High-brightness release paper, and preparation method and applications thereof

Abstract

The invention discloses a high-brightness release paper, and a preparation method and applications thereof. The high-brightness release paper is composed of base-material-layer base paper (1), a film layer (2), an adhesive layer (3), a film layer (4) and a release layer (5), wherein the film layer (2) is sprayed on one side of the base paper (1), the adhesive layer (3) is coated on the other side of the base paper (1), the film layer (4) is attached to the adhesive layer (3), and the release layer (5) is coated on the film layer (4). The high-brightness release paper of the invention has favorable surface smoothness and residual adhesion force. The adhesive sticker prepared from the release paper of the invention has favorable adhesive surface smoothness, and thus, the invention can solve the technical problem of inadequate adhesive surface smoothness (blushing) of the adhesive stickers. The preparation method of the release paper has the advantages of reasonable technical design, high operability, high production efficiency and high finished-product pass rate, and can realize industrial mass production.

Description

Technical field [0001] The invention relates to a release paper, in particular to a high-gloss release paper with high surface flatness and good residual adhesive force. The invention also relates to a preparation method of the high-gloss release paper and its application. Background technique [0002] The traditional release material is generally coated with a PE coating layer (commonly known as coated paper) on the surface of the base paper, and then a layer of release agent is coated on the surface of the PE coating layer to obtain the release material. Among them, the PE coating layer is to melt the PE particles and pour it on the surface of the base paper with a die. Therefore, the surface flatness of the base paper has a great influence on the flatness of the coating layer, and the structure of the base paper determines its surface flatness. Uniformity. For example, the surface flatness of the coated paper is not high, and the surface flatness of the release paper made afte...

AI Technical Summary

Problems solved by technology

Among them, the PE coating layer is melted PE particles and sprayed on the surface of the base paper with a die head, so the surface flatness of the base paper has a great influence on the flatness of the coating layer, and the structure of the base paper determines that its surface flatness is difficult. Even, if the surface flatness of coated paper is not high, the surface flatness of the release paper made after coating the release agent is also very poor. The flatness of the adhesive surface of self-adhesive products is also very poor, because the acrylic adhesive used in self-adhesive products has strong creepability when it is not fully cured. When the surface flatness of the release paper is poor, it will not dry. After the adhesive product is bonded with the release paper, the lines on the surface of the release paper will be printed on the rubber surface. At this time, the adhesive has not been completely cured. When the adhesive is completely cured, the lines formed cannot be eliminated, resulting in insufficient flatness of the rubber surface. (i.e. fogging)
