Abstract
The invention provides a fabrication method of a polyurethane insulation board of a mortuary refrigerator. The fabrication method comprises the following steps of: respectively connecting two ends of two parallel stainless steel plates with a baffle plate to form a cavity, wherein, an injection hole is reserved at one of the baffle plates, and the surfaces of the two stainless steel plates of the cavity abut against a pressure plate on a press machine so as to prevent deformation of the two stainless steel plates; and then injecting polyurethane into the cavity via the injection hole under the pressure action so as to finally obtain the high-density polyurethane insulation board after the polyurethane is expanded and cured. The fabrication method is simple and easy for implementation; and by adopting the method, the density of the polyurethane insulation layer is increased and the insulation effect of the insulation layer is improved.
Description
Technical field
The present invention relates to a kind of preparation method of warming plate, relate in particular to a kind of preparation method of peaceful cabinet polyurethane thermal insulation board.
Background technology
In order to keep the temperature of peaceful cabinet, cut down the consumption of energy, need to use warming plate to be incubated usually; Common warming plate all is that direct filled polyurethane reaches heat preservation effect in the cavity that is employed between the two-layer corrosion resistant plate, because of polyurethane all is under normal pressure, directly to fill to get in the cavity at present, treats its curing then; Cause polyurethane insulation coating density little, and be easy to generate bubble, corresponding heat insulation effect is poor; Big energy-consuming increases use cost, reduces product competitiveness.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of peaceful cabinet polyurethane thermal insulation board, changed the method for traditional fabrication polyurethane thermal insulation board, improved the density of heat-insulation layer, reduced the bubble in the heat-insulation layer, improved heat insulation effect.
The present invention realizes like this; Method step is: the two ends of two parallel corrosion resistant plates are connected with baffle plate respectively and form a cavity, and one of them baffle plate leaves hand-hole, and two corrosion resistant plate surfaces of said cavity are near the pressing plate on the press; Prevent two corrosion resistant plate distortion; Then polyurethane is injected in the cavity through hand-hole under pressure, pressure generally is controlled at 8-15MPa, treats can obtain highdensity polyurethane thermal insulation board behind the polyurethane expansion curing.
Technique effect of the present invention is: preparation method is simple, realizes easily, has improved the density of polyurethane insulation coating, has increased the heat insulation effect of heat-insulation layer.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Corrosion resistant plate 2, polyurethane insulation coating in the drawings, 1.
The specific embodiment
As shown in Figure 1; The present invention realizes like this; Method step is: the two ends of two parallel corrosion resistant plates 1 are connected with baffle plate respectively and form a cavity, and one of them baffle plate leaves hand-hole, and two corrosion resistant plates 1 of said cavity are near the pressing plate on the press; Prevent 1 distortion of two corrosion resistant plates; Then polyurethane is injected in the cavity through hand-hole under pressure, pressure generally is controlled at the 8-15MPa scope, treat polyurethane under HTHP, foam fully and solidify after can obtain highdensity polyurethane thermal insulation board 2.
