A polymer self-adhesive tape, its production method and its application

Abstract

The invention relates to a polymer self-adhesive tape, a production method and its application. In parts by weight, its raw material formula is as follows: 25-50 parts of styrene-isoprene-styrene block copolymer; 10~30 parts of agent; 30~60 parts of first tackifying resin; 3~10 parts of nano filler; 10~20 parts of second tackifying resin; 0.02~0.05 parts of ultraviolet absorber; The first tackifying resin is a mixture of one or two of carbon five hydrogenated petroleum resins and terpene resins; the second tackifying resin is one or more of petroleum resins, terpene resins and rosin resins A mixture of several components. By adding components such as first tackifying resin, second tackifying resin, plasticizer and nano filler to styrene-isoprene-styrene block copolymer, the adhesive tape prepared in this way is compatible with concrete, aluminum alloy and Materials such as plastic steel have excellent bonding properties, and are also extremely soft. It is easy to achieve obedience and compactness at the irregular-shaped parts of the nodes, and can adapt to various structural deformations.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a self-adhesive tape, in particular to a polymer self-adhesive tape, a production method and an application thereof. Background technique [0002] Building leakage has always been one of the most complained problems in construction projects. Roof leakage, toilet leakage, kitchen, exterior wall leakage, and basement leakage are regarded as architectural "cancers". Many newly built projects have serious leakage in the year of completion. One of the important reasons leading to building leakage: there must be waterproof defects in the joint parts sealed only by ordinary waterproof paint! The waterproof coating with poor elongation is cracked and leaked due to objective factors such as thermal expansion and contraction, uneven settlement, and different linear expansion coefficients of different materials at the joints of the yin and yang angles, pipe roots, and supports.
