Abstract

본 발명은 폴리올레핀계 수지, 무기충전제 및 생선분해성 지방족 폴리에스테르계 수지를 함유하는 조성물을 용융성형한 원판쉬이트를 연신하여 얻어지는 것을 특징으로 하는 생붕괴성 통기성 쉬이트 및 그 제조방법을 제공하는 것이다. 보다 구체적으로 폴리올레핀계 수지 100 중량부에 무기충전제 20-250 중량부 및 탄소수가 12개 이하인 지방족계 디카르본산 또는 그의 산무수물과 탄소수가 12개 이하인 다가알콜과의 통상의 축중합반응으로 얻어지는 지방족 폴리에스테르계 1.5배로 연신하여 얻어지는 것을 특징으로 하는 생붕괴성 통기성 쉬이트 및 그 제조방법을 제공하는 것이다.The present invention provides a biodegradable breathable sheet and a method for producing the same, which are obtained by stretching an original sheet melt-molded with a composition containing a polyolefin resin, an inorganic filler and a fish-decomposable aliphatic polyester resin. . More specifically, aliphatic obtained by ordinary condensation polymerization of 20-250 parts by weight of inorganic filler with 100 parts by weight of polyolefin resin and aliphatic dicarboxylic acid having 12 or less carbon atoms or its acid anhydride and polyhydric alcohol having 12 or less carbon atoms The present invention provides a biodegradable breathable sheet and a method for producing the same, which are obtained by stretching at a polyester-based 1.5 times.

또한 본 발명은 폴리올레핀계 수지 100 중량부에 무기충전제 20-250 중량부, 지방족 폴리에스테르계 수지 5-200 중량부 및 광분해촉진제 0.005-5 중량부를 함유하는 조성물을 용융 성형한 원판쉬이트를, 적어도 면적연신배율 1.5배로 연신하여 얻어지는 것을 특징으로 하는 생/광붕괴성 통기성 쉬이트 및 그 제조방법을 제공하는 것도 포함된다.In addition, the present invention is at least a disc sheet melt-molded a composition containing 20-250 parts by weight of inorganic filler, 5-200 parts by weight of aliphatic polyester resin and 0.005-5 parts by weight of photodegradation accelerator to 100 parts by weight of polyolefin resin. It also includes providing a bio / photodegradable breathable sheet and a method for producing the same, which are obtained by stretching at an area draw ratio of 1.5 times.

본 발명에 의하면 외관이 양호하고 강도가 우수하며 적정 투습성을 가질뿐 아니라 사용 후 미생물에 붕괴되거나 동시에 빛에 의해서도 붕괴될 수 있는 특성을 갖는 통기성 쉬이트를 얻게 된다.According to the present invention, a breathable sheet having a good appearance, excellent strength, adequate moisture permeability, and having the property of being decomposed by microorganisms after use or at the same time can be decomposed by light is obtained.
