Embodiment 1

[0041] A kind of high-efficiency and energy-saving double-sided coating release paper coating process of this embodiment, such as figure 1 shown, including the following steps:

[0042] (1) After the unwinding mechanism 6 releases the base material 5, the front corona device 7 is used to polarize one side of the base material, and after completion, the polarized side of the base material is sprayed by the front surface coating device 8. Membrane, forming the frontal barrier;

[0043] (2) puncture the front isolation layer by the punching device 8, so that air-permeable micropores are formed on the front isolation layer;

[0044] (3) Carry out polarization treatment to the other side of base material by back side corona device 10, carry out film coating by back side coating device 11 after completion, form back side isolation layer;

[0045] (4) Rewinding is carried out by the winding mechanism 13 after completion.

[0046] During the extrusion coating process, due to the addi...

Embodiment 2

[0058] A kind of high-efficiency and energy-saving double-sided coating release paper coating process of this embodiment, such as Figure 6 shown, including the following steps:

[0059] (1) After the unwinding mechanism 6 releases the base material, the front corona device 7 is used to polarize one side of the base material, and after completion, the front side coating device 8 is used to coat the polarized side of the base material. , forming a positive isolation layer;

[0060] (2) Polarization is carried out to the other side of base material by back side corona device 10, after completion, carry out film coating by back side coating device 11, form back side isolation layer;

Abstract

The invention discloses a high efficient energy-saving coating technology and equipment of a double side coated release paper. According to the technology, an isolation layer is formed on one side ortwo sides of a substrate, then the isolation layer on one side of the substrate is punched to form a hole by a hole punching device so that a release agent can be painted on the isolation layer on theother side, and after the isolation layer on the other side is painted, the substrate is reeled by a reeling mechanism. The equipment comprises following components, which are sequentially connectedalong the substrate delivery direction: an unreeling direction, a front corona device, a front coating device, a hole punching device, a rear corona device, a rear coating device, a silicon painting device, and a reeling device; or comprises following components, which are sequentially connected along the substrate delivery direction: an unreeling mechanism, a front corona device, a front coatingdevice, a rear corona device, a rear coating device, a hole punching device, and a reeling device. The product quality is guaranteed, the drying step is eliminated, the production energy consumption and equipment cost are reduced, and the goals of environmentally friendly production, high efficiency and energy saving are realized.

Description

technical field [0001] The invention relates to the technical field of release paper manufacturing, in particular to a high-efficiency and energy-saving double-sided coated release paper coating process and equipment. Background technique [0002] Release paper, also known as release paper, anti-adhesive paper, silicone oil paper, etc., is a kind of anti-adhesive paper that can prevent prepreg from sticking and protect prepreg from contamination. Release paper is mainly composed of substrate layer, isolation layer and release layer. Among them, the substrate layer plays the supporting and printing functions, and generally chooses 60g / m 2 For the above paper, it is necessary to control the bulkiness and heat resistance of the base paper; the function of the isolation layer is to prevent the release agent from penetrating into the paper, and separate the base layer of the paper from the release agent layer. The main processing methods currently include the coating method ( A...
