Description
Technical field
This utility model relates to one expandable microspheres foaming agent preparation facilities.
Background technology
It is known in the prior art that microsphere foaming agent (gets final product heat-expandable microsphere), and in US3615972, EP486080, EP566367, EP1067151, ZL201210241564.5, ZL201210241578.7, detailed description in 201280073857.5 and 2012100109302.3, these files combine by reference at this.Xi Neng chemical science and technology (Shanghai) Co., Ltd. can provide the microsphere foaming agent of various different blowing temperature, and form has dry powder and wet pulp two kinds.In this microsphere housing, foaming agent is wrapped in thermoplastic housing with capsule form.Once heating, foaming agent evaporation produces internal pressure, simultaneously along with housing softens, causes that microsphere effectively foams, and general diameter increases about 2 to 5 times.
Thermoplastic microspheres that is that do not foam and that foamed can be applied in various field.Such as, the dry microsphere foamed can be applied in emulsion as sensitizer, it is also possible to is filled in solvent-based paints, coating and various thermosetting plastics (such as artificial marble, body solder, engineered wood) as light filling thing.Wet foam microspheres, generally starches form with aqueous suspension and stores, it is possible to be applied in many products, such as water paint, thermal printing paper, porous ceramics and emulsion etc..
Transport foam microspheres and generally require very big space, exactly because also this reason foam microspheres end user usually purchases the expandable microspheres not foamed, foam-in-place the or directly expandable microspheres not foamed is joined and be used in production stage preparing final products.
Due to the high temperature needed for the heat-swellable microsphere that foams completely thus can cause because the problem causing the thermoplastic housing of microsphere mutually to bond and to lump that foams.This needs to provide a kind of method and apparatus for preparing foaming thermo-expandable microspheres, wherein foaming degree can be controlled, to be likely to provide the foam microspheres of different densities, they simply and only need less space simultaneously, relatively cheap, and be prone to be used by end user, and owing to foam microspheres is used on the spot, thus saving transport space and cost.
Foamed thermoplastic expandable microspheres method and apparatus is all mentioned by many patents.As US Patent No. 5484815 and US7192989 elaborate to be suitable for the method and apparatus that expandable microspheres dry powder foams.And US Patent No. 4513106 proposes to be suitable for method and the device of microsphere slurries foaming, its action principle is to introduce steam in expended microsphere slurry and produce enough pressure heating microspheres, it is made to have at least certain expansion, then the microsphere of microdilatancy leaves pressure span with the speed of at least 1m/s, owing to pressure reduces, microsphere is expanded further.Although the method that US4513106 patent proposes foaming and intumescing microsphere in slurry form can solve direct foam microspheres dry powder and cause the phenomenon that around dust is many, but the microsphere slurries foam process described in US4513106 patent is also to be further improved.EP0348372 discloses a kind of technique preparing expanded thermoplastic's microsphere, wherein betides on conveyer belt.Described process operation is good, but takies larger space and costly.US4722943 and US5342689 describes the method for foam microspheres, and wherein microsphere 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 probability of chilling.This is also controlling to produce on microsphere foaming degree difficulty.CN1882638B, CN101263183A and CN1729087A describe the method for foam microspheres, and microsphere is mixed with surface barrier coating to prevent from luming in foaming step likewise of which.Meanwhile, its foam device preparation complexity.
Above-mentioned ownership Preparation Method all can not get very pure foam microspheres so that the use of product is restricted, such as the application in artificial marble, body solder and engineered wood.
