Problems solved by technology

Ordinary rubber waterstops cannot meet the performance requirements of high-speed railways
In addition, the underground conditions in some constructions are complex, which has a strong corrosion effect on the rubber waterstop, which greatly reduces the performance of the rubber waterstop in this environment, greatly affects its sealing and water-stop performance, and causes the building structure to be damaged. Water leakage, deep water, resulting in seal failure

Abstract

The invention discloses a high-tensile-strength water stop and a preparation method thereof. The water stop comprises the following components by weight: 40 to 80 parts of composite reinforcing agent, 20 to 30 parts of vulcanizing agent, 5 to 10 parts of vulcanization accelerator, 30 to 50 parts of EPDM (ethylene propylene diene monomer) rubber, 10 to 20 parts of neoprene, 10 to 15 parts of plasticizer, 8 to 12 parts of styrene-butadiene rubber, 2 to 8 parts of light magnesium oxide, 1 to 5 parts of tribasic lead phosphate, 10 to 20 parts of chlorinated paraffin, 5 to 10 parts of reinforcing filler, 2 to 8 parts of crosslinking agent, 2 to 4 parts of reactive diluent, 3 to 5 parts of toughening agent, 10 to 15 parts of high abrasion furnace black, 2 to 7 parts of anti-aging agent, 1 to 3 parts of plasticizer, 5 to 8 parts of anti-settling agent, and 10 to 15 parts of compounding agent. The water stop is suitable for use in infrastructure engineering, underground facilities, tunnels, sewage treatment plants, water conservancy, subways and other projects, and has the characteristics of high tensile strength, aging resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a waterstop with high tensile strength and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, traffic congestion, environmental pollution and energy crisis have become urgent problems to be solved. Underground transportation such as subways can avoid congestion on urban roads and make full use of underground space. It also has the advantages of speed and convenience. It has become the first choice for large and medium-sized cities to solve urban traffic congestion. In the construction process of some underground projects, due to the impossibility of continuous pouring, or the thermal expansion and contraction of concrete members caused by the deformation of the foundation and the change of temperature, it is necessary to leave construction joints, settlement joints, and deformation joints. Need to install water stop belt to prevent water seepage. At the same time, the constructi...
