Description
Technical field
The present invention relates to a kind of multilayer film, particularly a kind of PP base material decorating film.
Background technology
Building film material material is the New Building Materials grown up from 20 century 70s, belong to the coated fabric in field of textiles, the 5th kind of construction material after iron and steel, cement, timber and glass, it can in the inconvenient field of existing building materials application, as or ultra-large type architectural use large-scale without pillar, be provided with the superiority that traditional building material is incomparable, expand the range of application of construction material.It has the moulding advantages such as lightly free, attractive in appearance, printing opacity, energy-saving and environmental protection, excellent fire resistance, anti-fouling and self-cleaning performance, safe life be long, is widely used in the buildings such as large-scale stadium, shopping field, show ground, entrance gallery, public place of entertainment, parking lot, plant sightseeing dome and gas station mainly as semipermanent construction material.Because 2008 Beijing Olympic Games stadiums " Bird's Nest " etc. successfully build up and come into operation, and the holding of the international distinguished gathering such as Shanghai World's Fair and the Guangzhou Asian Games in 2010, the development at home of film material has entered a rapid growth period.Membrane material is the key of building membrane structure, and China's investigation and application is started late, and technical merit is lower, and most of membrane material also mainly relies on import.
Interior trim film internal and overseas also has larger gap, and the ability of domestic topical product or technology may possess, but is possessing in modular system Integrated Development ability and there is a big difference.Current this respect market all monopolize by some transnational suppliers.Domestic many car load factories, when developing new model, can invite these transnational Supplier involvement Synchronization Design exploitations, even by the integration being responsible for whole interior trim project, contribute to ensureing product quality and development management.
PVDF thin film is then the fastest kind of growing up in fluoro-containing copolymer film, and American market average growth rate per annum reaches 7.6%.At present, by PVDF thin film and PP Film laminated.In addition, PVDF thin film and other films have good compatibility, and the popularization of plural layers is while its performance of maintenance, more economical.The development in PVDF thin film market mainly has benefited from the generally use of lithium battery.At present, the fast development of mobile phone, notebook computer, portable type electronic product, solar panel, building and automobile decoration film and semicon industry has promoted widely using of this kind of film.In addition, pvdf membrane is also just more and more for fields such as fuel cell, aircraft inside gadget and business automation equipments.PVDF and PVC composite membrane just has the market demand widely as a kind of building decoration film, and along with technological innovation in the market share of the outdoor films such as the fenestrated membrane of the developed countries such as America and Europe in occupation of more than 90%.
Ultraviolet irradiation (UV) absorbent is added in one deck of polymer film by existing weatherable films.But the ultraviolet radiation absorber of high concentration causes the mechanical performance of this polymer film to decline usually, and cause in polymer film muddy.In addition, previous author also finds, UV absorbent causes the performance of film to decline along with the time from the release polymer film.As a result, the service life of polymer film is restricted, and the substrate that it covers or assembly may be damaged along with the degraded of diaphragm.Therefore, a kind of weather resistant polymer film of improvement is needed.
Summary of the invention
For solving the problem, PP base material decorating film disclosed by the invention, have weatherability strong, ageing resistace is good, and mechanical performance is superior, not easily occurs damaged or peels off, and having the building decoration film of good wearability.
PP base material decorating film disclosed by the invention, comprise the filmated base material of fluorine-containing Modified Membrane and PP material, fluorine-containing Modified Membrane and base material layered are fitted, fluorine-containing Modified Membrane comprises surface layer, and (constitutive material of surface layer comprises the base material of 100 weight portions and the PTFE micro mist of 0-10 weight portion, PTFE micro mist is adopted not only to have good compatibility with matrix, PTFE micro mist can also strengthen surface layer simultaneously, thus improve the wearability of surface layer, strengthen weatherability), barrier layer and tack coat, tack coat, barrier layer and surface layer fit on base material by the outside sequentially layered of base material, surface layer material is fluorine-containing polymer, tack coat is the one in the Blend rubber adhesive layer of PVC adhesive layer and PVDF and Resin A, Resin A be one in the random copolymer of modified PMMA or nano modification copolyamide and ethene or both.
The one of PP base material decorating film disclosed by the invention is improved, and tack coat, barrier layer and surface layer are fitted on base material by the outside sequentially layered of base material in base material both sides.
The one of PP base material decorating film disclosed by the invention is improved, mainly consisting of (with weight parts) of barrier layer, PVDF40 ~ 100 part, ultraviolet absorber 0.1 ~ 1 part, flexibilizer 5 ~ 15 parts, antioxidant 0-1 part, cold-resistant agent 0-1 part.The auxiliary agent outer application all representing common auxiliary agent unless specified otherwise such as flexibilizer, antioxidant and weather resisting agent.
The one of PP base material decorating film disclosed by the invention is improved, modified PMMA 0 ~ 60 part that barrier layer also comprises (with weight parts).
The one of PP base material decorating film disclosed by the invention is improved, one or both in fluorine-containing polymer PVDF, PTFE, PFA, PCTFE.Surface layer is preferably, and the raw material of surface layer consists of the PTFE micro mist of the base material of 100 weight portions (base material be in fluorine-containing polymer PVDF, PTFE, PFA, PCTFE one or both) and 0-10 weight portion.Adopt PTFE micro mist to be conducive to improving surface abrasion resistance and the self-cleaning performance of surface layer, while continuity decorating film service life, make its more easy care.
The one of PP base material decorating film disclosed by the invention is improved, mainly consisting of (with weight parts) of tack coat, the random copolymer 80 ~ 100 parts of nano modification copolyamide and ethene, PVDF0 ~ 20 part.Wherein the random copolymer of nano modification copolyamide and ethene is the random copolymer with the copolyamide of nano material (comprising nanofiber or nanoparticle etc.) modification and ethene.
The one of PP base material decorating film disclosed by the invention is improved, mainly consisting of (with weight parts) of tack coat, modified PMMA 80 ~ 100 parts, PVDF0 ~ 20 part.In the present invention modified PMMA refer to PMMA material for the requirement of decorating film different and improving routinely in printing opacity, intensity, fire-retardant, anti-aging and polishing machine etc. of making.
PP base material decorating film disclosed by the invention, surface layer adopts fluorinated polymer material to have lower surface tension, thus has antifouling self-cleaning property, and rainwater can wash away the attachment on film surface; Barrier layer can intercept ultraviolet and steam etc., thus plays the effect of protection base material; Tack coat makes base material and diaphragm can be good at laminating, and long-time use is not vulnerable to the osmosis of pollution, does not come off, does not wrinkle.
Resistance to soiling: spot easy cleaning is removed to the difficulty such as oil smoke, oiliness pen and ink, and not by time restriction, pollute for a long time and still easily cleaned, can not adhere on decorating film;
