Description
본 발명은 합성수지가 적층된 방수시트의 제조방법에 관한 것으로서, 보다 상세하게는 건조물의 방수층 시공이나 농업용 수로 및 저수용의 바닥방수에 사용되기에 적합하게 내구성 및 내후성이 증진된 합성수지가 적층된 방수시트를 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a waterproof sheet laminated with synthetic resin, and more particularly, waterproof and laminated with synthetic resin having enhanced durability and weatherability, which is suitable for use in construction of a waterproof layer of a dry product or for waterproofing a water channel and a bottom for water storage. It relates to a method of producing a sheet.
일반적으로, 내구성 및 내후성이 우수한 합성수지 적층 방수시트는 건조물의 루-핑재로서 천정부 내부에 상기 방수시트를 삽입하므로서, 건물의 방수기능을 만족시키고 또한 보강재의 역할도 할 수 있는 건조물 시공법에 사용되는 소재이다.In general, synthetic resin laminated waterproof sheet having excellent durability and weather resistance is a material used in a building construction method that satisfies the waterproof function of a building and also serves as a reinforcing material by inserting the waterproof sheet inside the ceiling as a roofing material of the building material. to be.
종래에, 방수시트로는 테데니어 폴리에스테르사를 사용한 후직물(매트)이나, 범용성 고무를 코팅한 방수시트를 사용하여 왔으므로, 방수기능이 저하되거나, 내구성이 떨어졌으며 내약품성 및 내오존성도 거의 없었을 뿐만아니라 내후성 또한 만족치 못하였다.Conventionally, the waterproof sheet has been used a post-woven fabric (mat) using a tidene polyester polyester, or a waterproof sheet coated with a general-purpose rubber, so that the waterproof function is lowered, the durability is poor, and the chemical resistance and ozone resistance are also high. Not only was it rare, but also the weatherability was not satisfactory.
이에 본 발명은 종래의 이러한 문제점을 해소시키기 위한 것으로서 완정방수에 의한 용수의 손실을 방지하며, 또한 토층 함몰 현상을 제거시킬 수 있는 반영구적으로 사용이 가능한 합성수지가 적층된 방수시트를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve such a problem in the prior art to prevent water loss due to complete waterproofing, and also to provide a waterproof sheet laminated with a synthetic resin that can be used semi-permanently, which can eliminate the soil dent phenomenon. have.
합성수지 적층 방수시트를 제조하는 방법에는 크게 코팅에 의한 방법과 라미네이팅에 의한 방법으로 나눌수 있는데, 라미네이팅 방법은 기포와의 접착성이 떨어지는 결점이 있으므로 본 발명에서는 코팅에 의한 방법을 사용하기로 한다.The method of manufacturing a synthetic resin laminated waterproof sheet can be largely divided into a coating method and a laminating method. Since the laminating method has a drawback of poor adhesion to bubbles, the method of coating is used in the present invention.
이하 본 발명은 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 수지, 유기용제, 접착제 및 기타 첨가제로 조성된 수지 조성물을 처기하여 합성수지가 적층된 방수시트를 제조함에 있어서, 다음 구조식(I)로 표시되는 클로로 술폰네이트 폴리에틸렌(CSPE)수지 35 내지 55중량%, 유기용매 30 내지 50중량%, 산화방지제 5 내지 15중량% 및 폴리에스테르계 접착제 5 내지 15중량%를 혼합시킨후, 상기 혼합 수지조성물을 교반·밀링하고 섬유포지 양면에 도포 시킨다음 120 내지 130℃에서 2분간 건조시키고 180 내지 190℃에서 열처리시켜서 되는 합성수지가 적층된 방수시트의 제조방법임을 그 특징으로 한다.The present invention is to prepare a waterproof sheet laminated synthetic resin by disposing a resin composition composed of a resin, an organic solvent, an adhesive and other additives, chloro sulfonate polyethylene (CSPE) resin represented by the following structural formula (I) 35 to 55 After mixing by weight%, organic solvent 30 to 50% by weight, antioxidant 5 to 15% by weight and polyester adhesive 5 to 15% by weight, the mixed resin composition is stirred and milled and coated on both sides of the fiber cloth 120 It is characterized in that it is a method for producing a waterproof sheet laminated synthetic resin by drying for 2 minutes at 130 to 130 ℃ and heat treatment at 180 to 190 ℃.
상기식에서, X는 8 내지 14의 정수이고, n은 10 내지 17의 정수이다.Wherein X is an integer from 8 to 14 and n is an integer from 10 to 17.
