Abstract

The invention discloses a thermal and cold preservation composite material, which is composed of an OPP printing film, a first LDPE layer, a first EPE layer, a second LDPE layer, an HDPE layer, a second EPE layer, a third LDPE layer, and a VMPET layer from outside to inside in order. Compared with the prior art, the invention has the advantages that: with good thermal and cold preservation properties, the composite material can be made into thermal preservation cups or cold preservation cups and thermal preservation bags or cold preservation bags, only by placing drink-holding ordinary cups into the thermal preservation bags or cold preservation bags can thermal preservation of hot drinks in winter and cold preservation of cold drinks in summer be achieved, there is no need to buy thermal preservation cups additionally, and the disadvantages that thermal preservation cups are expensive in price, bad for human health, unsuitable to hold drinks and brew tea, and inconvenient to clean are solved.

Description

A kind of insulation cold insulation composite and preparation method thereof

Technical field

The present invention relates to a kind of composite, specifically relate to a kind of insulation cold insulation composite and preparation method thereof.

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, the cup that common material is made can only be used for carrying liquid, can not play the effect of insulation cold insulation, so people generally drank water with thermos cup when winter, cool off very soon to prevent boiling water.But the soya-bean milk that picture is sold, milk etc. consider that Cost Problems is not suitable for being put in thermos cup and together sells, and put common cup and can cool off very soon again.Same, the cold beverage in summer, also not having preferably, cool preservation cup holds.In addition, the stainless steel of thermos cup contacts with water for a long time, can cause the leaching ability of heavy metal in the stainless steel to enter human body, also can be detrimental to health.

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 invention provides a kind of insulation cold insulation composite.

The present invention also provides above-mentioned insulation cold insulation composite manufacture method.

Technical scheme: in order to realize above purpose, a kind of insulation cold insulation composite of the present invention is comprised of OPP print film, a LDPE layer, an EPE layer, the 2nd LDPE layer, HDPE layer, the 2nd EPE layer, the 3rd LDPE layer, VMPET layer from outside to inside successively.

The thickness of described OPP print film is 15 ~ 40um; The thickness of the one EPE layer is that the thickness of 0.5 ~ 1.5mm, HDPE layer is 20 ~ 50um; The thickness of the 2nd EPE layer is 0.5 ~ 1.5mm; The thickness of VMPET layer is 10 ~ 15um;

The thickness of a described LDPE film is 20 ~ 50um; The thickness of the 2nd LDPE film is 20 ~ 50um; The thickness of the 3rd LDPE film is 20 ~ 50um.

Make the method for above-mentioned insulation cold insulation composite, concrete steps are as follows:

A, pattern is printed on becomes the OPP print film on the OPP film;

B, LDPE is extruded under 320～350 ℃ of conditions, drench between an EPE layer and HDPE layer both are closed in pouring, form the 2nd LDPE layer;

C, LDPE is extruded under 320～350 ℃ of conditions, drench between the another side of an EPE layer and OPP print film both are closed in pouring, form a LDPE layer;

D, LDPE is extruded under 320～350 ℃ of conditions, drench between the 2nd EPE layer and VMPET layer both are closed in pouring, form the 3rd LDPE film;

E, the another side of the 2nd EPE layer and the another side of HDPE layer are sewed up, made described insulation cold insulation composite.

The application of above-mentioned insulation cold insulation composite in thermos cup.

Beneficial effect: the present invention compared with prior art has the following advantages: insulation cold insulation performance is good, can be made into thermos cup or cool preservation cup, also can make insulated bag or cold-keeping bag, the conventional cup that only needs to hold drink is put into this insulated bag or cold-keeping bag, the hot drink that can be incubated winter, also can cold insulation the ice drink in summer, do not need to buy in addition thermos cup, solved employing thermos cup price, unfavorable health, should not fill drink, the shortcoming such as should not make tea, be inconvenient to clean.
