Description

도막재를 이용한 일체형 복합방수시트 및 그 제조방법{RECIPE OF COATING MATERIAL USING THE COMPLEX WATERPROOF SEAT AND THE SAME THEREOF MANUFACTURING METHOD}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an integrated composite waterproof sheet using a coating material,

본 발명은 방수용 도막재를 섬유질 시트로 형성된 보강재에 도포한 일체형 복합방수시트 및 그 제조방법에 관한 것으로서, 보다 상세하게는 역타설공법으로 구축되는 건축/토목 구조물의 역타설방수에 특히 적합하고, 방수성을 지닌 각각의 방수용 도막재를 섬유질 시트로 형성된 보강재 표면 및 이면측에 순차적으로 도포한 정형화된 복합방수시트와 건축/토목 구조물의 용도와 외부 환경적인 요소에 대응할 수 있는 방수용 도막재를 이용한 일체형 복합방수시트 및 그 제조방법에 관한 것이다.
The present invention relates to an integral composite waterproof sheet in which a waterproof coating material is applied to a reinforcing material formed of a fibrous sheet and a method of manufacturing the composite waterproof sheet. More particularly, the present invention relates to a composite waterproof sheet which is suitable for waterproofing a building / civil structure, Each waterproof coating material with waterproof property is applied to the surface of the stiffener made of fibrous sheet and the back side in order, and the composite waterproof sheet is used as an integral type using the waterproof coating material that can cope with the use of the building / A composite waterproof sheet and a method for manufacturing the same.

통상적으로 건축/토목구조물의 바닥, 외벽, 슬래브는 구조물의 용도와 외부 환경적인 요소 등 제반 사항을 고려하여 최적의 방수공법을 선택해 시공한다. 방수재로는 주로 방수시트와 도막방수재가 쓰이며, 경우에 따라서는 방수시트와 도막방수재가 혼용되기도 한다.Generally, the floor, outer wall, and slab of construction / civil structure should be constructed by choosing the most suitable waterproofing method considering various matters such as the use of the structure and external environment factors. The waterproofing material is mainly a waterproof sheet and a coating waterproofing material, and in some cases, a waterproof sheet and a coating waterproofing material are mixed.

방수시트는 시트재에 합성수지계, 아스팔트계 등의 방수재를 함침하거나 도포하여 건조시킨 것으로, 방수시공면에 접착제를 도포한 후 포설하여 접합하는 방식으로 방수한다.The waterproof sheet is waterproofed by impregnating or applying a waterproof material such as a synthetic resin or asphalt to the sheet material, and drying it by applying an adhesive to the waterproof surface and laying it.

도막방수는 1액 또는 2액형 도막방수재를 소정의 두께로 방수시공면에 도포하고 건조시켜 방수하는 것이고, 복합방수공법은 방수시공면에 도막방수재를 도포 및 건조시킨 후 그 상면에 방수시트를 포설하여 접착하는 방식으로 방수하는 것이다.The coating waterproofing method is to apply a one- or two-part coating film waterproofing material to a waterproof coating surface with a predetermined thickness, and to dry and waterproof the composite waterproofing method. In the composite waterproofing method, a waterproofing sheet is applied on a waterproof coating surface, So that it is waterproofed.

방수층의 두께가 균일하고 방수면의 평탄도가 양호해 방수품질을 유지할 수 있는 방수시트의 하단에 시공되는 도막방수층은 방수작업자의 숙련도에 따라 도막두께에 편차가 심해 안정된 방수품질을 얻기 곤란하다.It is difficult to obtain a stable waterproof quality due to a large variation in film thickness depending on the skill of a waterproof worker, which is applied to the bottom of the waterproof sheet, which is uniform in thickness of the waterproof layer and has a flatness of the waterproof surface.

