Description

Aerated product with lacing wires and reflective film and manufacturing process Technical Field The invention belongs to the technical field of inflatable products, and particularly relates to an inflatable product with lacing wires and a reflecting film and a manufacturing process thereof. Background The traditional outdoor inflatable product is formed by bonding a whole baffle structure with a cover bottom layer material to form a stable closed structure, or by alternatively bonding one or more TPU films serving as intermediate layers with the cover bottom layer material to form a plurality of mutually communicated air chambers. When the product is used, the product needs to be filled with gas to form a full cavity to isolate a human body from the ground, but when the simple cavity structure is used outdoors, the heat radiation of the human body and the cold flow of the ground are extremely easy to generate strong convection in the cavity, so that the heat is rapidly dissipated. In general, in order to reduce heat dissipation, a reflective or heat-insulating material needs to be added inside the product to improve the heat insulation performance of the product, but the number of layers of the heat-insulating material is limited by the structure, and at most, only 3 reflective layers can be added. The reflection film commonly used in the market at present mainly uses an aluminized film with PET/PE as a base material, the material has good heat reflection performance, but due to the physical properties of the base material, the reflection layer cannot be adhered to the base material and the cover bottom material, so that the structure of the conventional mattress is limited, the reflection film can only be hung through a baffle plate or a bonding point between the TPU film and the cover bottom material, in the conventional structure, the reflection layer is in a horizontal state in the mattress, the material performance is limited, heat dissipation to the outside of the mattress is not prevented, and the heat insulation efficiency of the mattress is low.
