Abstract
The invention relates to the field of fine chemical products, in particular to a producing method of double-layer composition of plastic film sheet on a plastic film blowing machine. The invention pertains to a plastic film sheet, the compositions of which are 5-65 percent of low density polyethylene and 95-35 percent of acetic acid. Difference of the producing method of the invention with the existing plastic film is that: the temperature of a die head of the plastic film blowing machine is 150 to 170 DEG C, which causes that the plastic film blown in drum shape can be directly compacted into bundles without cutting, namely, two layers of film are hot pressed into one layer. The invention has the advantages that: the tenderness of the plastic film is increased by changing the compoundingformula of the plastic film, and the viscidity of the film is also increased by enhancing the temperature of the die head; the originally separated two layers of film are closely compacted into a whole; due to the invention, the modification to the existing device is little, and the production cost is lowered. By using a small scale device for producing thick plastic film sheet, machine consumptions in production process can also be reduced and the cost is prevented from increasing due to the composing by glue and environment pollution.
Description
Technical field
The present invention relates to a kind of fine chemical product field, especially belong to the making method and the equipment thereof of a kind of plastic film sheet material two-layer compound on inflation film manufacturing machine.
Background technology
Figure 1 shows that existing blow moulding machine theory structure synoptic diagram, it is to drive screw rod 2 motions by motor 1 by wheel box 11, raw material enters screw rod 2 from hopper 21, pulverize by the heating of heating unit 3 and the extruding of screw rod 2, raw material enters die head 23 (temperature in the die head is generally about 120 degree) through ring flange 22 (in have filter screen impurity can be removed) and forms plastics film, blow out tubbiness through wind dish 24, flatten through sheerleg 5, behind take off roll 6 (generally forming) by an iron roller and a root rubber roller, by many transition rollers 61 guiding, one group of two folder rod 64 (generally also being made up of an iron roller and a root rubber roller) arranged by driven by motor below knife rest 7, motion-promotion force as plastics film, plastics film both sides behind knife rest 7 are cut by blade under it drags, and drive two wind-up rolls 8 respectively by winding motor 81 and are rolled into bundle respectively.Existing screw diameter is that generally can only to produce thickness be that 0.3mm, width are the film of 70cm to the blow moulding machine of 75mm.The sealing membrane of arrangements for automotive doors needs softness and thickness requirement to reach 0.56mm at present; and will produce thickness is that the plastic film of 0.56mm will use screw diameter to strengthen the extrusion capacity of plastics as the blow moulding machine of 120-130mm; simultaneously various relevant devices are as wheel box; motor; heating installation; the screw rod equal-volume; power; intensity all will be multiplied; cause the big price height of whole plant thus; floor space is big; increase production cost; simultaneously because film thickness is thick; knife rest 7 stressed increases; blade abrasion is serious; blade; knife rest is flexible; fracture; need often to change; change blade if shut down; knife rest, the ordering parameter of starting shooting again will produce 100 kilograms waste product usually to ordinary production; if do not shut down tool changing; then require workman's state of the art height, and also all will produce waste product in tool changing and the blade adjustment process, this has directly increased production cost.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the existing production technique, provide that a kind of to produce width on existing blow moulding machine constant, the making method and the equipment of the plastic film sheet material that thickness is multiplied two-layer compound on inflation film manufacturing machine.
The present invention is a kind of plastic film sheet material, its multipolymer 95-35% that consists of new LDPE (film grade) 5-65%, ethylene/vinyl acetate.Be preferably the multipolymer 85-65% of new LDPE (film grade) 15-35%, ethylene/vinyl acetate.
The difference of its making method and existing plastic film is, the die head temperature height of blow moulding machine is the 150-170 degree, the plastic film that will blow round barrel shape is rolled into bundle without the direct compacting of cutting, the promptly two-layer one deck that is combined into, and the temperature that improves die head is in order to improve the viscosity of plastic film.
The present invention improves equipment: cancellation tool holder system and a wind-up roll on the basis of existing blow moulding machine, only keep a wind-up roll, take off roll front end at blow moulding machine is equipped with heating unit simultaneously, Heating temperature is the 120-150 degree, turn the gap between two rollers of take off roll down, the size in concrete gap is decided by the thickness of required plastics sheet.Also can on the take off roll of blow moulding machine reheater be housed, Heating temperature is the 150-170 degree, also can directly be added in heating unit on the irony take off roll.According to the different requirements of plastic film sheet material, also can improve two folder rods: or cancellation need not, or turn its gap down even increase heater block (similar) and heat again, so that plastic film sheet material is compressed again to take off roll.
Advantage of the present invention is: the pliability that increases plastic film by the prescription that changes plastic film, changed production method simultaneously, improving die head temperature is in order to increase the viscosity of plastic film, original plastic film that separates compressed make two-layer being integrated, under situation to the little change of existing installation, produce the plastic film that thickness is multiplied, need not cutting, so do not have the waste product that causes because of the tool holder system fault, reduced production cost.Utilize bantam to make thick plastic film sheet material, also saved the machine consumption in the production process, also avoided increasing and problem of environmental pollution with the compound cost that brings of glue.
