Description

[발명의 명칭][Name of invention]

브레이크 부품 조립용 비광유 그리이스 조성물Non-mineral grease composition for assembly of brake parts

[발명의 상세한 설명]Detailed description of the invention

[산업상 이용분야][Industrial use]

본 발명은 브레이크 조립용 액체 그리이스에 관한 것으로서, 더욱 상세하게는 부품에 대한 부착성이 좋고, 도포성이 우수하며, 부식 방지성이 우수하고, 브레이크액과의 상용성이 우수한 브레이크 부품 조립용 비광유 그리이스 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid grease for assembling brakes, and more particularly, to a brake component assembly ratio having good adhesion to components, excellent applicability, excellent corrosion protection, and excellent compatibility with brake fluid. It relates to a mineral oil grease composition.

[종래기술][Private Technology]

브레이크 부품 조립용 그리이스는 브레이크 장치를 구성하는 마스터 실린더, 휠 실린더 등의 각종 부품을 가공한 후 피스톤, 스프링, 러버 컵 등을 실린더에 조립할 때 조립 작업을 용이하게 할 수 있도록 윤활 작용을 하며 장기 보관시에 부식의 발생을 막아 주기 위해 도포되는 조립용 액체 그리이스이다. 이와 같은 브레이크 부품 조립용 비광유 그리이스 조성물은 브레이크 장치의 구성부품 중의 하나인 러버 컵(rubber cup) 및 실(seal)에 악영향을 주지 않을 뿐만 아니라 자동차에 조립된 후 주입되는 비광유계 브레이크액과 상용성이 있어야만 한다. 그러나 종래의 브레이크 부품 조립용 그리이스는 반고상 상태로서 지방산의 비누기를 베이스 오일(Base oil)로 사용하여 만든 것으로서 부품에 부착 잔류성은 양호하나 도포 작업이 용이하지 못하고 전체면에 고루 도포할 수가 없어 부식 방지성이 좋지 않다는 문제점을 갖고 있으며, 브레이크액과의 상용성이 좋지 못하여 브레이크액을 오염시키거나 유기 지방족 화합물로 인해 러버 컵을 과대 팽윤시키는 문제점도 갖고 있다.Grease for assembling brake parts is processed for various parts such as master cylinder, wheel cylinder, etc., which make up the brake device, and then lubricated for easy assembly when piston, spring, rubber cup, etc. are assembled to the cylinder. It is an assembly liquid grease applied to prevent the occurrence of corrosion at the time. Such a non-mineral grease composition for assembling brake parts not only does not adversely affect the rubber cup and seal, which is one of the components of the brake device, but also the non-mineral oil-based brake fluid injected after being assembled into a vehicle. There must be compatibility. However, the conventional grease for assembling brake parts is a semi-solid state, which is made by using a fatty acid soap group as a base oil. It has a problem of poor prevention, and also has a problem of poor compatibility with the brake fluid to contaminate the brake fluid or overswell the rubber cup due to the organic aliphatic compound.

[본 발명이 해결하려 하는 과제][PROBLEMS TO BE SOLVED BY THE INVENTION]

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 첫째 부품에 대한 부착성이 양호할 뿐만 아니라 도포성이 우수하여 부식 방지 성능이 우수한 브레이크 부품 조립용 비광유 그리이스 조성물을 제공하고, 둘째 비강유계 브레이크액과 상용성이 우수한 브레이크 부품 조립용 비강유 그리이스 조성물을 제공하는 것을 목적으로 한다.The present invention has been made to solve the conventional problems as described above, the object of the present invention is a non-mineral grease for assembling brake parts excellent in anti-corrosion performance as well as good adhesion to the first component. It is an object to provide a composition, and secondly, to provide a non-oil grease composition for assembling brake parts having excellent compatibility with non-oil-based brake fluid.
