Description
Technical field
The utility model relates to a kind of equipment preparing super-light fill material.
Background technology
Microballoon blowing agent (getting final product heat-expandable microsphere) is known in the prior art, and describe in detail in US3615972, EP486080, EP566367, EP1067151, ZL201210241564.5, ZL201210241578.7, CN201280073857.5 and CN2012100109302.3, these files combine at this with for referencial use.Xi Neng chemical science and technology (Shanghai) Co., Ltd. can provide the microballoon blowing agent of various different expansion temperature, and form has dry powder and wet pulp two kinds.In this microballoon blowing agent, 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 blowing agent effectively to expand, general diameter increases about 3 to 5 times, obtains super-light fill material (namely thermally expanded microballoon blowing agent goods).
Unexpanded and thermally expanded microballoon blowing agent (i.e. super-light fill material) can be applied in various field.Such as, dry thermally expanded microballoon blowing agent 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 super-light fill material, usually stores with moisture form, can be applied in many products, as water paint, thermal printing paper, porous ceramics and emulsion etc.
Transport super-light fill material often needs very large space, exactly because also this reason super-light fill material end user usually purchases unexpanded microballoon blowing agent, Expansion on site or directly unexpanded microballoon blowing agent is joined in production stage for the preparation of final products.
High temperature needed for complete expandable microspheres blowing agent thus can cause causing the thermoplastic housing of microballoon mutually to bond and the problem of luming because expanding.This needs to provide a kind of method and apparatus for the preparation of expandable microspheres blowing agent, wherein degrees of expansion can be controlled, likely to provide the super-light fill material 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 super-light fill material, thus save transport space and cost.
The method and apparatus of many patents to expandable microspheres blowing agent is all mentioned.As US Patent No. 5484815 and US7192989 have set forth the method and apparatus of applicable expansion dry powder microballoon blowing agent.And US Patent No. 4513106 proposes the method and the device that are applicable to expandable microspheres blowing agent slurry, its action principle in microballoon blowing agent slurry, introduces steam and produces enough pressure heating microballoons, it is made to have certain expansion at least, then the microballoon blowing agent 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 expandable microspheres blowing agent in slurry form can solve direct expansion dry powder microballoon blowing agent 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 expandable microspheres blowing agent, 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 blowing agent, and wherein microballoon is mixed with surface barrier coating to prevent from luming in expansion step.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 blowing agent, 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.
Chinese patent CN204172262U and CN104325593 discloses a kind of devices and methods therefor preparing emulsion physical sensitization Foamex microballoon, and the method needs to add machine oil, paraffin, silicone oil or their mixture.
All there is the super-light fill material that can not simultaneously be applicable to prepare different model and different conditions in above-mentioned ownership Preparation Method, such as prepares dry powder, moisture or containing the super-light fill material of oil condition respectively, to meet different application.
