Problems solved by technology

[0002] With the rapid development of industry, many products need to use sheet-shaped tapes. There are many types of sheet-shaped tapes on the market, which are suitable for various commodities. However, the waterproof performance of traditional sheet-shaped tapes is not ideal, which often makes products The occurrence of wet conditions will affect the quality and normal use of the product, and, after a long period of use, its viscosity will become smaller and smaller

Embodiment 1

[0026] The processing technology of the sheet-shaped tape includes the following processing steps:

[0027] S1. Prepare the base layer: select a PE film with a thickness of 0.3 mm, and perform static removal pretreatment on the PE film;

[0028] S2. Preparation of waterproofing agent: Add polypropylene, polyvinyl alcohol and silicone resin into the reactor at a mass ratio of 5:2:1, slowly raise the temperature of the reactor to 80°C, and keep stirring to fully mix the three, after stirring for 30 minutes , take out, and cool to room temperature;

[0029] S3. Preparation of viscose: add vinyl acetate and acrylic acid to the reactor, slowly raise the temperature of the reactor to 100~115°C, stir for 10~20min, add butyl acrylate, wherein the mass ratio of vinyl acetate, acrylic acid and butyl acrylate The ratio is 3:2:6, and the temperature rises slowly to 125°C under constant stirring; divide the auxiliary agent into 3 equal parts, add the first auxiliary agent, slowly raise th...

Abstract

The invention discloses a process for processing a sheet-shaped adhesive tape. The process is characterized by comprising the following steps: preparing a substrate, preparing a waterproofing agent, preparing adhesive, coating a protective film, coating an adhesive layer, adhering release paper, coating a wear layer and cutting to finally prepare the sheet-shaped adhesive tape finished product. The process for processing the sheet-shaped adhesive tape is simple in process, convenient to operate and low in production cost; and the prepared sheet-shaped adhesive tape has excellent adhesion, waterproofing performance, abrasion resistance and excellent use strength.

Description

technical field [0001] The invention relates to the technical field of tape processing, in particular to a processing technology of a sheet-shaped tape. Background technique [0002] With the rapid development of industry, sheet-shaped tapes are required for many products. There are many types of sheet-shaped tapes on the market, which are suitable for various commodities, but the waterproof performance of traditional sheet-shaped tapes is not ideal, which often makes products The occurrence of wet conditions will affect the quality and normal use of the product, and, after a long period of use, its viscosity will become smaller and smaller. Therefore, research on improving the waterproof performance and stickiness of sheet-shaped tapes is necessary. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a processing of sheet-shaped tape with simple process, convenient operation and low pro...
