Abstract
The invention discloses a preparation forming technology of a PET (Polyethylene Terephthalate) hairline crack film. The preparation forming technology comprises the steps as follows: in step one, a layer of solvent-free UV (Ultra Violet) gel is coated on the front side of the PET film; in step two, the PET film that is coated with the solvent-free UV (Ultra Violet) gel passes through acting force points of a hairline crack die roller and a rubber roller, the hairline crack die roller can squeeze a solvent-free UV gel layer on the front side of the PET film, and the solvent-free UV gel layer is processed through UV solidification treatment at the same time when being squeezed; concave-convex textures are formed on the hairline crack die roller, so that the textures formed on the hairline crack die roller are pressed on the solvent-free UV gel layer; demoulding is carried out when the solvent-free UV gel layer satisfies the demoulding hardness requirement; and the solvent-free UV gel layer is processed through UV solidification continuously after demoulding, and the PET hairline crack film is formed finally. The preparation forming technology can solve the problem that scraps which are generated when hairline cracks are carved on the surface of the PET film through friction in a traditional production mode are difficult to clean out.
Description
Technical field
The present invention relates to a kind of preparation moulding process of PET hairline film.
Background technology
Traditional processing technology is: utilize mechanical system in PET film mantle friction weaving done in fine silks and gold thread by the tapestry method, thereby form the PET drawing film.Yet, this traditional mode of production mode, the shape of texture is difficult to control on the PET drawing film, and when PET film mantle friction weaving done in fine silks and gold thread by the tapestry method, the film that the pet sheet face can occur is considered the problem that is difficult to clean out to be worth doing, influences the quality of product.
Summary of the invention
The present invention seeks to: to the problems referred to above, a kind of preparation moulding process of PET hairline film is provided, the present invention can solve the problem that chip that the traditional mode of production mode produces is difficult to clean out when PET film mantle friction weaving done in fine silks and gold thread by the tapestry method.The PET hairline film that this technology makes has uneven stereoeffect, can be used as high emulation stainless steel membrane and uses in household electrical appliances manufacturing field.
Technical scheme of the present invention is: a kind of preparation moulding process of PET hairline film is characterized in that this technology may further comprise the steps:
Step 1, in the front of PET film the solvent-free UV glue of coating one deck;
Step 2, will be coated with PET film behind the solvent-free UV glue through the force position of hairline mold roller and rubber roll; Said hairline mold roller is pushed the positive solvent-free UV glue-line of PET film; In the time of extruding solvent-free UV glue-line is carried out the UV cured; Be shaped on uneven texture on the hairline mold roller, thereby the texture on the hairline mold roller is pressed on the solvent-free UV glue-line, treat that solvent-free UV glue-line carries out the demoulding when reaching demoulding hardness requirement; Demoulding continued is carried out the UV cured to solvent-free UV glue-line, finally forms PET hairline film.
As preferably, in the said step 1, the thickness of said PET film is 20 ~ 100um, and width is 800 ~ 1500mm, and surface tension is more than 54dyn.
As preferably, in the said step 1, the viscosity of said solvent-free UV glue is 500 ~ 1500mPa.s.
As preferably, in the said step 1, be 3 ~ 20um at the bondline thickness of the solvent-free UV glue of this one deck of the front of PET film coating.
As preferably, in the said step 2, said hairline mold roller is a metal material, is provided with hydrologic cycle cooling system in it.
As preferably, in the said step 2, the pressure of the force position of said hairline mold roller and rubber roll is 9.8 ~ 39.2N.
Advantage of the present invention is: the present invention has adopted and the diverse production technology of conventional art; The mode in friction weaving done in fine silks and gold thread by the tapestry method on the PET basement membrane in the traditional processing technology is changed into: on the PET basement membrane, be coated with solvent-free UV glue-line earlier; Utilize the hairline mold roller that solvent-free UV glue-line is pushed again; Thereby the texture on the hairline mold roller is pressed in (the uneven texture of formation on solvent-free UV glue-line) on the solvent-free UV glue-line; The final PET hairline film that forms, this PET hairline film has uneven stereoeffect, can be used as high emulation stainless steel membrane and uses in household electrical appliances manufacturing field.And; The present invention can be through making the hairline mold roller of different decorative patterns (texture); Make the product of do not suit type and texture; Technological operation is convenient, and the control of shaping pattern uniformity is easy, precision is high, has overcome texture control difficulty, chip cleaning difficulty and the single shortcoming of decorative pattern in the technology of mechanical friction weaving done in fine silks and gold thread by the tapestry method in the past.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a process chart of the present invention.
The specific embodiment
With reference to shown in Figure 1, the preparation moulding process of the PET hairline film of present embodiment may further comprise the steps:
Step 1, (be solvent-free ultraviolet curing glue at the solvent-free UV glue of the positive coating of the PET of thick 20 ~ 100um, wide 800 ~ 1500mm film (the former film of PET) one bed thickness 3 ~ 20um; Its viscosity is preferably between 500 ~ 1500mPa.s), thereby at the solvent-free UV glue-line of the positive formation of PET film.The surface tension of said PET film is preferably in more than the 54dyn.
Step 2, will be coated with PET film behind the solvent-free UV glue, said hairline mold roller is pushed the positive solvent-free UV glue-line of PET film, in the time of extruding solvent-free UV glue-line carried out the UV cured through the force position of hairline mold roller and rubber roll.Be shaped on uneven texture on the hairline mold roller; Thereby the texture on the hairline mold roller is pressed in (the careful hair texture of formation on solvent-free UV glue-line) on the solvent-free UV glue-line; Treat that solvent-free UV glue-line carries out the demoulding (that is: the PET film being separated from the hairline mold roller) when reaching demoulding hardness requirement; Demoulding continued is carried out the UV cured to solvent-free UV glue-line; Make solvent-free UV glue-line reach the hardness of product requirement, finally obtain PET hairline film, the hair texture on the PET hairline film that obtains is very approaching with the hair texture of real stainless steel wire drawing plate.
Said hairline mold roller is a metal material, is provided with hydrologic cycle cooling system in it, and water temperature is controlled at below 25 ℃.The pressure of the force position of hairline mold roller and rubber roll is 9.8 ~ 39.2N.
The applicant adopts above-mentioned process, utilizes thickness to go out three PET hairline films for the former film preparation of the PET of 30um, 31um and 32um respectively, and the performance test results of these three PET hairline films sees the following form:
