水性聚氨酯在色浆中的应用

来源:      2021-9-6 15:21:09      点击:
水性聚氨酯涂料,即以水性聚氨酯为主要原料生产的水性聚氨酯涂料,由于采用水作为分散体系,具有无毒、无臭、不易燃的特点,而且水性聚氨酯涂料具有良好的柔韧性和耐磨性、耐化学性和耐久性,因此,自20世纪60年代以来,水性聚氨酯涂料的发展趋势一直是人们关注的焦点,水性聚氨酯广泛应用于水性木器涂料、橡胶和塑料涂料、各种防水涂料、防腐涂料、纺织涂料、皮革涂料、印刷油墨、合成橡胶,特别是汽车内饰、建筑橡胶,甚至水性聚氨酯也用于新能源锂电池的电解反应。
Waterborne polyurethane coatings are water-borne coatings produced with water-borne polyurethane as the main raw material. Since water is used as a dispersion system, it is non-toxic, odorless, and not easy to burn. In addition, water-borne polyurethane coatings have excellent flexibility, abrasion resistance, chemical resistance and durability. Therefore, since the 1960s Waterborne polyurethane has been widely used in water-borne wood coatings, rubber-plastic coatings, waterproof coatings, anticorrosive coatings, textile coatings, leather coatings, printing inks, synthetic adhesives, especially automotive interior rubber, building rubber, and even water-borne polyurethane are also used in new energy lithium battery electrolysis.



有各种各样的水性聚氨酯涂料,还有客户需要的水性聚氨酯涂料色浆,所以,经常有客户问恒天新材料有聚氨酯色浆吗?专业而熟练的销售人员会先告诉客户有配套的聚氨酯漆糊,并会询问客户的应用情况,对颜色的要求,如木器漆聚氨酯漆糊需要良好的耐温性,耐酸耐碱性好!不能有黄变,色浆中颜料的性能是聚氨酯涂料颜色性能的保证!
Water-borne polyurethane coating has a wide range of applications, customers need to support the water-borne polyurethane coating coloring water-borne slurry, therefore, often have customers ask whether Hengtian Hefei water-borne polyurethane slurry? Professional and skilled sales staff will first tell the customer has a complete set of polyurethane paint and will carefully ask the customer. USERS, color requirements, such as wood paint polyurethane and need good temperature resistance, acid and Alkali Resistance! Can Not yellowing, the color paste in the pigment performance is to ensure the color performance of polyurethane paint the key!
随着塑料制品的广泛开发,为了延长塑料制品的使用寿命,工程师们在材料表面增加了一层涂层。选用聚氨酯涂料作为最合适的涂料,同时配套的聚氨酯色浆的颜色也需要考虑,耐候性能优越!
With the widespread development of plastic products, in order to extend the service life of plastic products, engineers add a layer of coating on the surface of the data, polyurethane coating is selected as the most appropriate coating, and matching polyurethane paste, color needs to consider the superior performance of weather resistance!
除了在选用聚氨酯浆料时要注意涂料的使用要求外,还有安全要求也需要涂料配方工程师在选用浆料色时足够注意!不含重金属,不含一些违禁微量有毒物质,在出口产品中使用的涂料,更应注意的是聚氨酯浆料是否符合北美或欧洲的安全标准!这也是一个很重要的选择条件!
In addition to the polyurethane color paste in the selection of the application of paint requirements, there are also safety requirements that need paint formulation engineers in the selection of color paste enough to pay attention to! North American or European standard of safety! This is also a very important choice.
在选择第三元素聚氨酯色浆时,要选择高固含量和高色浓度的色浆品种,不应选择价格低廉的色浓度过低的聚氨酯色浆,要保证色浆的添加尽可能少的原则,以确保颜料不会添加过多的色浆而造成破坏!
When choosing the polyurethane paste of the third element, we should choose the paste varieties with high solid content and high paste concentration, and should not choose the polyurethane paste with low cheap paste concentration. We should take the principle of ensuring that the amount of paste added is as small as possible to ensure that the paint will not be damaged by excessive addition of paste!
