Abstract

The present invention relates to a PVC for an image projector, and has a cylindrical shape having a circumferential angle within 120 to 150 ° so as to be uniformly and widely reflected on the surface, and formed adjacent to a vertical line having an arc diameter of 50 to 300 μm, and aluminum on the surface. The present invention relates to a projector tarpaulin screen capable of forming a print layer and a coating layer to express a clear image, and a method of manufacturing the same.

Description

Tarpaulin for screens with aluminum light diffusion embossing and manufacturing method {Tarpaulin for projector screen with a reflection embossing and manufacturing method}

1 is a cross-sectional view of the tarpaulin screen of the present invention

Figure 2 is a perspective view and a cross-sectional enlarged view of the reflective embossed sheet of the present invention

3 is a light reflection pattern diagram of a reflective embossed sheet of the present invention

Figure 4 is a cross-sectional view of the screen for tarpaulin omitting the PVC sheet of the present invention

The technical field to which the present invention pertains relates to tarpaulins used for projector screens, and in the case of conventional screens, fine embossing is formed on the surface of a fabric, fine glass grains are applied, or light diffusing agents are applied to express clear images by increasing reflectance. It was. However, in the case of glass balls, only the bright spot is projected by the reflex reflection of the hemispherical shape. In addition, if the surface of the tarpaulin white matte or indoors with the ambient light source, the image can be displayed only by using a high-light projector, there is a problem that can not display a clear color under the influence of the ambient light source.

The technical problem to be achieved by the present invention is to form a fine vertical streak embossing, a high reflectivity aluminum printing layer, a light diffusing coating layer on the surface of the PVC tarpaulin for the screen, a projector screen capable of expressing a clear image even in the environment with high light reflection It is to provide a tarpaulin and a method for producing the same.

The composition of the present invention is composed of a tarpaulin for the screen composed of a light diffusion coating layer, an aluminum printing layer, a primer printing layer, a PVC embossed sheet, an adhesive, a PVC sheet, an adhesive, a fiberglass fabric, an adhesive, a PVC blackout sheet, and a manufacturing method thereof. do.

In Figure 1, the screen tarpaulin of the present invention is a base tarpaulin (15) having a glass fiber fabric that is flexible enough to roll and roll on a roll to prevent wrinkles and left and right deformation and high light reflection and left and right scattering on the screen surface, It can be divided into PVC reflective embossing sheet 14 which expresses a clear image by refraction.

In the case of the base tarpaulin 15, a plasticizer and a pigment are added to the PVC by a calendering method in the same manner as a general screen tarpaulin, and a white pigment is applied to the front PVC sheet 11b, and a black pigment is applied to the rear PVC black film sheet 11c. After the addition, the glass fiber fabric 13 and the adhesives 12b and 12c are bonded together.

PVC sheet thickness of the front and back of the base tarpaulin (15) is 0.05 ~ 0.5mm, about 28 to 45 parts by weight of plasticizer (DOP) is processed into a calendar with a heat stabilizer, and the fiberglass fabric 13 to the front and back adhesive ( 12b and 12c) to process the base tarpaulin (15).

In FIG. 2, the embossing of the PVC embossed sheet 24 of the present invention forms an aluminum printing layer 22 and a light diffusion coating layer 21 on the surface thereof so that the circumferential angle 26 can be widely and uniformly reflected from side to side. 120 to 150 degrees within the shape of the bow, the arc arc diameter (25) of 50 ~ 300㎛ within a shape in which the fine vertical string of the embossed (20) arranged adjacently,

In FIG. 3, the light source 31 projected from the front surface is reflected 32 evenly from the center to the neighboring emboss 33 by minimizing re-reflection interference. The primer printing layer 23, the aluminum printing layer 22, and the light diffusing coating layer 21 of a thin film of 0.1 mm or less are embossed together with the PVC emboss sheet 24 to form a three-dimensional shape of the embossing light source projected by the projector from the surface. As a result, the left and right sides are equally reflected, and a clear image is displayed by refraction and light diffusion.

The primer printing layer 23 serves as a printing pretreatment process to stably print aluminum particles having very small particles on the PVC emboss sheet 24. In the case of aluminum metal paints having very small particles, the gravure printing method is used. Two or more repeated printings can produce a uniform aluminum printing layer 22 on the PVC surface.

The light diffusion coating layer 21 is formed by thinly gravure printing the aluminum printing layer by protecting the aluminum printing layer 22 by uniformly adding a very small and light-diffusing metal compound or glass, ore to the transparent coating resin. At the same time, it displays sharp images through refraction and light diffusion on the surface.

In the method for producing a tarpaulin for screen of the present invention,

Add plasticizer, pigment, and heat stabilizer to PVC to process black and white PVC sheets by calendering method, respectively, and attach one white and black PVC sheet to adhesive on front and back of fiberglass fabric, and then to base tarpaulin (15). and,

After printing a separate PVC sheet by primer printing, the surface of the aluminum coating is printed with a gravure method on the surface of the aluminum particle which is very small. It becomes dry.

The printed coated PVC sheet is processed into a PVC reflective embossed sheet 14 in which an emboss having a vertical vertical line shape is formed by applying heat and pressure to the vertically-lined embossed 20 roll of the present invention, and the base tarpaulin 15 and the PVC reflective embossed sheet. It is completed by adhering the 14 to the adhesive 12a.

In another manufacturing method, the PVC tarpaulin 11b on the front of the fiberglass fabric is omitted from the base tarpaulin, and the PVC reflective embossing sheet 45 is coated with the adhesive 42a on the fiberglass 43 before the embossing process. Embossing with heat and pressure in the vertical roll bow embossed 20 shape of the present invention is completed by bonding at the same time.

When omitting the front PVC sheet 11b of the base tarpaulin and adhering the PVC emboss sheet 41 at the same time as embossing, the structure of the glass fiber fabric 43 so that the glass fiber fabric shape is not engraved on the surface of the PVC emboss sheet 41. This sufficiently dense and embossed PVC sheet should be thick enough.

In the embossing process, the light diffusion coating layer 10a, the aluminum printing layer 10b, and the primer printing layer 10c together with the PVC emboss sheet 11a become the vertical vertical emboss of the present invention, and the light diffusion coating layer 10a is The aluminum print layer 10b is protected from being destroyed in the embossing process and at the same time serves to refract and diffuse light.

When the high efficiency reflective material such as aluminum is applied to the screen tarpaulin, the effects of the present invention cannot be used as a narrow viewing angle problem that is very bright at the center of the screen and darkens toward the edge with high reflectance and glare due to direct reflection. Can be used to produce screen tarpaulins that can watch clear images at high brightness without using blackout curtains in brightly lit rooms or bright daylights, and can be conveniently rolled up to reduce the cost of manufacturing high-brightness screens. You can do it.
