Abstract

The invention provides a manufacture method of a core material of a vacuum heat insulation plate through aiming at the problem of high cost of the core material of the vacuum heat insulation plate in the prior art. The method comprises the following steps: rock wool fiber pulping and net covering; shaping and rolling; vacuum dehumidifying; and cooling and material forming. The invention adopts the rock wool fiber, and the produced core material of the vacuum heat insulation plate can satisfy performance required by the core material of the vacuum heat insulation plate , and also has the obvious advantages of fire resistance, sound absorption and the like. More importantly, the production process is simple, and the invention can meet the requirement of fast mass production of building industry.

Description

Manufacture method of core material of vacuum heat insulation plate
Technical field
The present invention relates to a kind of constructional materials preparation method, be specifically related to the used for building exterior wall manufacture method of core material of vacuum heat insulation plate.
Background technology
The core material of vacuum heat-insulating plate is generally selected porous media material, as powdered silica, aeroge, rock wool fibers or microvoid polyurethane, core has the support structure effect, prevent that vacuum heat-insulating plate shrinks under vacuum condition, it is flat to collapse, prevent thermal-radiating generation besides, the heat conducting generation of its three minimizing is because this is as porous material, contact area is little, can effectively reduce the heat radiation that conduction of heat takes place.The prerequisite characteristic of core is an open-celled structure, so that gas is found time, the arrangement of micropore simultaneously should make the structure contact point in the material few as far as possible, to reduce the solid thermal conduction.
At present European countries' building trade selects core mostly to be aerosil greatly with vacuum heat-insulating plate, and this material satisfies above-mentioned all characteristic requirements, yet that shortcoming is a price is more expensive, and cost is higher.
Summary of the invention
The present invention is directed to the high problem of cost that the prior art core material of vacuum heat insulation plate exists, a kind of manufacture method of core material of vacuum heat insulation plate is provided.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of manufacture method of core material of vacuum heat insulation plate comprises the steps:
A, with rock wool fibers making beating online;
B, shaping roll extrusion;
C, vacuum dehumidifying;
D, cooling are become a useful person;
Described A step comprises the steps:
A1, to choose diameter be that 3-10 μ m, water content are that 1-20%, size are the rock wool fibers of 0.2-5%;
Pour in the slurry can after A2, Jia Shui stir, be delivered to head box then, being diluted to concentration is 0.5-1.2%;
A3, send into flow box, knit forming net, THICKNESS CONTROL is surfed the Net behind 1-25mm;
Further, comprise the steps: in the C step of the present invention
C1, under vacuum condition, take out part water, make sheet material slurries water content be controlled at 10-60%;
C2, send into the drying in oven moulding, temperature is controlled at 250-500 ℃ in the baking oven, and drying time is controlled at 6-10min.
Further, comprise the steps: in the D step of the present invention
D1, be cooled to normal temperature;
D2, cut periphery on request, make the standard core.
The percentage composition that relates among the present invention is all counted by weight percentage.
Compared with prior art, advantage of the present invention and good effect are: owing to adopt rock wool fibers, rock wool fibers in the core is to have open-celled structure, so that gas is found time, can satisfy the performance that all needs of core material of vacuum heat insulation plate possess, the arrangement of micropore simultaneously makes the structure contact point in the material less, thereby reduce the solid thermal conduction, remarkable advantages such as that rock wool fibers also has is fire-retardant, sound-absorbing, the more important thing is that its production technology is simple, the existing core of price reduces by more than 50, and can satisfy the quick requirement of mass production of building trade.
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Embodiment one, and the present embodiment core material of vacuum heat insulation plate is made and comprised the steps:
A, choose that diameter is that 3-5 μ m, water content are 8.0%, size is 0.02% rock wool fibers, adds water and stirs, and pours in the slurry can through falling stock pump, through beating pump slurries is delivered to head box, being diluted to concentration is 0.5%; Enter flow box, the system forming net, controllable thickness is surfed the Net behind 5.0mm;
B, shaping roll-in: make Liu's slurries even, stable, slurries are layering;
C, vacuum dehumidifying: in vacuum process, take out part water, make the water content of sheet material slurries before entering baking oven be controlled at 15%; Temperature is controlled at 300 ℃, and the time of oven dry is controlled at 3min, with the sheet material drying forming;
D, cooling: to be cooled to normal temperature, cut periphery on request, make the thickness of sheet material reach the standard plate of 5mm.
Embodiment two, and the present embodiment core material of vacuum heat insulation plate is made and comprised the steps:
A, choose that diameter is that 4-7 μ m, water content are 10%, size is 0.08% rock wool fibers, adds water and stirs, and through pouring in the slurry can to stock pump, through beating pump slurries is delivered to head box, is diluted to 0.8%; Enter flow box, the system forming net, controllable thickness is surfed the Net behind 10mm;
B, shaping roll-in: make the stream slurries even, stable, unanimity, slurries are layering;
C, vacuum dehumidifying: in vacuum process, take out part water, make the water content of sheet material slurries before entering baking oven be controlled at 55%; Temperature is controlled at 400 ℃, and the time of oven dry was controlled at 4 minutes, with the sheet material drying forming;
D, cooling: to be cooled to normal temperature, cut periphery on request, make the thickness of sheet material reach the standard plate of 10mm.
Embodiment three, and the present embodiment core material of vacuum heat insulation plate is made and comprised the steps:
