Biodegradable double-sided adhesive tape

Abstract

The invention discloses a biodegradable double-sided adhesive tape. The double-sided adhesive tape comprises a base material layer, an adhesive layer and release paper, wherein the adhesive layer is positioned between the base material layer and the release paper, the release paper adopts glassine paper coated with silicone oil, the base material layer is a non-toxic and pollution-free mixed material layer, and the adhesive is a biodegradable quaternary random co-polyester adhesive. The invention discloses the biodegradable double-sided adhesive tape. The double-sided adhesive tape has the advantages of reasonable material selection, environmental friendliness and safety, can not only meet the requirements of initial adherence, sustained adherence and stripping strength, but also realize excellent biodegradable property, and further has great application prospects in the aspects of stickers, stationery, office supplies and the like.

Description

technical field [0001] The invention relates to a double-sided adhesive tape, in particular to a biodegradable double-sided adhesive tape, which belongs to the technical field of adhesive tapes. Background technique [0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth, and plastic film as the base material, and then uniformly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. , adhesive, and release paper are composed of three parts. Double-sided tape is widely used in leather, stickers, stationery, office, electronics, car trim fixing, shoe industry, handicraft pasting and positioning, etc. [0003] In today's society, with the enhancement of human's awareness of environmental protection, the research and development of environmentally friendly double-sided tape has gradually received great attention. At present, double-sided adhesive tapes used in sticke...

AI Technical Summary

Problems solved by technology

At present, double-sided adhesive tapes used in stickers, stationery, office and other aspects have relatively serious environmental protection problems. Due to the large demand for double-sided adhesive tapes in these industries, many manufacturers use low-priced, The preparation of double-sided adhesive tape from toxic and easily residual polluting chemical raw materials has caused great harm to the environment and human health; as the core part of double-sided adhesive tape, the adhesive has always been the focus of research and development. At present, an environmentally friendly bio- Degradable adhesives are favored because they can degrade into carbon dioxide and water under the action of microorganisms

At this stage, the domestic development of biodegradable double-sided adhesive tape started relatively late, and there are few developments, and it is rare to see more mature products launched in the market.
