Description
Technical field
It the utility model is related to a kind of heat insulation foaming paper.
Background technology
With the economic swift and violent development of China, daily necessities of the disposable paper container as application box lunch, house trip
OK, it is easy to carry to become the essential daily necessities in place such as family, restaurant, office.It is its changeable moulding, bright-coloured
Color, be not afraid of the characteristic beaten, liked be subject to many people.But existing disposable paper container is mostly without heat-insulated
Function, if content overheats, heat can be passed out by vessel surface, and when heat is excessive, hand, which contacts, can produce not
It is suitable, or even cusalgia sense can be produced；Conversely, when content is subcooled, the sense of discomfort of supercooling also occurs.
CN200680021764.2 discloses a kind of foam-paperboard laminates, the product for mixing it and preparation method thereof,
By containing extrusion LDPE polymer on wet cardboard, there is provided the paper board material of LDPE coatings, so that the bubble into the utility model
Foam body-paperboard laminates.Once heating the cardboard of LDPE coatings, the moisture in cardboard produces the foaming agent that steam serves as LDPE
And obtain LDPE foams.By the way that on physical adhesion polymer to cardboard, which is adhered on cardboard.
By the surface lamination containing wet paperboard, after heating, foaming, forms the foaming layer of dense uniform, becomes a research and development
Direction.Original way is that have the cardboard of certain humidity, the two-sided lamination in surface, and then entering back into baking oven after printing, shaping adds
Heat foamable.By the way of first lamination, printing, foaming again, because the thickness of ink layer wraps up, bubble can be suppressed after heating to excessive
Go out.But found in actual mechanical process, this mode surface blister is uneven, is also easy to produce orange peel shape.It is two-sided in the prior art
Lamination, what inner surface used makes HDPE+LDPE blend composition laminations, this is to improve the rejection rate of inner surface, and the heating for being is sent out
During bubble, vapor is only overflowed from outer surface, only forms foaming layer in the outer surface of paper, and HDPE fusing points are high, are processed into
During heat-insulated container is made in type, difficult adhesion, imperfect bonding rate height is, it is necessary to special equipment and material, it is difficult to uses to industry
In metaplasia production.
The content of the invention
One of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of heat insulation foaming paper, it is with excellent
Heat insulation, good hand touch be soft and velvet is strong, post-production shaping adhesion is easy, suitable for industrialized production.
What the purpose of this utility model was realized in：
A kind of heat insulation foaming paper, it includes middle paper substrate, interior leaching membrane layer and outer leaching membrane layer, and the interior leaching membrane layer uses
Three-layer co-extruded leaching membrane layer, the three-layer co-extruded lamination are three-layer co-extruded for LDPE/HDPE/LDPE；The three-layer co-extruded material is pressed
Close to the outside order of paper substrate, its quality usage ratio is 1:3-4:1-4.
The outer leaching membrane layer raw material is LDPE and 40-20% the POE plastic blend material of 60-80%.The LDPE plastics melt
Melt index (dg/min) and use 6-7.5.The outer leaching membrane layer raw material is 100%LDPE.
The paper substrate of the centre is cup body paper, and it is 7-11% to control its humidity grammes per square metre accounting.
A kind of preparation method of heat insulation foaming paper, prepares raw material respectively by said ratio, and is respectively placed in using two-sided leaching
In the charging bucket of film machine, on the two sides of paper substrate, lamination, die head temperature are 300-320 DEG C, speed 50-180m/min at the same time,
The lamination amount of the outer leaching membrane layer is 25-50g/m2, it is preferably 30g/m2；
The interior leaching membrane layer uses co-extrusion die head lamination, and lamination amount is 18-35 g/m2, it is preferably 25 g/m2。
After lamination, then in outer leaching membrane layer surface printing, heat up and foam subsequently into baking oven so that outer one layer of leaching membrane layer formation
Fine and closely woven soft foaming layer, the strong good hand touch of velvet, and good heat-insulation effect.
Compared with prior art, the beneficial effects of the utility model are：
The utility model uses the three-layer co-extruded laminations of LDPE/HDPE/LDPE in the two-sided lamination of paper substrate, interior leaching membrane layer,
HDPE plays the role of preventing moisture penetration, and LDPE provides self-styled performance very well, during heating, moisture that middle paper substrate contains
Evaporate, due to the barrier of interior leaching membrane layer, vapor can only be diffused out from outer leaching membrane layer, so as to be formed in outer surface even and fine
Greasy foaming layer.The outer leaching membrane layer of the utility model just has the blend composition of LDPE and POE plastics, and flexibility is good, without using any hair
Infusion, cost is low, pollution is small；The foaming layer formed after heating is good in spongy, feel exquisiteness, heat-proof quality；It is made again heat-insulated
In the bonding process of container, the special equipment of speciality is not required to, suitable for industrialized production.The mode printed after lamination, will not obstruct
Paper substrate moisture evaporation, uniform in foaming, no orange peel shape, good product quality.
