Embodiment 1

[0060] A water-based non-silicon release paper includes a substrate layer and a release layer, and the release layer is composed of a water-based non-silicon release agent and water. The water-based non-silicon release agent is octadecyl urethane 3-hydroxy polyacrylate, and the release layer is obtained by coating a 3-15% aqueous solution of the water-based non-silicon release agent on the substrate layer. The substrate layer includes a base paper layer and a PET plastic film layer, and the water-based non-silicon release paper is a release layer, a PET plastic film layer, and a base paper layer from top to bottom.

[0061] The main raw materials for the preparation of water-based non-silicon release agent include: 3-formyl propionic acid, carbamic acid, n-stearyl alcohol; the chemical name of water-based non-silicon release agent is: octadecyl carbamic acid 3-hydroxy polyacrylate ;

[0062] The preparation of octadecyl urethane 3-hydroxy polyacrylate mainly includes the foll...

Embodiment 2

[0088] The shape and structure of this embodiment is similar to that of embodiment 1, the only difference is that the substrate layer is slightly different, and two release layers are provided. A kind of water-based non-silicon release paper of this embodiment, the substrate layer includes a base paper layer and two PET plastic coating layers, and the water-based non-silicon release paper is a release layer and a PET plastic coating layer from top to bottom. , Base paper layer, PET plastic coating layer, release layer.

Embodiment 3

[0090] The shape and structure of this embodiment and embodiment 1 are basically the same, the difference is only that in the preparation method of the water-based non-silicon release paper, the process parameters in step 2, step 3 and step 7 are slightly different. In step 2, after mixing 3-formylpropionic acid with water, add an initiator, and change the reaction time at 2atm and 30°C to 15min; The degree of vacuum is changed to -0.06Mpa; in step 7, the temperature of dehydration is changed to 120°C, and the degree of vacuum of dehydration is changed to -0.06Mpa.

Abstract

The invention relates to the field of release materials, in particular to a water-based non-silicon release agent and a preparation method thereof and water-based non-silicon release paper. The water-based non-silicon release agent comprises a base material layer and a release layer, and the release layer is composed of the water-based non-silicon release agent and water. The chemical name of thewater-based non-silicon release agent is octadecyl carbamic acid 3-hydroxy polyacrylate, and in the preparation method of the water-based non-silicon release agent, the main raw materials comprise 3-aldehyde propionic acid, carbamic acid and n-octadecanol, and the preparation method comprises seven reaction steps in total. The water-based non-silicon release paper can be widely applied to variousfields, is greener and more environment-friendly, and does not have the phenomenon of silicon transfer in the fields of application and electronic product production, especially in the field of FPC production; the preparation method of the water-based non-silicon release agent is high in raw material utilization rate, and the obtained product is high in purity; and the water-based non-silicon release agent disclosed by the invention can be used for improving relatively good release force for release paper, so that the release paper is relatively good in release.

Description

technical field [0001] The invention relates to the field of release materials, more specifically, it relates to a water-based non-silicon release agent, a preparation method thereof and a water-based non-silicon release paper. Background technique [0002] The release paper is a kind of anti-adhesive paper that prevents the prepreg from sticking and can protect the prepreg from contamination. It is mainly used in the fields of silica gel production, FPC production and other fields. At present, there are various types of release paper, mainly silicone oil release paper, silicone oil release film, waxed paper, special plastic release film, etc. [0003] Among them, the silicone oil centrifugal paper includes a silicone oil layer, a base paper layer, and a plastic coating layer arranged in sequence from top to bottom. The preparation method mainly includes two steps of coating silicone oil on one side of the base paper and coating the plastic coating on the other side. Silico...
