Description
Technical Field
The utility model belongs to the technical field of the film, concretely relates to mute smooth face high tenacity polycarbonate film.
Background
The polycarbonate film or the PC film is a film prepared by taking polycarbonate resin as a base material, has stable size, ultraviolet light resistance, excellent toughness, high strength, difficult tearing and damage, easy adhesion, easy printing and good formability, is used for screen printing of various labels, is suitable for various processing modes such as plastic sucking, laminating and the like, has excellent electrical property, high resistance and low dielectric loss, simultaneously has excellent flame retardance, is an excellent insulating material, and is extremely suitable for insulating shielding of electric appliances, shells of power batteries and the like.
The toughness of the existing polycarbonate film is reduced due to various factors such as processing parameters, and the like, so that the existing polycarbonate film has the defects of easy tearing or uneven thickness and the like when being actually applied to products, the quality of finished products is seriously influenced, resources are easily wasted, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned limitation, provide a toughness intensity is high, still keeps mute plain noodles and can not appear the high toughness polycarbonate film of mute plain noodles of uneven defect of thickness after the tensile.
The purpose of the utility model is realized through the following technical scheme: the utility model provides a high tenacity polycarbonate film of matte face, including first substrate layer, the second substrate layer, third substrate layer and fourth substrate layer, second substrate layer and third substrate layer are located between first substrate layer and the fourth substrate layer, the second substrate layer is the structure that a plurality of horizontal strips and transparent film are constituteed, the third substrate layer is the structure that a plurality of vertical strips and dull polish film are constituteed, first substrate layer, the second substrate layer, all closely laminate between third substrate layer and the fourth substrate layer each layer, first substrate layer surface is handled through the matte, fourth substrate layer bottom surface is equipped with the glue film.
Preferably, the structure formed by the plurality of transverse strips of the second substrate layer and the transparent film is a structure formed by connecting the transparent film between two adjacent transverse strips.
Preferably, the structure formed by the plurality of longitudinal strips of the third substrate layer and the frosted film is a structure formed by connecting the frosted film between two adjacent longitudinal strips.
Preferably, the plurality of transverse strips of the first substrate layer, the plurality of transverse strips of the second substrate layer, the plurality of longitudinal strips of the third substrate layer and the fourth substrate layer are made of polycarbonate resin.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides a high tenacity polycarbonate film of matte face, including first substrate layer 1, second substrate layer 2, third substrate layer 3 and fourth substrate layer 4, second substrate layer 2 and third substrate layer 3 are located between first substrate layer 1 and fourth substrate layer 4, second substrate layer 2 is the structure that a plurality of horizontal strips and transparent film are constituteed, third substrate layer 3 is the structure that a plurality of vertical strips and dull polish film are constituteed, first substrate layer 1, second substrate layer 2, all closely laminate between third substrate layer 3 and the fourth substrate layer 4 each layer, 1 surface of first substrate layer is handled through the matte, 4 bottom surfaces of fourth substrate layer are equipped with glue film 5. The structure formed by the plurality of transverse strips of the second substrate layer 2 and the transparent film is specifically a structure formed by connecting the transparent film between two adjacent transverse strips. The structure formed by the plurality of longitudinal strips of the third substrate layer 3 and the frosted film is specifically a structure formed by connecting the frosted film between two adjacent longitudinal strips. No matter the structure that a plurality of horizontal strips and transparent film of second substrate layer 2 constitute is under horizontal or vertical tensile stress, the uneven condition of thickness can not appear, and under the long time vertical tensile stress's condition of time, the dull and stereotyped nature of whole film can be guaranteed to the dull and stereotyped nature of dull polish film in practical application to the structure that a plurality of vertical strips and dull polish film of third substrate layer 3 constitute, and the offsetting of vertical stress also can avoid the uneven condition of thickness to appear simultaneously. The transverse strips and the transparent film and the longitudinal strips and the frosted film are tightly connected through adhesive tapes.
The first substrate layer 1, the plurality of transverse strips of the second substrate layer 2, the plurality of longitudinal strips of the third substrate layer 3 and the fourth substrate layer 4 are all made of polycarbonate resin.
The surface of the first substrate layer 1 is provided with a matte material, the matte material can be attached to the surface of the first substrate layer 1 and covered with a transparent film layer, and the adhesive layer 5 is thermosetting resin adhesive and can be conveniently covered on the surface of a product.
