that the coating materials that unreeled by second base material without coating and directly extrudes compoundly with extruding tunic PE, this has just produced the outstanding defective of following two aspects: one be the coating materials that unreels of second base material with extrude that the compound fastness of tunic PE is poor, a little less than the bonding force.For example: produce certain polarity through high-temperature oxydation though extrude tunic PE, yet, the CPE base material of same molecular only can bond, with other materials for example the degree of adhesion of BOPET, BOPA, CPP, M-CPP and M-PET etc. all be lower than 0.5N/15mm, even layering, can't satisfy the instructions for use of packaging material.Adopt existing production technology second base material coating materials and extrude a little less than the bonding force of tunic PE because BOPET, BOPA, CPP, M-CPP and M-PET and extrude tunic PE and do not have affinity because of molecule is different, the CPE base material of the same molecular that still bonds only; Two is that the coating materials kind that unreels of second base material is few, the 0.7N/15mm that has only the bonding strength of CPE can be up to state standards and require at present, for example BOPET, BOPA, CPP, M-CPP and M-PET do not reach national standard to also have other second a lot of base materials, that is to say the narrow range of selecting materials of second base material, the CPE base material is only arranged.
Three, summary of the invention
The objective of the invention is to provide a kind of equipment complex of extruding of extruding compound package material that is applied to make, extruding the coating process that improves the compound fastness of second base material in compound, thereby overcoming existing production technology exists coating materials that second base material unreels and extrudes a little less than compound fastness difference of tunic PE and the bonding force, and the selection material range of second base material is narrow and can not use BOPET, BOPA, CPP, M-CPP and M-PET, cause being difficult to adapting to the drawback of the use needs of various packaging material.
The object of the present invention is achieved like this: of the present inventionly extruding the coating process that improves the compound fastness of second base material in compound, be applied to extrude equipment complex, it is in extruding of sandwich material is compound, in order to extrude Compound Machining to base material with various characteristics, so that can satisfy more packaging material instructions for use, the coating materials that second base material unreels increases the coating drying function before compound entering to extrude.Like this, for also just being readily solved, not only having solved the problem a little less than the sandwich material bonding force but also enlarged the scope of selecting for use of second base material because of the problem a little less than the different institute of the molecular structure of the material bonding force that causes.For example, the base material film of the top BOPET that mentions, BOPA, CPP, M-CPP and M-PET etc. all is greatly enhanced with the bonding force of extruding tunic PE, all reach more than the 0.7N/15mm, the highest can reach 2N/15mm, thereby can satisfy the instructions for use of various packaging material fully.
Because the coating materials that unreels of second base material has increased the coating drying function with extruding between the tunic PE, so extruding compound production equipment has just had more wide use, application prospect broadness more in the plastic compound flexible packaging industry.The plastic compound flexible packaging manufacturing enterprise of equipment complex is extruded in use, and application the present invention can produce multilayer and extrude compound packaging material according to the various demands in market.
Four, description of drawings
Fig. 1, be process schematic representation of the present invention.
Five, the specific embodiment
Below in conjunction with drawings and Examples know-why of the present invention is further described:
The present invention is applied to make the equipment complex of extruding of extruding compound package material, it is in extruding of sandwich material is compound, in order to extrude Compound Machining to base material with various characteristics, so that can satisfy more packaging material instructions for use, the coating materials that second base material unreels increases the coating drying function before compound entering to extrude, thereby make coating materials that second base material unreels and extrude tunic PE and obtain the compound of stronger compound fastness, increase the bonding force between it, guarantee not stratified, like this, ensured that multilayer extrudes the quality of joint product.Coating drying function described herein is realized by following measure: second base material the compound chill roll side from extrude equipment complex enter extrude compound before, mode with the applicator roll coating, glue or other jointing material that will have adhesive effect are uniformly coated on the surface of second base material, then, the hot blast that baking oven produced that utilization is extruded in the equipment complex is dried second substrate surface that is coated with, like this, the coating materials of second base material with extrude tunic PE and extrude and can obtain the bonding firm compound package material of extruding after compound.
Particularly, in Fig. 1, the present invention is in unreel (1) of carrying out first base material, silica gel roller side from extrude equipment complex enter extrude compound, through coating (2), oven dry (3), the coating materials of first base material with extrude tunic PE (4) and extrude compound the time by chill roll (5) and silica gel roller (6), carry out unreel (7) of second base material, compound chill roll side from extrude equipment complex enter extrude compound, through coating (10), oven dry (9), the coating materials of second base material is extruded compoundly with extruding tunic PE (4) by chill roll (5) and silica gel roller (6), extrude compound package material thereby obtain bonding firm three layers.At last, by wrap-up (8) extruding compound package material is carried out rolling.
Equally, use invented technology like this just can produce to satisfy on the market multilayer more than three layers of various Different Package materials demands to extrude compound package material.
Below enumerate embodiment the present invention remake statement:
Embodiment one: manufacturing is used for packaged food and fresh-keeping laminated film of having relatively high expectations: selecting PET and M-PET at first respectively for use is first, second base material, with AC is coating glue or other jointing material, then, carry out unreel (1) of first base material, silica gel roller side from extrude equipment complex enter extrude compound, through coating (2), oven dry (3), the coating materials of first base material with extrude tunic PE (4) and extrude compound by chill roll (5) and silica gel roller (6), meanwhile, carry out unreel (7) of second base material, compound chill roll side from extrude equipment complex enter extrude compound, through coating (10), oven dry (9), the coating materials of second base material with extrude tunic PE (4) extrude by chill roll (5) and silica gel roller (6) compound, thereby obtain bonding firm packaging material for food.
