Description
Technical field
The present invention relates to a kind of synthetic methods of extraordinary silane-modified STP resin of high adhesiveness energy, belong to Chemical Engineering Technology neck
Domain.
Background technique
Silane modified polyether (STP) have health environment-friendly, pollution-free, adhesive property is good, good weatherability, can cover with paint, lacquer, colour wash, etc.；Extensively
For building, industry and assembling product field.
Although existing market silane modified polyether does not need silane coupling agent can reach good adhesive property, but such viscous
Connect the requirement that client is often not achieved in intensity.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide it is a kind of design it is reasonable, easy to operate
The synthetic method of the extraordinary silane-modified STP resin of high adhesiveness energy.
To achieve the above object, the technical solution adopted by the present invention is that: the step of synthetic method, is as follows:
Step 1: during 100 parts of isophorone diisocyanate is added in 500ml glass reaction kettle, meanwhile, starting
Stirring, revolving speed 200rpm；
Step 2: 200 parts of silane coupling agent KH540, normal-temperature reaction are added dropwise into reaction kettle, time for adding is 3h or so,
System keeps original temperature, that is, does not need heating and cooling；
Step 3: extraordinary silane reaction is completed after curing 1h；
Step 4: leaving 1~5 part of extraordinary silane in a kettle, 95~99 parts of STP is then added into reaction kettle
Resin, or so stirring half an hour, the i.e. extraordinary silane-modified STP resin of generation high adhesiveness energy, discharging.
Preferably, the isophorone diisocyanate and the ratio of silane coupling agent KH540 are about 1:2.
Preferably, temperature control is at 25-40 DEG C when stirring in the step 1.
Preferably, extraordinary silane is 2~3 parts in the step 4, STP resin is 96~99 parts.
The isophorone diisocyanate abbreviation IPDI is hydroxyl needed for the polyurethane binder of composite propellant
The curing agent of based prepolymers (i.e. glycol polypropylene).
The molecular structural formula of the silane coupling agent is general are as follows: Y-R-Si (OR) 3 (mono- organic functional base of Y, SiOR mono- in formula
Siloxy).Siloxy has reactivity to inorganic matter, and organic functional base has reactivity or compatibility to organic matter.Cause
This, when silane coupling agent between inorganic between organic interface, organic matrix-silane coupling agent-inorganic matrix knot can be formed
Close layer.
Typical silane coupling agent have A151 (vinyltriethoxysilane), A171 (vinyltrimethoxysilane),
A172 (vinyl three (beta-methoxy ethyoxyl) silane).Silane coupling agent KH540 of the invention is 3- aminopropyl trimethoxy.
The present invention makes the synthesis of extraordinary silane first, is then added to extraordinary silane in the system of resin STP, thus
Obtain modified STP resin.
After adopting the above structure, the invention has the following beneficial effects: a kind of extraordinary silane of high adhesiveness energy of the present invention changes
Property STP resin synthetic method, simple process is easy to operate, resulting modified STP resin have preferable adhesive property, and
Adhesion strength is high, is applicable to the fields such as building, industry and assembling product, in addition, the present invention has design rationally, cost of manufacture
Low advantage.
Specific embodiment
The synthetic method of present embodiment is:
