| 中文摘要: |
| 以竹材化学浆和针叶木化学浆为原料制备纸浆模塑包装材料，分别将无氟有机硅乳液（En和B9）及阳离子淀粉（CS）复配改性的无氟有机硅乳液（CE3/1-B9）喷涂于纸浆模塑包装材料表面，并对喷涂前后纸浆模塑包装材料的防水防油及耐温性能进行评价。结果表明，未改性的En和B9均不能使纸浆模塑包装材料同时具有较好的防水防油及耐温性能；当有机硅乳液总用量为5 g/m2时，喷涂CE3/1-B9的纸浆模塑包装材料水接触角在5 min内仅降低7°，吸水性（Cobb30值）由508 g/m2降至3 g/m2，防油等级（Kit值）为8~9，耐温性能大幅提升；喷涂CE3/1-B9纸浆模塑餐碗的水接触角在5 min内仅降低4°~5°，Cobb30值为5~10 g/m2，Kit值为6~8，且具备较好的耐温性能。 |
| Abstract: |
| In this paper， the molded pulp packaging material was made from bamboo and softwood chemical pulp， and the organic silicon emulsion （En and B9） and cationic starch modified organic silicone emulsion （CE3/1-B9） were sprayed on the surface of the molded pulp packaging material. The water and oil resistance and temperature resistance of the molded pulp packaging materials before and after treatment were evaluated. The results showed that neither of the unmodified En and B9 endowed molded pulp packaging materials with good water and oil resistance and temperature resistance at the same time. When the total amount of organic silicone emulsion was 5 g/m2， the water contact angle of the laboratory-made molded pulp packaging material after spraying CE3/1-B9 decreased by merely 7° within 5 min， the water absorption （Cobb30 value） decreased from 508 g/m2 to 3 g/m2， and the oil resistance grade （Kit value） was 8~9， and the temperature resistance was greatly improved. It was found that the water contact angle of molded pulp dining bowl after spraying CE3/1-B9 decreased by 4°~5°within 5 min， the Cobb30 value was 5~10 g/m2， and the Kit value was 6~8. In addition， it had great temperature resistance. |
