Description
Technical field
The preparation method of a kind of monolithic vacuum thermal insulation of the present invention plate belongs to external wall outer insulation material technology for building field.
Background technology
At present, for energy-saving material-vacuum thermal insulation plate of building inside and outside wall, leak rate is high, and surface finish is poor, maintenance usefulness is short, and after gas leakage, core separates formation " two skins " with vacuum bag, overlap edge easily produces the problems such as cold-heat bridge.In concrete engineering uses, return factory's ratio large, completion repair rate is high, and " the figure for shadow-play wall " that cold-heat bridge causes is obvious, and above these technological deficiencies and inadequate natural endowment, badly influence construction work progress and quality and heat preservation energy-saving effect.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of tabular core, the preparation method of the vacuum thermal insulation plate that good integrity, leak rate be low, avoid cold-heat bridge.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of preparation method of monolithic vacuum thermal insulation plate carries out according to following steps:
The first step, the making of core plate
A, by the raw material of core plate according to following weight portion proportioning: superfine fibre 70-55 part, poromerics 15-20 part, half closed pore granular material 8-18 part and cementing agent 3-10 part;
B, be 2:1 mix and blend pulping by weight by the raw material of described core plate and water, then extrusion modling, obtains moulding core plate;
C, described moulding core plate is dried to 5-8min at the temperature of 180 ℃-400 ℃, then by the moulding core plate cutting of oven dry and beat equably multiple through holes on the plate face of well cutting, obtain standard core plate;
Second step, loads core plate
To in the through hole of described standard core plate, dose getter, then apply fire prevention adhesives at two plate faces of the standard core plate of filling getter, then put into encapsulated layer and carry out extrusion bondedly, obtain core plate to be packaged;
The 3rd step, vacuumizes encapsulation
Described core plate to be packaged is vacuumized to 5-25min, and vacuum reaches 10
-2-10
-4kPa, then carries out heat sealing and second pulse extruding sealing successively, finally cuts and obtains standard warming plate.
Described superfine fibre is mineral wool, or mineral wool; Described poromerics is silica; Described half closed pore granular material is perlite; Described cementing agent is starch and ripe rubber powder, and the weight part ratio of starch and ripe rubber powder is 1:2.
Described fire prevention adhesive is cloud stone glue for building or environment-friendly type chlorobutyl benzene-free fire-retarded universal glue for building.
Described standard core plate freeze-thaw resistance is more than or equal to 0.1MPa, and impact strength is not less than 2.0J.
The through-hole diameter of described standard core plate is 3-4mm.
Second step loads in core plate at two plate faces of the standard core plate of described filling getter and applies after fire prevention adhesives, then puts into encapsulated layer and carry out extrusion bondedly, and adhesion strength is greater than 0.1MPa.
The beneficial effect that the present invention compared with prior art has is: the warming plate that the present invention makes is except possessing the excellent properties of prior art vacuum heat-insulating plate, made up that the leak rate that prior art and product exist is high, after poor flatness, gas leakage core loose, sink and " two skins " and product thin and thick differs, length not etc., the size defect and the inadequate natural endowment that are not inconsistent.Improve the globality of warming plate, guarantee that warming plate has good energy-saving heat preserving effect, greatly reduce the leak rate in production, transportation and the work progress of warming plate, saved production, application and cost of transportation, make specification, size standard, the standard more of product.The present invention adopts inorganic material to synthesize a kind of sheet material, and mode that to substitute prior art core be powdery has improved planeness and the specification standards of warming plate; Utilize the equally distributed hemispherical projections of plate face of core plate, improve the adhesion strength of warming plate; Adopt a kind of special binder material that core and encapsulated layer are bonded as one, make warming plate there is globality; Adopt core twist drill hole to place getter, science quantity allotted and position, guarantee lasting vacuum; Adopt two sealing modes to reduce leak rate; Adopt special strip warming plate to fill the overlap edge of warming plate, thereby solve the problem of prior art because of the cold-heat bridge formation " figure for shadow-play wall " of overlap edge generation.
