스프레이식 수용성 제진재 및 그 조성물Spray-type water-based vibration damper and composition

이 발명은 스프레이식 수용성 제진재(vibration reduction Material)를 제안하려는 것으로, 특히 환경 친화적이고 온도 의존성이 낮은 스프레이식(Sprayable) 수용성 제진재 및 그 조성물에 관한 것이다.The present invention intends to propose a spray type water-soluble vibration damping material, and more particularly relates to a sprayable water-soluble vibration damping material and composition thereof which are environmentally friendly and low in temperature dependence.

제진재는 성상에 따라 ① 고체상태(nonreactive type) ② 액체상태에서 고체로 변화하는 타입(reactive type)으로 분류 할 수 있으며, 특히 스프레타입(spray type)의 액체상태 제진재 로서는 ⓐ 유용성(가소제, Solvent매체)과 ⓑ 수용성 (H2O를 매체로 하는것)으로 나눌 수 있다.Vibration dampers can be classified into ① solid state (nonreactive type) ② liquid type to solid type (reactive type), especially as spray type liquid type vibration damper. Solvent medium) and ⓑ water-soluble (H 2 O as a medium).

스프레이 가능한 액상타입 에서는 유용성에서 발생하는 VOC의 문제, Ozone파괴 등의 생태계에 큰 피해를 끼치는 문제가 해결 가능므로 수용성 타입으로 전환되고 있다.In the sprayable liquid type, problems that cause great damage to the ecosystem such as VOC and Ozone destruction caused by usability can be solved.

자동차 산업에는 차체의 경량화, 엔진의 고출력 등에 의해 소음과 진동 문제가 핫 이슈로 되어 있으므로 이에 대한 방음, 제진재의 개발이 급속이 진전되고 있다. 방음, 제진재 중에서 가장 대표적인 아스팔트 시트(Asphale sheet)는 1960년대 후반부터 자동차의 차상(floor)에 사용되어 지금까지 주류를 이루고 있다. 사용량은 승용차 1대당 10~20kg 정도로 차체에 사용되는 비금속 재료 사용량 가운데 큰 비중을 점하고 있으나; 아스팔트는 유용성 이고 열경화하여 사용되므로 가열 경화시에 발생하는 VOC의 문제, 냄새(악취) 등의 환경 파괴적 요소와; 차량의 화재시에 매연 발생 하므로 인명피해의 위험을 내포하고 있으며; 제진재 부여공정에 인력배치가 크게되는 문제점이 있는 것이다. 또한 제진성능을 보더라도 낮은온도(20℃)에서 제진성능이 양호하나(도1 그래프참조) 높은온도(40℃, 60℃)에서 제진성능이 급격히 떨어지는 치명적인 결점을 가지는 것이다.In the automobile industry, noise and vibration problems are hot issues due to light weight of the vehicle body and high power of the engine, and thus, the development of sound insulation and vibration damping materials is rapidly progressing. Asphalt sheet, the most representative of the soundproofing and vibration damping materials, has been used in car floors since the late 1960s and has been mainstream until now. The use amount is about 10-20kg per passenger car, but the use amount of the nonmetallic material used in the car body is big; Asphalt is oil-soluble and is used by heat curing, and environmentally destructive elements such as VOC problems, odors (odors) that occur during heat curing; Smoke is generated in the event of a vehicle fire, which poses a danger of human injury; There is a problem in that the placement of personnel in the vibration damping process. In addition, even when the vibration damping performance is seen, the vibration damping performance is good at a low temperature (20 ° C.) (see FIG. 1 graph), but at a high temperature (40 ° C. and 60 ° C.), the vibration damping performance is rapidly deteriorated.
