Embodiment 1

[0014] The present invention proposes a kind of coating release paper manufacturing process with wear resistance, comprising the following steps:

[0015] S1: To prepare the first coating material, put EVA resin, ethylene propylene rubber, and silicon carbide into the mixer according to the mass ratio of 1:0.1:0.02 and mix and stir for 10 minutes to make it evenly mixed for later use. The mixture enters the screw through the feed port of the first laminating machine for heating and bridging to obtain a molten EVA resin mixture mixed with ethylene-propylene rubber and silicon carbide. The heating bridging temperature is 80 degrees Celsius, and then the feeding screw Continue to heat the molten EVA resin mixture to 160 degrees Celsius to make the EVA resin into a molten fluid state, and apply a pressure of 5 MPa. After the EVA resin fluid mixture is threaded out, it passes through the die to form a network. squeeze out

[0022] The present invention proposes a kind of coating release paper manufacturing process with wear resistance, comprising the following steps:

[0023] S1: To prepare the first coating material, put EVA resin, ethylene propylene rubber, and silicon carbide into the mixer according to the mass ratio of 1:0.2:0.03, and mix and stir for 15 minutes to make it evenly mixed for later use. The mixture enters the screw through the feed port of the first laminating machine for heating and bridging to obtain a molten EVA resin mixture mixed with ethylene-propylene rubber and silicon carbide. The heating bridging temperature is 90 degrees Celsius, and then the feeding screw Continue to heat the molten EVA resin mixture to 165 degrees Celsius to make the EVA resin into a molten fluid state, and apply a pressure of 6 MPa. After the EVA resin fluid mixture is threaded out, it passes through the die to form a network. squeeze out

[0030] The present invention proposes a kind of coating release paper manufacturing process with wear resistance, comprising the following steps:

[0031] S1: To prepare the first coating material, put EVA resin, ethylene propylene rubber, and silicon carbide into the mixer according to the mass ratio of 1:0.3:0.04 and mix them for 20 minutes to make them evenly mixed for later use. The mixture enters the screw through the feed port of the first laminating machine for heating and bridging to obtain a molten EVA resin mixture mixed with ethylene-propylene rubber and silicon carbide. The heating bridging temperature is 100 degrees Celsius, and then the feed screw Continue to heat the molten EVA resin mixture to 170 degrees Celsius to make the EVA resin into a molten fluid state, and apply a pressure of 7 MPa. After the EVA resin fluid mixture is threaded out, it passes through the die to form a network. squeeze out

Abstract

The invention discloses a manufacturing technology for film release paper with the wear resistance. The technology comprises the following steps of preparing a first film material, forming a net shapethrough a die head for extrusion to prepare a second film material, forming a cloth shape through the die head for extrusion, selecting body paper for performing corona pretreatment, removing fiber and paper lint on the body paper, introducing the treated body paper into a composite wheel of a first film machine, enabling the film to reach the surface of the paper, forming a first film layer on the surface of the paper, after first-time film cooling, introducing the paper to a composite wheel of a second film machine, enabling the film to form a second film layer on the first film layer, after compositing, after cooling of the wheels, performing slitting according to the requirement of a client, and finally coating the surface of the second film layer of the paper with a silicone oil layer to form the film release paper with the wear resistance. The wear resistance of the release paper is effectively enhanced, and the film release paper has the higher adhesive power.

Description

technical field [0001] The invention relates to the technical field of release paper, in particular to a production process of a coated release paper with wear resistance. Background technique [0002] Coated paper is a composite material in which plastic particles are coated on the surface of paper through a casting machine. The main feature is that this composite material can be oil-proof, waterproof (relatively), and can be heat-sealed. Different uses take different characteristics, and are widely used in office paper, food packaging, leather shoe materials and other anti-sticking materials. At present, the common coated release paper on the market is generally coated with a layer of polyethylene. In the process of using the coated release paper, it does not have wear resistance and is easy to wear during use. For this reason, we propose a production process of coated release paper with wear resistance. Contents of the invention [0003] The present invention proposes...
