Description
Technical Field
The invention relates to a cold insulation box made of PU materials and vacuum insulation panels.
Background
The existing cold insulation box is formed by splicing a plurality of heat insulation boards, wherein the heat insulation boards are formed by completely coating vacuum heat insulation boards with foaming materials.
The foaming material is generally polystyrene foam (Expanded Polystyrene is called EPS for short), polyurethane rigid foam or the like.
EPS is a lightweight high molecular polymer. The foaming plastic is formed by adding a foaming agent into polystyrene resin, heating and softening the polystyrene resin, and generating gas by the foaming agent. The processing method can be divided into a mode method and an extrusion method according to the foaming mode. The thermal conductivity of polystyrene was 0.116W/(m.K.) at 30 ℃.
Polyurethane foam (PU for short) is a high molecular polymer prepared by mixing isocyanate and polyether as main raw materials under the action of a foaming agent, a catalyst, a flame retardant and other auxiliary agents by special equipment and foaming in situ by high-pressure spraying. Polyurethane foam has both soft foam and hard foam. The soft foam is of an open pore structure, and the hard foam is of a closed pore structure; the rigid polyurethane foam plastic is mainly applied to building external wall heat preservation, roof waterproof heat preservation integration, refrigeration house heat preservation and heat insulation, pipeline heat preservation materials, building boards, refrigeration cars, refrigeration house heat insulation materials and the like.
Vacuum insulation panels or vacuum insulation panels (i.e., VIP, english Vacuum Insulation Panel), the thermal conductivity of VIP can generally be <0.003 watts/(meter-kelvin) at 30 ℃. Under the same conditions, the thermal conductivity of PU is typically an order of magnitude higher than VIP.
The VIP finished product is a flat plate or an arc plate; VIP includes film bags for vacuum coating core materials, which are not abrasion-resistant, impact-resistant; once the membrane bag is broken and leaks air, the VIP is invalid, and the heat conductivity coefficient of the invalid VIP is greatly improved. For this purpose, one or more sides of the VIP are coated with foaming material layers to protect the VIP, the corresponding heat-insulating board is called PU-VIP for short, and the cold-insulating box is made of the PU-VIP.
In the existing cold insulation box made of PU-VIP, two polyurethane foam layers (namely PU layers) are arranged at the splicing ends of two adjacent PU-VIPs, and the electric heating coefficient of the PU layers is one order of magnitude higher than that of the VIP, so that the integral heat insulation performance of the cold insulation box is weakened, and the advantage of the VIP is further exerted, so that the cold insulation effect is greatly improved, and the cold insulation box is a technical problem to be solved in the field.

The hollow plate can meet the requirement of stronger impact resistance, compared with the PU layer, the heat conductivity coefficient of the hollow plate is basically consistent with that of the PU layer, but the hollow plate is adopted to facilitate the rapid production of products, the production period of the products is shortened, and the time for waiting for foaming of the PU layer is not required. Meanwhile, the outline dimension and thickness of the hollow plate are easy to precisely cut and control, so that the consistency of the outline dimension of the batch products is facilitated; under the same thickness condition, the mechanical strength of the hollow plate is obviously higher than that of the PU layer, and the strength of the whole product is improved.