이하 본 발명은 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명은 수지, 유기용제, 접착제 및 기타 첨가제로 조성된 수지 조성물을 처리하여 합성수지가 적층된 방수시트를 제조함에 있어 내구성 및 내후성을 증진시킬 목적으로 200 내지 800의 분자량을 가지는 폴리에스테르계 수지를 35 내지 55중량%사용하는바, 이때 그 사용량을 35중량% 미만으로 할 경우에는 가교결합이 적게 되므로서 완전방수가 되지 않게되며 55중량%를 초과하여 사용할 경우에는 공정상의 어려움과 아울러 55중량% 일때의 효과와 거의 같게되는 포화상태가 된다.The present invention is a polyester resin having a molecular weight of 200 to 800 for the purpose of improving the durability and weather resistance in the manufacture of a waterproof sheet laminated with synthetic resin by treating the resin composition composed of a resin, an organic solvent, an adhesive and other additives When used 35 to 55% by weight, when the amount is less than 35% by weight is less cross-linking, so that it is not completely waterproof, when used in excess of 55% by weight 55% by weight with the difficulty of the process The saturation is almost the same as when
본 발명에서 폴리에스테르계 수지로 사용되는 클로르 술폰네이트 폴리에틸렌(CSPE)는 술폰닐콜로라이드를 가지고 있으므로 습기 또는 자외선에 노출되면 술포닐클로라이드를 가지고 있으므로 습기 또는 자외선에 노출되면 술포닐 콜로라이드기가 금속계 산화방지제와 메탈술폰네이트 가교결합에 의해 다음 구조식(II)로 표시되는 공간가교(space vulcanization)되므로 내후성 및 내구성의 증가에 기여하게 된다.Since the chlor sulfonate polyethylene (CSPE) used as the polyester resin in the present invention has sulfonyl collide, it has sulfonyl chloride when exposed to moisture or ultraviolet rays, and thus the sulfonyl collide group is oxidized when exposed to moisture or ultraviolet rays. Space vulcanization, represented by the following structural formula (II), by the metal sulfonate crosslinking agent, contributes to the increase in weather resistance and durability.
상기식에서, X는 8 내지 14의 정수이고, n은 10 내지 17의 정수이다.Wherein X is an integer from 8 to 14 and n is an integer from 10 to 17.
상기에서 공간가교란 기본수지인 CSPE수지에 금속계 산화방지제인 PbC12를 첨가했을때 분자간에 가교결합이 되는 현상을 나타낸다.In the above, spatial crosslinking refers to a phenomenon in which crosslinking occurs between molecules when PbC1 2 , a metal-based antioxidant, is added to CSPE resin, which is a basic resin.
또한, 유기용매로서는 톨루엔 또는 부탄올을 사용하며, 30 내지 50중량%가 바람직한바, 상기 범위를 벗어날 경우에는 공정상 어려움이 생기게 된다.In addition, toluene or butanol is used as the organic solvent, and 30 to 50% by weight is preferable.
그리고, 산화방지제로는 금속계 산화방지제인 염화납, 염화마그네슘, 염화아연 등을 사용하며 5 내지 15중량%가 바람직한 바, 만약 5중량% 미만을 사용할 경우에는 가교결합이 적게 되므로서 완전방수가 되지 않으며, 15중량%를 초과하여 사용할 경우에는 15중량%일때의 효과와 거의 같게 되므로 원가 면에서 불리하다.As the antioxidant, metal chlorides such as lead chloride, magnesium chloride, and zinc chloride are used, and 5 to 15% by weight is preferable. If less than 5% by weight, crosslinking is less, it is completely waterproof. If it is used in excess of 15% by weight, it is almost the same as the effect of 15% by weight, which is disadvantageous in terms of cost.
접착제로는 널리 공지되어 있는 분자량이 20,000 내지 25,000의 폴리에스테르계 접착제를 5 내지 15중량% 사용한다.As the adhesive, a polyester adhesive having a well-known molecular weight of 20,000 to 25,000 is used in an amount of 5 to 15% by weight.
이어서 상기의 성분들을 교반, 밀링으로 혼합시켜서 된 수지 조성물을 섬유포지 양면에 도포시킨 다음 120 내지 130℃에서 2분간 건조시키고, 180내지 190℃에서 열처리시켰는 바, 열처리 과정에서 술폰닐 클로라이드기가 상기 구조식(II)로 표시되는 가교반응을 일으켜 금속 술폰네이드 가교결합구조로 됨으로서 내구성 및 내후성이 우수한 합성수지 방수시-트가 제조되게 된다.Subsequently, the resin composition obtained by mixing the above components by stirring and milling was applied to both sides of the fiber cloth, dried at 120 to 130 ° C. for 2 minutes, and heat-treated at 180 to 190 ° C., in which the sulfonyl chloride group was used as the structural formula. By producing a crosslinking reaction represented by (II) to form a metal sulfonide crosslinking structure, a synthetic resin waterproof sheet having excellent durability and weather resistance is produced.
본 발명에 따라 제조된 방수시트를 건조물의 방수층 시공이나 농업용수로 및 저수용의 바닥 방수에 사용함으로서 용수의 손실을 방지하며 토층함몰 현상을 제거할 수 있으며, 반영구적으로 사용할 수 있게 된다.By using the waterproof sheet manufactured in accordance with the present invention in the construction of the waterproof layer of the building or waterproofing the bottom of water for agriculture and water storage, it is possible to prevent the loss of water and to remove the ground dent phenomenon, it can be used semi-permanently.
