Problems solved by technology

[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. However, when traditional sealants are used as water pipe interface sealing materials, due to the long-term humidity of the water pipe environment and the sewage components Rich in a large number of bacteria, long-term use is likely to cause bacterial growth in the connecting parts, affect the use effect, cause problems such as pipeline blockage or corrosion, and seriously affect the service life of the water pipe

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.

Description

technical field [0001] The invention relates to the technical field of sealing paste processing, in particular to a strong antibacterial sealing paste for water pipes. Background technique [0002] Sealant (sealant) is an adhesive used to fill the configuration gap to play a sealing role. It mainly introduces sealing materials that deform with the shape of the sealing surface, are not easy to flow, and have a certain degree of adhesion. They are divided into elastic sealants and liquid seals. There are three categories of padding and sealing putty. Sealants have the functions of anti-leakage, waterproof, anti-vibration, sound insulation, heat insulation, etc., and are widely used in the sealing of construction, transportation, electronic instruments and parts. Sealants are usually based on dry or non-drying viscous substances such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, and inert fillers such as talcum powder, clay, carbon black, ti...
