Description
Technical field
The utility model relates to a kind of device for the preparation of ultralight polymer hollow microsphere, belongs to processing of high molecular material equipment technical field.
Background technology
Ultralight polymer hollow microsphere refers to the microballoon blowing agent (namely foaming heat expandable microspheres) expanded, microballoon blowing agent (i.e. thermo-expandable microspheres) is known in the prior art, and has a detailed description in US3615972, EP486080, EP566367, EP1067151, ZL201210241564.5, ZL201210241578.7, the files such as 201280073857.5 and 2012100109302.3.At present, the form of microballoon blowing agent has dry powder and wet pulp two kinds.In this microballoon housing, blowing agent is wrapped in thermoplastic housing with capsule form.Once heating, blowing agent evaporation produces internal pressure, and simultaneously along with housing softens, cause microballoon effectively to foam, general diameter increases about 2 to 5 times.
Thermoplastic microspheres that is unexpanded and that expanded can be applied in various field.Such as, the dry microballoon expanded can be applied in emulsion as sensitizer, also can be filled in solvent-based paints, coating and various thermosetting plastics (as artificial marble, body solder, engineered wood) as light filling thing.Wet expandable microspheres, usually stores with aqueous suspension slurry form, can be applied in many products, as water paint, thermal printing paper, porous ceramics and emulsion etc.
Transport expandable microspheres and often need very large space, exactly because also this reason expandable microspheres end user usually purchases unexpanded expandable microspheres, Expansion on site or directly unexpanded expandable microspheres is joined in production stage for the preparation of final products.
Due to the high temperature that expands completely needed for heat-swellable microballoon thus the problem that can cause causing the thermoplastic housing of microballoon mutually to bond because expanding and lump.This needs to provide a kind of method and apparatus for the preparation of expansion thermo-expandable microspheres, wherein degrees of expansion can be controlled, likely to provide the expandable microspheres of different densities, simultaneously they are simply and only need less space, relatively cheap, and be easy to be used by end user, and used on the spot due to expandable microspheres, thus save transport space and cost.
Many patents are all mentioned expanded thermoplastic expandable microspheres method and apparatus.As US Patent No. 5484815 and US7192989 have set forth the method and apparatus that applicable expandable microspheres dry powder expands.And US Patent No. 4513106 proposes the method and the device that are applicable to microsphere slurries expansion, its action principle in expended microsphere slurry, introduces steam and produces enough pressure heating microballoons, it is made to have certain expansion at least, then the microballoon of microdilatancy leaves pressure span with the speed of at least 1m/s, because pressure reduces, microballoon is expanded further.Although the method that US4513106 patent proposes expansion microballoon in slurry form can solve direct expansion microballoon dry powder and cause the phenomenon that dust is around many, the microsphere slurries expansion process described in US4513106 patent is to be further improved in addition.EP0348372 discloses a kind of technique preparing expansion thermoplastic microsphere, and wherein expanding betides on conveyer belt.Described process operation is good, but takies larger space and costly.US4722943 and US5342689 describes the method for expandable microspheres, and wherein microballoon is mixed with surface barrier coating to prevent from luming in drying steps.But processing aid, as talcum amount is very high, and this have impact on the possibility of chilling.This also produces difficulty in control microsphere expansion degree.CN1882638B, CN101263183A and CN1729087A describe the method for expandable microspheres, and equally wherein microballoon is mixed with surface barrier coating to prevent from luming in expansion step.Meanwhile, the preparation of its expansion gear is complicated.
Above-mentioned ownership Preparation Method all can not get very pure expandable microspheres (ultralight polymer hollow microsphere), the use of product is restricted, the application such as in artificial marble, body solder and engineered wood.Chinese patent (201510483687.3 and 201520594436.8) discloses a kind of thermal current expansion kettle device preparing very pure expandable microspheres, but owing to adopting autoclave to expand, so it is uneven that microballoon blowing agent can be caused to be heated in still, cause the product quality problem of non-homogeneous expansion.
