Abstract
본 발명은, 종이 입자와 수지성 용액을 혼합하여 준비하는 단계; 및 종이 입자와 상기 수지성 용액이 혼합되어 종이 입자 사이에 수지성 용액이 믹싱되는 단계를 포함하는 기술적 사상을 개시한다.

Description
본 발명은 종이 입자에 베리어 코팅을 제공하여 습기 또는 수분에 강한 종이를 형성하도록 하는 베리어 코팅을 구비한 강습 페이퍼지에 관한 기술분야이다.The present invention relates to the technical field of training paper with a barrier coating that provides a barrier coating to paper particles to form paper that is resistant to moisture or moisture.
"지방산을 압착 가열 기상 그라프팅 처리한 소수성 종이 및 그 제조방법(출원번호 제10-2020-0093949호, 특허문헌 1이라 한다.)"가 존재한다. “Hydrophobic paper obtained by compressing, heating, and vapor phase grafting of fatty acids and its manufacturing method (Application No. 10-2020-0093949, referred to as Patent Document 1)” exists.
특허문헌 1은, 압착 가열 가스 그라프팅 소수화 처리 설비를 이용한 소수성 종이 제조방법은 비통기성 드라이어 벨트가 구비된 압착 가열 가스 그라프팅 소수화 처리 설비를 이용하므로 염화지방산과 종이 수산기의 반응 시 발생하는 염산의 소산을 막아 지방산과 종이 수산기가 에스테르화 반응을 일으키도록 염산을 촉매로써 사용하는 특징이다. Patent Document 1 states that the method for producing hydrophobic paper using a press heating gas grafting hydrophobization treatment facility uses a press heating gas grafting hydrophobization treatment facility equipped with a non-breathable dryer belt, so that the hydrochloric acid generated during the reaction between chlorinated fatty acids and paper hydroxyl groups is removed. It is characterized by using hydrochloric acid as a catalyst to block dissipation and cause an esterification reaction between fatty acids and paper hydroxyl groups.
특허문헌1의 경우, 값비싼 염화지방산의 일부를 저렴한 일반 지방산으로 대체한 혼합 소수화제를 사용하므로 종래의 염화지방산만을 소수화제로 사용한 소수화 종이의 제조방법에 대비하여 동일한 품질의 소수화 종이를 더 저렴한 제조비용으로 제조할 수 있는 장점이 있다.In the case of Patent Document 1, a mixed hydrophobizer is used in which some of the expensive chlorinated fatty acids are replaced with inexpensive general fatty acids, so compared to the conventional method of manufacturing hydrophobized paper using only chlorinated fatty acids as the hydrophobizer, the same quality of hydrophobized paper is cheaper. It has the advantage of being able to be manufactured at low manufacturing costs.
또한 특허문헌 1에 따르면, 압착 가열 가스 그라프팅 소수화 처리 설비를 이용한 소수성 종이 제조방법은 종래의 염화지방산과 가스 그라프팅 소수화 처리 설비를 이용한 소수화 종이의 제조방법에 대비하여 반응시 발생하는 염산과 같은 강산을 재활용하므로 강산의 처리비용이 절감되는 효과가 있다In addition, according to Patent Document 1, the method of producing hydrophobic paper using a compressed heating gas grafting hydrophobization treatment facility is different from the method of producing hydrophobization paper using a conventional chlorinated fatty acid and gas grafting hydrophobization treatment facility, such as hydrochloric acid generated during reaction. By recycling strong acids, the cost of processing strong acids is reduced.
