Abstract
The present invention relates to saturating waterproof membrane production technical field in new TP U, particularly relate to a kind of novel curtain coating and batch middle permeation waterproof humidity-permeant TPU membrane.A kind of novel curtain coating of the present invention batches the product of middle permeation waterproof humidity-permeant TPU membrane, and it comprises selects, by adding new TPU pellet of filling a prescription after high-temperature fusion, to extrude---cool---shaping---batching from extruder die head.It comprises die head, and it also comprises the decorative pattern shaping wheel, shaping cooling wheel, the driving wheel that are arranged under extruder die head, also comprises rubber expanding wheel, rolling driving wheel, static elimination wheel, anti-skidding Teflon and wrap-up.The present invention fills a prescription uniqueness, novelty, to breach in other permeation waterproof humidity-permeant film must blowing, attached PE just fertile limitation, allow the more convenient operation of postorder, reduce the dual waste of polyethylene and thermoplastic polyurethane, cost-saving, improve the quality of products.
Description
Technical field
The invention belongs to TPU field of new, particularly relate to a kind of novel middle permeation waterproof humidity-permeant TPU membrane new product.
Background technology
TPU (thermoplastic polyurethane) is environmental protection macromolecule polymer, which overcome many defects of PVC and PU film, not only have most of characteristic of rubber and common plastics, but also have excellent comprehensive physical and chemical property, so the following material that is otherwise known as.In TPU, permeation waterproof humidity-permeant film adopts TPU pellet, and the film made by special process, it inherits the outstanding physical property of TPU, and range of application is very extensive.Owing to having avirulent advantage, meet environmental requirement, in TPU, permeation waterproof humidity-permeant film product is widely used in the fields such as high-grade clothing, footwear material, blowing bag, packaging and handicraft.
Summary of the invention
The object of this invention is to provide permeation waterproof humidity-permeant TPU membrane in one, this waterproof humidity-permeant film adopts TPU particle through extruder die head, the TPU melt of thickness between 0.01mm-0.10mm is attached to rapidly the cooling wheel surface of low temperature, melt is cooled fast and forms transparent or cloudy surface or coloured TPU film.This product not only maintains the original good characteristic of TPU, and adds new function, and waterproof, gas permeability are splendid.
Middle permeation waterproof humidity-permeant TPU membrane key property of the present invention shows:
1, film thickness: 0.01mm ~ 0.10mm;
2, with reference to GB/T4744-1984 standard, utilize YG812 type water tester, record film more than water pressure resistance 10000mmH25;
3, with reference to GB/T12704-91B standard, the method for executing is utilized to record between the moisture permeability 8500 ~ 10000g/m2*24hrs of film.
The production technology spy that described a kind of curtain coating batches middle permeation waterproof humidity-permeant TPU membrane is: the temperature first setting die head, and when after the temperature that extruder die head reaches set, die head is started working.Now, extruder by TPU pellet by die head heating, flow out-cooling-shaping-batch after melting.
Described process conditions are: die head temperature 80 ~ 250 DEG C; Curtain coating speed 2 ~ 300m/min; TPU casting temperature 80 ~ 250 DEG C; Thickness 0.01 ~ the 0.10mm of TPU membrane; Coiling speed 2 ~ 300m/min; Electric current 20 ~ 140A.
Distinguishing feature of the present invention is: the method adopting high temperature curtain coating, will form permeation waterproof humidity-permeant TPU film in individual layer, without the need to attached PE or other film after TPU melting.
Present invention process is unique, simple, breach permeation waterproof humidity-permeant film in other and must use blowing, attached PE just fertile limitation, allow the more convenient operation of postorder, reduce the dual waste of polyethylene and thermoplastic polyurethane, cost-saving, and product environment-protecting asepsis, waterproof, permeability are fabulous, wear-resisting, heat-resisting, be the optimal material making high-grade dress ornament, footwear, packaging, water sport items.
Detailed description of the invention.Described production curtain coating batches middle permeation waterproof humidity-permeant TPU membrane step:
First set the temperature of extruder die head, when after the temperature that extruder die head reaches set, die head is started working, by TPU pellet by extruder die head heating, flow out-cooling-shaping-batch after melting.
Described process conditions are: extruder die head temperature 80 ~ 250 DEG C; Curtain coating speed 2 ~ 300m/min; TPU casting temperature 80 ~ 250 DEG C; Thickness 0.01 ~ the 0.10mm of TPU membrane; Coiling speed 2 ~ 300m/min; Electric current 20 ~ 140A.
The each group of formula of raw material of described novel middle permeation waterproof humidity-permeant TPU membrane is: TPU pellet: 30 ~ 95Phr; Interior lubrication prescription: 0.1 ~ 60Phr; Outer lubrication prescription: 0.1 ~ 70Phr; Antioxidant: 0.01 ~ 10Phr; UV resistant agent: 0.01 ~ 10Phr.
Described interior lubrication prescription is SA, ethylidene benzoic acid glycerine alcohol ester, and its effect can increase thin smooth, brightness when estimating shaping.
Described outer lubrication prescription adipic acid pentaerythritol ester, its effect reduces film viscosity when take-up, to ensure that the top layer of film is bright and clean, smooth, convenient processing.
Claims (1)
1. in, a production method for permeation waterproof humidity-permeant TPU membrane, is characterized in that, the composition of raw materials of described middle permeation waterproof humidity-permeant TPU membrane is: TPU pellet: 30 ~ 95Phr; Interior lubrication prescription: 0.1 ~ 60Phr; Outer lubrication prescription: 0.1 ~ 70Phr; Antioxidant: 0.01 ~ 10Phr; UV resistant agent: 0.01 ~ 10Phr; Wherein said TPU pellet is TPUE, and described interior lubrication prescription is SA, ethylidene benzoic acid glycerine alcohol ester, and described outer lubrication prescription is adipic acid pentaerythritol ester;
