Embodiment 1

[0027] A preparation method for reflective film protective tape, comprising the following steps:

[0028] Step 1: mixing 2 parts by weight of acrylic acid, 17 parts by weight of isooctyl acrylate, 7 parts by weight of butyl acrylate, 5 parts by weight of vinyl acetate and 49 parts by weight of ethyl acetate;

[0029] Step 2: Turn on the mixer, control the speed at 25 rpm, heat up to 80°C, start titration of the titration solution prepared by 0.2 parts by weight of BPO and 8 parts by weight of ethyl acetate, titrate for 20 minutes, and the temperature rises to 85°C, stop titration;

[0030] Step 3: Start to cool down, and continue titration when the temperature drops to 80°C. It takes 100 minutes. After titration, keep warm for 4 hours to cool down and remove the glue; get the protective glue for the finished reflector;

[0031] Step 4: Unglue: put 5 parts by weight of modified terpene phenol resin and 5 parts by weight of carbon 9 resin into 100 parts by weight of protective ...

Embodiment 2

[0034] A preparation method for reflective film protective tape, comprising the following steps:

[0035] Step 1: mixing 5 parts by weight of acrylic acid, 20 parts by weight of isooctyl acrylate, 10 parts by weight of butyl acrylate, 8 parts by weight of vinyl acetate and 52 parts by weight of ethyl acetate;

[0036] Step 2: Turn on the mixer, control the speed at 25 rpm, heat up to 80°C, start titration of the titration solution prepared by 0.3 parts by weight of BPO and 8 parts by weight of ethyl acetate, titrate for 20 minutes, and the temperature rises to 86°C, stop titration;

[0037] Step 3: Start to cool down, and continue titration when the temperature drops to 80°C. It takes 100 minutes. After titration, keep warm for 4 hours to cool down and remove the glue; get the protective glue for the finished reflector;

Abstract

The invention relates to a reflective sheet protection glue and a reflective sheet protection glue tape, and preparation methods thereof, and belongs to the technical field of glue tape processing. The reflective sheet protection glue is prepared from, by weight, 2-5 parts of acrylic acid, 17-20 parts of isooctyl acrylate, 7-10 parts of butyl acrylate, 5-8 parts of vinyl acetate, 57-60 parts of ethyl acetate and 0.2-0.3 part of BPO. The reflective sheet protection glue has the advantages of high initial sticking property, high retention property and good stripping performance.

Description

technical field [0001] The invention belongs to the technical field of adhesive tape processing, and in particular relates to a reflective film protective glue, an adhesive tape and a preparation method thereof. Background technique [0002] The reflective sheet is composed of a transparent sheet capable of reflecting through its back. The transparent sheet has a front part or all of which is composed of multiple composite surfaces. Each composite surface is composed of a cylindrical surface inclined only in one direction and Composed of curved surfaces or planes inclined in the opposite direction, the above-mentioned composite surface is either continuous or interposed with a plane, and its structure is that the cylindrical surface occupies most of the area of ​​the composite surface, and the above-mentioned transparent sheet also has a plurality of Adjacent to the back side formed by the rectangular prism. [0003] In order to improve the utilization efficiency of light, ...
