Problems solved by technology

[0003] Due to the need for water stop, the traditional rubber water stop is forbidden to nail or perforate during the installation process, which makes it difficult to locate the water stop. It is also prone to displacement, deformation, curling and other quality problems during concrete pouring, resulting in water stop and sealing effect Greatly reduced
Moreover, the traditional rubber waterstop still needs to be improved in terms of tear resistance, low temperature resistance, and long-term corrosion resistance.

Abstract

The invention provides a rubber waterstop which comprises a horizontal main body of the rubber waterstop, a plurality of sets of vertical auxiliary bodies are arranged on the horizontal main body in a central symmetry mode, a central through hole is formed in the midpoint position of the horizontal main body, and a left end through hole and a right end through hole are formed in the extending tail end position of the horizontal main body. The vertical auxiliary bodies are symmetrically arranged on the two sides of the center through hole. The rubber waterstop is of an integrally formed structure and is prepared from the following raw materials in parts by weight: 100-120 parts of ethylene propylene diene monomer, 10-20 parts of low phenyl silicone rubber, 15-25 parts of bentonite, 15-20 parts of water-absorbent resin, 5-8 parts of a peroxide crosslinking agent, 15-20 parts of a reinforcing agent, 3-5 parts of zinc oxide, 5-10 parts of a softening agent, 1-2 parts of a vulcanizing agent, 1-2 parts of an anti-aging agent, 1-2 parts of an accelerant, 1-2 parts of a mildew preventive and 1-2 parts of a plasticizer. The rubber waterstop does not shift, deform or curl; due to the material design, the material has good tear resistance, low-temperature resistance, plasticity and repeated soaking expansibility.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of a rubber waterstop and the rubber waterstop. Background technique [0002] The rubber waterstop is made of a material that not only has the characteristics of rubber products, but also has the function of self-expanding when encountering water to stop water. Widely used in civil air defense, subway, tunnel, sewage treatment project, swimming pool, etc. and other concrete engineering construction joints, expansion joints, cracks. The rubber waterstop uses natural rubber and various synthetic rubber as the main raw materials, mixed with various additives and fillers, and is molded, kneaded, and pressed. [0003] Due to the need for water stop, the traditional rubber water stop is forbidden to nail or perforate during the installation process, resulting in difficulty in positioning the water stop, and it is also prone to displacement, d...
