Abstract

In this study, three softwood species were treated with water-soluble melamine resin by different concentration and treatment time under vacuum pressure for improving mechanical property, abrasion resistance, and incombustibility. After the treatment, a compreg was manufactured and then evaluated on physical properties. Additionally, incombustibility of compreg was determined by comparing with a wood that was treated by spraying a water-soluble fire retardant on surface. As concentration of resin increased, bending strength and Brinell hardness increased as well as abrasion resistance, but there was no correlation on treatment and mechanical properties by treatment time. The wood impregnated by water-soluble melamine resin under vacuum pressure showed better incombustibility than that of a water-soluble fire retardant sprayed wood. Therefore, this treatment could be used for improving incombustibility of wood.

진공가압 수지함침 처리에 의한 목재의 휨강도, 경도 및 내마모성 향상을 위하여 침엽수 3수종에 수용성 멜라민 수지를 수지농도와 처리시간별로 진공가압 처리한 후 수지함침 열압축목재(compreg)를 제조한 다음 물성을 검토하였다. 또한 같은 수종에 수용성 난연제를 도포처리하는 방법과 진공가압 후 열압처리 방법으로 제조한 다음 난연성 향상정도를 측정하였다. 수지의 농도가 높을수록 휨강도 및 브리넬 경도는 증가하였고 내마모성은 향상되었으나, 처리시간과는 일정한 경향이 없었다. 난연성은 도포시험편 보다 진공가압처리 시험편이 총 방출열량이 감소하여 진공가압처리에 의한 난연성 개선 방법이 효과가 있었다.
