Research on Anti-Cracking Performance of Interior Wall Latex Paint
The effects of sericite,talcum,calcined kaolin and coalescing agent on covering power,anti-cracking performance and other properties of interior wall latex paint film were researched and analyzed.The result showed that on the basis of cost saving,8%talcum and 12%calcined kaolin can meet requirement of contrast ratio of the standard GB/T 9756-2018 super grade.Compared with fluffy calcined kaolin,laminar calcined kaolin is more helpful in improving cracking performance of the film.The film-forming performance at low temperature and stain resistance of the film are satisfying when the dosage of coalescing agent is 1.2%.With optimized solution above,not only the cracking performance of the interior wall latex paint can be improved,but also the cost of raw materials can be controlled,which improves customer satisfaction.
