摘要
与现行的水包水多彩涂料相比,水包砂多彩涂料不需要造型层,可一次成型立体感强的仿花岗岩效果,但是由于基础漆中加入了大量的砂子,对其性能造成较大的不利影响。本文就水包砂多彩涂料的制备进行实验研究,通过对保护胶的用量、润湿剂的种类及用量、纤维素醚种类及用量进行平行实验,在保护胶GS用量为10%~12%、润湿剂399用量为0.4%~0.6%、纤维素250HHBR用量为1.2%~1.4%时,得到了抗渗色性、耐水白性和稳定性优异的水包砂多彩涂料。
Compared with the commonly used water-in-water multi-color coatings,the water-in-sand multicolor coatings can form a three-dimensional granite-like effect without a moulding layer in a single coat.However,due to the addition of a large number of sand in the basecoatings,which caused a greater adverse impact on its performance.In this paper,the preparation of water-in-sand multicolor coatings was studied experimentally.Parallel experiments were carried out on the influence of amount of protective glue,types and dosages of wetting agents,types and dosages of cellulose ethers.When the dosage of protective glue GS was 10%-12%,wetting agent 399 was 0.4%~0.6%,and the dosage of cellulose 250HHBR was 1.2%-1.4%,respectively,the sand-in-water multicolor coatings provided excellent bleeding resistance,blushing resistance and stability.
