Abstract

The invention relates to a kind of low-temp. water instantable manometre compound plastic film, which can be quick dissolved in warm water at temp. 0 deg.C or more than 0 deg.C and prepn. method. It is composed by following weight portions of raw materials: paval 100, softex kw organic imvite 0-10, defoamer 0.2-2, flatting agent 0.2-2, water 1000-6000, plasticizer 0-30. Degree of said poval is 2400-2500, the prepn. method is as following: to mix organic imvite, poval and water in ratio and to stir uniform, the proceed microwave radiation in proper time, then cooling to room temp. to add defoamer, flatting agent and appropriate amount of plsticizer, which are mixed uniformly to produce said film.

Description

technical field [0001] The invention relates to a low-temperature water instant nano-composite plastic film and a preparation method thereof. Background technique [0002] With the continuous progress of society, the use of polymer materials in people's daily life is increasing, which brings convenience to people's life and improves people's quality of life. However, in the process of large-scale production and use , A large amount of waste is produced. If these wastes are thrown into the nature without any treatment, they will form the so-called "white pollution", cause serious problems to the society, and become a pollution source that has a huge destructive effect on the human ecological environment. . Although plastic waste can be recycled and recycled, in many cases, it is very difficult to recycle waste polymers, and the recycling cost of some polymers is even much higher than the manufacturing cost of polymers. Therefore, the new water-soluble and pollution-free Gre...
