Description
본 발명은 합성 목재 및 그 제조 방법에 관한 것으로서, 보다 상세하게는 목재료를 모재로 하는 합성 목재 및 그 제조 방법에 관한 것이다.The present invention relates to synthetic wood and a method for manufacturing the same, and more specifically, to a synthetic wood using wood as a base material and a method for manufacturing the same.
목재는 특유의 자연미를 지니고 있어 건축물의 내/외장재, 데크/펜스 등과 같은 각종 설치물, 각종 가구, 그 외 다양한 산업/가정용 제품의 재료로 널리 활용되는 소재 중 하나이다. Wood has a unique natural beauty and is one of the materials widely used as a material for interior/exterior materials of buildings, various installations such as decks/fences, various furniture, and various industrial/household products.
그러나, 이와 같은 목재는 비교적 고중량이고, 그 규격과 형상 등이 한정되어 있어 가공/시공 등이 어려우며, 원목 생산량에 한계가 있어 비교적 높은 가격대를 나타내는 등 여러 문제점들을 지니고 있다. However, such wood is relatively heavy and has limited dimensions and shapes, making processing/construction difficult, and has a relatively high price due to limitations in raw wood production, and has several problems.
이와 같은 문제점들을 해결하기 위하여, 원목에 타 재료들을 가미한 다양한 합성 목재(Wood Plastic Composite, WPC) 제품들이 출시되고 있으며, 이에 대한 일 예로 선행하는 대한민국 등록 특허 제 10-2003749 호에는 접착력 향상, 기계적 특성 강화된 미끄럼방지 성능이 향상된 합성목재 및 그 제조방법이 개시되어 있다.In order to solve these problems, various wood plastic composite (WPC) products are being released by adding other materials to raw wood. As an example of this, the preceding Korean Patent No. 10-2003749 has improved adhesion and mechanical properties. A synthetic wood with improved anti-slip performance and a manufacturing method thereof are disclosed.
또한, 상기 선행문헌에는 열경화성 프라이머층, 미끄럼방지 코팅 등이 적용된 합성 목재에 관한 사항이 개시되어 있고, 이에 따르는 경우 미끄럼 방지 효과 및 기계적 물성 증가 등이 기대될 수 있다.In addition, the above prior literature discloses information on synthetic wood to which a thermosetting primer layer, anti-slip coating, etc. are applied, and if this is followed, an anti-slip effect and an increase in mechanical properties can be expected.
이때, 목재의 경우 난연성이 취약한 소재 중 하나로, 별도의 난연 처리가 필수적으로 수반되어야 하고 이에 관해 엄격한 규제들이 적용되나, 상기 선행문헌에는 이와 같은 목재의 난연성 증진에 관한 사항이 전혀 개시되어 있지 않아, 이를 해결하기 위한 별도의 방안이 모색될 필요가 있다. At this time, wood is one of the materials with weak flame retardancy, so separate flame retardant treatment is essential and strict regulations are applied in this regard. However, the prior literature does not disclose anything about improving the flame retardancy of wood. A separate plan needs to be sought to solve this.
상술한 과제 해결의 일환으로, 본 발명은 난연성이 증진된 합성 목재 및 그 제조 방법을 제공하고자 하는 것을 그 목적으로 한다.As part of solving the above-described problems, the purpose of the present invention is to provide synthetic wood with improved flame retardancy and a method for manufacturing the same.

또한, 상기 합성 목재는, 상기 목분 100 중량부에 대하여 PE 10~50 중량부, PP 10~25 중량부, 윤활제 1~10 중량부, 커플링제 2~15 중량부, 안료 1~15 중량부, 산화 방지제 0.1~3 중량부 및 UV 차단제 0.1~2 중량부를 포함하는 군에서 선택되는 적어도 하나의 혼합 재료를 포함하는 것을 특징으로 한다.In addition, the synthetic wood contains 10 to 50 parts by weight of PE, 10 to 25 parts by weight of PP, 1 to 10 parts by weight of lubricant, 2 to 15 parts by weight of coupling agent, and 1 to 15 parts by weight of pigment, based on 100 parts by weight of wood flour. It is characterized in that it contains at least one mixed material selected from the group containing 0.1 to 3 parts by weight of an antioxidant and 0.1 to 2 parts by weight of a UV blocker.
본 발명에 의한 합성 목재 및 그 제조 방법에 따르면, 모재인 목분과의 혼합성이 매우 높고 친환경 재료이며 난연성이 우수한 재료인 탄닌산이 합성 목재의 재료로 활용될 수 있으며, 이를 통해 난연성이 우수하면서도 높은 제조 용이성과 친환경성을 지닌 합성 목재가 제공될 수 있게 된다. According to the synthetic wood and its manufacturing method according to the present invention, tannic acid, which has very high miscibility with wood flour as the base material, is an eco-friendly material, and has excellent flame retardancy, can be used as a material for synthetic wood, and through this, it has excellent flame retardancy and high flame retardancy. Synthetic wood that is easy to manufacture and eco-friendly can be provided.
또한, 상기 탄닌산과 목분이 상호 혼합된 상태로 상기 합성 목재가 제조될 수 있으며, 이에 따라 절단면 등 해당 합성 목재의 내부에도 탄닌산과 같은 난연성 증진/부여 물질들이 고루 분포할 수 있게 되어, 이를 통해 난연재 코팅 등 타 방식들 대비 월등히 우수한 난연성을 지닌 합성 목재가 제공될 수 있게 된다. In addition, the synthetic wood can be manufactured in a state in which the tannic acid and wood powder are mixed together, and as a result, flame retardant enhancing/imparting substances such as tannic acid can be evenly distributed inside the synthetic wood, such as on the cut surface, thereby making the flame retardant material.

