Plastic extrusion and welding heat-insulation plate with inner lining and assembly method thereof

Abstract

The invention discloses a plastic extrusion welding lining thermal baffle and an assembly method thereof. The plastic extrusion welding lining thermal baffle is provided with a plate body, a bulge installed on the plate body, and a jointing port installed on the plate body; and the jointing part is provided with a layer of soft plastic on a hard plastic substrate. The assembly method includes the following steps that: an extrusion welding part is cooled after heating and softening soft plastic and / or extruded plastic welding material so as to be connected integrally, and the welding part is the jointing port at the jointing position of hard plastic and soft plastic. The invention can be used as lining thermal baffles of containers or other refrigerating boxes; in terms of the steel structure of containers or other refrigerating boxes, partial polyethylene thermal baffle is used for replacing internal metal structure, thereby reducing the weight itself, being propitious to transportation, and having strong strength, good buffering performance, heat-insulating performance and sound insulation performance, and difficult corrosion.

Description

technical field [0001] The present invention relates to heat and sound insulation boards used in the process of food preservation and methods of making and using them, in particular to a heat insulation board for a foaming area used in refrigerated and frozen containers or the like and an assembly method thereof, specifically It is an improvement to the heat insulation board in the foaming area of ​​the existing refrigerated container. Background technique [0002] In modern logistics, refrigerated containers are often used to transport frozen goods. In order to maintain a specific temperature during transportation, some heat insulation boards are usually installed on the inner wall of the container, and foaming is performed on the heat insulation boards to form a certain thickness of foam. Layer, to maintain the temperature inside the box. [0003] One end of the refrigerated container body is generally an openable door, and the other end is generally provided with a refri...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to solve the technical problems existing in the prior art that the foam layer and the heat insulation board are not firmly bonded, easy to fall off, the heat insulation effect is poor, and the construction of the heat insulation board on the inner wall of the refrigerator is complicated, and the provided A plastic extruded welded inner liner heat insulation board with firm foaming layer and good thermal insulation effect and its manufacturing and using methods. The plastic extruded welded inner lined heat insulation board of the present invention can be used as heat insulation for containers or other similar objects Layered body, which is beneficial to reduce the weight of the container or other similar objects, which is convenient for transportation, has good heat and sound insulation performance, and is not easy to corrode
