Problems solved by technology

However, the traditional hot-melt double-sided generally uses ordinary domestic cellophane, which is unstable in release and poor in moisture resistance, and the two-sided coating mainly uses the direct contact coating between the coating head and the substrate, and some substrates have poor temperature resistance and are easy to be heated. Destruction, the coating process is easy to break and shrink, causing a series of problems such as coating wrinkles or rubber surface wrinkles

Abstract

The invention relates to a glassine double-faced hot melting adhesive tape and a preparation method thereof. The preparation method comprises the following steps: S1: providing glassine, and carrying out distinctiveness releasing on double faces of the glassine through different release proportions to form glassine release paper, wherein the glassine paper is provided with a heavy release surface and a light release surface formed by the release proportions; S2: providing a base material, coating the heavy release surface, which is formed in S1, of the glassine with hot melting glue, compounding the glassine release paper with the base material through compound equipment, transferring the hot melting glue to the base material, and forming the glassine release paper of which one surface is coated with glue; S3: through the way of S1, preparing to obtain another glassine release paper, coating the light release surface of the glassine release paper with the hot melting glue, and transferring the glue to the light release surface of the glassine release paper through the compound equipment again; S4: stripping another glassine release paper.

Description

technical field [0001] The invention relates to a glassine paper double-sided hot-melt adhesive tape and a preparation method thereof. Background technique [0002] Glassine release paper is a paper with good internal strength and transparency made of Glassine special base paper after coating and processing. It is directly coated with silicon on the Glassine paper without coating, while other release paper Model paper needs to be coated with silicon first. The glassine release paper produced in this way has a series of characteristics such as high temperature resistance, impermeability, stable release force and high cleanliness. [0003] Glassine paper double-sided hot-melt tape uses glassine paper as the main raw material. Through glue coating and compounding, a double-sided glued glassine paper tape is obtained. The base material can be gauze, PET film, PP film, etc., which are made of this paper. The finished double-sided tape has good uniformity, beautiful appearance, ...
