Embodiment 1

[0030] see attached figure 1 , a kind of degradable film, its preparation method comprises the following steps:

[0031] S1: Mixing and extrusion plasticizing: According to the ratio of parts by weight, 15 parts of LDPE, 50 parts of LLDPE, 25 parts of HDPE, 8 parts of white mother, and 1 part of EPI are mixed uniformly and put into the extruder for plasticization and extrusion. . Specifically, the temperature of the extruder was adjusted to 225° C. and maintained for 20 minutes.

[0032] S2: extrusion casting: connecting, filtering, and casting processes are performed in sequence; wherein, the temperature of the connecting process is 250°C, the temperature of the filtration process is 290°C, and the temperature of the casting process is 275°C.

[0033] S3: Calendering and shaping; the temperature is set to 20°C for the rubber roller, 60°C for the embossed steel roller, and the pulling rate is 65m / min.

[0034] S4: Corona, trimming and winding: After corona treatment, trimmi...

Embodiment 2

[0036] A degradable film, the main difference from Example 1 is: 15 parts of LDPE, 50 parts of LLDPE, 25 parts of HDPE, 8 parts of white mother, and 2 parts of EPI (see Table 1 for details).

Embodiment 3

[0038] A degradable film, the main difference from Example 1 is: 15 parts of LDPE, 50 parts of LLDPE, 25 parts of HDPE, 8 parts of white mother, and 3 parts of EPI (see Table 1 for details).

Abstract

The invention discloses a degradable film and its preparation and application, and relates to the technical field of degradable materials. Among them, a degradable film, in parts by weight, is prepared from 10 to 20 parts of LDPE, 45 to 55 parts of LLDPE, 20 to 30 parts of HDPE, and 1 to 3 parts of a fast degrading agent. At the same time, the present invention also provides the application of a degradable film in sanitary products and medical products, and a preparation method of the degradable film. By adding a fast degrading agent to the raw materials, and reasonably controlling the ratio between LDPE, LLDPE, HDPE and the fast degrading agent, the degradable performance of the product can be improved, and the pollution caused by the waste of related products can be reduced, and it is environmentally friendly. advantages and help reduce waste of resources.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a degradable film and its preparation and application. Background technique [0002] With the development of society, people's requirements for product performance have extended from pure pursuit of performance to all aspects of products. Product packaging is an important link in the production and delivery process of products. At present, many products are packaged with plastic films, which are usually polyethylene, polypropylene, polyvinyl chloride and other materials; for sanitary products (such as sanitary napkins, Diapers, adult disposable incontinence products, pet urine pads, etc.) and medical products (such as protective clothing, isolation gown fabrics, surgical drapes, etc.), which are usually disposable items and are thrown away after use. After the traditional plastic film is discarded, it will not only pollute the environment, but also cause waste of re...
