Abstract
The invention discloses a kind of regenerative PET bottle sheet and regeneration LDPE alloy production multi-layer co-extruded film PP Pipe Compound, be made up of following component: regenerative PET bottle sheet 60 85 weight portion, regeneration LDPE feed back particle, EVA 3 15 weight portion, grafting POE 3 10 weight portion, oxidation PE wax 0.1 0.5 weight portion, PPA 0.1 0.2 weight portion, GMS 0.1 0.3 weight portion and chain extender PMDA 0.1 0.3 weight portion.The present invention solves the phenomenons such as regenerated plastics extrusion film tear and rupture of membranes, can partly substitute virgin material PET and PE alloy.
Description
Technical field
The present invention relates to a kind of regenerative PET bottle sheet and regeneration LDPE alloy production multi-layer co-extruded film PP Pipe Compound and preparation thereof
Method.
Background technology
PET and PE virgin material alloy is the most relatively conventional, is mainly used in many stringcourses and squeezes above film, but price is still held high
Expensive, market produces multi-layer co-extruded film PP Pipe Compound currently without appearance regenerative PET and regeneration PE alloy production multilayer.
Because regeneration feed back also has other incompatible other kind plastics and solid impurities, easily go out when causing extrusion film
Existing Film Tear, cut is difficult to be molded or yield rate is extremely low, and general yield rate 20% is once；Material degradation molecular weight distribution becomes
Width, processing difficulties.
Summary of the invention
An object of the present invention is that a kind of regenerative PET bottle sheet of offer is multi-layer co-extruded thin with regeneration LDPE alloy production
Film special material, this regenerative PET bottle sheet solves regenerated plastics extrusion with regeneration LDPE alloy production multi-layer co-extruded film PP Pipe Compound
The phenomenon such as Film Tear and rupture of membranes, can partly substitute virgin material PET and PE alloy.
Technical scheme is: a kind of regenerative PET bottle sheet and regeneration LDPE alloy production multi-layer co-extruded film PP Pipe Compound, by following
Composition is made: regenerative PET bottle sheet 60-85 weight portion, regeneration LDPE feed back particle, EVA 3-15 weight portion, grafting POE 3-10
Weight portion, oxidation PE wax 0.1-0.5 weight portion, PPA 0.1-0.2 weight portion, GMS 0.1-0.3 weight portion and chain extender PMDA
0.1-0.3 weight portion.
The two of the purpose of the present invention are to provide a kind of one to prepare above-mentioned regenerative PET bottle sheet and regeneration LDPE alloy production
The preparation method of multi-layer co-extruded film PP Pipe Compound.
Technical scheme is: it is special with the regeneration multi-layer co-extruded film of LDPE alloy production that one prepares above-mentioned regenerative PET bottle sheet
The preparation method of material, comprises the following steps:
Step one: select the regenerative PET bottle sheet of viscosity stabilization, selects regeneration LDPE feed back particle, through 120 mesh stainless steels
Screen pack；
Step 2: regenerative PET bottle sheet is dried process；
Step 3: take EVA, grafting POE, oxidation PE wax, PPA, GMS and chain extender PMDA, and step one and step
The regenerative PET bottle sheet that two handle well puts into high mixer, heating mix and blend 4 minutes together with regeneration LDPE feed back particle；
Step 4: extruding pelletization；
Step 5: homogenizing is dried to obtain product, packaging.
As preferably, in described step 2, baking temperature is 120 DEG C, and the time is 2 hours.
As preferably, in described step 4, extrusion temperature 190 ~ 245 DEG C.
As preferably, in described step 4, using three layer filtration net during extruding pelletization, ground floor 80 mesh stainless steel filters
Net, the second layer 120 mesh stainless steel filter screen, third layer 80 mesh stainless steel filter screen.
Inventive principle: in the present invention, EVA plays the effect of increase-volume in PET and LDPE, and grafting POE contains in formula
Trace other other increase-volumes of impurity plastics and peptizaitons, aoxidize lubrication in PE wax plays well in the middle of PET and LDPE,
Improving plasticizing capacity, PMDA plays raising molecular weight for PET degraded, makes molecular weight distribution more stable homogeneous, is beneficial to processing,
PPA and GMS improves plastic processing type and antifogging performance.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
Embodiment 1 regenerative PET bottle sheet and the preparation regenerating LDPE alloy production multi-layer co-extruded film PP Pipe Compound
Step one: select clean, regenerative PET bottle sheet 60 weight portion of free from admixture non-variegation, viscosity stabilization, selects free from admixture
Regeneration LDPE feed back particle 25 weight portion, through 120 mesh stainless steel filter screen.
Step 2: regenerative PET bottle sheet is dried process, baking temperature is 120 DEG C, and the time is 2 hours.
Step 3: take EVA 10 weight portion, grafting POE 5 weight portion, oxidation PE wax 0.3 weight portion, PPA 0.15 weight
Amount part, GMS 0.15 weight portion and chain extender PMDA 0.1 weight portion, and the regenerative PET bottle that step one is handled well with step 2
Sheet puts into high mixer, heating mix and blend 4 minutes together with regeneration LDPE feed back particle.
Step 4: extruding pelletization, extrusion temperature 190 ~ 245 DEG C, use three layer filtration net, ground floor 80 mesh during extruding pelletization
Stainless steel filter screen, the second layer 120 mesh stainless steel filter screen, third layer 80 mesh stainless steel filter screen.
Step 5: directly make into: be homogenized, be dried, pack.
By embodiment 1 in the film experiment produced by regenerative PET and regeneration LDPE alloy PP Pipe Compound, calendering extrusion is thin
Film thickness 0.5mm, width 1.2m, in calendering 20 meters of film samples of length, without white point, without drum, without tear phenomenon, existing without rupture of membranes
As, smooth in appearance is transparent, and intensity is more than PE film.Solve the phenomenons such as regenerated plastics extrusion film tear and rupture of membranes, can portion
Divide replacement virgin material PET and PE alloy.
