preparation example Construction

[0023] The preparation process of the above-mentioned biodegradable silent sealing tape, such as figure 2 shown, including the following steps:

[0024] S1. Provide a biodegradable plastic film and make it into a strip-shaped substrate.

[0025] In this step, the biodegradable plastic film made from one or more raw materials of starch, cellulose and chitin is selected, and the specific preparation process is as follows:

[0026] First, starch, cellulose, chitin and other raw materials are fermented to produce lactic acid, and then the lactic acid is converted into polylactic acid plastic granules (PLA granules) through chemical synthesis; secondly, the PLA granules are fed into the extruder and processed at 140 Under the action of ~160℃ and screw shearing, melt and plasticize, extrude and then filter to remove impurities; secondly, put the plasticized polylactic acid into the T-shaped die to form a sheet material, which is cooled Then, it is preheated by the longitudinal st...

Embodiment 1

[0041] A preparation process of a biodegradable silent sealing tape ring:

[0042] S1. First, 50 kg of starch is fermented to make lactic acid, and then the lactic acid is converted into PLA particles through chemical synthesis; secondly, the PLA particles are fed into the extruder, and melted at 150°C and under the action of screw shear. After plasticizing and extruding, filter to remove impurities; secondly, put the plasticized polylactic acid into the T-shaped die to form a sheet material, and the sheet material is cooled and then preheated by a longitudinal stretching machine for longitudinal stretching ; Finally, it is sent to a horizontal drawing machine for transverse stretching to obtain a biodegradable plastic film.

[0043] S2. Corona treatment is carried out on the two surfaces of the biodegradable plastic film substrate respectively, and the surface energy of the outer surface to be coated with silicone oil is controlled to be 52 dyne; for the other surface, the su...

Embodiment 2

[0051] A preparation process of a biodegradable silent sealing tape ring:

[0052]S1. Ferment 30 kg of cellulose and 20 kg of chitin to produce lactic acid, and then convert the lactic acid into PLA particles through chemical synthesis; secondly, feed the PLA particles into the extruder and heat them at 160°C and under the shearing conditions of the screw. Under the action, it melts, plasticizes, extrudes, and then filters to remove impurities; secondly, the plasticized polylactic acid enters the T-shaped die to form a sheet material, which is cooled and then preheated by a longitudinal stretching machine Longitudinal stretching is carried out; finally, it is sent to a horizontal stretching machine for transverse stretching to obtain a biodegradable plastic film.

[0053] S2. Corona treatment is performed on the two surfaces of the biodegradable plastic film base material respectively, and the surface energy of the outer surface to be coated with silicone oil is controlled to ...

Abstract

The invention discloses a biodegradable silent packing tape which comprises a release layer, a substrate and an adhesive layer which are successively laminated, wherein the release layer is made from silicone oil, and the substrate is a biodegradable plastic film. According to the packing tape which takes the biodegradable material as the substrate, the substrate can be fully decomposed through decomposition effect of microorganisms (bacteria, moulds / fungi and algae) in a natural environment so as to eliminate the environmental pollution after wastes. Meanwhile, the release layer made from silicone oil is arranged on the surface of the substrate, so that noise pollution generated by peeling can be avoided if being used.

Description

technical field [0001] The invention relates to a preparation method of an adhesive tape, in particular to a biodegradable silent sealing tape and a preparation method thereof. Background technique [0002] Due to the rapid development of the logistics industry, sealing tape is widely used. However, a large part of the existing sealing tapes is still made of non-degradable substrates, causing serious environmental pollution. [0003] There are currently many studies on biodegradable sealing tapes, but few of them can be directly inorganicized in the natural environment after the products are discarded and become natural components. [0004] In addition, during the use of the existing sealing tape, there will be a loud tearing sound when the tape is separated, causing sound pollution. Contents of the invention [0005] Based on the above problems, the object of the present invention is to provide a preparation method of biodegradable silent sealing tape. [0006] Technic...
