Problems solved by technology

[0003] The purpose of the present invention is to provide a method for preparing a composite degradable film, which can solve the problem that the existing film is easily damaged during use, and the film degradation rate is slow. Impurities, it is easy to cause a lot of small bumps in the film after the production is completed, which makes the quality of the film poor. This is mainly because the raw material of the film is not thoroughly ground before processing, and it is easy to bring in particles, and it is made of degradable materials. When manufacturing thin films, it is difficult to clean up impurities in raw materials

Embodiment Construction

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] see Figure 1-6 Shown, a kind of preparation method of composite degradable film, this degradable film comprises and is made up of protective layer, adhesive layer and degradable layer from top to bottom;

[0034] The protective layer is prepared from the following raw materials in parts by weight: 10-15 parts of modified chitosan powder, 15-20 parts of sodium carboxymethylcellulose powder, 10-15 parts of sodium trimetaphosphate, sugar alcohol plasticizer 5-10 copies;

[0035] The adhesive layer is prepared from th...

Abstract

The invention discloses a preparation method of a composite degradable film. The degradable film comprises a protective layer, a bonding layer and a degradation layer from top to bottom, wherein a grinding device comprises a machine shell; a transmission mechanism is installed on the machine shell. A heating mechanism is arranged in the machine shell. The heating mechanism is connected with the transmission mechanism, the bottom of the transmission mechanism is in transmission connection with a driven mechanism, the driven mechanism is connected with a grinding mechanism, an opening and closing mechanism matched with the transmission mechanism is arranged in the machine shell, and one side of the opening and closing mechanism is connected with a liquid outlet pipe. An enough heating spacecan be provided for the heating mechanism through the arranged upper cavity, and an enough space can be provided for transmission of the transmission mechanism and the driven mechanism through the arranged lower cavity; opening and closing of the system can be achieved through rotation of the transmission mechanism through the arranged opening and closing mechanism, and therefore, the amount of amixed solution in the storage box is controlled.

Description

technical field [0001] The invention belongs to the technical field of film preparation, and in particular relates to a preparation method of a composite degradable film. Background technique [0002] The existing film is easy to be damaged when used, and the degradation rate of the film is slow. During the production process of the film, due to some particles and impurities contained in the film, it is easy to cause a lot of small bumps on the film after the production is completed, which makes the film The use quality of the film is poor, mainly because the film raw material is not thoroughly ground before processing, it is easy to bring in particles, and when the film is made of degradable materials, it is difficult to clean the impurities in the raw material. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a composite degradable film, which can solve the problem that the existing film is easily damaged during...
