Abstract

The invention discloses a flame retardant environment-friendly polysulfide sealant and a production method of the sealant. The sealant consists of a sealant component A and a sealant component B, wherein the sealant component A comprises the following components in parts by weight: 100-120 parts of polysulfide glue, 20-25 parts of butyl benzyl phthalate, 2-3 parts of nanosilver, 20-30 parts of nano calcium carbonate, 5-7 parts of aluminum hydroxide, 5-10 parts of nano titanium dioxide, 5-7 parts of epoxy resin, 20-28 parts of carbon black and 0.5-0.9 part of a coupling agent; the sealant component B comprises the following components in parts by weight: 50-60 parts of manganese dioxide, 20-30 parts of butyl benzyl phthalate and 1-2 parts of diphenylguanidine. According to the sealant, the nanosilver is added into the polysulfide sealant as an antifungal agent, aluminum hydroxide as a flame retardant and nano calcium carbonate, nano titanium dioxide and carbon black as reinforcing agents, so that the sealant satisfies the flame retardance requirement and the environment-friendly requirement of European Union ROHS (Restriction Of Hazardous Substances).

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a two-component flame-retardant and environment-friendly polysulfide sealant for construction and a production method thereof. Background technique [0002] Polysulfide sealant is an elastic sealing material with liquid polysulfide rubber as the main material. It has excellent adhesive performance, good air tightness, water tightness and low temperature flexibility, excellent aging resistance, oil resistance and solvent resistance. Widely used in construction, transportation, refrigeration, electrical instrumentation and other industries. [0003] Modern construction and chemical industry have higher and higher requirements for sealants, especially the requirements for flame retardancy and environmental protection. It is required that the flame retardancy effect is good, the materials are environmentally friendly and harmless to the human body. Because the ...
