Description

시멘트 방수제의 제조방법Manufacturing method of cement waterproofing agent

본 발명은 스트레이트 아스팔트에 스티렌 모노머를 첨가 중합시키고 여기에 카본블랙, 고분자수지, 동물성 유지를 유기용제에 용해하여 가한 다음 폴리머 에멀젼을 첨가하여 제조되는 시멘트 방수제의 제법에 관한 것이다.The present invention relates to a method for producing a cement waterproofing agent prepared by adding and polymerizing a styrene monomer to straight asphalt, adding carbon black, a polymer resin, and an animal fat and oil to an organic solvent, and then adding a polymer emulsion.

종래의 시멘트 방수제는 강도 및 내성 부분에서 여름과 겨울에 차이가 큰 결점에 있으며 방수성, 접착성 및 탄성이 양호한 피막을 형성하지 못한 문제점들이 있어 그 만큼 이용 범위가 제한되었던 것이다.Conventional cement waterproofing agent has a drawback that the difference in strength and resistance in summer and winter, and there is a problem in not forming a good waterproof, adhesive and elastic coating, so that the use range has been limited.

본 발명자는 이러한 문제점을 해결하고저 한 것으로서 스트레이트 아스팔트에 스티렌 모노머를 첨가 중합하여 카본블랙과 고분자 수지인 폴리프로필렌 및 동물성 유지를 유기용제에 용해한 다음 이 용해액에 폴리머 에멀젼을 소량 첨가하고 상기 중합물에 혼합하여 제조한 제품으로, 형성된 피막은 제품 중 수지계통의 성분에 의해 내약품 및 내충격성을 강하게 해주고 탄성이 우수하여 모체와의 부착성이 강한 시멘트 방수제를 개발하게 된 것이다.The present inventors have solved this problem, and as a result, styrene monomer is added and polymerized to straight asphalt to dissolve polypropylene and animal fats, which are carbon black and a polymer resin, in an organic solvent, and then a small amount of a polymer emulsion is added to the solution to the polymer. As a product manufactured by mixing, the formed coating is to strengthen the chemical resistance and impact resistance by the components of the resin system of the product and to develop a cement waterproofing agent having a strong elasticity and excellent adhesion to the mother.

본 발명을 제조함에 앞서 각 재료의 특성을 알아보면 아스팔트로는 스트레이트아스팔트, 부로운 아스팔트로 크게 나눌 수 있는데 본 발명에서는 스트레이트 아스팔트를 사용하였고 스티렌 모노머는 아스팔트와 중합시켜 이를 사용하며, 폴리머 에멀젼으로는 폴리비닐 아세테이트, 폴리스티렌, 메틸메타 아크릴레이트, 에틸메타 아크릴레이트등이 있는데 어느 것을 사용하여도 관계가 없으나 전체 고형분이 5-30%중량인 폴리비닐 아세테이트를 사용함이 좋다.Before preparing the present invention, the characteristics of each material can be broadly divided into asphalt and straight asphalt, and asphalt asphalt. In the present invention, straight asphalt is used, and styrene monomer is polymerized with asphalt to use it, and as a polymer emulsion, There are polyvinyl acetate, polystyrene, methyl methacrylate, ethyl methacrylate, etc., which may be used, but polyvinyl acetate having a total solid content of 5-30% by weight is preferable.

카본블랙은 입경은 30매쉬 이상인 공업제품이 적당하며 좋키로는 30-40매쉬의 것이고 이는 수밀성을 증대시키며 방수성을 높이고 건조, 수축과 온도 팽창 및 동결 용해시 팽창력을 감소시켜 균열발생을 예방하여 내구성과 내연성을 높여주는 우수산 방수 효과를 갖고 분산체로서 소수성 성분들이 시멘트와 잘 혼합되는 성질을 가지고 있으나 제조시 배합비의 범위를 벗어나 방수효과가 현저히 떨어지는 효과를 방지해야 한다. 고분자 수지로는 폴리프로필렌과 폴리에틸렌 옥사이드를 사용하며 폴리프로필렌은 액 투과성이 적고 내열, 내약품성이 우수한 입도가 200-300매쉬인 것이 좋다.Carbon black is suitable for industrial products with a particle size of 30 mesh or more, preferably 30-40 mesh, which enhances water tightness, improves water resistance, and decreases the expansion force during drying, shrinkage and temperature expansion and freeze-melting to prevent cracking. It has a superior acid waterproofing effect that improves flame retardancy and hydrophobic constituents as a dispersion, and it has a property of mixing well with cement. Polypropylene and polyethylene oxide are used as the polymer resin, and polypropylene is preferably a particle size of 200-300 mesh having low liquid permeability and excellent heat resistance and chemical resistance.

폴리에틸렌 옥사이드는 시중에서 쉽게 구할 수 있는 것을 사용하여 부식방지 및 접착력을 우수하게 만든다. 동물성 유지로는 우지, 돈지, 로래유, 어유등이 있는데 전체 고형분이 40-80%중량인 것이 좋다.Polyethylene oxide is made available on the market to provide excellent corrosion protection and adhesion. Animal fats and fats include beef fat, pork fat, raw oil, fish oil, etc. The total solid content of 40-80% by weight is good.
