Abstract
The invention belongs to the film technology of resin, relating to improvement of a method for forming a resin film by transfer printing. The adopted transfer printing device comprises a feeding roller (1), a glue spreader (2) and a glue squeezing roller (3). The forming of the resin film comprises the following steps: coating, wherein the glue spreader (2) rotates clockwise, the glue squeezing roller (3) rotates anticlockwise, and the rotating speed v3 of the glue squeezing roller (3) is 1.5-20 folds of rotating speed of the glue spreader (2), and transfer printing, wherein the rotating speed v1 of the feeding roller (1) is 1.5-5 folds of rotating speed of the glue spreader (2).

Description
Technical field
The invention belongs to the resin film technique, relate to the improvement that transfer printing is formed the resin molding method.
Background technology
At present; The principle that adopts transfer printing formation resin molding method is referring to Fig. 1; The transfer apparatus that is adopted comprises feeding-in roll 1, glue spreader 2 and plastic squeeze roller 3; Between the left side on the face of cylinder on the right side on the face of cylinder on the glue spreader 2 and the plastic squeeze roller 3, form glue groove 4, barrier paper 5 passes the gap between feeding-in roll 1 and glue spreader 2, and the resin molding on the glue spreader 2 is transferred on the transfer paper 5.The direction of rotation of glue spreader 2 and plastic squeeze roller 3, glue spreader 2 turns clockwise, and plastic squeeze roller 3 is rotated counterclockwise.Feeding-in roll 1, glue spreader 2 are identical with the rotating speed of plastic squeeze roller 3.The shortcoming of above-mentioned transfer printing resin film forming is:
(1) thickness of resin film is determined by glue groove gap.Feeding-in roll 1, glue spreader 2 are identical with the rotating speed of plastic squeeze roller 3, and resin forms resin molding from the surface that glue groove 4 is coated to glue spreader 2, and thickness of resin film is by the gap decision of glue spreader 2 and plastic squeeze roller 3, and thickness of resin film is constant in process of production.Therefore; Require the gap of glue groove 4 narrow when producing the resin molding of low surface density; When the resin system of multi-phase ingredients passed through glue groove gap, different resin Compositions was different through the speed in above-mentioned gap, made the resin on the glue spreader produce the branch phase behavior; And then make the skewness of the multi-phase ingredients in the resin molding, cause resin molding defective;
(2) direction of rotation of glue spreader 2 and plastic squeeze roller 3; Make resin flows direction in the glue groove only towards the direction in gap; And the backflow that can not produce resin in the glue groove is unfavorable for making the mixing of resin in the glue groove through the slow resin Composition of glue groove gap speed and will assemble at the glue trench bottom; Also can make the skewness of the multi-phase ingredients in the resin molding, cause resin molding defective.
Summary of the invention
The objective of the invention is: propose a kind of method that can make the equally distributed transfer printing formation of the multi-phase ingredients resin molding of resin in the glue groove; To overcome the problem that multi-phase ingredients is assembled at the glue trench bottom through the speed difference and the slow resin Composition of speed in gap, guarantee the quality of resin molding.
Technical scheme of the present invention is: adopt transfer printing to form the method for resin molding; The transfer apparatus that is adopted comprises feeding-in roll 1, glue spreader 2 and plastic squeeze roller 3; Between the left side on the face of cylinder on the right side on the face of cylinder on the glue spreader 2 and the plastic squeeze roller 3, form glue groove 4; Barrier paper 5 passes the gap between feeding-in roll 1 and glue spreader 2, and the resin molding on the glue spreader 2 is transferred on the transfer paper 5; It is characterized in that the step that forms resin molding is following:
1, film: in being coated with membrane process, glue spreader 2 clockwise rotates, and plastic squeeze roller 3 rotates counterclockwise, the slewing rate v of glue spreader 2
2=5rpm～30rpm, the slewing rate v of plastic squeeze roller 3
3Be 1.5～20 times of glue spreader 2 slewing rates, the resin that is in molten condition forms resin molding from the surface that glue groove 4 is coated to glue spreader 2;
2, transfer printing: glue spreader 2 lip-deep resin moldings are transferred on the barrier paper 5 the slewing rate v of feeding-in roll 1 through the rotation of glue spreader 2 and feeding-in roll 1
1Be 1.5～5 times of glue spreader 2 slewing rates.
Advantage of the present invention is: proposed a kind of method that can make the equally distributed transfer printing formation of the multi-phase ingredients resin molding of resin in the glue groove; Overcome the problem that multi-phase ingredients is assembled at the glue trench bottom through the speed difference and the slow resin Composition of speed in gap, guaranteed the quality of resin molding.Evidence, existing transfer printing forms the resin molding that the resin molding method can not be produced the multi-phase ingredients of low surface density; And after employing the inventive method, the qualification rate of producing the resin molding of the multi-phase ingredients that hangs down surface density continuously is more than 99%.
Description of drawings
Fig. 1 adopts transfer printing to form the principle schematic of resin molding method at present.
Fig. 2 is a principle schematic of the present invention.
The specific embodiment
Explain further details in the face of the present invention down.Referring to Fig. 2; Adopt transfer printing to form the method for resin molding; The transfer apparatus that is adopted comprises feeding-in roll 1, glue spreader 2 and plastic squeeze roller 3; Between the left side on the face of cylinder on the right side on the face of cylinder on the glue spreader 2 and the plastic squeeze roller 3, form glue groove 4, barrier paper 5 passes the gap between feeding-in roll 1 and glue spreader 2, and the resin molding on the glue spreader 2 is transferred on the transfer paper 5; It is characterized in that the step that forms resin molding is following:
1, film: in being coated with membrane process, glue spreader 2 clockwise rotates, and plastic squeeze roller 3 rotates counterclockwise, the slewing rate v of glue spreader 2
2=5rpm～50rpm, the slewing rate v of plastic squeeze roller 3
3Be 1.5～20 times of glue spreader 2 slewing rates, the resin that is in molten condition forms resin molding from the surface that glue groove 4 is coated to glue spreader 2;
2, transfer printing: glue spreader 2 lip-deep resin moldings are transferred on the barrier paper 5 the slewing rate v of feeding-in roll 1 through the rotation of glue spreader 2 and feeding-in roll 1
1Be 1.5～5 times of glue spreader 2 slewing rates.
Operation principle of the present invention is:
1, the slewing rate v of the clearance delta h between film thickness δ and glue spreader 2 and the plastic squeeze roller 3, feeding-in roll 1
1, glue spreader 2 velocity of rotation v
2, plastic squeeze roller 3 velocity of rotation v
3Between theoretical formula be:
In the technical scheme of the present invention, the slewing rate v of plastic squeeze roller 3
3Be 1.5～20 times of glue spreader 2 slewing rates, the slewing rate v of feeding-in roll 1
