户外用聚乙烯蜡物理改性研究
摘 要：本文介绍了户外用聚乙烯蜡的研究背景、研究目的及意义，分析了国内外同类研究的概况，详述了主要研究内容及过程，提出了研究的特色及创新。采用聚乙烯蜡涂饰户外木材建筑小品等，虽然其具有良好的耐虫害效果，而且具有不易变形，稳定性良好的优点，但是它的颜色衰弱明显，容易褪色。而本实验就是针对聚乙烯蜡的褪色问题，对其配方进行研究，使其不宜褪色或者降低其颜色衰弱的程度。

Study on physical modification of polyethylene wax for outdoor use
Abstract: This article introduces the research background, purpose and significance of outdoor polyethylene wax, analyzed the general situation of similar research at home and abroad, details the main research content and process,and puts forward the research characteristics and innovation. Polyethylene wax coating is used to decorate outdoor wood buildings,although it has good insect resistance effect,and has the advantages of not easy to deformation ,good stability,but its color is weak and obvious,easy to fade.This experiment is aimed at the problem of polyethylene wax discoloration. The formula of polyethylene wax is studied to make it not easy to fade or reduce the degree of color weakness.
Keywords: polyethylene wax,color weakness,paint,outdoor,physical modification
