Problems solved by technology

[0002] At present, the surface of common coated paper (including release paper) on the market only has glossy surface and matte surface. When people use this traditional coated paper to make pressure-sensitive adhesive label paper, the surface is smooth and flat. The beautification effect is not ideal; and in the process of making the coated release paper, it is not easy to cut because of its flat surface and no reference lines. When the adhesive label paper is pasted, air bubbles are likely to form between the two, which will affect the use effect
In the prior art, some people have used traditional cold pressing and hot pressing methods for embossing, but the effect of the lines produced is not satisfactory, either deep or shallow, and the distribution of lines is extremely uneven, and the Operators have high technical requirements, low production efficiency, and a lot of waste. In view of the above shortcomings, it is necessary to improve the process

Embodiment Construction

[0011] A kind of manufacture technology of embossed coating release paper, it is characterized in that comprising the following steps:

[0012] 1) Preparation of laminating coating

[0013] Put the high-density polyethylene and low-density polyethylene into the mixing container according to the weight ratio of 1:1.5-2, mix and stir for 5-10 minutes to make the two evenly mixed, and extrude the feeding screw in the system through the laminating machine Heating and bridging at 180-245°C to melt the polyethylene mixture to achieve sufficient bridging to facilitate the strengthening of molecular chain links, and then further heating the polyethylene mixture to 310-360°C on the feed screw to make it a molten fluid Shape and pressurize to 5Mpa-20Mpa at the same time, when the polyethylene mixture passes through the outlet of the screw, a die head heats the polyethylene mixture at 320-360°C, and turns it into a cloth shape and extrudes it.

[0014] 2) Preparation of embossed film re...

Abstract

The invention discloses a production technology of embossing laminating release paper, the production technology is characterized by comprising the following steps: 1) preparing laminating paint, adding the high-density polyethylene and the low-density polyethylene into a stirring vessel to mix and stir for 5-10 minutes to mix evenly, the weight ratio of the high-density polyethylene and the low-density polyethylene is 1:1.5-2, and then heating, bridging, heating and melting, pressing and extruding the mixture. 2) preparing the embossing laminating release paper, laminating the extruded polyethylene mixture to the surface of the paper by a composite wheel, pressing and compositing the mixture by the composite wheel, and cooling the temperature at 30-40 DGE C after compositing, continually moving the paper after laminating driven by a roller and cooling the paper at the temperature of 12-20 DGE C, and side cutting, rolling, packaging for the paper, finally, coating silicon oil on the surface of the laminating paper to prepare the finished product of the embossing laminating release paper. The invention has convenient production technology; the embossing laminating release paper prepared by the production technology has the advantages of beautiful shape and good use effect, can be widely used in the technology of manufacturing the embossing laminating release paper.

Description

technical field [0001] The invention relates to a production process of release paper, in particular to a production process of embossed film release paper. Background technique [0002] At present, the surface of common coated paper (including release paper) on the market only has glossy surface and matte surface. When people use this traditional coated paper to make pressure-sensitive adhesive label paper, the surface is smooth and flat. The beautification effect is not ideal; and in the process of making the coated release paper, it is not easy to cut because of its flat surface and no reference lines.
