Water-proof sealing adhesive tape and its preparation method

Abstract

The invention provides a waterproof sealing adhesive tape and the preparation method thereof, which relates to the technology field of the waterproof sealing adhesive tape and the preparation thereof. The waterproof sealing adhesive tape is composed of a waterproof sealing layer and two pieces of adhesive-proof oil paper attached to the both sides of the waterproof sealing layer, the waterproof sealing layer and the two pieces of adhesive-proof oil paper are produced through calendering and compounding, the waterproof sealing layer comprises the following components and contents (by weight): 100 parts of butyl rubber, 60 to 80 parts of silicon dioxide, 8 to 25 parts of polyolefine, and 70 to 120 parts of tackifier. The waterproof sealing adhesive tape has the raw materials which are easy to be acquired, low in cost and suitable for the industrialized production, the performance index thereof can fully exceed the technical level of the similar domestic products, the product has high tensile strength and peeling strength and good high and low temperature resistant performances, and can still play the role of waterproof sealing under the high temperature of 90 DEG C and the low temperature of minus 40 DEG C and under the pressure of 0.08 MPA.

Description

A kind of waterproof sealing tape and preparation method thereof technical field The invention relates to the technical field of waterproof sealing tape and its preparation, in particular to a waterproof sealing tape with high tensile strength and peeling strength, excellent high and low temperature resistance and a preparation method thereof. Background technique Heat-shrinkable materials and waterproof sealing tape are usually used to insulate and waterproof the joints of various wires and cables. When performing insulation and waterproof sealing, the waterproof sealing tape is first wrapped around the joints of the wires and cables, and then the outside is covered with a heat-shrinkable tube, heated and heat-shrinked. The tube makes it shrink, and the heat-shrinkable tube is bonded to the wire and cable through the waterproof sealing tape, which plays the role of insulation and waterproof sealing of the joint of the wire and cable. At present, this kind of waterproof se...
