Description
Technical field
This utility model relates to platinum catalyst production technical field, particularly relates to a kind of platinum catalyst microcapsule.
Background technology
Along with the development of silicone rubber, for knitwear, cotton goods, the decorative pattern of Lycra elastic woven material and the silica gel of mark
Also getting more and more, the forming temperature of these product needed is the most relatively low, generally below 100 degree, is therefore accomplished by micro encapsulation
The wall material of platinum catalyst possesses low softening point temperature, when temperature rises to 100 degree, and platinum catalyst can flow out soon,
And select the high thermoplastic resin of toughness as epidermis to prevent microcapsule embrittlement in whipping process from needing.But, this
The platinum catalyst microcapsule catalytic efficiency of monolayer is the highest.
Summary of the invention
In order to solve above-mentioned technical problem, it is provided that the platinum platinum catalyst that a kind of catalytic efficiency is high, catalytic reaction is gentle
Microcapsule, this utility model offer techniques below scheme:
A kind of platinum catalyst microcapsule, described microcapsule center is liquid platinum catalyst, also includes that from-inner-to-outer depends on
The polyvinyl chloride layer of the secondary central outer surface being coated on, liquid platinum catalyst layer, polycaprolactone layer；Described polycaprolactone layer
Ring and ball softening point is less than the ring and ball softening point of polyvinyl chloride layer.
Platinum catalyst microcapsule of the present utility model is stirred with silica gel materials and starts to warm up, when temperature raises
During to the softening point of polycaprolactone layer, the liquid platinum catalyst of liquid platinum catalyst layer flows out, and starts to play catalytic action；
Following temperature continues to raise, and when being increased to the softening point of polrvinyl chloride, the platinum catalyst at center flows out.
Further, described liquid platinum catalyst layer is 1:3-4 with the volume ratio of liquid platinum catalyst.Liquid platinum
Silica gel molding is reacted with liquid platinum catalyst and is catalyzed by catalyst layer at twice, temperature when liquid platinum catalyst flows out
Spending the forming temperature closer to silica gel product, therefore, the liquid platinum catalyst amount at center requires more.
Further, the thickness of described polycaprolactone layer and polyvinyl chloride layer is than for 1:0.5-1, the thickness of polycaprolactone layer
More than or equal to polyvinyl chloride layer, being because polycaprolactone layer needs to consider its pliability as the outermost layer of microcapsule.
Further, described polycaprolactone layer is 1:1-2 with the thickness of liquid platinum catalyst layer.
The beneficial effects of the utility model are: be particularly well-suited to the silicone rubber of the add-on type of middle hot setting, silicones
Curing system；The catalyst system and catalyzing design of layering has the advantage that catalytic efficiency is high, catalytic reaction is gentle.
Accompanying drawing explanation
Fig. 1, primary structure schematic diagram of the present utility model.
In figure: 1, liquid platinum catalyst, 2, polyvinyl chloride layer, 3, liquid platinum catalyst layer, 4, polycaprolactone layer.
Detailed description of the invention
A kind of platinum catalyst microcapsule as shown in Figure 1, described microcapsule center is liquid platinum catalyst, also includes
The polyvinyl chloride layer 2 of the central outer surface that from-inner-to-outer is coated on successively, liquid platinum catalyst layer 3, polycaprolactone layer 4；Institute
State the ring and ball softening point ring and ball softening point less than polyvinyl chloride layer 2 of polycaprolactone layer 4.
Described liquid platinum catalyst layer 3 is 1:3 with the volume ratio of liquid platinum catalyst 1.Liquid platinum catalyst layer 3
Reacting silica gel molding at twice with liquid platinum catalyst 1 and be catalyzed, temperature when liquid platinum catalyst 1 flows out more connects
The forming temperature of nearly silica gel product, therefore, the liquid platinum catalyst amount at center requires more.
The thickness of described polycaprolactone layer 4 and polyvinyl chloride layer 2 ratio for 1:0.5, the thickness of polycaprolactone layer 4 more than or
Equal to polyvinyl chloride layer 2, being because polycaprolactone layer 4 needs to consider its pliability as the outermost layer of microcapsule.
Described polycaprolactone layer 4 is 1:1 with the thickness of liquid platinum catalyst layer 3.
Platinum catalyst microcapsule of the present utility model is stirred with silica gel materials and starts to warm up, when temperature raises
During to the softening point of polycaprolactone layer 4, the liquid platinum catalyst of liquid platinum catalyst layer 3 flows out, and starts to play catalysis and makees
With；Following temperature continues to raise, and when being increased to the softening point of polrvinyl chloride, the platinum catalyst at center flows out.
With above-mentioned foundation this utility model desirable embodiment for enlightenment, by above-mentioned description, relevant staff
Various change and amendment can be carried out completely in the range of without departing from this utility model technological thought.This practicality
The content that novel technical scope is not limited in description, it is necessary to determine that it is technical according to right
Scope.
