도 1을 참조하면, 본 실시 예의 방수제 조성물을 제조하기 위해서는, 먼저 DGEBA계 에폭시 수지 조성물(S60)을 마련한다.Referring to FIG. 1 , in order to prepare the waterproofing agent composition of this embodiment, first, a DGEBA-based epoxy resin composition (S60) is prepared.
이를 위해, DGEBA계 에폭시 수지 13~30중량부에 대하여, 아크릴산 에스테르(Acrylic Esters) 20~25중량부 및 메타크릴계 스티렌 20~25중량부를 혼합하여 용액 상태에서 스티렌화 된 1차 혼합물을 마련한다(S10).To this end, with respect to 13 to 30 parts by weight of the DGEBA-based epoxy resin, 20 to 25 parts by weight of acrylic esters and 20 to 25 parts by weight of methacrylic styrene are mixed to prepare a styrenated primary mixture in a solution state (S10).
상기 아크릴산 에스테르는 내후성이 우수한 킬복실기와 접착성이 우수한 에폭시기를 가지는데, 이러한 킬복실기와 에폭시기의 혼합에 의한 자기반응으로 방수제 조성물의 내후성, 접착성, 방수성, 내수성 및 내화학성을 향상시키는 역할을 하게 된다.The acrylic acid ester has a killboxyl group with excellent weather resistance and an epoxy group with excellent adhesion, and the self-reaction caused by the mixing of the killboxyl group and the epoxy group serves to improve the weather resistance, adhesion, waterproofness, water resistance and chemical resistance of the waterproofing agent composition. will do
이러한 아크릴산 에스테르가 20중량부 미만이면 상기의 여러가지 특성을 향상시키는 효과가 제대로 구현되지 못하게 되고, 상기 아크릴산 에스테르의 함량이 25중량부를 초과하면 경화지연 문제가 발생할 수 있다.If the amount of the acrylic acid ester is less than 20 parts by weight, the effect of improving the various properties may not be properly implemented, and if the content of the acrylic acid ester exceeds 25 parts by weight, a curing delay problem may occur.
다음으로, 스틴렌화 된 1차 혼합물에 수산기를 가지는 아마인유와 지방산을 추가하고 230℃로 가열하여 에스텔화 된 에스텔화 생성물을 마련한다(S20).Next, linseed oil and fatty acids having a hydroxyl group are added to the styrenated primary mixture and heated to 230° C. to prepare an esterified esterified product (S20).
다음으로, 상기 에스텔화 생성물 200중량부를 방향 탄산화 수용액에 녹인 후, 스티렌 100중량부와 디-t-부틸퍼어 옥사이드 4중량부를 추가하고, 135~140℃에서 3.5~4시간 동안 가열하여 2차 혼합물을 마련한다(S30).Next, after dissolving 200 parts by weight of the esterification product in an aqueous aromatic carbonation solution, 100 parts by weight of styrene and 4 parts by weight of di-t-butylperoxide are added, and the second mixture is heated at 135 to 140° C. for 3.5 to 4 hours. to prepare (S30).
다음으로, 상기 2차 혼합물 100중량부에 대하여 스티렌 50~55중량부를 결합시켜 3차 혼합물을 마련한다(S40). 이때, 상기 3차 혼합물은, 음이온으로 PH가 6.5~7.5이고, 활성분 95~98중량%와 인계면 활성제 2~5중량%로 수용화될 수 있다.Next, 50 to 55 parts by weight of styrene are combined with respect to 100 parts by weight of the secondary mixture to prepare a tertiary mixture (S40). At this time, the tertiary mixture, as an anion, has a pH of 6.5 to 7.5, and may be solubilized with 95 to 98% by weight of active ingredient and 2 to 5% by weight of phosphorus surfactant.
다음으로, 상기 3차 혼합물에 트리클로로실란과 올레핀을 첨가하고 과산화 촉매(45℃)로 반응시켜 알킬실란을 얻는다(S50). 그리고, 상기 알킬실란에 Si-O 결합시켜 얻은 화합물을 증유하면, 반량 이하는 환상인 디메틸실록산이면서 가교 만상화가 일어나는 고분자량의 DGEBA계 에폭시 수지 조성물을 마련할 수 있다(S60).Next, trichlorosilane and olefin are added to the tertiary mixture and reacted with a peroxidation catalyst (45° C.) to obtain alkylsilane (S50). And, if the compound obtained by bonding the Si-O to the alkylsilane is increased, a DGEBA-based epoxy resin composition having a high molecular weight in which crosslinking occurs while half weight is cyclic dimethylsiloxane can be prepared (S60).
이렇게 제조된 본 실시 예의 DGEBA계 에폭시 수지 조성물은 Si-O 결합을 분해하지 않고서는 순수 증유할 수 없는 화합물이므로 후술하는 무기계 조성물과 혼용하여 사용할 수 있다.The DGEBA-based epoxy resin composition of this embodiment prepared in this way is a compound that cannot be pure without decomposing the Si-O bond, so it can be used in combination with an inorganic composition to be described later.
다음으로, 경량골재 100중량부에 대하여 패각제 25~35중량부와 규산질 시멘트 30~35중량부를 혼합한다. 그리고, 앞서 공정을 통해 마련된 DGEBA계 에폭시 수지 조성물과 경화제를 함께 넣고 혼합하여 본 실시 예의 이액형의 방수제 조성물을 제조할 수 있다(S70).Next, 25 to 35 parts by weight of the shell agent and 30 to 35 parts by weight of siliceous cement are mixed with respect to 100 parts by weight of the lightweight aggregate. Then, the DGEBA-based epoxy resin composition prepared through the above process and the curing agent are put together and mixed to prepare the two-component waterproofing agent composition of this embodiment (S70).

이때, 바람직하게는 경량골재 4.0~6.0중량부에 대하여, 패각제 1.0중량부와 규산질 시멘트 1.0~1.2중량부의 비율로 혼합하고, 여기에 DGEBA계 에폭시 수지 조성물 20~24중량부와 경화제 10~12중량부를 더 포함할 수 있다. At this time, preferably, with respect to 4.0 to 6.0 parts by weight of the lightweight aggregate, 1.0 parts by weight of the shell agent and 1.0 to 1.2 parts by weight of the siliceous cement are mixed, and 20 to 24 parts by weight of the DGEBA-based epoxy resin composition and 10 to 12 parts by weight of the curing agent. It may further include parts by weight.
