摘要:三聚氰胺板具有质轻、防霉、防火、耐热、抗震、易清理、可再生,还可替代木制板材、铝塑板等做成镜面、高耐磨、防静电、浮雕、金属等饰面等优点,近年来得到较大的发展。本文介绍了三聚氰胺板基本组成、应用范畴、工艺现状、性能优缺和常见的制备方法并提出其未来发展趋势。并且还对热压工艺参数的确定和改性剂对三聚氰胺浸渍纸的饰面刨花板理化性能(耐污性、耐水蒸气、耐龟裂)的影响进行试验研究,确定改性剂最佳比例。本次实验结果表明当热压压力为2MPa,热压温度为160℃,热压时间为150s,树脂:固化剂:稀释剂:偶联剂为100:1.5:1:1时,三聚氰胺浸渍纸的饰面刨花板理化性能(耐污性、耐水蒸气、耐龟裂)最佳。 27742 毕业论文关键词:三聚氰胺甲醛树脂;改性;低压短周期;理化性能
Preparation and Performance Testing of Composite Decorative Board
Abstract: Because of the advantages of light weight, anti mildew,fire,heat resistant, easy to clean,renewable,seismic,but also can replace wooden plate, aluminum plate made of mirror, high wear resistance, electrostatic prevention,relief,metal finishing etc., melamine formaldehyde resin gets great development in recent years. This paper introduces the basic composition, melamine board application category, technology status, advantages and disadvantages of the common properties and preparation methods and put forward the future development trend.And also study on the hot pressing process parameters and modifying agent of melamine impregnated paper veneer particleboard physicochemical properties (stain resistance, resistance to water vapor, resistance to cracking) test,to determine the best ratio of modified agent.The experimental results show that when the pressure is 2MPa, the hot pressing temperature is 160 ℃, hot pressing time was 150s, the resin: hardener: thinner: coupling agent was 100:1.5:1:1, melamine impregnated paper veneer particleboard physicochemical properties (stain resistance, water vapour resistance,resistance to cracking) of the best.
