CN201607603U - Projection screen - Google Patents

Abstract

The utility model relates to a projection screen, which is in a film sheeting structure. The film sheeting structure comprises a printing layer, a no-glue suction sticking layer with adsorptive power and a protective layer from top to bottom in sequence, wherein the protective layer can let the surface to keep flat, and all the layers are closely jointed together. The projection screen has the advantages that the adsorptive effect is good; as the projection screen is provided with the no-glue suction sticking layer, the projection screen does need nailing and hanging in use, and the damage of posted objects and the pollution of posted cardinal planes are avoided when the posted objects are removed; the surface of the product can be written or drawn, and written letters and drawn patterns can be erased; and the projection screen can be used for repeatedly posting and can be repeatedly used.

Description

Projection screen

Technical field

The utility model relates to a kind of projection screen that repeats to be attached on any plane.

Background technology

The present projection screen that uses, the shortcoming of existence is: volume is bigger, thick and heavy, and it is big to take up room, and be difficult to carrying and collection, need during use that its nail is hung over wall or plate etc. and hang up on the basal plane, and it can't change arbitrarily in use and hang up the position, bring many inconvenience to the user.

The utility model content

The purpose of this utility model is to solve the problems of the prior art, and a kind of projection screen that can arbitrarily repeat to be attached on any plane is provided.

The technical solution of the utility model is: a kind of projection screen; it is the film schistose texture, and this film schistose texture comprises printed layers from top to bottom successively, and the no glue with absorption affinity is inhaled paste layer; with can make its surface keep open and flat protective seam, each layer fits tightly together.

The thickness of described printed layers is 10～15 μ m.

The thickness that described no glue is inhaled paste layer is 15～20 μ m.

The thickness of described protective seam is 10～50 μ m.

The beneficial effects of the utility model are: 1, advantages of good adsorption effect, because having no glue suction, it pastes material layer, and it need not nail in use and hangs, and has avoided when extracing sticker, causes the damage of sticker and the pollution that quilt pastes basal plane; 2, the utility model product surface can be write or draw, and the literal of writing and draw a design and can wipe; 3, can repeatedly put up, reuse.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of projection screen of the utility model, it is the film schistose texture, this film schistose texture comprises printed layers 1, no glue suction paste layer 2 and protective seam 3 from top to bottom successively.

Wherein printed layers 1 is made by 10～15 μ mPP materials or PE material, through corona treatment, has drop shadow effect, is fit to simultaneously write, and the user can write on projection screen or draw, and the literal of writing and draw a design and can be wiped free of, and reuses; No glue is inhaled paste layer 2 and is made 15～20 μ m films by the filling material that polyene hydrogen resin adds part generation and storage absorption affinity, loads through high-pressure electrostatic again, makes this material have unique no glue Electrostatic Absorption ability; Protective seam 3 is made by 15～50 μ mPP materials, makes product keep calming down with well-pressed.Filling agent is one or more in lime carbonate, titania, talcum, chalk, the pigment described in the no glue suction paste layer material, and the mode by high-pressure electrostatic loads makes material have adsorptive power.

The surface that the utility model can be attached at any plane or omit the tool radian when using, such as: other appropriate locations such as wall, glass plate, while is in light weight and thin because of film, except that being cut into the required shape arbitrarily, and employing reel packaged, the mode of cutting dotted line with cutter is easily torn and random one is puted up, and reaches to save the space and be convenient to the effect of transporting and conveniently exchangining cards containing all personal details and become sworn brothers and collecting; The utility model projection screen is inhaled to be attached to and is pasted on the basal plane in addition, need not to implement nail and hangs, and can avoid when extracing sticker the pollution that causes the damage of sticker and pasted basal plane.

Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
