Interior wall coating with lasting fragrance and preparation method thereof

The invention discloses an interior wall coating with lasting fragrance. An EO group in used polymer latex and hydrophilic perfume form a strong hydrogen bond, so that the perfume is slowly released.The interior wall coating can keep fragrance for a long time and does not need to use a perfume carrier. An EA monomer and other polymerized or non-polymerized vinyl monomers are used in cooperation with the polymer latex prepared by using a nonionic emulsifier with the long EO number, so that a coalescing agent and an anti-freezing agent do not need to be added when the water-based coating is prepared. The fragrant coating is especially suitable for being used as a sleep-aiding and air-purifying coating in bedrooms, and is safe and non-irritant. 本发明公开了一种具有持久香味的内墙涂料，其使用的聚合物胶乳中的EO基团与亲水性香料形成强的氢键，使香料得到缓慢释放。该内墙涂料可以长时间留香且无需使用香料载体。通过使用EA单体和其它聚合或非聚合的乙烯基的单体，配合使用长EO数的非离子乳化剂制备的聚合物胶乳在制备水性涂料时不需要添加成膜助剂及防冻剂。该香味涂料尤其适合用作卧室中的助眠和空气净化涂料，安全无刺激。
