Abstract
The present disclosure provides a modified starch composition. The modified starch composition includes starch with a terminal siloxane having 100 parts by weight, water having 30-70 parts by weight, and a polyol having 5-35 parts by weight. The present disclosure also provides a starch composite foam material and method for preparing the same.
Claims11
A starch composite foam material, comprising:
- a modified starch composition having a weight ratio of 25-90 wt %, said modified starch composition comprising starch with a siloxane having 100 parts by weight, water having 30-70 parts by weight, and a polyol having 5-35 parts by weight, wherein the siloxane has 5-15 phr based on 100 phr of the starch;
- and
- a thermoplastic polymer having a weight ratio of 10-75 wt %.
A method for preparing a starch composite foam material, comprising:
- blending a modified starch composition having a weight ratio of 25-90 wt % and a thermoplastic polymer having a weight ratio of 10-75 wt % to form a starch glue said modified starch composition comprising starch with a siloxane having 100 parts by weight, water having 30-70 parts by weight, and a polyol having 5-35 parts by weight, wherein the siloxane has 5-15 phr based on 100 phr of the starch;
- and
- performing a foaming process on the starch glue to form a starch composite foam material.
