Abstract
The invention discloses a kind of two-component silane modified polyether sealing material and preparation method thereof, the two-component silane modified polyether sealing material includes silane modified polyether, plasticizer, extending fillers A, reinforced filling, toner, thixotropic agent, light stabilizer, hollow glass microballoon, crosslinking agent, coupling agent, extending fillers B, organotin catalysts, titanium catalyst etc..Two-component silane modified polyether sealing material of the present invention uses titanium catalyst partial alternative organotin, organic Theil indices low, it is possible to reduce the harm of organotin；Simple production process does not need high temperature dehydration, at low cost；The moisture of itself is utilized when solidification, glue-line outwardly and inwardly cures simultaneously, overcome one-component silane modified polyether seal glue temperature by moisture-curable, from outward appearance to inner essence, the slow defect of deep cure, solidification rate changes small with external environment, with good construction stability, production efficiency is greatly improved, the fields such as building, automobile, locomotive, electronic apparatus are can be widely applied to.
Description
Technical field
The present invention relates to polymeric material field, more particularly to a kind of two-component silane modified polyether sealing material and its
Preparation method.
Background technology
Traditional fluid sealant mainly has polysulfide, silicone, polyurethane, epoxy etc..Polysulfide sealant has stink, low-temperature setting
Slowly it, tends to age and harden, the shortcomings of durability is poor；Silicone sealant ageing-resistant performance is excellent, but its intensity is low, and resistance tocrocking is poor；
Although polyurethane sealant intensity is very high, containing free isocyanates, when solidification, easily forms bubble, loss of properties on aging,
And it is frequently necessary to cooperation primary coat and uses.Epoxy sealing glue high strength after curing, but it is very crisp, and internal stress is very big, ageing-resistant, resistance to Huang
Become poor performance.
With the development of economy, client is higher and higher to the performance requirement of fluid sealant, and personalization, the differentiation of demand
It is more and more obvious.20th century the seventies, Japanese Kaneka companies take the lead in developing silane modified polyether polymer, then develop
Go out silane modified polyether seal glue, since it is to the extensive cementability of base material, environment friendly, highly resistance deformational displacement ability, low
The advantages that pollution, receives market extensive concern.Currently, silane modified polyether seal glue occupied in Japanese architecture market it is leading
The market share of significant proportion is also occupied in status in states such as America and Europes.In China, research and development, the application of silane modified polyether seal glue
It is all still in the marketing stage with marketing.
Many patents all disclose silane modified polyether seal glue, are based on one-component, formula is mostly with organotin
Catalyst.In order to ensure the solidification rate of fluid sealant, organotin comparision contents are high, typically constitute from silane modified polyether 0.5%~
5%；Organotin has certain harm, European Union to limit use since 2010 health and environment.Although one-component product makes
With convenient, but while producing, needs high temperature dehydration, cooling, period long, of high cost；And solidification relies on the moisture in air, by outer
Boundary's environment influences significantly, and surface drying is slow when humidity is low, temperature is low, and surface drying is fast when humidity is high, temperature is high, cures from outward appearance to inner essence, deep layer
Slow curing, generally cured thickness is 4~6mm for 24 hours.
Invention content
Based on this, it is necessary to which in view of the above-mentioned problems, providing, a kind of organic Theil indices are low, production is simple, construction stability, deep layer
Two-component silane modified polyether sealing material of quick solidifying and preparation method thereof.
The purpose of the present invention is achieved by the following technical programs：
A kind of two-component silane modified polyether seal glue, including component A and B component, wherein according to the mass fraction, the A
Component includes：30~50 parts of silane modified polyether, 0~30 part of plasticizer, 40~60 parts of extending fillers A, reinforced filling 2~10
Part, 5~15 parts of toner, 0.05~3 part of thixotropic agent, 0.03~1 part of light stabilizer, 0~8 part of hollow glass microballoon, crosslinking agent 0~
3 parts, 0.05~3 part of coupling agent；The B component includes：5~40 parts of plasticizer, 10~55 parts of extending fillers B are organotin catalyzed
0.03~0.12 part of agent, 2~8 parts of titanium catalyst.
