The utility model can ensure that the original polyurethane heat-insulating board does not change or enhance the heat-insulating effect under the condition of reducing the thickness; the polyurethane adhesive layers coated on the upper surface and the lower surface of the aluminum foil can enable the aluminum foil and the polyurethane layers to have good adhesive effect.

Description

Polyurethane board

Technical Field

The utility model relates to a polyurethane building materials field, concretely relates to polyurethane board.

Background

Polyurethane has been widely used in various industries because of its excellent properties. The polyurethane board has the advantages of light weight, low water absorption, good heat insulation effect and the like, and is generally used for the construction of a refrigeration house, and the longer polyurethane board is easy to break off in the transportation and use processes.

Meanwhile, in the prior art, most of the polyurethane plates are lapped by adopting male and female buckles or eccentric hooks and lock catches, and sealing glue is filled in gaps. However, under the condition that the temperature of the refrigeration house is very low, the sealant and the polyurethane are not the same substance, so that the technical problem of poor sealing between plates can be caused due to different cold shrinkage ratios, the heat insulation effect is reduced, and energy is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a difficult rupture, the better polyurethane board of sealing performance simultaneously especially is fit for the freezer that the temperature requirement is very low.

In order to achieve the above object, the utility model provides a polyurethane board, including the polyurethane panel body, the inside aluminium foil layer that is equipped with the symmetry of panel body, the upper and lower surface coating on aluminium foil layer has polyurethane adhesive layer, the inside strengthening rib that still is equipped with of panel body, the strengthening rib is the reinforcing bar of cross arrangement.

As the utility model discloses an it sets up preferably, polyurethane board both ends intermediate position is equipped with circular boss and rather than the circular recess that corresponds circular boss is equipped with two arc recesses respectively with circular recess both sides, is equipped with the overlap joint recess in arc recess one side of one end wherein, and arc recess one side of the other end is equipped with the overlap joint boss that corresponds with the overlap joint recess.

As the preferred setting of the utility model, both ends arc recess forms the column cavity, pour into liquid polyurethane into in the column cavity.

As the utility model discloses an optimized setting, the overlap joint recess that both ends correspond can be any one of square, trapezoidal or triangle-shaped with the overlap joint boss.

The utility model has the advantages that:

(1) the polyurethane board has high compressive strength and rupture strength and simple processing.

(2) The connection between the polyurethane boards is more compact, the sealing performance is better, the structure is simple, and the sealing performance requirement of the refrigerator with low temperature requirement can be met.

(3) The aluminum foil has a certain blocking effect on cold air flow and hot air flow, so that the heat preservation effect of the original polyurethane heat preservation plate is not changed or enhanced under the condition of reducing the thickness; the polyurethane adhesive layers coated on the upper surface and the lower surface of the aluminum foil can enable the aluminum foil and the polyurethane layers to have good adhesive effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.

Examples

Referring to fig. 1-2, in the embodiment of the utility model provides a polyurethane board, including polyurethane plate body 1, 1 inside aluminium foil layer 2 that is equipped with the symmetry of plate body, the upper and lower surface coating on aluminium foil layer 2 has polyurethane adhesive layer, and 1 inside strengthening rib 3 that still is equipped with of plate body, strengthening rib 3 are the reinforcing bar of cross arrangement.

As the utility model discloses preferred setting, furtherly, 1 both ends intermediate position of polyurethane plate body is equipped with circular boss 4 and rather than the circular boss 5 that corresponds, is equipped with two arc recess 6 respectively in circular boss 4 and circular recess 5 both sides, is equipped with overlap joint recess 7 in arc recess 6 one side of one end wherein, and arc recess 6 one side of the other end is equipped with the overlap joint boss 8 that corresponds with overlap joint recess 7.

As the utility model discloses preferred setting of embodiment, furtherly, both ends arc recess 6 forms the column cavity, pour into liquid polyurethane into in the column cavity, wait to expand, cool off postcure.

As the preferred arrangement of the utility model, the lapping grooves 7 and the lapping bosses 8 corresponding to the two ends can be any one of the square, trapezoid or triangle.

Fixing a plurality of crossed thin steel bars on the planes of the middle positions of two sides of a die cavity for producing the polyurethane plate, then injecting a layer of liquid polyurethane into the die cavity, covering an aluminum foil layer after curing and molding, then continuing to inject a second layer of liquid polyurethane, curing and molding, covering the aluminum foil layer again, and finally injecting a third layer of liquid polyurethane, and curing and molding.
