Abstract
The invention provides a special nylon heat shrinkage film with a high shrinkage rate, which belongs to the technical field of novel film materials. Compared with the prior art, the nylon heat shrinkage film is mainly made of polyamide, the heat shrinkage rate is as high as 50 to 100 percent, the high-shrinkage nylon film can be applied to food package and can also meet the special requirements on air blowing forming in composite material industry, the shrinkage rate is two to four times of 15 to 30 percent of the nylon heat shrinkage film in the prior art, the limitation of 15 to 30 percent of the nylon heat shrinkage rate is broken through, simultaneously, the toughness of the high-shrinkage nylon film is better, the anti-impact intensity is far ahead, the high-shrinkage nylon film can be more anastomotic with the special shape of a mandrel in the application of the composite material molding pressing forming mandrel, the special design is not needed, the perfect pasting can be realized only through easily heating the film to the required temperature and maintaining the temperature for a period of time, and the problems of fracture and the like because the film is not pasted in the proper position are reduced.
Description
Technical field
The present invention relates to the film new material technology field, is a kind of special nylon heat-shrinkable film with high shrinkage.
Background technology
Development along with bicycle trade; The progress of carbon fiber bicycle is huge; Original technological design can't be satisfied special formed demand fully; The limit of the nylon percent thermal shrinkage of airduct is 15-30% in the prior art; Can't fit the fully already mandrel of singular configuration, have highly shrinkable can airduct become urgent need.
Summary of the invention
For solving existing defective of nylon wind pipe and problem in the prior art, a kind of built-in nylon heat-shrinkable film that fuses core technology that adopts is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: nylon heat-shrinkable film of the present invention is mainly processed by polymeric amide; Comprise PA6, PA6/66, PA6/12 and PA6/66/12; The nylon heat-shrinkable film adopts high-polymer molecular chain stretch orientation principle design, is the method moulding with the chilling typing; When superpolymer is in elastomeric state; To its stretch orientation; Then with the superpolymer quenching to second-order transition temperature, molecular orientation is freezed, when article being carried out in the wrapping process it is heated; Because molecular thermalmotion produces stress relaxation; Molecule recovers original state, produces to shrink, and nylon heat-shrinkable film product has high percent thermal shrinkage; Percent thermal shrinkage can reach 50-100%, is widely used in food product pack and composite material moulded forming core shaft field.
The invention has the beneficial effects as follows: compared with prior art; The percent thermal shrinkage of nylon heat-shrinkable film of the present invention is up to 50-100%; The high nylon membrane that shrinks can not only be applied to food product pack; Also satisfy simultaneously the specific demand of composite industry blowing moulding; Be two to four times of nylon heat-shrinkable film 15-30% in the prior art; Broken through the restriction of nylon percent thermal shrinkage 15-30%; Simultaneously; The high nylon membrane toughness of shrinking is better; Resistance to impact shock is significantly leading; In composite material moulded forming core shaft is used; High can coincide the more singular configuration of mandrel of nylon membrane that shrinks need not special particular design, need easily be heated to temperature required and keeps for some time; Can perfect fit, reduced film because of the problem such as break that produces not in place of fitting.
Embodiment
Nylon heat-shrinkable film of the present invention is mainly processed by polyamide material; It comprises the materials such as PA6, PA6/66, PA6/12 and PA6/66/12 in the polymeric amide; PA6/66 is the blend composition of PA6 and PA66; PA6/12 is the blend composition of PA6 and PA12, and PA6/66/12 is the blend composition of PA6, PA66 and PA12.The nylon heat-shrinkable film adopts high-polymer molecular chain stretch orientation principle design, is the method moulding with the chilling typing; When superpolymer is in elastomeric state; To its stretch orientation; Then with the superpolymer quenching to second-order transition temperature; Molecular orientation is freezed; When article being carried out in the wrapping process it is heated; Because molecular thermalmotion produces stress relaxation; Molecule recovers original state; Produce and shrink, nylon heat-shrinkable film product has high percent thermal shrinkage, and percent thermal shrinkage can reach 50-100%; Broken through the restriction of prior art nylon percent thermal shrinkage 15-30%; Owing to percent thermal shrinkage with 100%, therefore can satisfy the mandrel of various singular configurations, be widely used in food product pack and composite material moulded forming core shaft field.
Compared with prior art; The percent thermal shrinkage of nylon heat-shrinkable film of the present invention is up to 50-100%; The high nylon membrane that shrinks can not only be applied to food product pack; Also satisfy simultaneously the specific demand of composite industry blowing moulding; Be two to four times of nylon heat-shrinkable film 15-30% in the prior art; Simultaneously; The high nylon membrane toughness of shrinking is better; Resistance to impact shock is significantly leading, in composite material moulded forming core shaft is used, and high can coincide the more singular configuration of mandrel of nylon membrane that shrinks; Need not special particular design; Only need easily be heated to temperature required and keep for some time, can perfectly fit, reduce film because of the problem such as break that produces not in place of fitting.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection domain that limits claim that those skilled in the art can make change and/or revise.
Claims (4)
1. a nylon heat-shrinkable film is mainly processed by polymeric amide, comprises PA6, PA6/66, PA6/12 and PA6/66/12.
2. nylon heat-shrinkable film according to claim 1 is characterized in that, described nylon heat-shrinkable film adopts high-polymer molecular chain stretch orientation principle design, is the method moulding with the chilling typing; When superpolymer is in elastomeric state, to its stretch orientation, then with the superpolymer quenching to second-order transition temperature; Molecular orientation is freezed, when article being carried out in the wrapping process it is heated, because molecular thermalmotion produces stress relaxation; Molecule recovers original state, produces to shrink.
