Abstract

PURPOSE: A method for manufacturing complex board by using granular carbon is provided to substitute conventional particle board or MDF, which is expensive as well as harmful to human due to residual formaldehyde that is used as an additive. The complex board, by using granular carbon, has properties such as deodorization, shielding the electromagnetic wave, and emitting anion. CONSTITUTION: The method comprises the steps of (i) granulating carbon to be 0.001-10 mm; (ii) controlling its weight to be about 150 kg/m¬3; (iii) roasting the carbon granule at 180°C for 2-3 min. The obtained carbon granule is mixed with wood chip in a ratio of 1:9 to 9:1, and additives such as urea resins, melamine resins, and phenolic resins are used.

Description

Manufacturing method of carbon granule composite board {AAAAA}

본 발명은 탄소과립체와 접착제를 이용한 복합 보드의 제조 방법에 관한 것으로, 기존 복합 보드(파티클보드, MDF 등)의 경우 목분과 접착제 또는 일부 비목재분을 혼합하여 제품화한 것으로 최근 들어 그 수요가 증가 추세에 있으나 원자재인 목재를 분쇄하여 혼입함으로 인해 가격이 고가이고 사용되는 접착제는 포름알데히드 잔류량의 환경적인 문제로 인해 작은양이 방출되는 접착제의 개발과 이에 따른 원가 상승 등으로 가구재로의 수요는 극히 한정되어 있다.The present invention relates to a method for manufacturing a composite board using carbon granules and adhesives. In the case of existing composite boards (particle boards, MDF, etc.), wood powder and adhesives or some non-wood flour are commercialized, and the demand thereof has recently increased. Although it is a trend, the price is high due to the crushing and mixing of raw material wood, and the demand for furniture materials is extremely high due to the development of adhesive that emits a small amount due to the environmental problems of formaldehyde residual amount and the resulting cost increase. It is limited.

또한, 주거 문화의 발달과 건축 기술의 발달 과정에서 가구나 실내 장식재의 기능은 자재 본질의 특성 외에 설치된 이후에도 주거 환경의 부분적 문제(예로써, 해충 등에 강하거나 전자파 차폐기능 등) 해소 기능을 추구하고 있는 실정이나 현재로써는 추상적 접근 방식이나 임의의 소재를 기존 제품에 부연시키는 정도(예로써, 방충제를 보드표면에 살포 처리하거나 전자파 차폐층을 보드 사이에 끼워 접합시키는 형태)이다.In addition, the function of furniture and upholstery in the development of residential culture and building technology is to pursue the function of resolving partial problems of the residential environment (for example, strong against pests or electromagnetic shielding, etc.) In practice, or at present, it is an abstract approach or the extent to which an arbitrary material is added to an existing product (for example, by spraying an insect repellent on the surface of the board or by bonding an electromagnetic shielding layer between the boards).

이러한 문제 해결을 위해 본 발명에서는 사용되는 목분 전량 또는 일부량을 숯이나 탄소과립체로 대체하여 기존의 접착제 등과 혼합하여 복합 보드를 제조하는 것을 특징으로 한다.In order to solve this problem, the present invention is characterized by manufacturing a composite board by mixing the whole or part of the wood powder used with charcoal or carbon granules and mixing with an existing adhesive.

이렇게 만들어진 탄소과립체 복합보드는 강력한 탈취력과 전자파 차폐능, 음이온 발생에 따른 실내 공기 정화 기능을 갖게 된다.The carbon granule composite board thus made has strong deodorizing ability, electromagnetic shielding ability, and indoor air purification function due to negative ion generation.

결과를 요약하면 본 발명에서 제조된 탄소과립체 복합보드에 사용되는 탄소과립체의 종류로는 활성탄이나, 삼나무, 참나무, 대나무류와 폐목등을 탄화조건하에서 만든 숯이 있으며 접착제류로는 요소수지계, 페놀수지계, 멜라민 수지계등 상온, 중온, 고온 등의 조건으로 사용되는 접착제 전종류가 가능하다.In summary, the carbon granules used in the carbon granular composite board manufactured in the present invention include charcoal made of activated carbon, cedar, oak, bamboo, and waste wood under carbonization conditions. All kinds of adhesives used under the conditions of normal temperature, medium temperature, high temperature, etc., phenol resin system, melamine resin system, etc. are possible.

탄소과립체의 입자크기는 O.OO1∼1O mm 바람직하게는 1OO∼1,OOO ㎛ 정도로 하고 접착제는 탄소과립체 부피(㎥)대비 150 kg 내외로 하여 경화 온도 및 시간은 180℃, 2∼3분내에서 이루어지도록 한 후 한국산업규격 KS F 3104에 준한 제품 규격 실험을 하였다.The particle size of the carbon granules is about 0.1 to 100 mm, preferably about 100 to 1,100 μm, and the adhesive is about 150 kg based on the volume of the carbon granules (m 3), and the curing temperature and time are 180 ° C. and 2-3 times. After it was done in minutes, the product standard was tested according to KS F 3104.