이런 문제를 의식하여 제안된 것이 등록특허 제10-0580574호다. 이 선행기술은 도막방수층의 두께 균등화, 방수시트와 도막방수재간의 균일한 합착 및 일체화, 도막방수층의 품질관리 편의를 도모하기 위한 보강 도막형 시트재를 이용한 도막시트 일체형 건식화 복합 방수재에 관한 것인데, 방수액 흡수형 보강재의 표면 또는 양면에 단일 또는 조합형 도막방수재를 도포하여 도막방수층을 형성한 보강 도막시트; 방수액 흡수형 보강재의 표면 또는 양면에 도막방수층 형성용 도막보강재와 상기 도막보강재의 도막방수층 표면으로 압출하여 합친 방수시트재; 폴리에스테르계 장섬유 또는 단섬유를 니늘 펀칭, 열압착, 열처리 또는 유리섬유로 보강한 부직포 또는 폴리프로필렌계 직포; 시멘트 혼입 폴리머계, 수화응고형, 규산질계, 우레탄/타르 우레탄 고무계, FRP 중에서 선택된 2액형 반응 경화형 도막방수재 또는 아크릴 고무계, 클로로프로렌고무계, 아크릴 우레탄계, 아크릴수지계, 고무 아스팔트계에서 선택된 1액형 도막방수재 중의 적어도 어느 일종이 적층된 구조; 경질 / 연질의 염화비닐수지 시트, LLDPE, LLDPE + HDPE / LLDPE + LDPE로 이뤄지는 발포 또는 비발포 에틸렌계 시트, VA + LLDPE, HDPE, PE / EVA / VA 함량이 10~30중량%인 PE 폴리에틸렌 비닐 아세테이트(PEVA)로 구성된 EVA계 시트, EPM, EPDM, EPT를 단독 또는 LLDPE, LDPE, PE의 개질에 의한 가소화 합성수지 고무계 시트, 합성고무계 시트, 합성수지 APP, 합성고무 SBS 등의 폴리머로 개량된 아스팔트 시트, 합성고무를 이용한 고무화 아스팔트계 시트, 아스팔트 컴파운드가 적용된 시트 중에서 선택된 1종이다.It is a registered patent No. 10-0580574 in consideration of such a problem. This prior art relates to an integrated coating type sheet-type composite waterproofing material using a reinforcing film-like sheet material to equalize the thickness of the waterproof layer of the coating film, uniformly adhere and integrate the waterproof sheet and the coating material waterproofing material, A reinforcing coating film sheet on which a waterproofing layer is formed by applying a single or combination coating film waterproofing material on the surface or both surfaces of the waterproofing liquid absorbent stiffener; A waterproof sheet material which is extruded from the surface waterproof layer reinforcing material for forming a coating film waterproof layer and the surface of the coating film waterproof layer of the coating film reinforcing material, Nonwoven fabrics or polypropylene woven fabrics reinforced with polyester-based long-fiber or short-fiber by means of needle punching, thermocompression bonding, heat treatment or glass fiber; A one-pack coating film selected from a two-pack type reaction curing type waterproofing material selected from cement-incorporated polymer type, hydrated solid type, siliceous type, urethane / tar urethane rubber type and FRP or acrylic rubber type, chloroprene rubber type, acrylic urethane type, acrylic resin type and rubber asphalt type A structure in which at least one kind of waterproof material is laminated; A polyethylene / vinyl chloride resin sheet with a hard / soft vinyl chloride resin, a foamed or non-foamed ethylene-based sheet consisting of LLDPE, LLDPE + HDPE / LLDPE + LDPE, a PE polyethylene vinyl polymer having a VA + LLDPE, HDPE and a PE / EVA / VA content of 10 to 30% (PEVA), EPM, EPDM, EPT alone or as modified with polymer such as plasticized synthetic rubber based sheet by modification of LLDPE, LDPE, PE, synthetic rubber based sheet, synthetic resin APP and synthetic rubber SBS Sheet, a rubberized asphalt-based sheet using synthetic rubber, and a sheet to which an asphalt compound is applied.

간추리면, 보강재와 도막방수재, 직포, 1액형 도막방수재, 시트가 적층된 도막시트 일체형 복합방수재다.It is a composite waterproofing material with integral sheet, which is a laminated sheet with a reinforcing material, a coating material waterproofing material, a woven fabric, a one-liquid type coating film waterproofing material and a sheet.

그리고, 상기 도막시트 일체형 건식화 복합방수재는 두루말이형 보강재를 등속으로 풀어 내 타측에서 감아 들이면서 보강재의 편면에 1회 이상 도막방수재를 도포하여 건조한 도막방수층의 표면에 방수시트재를 압출 하여 접합해 일체화하는 과정을 거쳐 제조한다.The dry film composite waterproofing material with integral coating layer is formed by extruding the waterproof sheet material onto the surface of the dried film waterproof layer by applying the coating film waterproofing material to at least one side of the reinforcing material by winding the staple- It is manufactured through an integration process.

그러나, 이 선행기술은 3중 시트 적층구조이기 때문에 복합방수시트가 필요 이상 두꺼워 방수시공성이 떨어지고, 자재비와 생산성이 낮기 때문에 제조원가부담도 크며, 기능성 도막재가 결여된 탓에 방수공법별로 요구되는 방수기능을 충족시킬 수 없다.However, since this prior art is a triple-layered laminated structure, the composite waterproof sheet is thicker than necessary, resulting in poor waterproofing workability, low manufacturing costs and low productivity, and a large manufacturing cost burden. Since the functional coating material is lacking, Can not be satisfied.

지층 슬래브(바닥 슬래브)를 기준으로 지하층과 지상 구조물을 역타설공법으로 건축/토목구조물을 시공할 때 최하층의 외벽에 대한 방수공사가 마무리될 때까지는 지층의 외벽에서부터 방수를 개시하여 최하층의 외벽에 대한 방수로 마무리하는 데, 방수성이 약한 상기 선행기술의 도막시트 일체형 건식화 복합방수재는 도막방수층이 외벽을 향하든 그렇지 않든 간에 역타설공법으로 구축되는 지하구조물용 방수재로는 더더욱 부적합하다.
When building / civil structure is constructed by retrofitting the basement and ground structures based on the stratum slab (bottom slab), waterproofing starts from the outer wall of the stratum until the waterproofing work for the bottom wall is completed, The prior art dry composite composite waterproofing material of the prior art having a weak waterproofing property is more unsuitable as a waterproofing material for an underground structure constructed by retrofitting method regardless of whether the waterproofing layer is directed toward the outer wall or not.
