Embodiment 1

[0060] 80 parts by weight of aliphatic urethane acrylate (Heshan Lizhimen, LE-6706, functionality is 6), and 10 parts by weight of isooctyl methacrylate and 10 parts by weight of hydroxyethyl methacrylate are mixed After uniformity, 4 parts by weight of phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide was added, and the mixture was stirred again to be uniform, and the operation should be protected from light to finally obtain a coating solution. Using the above-mentioned specific radiation curing device for making artificial leather release paper, the coating liquid is coated on the surface of the base paper by two-roller transfer coating twice. Base paper weight is 200g / m 2 , the width is 2000mm, and the thickness is 260μm. The coating amount of the first process is 50g / m 2 , UV curing, the wavelength is 370nm, the energy is 480w / cm, the coating amount of the second process is 100g / m 2 , solidified under the same conditions, and at the same time, patterned, the speed was c...

Embodiment 2

[0062] 60 parts by weight of aliphatic urethane acrylate (Shanghai Miki, the product of SM6621, with a functionality of 6), was mixed evenly with 20 parts by weight of isooctyl methacrylate and 20 parts by weight of hydroxyethyl methacrylate, Then add 6 parts by weight of phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, stir evenly again, pay attention to the operation in dark, and finally obtain the coating liquid. Using the above-mentioned specific radiation curing device for making artificial leather release paper, the coating liquid is coated on the surface of the base paper by two-roller transfer coating twice. Base paper weight is 150g / m 2 , the width is 2000mm, and the thickness is 200mm. The coating amount of the first process is 30g / m 2 , UV curing, the wavelength is 370nm, the energy is 300w / cm, and the coating amount of the second process is 70g / m 2 , solidify under the same conditions, and at the same time pattern forming, the speed of the vehicle is controlled...

Embodiment 3

[0064] Stir and mix 30 parts by weight of aliphatic urethane acrylate (Kesheng, Huizhou, UV613, with a functionality of 3) with 40 parts by weight of isooctyl methacrylate and 30 parts by weight of hydroxyethyl methacrylate, Then add 2 parts by weight of perphenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, stir evenly again, pay attention to the operation in dark place, and finally obtain the coating liquid. Using the above-mentioned specific radiation curing device for making artificial leather release paper, the coating liquid is coated on the surface of the base paper by two-roller transfer coating twice. Base paper weight is 120g / m 2 , the width is 2000mm, and the thickness is 150μm. The coating amount of the first process is 10g / m 2 , UV curing, the wavelength is 370nm, the energy is 100w / cm, and the coating amount of the second process is 10g / m 2 , solidify under the same conditions, and at the same time pattern forming, the vehicle speed is controlled at 100m / min, an...

Abstract

The invention discloses a method for making artificial leather release paper in a radiation curing manner. A device for making artificial leather release paper in a radiation curing manner is adopted in the method, and is sequentially provided with a first coating device, a first radiation curing device, a second curing device, a patterned roll and a second radiation curing device from an unreeling device and a reeling device, wherein the second radiation curing device covers on the patterned roll. The method comprises the following steps: (1) performing first-time coating on base paper by adopting a coating solution, and then performing first-time radiation curing to obtain the base paper on which a first coating is coated; and (2) performing second-time coating on the base paper on which the first coating is coated by adopting the coating solution, and then embossing by virtue of the patterned roll and performing second-time radiation curing to obtain the artificial leather release paper. The method disclosed by the invention comprises two procedures, and the coating solution is divided into two parts which are singly and respectively subjected to radiation curing, so that the curing rate can be improved, the travel speed is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of preparation of artificial leather release paper, in particular to a method for manufacturing artificial leather release paper by means of radiation curing. Background technique [0002] Artificial leather release paper, as the process paper in the production of synthetic leather, can give the surface of synthetic leather a pattern and feel comparable to genuine leather, and is a carrier and temporary mold in the production of synthetic leather. The specific production method is roughly as follows: first coat a layer of release resin layer on the surface of base paper, and then emboss the release resin layer after curing to obtain artificial leather release paper with patterns on the surface. [0003] The traditional curing method is mostly thermal curing, which has many disadvantages, such as slow curing speed, high energy consumption, complicated process, and high temperature treatment is likely to cause curling, ...
