试谈当前涂料的热点──多彩涂料、仿瓷涂料、标志涂料

随着经济发展和人民生活水平的提高，各种新型涂料应运而生，象多彩涂料、仿瓷涂料和标志涂料等都成为当前涂料的热点。这里就这几种涂料的发展情况谈点看法。一、多彩涂料我国五、六十年代在美术漆中有裂纹漆和疙瘩漆，利用底漆和面漆之间表面张力的不同而使涂膜形成条状或粒状的彩色花纹，这种花纹是需两次施工才能形成的。多彩涂料是指一次性涂装能形成彩色花纹的涂料、其特征是用液状或胶体状二种或多种颜色的粒子制成悬浊状的涂料，主要用喷涂方法一次涂装形成彩色花纹。目前，国外只有日、美、英、荷等国生产多彩涂料，市售商品主要是…

漆、油漆、涂料及其它

关于从“漆”、“油漆”到“涂料”的转变过程,曾在社会上引起一些混乱认识,为澄清并解释其演变过程,本刊2005年第8期赵全生先生一文——“‘涂料’与‘油漆’解读”已叙及此,并提出了个人观点——涂料包括液体涂料(包括油性涂料和水性涂料)及固体涂料(即粉末涂料)。此文一经发表,遂引起业内专家的共鸣,本刊先后又收到涂料届老专家朱传棨、马庆麟的有关“漆”的起源、沿革及对“涂料”理解的撰文。而最终归为:“涂料”一词替代“油漆”一词的科学性,在行业内已成共识,此共识行业协会等相关部门应加大宣传,使国家统计局及社会对“涂料”的含义给予认可,以期更科学规范地制定涂料及其分类标准。

Development of matte finishes in electrostatic (EFB) and conventional hot dipping (CHDFB) fluidized bed coating process

This study focuses on the correlation between the thermo-rheological properties of a thermosetting powder coating system with its surface structure build-up. Epoxy powder coating systems, which displayed surface matting and surface wrinkling, were examined. Firstly, the evolution of the complex viscosity was correlated with the cure kinetic. Secondly, the structure build-up on the surface of the coatings was investigated with a combined SEM-CLA profilometry analysis at different stages of curing process for both EFB and CHDFB coating processes. Different finishes were found to characterize the films applied by using EFB and CHDFB coating processes as a result of the different way the film is heated by. Finally, a strict relationship of film morphology to the degree of conversion and to the evolution of the complex viscosity was found out for both EFB and CHDFB coating processes. The surface structure is built up after gelation point and continues to evolve after gelation with a full development of the film fine structure. Differences were observed in the surface structure build-up when different curing temperature was used, thereby indicating an influence of minimum viscosity on achievable finishing.     

Flash IR pre-curing of the decorative layer in metal-flake powder coatings

Metal-flake powder coatings are a special class of metallic paint finishes composed of two superimposed layers: a pigmented decorative base coat and an overlaying transparent protective top coat. In the present investigation, a novel curing procedure for such bilayer coatings is proposed. Flash IR pre-curing of the base coat promotes the formation of a surface diffusion barrier and limits movement of the decorative pigments and metal flakes around their initial positions. Oven baking after deposition of the top coat then completes curing of the bilayer coating. The influence of the IR intensity and irradiation time on the final properties of bilayer coatings was investigated. The visual appearance, surface morphology and scratch resistance were evaluated. Experimental findings revealed that the hybrid IR/oven baking curing procedure is a viable method for obtaining bilayer powder coatings with outstanding properties in a shorter processing time and with considerable energy savings.

Nanoclay dispersion effects on UV coatings curing

Clay-based nanocomposites have already shown their great potential. In this study, clay–acrylate nanocomposite formulations, for wood finishes, were prepared in four differents ways. High-speed mixing, ball milling, bead milling and three roll milling were used to disperse clay into the neat acrylate formulation. The viscosity of the formulations was determined. Small angle X-ray scattering and transmission electron microscopy experiments were performed on these samples in order to study the quality of the dispersion. Then, photo-calorimetry and real-time infrared spectroscopy were used in order to investigate the effects of clay loading and clay dispersion on the ultraviolet curing. These studies have shown that UV curing is related to the quality of clay dispersion. Presence of large clay aggregates decreases the conversion of the acrylate functional groups, even at a small clay loading. However, a small amount of clay, well dispersed, can help UV curing.

Advances in environmentally benign coatings and adhesives

There is an increased need to develop environmentally benign (no pollution or release of hazardous materials into the air, water or soil from a coating or adhesive either during their manufacture, use and disposal or recycle lifetimes), coatings and adhesives that have equivalent or superior properties to their conventional (non-environmentally benign) counterparts. This paper discusses some of the new concepts or technologies associated with environmentally benign barrier coatings for packaging, abrasion resistant coatings for plastic substrates, new developments in wood finishes, antifouling coatings and new chemistry associated with the design of advanced coating systems. This paper also discusses how Battelle is helping the US Air Force to eliminate hazardous waste associated with structural adhesive technology through the identification of equivalent adhesive systems reducing the number of adhesives used to repair current aircraft and missile equipment. This paper also discusses advances in the area of repulpable/recyclable pressure sensitive adhesives and silicone release coatings used in a variety of commercial applications.