이때, 본 비교예에 활용된 재료들의 중량 총합은 실시예 1과 동일하다.At this time, the total weight of the materials used in this comparative example is the same as Example 1.
[시험예 1][Test Example 1]
상술한 각 실시예 및 비교예에 의한 합성 목재의 난연성 비교를 위하여 본 발명의 발명자들은 한국 건설 생활 환경 시험 연구원에 KS 난연성 시험을 의뢰하였으며(KS F 3230:2020), 그 결과는 하기 표 1의 내용과 같다.In order to compare the flame retardancy of synthetic wood according to each of the above-described examples and comparative examples, the inventors of the present invention requested a KS flame retardancy test from the Korea Construction and Living Environment Testing Institute (KS F 3230:2020), and the results are shown in Table 1 below. Same as the content.
더 상세하게는, 본 시험예에서는 KS F 3230:2020 시험법에 의거하여 각 실시예 및 비교예에 의한 합성 목재에 대하여 동일 온도 및 동일 세기의 화염을 동일 시간 동안 접염시키는 과정이 진행되었다.More specifically, in this test example, the process of contacting the synthetic wood of each example and comparative example with a flame of the same temperature and intensity for the same time was conducted according to the KS F 3230:2020 test method.
그리고, 상기 표 1을 살펴보면 실시예 1, 실시예 2 및 비교예 1 모두 방염성 관련 KS F 3230:2020 시험의 합격 기준인 탄화 길이 20cm 이하, 연소 시간 10초 이하를 만족하는 것으로 확인되었으나, 상호간 다음과 같은 현저한 결과 차이가 나타나는 것으로 확인되었다. In addition, looking at Table 1 above, it was confirmed that Example 1, Example 2, and Comparative Example 1 all satisfied the passing criteria of the flame retardancy-related KS F 3230:2020 test: carbonization length of 20 cm or less and combustion time of 10 seconds or less. It was confirmed that there was a significant difference in results.
먼저, 실시예 1에 의한 합성 목재가 비교예 1 대비 11% 수준으로 짧은 1초라는 연소시간을 기록하는 것으로 확인되었다.First, it was confirmed that the synthetic wood according to Example 1 recorded a combustion time of 1 second, which is 11% of that of Comparative Example 1.
또한, 실시예 2에 의한 합성 목재가 비교예 1 대비 22% 수준으로 짧은 2초라는 연소시간을 기록하는 것으로 확인되었으며, 이는 실시예 1 대비 2배 가량 긴 시간에 해당된다.In addition, it was confirmed that the synthetic wood according to Example 2 recorded a combustion time of 2 seconds, which is 22% shorter than that of Comparative Example 1, which corresponds to a time approximately twice as long as that of Example 1.
이러한 결과들을 종합하면 합성 목재에 탄닌산이 더 포함됨으로써, 합성 목재의 난연성이 더욱 증진되는 것을 알 수 있다. Taking these results together, it can be seen that the flame retardancy of synthetic wood is further improved by the inclusion of more tannic acid in synthetic wood.
또한, 실시예 1과 실시예 2를 상호 비교하면, 탄닌산의 비율이 높아질수록 그 난연성 또한 비례하여 증가하는 것으로 확인되나, 이러한 탄닌산의 비율이 증가할수록 합성 목재의 기계적 강도가 저하되는 점 등을 감안한다면 그 상한은 목분 100 중량부에 대해 200 중량부인 것이 바람직한 것으로 확인되었다. In addition, when comparing Example 1 and Example 2, it was confirmed that the flame retardancy also increased proportionally as the ratio of tannic acid increased, but considering that the mechanical strength of synthetic wood decreased as the ratio of tannic acid increased. In this case, it was confirmed that the upper limit is preferably 200 parts by weight for 100 parts by weight of wood flour.
또한, 본 발명의 실시예들과 같이, 모재인 목분과 난연성을 증진/부여하는 탄닌산의 혼합물이 합성 목재로 활용됨에 따라, 난연재 코팅 등 다른 방식들에 비해 내부 절단면 등에도 충분한 난연성이 확보될 수 있게 된다.In addition, as in the embodiments of the present invention, as a mixture of wood flour, which is the base material, and tannic acid, which enhances/gives flame retardancy, is used as synthetic wood, sufficient flame retardancy can be secured on internal cut surfaces, etc., compared to other methods such as flame retardant coating. There will be.
이상과 같이 본 발명은 합성 목재 및 그 제조 방법을 제공하고자 하는 것을 주요한 기술적 사상으로 하고 있으며, 도면을 참고하여 상술한 실시 예는 단지 하나의 실시 예에 불과하고, 본 발명의 권리 범위는 특허 청구범위 뿐만이 아닌, 다양하게 존재할 수 있는 균등한 실시 예에도 미친다 할 것이다.As described above, the main technical idea of the present invention is to provide synthetic wood and a manufacturing method thereof, and the embodiment described above with reference to the drawings is only one embodiment, and the scope of the present invention is defined by the patent claims. This applies not only to the scope but also to various equivalent embodiments that may exist.
