Environment-friendly water-based composite wax emulsion release material for electric aluminum and preparation method of material

Abstract

The invention relates to the technical field of film coating products, and provides an environment-friendly water-based composite wax emulsion release material for electric aluminum and a preparation method of the material. The composite wax emulsion release material is characterized in that the composite wax emulsion release material is prepared from the following raw materials in parts by weight: 10-25 parts of montan wax, 2-8 parts of water-based resin, 2-7 parts of emulsifying agents, 1-5 parts of PH conditioning agents, 1-5 parts of wetting agents and 60-80 parts of water. Compared with the prior art, the composite wax emulsion release material has good alcohol tolerance; the composite wax emulsion release material is diluted with alcohol and water according to a ratio of 3:2, and then flocculated by a non-breaking emulsion, and wax particles coated on a film are distributed uniformly, so that the problem that the peeling effect of the wax emulsion release material is affected due to the fact that the coating quantity in a unit area is not stable is solved; water-based resin is matched reasonably, so that the surface tension of a coating layer is improved; the recoatability is excellent; the film coating appearance of a dark product is improved effectively; the water serves as a dispersion medium, so that the influence to the environment is little; the production cost is low; and the wax emulsion release material has the advantages of environmental protection and low cost.

Description

technical field [0001] The invention relates to the technical field of film coating products, and more specifically relates to a release material for anodized aluminum. Background technique [0002] Anodized aluminum is a multi-coated hot stamping material formed on a polyester film through a certain coating and vacuum aluminum plating process. The coatings from bottom to top are release layer, coloring layer, aluminum plating layer and bonding layer. The function of the release layer is to make the coatings quickly detach from the polyester film after hot stamping and transfer and bond on the surface of the hot stamped object. It must have good detachment performance, otherwise it will easily cause quality problems. [0003] Release materials generally include resins and waxes. [0004] The resin-type release material coating surface has a high surface tension, good recoatability, but poor cutability, not suitable for hot stamping of fine graphics and texts, and is mo...

Problems solved by technology

However, the wax emulsion has poor alcohol resistance, and it is easy to demulsify and flocculate during use, which not only causes waste, but also makes the wax particles coated on the polyester film unevenly distributed, and the coating amount per unit area is unstable, which affects its stripping effect. The quality problem of inconsistent product tightness occurs; the surface tension of the wax emulsion coating is small, and the recoatability is poor, especially dark-colored products are prone to film defects such as white spots, and there is also the problem of high cost of use
