Abstract

A paper base plastic film whiteboard for painting and writing uses paper as a base board, a layer of glue is coated on the base board, a layer of plastic membrane is compounded on the glue, and the glue can also be bound on a hard thin plate to be made into various whiteboards to use. Coloured art pens, pens, ball-pens, etc. can be used to write and paint on the utility model, the writing and painting effect is the same as on white paper, and the writing and painting marks can be cleaned by wet dishcloth. The board surface can keep the primary color for long time. The utility model is cheap in price and light in weight, and the board surface can be changed. The utility model can replace blackboards and steel whiteboards.

Description

Paper base with plastic film board for painting and writing

The utility model relates to a kind of and blackboard, cultural goods that other types blank purposes is identical.

Painting and calligraphy blank in the market is to be coated with white paint to make on sheet metal.Painting and calligraphy, particularly time are difficult for wiping clean than after long in the above, and if things go on like this, white plate face becomes dirty and can not use.This blank costs an arm and a leg, and weight is heavier.

The purpose of this utility model is that a kind of novel painting and calligraphy blank will be provided.It can overcome the various shortcomings of steel blank effectively, and has the unexistent new purposes of general blank.

The purpose of this utility model is achieved in that with paper to be substrate, is coated with one deck glue thereon, compound layer of plastic film on glue.Certainly, also can it can two-sidedly be used in the also compound layer of plastic film of the another side of paper substrate plate in order to improve service efficiency.Requirement to paper is: certain thickness and deflection be arranged, be suitable for the multiple film of mechanical gluing.If plastic sheeting is water white, the color of paper should be white or other very shallow colors.To plastic sheeting, required thickness is thinner, and tensile strength is good, and face is harder relatively, also should be suitable for the multiple film of mechanical gluing.Generally should use the plastic sheeting of biaxial tension, as the polyester film of biaxial tension, polypropylene film etc.It is water white that plastic sheeting generally should be, but also can use very light colour of white or other.As not using water white plastic sheeting, then the color to the paper substrate plate does not require.

When using the colourless transparent plastic film to make, can be according to different instructions for uses, printing is various on paper substrate writes with line, lattice, (as lined, manuscript paper lattice, grid, double check with a core, english writing lattice, staff lattice etc.) print various test patterns, numeral, letter, literal, hard-tipped pen calligraphical works copybooks etc. also can print various chessboards and specific form etc.The effect that stamps these lines, lattice, figure, literal etc. is to make the utility model use face wider.

The utility model can have multiple embodiments, both can directly use, and also can make various hard blanks again and use.For example it can be attached on the hard sheet, (hard sheet can be various wood based panels, hardboard, magnesite composite board, glass epoxy, plastic plate, metallic plate etc.) limit portion is pressed on blank on the hard sheet with moulding and securing member.The advantage of this hard blank is that the plate face can be convenient for changing.A hard blank, the attached blank in the two sides of hard sheet has four use faces, and can change the blank of more different printing literal and pattern.

The structure of another kind of hard blank is that blank (only needing a composite plastic film) gluing is compounded on the hard sheet.This structure is often used for making the bigger hard blank of area.In order to make the blank can be adsorbed by magnetisable material as the steel blank, the steel plate that also can compound one deck is very thin between blank and hard sheet or the metal film of steel.It has just had whole advantages of steel blank like this.The utility model is compared with existing various blanks has following advantage:

1, can on blank, write picture with coloured art pen, pen, ball pen etc.Its painting and calligraphy effect is with the same on blank sheet of paper, with wet rag once wiping, even and the time longly also can wipe totallyer, (wiping unclean unlike the steel blank) makes the plate face can keep primary colors for a long time.(also can write picture, but will wipe) with rubber with black pencil

2, production cost is very low, two-sided use, and as being used on the hard blank, can change, make its service life very long.

3, in light weight, easy to carry and use.

4, generally write with the purposes of blank except having, multiple use can also be arranged.As making the practice board that uses for the pupil who has just gone to school, can make the hard-tipped pen calligraphical works copybook that can write wiping repeatedly of study hard-tipped pen calligraphical works, can make various chessboards, drawing exercise, interim account, uses such as mathematical operation rough draft.It not only can replace expensive steel blank, and can replace blackboard fully.(replacing blackboard with blank, beneficial) to the protection student eyesight

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Embodiment 1:

Fig. 1 is the generalized section of the utility model embodiment 1.

(1) for thickness being 0.2 millimeter blank sheet of paper, is substrate with paper, uses dry compound machine or coating machine gluing (2) thereon, and water white thickness is 0.05 millimeter polyester film (3) compound on the glue again.Another side at paper also carries out same multiple film.Then the utility model being cut into required size uses.

Embodiment 2:

Fig. 2 is the generalized section of the utility model embodiment 2.

(4) be the utility model embodiment 1, two (4) are attached to the two sides of three-ply board (5), use moulding (6) and (7) and securing member (8) to compress all around.

Embodiment 3:

Fig. 3 is the generalized section of the utility model embodiment 3.

(9) be the multiple plastic sheeting blank of paper substrate single face of the present utility model.Go up gluing (11) at three-ply board (10), outside (9) plastic sheeting is faced, be compounded on the glue face of three-ply board.

Claims

1, a kind of painting and calligraphy blank is characterized in that with paper being substrate, scribbles one deck glue thereon, compound layer of plastic film on glue.

2, blank according to claim 1 is characterized in that on the paper substrate plate it can being the single spreading composite plastic film, also can be all gluing composite plastic films of two sides.

3, blank according to claim 1 and 2 is characterized in that blank can be attached on the hard sheet, and limit portion compresses blank with moulding and securing member.

4, blank according to claim 1 and 2 is characterized in that blank can be compounded on the hard sheet by gluing.
