Description
Technical Field
The invention relates to the technical field of dry film production, in particular to a dry film production process.
Background
Dry film is a relatively wet film in coating, and dry film is a high molecular compound which can generate a polymerization reaction (a reaction process of synthesizing a polymer from a monomer) after being irradiated by ultraviolet rays to form a stable substance to be attached to a plate surface, thereby achieving the function of blocking electroplating and etching.
During current dry film production, generally adopt the three-layer design to going on producing, but current dry film production is generally comparatively stricter to environmental control for the mobility of dry film when producing is relatively poor, thereby makes dry film production thickness and quality have certain deviation, can not be fine carry out subsequent work.
Disclosure of Invention
The dry film production process provided by the invention solves the problem of deviation in production.
In order to achieve the purpose, the invention adopts the following technical scheme:
a dry film production process comprises the following steps:
s1; adding an adhesive, a photopolymerization monomer, a photoinitiator, a plasticizer, a thickening agent, a thermal polymerization agent, a pigment and a solvent into a mixing reaction kettle, heating to 110-170 ℃, stirring and mixing until all raw materials are uniformly mixed, and simultaneously fixing a polyester film and a polyethylene film on one side of the device;
s2; under the closed dark environment, the extruder and the winder are synchronously started, the polyester film and the polyethylene film of the winder are wound, the raw materials mixed in the step S1 are directly extruded to the polyester film by the synchronous extruder, nitrogen is simultaneously sprayed for protection, certain cooling is simultaneously carried out, then the coating is uniformly coated, the coating is cooled to 70 ℃ by the nitrogen, then the polyethylene film is covered on the fluid for extrusion and fixation, and meanwhile, the liquid nitrogen is used for further cooling.
S3; and cutting the two side edges of the film of the pressed finished product by a cutting machine, winding by a winding machine to finish production, and storing in a closed environment.
Preferably, in step S2, a heater is disposed at the outlet of the extruder, and the mixed raw materials are heated to 190 ℃ during extrusion, so as to ensure the flowability of the extrusion.
Preferably, steps S1-S4 are all performed in a closed workshop, and dust removal is performed before each startup.
Preferably, a plurality of machine heads of the extruder are arranged, and one side of each machine head is provided with a scraper for scraping.
Preferably, during the compaction of step S2, the distance between the two press rolls is adjusted as needed
The invention has the beneficial effects that:
1: be connected the export of mixer with the extruder, can directly extrude after the stirring is accomplished, the work of cooperation heater simultaneously guarantees its mobility, and then guarantees the stability of holistic thickness, guarantees the stability of device simultaneously, and at the stirring in-process, directly extrudes simultaneously, guarantees the stability of compounding, and then the stability of assurance quality.
2: through the combination of a plurality of steps, can carry out stable production under stable space, guarantee each item operation of device, the going on of assurance processing.
Detailed Description
The described embodiments are only some embodiments of the invention, not all embodiments.
