Description
Technical field
The present invention relates to a kind of preparation method, in particular it relates to a kind of preparation method of paste alcohol type organosilicon sealant.
Background technology
It still can be corrosive present fluid sealant to some materials, while have certain harm to human body, not environmentally,
Shelf-life is short, and application surface is very little.
The content of the invention
For in the prior art the defects of, the technical problem to be solved in the present invention is to provide a kind of paste alcohol type organosilicon is close
The preparation method of sealing, its is more environmentally friendly, and the shelf-life is longer, does not have corrosivity to base material, and application surface is more extensive.
According to an aspect of the present invention, there is provided a kind of preparation method of paste alcohol type organosilicon sealant, it include with
Lower step：
Step 1, alkoxy end-capped dimethyl silicone polymer, plasticizer, crosslinking agent, coupling agent are mixed；
Step 2, after being well mixed, filler is added, is mixed under -0.08~-0.1MPa vacuum；
Step 3, after the completion of mixing, catalyst is added, then mixed with planetary stirrer.
Preferably, for the step 1 into step 3, the ratio of each raw material is alkoxy end-capped dimethyl silicone polymer：
36.2%th, plasticizer：36.1%th, crosslinking agent：7.2%th, coupling agent：1.8%th, filler：18%th, catalyst：0.7%.
Preferably, the plasticizer is trimethoxy dimethyl silicone polymer.
Preferably, the crosslinking agent is MTMS.
Preferably, the coupling agent is aminopropyl trimethoxysilane.
Preferably, the catalyst is dibutyl tin laurate.
Preferably, the filler is fume colloidal silica.
Compared with prior art, the present invention has following beneficial effect：The present invention is more environmentally friendly, and the shelf-life is longer, to base
Material does not have corrosivity, and application surface is more extensive.
Embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
The preparation method of paste alcohol type organosilicon sealant of the present invention comprises the following steps：
Step 1, alkoxy end-capped dimethyl silicone polymer, plasticizer, crosslinking agent, coupling agent are mixed；
Step 2, after being well mixed, filler is added, is mixed under -0.08~-0.1MPa vacuum；
Step 3, after the completion of mixing, catalyst is added, then mixed with planetary stirrer.
For step 1 into step 3, the ratio of each raw material is alkoxy end-capped dimethyl silicone polymer：36.2%th, it is plasticized
Agent：36.1%th, crosslinking agent：7.2%th, coupling agent：1.8%th, filler：18%th, catalyst：0.7%.
Plasticizer is trimethoxy dimethyl silicone polymer, can so improve fixedness.
Crosslinking agent is MTMS, can so improve humidity resistance.
Coupling agent is aminopropyl trimethoxysilane, and hydrolysis and cross-linking reaction so easily occurs.
Catalyst is dibutyl tin laurate, so with excellent lubricity, transparent, weatherability.
Filler is fume colloidal silica, so can be with high temperature resistant.
In summary, the present invention is more environmentally friendly, and the shelf-life is longer, does not have corrosivity to base material, and application surface is more extensive.
The specific embodiment of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring the substantive content of the present invention.
