Abstract
The present invention discloses ultraviolet light solidification scratch resistance selfreparing TPU stealth film and preparation method thereof.The film under ultraviolet light irradiation condition can rapid curing film forming; film forming coatings have excellent adhesion strength; it simultaneously being capable of multiple self-regeneration under damaged or failure condition; and there is excellent yellowing resistance, water resistance, anti-ultraviolet property; play the role of protecting car surface paint layer; good combination property is conducive to wide popularization and application.
Description
Technical field
The invention belongs to the ultraviolet light solidification of protective film, protective coating technique field, in particular to car surface protection is anti-
Scratch selfreparing TPU stealth film and preparation method.
Background technique
China reforms and opens up to the outside world 40 years, and along with the high speed development of national economy, the wealth of the public common people has also been obtained significantly
Accumulation, while the centrality of movement of population also leads to being obviously improved for the urban development population degree of crowding.Originally at high price
Automobile can obtain the favor of wealth accumulation family, and easily highway construction is but also automobile family oriented is quickly pushed away in China
Into.Currently, the vehicle paint of the high-tech level of the automobile and its carrying high relative to external price is protected, domestic automobile price is more
Add cheap, thus is more suitable for carrying out the Chinese family of wealth accumulation, however the vehicle paint of additional low technical therewith, in reality
In use process, facing to severe natural environments such as sandstorm, acid rain, hazes, surface vehicle paint is easy to impaired rupture.Tradition
Mode be to be waxed car body surface, seal glaze and plating is brilliant.Nowadays with the development of technology, a kind of novel protected mode,
I.e. in car body surface fitting or spraying paint surface protective film, also known as invisible vehicle cover, the favor of driving personage is gradually obtained.Compared to
Traditional approach, invisible vehicle cover belong to pure physics defence, can keep out wind and rain, and service life is long, exempt the regular vehicle face dimension of driving family
The trouble of shield.
Traditional car clothing film mainly solves the problems, such as the environmental nuisance faced in automobile use process, such as burning sun is exposed to the sun, acid
Rain burn into sandstorm scraping etc. is effectively prevented the breakage of automobile coating by physics mode protection, automobile is existed
Honorable color and bright and clean surface are kept in for a long time.However there are disposable problems for the use of most of car clothing film, once
Car clothing film is damaged or scratches, and damaged part just loses original protective effect, and become leads to entire vehicle body car clothing film over time
The disappearance of physics defense function.Therefore in order to promote the service life of car clothing film, the emphasis of a research and development is to improve car clothing film
Resisting breakage or scratch resistance capability.The patent of invention and a Patent No. of one Patent No. CN201110307234.7
The patent of invention of CN201510563327.4 is by adding micro-nano granules in car clothing film, to be obviously improved car clothing film
Service performance, extend defence the period.The main feature of both patents is, due to the addition of micro-and nano-particles, leads to vehicle
Opaque state is necessarily presented in clothing film, that is, cannot achieve the stealthy of car clothing film and require (film is transparent).This is for pursuing genuine original paint
For the car owner for showing effect, heart will necessarily generate this car clothing film and contradict psychology.Prior problem is even if mentioning
Service life is risen, however the damaged disposable problem of bring still can carry out defect to the protection band of automobile coating.
Self-repair material is one of the hot spot of 21 century high molecular material research and development.Using polymer material self-healing or from
Characteristic is repaired, the coating i.e. service life of membrane material can be effectively promoted.Among these, polyurethane material is since its is special hard
Section and soft segment structure, so that coating, which under damaged or crack conditions, can be crossed, realizes moving for active segment in damaged face or the plane of disruption
Shifting movement has important research and application prospect to realize self i.e. selfreparing of healing of material.However polyurethane coating
Anti-yellowing property selfreparing car clothing film that is poor, therefore being prepared using polyurethane material as main base, inevitably occur
Yellowing.In order to promote the yellowing resistance of polyurethane material, use aliphatic isocyanates synthesis of polyurethane performed polymer more.Together
When polyurethane material cure cycle it is long, will lead to car clothing film production cycle extend, increase the production cost of product.
Summary of the invention
It is an object of that present invention to provide one kind to have both excellent with quick-setting invisible vehicle cover membrane coat, the car clothing membrane coat
Different adhesion strength and self-healing properties, while the cure cycle of car clothing membrane coat is greatly reduced, it can be applied to all kinds of vapour
Surface of vehicle paint, comprehensive performance is good, and protecting effect is good.
