摘 要：本文闡述了乳膠漆的定義，如何進行乳膠漆的配方設計，并進行了不同配方乳膠漆的調制，測定了它們的細度和耐洗刷度。
 通過改變聚苯乙烯-丙烯酸脂乳液（苯丙乳液）和重鈣、輕鈣使用量來改變乳膠漆的配方，從而得出影響細度和耐洗刷度的因素。在細度的測定實驗中，發現了重鈣、輕鈣的用量對乳膠漆的細度的影響：重鈣越多，細度越差；輕鈣越多，細度越好。在耐洗刷度的測定實驗中，通過JTX-II型建筑涂料耐洗刷儀的測定，得出乳液用量越多，耐洗刷性越好。
 最后得出了既滿足性能要求，原料用量又最少的乳膠漆配方：水150g，助溶劑5g，增稠劑5g，濕潤分散劑3.5g，防腐劑0.5g，消泡劑1g，成膜助劑3g，鈦白粉100g，重鈣75g，輕鈣125g；乳液140g。

Abstract: This article expounds the definition of latex paint, latex paint formula how to design and carry out the modulation of different paint formulations to determine their degree of fineness and abrasion.
 By changing the polystyrene - acrylic resin emulsion (acrylic emulsion) and the heavy Calcium, to change the use of light calcium emulsion formula to arrive at impact and abrasion degree of fineness of the factors. Determination of fineness of the experiment, found a heavy calcium light calcium content on the fineness of emulsion: Heavy Calcium more fineness worse; light calcium more fineness better. In the abrasion test of measuring the degree by JTX-II-type building coating abrasion instrument measured, obtained emulsion, the more the better scrub resistance.
 The conclusion that not only meet the performance requirements, raw materials has the least amount of latex paint formulations: Water 150g, cosolvent 5g, thickener 5g, wet dispersant 3.5g, preservatives 0.5g, defoamers 1g, coalescent 3g, titanium dioxide 100g, heavy calcium 75g, light calcium 125g; Emulsion 140g.
