Abstract
A water-proof dual-component polysulfide sealing agent is prepared from components A and B through proportional mixing in ratio of 100:(8-12). The component A contains liquid-state polysulfide rubber, plasticizer, activated light and heavy calcium carbonate, white carbon black and coupling agent epoxy silane. The component B contains MnO2, dibutyl ester, semi-reinforced carbon black and sulfurizing promoter. They are prepared through mixing, stirring, heating, compression, vacuum, grinding, inspecting and loading in bucket.
Description
Invention field
The present invention relates to bi-component polysulfide waterproof sealing agent and preparation method thereof.
Technical field
Waterproof sealing agent is widely used in fields such as water conservancy, building, people's air defense, subway, tunnel, highway, environmental engineering, water works.Because waterproof sealing agent is under the condition of long-term immersion, and the sealing agent performance has been proposed harsh requirement.For example, in process water, easily produce anaerobic digestion; The flow velocity of water is very fast in water channel and canal; Easily produce abrasion and chemical erosion at water treating equipment in the tank with drinking; Require the sealing material curing speed to want fast in the coastal engineering; Produce the abrasion and the chemical erosion of sand, organism, oils in the sewage disposal, need the sealing material of strong anaerobic digestion, high temperature resistant, acidproof, anti-methane gas and carbon dioxide of opposing.Therefore, under the envrionment conditions of soaking for a long time, sealing material will be subjected to physics, chemistry, biochemical erosion, requires waterproof sealing agent must have the excellent comprehensive performance.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of bi-component polysulfide waterproof sealing agent with excellent comprehensive performance.
