Description
Technical field
The invention belongs to fluid sealant technical field, is related to a kind of preparation method of modified silane polyethers glue.
Background technology
The full name of MS glue is modified silane polyethers glue, is new one to grow up after TR sealant, silicone adhesive, polyurethane adhesive
For building sealant.It is mainly used in the neck such as bonding, joint filling, seam, sealing and waterproof, reinforcement of architectural engineering and decorations
Domain；In recent years, as people constantly deepen to the understanding of MS glue advantage itself, in industrial circles such as refrigerator car, container, elevators
Application also constantly extending.
Traditional polyurethane sealant easily forms bubble due to containing free isocyanates, and when solidifying so that
It is restricted in many application fields.At present, domestic construction fluid sealant is instantly based on silicone adhesive, and by comparison, MS glue has
More, more prominent advantage：1. environmental-protecting performance is remarkable：Solvent-free addition, formaldehydeless toluene dimethylbenzene etc. pair in the production of MS glue
Human harmful substance's release, VOC content are minimum, environment-friendly and greens；2. widely bonding scope, more superpower bonding are strong
Degree, MS glue is applicable not only to most construction materials, more to the engineering plastics such as acrylic, ABS, lucite and concrete etc.
Porous materials have good cohesive force, have more, wider application than silicone adhesive, by experiment：The superpower structure glue of grand nation
Every square decimeter of 300KG/ can be born, adhesion strength is very good；3. oiliness molecule thing pollution building material surface and seam will not be escaped,
Permanent to keep the attractive in appearance of building, silicone adhesive can separate out small molecule thing, and together with rainwater and dust, difficulty is formed in facade
With the stains of removal；4. pair most of paint and coating mutually compatibility, colloid surface can paint covering with paint, and silicone adhesive can be because of surface tension
Contraction cause covering with paint to be unable to maintain that；5. the harmony of overall performance is also best.To sum up, conventional silicone sealant due to
Tearing strength is low, and covering with paint property is poor, easily pollutes building materials, is restricted its application.
Silane modified polyether seal glue (abbreviation MS fluid sealants) be it is a kind of using silyl-terminated polyether (using polyethers as main chain, two
End siloxane blocking) based on polymer prepare high-performance environment-friendly fluid sealant, it has had polyurethane sealant and silicone concurrently
The advantages of fluid sealant, the deficiency of respective performance is overcome, there is excellent mechanical strength, covering with paint property, resistance to soiling, and do not have in product
There are isocyanates and organic solvent, be the main direction of development of domestic and international novel elastic fluid sealant.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of preparation method of modified silane polyethers glue,
The adhesion strength of obtained modified silane polyethers glue is high, and elongation and tensile strength are good.
To use following technical scheme up to this purpose, the present invention：
The preparation method of the modified silane polyethers glue of the present invention, the preparation method comprise the following steps：
1) by weight, 10~20 parts of plasticizer, 60~70 parts of powder, 1~2 part of silane coupler are placed in
It is stirred in reactor, vacuum drying；
2) by weight, in the compound that step 1) obtains add 0.1~0.5 part antioxidant, 0.1~0.5 part
Light stabilizer, 1~3 part of silane coupler, normal heating, cooling processing；
3) 10~30 parts of modified silane polyether resin by weight, is added in the compound that step 2) obtains
30000T, 1~5 part of gas-phase silica, stir under vacuum condition；
4) by weight, added in the compound that step 3) obtains surplus silane coupler, 0.1~0.3 part
Catalyst, the modified silane polyethers glue is obtained after stirring, pressurize under vacuum condition.
Heating can be closed after temperature of charge reaches 80 DEG C in step 1), and observes temperature and does not exceed 80 DEG C to prevent later stage drop
The warm time is too long, and mixing speed can be suitably reduced after material stirring is uniform, is easy to post drop.Wherein, the vacuum for-
0.1~0MPa, for example, vacuum be -0.1MPa, -0.08MPa, -0.06MPa, -0.05MPa, -0.04MPa, -0.03MPa, -
0.02MPa、-0.01MPa；The temperature of drying be 60~80 DEG C, such as drying temperature for 60 DEG C, 61 DEG C, 62 DEG C, 63 DEG C, 64

℃、80℃；The time of drying is 15~20min, for example, the time of drying be 15min, 16min, 17min, 18min, 19min,
20min, the main purpose of this step is material dispersion, degassing dehydration.
In step 2), the temperature of the heating is 65~70 DEG C, for example, the temperature of heating is 65 DEG C, 66 DEG C, 67 DEG C, 68
℃、69℃、70℃；The cooling processing is to be cooled to 50 DEG C after compound is maintained into 50~70min under the conditions of 65~70 DEG C.
While cooling, chemistry is removed water, and the moisture in compound is further reduced, whole process normal pressure.
, can after addition matrix resin modified silane polyether resin 30000T and thixotropic agent gas-phase silica in step 3)
To reduce the temperature of system, faster mixing speed is advantageous to gas silicon and disperseed, but easily elevates the temperature, and visual gas silicon disperses feelings
Condition suitably reduces stir speed (S.S.) and shortens the time, and the whipping temp of this step is at 40 DEG C or so.Modified silane polyether resin
30000T is more sensitive to liquid to steam ratio due to being blocked using both ends trimethyl, so should not be in the big step 1) of temperature high-moisture
Add, be adapted to add in this step.
In step 4), time for being stirred under the vacuum condition is 20~40min, for example, the time of stirring be 20min,
25min、30min、35min、40min；The vacuum of vacuum pressurize is -0.05~0MPa, for example, vacuum be -0.05MPa, -
0.04MPa、-0.03MPa、-0.02MPa、-0.01MPa.The temperature control of this step is below 40 DEG C, in order to avoid become after ingress of air
Matter.
The preparation method of the modified silane polyethers glue of the present invention, by controlling the order of addition of each raw material, drying and processing, stirring
The control of temperature, mixing time and vacuum is mixed, the factor for influenceing modified silane polyethers glue Storage period and stability is dropped to most
