[0003] Sealant is a kind of sealant. It is mainly made of liquid polysulfide rubber as the base material. It is a polysulfide sealant that can be self-vulcanized and cross-linked at room temperature. It has good adhesion to metals and concrete and other materials. It maintains good airtightness and water resistance under , vibration and temperature changes, and is oil-resistant, solvent-resistant, and durable. H...

Abstract

The invention relates to the technical field of sealing paste processing, and provides a highly antibacterial sealing paste for a water pipe. The highly antibacterial sealing paste for the water pipeis prepared from raw materials with the following parts by weight: 80-100 parts of chloroprene rubber adhesive cement, 10-15 parts of butadiene styrene rubber, 4-6 parts of polytetrafluoroethylene, 2-4 parts of sepiolite fibers, 1.4-1.6 parts of methylparaben, 4-6 parts of glutaraldehyde, 2-3 parts of nano-silica, 1-3 parts of diatomite, 0.6-1.2 parts of basic cupric carbonate, 0.6-0.8 part of dicumyl peroxide, 0.4-0.6 part of a dispersant, 0.5-0.7 part of an antioxidant, and 0.2-0.4 part of a thickener. The highly antibacterial sealing paste for the water pipe provided by the invention has the advantages that defects in the prior art are overcome; and under the premise that the anti-oxidization and anti-corrosion capabilities of the sealant are effectively improved, the bacteria growth can be inhibited, so that the pipe is less likely to be damaged by microorganisms, the product durability is improved, and the service life of the pipe is prolonged.
