Embodiment 1
[0041] A kind of release oil for plastics, it is prepared by following steps:
[0042] According to the dosage shown in Table 1, add component A and component B to the agitator, stir and mix evenly to obtain mixed liquid a, and set aside; add liquid cane wax and ethanol to another agitator, stir and mix evenly to obtain C component;
[0043] In the state of stirring, add components C and D into the mixture a in sequence, stir and disperse for 2 minutes to obtain the mixture b;
[0044] Add adhesion enhancer to mixture b, stir and disperse at 1000r / min for 2h until no precipitation; add stabilizer, grind once at a grinding speed of 300L / h to obtain mixture c;
[0045] Stir ethanol, water, liquid cane wax and isopropanol evenly to obtain component F, which is set aside;
[0046] In the state of stirring, add component E and component F to the mixture c in sequence, and stir and disperse evenly at 1000r / min to obtain the release oil for finished plastics.
Embodiment 2
[0048] The difference between Example 2 and Example 1 is: add an adhesion enhancer to the mixture b, stir for 5 minutes at 1000r / min, grind three times at a grinding speed of 300L / h to a fineness of 5μm; add a stabilizer, stir Disperse for 5 minutes, grind once at a grinding speed of 300 L / h, so that the fineness of the mixture is not greater than 5 μm, and obtain mixture c; the rest are the same as in Example 1.
Embodiment 3
[0050]The difference between Example 3 and Example 1 is: Add adhesion enhancer to mixture b, stir and disperse at 1000r / min for 5min, grind at 300L / h grinding speed four times until the fineness reaches 5μm; then add Stabilizer, all the other are identical with embodiment 1.

Abstract
This application relates to the technical field of food plastic packaging, in particular to the processing technology of plastic release oil, dry mix instant food bowl cover and dry mix instant food bowl cover. The plastic release oil consists of the following raw materials in weight percentage Prepared: A component: alcohol-soluble polyurethane resin 7-13%; B component: isopropanol 3-8%; C component: liquid cane wax 2-5%, ethanol 10-15%; D component : water 3‑8%; adhesion enhancer 7‑13%; stabilizer 0.05‑0.2%; E component: alcohol-soluble polyurethane resin 15‑23%; F component: ethanol 5‑10%, water 3‑8% , liquid sucrose wax 8‑13% and isopropanol 8‑15%; release oil for plastics has good adhesion and leveling properties, and has a good release effect after printing on the release area of the bowl cover; using this The dry-mix instant food bowl lid obtained after printing with release oil has good peeling performance in the tearable area, hole drop and hole residue are up to the standard, and there is no transfer in the release area, and the comprehensive performance is excellent.
Description
technical field [0001] The application relates to the technical field of food plastic packaging, in particular to a release oil for plastics, a processing technology of a dry mix instant food bowl cover and a dry mix instant food bowl cover. Background technique [0002] Bowl-packed dry-mixed noodles, hot-dried noodles, sauce-mixed noodles and other dry-mixed instant noodles are popular among people for their convenience and variety of flavors. In order to improve the tightness in the dry mixing instant food bowl during soaking with water, the dry mixing instant food bowl is provided with a matching sealing bowl cover. [0003] The lid of the dry mix instant food bowl is mostly made of a multi-layer structure composed of plastic and aluminum foil. One side of the bowl cover can be torn off. Seal it on the top surface of the bowl, so that the dry noodles are soaked in hot water and softened during the soaking process. Before eating, the above-mentioned torn part is opened a...
