Compared with prior art, the invention has the advantages that：
Egg shell is the casing part of Passiflora edulis sims, and after the sarcocarp of Passiflora edulis sims is eaten, egg shell can be treated as eating
Product rubbish abandons, and egg shell contains the compositions such as cellulose, hemicellulose, lignin, and egg shell is pulverized and sieved by the present invention
After obtain egg shell powder, then with steam explosion machine, it is carried out with steam explosion and effectively eliminates half fiber in egg shell
Element obtains pretreatment egg shell powder, then carries out basification by sodium hydroxide solution, and basification effectively eliminates lignin
And micromolecular compound has obtained the alkalization egg shell powder that content of cellulose greatly improves, the mechanics of alkalization egg shell powder
Performance is fine, but its surface is rich in hydroxyl and poor in the interface compatibility between hydrophilic, and hydrophobic polrvinyl chloride,
Therefore the present invention carries out graft modification by TDI and processes obtaining modified egg shell powder to it, TDI and alkalization egg shell powder table
The hydroxyl reaction in face generates amine ester bond, and the hydrophilic on its surface is become hydrophobicity, improve itself and PVC base system it
Between interface compatibility so that modified egg shell powder can be uniformly dispersed in polrvinyl chloride and forms stronger interface cohesion,
Thus producing good potentiation and greatly improving the mechanical property of pvc sheathing compound.
