Abstract

The invention discloses a waterborne release agent. The waterborne release agent is characterized by being prepared from the following components in percent by weight: 10-40% of a paraffin emulsion, 5-35% of a palm wax emulsion, 20-60% of a polytetrafluoroethylene emulsion, and 0.5-2% of an organic silicone surfactant; and the sum of the weight percentages of the above components is 100%. The invention also discloses a preparation method and a construction method of the waterborne release agent. The waterborne release agent is used for a substrate, the surface of the substrate after release does not have printing ink or ink residue, the waterborne release agent has no addition of organic solvents and no VOC emission, and is environment-friendly and low in cost, and the raw materials are human-friendly, so that the waterborne release agent can be applied to human body contactable fields.

Description

technical field [0001] The invention relates to a release agent, in particular to a water-based release agent and a preparation method and a construction method thereof. Background technique [0002] The release agent is to prevent the formed composite product from sticking to the mold, and a type of isolation film is applied between the product and the mold, so that the product can be easily released from the mold, while ensuring the surface quality of the product and the mold are intact. [0003] In recent years, thermal transfer printing technology has received widespread attention at home and abroad. Among them, the release agent is the core content of thermal transfer printing technology, and it is the decisive factor whether the ink can be fully attached to the surface of the substrate. The release agent plays the role of buffering the adhesion between the PET film and the printing layer, and has good abrasion resistance, which can protect the color ink and prolong th...
