Field of the Invention The present invention relates to a manufacturing method of a heat insulating material, a manufacturing method using the same,

본 발명은 단열재의 제조 장치 및 이를 이용한 제조방법 그리고 단열재에 관한 것으로, 더욱 상세하게는 건축물에 설치되어 단열 성능을 발휘할 수 있는 단열재의 제조 장치 및 이를 이용한 제조방법 그리고 단열재에 관한 것이다.The present invention relates to an apparatus for manufacturing a heat insulating material, a manufacturing method using the same, and a heat insulating material, and more particularly, to a heat insulating material manufacturing apparatus installed in a building to exhibit heat insulating performance, a manufacturing method using the same, and a heat insulating material.

일반적으로 스티로폼(영어: styrofoam) 또는 스티로폴(독일어: Styropor)은 발포폴리스티렌이라는 플라스틱의 상표명이다. In general, styrofoam (styrofoam) or Styropor (German: Styropor) is a brand name of plastic called expanded polystyrene.

폴리스타이렌을 발포제(發泡劑)의 작용으로 팽창시킨 것으로 거품폴리스티렌·스티로폼(styrofoam)·발포스티렌, 스티로폴 등 여러 이름으로 불리며, 영문 머리글자를 따서 EPS로 약칭하기도 한다. 희고 가벼우며, 내수성, 단열성, 방음성, 완충성 등이 우수하여 널리 사용된다. Polystyrene is expanded by the action of foaming agent. It is called foaming polystyrene, styrofoam, foamed styrene, styropol, etc. It is abbreviated as EPS after initials in English. It is white and light, and it is widely used because it is excellent in water resistance, heat insulation, soundproofness and buffering properties.

An apparatus for manufacturing a heat insulating material according to the present invention comprises a mixer (2) for mixing a foamable resin with a vermiculite (vermiculite) or pearlite foam powder; A blender (4) for mixing the mixture obtained in the mixer (2) with a water-soluble adhesive and a flame retardant; A molding machine (6) for spreading the flame-retardant mixture obtained in the blender (4) so as to have a rectangular parallelepiped shape while being flat; A blow dryer (8) for heating the flat product obtained by the molding machine (6) by heating the microwave to expand it; A compression furnace (10) for compressing and molding the foamed material after it is transferred; And a cutting device (12) for cutting the compression molded product according to the standard.
