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.
