Abstract
The utility model discloses a heat-preserving cold-preserving composite material sequentially comprising an oriented polypropylene (OPP) printed film, a low-density polyethylene (LDPE) layer, non-woven fabric, VMPET layer, and an expandable polyethylene (EPE) layer from up to bottom. Compared with the prior art, the heat-preserving cold-preserving composite material has the advantages of being good in heat-preserving and cold-preserving property, wide in use range, capable of being made into a heat-preserving cup or a cold-preserving cup, a heat-preserving bag or a cold-preserving bag, capable of keeping hot foods warm in winter and keeping cold foods cold in summer, capable of being used for containing objects and performing heat-preserving and cold-preserving functions, being simple in manufacture method, and capable of achieving industrial mass production.
Description
Technical field
The utility model relates to a kind of material, specifically relates to a kind of insulation cold insulation composite.
Background technology
Along with growth in the living standard, people require also more and more higher to the material of daily necessities, common material can not satisfy people's demand, for example, office's white collar all can order takeaway in lunch, dinner and teatime, but how to cool off when delivering to when taking out, especially in winter, carryout has also just lost its original taste.The food such as the cold drink in summer, beverage also need to prevent from dissolving in the process of transporting and keeps iced with sending the insulation bag outside, but the take-away bag that common material is made, cup etc. can only be used for article-containing, can not play the effect that is incubated cold insulation.
Therefore, the research of functional composite is become the demand of society.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the utility model provides a kind of insulation cold insulation composite, to solve the heat loss such as food or article, to affect shortcoming edible or that use.
The utility model also provides the preparation method of above-mentioned insulation cold insulation composite.
Technical scheme: in order to realize above purpose, a kind of insulation cold insulation composite described in the utility model, it is comprised of OPP print film, LDPE layer, nonwoven, VMPET layer, EPE layer from top to bottom successively.The thickness of described OPP print film is 12 ~ 30um; The thickness of described LDPE layer is 20 ~ 50um; The thickness of described nonwoven is 0.15 ~ 0.4mm; The thickness of described VMPET layer is that the thickness of 10 ~ 20um, described EPE layer is 0.6 ~ 2mm.
Make the method for above-mentioned insulation cold insulation composite, comprise the steps:
A, pattern is printed on respectively becomes the OPP print film on the OPP film;
B, LDPE is extruded under 320～350 ℃ of conditions, drench both are closed in pouring, form the LDPE film;
C, be 100～200 ℃ with VMPET layer and EPE layer in temperature, pressure is to carry out pressing under 50～80kg condition;
D, the another side of nonwoven and the another side of VMPET layer are adjacent to stitching, are described insulation cold insulation composite.
The application of above-mentioned insulation cold insulation composite in taking out the insulation bag.
Beneficial effect: the utility model compared with prior art has the following advantages: insulation cold insulation performance is good, the scope of application is extensive, can be made into thermos cup or cool preservation cup, insulated bag or cold-keeping bag, the hot food that can be incubated winter, also can cold insulation the ice confectionery in summer, also can be used for article-containing, play the effect of insulation cold insulation; Preparation method is simple, can realize large-scale industrialization production.
