More particularly, the present invention relates to a panel- The present invention relates to a panel-integrated functional sheet and a method for manufacturing the panel-integrated functional sheet, in which not only the efficiency of operation but also the economical advantage is maximized because the operation related work for attaching the film can be omitted.
In general, electrostatic discharge (ESD) is a very important factor in the electronics industry, and customers in the semiconductor and electronics industries are demanding plastics with antistatic properties that are further translucent to better transparency .
On the other hand, technologies for reducing electrostatic discharge are provided through various means such as grounding, antistatic film, air ionization, and charge dispersion material.
Adding a conductive metal or carbon to a thermoplastic resin can provide conductivity but is difficult to control with a conductivity level suitable for the electronic or semiconductor industry. The transparency of the polymer decreases with the addition of fillers, but the addition of a small amount of filler may affect the optical properties of the polymer.
In recent years, a small amount of antistatic fine particles are added to the polymer matrix.
These antistatic agents are hygroscopic raw materials that increase the surface conductivity by moving to the surface of the plastic, absorbing moisture and forming a layer on the surface of the polymer, and as time passes, the antistatic fine particles decrease during polishing of the polymer surface Eventually, the conduction characteristic is lost.
In addition, the existing products used in the photomask packaging material and storage case were seriously damaged by static electricity and harmful OUT-GAS, which could damage the photomask chrome pattern and adversely affect the whole product. As a result, due to quality problems and production cost problems, production is stopped and existing packaging materials and storage case companies are urgently required to replace them with raw materials.

Thereafter, the extruder screw And the mixture was moved by 180 mm by an extruder screw heated to a temperature of 250 DEG C and mixed by a secondary mixer. The extruder screw was heated at a temperature of 250 DEG C by an extruder screw to move the extruder by 80 mm, A product discharging step for discharging the extruded product to the outside through the extruder screw heated by the extruder screw heated to a temperature of 240 to 250 ° C through a conveying section in a die direction of the screw; A pellet forming step of cutting a pellet with a length of 2 to 3 mm and a thickness of 1.0 to 1.5 mm and a PANEL having an antistatic function to form a pellet on one or both sides of the panel, And a panel integrating step in which the panel is integrated with a pellet by interposing a pellet by pressing with a press machine.
