Description
Technical field
The present invention relates to sealant technical field, specially a kind of MS sealant processing technology.
Background technique
Silane modified polyether seal glue (MS sealant) is also known as organosilicon modified polyether sealant and silyl-terminated polyether is close
Sealing, it is that one kind is prepared using silyl-terminated polyether (using polyethers as main chain, both ends siloxane blocking) for basic polymer
High-performance environment-friendly sealant, the advantages of having silicone sealant and polyurethane sealant concurrently because of it and strong point are shown excellent resistance to
Hou Xing, durability, high anti-deformational displacement ability, good caking property, covering with paint property, the friendly property of environment, low staining, low-viscosity
The advantages that with excellent workability, increasingly obtains the concern of domestic construction industry, and in industrial circle such as automobile manufacture, track
The fields such as traffic, Production Container, device fabrication, electric are also just more and more being promoted the use.
Current MS sealant has the disadvantages that
1. unhealthy environmental protection, traditional sealant (silicone adhesive) can release formaldehyde, (volatility has VOC because containing solvent
Machine object) etc. endanger the physical and mental health of people.
2. easy to pollute, silicone oil can be precipitated in traditional silicone sealant, make its adhere to polluter, in particular for stone material,
When the porous material such as concrete, surrounding can be generated and be difficult to the pollution that removes, be cause outside vertical surface of building to pollute main
One of source substantially reduces the aesthetics and image value of building.
3. caking property is poor, in silicone adhesive, polyurethane adhesive and M sealant, silicone adhesive force is relatively weak, polyurethane
Adhesive force is strong, but needs that primary coat is cooperated to use, and MS sealant has excellent adhesive property, can adapt to most buildings
Substrate is bonded without primary coat.
4. covering with paint property problem, traditional silicone sealant are not available paint finishing, generally require through the tune to colloid
Color, to keep the solid colour with exterior coating, production process is time-consuming bothersome, and color be difficult to ensure it is identical, simultaneously
Cost is also difficult to control.
5. stress retentivity is poor, construction substrate can be shunk with the pushing away Tong of time, and seam is caused to have slowly
Widened tendency can bear biggish mechanical function in conventional seals gluing junction, and sealant rupture occurs and adhesive surface is damaged
The problems such as.

Experiment case study
Certain production of construction materials enterprise is respectively labeled as No. 1 sample, No. 2 using MS sealant made from 1-5 of the embodiment of the present invention
Sample, No. 3 samples, No. 4 samples and No. 5 samples, while the sealant of same type available on the market is chosen labeled as No. 6 samples
Product, then to this, sample carries out caking property and stress test respectively in 6, chooses six groups of materials and size building all the same respectively
Then plate coats corresponding sample glue on every group of building board, after standing 10-15min, testing crew can be by every group
Building board is pullled, and to judge the stress and quasi-viscous effect of each sample sealant, during pullling, testing crew can be remembered
It records the greatest limit between every group of building board and pulls distance, while the residual condition of sealant on building board is observed
And record.
By table Fig. 3 it is found that the greatest limit of corresponding No. 1 sample of embodiment 1 pulls distance than the maximum pole of other samples
It is big that limit pulls distance, while building board face seal glue residua object is handed over less, and No. 2 samples, No. 3 obtained by embodiment 2-5
The greatest limit of sample, No. 4 samples and No. 5 samples pulls distance than No. 6 samples of the sealant of same type available on the market
Distance it is big, and building board sealing glue residua is less, and therefore, the present invention can be achieved by the molecular configuration of MS glue to determine it
Original weatherability, good elasticity can still be kept by being chronically exposed to open air, and colloid itself will not generate bubble, will not produce
Raw cracking, adhesion strength have good thixotropy and extrudability, it is more to adapt to outdoor, indoor, moist and low temperature etc. persistently such as one
Kind operating environment, MS sealant are free of formaldehyde and isocyanates, and solvent-free, nontoxic, tasteless and VOC release is marked well below country
Standard is most environmentally friendly building adhesive product, and MS sealant will not pollute outside vertical surface of building, while MS sealant can be straight
It connects and carries out covering with paint operation in colloid surface, it is not compatible with most coating, while avoiding puzzlement, and perfect realization exterior wall
The unification of color, to keep the beauty of building body, in addition, MS sealant does not generate pollution to coating surface, coating may be used also
To extend the service life of sealant, overall cost is more reduced, MS sealant has both stress and elasticity simultaneously, even if long-term place
In tensional state, under the action of stress mitigates, construction substrate can be eliminated to the maximum extent and shrinks bring influence.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those
Element, but also including other elements that are not explicitly listed, or further include for this process, method, article or equipment
