Embodiment 1

[0023] Embodiment 1: Stir 100 grams of raw material soapstone in 1000 grams of deionized water to form a stable suspension with a concentration of 10% by mass; prepare 0.141 moles of organic cationic salt cetyltrimethylammonium chloride in deionized water into a 2% mass percent concentration solution. Stir the soapstone suspension at 90°C for 30 minutes at a stirring speed of 1000 rpm, then add the above-mentioned organic cation salt cetyltrimethylammonium chloride solution to the above-mentioned soapstone suspension, and react for 4 hours, Then filter. And the filtrate is washed several times with deionized water, and is detected by 0.1 mol / liter silver nitrate solution until there is no halogen ion in the washing liquid; the organic saponite after washing is dried and ground to obtain a particle size of 60 microns to 74 microns of organic saponite.

Abstract

The invention provides an intercalation polymerization poly lactic acid-organophilic saponite composite material and a method for preparing the same. The intercalation polymerization poly lactic acid-organophilic saponite composite material comprises the materials of lactic acid monomer, organophilic saponite, catalyst and solvent; the preparation method is as follows: the intercalation polymerization poly lactic acid-organophilic saponite composite material is obtained by polyreaction. Furthermore, the obtained intercalation polymerization poly lactic acid-organophilic saponite composite material is used as a material to make products needed. In the tercalation polymerization poly lactic acid-organophilic saponite composite material of the invention, the melting point is far higher than the pure poly lactic acid, which shows that the thermal stability of the intercalation polymerization poly lactic acid-organophilic saponite composite material; the application range of the material is further widened, so that the material is particularly applied to such fields as packaging materials, fibers and agricultural films, etc; moreover, the invention is simple in making process, thereby facilitating the industrialized production.

Description

[0001] The invention relates to the technical field of intercalation polymerization polylactic acid-organic saponite composite material and its preparation method using lactic acid monomer and organic saponite as raw materials, and is an intercalation polymerization polylactic acid-organic saponite composite material and its preparation method. Background technique [0002] With the development of science and society, people pay more and more attention to environmental and resource issues and become global issues. Traditional plastic materials using petroleum as raw materials are widely used, but it is difficult to recycle them after use. A large amount of plastic waste has caused the current serious "white pollution" problem due to its non-degradability. The emergence of degradable materials, especially the renewability of raw materials for degradable materials, provides an effective means to solve this problem. As a class of environmentally friendly functional materials wit...
