浅谈真石漆涂层之真石漆中间层

日期:2016年7月7日 浏览[998]

真石漆中间层 真石漆中间层是由骨料,粘结剂(基料),各种助剂和溶剂组成.  骨料 骨料包括彩色骨料和普通骨料两种. 彩色骨料是天然石材经过粉碎,清洗,筛选等多道工序加工而成,具有很好的耐候性,耐酸碱和不褪色性


Middle layer of lacquer of lacquer layer in the middle is the aggregate, binder (base material), various additives and solvent composition.?? Aggregate aggregate including colored aggregate and normal aggregate two. Colored aggregate is natural stone material after crushing, cleaning, screening multi-step processing and and has good weather resistance, acid and alkali resistance and fastness


为非人工烧结彩砂.普通骨料选择白度好,含硅量高的石英砂,由于天然石粉颜色比较暗淡,单独使用时颜色比较呆板,用一定量的白色石英砂与天然彩色石粉配合使用,可调整颜色的深浅,使涂层的色调富有层次感,能取得类似天然石材的质感,同时也降低了生产成本.


For the non artificial sintered sand. Ordinary aggregate to the choice of good whiteness, high silicon content of quartz sand, due to the natural stone powder color is dim, when used alone, color dull, with a certain amount of white quartz sand and natural color powder with the use of, shades of the color adjustment, the coating of the tone of a rich sense of the level, can achieve similar to natural stone texture, while also reducing the production cost.


骨料的颗粒级配对真石漆的施工性及涂层的表现状态影响非常大,如果骨料颗粒太粗,在涂料中易沉淀,喷涂时落地砂也会增多,涂料的用量会大,而且涂层的遮盖力下降,涂层外观粗糙,易积灰尘而被污染;如骨料颗粒太细,则装饰效果欠佳.所以,采用粗细颗粒搭配使用,既不易影响涂层的装饰效果,还可以使涂层致密. ‚


Particles of the aggregate level pairing of lacquer construction and coating performance influence is very large, if the aggregate particles is too coarse, in the paint is easy to precipitate, spraying floor sand will also increase, the amount of coating will be, and the coating coverage decreased, the appearance of the coating rough, easy to accumulate dust and pollution; such as aggregate particles are too small, decorative effect is poor. Therefore, the use of particle size collocation is used, is not easy to affect the coating decorative effect, can also the density of coating. "


粘结剂(基料) 粘结剂是影响真石漆性能的关键因素之一,它的好坏直接影响着真石漆膜的硬度,粘结强度,耐水,耐候等多方面的性能.用于真石漆的乳液应该满足下列三方面的要求:


Binder (base material) binder is one of the key factors influencing the performance of the lacquer, its quality directly affects the real stone paint film hardness, bonding strength, water resistance, weather resistance and other aspects of performance. For lacquer emulsion should meet the requirements of the following three aspects:


A 乳液稳定,所形成的漆膜无色,透明,在紫外线照射下不易发黄和粉化;


A emulsion is stable, the formation of colorless, transparent, transparent, in the ultraviolet light is not easy to yellow and pink;


B涂膜的硬度要高,以提高涂层的耐沾污性;


B film hardness is high, in order to improve the stain resistance of coating;


C,漆膜的吸水膨胀率要小,形成耐水耐白化的漆膜,即具有抗吸水泛白的能力.


C film, the swelling ratio is smaller, the formation of water resistance and whitening film, which has the ability of anti white water.
