Abstract

The invention discloses a preparation technology of a cotton paper double-sided adhesive tape. The preparation technology comprises the following steps: cutting modified cotton paper into a required size to serve as a base material, coating the surfaces of two sides of the base material of the adhesive tape with an adhesive to form a double-sided adhesive layer, adhering release paper to the adhesive layer to form a release paper layer, and rolling the release paper layer to obtain the cotton paper double-sided adhesive tape. The modified cotton paper is adopted as the base material of the double-sided adhesive tape, so the defect of poor mechanical properties of traditional cotton paper can be overcome; the modified cotton paper has high hydrophobicity and good biodegradability, so the effects of high mechanical properties and high hydrophobicity are achieved on the basis of meeting the environmental protection requirement; the soybean protein adhesive adopted in the invention has a high adhesive property, and can be stably attached to the surface of the modified cotton paper to increase the adhesive property; and the obtained cotton paper double-sided adhesive tape has the advantages of environmental friendliness, good mechanical properties, strong hydrophobic property and high adhesive property, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of double-sided adhesive tapes, and in particular relates to a preparation process of tissue paper double-sided adhesive tapes. Background technique [0002] Adhesive tape is one of the commonly used fixing and masking tools in daily life and work. According to its function, it can be divided into high temperature tape, double-sided tape, insulating tape, special tape, pressure sensitive tape, die-cutting tape, etc., which are applicable according to different functions. In different places and fields, double-sided tape is one of the most commonly used tapes. Double-sided tape is based on paper, cloth, and plastic film, and then evenly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive. The roll-shaped adhesive tape made on the above-mentioned substrate is composed of three parts: substrate, adhesive, release paper (film) or silicone oil paper. In order to meet ...
