Description
Technical field
The present invention relates to a kind of TPU processing technologys, specifically, designing a kind of waterproof and breathable TPU film processing technology.
Background technique
The entitled thermoplastic polyurethane elastomer rubber of TPU is a kind of novel organic polymer synthetic material, can replace
For rubber or soft polyvinyl chloride material, good wearability, resilience is superior to conventional polyurethanes, and ageing-resistant performance is better than
Rubber, it may be said that TPU is the optimal material for substituting PVC and PU, is known as novel polymer material in the world.Its molecule
Structure is that the hard block obtained by diisocyanate and chain extender reaction and diisocyanate are reacted with macromolecular polyol
What obtained soft segment was alternately constituted.TPU has brilliant high-tension, high-tensile strength, tough and anti-aging property, answers extensively
For health care, electronic apparatus and sports goods etc..
TPU film is most widely used garment industry, is mainly used for being compounded in web surface as wind and water preventing layer,
Traditional TPU film surface compact has good wind and water preventing effect, but gas permeability is longer, and wearer can be allowed to feel sultry,
Be not suitable for long-term dress.
Summary of the invention
Goal of the invention: present invention aims in view of the deficiencies of the prior art, provide a kind of waterproof and breathable TPU film processing
Technique.
A kind of technical solution: waterproof and breathable TPU film processing technology of the present invention, comprising the following steps:
1) the melt-blown head point column that four bores are 30~50mm are chosen and are mounted on the rack composition spinneret complete machine；
2) it is meltblown on head and is connected with four-way translation mechanism and is connected on the rack by four-way translation mechanism；
3) temperature control heating device is set at melt-blown head, by the adjustable setting of molten nozzle temperature at 130~180 DEG C；
4) through carrying out spinneret operation by melt-blown head after taking polyurethane TPU master batch is modified to melt, melt-blown head is handed in spinning process
For carry out front and back to left and right to translation, reciprocal spinneret is carried out with this；
5) the network-like TPU after the completion of spinneret is gently pressed into membranaceous through chill roll；
6) TPU membrane for being pressed into film dress is transformed into uniform film through hot-pressing roller heavy calendered multiple.
Preferably, first reciprocal spinneret 5~10 times of front and back of melt-blown head, then left and right is reciprocal when carrying out spinneret in step 4
Spinneret 5~10 times.
Preferably, the polyurethane master batch used in step 4 is the modified polyurethane master batch of hardness 80%.
Preferably, the temperature setting of chill roll is 0~6 DEG C in step 5.
Preferably, the hot-pressing roller in step 6 is infrared ray wave band hot-pressing roller.
Preferably, the temperature setting of the infrared ray wave band hot-pressing roller is 80~100 DEG C.
Preferably, the weight operation in step 6 is reciprocal weight 2 times.
The present invention has the advantages that (1) using multipoint mode meltblown, production efficiency and production compared with the prior art
It can all be significantly increased；
(2) using bore is the spout of 30~50mm as melt-blown head, and spinneret is thinner, and the TPU film structure produced is more
Densification, waterproof performance is more preferable, and more preferably with spinneret temperature and the suitability of pressure；
(3) spinneret is carried out in the method for the reciprocal spinneret of four-way, so that compacting, which forms film, is laminated acquisition by reticular structure, thus
So that having alternate gap in length and breadth in film, also have under the premise of mutual closing guarantees good waterproof performance good
Gas performance；
(4) the press mold operation that hot-pressing roller weight after first chill roll is gently pressed is carried out after the completion of spinneret, so that TPU film obtained
Thickness is uniform, and elasticity is more preferable.
Specific embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
A kind of waterproof and breathable TPU film processing technology, comprising the following steps:
1) the melt-blown head point column that four bores are 30~50mm are chosen and are mounted on the rack composition spinneret complete machine；
2) it is meltblown on head and is connected with four-way translation mechanism and is connected on the rack by four-way translation mechanism；
3) temperature control heating device is set at melt-blown head, by the adjustable setting of molten nozzle temperature at 130~180 DEG C；
4) through carrying out spinneret operation, spinneret by melt-blown head after taking the modified polyurethane TPU master batch of hardness 80% is modified to melt
In the process melt-blown head alternately front and back to left and right to translation, reciprocal spinneret is carried out with this；
5) the network-like TPU after the completion of spinneret is gently pressed into membranaceous through 0~6 DEG C of chill roll；
6) TPU membrane for being pressed into film dress is extended through 80~100 DEG C of infrared ray wave band hot-pressing roller weight 2 times into uniform film.
The advantages of invention, is (1) using multipoint mode meltblown, and production efficiency and production capacity are all significantly increased；
(2) using bore is the spout of 30~50mm as melt-blown head, and spinneret is thinner, and the TPU film structure produced is more
Densification, waterproof performance is more preferable, and more preferably with spinneret temperature and the suitability of pressure；
(3) spinneret is carried out in the method for the reciprocal spinneret of four-way, so that compacting, which forms film, is laminated acquisition by reticular structure, thus
So that having alternate gap in length and breadth in film, also have under the premise of mutual closing guarantees good waterproof performance good
Gas performance；
(4) the press mold operation that hot-pressing roller weight after first chill roll is gently pressed is carried out after the completion of spinneret, so that TPU film obtained
Thickness is uniform, and elasticity is more preferable.
Use TPU breathable films made from this method that can be formed anti-to heat glue point patch composite chemical fibre cloth or interwoven
Water airing function fabric has while guaranteeing has good water proof wind proof performance using the TPU film as fabric outer layer
Have excellent permeability, solve the traditional sultry drawback of the fabric, simultaneously as in network TPU gap presence, this
Kind of TPU breathable films have good dyeability, can print and dye more colors as garment material, more beautiful.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
Various changes can be made in the form and details for it.
