상기 실시예 1 내지 9 및 비교예 1 내지 3에서 제조된 인조잔디 충진재의 압출 작업성, 마모율 및 생분해율을 하기 측정방법을 통해 측정하였고, 이에 대한 결과를 하기 표 2에 나타내었다.The extrusion workability, abrasion rate, and biodegradation rate of the artificial turf filler prepared in Examples 1 to 9 and Comparative Examples 1 to 3 were measured through the following measurement methods, and the results are shown in Table 2 below.
[측정방법][measurement method]
생분해율 및 마모율 : KS F 3888-1 : 2018 규격에 따라 Uniform 내마모 설비에 충진재가 첨가된 인조잔디 완제품을 넣고 2,000회 가동하여 마모시킨 후, ASMT D 5511 규격으로 90일 기준에 따라 테스트함Biodegradation rate and abrasion rate: According to KS F 3888-1: 2018 standard, put the finished artificial turf product with filler added into a uniform wear-resistant facility, operate it 2,000 times and wear it out, and then test according to the ASMT D 5511 standard for 90 days.
[측정방법][measurement method]
압출 작업성 : 입자 크기 균일할 경우 양호, 입자 크기 불균일할 경우 불량으로 평가함Extrusion workability: It is evaluated as good when the particle size is uniform, and evaluated as poor when the particle size is non-uniform.
상기 표 2를 참조하면, 생분해제 및 아크릴 실리콘 공중합체를 1중량% 및 0.1중량% 포함하는 경우(실시예 1)는 압출 작업성 및 마모율이 우수하였으며, 생분해율이 마모 전 보다 마모 후 약 31배 증가한 3.1% 인 것을 확인할 수 있다.Referring to Table 2, in the case of containing 1% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 1), the extrusion workability and wear rate were excellent, and the biodegradation rate was about 31 after wear than before wear. It can be seen that it is a double increase of 3.1%.
또한, 생분해제 및 아크릴 실리콘 공중합체를 2중량% 및 0.1중량% 포함하는 경우(실시예 2)는 마모율이 우수하였고, 생분해율이 마모 전 보다 마모 후 약 32배 증가한 3.2% 인 것을 확인할 수 있다.In addition, in the case of containing 2% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 2), the wear rate was excellent, and it can be seen that the biodegradation rate is 3.2%, which is about 32 times higher after wear than before wear. .
또한, 생분해제 및 아크릴 실리콘 공중합체를 0.5중량% 및 0.1중량% 포함하는 경우(실시예 3)는 압출 작업성 및 마모율이 우수하였으나, 생분해율이 생분해제를 1중량% 포함하는 경우(실시예 1)보다 다소 낮은 것을 확인할 수 있다.In addition, in the case of containing 0.5% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 3), the extrusion workability and wear rate were excellent, but the biodegradation rate was 1% by weight of the biodegradable agent (Example 3). 1) can be found to be slightly lower.
또한, 생분해제 및 아크릴 실리콘 공중합체를 1중량% 및 0.5중량% 포함하는 경우(실시예 4)는 압출 작업성이 아크릴 실리콘 공중합체를 0.1중량% 포함하는 경우(실시예 1)보다 좋지 않은 것을 확인할 수 있다.In addition, in the case of containing 1% by weight and 0.5% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 4), the extrusion workability is not as good as in the case of containing 0.1% by weight of the acrylic silicone copolymer (Example 1). You can check.
또한, 생분해제 및 아크릴 실리콘 공중합체를 0.1중량% 및 0.1중량% 포함하는 경우(실시예 5)는 생분해율이 생분해제를 1중량% 포함하는 경우(실시예 1)보다 다소 낮은 것은 확인할 수 있다.In addition, in the case of containing 0.1% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 5), it can be confirmed that the biodegradation rate is slightly lower than that in the case of containing 1% by weight of the biodegradable agent (Example 1). .
생분해제 및 아크릴 실리콘 공중합체를 5중량% 및 0.1중량% 포함하는 경우(실시예 6)는 생분해율이 마모 후 가장 우수하였으나, 첨가된 함량 대비 생분해율의 향상도가 미미한 것을 확인할 수 있다.In the case of containing 5% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 6), the biodegradation rate was the best after wear, but it can be seen that the improvement in the biodegradation rate compared to the added content is insignificant.
생분해제 및 아크릴 실리콘 공중합체를 0.05중량% 및 0.1중량% 포함하는 경우(실시예 7)는 생분해율이 생분해제를 1중량% 포함하는 경우(실시예 1)보다 매우 낮은 것은 확인할 수 있다.In the case of containing 0.05% by weight and 0.1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 7), it can be confirmed that the biodegradation rate is much lower than that of the case containing 1% by weight of the biodegradable agent (Example 1).
생분해제 및 아크릴 실리콘 공중합체를 1중량% 및 1중량% 포함하는 경우(실시예 8)은 압출 작업성이 아크릴 실리콘 공중합체를 0.1중량% 포함하는 경우(실시예 1)보다 좋지 않은 것을 확인할 수 있다.In the case of containing 1% by weight and 1% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 8), it can be seen that the extrusion workability is not as good as the case of containing 0.1% by weight of the acrylic silicone copolymer (Example 1). there is.
생분해제 및 아크릴 실리콘 공중합체를 1중량% 및 0.01중량% 포함하는 경우(실시예 9)는 마모율이 21.5%로 매우 높아 아크릴 실리콘 공중합체를 0.1중량% 포함하는 경우(실시예 1)보다 내마모성이 저하된 것을 확인할 수 있다.In the case of containing 1% by weight and 0.01% by weight of the biodegradable agent and the acrylic silicone copolymer (Example 9), the wear rate was very high at 21.5%, and the wear resistance was higher than that of the case containing 0.1% by weight of the acrylic silicone copolymer (Example 1). deterioration can be observed.
한편, 생분해를 포함하지 않는 경우(비교예 1)는 생분해가 진행되지 않았으며, 아크릴 실리콘 공중합체를 포함하지 않는 경우(비교예 2)는 모두 포함하는 경우(실시예 1)보다 마모율이 매우 높고, 마모 전 및 마모 후의 생분해율이 동일한 것을 확인할 수 있다.On the other hand, in the case of not including biodegradation (Comparative Example 1), biodegradation did not proceed, and in the case of not including acrylic silicone copolymer (Comparative Example 2), the wear rate was much higher than that of the case of including both (Example 1). , it can be confirmed that the biodegradation rates before and after abrasion are the same.
또한, 생분해 및 아크릴 실리콘 공중합체를 모두 포함하지 않는 경우(비교예 3)는 생분해가 진행되지 않고, 마모율 또한 매우 높은 것을 확인할 수 있다.In addition, in the case of not including both biodegradable and acrylic silicone copolymers (Comparative Example 3), it can be seen that biodegradation does not proceed and the wear rate is also very high.
