Abstract

The invention discloses waterproof adhesive tape and relates to the technical field of adhesive tape. The adhesive tape is formed by combining a PE substrate with an adhesive layer. The adhesive layeris prepared from sodium alginate / a hybrid-silica-modified acrylic emulsion, a silane coupling agent, nano-calcium carbonate, butyl rubber powder, sodium tripolyphosphate, diethanolamide cocoate, hydroxypropyl starch sodium phosphate and deionized water.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a waterproof adhesive tape. Background technique [0002] With the advancement of industrial technology, the use of adhesive tape has become increasingly popular in many fields such as daily life or engineering construction operations. With the development of the economy, environmental protection issues have become more and more popular. Polyethylene is non-polluting and toxic, and can be recycled Reuse, using polyethylene as a base material to prepare environmentally friendly adhesive tape can have a wide range of applications. [0003] In the actual application of the adhesive tape, it is often applied in an environment in contact with water. Due to the erosion of water, it is easy to cause degumming, which makes the adhesive tape unusable and brings a lot of trouble and inconvenience. Contents of the invention [0004] The object of the present invention is to provid...
