时尚·华贵的理石漆

随着建筑节能标准的出台,建筑物也要实施外墙外保温,但外挂贴件与保温层的膨胀系数相差较大,在季节变化过程中,大理石与保温层间的结合强度远不如大理石与混凝土基面间的结合强度;再则天然大理石的干挂铆固件属金属质,插入主体墙内形成了热量传导桥,影响保温效果。故而,在建筑物实施外墙外保温后,考虑到外挂件的安全性及保温性,天然大理石将逐步被取代。而富思特的专利产品理石漆是目前较好的选择,它的最大的应用领域在于替代建筑装饰的石材幕墙,既达到大理石的装饰效果,又大幅度降低工程成本。理石漆,亦称理石幕墙漆。顾名思义,是可以喷涂…

通体大理石瓷砖的技术研究

通体大理石瓷砖,是大瓷砖坯体与表面纹理颜色基本一致的大理石瓷砖的升级产品。天然石材的外表和内坯具有一致性,而传统大理石瓷砖在效果上很难达到这一点,从而,后期深度加工时遇到拉槽、倒角、圆弧等处理时就可以明显看到内部不同色彩的坯体,与瓷砖釉面效果形成巨大的反差,看起来很不协调,让人遗憾。而通体大理石瓷砖制作工艺及系统就是为了改进这一问题,要把坯体色彩与纹理做到接近表面效果,甚至一致,做到真正的表里如一。

Effect of different polymers on the efficiency of water‐borne methyl amine adduct as corrosion inhibitor for surface coatings

Styrene/acrylic emulsion copolymer and water‐based short oil urethane alkyd resin were used as binders to prepare water‐based, environmentally friendly paints by using 0.5% emulsified methylamine adduct as corrosion inhibitor. The choice of the two above‐mentioned binders was based on the fact that styrene/acrylic emulsion copolymer is a nonconvertible binder, whereas short oil urethane alkyd resin is a convertible binder. The physical, chemical, mechanical, and corrosion properties of the paint films were evaluated and compared with a commercially known anticorrosive water‐based paint. It was found that the prepared paints have unique desirable properties such as the following: they do not contain anticorrosive pigments (which contain heavy metals in their main chemical structure); they are solvent‐free; and they can be produced to match any color. Corrosion tests on the films of the formulated paints revealed that the short oil urethane alkyd resin is superior to the styrene/acrylic copolymer. Moreover, the corrosion inhibition properties of the paint films prepared from both binders are comparable with the commercially available paints containing anticorrosive pigments. © 2002 Wiley Periodicals, Inc.

Anticorrosive properties of the epoxy–cardanol resin based paints

An epoxy–cardanol resin was developed using epichlorohydrin, bisphenol-A and cardanol. On evaluation it was found that epoxy–cardanol resin exhibits better properties as compared to epoxy resin in terms of increase in tensile strength, elongation, bond with steel and lowering of water vapour transmission of the film. The improvement in these properties indicated that the paints based on modified resin would be more durable than the epoxy based paints. Accordingly, paints were formulated using the developed resin and their performance were compared with their counterparts made with unmodified epoxy resin. Zinc powder, zinc phosphate, micaceous iron oxide and synthetic iron oxide were used as pigments along with fillers, additives and an aromatic polyamine adduct hardener. For both types of paints similar doses of pigments and additives were used. Physico-mechanical properties, chemical resistance and corrosion protection efficiency of the formulated paints were determined. It was found that the anticorrosive properties of epoxy–cardanol resin based paints are superior to that of the paints formulated with the unmodified epoxy resin. Micaceous iron oxide based paints in epoxy–cardanol resin showed the best performance followed by zinc phosphate based paints. It is concluded that the developed resin is a better binder media for the formulation of paints.

High-build soluble matrix antifouling paints based on vinyl resin

The aim of this work was to formulate and evaluate high-build, soluble matrix antifouling paints showing reduced solvent retention in the film and sufficient bioactivity to protect structures submerged in sea water for long immersion periods.

The variables analyzed were binder composition, pigment content, toxicant type and thixotropic agent content.

Binder dissolution in sea water was achieved by employing WW rosin or calcium resinate; the control of the binder dissolution rate was achieved by using a vinyl resin as a cobinder. The paints were formulated with pigment volume concentrations of 40 and 45%; red cuprous oxide and triphenyl tin fluoride were used as the main toxicants. The rheological additive employed was hydrogenated castor oil at levels of 2.0 and 2.5 wt.% in the paint.

The bioactivity of the antifouling paints was determined in the natural environment (30 month immersion in sea water).
