为考察砂壁状仿砖涂料中乳液Tg与成膜剂添加量的关系,不同颜料体积浓度对漆膜性能的影响,沙子对仿砖涂料配制工艺及性能的影响,以6种不同乳液为基料,以湖北地区普通河沙为主要填料,添加多种助剂配制成砂壁状仿砖外墙涂料,并对涂料进行观察和性能检测。结果表明:以沙子为主要填料可配制出砂壁状效果逼真的外墙仿砖涂料,乳液Tg越高、沙子占颜填料总体积比例越大,则成膜助剂添加量越大,当沙子占颜填料体积的62.5%时,涂膜砂壁状效果逼真、耐水性能良好,与使用石英砂为主要填料相比降低了成本,但成膜助剂添加量增加。以沙子为主要填料配制仿砖涂料时,颜填料使用高速分散机充分分散而不经研磨即能达到要求。 相似文献

根据中日两国对合成树脂乳液砂壁状建筑涂料和复层建筑涂料的标准要求进行分析,结合生产实际,得出建筑涂料的附着力要求,即:建筑涂料涂膜的粘结强度0.04 MPa是够用的;粘结强度的有效数字1位就够了;涂料的粘结强度要求一般不应高于腻子的粘结强度要求;建筑涂料涂膜的粘结强度不是建筑涂料的短板,而是长板。 相似文献

In this study, water-borne coating formulations which could be cured quickly were prepared using acrylic emulsion as the major coating constituent and highly reactive melamine resin as curing agent, and further incorporating a variety of additives. Melamine and acrylic types, melamine/acrylic mass ratio in coating formulation, and curing temperature were found to influence the performance of cured coatings. When melamine resin etherified slightly with methanol was used as curing agent, melamine/acrylic mass ratio was 0.45 and the coating formulation was baked at 170°C for 30 s, it was observed that performance of cured coating was the best. FTIR was used to study molecular structural changes of coatings after curing, and to analyze the cure mechanism of the coating. DSC was used to study the range of temperature in which curing occurred. The water-borne coating prepared in this study could be cured quickly when it was applied on decorative paper surface and baked at high temperature. Performance properties of cured coatings were tested according to standard methods, it was observed that dry heat resistance, wet heat resistance, adhesion, pencil hardness, and stain resistance all met standard requirements. 相似文献

Evaluation of fire performance of organic fire retardant free acrylic based coatings applied on various building materials by cone calorimetric method 下载免费PDF全文
Fire performance of water‐based plaster systems containing acrylic copolymer binder and non‐flammable mineral and ceramic fillers intended for decorative coating application was determined by cone calorimetric method. The coatings were applied on common building substrate materials used in construction sector, namely, Medium Density Fibre (MDF) boards, Gypsum Boards (GIB) and Stainless Steel (SS), and the different plaster finishes attempted on these substrates were Tierrafino, Suave and Bone China respectively. Group numbers of the different test samples were also evaluated following the Kokkala method. Based on various measurements, especially heat release, smoke evolution, mass loss data and the Group number estimates, it is evident that these organic fire retardant free coatings can offer good fire safety if applied on appropriate substrates like GIB or SS.
