NON-ASBESTOS INSULATION BOARD WITH EXCELLENT MECHANICAL STRENGTH AND HEAT RESISTANCE AND MANUFACTURING METHOD THEREOF
The present invention relates to a non-asbestos insulation board with excellent mechanical strength and heat resistance and a manufacturing method thereof. The non-asbestos insulation board comprises 100 parts by weight of a reinforcement material containing mineral fibers, 70 to 150 parts by weight of a binding material, and 50 to 80 parts by weight of a filling material. The method includes: a material mixing step of mixing the reinforcement material containing mineral fibers, the binding material and the filling material; a first material mixing step of mixing the mixture mixed through the material mixing step at a speed of 1000 to 2000 rpm for two to five minutes; a second material mixing step of mixing 100 parts by weight of the mixture produced through the first material mixing step with 60 to 100 parts by weight of water and then mixing the mixture at a speed of 500 to 1500 rpm for two to five minutes; a compressive molding step of compressively molding the mixture produced through the second material mixing step at a pressure of 180 to 250 kgf/cm2; a curing step of the molded material produced through the compressive molding step at a humidity of 70 to 90% and a temperature of 30 to 60℃ for 24 to 48 hours; and a polishing step of polishing the molded material cured through the curing step. The non-asbestos insulation board manufactured with the components and the manufacturing method can improve a mechanical property by suppressing the inclination of materials due to mineral fibers contained as a reinforcement material as well as can have excellent high-temperature heat resistance and can have electrical insulation and thermal insulation due to aerogel or glass bubbles contained as filling materials.
본 발명은 기계적 강도와 내열성능이 우수한 비석면 단열보드 및 그 제조방법에 관한 것으로, 광물섬유가 함유된 보강재 100 중량부, 결합재 70 내지 150 중량부 및 충전재 50 내지 80 중량부로 이루어지며, 광물섬유가 함유된 보강재, 결합재 및 충전재를 배합하는 원료배합단계, 상기 원료배합단계를 통해 배합된 배합물을 1000 내지 2000rpm의 속도로 2 내지 5분 동안 혼합하는 제1원료혼합단계, 상기 제1원료혼합단계를 통해 제조된 혼합물 100 중량부에 물 60 내지 100 중량부를 혼합하고 500 내지 1500rpm의 속도로 2 내지 5분 동안 혼합하는 제2원료혼합단계, 상기 제2원료혼합단계를 통해 제조된 혼합물을 180 내지 250kgf/cm2의 압력으로 압축성형하는 압축성형단계, 상기 압축성형단계를 통해 제조된 성형물을 70 내지 90%의 습도와 30 내지 60℃의 온도에서 24 내지 48시간 동안 양생하는 양생단계 및 상기 양생단계를 통해 양생된 성형물을 연마하는 연마단계를 통해 제조된다. 상기의 성분 및 제조방법을 통해 제조되는 비석면 단열보드는 보강재로 광물섬유가 함유되어 원료의 쏠림현상 억제로 인해 기계적 물성이 향상될 뿐만 아니라, 고온 내열성능이 우수하며 충전재로 에어로겔 또는 글라스 버블이 함유되어 절연성 및 단열성이 우수하다.
