Embodiment 1

[0021] A strong double-sided adhesive tape obtained by uniformly applying an adhesive to both sides of a plastic film base. The adhesive consists of nano-montmorillonite suspension, yam surface mucus, and benzyl chloroformate in a mass ratio of 10:1:0.1. It is made by high-speed dispersion of polyurethane prepolymer after mixing;

[0022] The preparation method of the mucus on the surface of the yam is as follows: peel the fresh yam, cut it into slices, mix it with water evenly in a mass ratio of 1:5, add ethanol with 10% of the mass of the yam, and perform beating for 30 minutes at a beating speed of 800r / min, then filter to obtain the filtrate, reclaim the ethanol in the filtrate, then add its quality 0.12% myristic acid in the filtrate, after stirring, leave standstill for 2 hours, then concentrate to 1 / 10 of the original volume, i.e. have to.

[0023] The preparation method of the adhesive is specifically:

[0024] (1) After mixing the raw materials polyester polyol and...

Embodiment 2

[0034] A strong double-sided adhesive tape is obtained by applying an adhesive evenly to both sides of a plastic film base. The adhesive consists of nano-montmorillonite suspension, yam surface mucus, and benzyl chloroformate in a mass ratio of 12: 2: 0.3 It is made by high-speed dispersion of polyurethane prepolymer after mixing;

[0035] The preparation method of the mucus on the surface of the yam is as follows: after the fresh yam is peeled, it is cut into slices, after being uniformly mixed with water in a mass ratio of 1: 7, the ethanol with 10% of the yam quality is added, and beating is performed for 35 minutes at a beating speed of 800r. / min, then filter to obtain the filtrate, reclaim the ethanol in the filtrate, then add its quality 0.15% myristic acid in the filtrate, after stirring, leave standstill for 2 hours, then concentrate to 1 / 10 of the original volume, i.e. have to.

[0037] (1) After mixi...

Embodiment 3

[0047] A strong double-sided adhesive tape obtained by uniformly applying an adhesive to both sides of a plastic film base. The adhesive consists of nano-montmorillonite suspension, yam surface mucus, and benzyl chloroformate in a mass ratio of 11:1:0.2. It is made by high-speed dispersion of polyurethane prepolymer after mixing;

[0048] The preparation method of the mucus on the surface of the yam is as follows: peel the fresh yam, cut it into slices, mix it evenly with water in a mass ratio of 1:6, add ethanol with 10% of the mass of the yam, and perform beating for 32 minutes at a beating speed of 800r / min, then filter to obtain the filtrate, reclaim the ethanol in the filtrate, then add its quality 0.14% myristic acid in the filtrate, after stirring evenly, leave standstill for 2 hours, then concentrate to 1 / 10 of the original volume, i.e. have to.

Abstract

The invention discloses a powerful double-sided adhesive tape and relates to the field of double-sided adhesive tapes. The powerful double-sided adhesive tape is prepared through uniformly coating both sides of a plastic film base layer with an adhesive, wherein the adhesive is prepared through mixing a nano-montmorillonite suspension, rhizoma dioscoreae surface slime and carbobenzoxy chloride, which are in the mass ratio of (10 to 12): (1 to 2): (0.1 to 0.3), and then, carrying out high-speed dispersion on a polyurethane prepolymer. The powerful double-sided adhesive tape disclosed by the invention has good water resistance and can be used in a long term in wet or water-including environments without adhesion property lowering; and the powerful double-sided adhesive tape is good in stability and dispersity, is pollution-free and odor-free and is free of influence on human health.

Description

technical field [0001] The invention belongs to the technical field of double-sided adhesive tapes, in particular to a strong double-sided adhesive tape. Background technique [0002] Double-sided tape is a special paste supplies. Double-sided adhesive tape is generally a roll-shaped adhesive tape made of paper, cloth, or plastic film as the base material, and then uniformly coating elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. Generally, it is widely used in leather, nameplate, stationery, electronics, automobile trim fixing, shoe industry, paper making, handicraft pasting and positioning, etc. It can also be used in stickers, stationery, office, etc. However, the existing adhesive tapes are not waterproof, and the cohesiveness is greatly reduced in high temperature or humid environments, which cannot meet the requirements for use. Contents of the invention [0003] The object of the present in...
