Thermal insulation can, thermal insulation can plate and manufacturing method of thermal insulation can plate

Abstract

The invention discloses a novel thermal insulation can, a thermal insulation can plate and a manufacturing method of the thermal insulation can plate. The method comprises the following steps: foaming a mixed material of 95 percent of polystyrene (PS) granules and 5 percent of polyethylene (PE) granules, molding the mixed material into plate cores output in a rolled material form, and curing the plate cores in the rolled material form; mounting two rolls of cured plate cores and two rolls of aluminized films onto a casting compound machine, and fusing the aluminized films and the plate cores together through heating extrusion of an equipment fusion mechanism, thereby forming a double-layer aluminized film thermal insulation can plate; and cooling the plate, cutting and setting, thereby obtaining the novel thermal insulation can plate finally. The thermal insulation plate is good in sealing property and thermal insulation property, protects the ecological environment, and is convenient to use and low in cost.

Description

technical field [0001] The invention relates to the field of heat preservation, in particular to a novel heat preservation box for heat preservation and freshness preservation, a plate of the heat preservation box and a manufacturing method thereof. Background technique [0002] In the packaging, warehousing, and logistics of certain perishable or deteriorating foods or goods such as fresh milk, vegetables, fruits, seafood, seedlings, cold food in summer, etc., or in the last mile delivery of original packaging products, These foods or goods need to be kept in an incubator to achieve heat preservation and freshness. The foam box used for heat preservation and freshness preservation in the prior art has poor heat preservation and freshness preservation effect, high cost of packaging materials, is not environmentally friendly, and has the disadvantage that it cannot be folded, resulting in increased costs for merchants in various links such as warehousing and logistics. The s...

Problems solved by technology

In the prior art, the foam box used for heat preservation and preservation has poor heat preservation and freshness preservation effect, and the cost of packaging materials is high, not environmentally friendly, and has the disadvantage that it cannot be folded, resulting in increased costs for merchants in various links such as warehousing and logistics.

The solution can only be to purchase less and more frequently, and the purchase volume is very small under the same transportation cost
