Abstract

The utility model relates to novel composite heterogeneous paper, which is characterized by comprising a substrate layer consisting of silica powder and high-density polyethylene, an ethylene-acrylic acid modified copolymer layer compounded on the upper surface of the substrate layer, and a metallocene high-density polyethylene layer compounded on the lower surface of the substrate layer. The novel composite heterogeneous paper has a good moisture-proof effect and high tensile property, and is stable and durable. In addition, the plant fiber is not required; lots of wood resources are saved; the novel composite heterogeneous paper is environment-friendly; and meanwhile, by the silica powder, waste industrial silica powder raw materials can be recycled, so that the waste materials are changed into valuable, and an environment-friendly effect is achieved by recycling the waste.

Description

The heterogeneous paper of a kind of NEW TYPE OF COMPOSITE

Technical field

The utility model relates to the field of papermaking technology, refers in particular to the heterogeneous paper of a kind of NEW TYPE OF COMPOSITE.

Background technology

Paper is a product indispensable in the modern industrial society, and the making of existing paper generally all adopts timber, herbaceous plant etc. as material, but along with the demand of paper constantly expands, limited resources such as timber are to satisfy the demand of papermaking.And for papermaking immoderate felling also is the heavy damage balance of nature to resources such as forests, and influence human kind sustainable development.Have the paper of wood fibre simultaneously now, its tension and moistureproof and waterproof property are not very desirable.

The utility model inventor has proposed the design of the heterogeneous paper of a kind of NEW TYPE OF COMPOSITE promptly to the problems referred to above.

The utility model content

The utility model is to the disappearance of prior art existence, and its main purpose provides the heterogeneous paper of the better NEW TYPE OF COMPOSITE of a kind of performance.

For realizing above-mentioned purpose, the utility model adopts following technical scheme: the heterogeneous paper of a kind of NEW TYPE OF COMPOSITE is characterized in that: comprise

One basalis that constitutes by Cab-O-sil and high density polyethylene (HDPE);

One is compounded in the ethylene-acrylic acid modified copolymer layer of above-mentioned basalis upper surface;

And one be compounded in above-mentioned basalis lower surface the metallocene high-density polyethylene layer.

After the utility model adopts technique scheme; Its beneficial effect is: through ethylene-acrylic acid modified copolymer layer and metallocene high-density polyethylene layer being set both sides respectively up and down at said basalis; Make not only have moisture effect preferably, also had better pull resistance and stablized durable simultaneously.In addition; Because it need not to adopt string, has saved a large amount of timber resources, has excellent environment protecting; The Cab-O-sil that uses in the such scheme simultaneously; Can carry out recycling to some discarded industrial Cab-O-sil raw materials, it is turned waste into wealth, obtain the environment protecting that waste recovery utilizes again.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment:

Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment: be illustrated in figure 1 as the heterogeneous paper of a kind of NEW TYPE OF COMPOSITE of the utility model, it is characterized in that: comprise

One basalis 1 that constitutes by Cab-O-sil and high density polyethylene (HDPE);

One is compounded in the ethylene-acrylic acid modified copolymer layer 2 of above-mentioned basalis upper surface;

And one be compounded in above-mentioned basalis lower surface metallocene high-density polyethylene layer 3.

Focusing on of the utility model; Through ethylene-acrylic acid modified copolymer layer 2 and metallocene high-density polyethylene layer 3 being set both sides respectively about in the of 1 at said basalis; Make not only have moisture effect preferably, also had better pull resistance and stablized durable simultaneously.In addition,, saved a large amount of timber resources, had excellent environment protecting because it need not to adopt string., the Cab-O-sil that uses in the such scheme simultaneously can carry out recycling to some discarded industrial Cab-O-sil raw materials, and it is turned waste into wealth, and obtains the environment protecting that waste recovery utilizes again.

The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.

Claims (1)

1. the heterogeneous paper of NEW TYPE OF COMPOSITE is characterized in that: comprise

One basalis that constitutes by Cab-O-sil and high density polyethylene (HDPE);

One is compounded in the ethylene-acrylic acid modified copolymer layer of above-mentioned basalis upper surface;
