Example Embodiment

[0034] Example

[0035] like Figure 1-10 As shown in the figure, the preparation process of negative ion environmentally friendly degradable vacuum blister plastic specifically includes the following operation steps:

[0036] S1: The material is preheated and liquefied, and the constituent materials of the vacuum suction plastic are pretreated first. The constituent materials of the vacuum suction plastic include: thermoplastic polyurethane elastomer rubber, thermoplastic polyurethane elastomer rubber, PUD emulsion, water-based closed isocyanate, water-based closed type Isocyanate, wherein the thermoplastic polyurethane elastomer rubber is placed in the screening assembly 3, and then the auxiliary device 1 is used to sieve the particle size of the material and segment the larger particles, and then the processed vacuum plastic composition material is subjected to high temperature. Heating makes the material of vacuum suction plastic change from solid to liquid;

Abstract

The invention discloses a preparation process of negative ion environment-friendly degradable vacuum blister glue. The preparation process specifically comprises the following operation steps: S1, preheating and liquefying a material; s2, material catalytic reaction; s3, a reinforcing material is placed; and S4, stirring and mixing the materials, the auxiliary device is used in the preparation process, so that the required materials can be subjected to large and small particle screening, and the relatively large materials are subjected to segmented treatment, so that the subsequent high-temperature liquefaction or mixing can be more efficient; the problem that heating is uneven during high-temperature treatment due to the fact that the material size difference is large during processing is avoided, and the effect after follow-up preparation is affected is solved, so that the performance of the vacuum plastic suction tape prepared through the preparation technology can be enhanced, and the performance of the vacuum plastic suction tape is improved by adding a reinforcing material in the preparation process. Compared with the prior art, the degradability of the vacuum plastic suction adhesive prepared by the preparation process is optimized.

Description

technical field [0001] The invention belongs to the field of plastic-absorbing glue preparation, and in particular relates to a negative-ion environment-friendly and degradable vacuum-absorbing glue preparation process. Background technique [0002] Vacuum plastic is a kind of water-based adhesive polyurethane glue. Water-based polyurethane glue is widely used in the market due to its water-based, non-toxic and convenient use. With people's pursuit of low-carbon and environmental protection, a series of water-based adhesives have been born. Among them, the existing vacuum plastics are not environmentally friendly, and cannot be effectively degraded after long-term use, which leads to the inability to be quickly processed after use. In the preparation technology, the materials cannot be sieved in sections, so it is easy to appear the problem of uneven heating during high temperature treatment due to the large size difference of materials during processing, and affect the sub...
