Abstract

The invention provides a preparation method of a novel high-toughness shield strip and an application method of the novel high-toughness shield strip. The method comprises the following steps: step 1, collecting ingredients, such as chloroprene rubber, natural rubber, silicone rubber, ethylene propylene diene monomer, acrylate rubber, polyurethane rubber and water-based resin; 2, the collected rubber is weighed and rechecked, and materials are prevented from being mismatched; step 3, mixing the collected rubber, dispersing and uniformly mixing; step 4, grinding the uniformly mixed rubber to enable the rubber material to have better flowability; and step 5, carrying out compression molding on rubber with good fluidity. The shield strip is suitable for waterproof sealing of joints of spliced underground engineering pipelines. According to the preparation method and the application method of the novel high-toughness shield strip, the problems that better high toughness and abrasion resistance cannot be achieved conveniently, and meanwhile the service life cannot be prolonged conveniently are solved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling bars, in particular to a preparation method of a novel high-toughness shield tunneling strip and an application method thereof. Background technique [0002] The shield bar, also called the shield segment, is a rubber gasket that expands when exposed to water, so as to achieve a water-tight sealing effect. In tunnel engineering, the hydraulic pressure analysis is usually carried out through the force principle of the shield bar to achieve the sealing effect. , so that it is not easy to open, to play the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, fixation, etc., there are rubber, paper, metal, plastic and other materials, but the shield bar is made of rubber However, there are still some deficiencies when using shield bars, such as: [0003] The notification number is CN102380964B, which provides a method for preparing a sealing strip. First, extru...
