贵阳真石漆厂家与您聊聊真石漆属于涂料吗?

贵阳真石漆厂家概述如下:真石漆是一种装饰效果酷似大理石、花岗石。主要采用各种颜色的天然石粉配制而成。真石漆装修后的建筑物,具有天然真实的自然色泽,给人以高雅、和谐、庄重之美感。适合于各类建筑物的室内外装修。特别是在曲面建筑物上装饰,可以收到生动逼真,回归自然的功效。真石漆具有防火、防水、耐酸碱、耐污染。无毒、无味、粘接力强,永不褪色等特点,能有效地阻止外界恶劣环境对建筑物侵蚀,延长建筑物的寿命,由于真石漆具备良好的附着力和耐冻融性能,因此特别适合在寒冷地区使用。

Summarized as follows: powder paint is a kind of decorative effect like marble, granite. It is mainly made of natural stone powder of various colors. Lacquer decoration of the building, has a natural real natural color and beauty to people with elegant, harmonious and solemn. It is suitable for indoor and outdoor decoration of all kinds of buildings. Especially for decoration on curved buildings, it can receive vivid, realistic and natural effects. Stone with fire prevention, waterproof, acid and alkali resistance, pollution. Non toxic, tasteless, strong adhesive force, never fading and so on, can effectively prevent the environment from erosion of buildings and prolong the life of buildings. Because of good adhesion and resistance to freezing and thawing, the real stone paint is especially suitable for use in cold areas.

真石漆施工简便,易干省时,施工方便等优点。

Stone construction is simple, easy to dry, the advantages of convenience.

1. 涂层硬度真石漆的涂层施工干固后十分坚硬,指甲不能抠动。一般的真石漆如果在良好的天气情况下施工三天后仍能用指甲抠动,应视为涂层太软。原因主要是选择的乳液不恰当。它们在制备真石漆时,采取与制备乳胶漆相同的乳液,这就导致真石漆配方中的乳液含量较低,成膜时因大量砂石的存在使得涂层不够紧密。经涂料研发人员研究:用于真石漆制备的乳液的粘结强度不应低于3MPa,最低成膜温度不应低于15摄氏度。较高的最低成膜温度可能会造成在气温较低时不易成膜的缺点,可以通过适当多加成膜助剂的方法来解决。成膜助剂在涂层干燥后可完全挥发,一般不会影响涂膜的性能。真石漆选择的是粘结力较高的、最低成膜温度也较高的复合乳液,这从根本上解决了涂层太软的问题。

1. the hardness of the coating coating construction of lacquer dries very hard, can not pull the nails. The general construction in three days if various weather conditions are good under the fingernails can still move, should be regarded as a soft coating. The main reason is that the selected emulsion is not appropriate. When preparing the true stone lacquer, they take the same emulsion as the preparation of the latex paint, which leads to the lower emulsion content in the real stone paint formula, and the coating is not close enough because of the existence of a large amount of sand. Research by paint developers: the bonding strength of the emulsion used for genuine stone paint should not be lower than 3MPa, and the minimum film forming temperature should not be less than 15 degrees Celsius. The higher the minimum film forming temperature may cause the difficulty of film formation at low temperature, which can be solved by proper addition of film auxiliaries. The film builder can completely volatilize after drying, and generally does not affect the performance of the coating. The choice of genuine stone paint is the composite emulsion with high cohesive force and the lowest film forming temperature. This fundamentally solves the problem of too soft coating.

2.涂层抗水性良好,稳定着色,不发白,无色差有些真石漆涂层在每次下雨以后,都会发白,涂层变得疏松,而在雨停后,经太阳一晒,涂层又恢复原来的颜色。其实,这是由于涂层的耐水性不好、吸收了水分所引起的,配方原因是选用的丙烯酸乳液在合成时需加入表面活性剂,有些厂家为了增加乳液的稳定性,所用的表面活性剂大大超量;有些厂家在制备真石漆时加入羧甲基纤维素、羟乙基纤维素等物质作为增稠剂,以及加入苯甲酸钠作为防腐剂。这些物质都是水溶性的或亲水的,涂料成膜后留在涂层中,就大大降低了涂层的耐水性能。实验说明,将纯丙乳液与石英砂混合,不加任何助剂,喷涂形成的涂层,其吸水率为0.42%;而在上述涂料的基础上加入0.4%羟乙基纤维素,吸水率上升至4.3%。由于真石漆的涂层较厚,一旦吸收了水份后,不容易在较短的时间内释放出来,因此造成外观发白,涂层内部疏松的结果。传化真石漆ESE选用的成膜助剂:有机硅改性丙烯酸酯乳液(硅丙乳液)。

2. coating water resistance is good, stable coloring, not white, no color difference, some true stone coating after each rain, will be white, coating becomes loose, and after the rain stopped, the sun, the coating and the original color. In fact, this is due to the poor water resistance of the coating, the absorption of water caused by the formulation reason is that the choice of acrylic emulsion in the synthesis of surfactant, some manufacturers in order to increase the stability of the emulsion, the surface active agent is greatly exceeded; some manufacturers are adding carboxymethyl cellulose in the preparation of real stone lacquer. Hydroxyethyl cellulose and other substances are used as thickeners, and sodium benzoate is added as preservative. All of these substances are water-soluble or hydrophilic. After coating is deposited on the coating, the water resistance of the coating is greatly reduced. The experiment shows that the water absorption rate of the spray formed coating is 0.42% without any additives, and the water absorption rate rises to 4.3% by adding 0.4% hydroxyethyl cellulose on the basis of the above coating. As the coating of the stone paint is thicker, once the water is absorbed, it is not easy to release in a short time, so the appearance is white and the inner coating is loose. Coalescents truestonepaint selection: ESE - silicone modified acrylate emulsion (emulsion).
