背景技术
建筑装饰涂料应用于墙面装饰已有多年，产品和施工工艺都较成熟。如图1所示，目前大多数墙面装饰采用的多彩涂料施工工艺：①腻子(见图1-1，找平提高平整度)→②底漆(见图1-2，保护漆膜提高附着力)→③着色中间漆(见图1-3，提供遮盖力和效果)→④面漆(见图1-4，提供漆膜效果)→⑤面油(见图1-5，保护漆膜、提高耐污和耐水性)。该工艺共需要5道工序和至少5种材料，工序和耗用材料品种多从而在施工过程中效率相对会低些，耗用材料品种多导致耗损率偏高不利节约环保和提高效率。
为解决这个问题，本发明致力于研发出一种新的复合底涂，集腻子、底漆和中间着色漆的功能，将①-③施工工序集于一道，从而将5道工序减至3道，至少5种材料减至至少3种材料，施工过程就会省时、省工序和节约材料等优点。

进一步地，所述乳液选自苯丙乳液、纯丙烯酸乳液、硅丙乳液、氟碳乳液、环氧乳液中的一种或多种。
进一步地，所述防冻剂为有机醇类。
更进一步地，所述防冻剂选自乙醇、乙二醇、丙二醇中的一种或多种。
进一步地，所述金红石钛白粉的TiO2含量≥98％，筛余物(0.045mm筛孔)≤0.05。
进一步地，所述石英砂为精制石英砂，外观呈白色或近白色，SiO2≥99％，粒度为100-200目。
进一步地，所述大理石粉的白度≥90，粒度≥200目。
进一步地，所述滑石粉的白度≥85，粒度≥400目。
本发明的具有封闭、找平和中间着色的复合底涂中所用的乳液能增强漆膜柔韧性、粘结强度、抗裂性、耐水耐碱性、抗泛盐性和透水性；所用的纤维素醚、防冻剂、成膜助剂、润湿分散剂、增稠剂，给予成品良好的施工性、储存性、分散调色性和施工开放时间；所用的防腐防霉剂、PH调节剂给予漆良好的保护性；通过本发明的配方组成和制备方法所得的复合底涂能同时达到JG/T 157-2009《建筑外墙用腻子》R型、JG/T210-2018《建筑内外墙用底漆》外墙成膜Ⅱ型的要求，可实现腻子找平，底漆封闭，中间着色三道工序合三为一的施工方案，施工过程省时、省工序和节约材料。
