Description
Technical field
The present invention relates to a kind of inorganic compounding core and preparation method, be specifically related to inorganic compounding core and preparation method that a kind of glass fibre cotton and glass dust mix.
Background technology
Vacuum heat-insulating plate is based on vacuum insulation principle, realizes thermal insulation by improving in plate vacuum filling porous low thermal conductivity material to greatest extent, becomes the material that current heat conductivity is minimum.
Core itself should be porous material and has low heat conductivity, remaining in the space of some gas molecules in vacuum heat-insulating plate for limiting, thus stoping air heat convection current and conduction of heat, being the core texture of vacuum heat-insulating plate.Meanwhile, core also should be played a supporting role, it is to avoid packaging film outside under vacuum shrinks, caves in, as supporting core, it is necessary to bear the pressure of about 98KPa.The heat preservation and insulation of vacuum heat-insulating plate, fire protecting performance, endurance quality are heavily dependent on selected core.
Current core or cotton felt technology are mainly based on glass fibre cotton.But, in the material felt being made up of glass fibre merely or core, the grasp force between glass fibre is realized by the winding effect between long glass fibre completely.Therefore, the tearing strength of glass fibre core is limited.It addition, the rebound degree of the material felt being made up of glass fibre merely or core is excessive, once efficiently Obstruct membrane punctures, the insulating fibre material in vacuum heat-insulating plate can produce hollowing phenomenon, has severely impacted the serviceability of vacuum heat-insulating plate.It addition, the price of glass fiber material is generally higher, limit its extensive use.
Additionally, add the method such as powder body, zeolite in glass cotton can improve core overall performance, but zeolite isodensity is relatively big, preponderance, core can be made too heavy, affect the use scope of vacuum heat-insulating plate；Paris white then particle diameter is excessive, affects glass cotton and is mutually wound around with it and combines.
Summary of the invention
The purpose of the present invention is intended to overcome the existing technical deficiency of inorganic compounding core, provide a kind of advanced composite material (ACM) core mutually adulterated by glass fibre cotton and glass dust, glass powder is unformed hard particles, it it is a kind of anti-zoned high transparency powder of easily polishing, its particle diameter is little, good dispersion, transparency high, therefore glass fibre and glass dust are combined, for the preparation of novel core.
The technical scheme is that and provide, for realizing the purpose of the present invention, the inorganic compounding core that a kind of glass fibre cotton and glass dust mix, it is characterized in that the thin core that described core is mixed rear gained mutually by glass fibre cotton and glass dust is formed by stacking from level to level, and core easily processes, or punching or corner cut or smooth.
Described core, it is characterised in that described glass fibre cotton can be flame cotton, centrifugal cotton or their combination.
Described core, it is characterised in that described glass dust can be lead bearing glass powder or not lead bearing glass powder, and mean diameter is 0.5 ~ 6.0 micron.
Described core, it is characterised in that described glass dust accounts for the 10 ~ 40% of weight.
The preparation method that the invention also discloses the inorganic compounding core that a kind of glass fibre cotton mixes with glass dust, it is characterised in that include the step of following order:
(1) adding in troughing by glass cotton and glass dust, with water for dispersant and solvent, it is 0.1 ~ 3% that making beating obtains slurry concentration；
(2) glass cotton diluted and glass powder paste are sent into storage stock tank；
(3) slurry stored in stock tank is sent into flow box, adopt forming net to glass cotton and glass powder paste dehydration forming, form blank；
(4) adopt pressure roller that glass cotton and glass powder paste blank are carried out longitudinally, laterally surfacing, thickness is adjusted simultaneously, makes glass cotton consistent with glass powder paste blank thickness；
(5) glass cotton and glass powder paste blank that complete shaping are put in negative pressure of vacuum environment, remove the moisture of 70% ~ 90% in blank；
(6) then the glass cotton and glass powder paste blank of removing moisture being sent into baking and curing in baking box, baking the temperature inside the box controls at 250 ~ 400 DEG C, and baking time is 2 ~ 20 minutes；
(7) dried core is cut, as required core is processed, more blocks of thin core is overlapped mutually, it is thus achieved that the inorganic material finished product core of blocks of different size and model.
Application effect: the present invention compared with prior art, has the advantage that
(1) the glass dust particle diameter that the present invention is affiliated is little, good dispersion and stable chemical performance, can improve the combination property of core with glass fibre cotton after mixing；
(2) the core density that glass fibre cotton of the present invention mixes mutually with glass dust is low, lightweight；
(3) inorganic compounding core of the present invention, due to the addition of glass dust so that this core can be good at improving the phenomenon occurring expanding when vacuum heat-insulating plate uses, and reduces the expansion rate after wall on vacuum heat-insulating plate for building.
Accompanying drawing explanation
Fig. 1 is the inorganic compounding core micro-structure diagram that a kind of glass fibre cotton mixes with glass dust.
Detailed description of the invention
Below in conjunction with specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention, after having read the present invention, the amendment of the various equivalent form of values of the present invention is all fallen within the application claims and is limited by those skilled in the art.
