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, be used for the 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 gas leakage back core separates formation " two skins " with vacuum bag, overlap edge is easy to generate problems such as cold and hot bridge.In concrete engineering application, it is big to return factory's ratio, and the completion repair rate is high, and " the figure for shadow-play wall " that cold and hot bridge causes is obvious, more than 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 provides a kind of tabular core in order to overcome the deficiency of prior art, the preparation method of the vacuum thermal insulation plate that good integrity, leak rate be low, avoid cold and hot bridge.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts does, 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, with the raw material of core plate according to following weight portion proportioning: superfine fibre 70-55 part, poromerics 15-20 part, semi-closure hole granular material 8-18 part and cementing agent 3-10 part;
B, with the raw material of described core plate and water by weight than for 2:1 is mixed into slurry, extrusion modling then obtains moulding core plate;
C, said moulding core plate is dried 5-8min under 180 ℃-400 ℃ temperature,, obtain standard core plate then with the moulding core plate cutting of oven dry and on the plate face of well cutting, beat a plurality of through holes equably;
In second step, load the core plate
Dose getter in the through hole with said standard core plate, two plate faces at the standard core plate of filling getter apply the fire prevention adhesives then, put into encapsulated layer again and carry out extrusion bondedly, obtain core plate to be packaged;
In the 3rd step, vacuumize encapsulation
Said core plate to be packaged is vacuumized 5-25min, and vacuum reaches 10
-2-10
-4KPa carries out heat sealing and second pulse extruding sealing then successively, cuts at last and obtains the standard warming plate.
Said superfine fibre is a mineral wool, or mineral wool; Said poromerics is a silica; Said semi-closure hole granular material is a perlite; Said cementing agent is starch and ripe rubber powder, and the weight part ratio of starch and ripe rubber powder is 1:2.
Said fire prevention adhesive is cloud stone glue for building or environment-friendly type chlorobutyl benzene-free fire-retarded universal glue for building.
Said standard core plate freeze-thaw resistance is more than or equal to 0.1MPa, and impact strength is not less than 2.0J.
