Problems solved by technology

[0003] Although ordinary BOPP tapes on the market have reliable adhesion during use, they generally have the following defects: poor peelability, when the carton needs to be opened and the tape is torn off, it is easy to cause damage to the surface of the carton to varying degrees, or in the The residual adhesive on the surface of the carton, especially when the friction coefficient of the carton surface is large or the strength of the carton is low, the degree of damage is more obvious, resulting in most packaging cartons being unusable after opening, and it is also not conducive to the separate recycling and recycling of cartons and tapes.

Abstract

The invention relates to the technical field of new materials, and particularly discloses glue, a preparation method thereof and an adhesive tape. The glue is prepared from the following raw materials in parts by weight: 4000-5000 parts of water A, 25-35 parts of an emulsifier, 2.5-4.5 parts of a plasticizer, 90-110 parts of acrylic acid, 6000-6800 parts of butyl acetate, 30-40 parts of an initiator, 7-12 parts of a wetting agent, 15-25 parts of hydroxyethyl cellulose, 3-7 parts of organic bentonite and 8-12 parts of aliphatic mineral oil. The plasticizer is a mixture of an epoxy fatty acid methyl ester plasticizer and triacyltributyl citrate in a mass ratio of 1: (0.5-0.8). The preparation method comprises the following steps of: preparing a pre-dripping material; and preparing glue. The invention further discloses an adhesive tape which comprises an adhesive tape film, and the surface of one side of the adhesive tape film is coated with the glue. The adhesive tape has the characteristics that the peelable performance of the adhesive tape is improved, and damage to cartons is reduced.

Description

technical field [0001] This application relates to the technical field of new materials, more specifically, it relates to a kind of glue and its preparation method and adhesive tape. Background technique [0002] BOPP tape is a sealing tape obtained by using BOPP biaxially oriented polypropylene film as the base material, and applying pressure-sensitive adhesive emulsion evenly after heating to form an adhesive layer. BOPP tape has the advantages of high tensile strength, light weight, low cost, and non-toxic. As a packaging material, it is widely used in sealing packaging of cardboard boxes, fixing objects, bundling and sealing, etc. [0003] Although ordinary BOPP tapes on the market have reliable adhesion during use, they generally have the following defects: poor peelability, when the carton needs to be opened and the tape is torn off, it is easy to cause damage to the surface of the carton to varying degrees, or in the The residual adhesive on the surface of the carton...
