Description
본 발명은 이형제에 관한 것으로 특히 이형제의 용제를 수성으로 하고 여기에 방청제를 첨가하여 제조함으로써, 기존 이형제의 제조시 유성 용제를 사용함으로써 발생하였던 인체에의 피해를 줄이고, 또한 몰드의 부식을 방지할 수 있도록 한 방청수성이형제에 관한 것이다.The present invention relates to a mold releasing agent, in particular, by making the solvent of the releasing agent aqueous and adding a rust preventive agent, thereby reducing damage to the human body caused by using an oil-based solvent in the manufacture of a conventional mold release agent, and also prevents corrosion of the mold. The present invention relates to a rust preventive brother.
현재 날로 심화되고 있는 환경오염과 산업근로자의 건강을 보호하기 위하여 각 방면에 걸쳐 많은 노력이 진행되고 있는데, 이러한 노력은 기초 산업 부문에서도 활발히 벌어지고 있다. 한편 몰드 작업은 1 차 산업의 각 부분에서 매우 비중이 크며 몰드 작업 공정에 있어서 이형제제는 필수적으로 사용되고 있다.A lot of efforts are being made in various fields to protect the environmental pollution and the health of industrial workers, which are intensifying day by day. On the other hand, mold work is very important in each part of the primary industry, and release agents are indispensable in the mold work process.
이 때 일반적으로 이형제란 성형품 금형에서 떨어지는 것을 용이하게 하기 위해 금형에 바르는 약제를 말한다. 그런데 기존의 이형제들은 대부분 유기 용제를 베이스로 사용하기 때문에 이형성은 뛰어나나, 작업시 인체에 해를 주는 경우가 발생하게 된다. 이를 해소하기 위해서는 이형제의 용제를 물로 전환하는 것이 필요한데, 물을 베이스로 한 수성 이형제의 가장 큰 단점은 몰드가 돌과 결합하여 몰드의 부식이 일어난다는 것이다.In this case, the release agent generally refers to a drug applied to a mold in order to facilitate the falling out of the mold. By the way, the existing release agents are excellent in mold release because most of the organic solvent is used as a base, it occurs when the harm to the human body at work. In order to solve this problem, it is necessary to convert the solvent of the release agent into water. The biggest disadvantage of the water-based aqueous release agent is that the mold is combined with stones to cause corrosion of the mold.
본 발명은 상기한 문제점을 해결하기 위해 마련된 것으로 이형제의 용제를 수성으로 함과 동시에 몰드가 부식되지 않도록 방청효과를 갖도록 한 방청수성이형제를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide an anti-rust forming agent having an anti-rusting effect to make the solvent of the release agent aqueous and at the same time not to corrode the mold.
