Embodiment Construction

[0017] The described embodiments are only some, not all, embodiments of the present invention.

[0018] A dry film production process, comprising the following steps:

[0019] S1; add adhesive, photopolymerizable monomer, photoinitiator, plasticizer, thickener, thermal agglomeration agent, colorant and solvent into the mixing reaction kettle, heat to 110-170 degrees Celsius at the same time, stir and mix, Until all the raw materials are mixed evenly, at the same time, fix the polyester film and polyethylene film on one side of the device. During the production process, the whole device is carried out in a sealed workshop, and at the same time ensure that the production workshop is a dust-free environment. Under this condition, it can increase the overall fluidity, ensure the completion of mixing, and ensure the stability of the work during subsequent use. The polyester film is used as the bottom mold for foil, and the polyethylene film is used as the surface film for covering ...

Abstract

The invention discloses a dry film production process, relates to the technical field of dry film production, and provides the following scheme aiming at the problem that existing production has deviation. The dry film production process comprises the following steps that an adhesive, a photopolymerization monomer, a photoinitiator, a plasticizer, a thickener, a thermal polymerization inhibitor, apigment and a solvent are added into a mixed reaction kettle, and the mixture is heated to 110 DEG C-170 DEG C at the same time; stirring and mixing are performed until all the raw material are uniformly mixed, meanwhile, and a polyester film and a polyethylene film are fixed on one side of the device. According to the dry film production process, the extrusion can be directly performed after thestirring is completed, meanwhile, the work of a heater is matched so as to ensure the fluidity of a dry film, such that the stability of the whole thickness is ensured, meanwhile, the stability of adevice is ensured, Meanwhile, the direct extrusion is performed in the stirring process, material mixing stability is guaranteed, and then the quality stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of dry film production, in particular to a dry film production process. Background technique [0002] The dry film is relative to the wet film in the coating. The dry film is a polymer compound that can produce a polymerization reaction (the reaction process of synthesizing a polymer from a monomer) after being irradiated by ultraviolet rays to form a The stable substance adheres to the surface of the board, thereby achieving the function of blocking electroplating and etching. [0003] The existing dry film production generally adopts a three-layer design to carry out production, but the existing dry film production generally does not strictly control the environment, which makes the fluidity of the dry film during production poor, so that There is a certain deviation in the thickness and quality of the dry film production, and the follow-up work cannot be carried out well.
