Embodiment Construction

[0016] Non-limiting examples of the present invention are as follows:

[0017] A fully degradable film with insect repellent effect, prepared from the following component raw materials in weight (kg):

[0018] β-cyclodextrin 10, corn starch 50, medical stone powder 4, polyvinyl alcohol 25, polyethylene glycol 3, glycerin 20, isopropyl myristate 4, cottonseed oil 1.5, tetraethyl orthosilicate 4, camphor Oil 1.5, Tween-80 1.5.

[0019] The preparation method of the fully degradable film with deworming effect comprises the following steps:

[0020] (1) Mix β-cyclodextrin, cornstarch and medical stone powder, then add absolute ethanol at a solid-to-liquid weight ratio of 1:1, then add camphor oil for ultrasonic treatment for 15 minutes, filter and dry to obtain a mixed powder;

[0021] (2) Add the mixed powder and polyethylene glycol obtained in (1) into the mixed solution of an appropriate amount of ethanol / water / ammonia and disperse it ultrasonically for 15 minutes to obtain a...

Abstract

The invention discloses a full degradable film with insect repellent efficacy which is characterized by comprising the following raw material by weight: 8-12 parts of beta cyclodextrin, 40-60 parts of corn starch, 3-5 parts of medical stone powder, 20-30 parts of polyvinyl alcohol, 2-4 parts of polyethylene glycol (peg), 15-25 parts of glycerin, 3-5 parts of isopropyl myristate, 1-2 parts of cottonseed oil, 3-6 parts of ethyl orthosilicate, 1-2 parts of camphorated oil and 1-2 parts of tween-80. The full degradable film with insect repellent efficacy has good insect repellent effect, good mechanical properties and resistance to water, and good degradation performance, and is low in price, green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of film materials, in particular to a fully degradable film with insect repelling effect and a preparation method thereof. Background technique [0002] In recent years, the call for improving the ecological environment has become increasingly louder. As a large packaging country, my country uses a huge amount of plastic packaging products. Waste plastics are difficult to degrade and remain in the environment to form "white pollution", which seriously threatens the living environment of human beings. Therefore, it has become an inevitable trend to develop environmentally friendly, non-toxic, non-polluting fully biodegradable films to replace traditional packaging films. [0003] PVA is a kind of high molecular polymer with a wide range of uses. The molecule contains a large number of hydroxyl groups. There is a strong attraction between adjacent molecules, and it has good barrier properties, strong adhesion, flexibil...
