Problems solved by technology

[0003] However, as people have higher and higher requirements on the performance of wall paints, wall paints that can prevent surface pollution (especially oil and water repellency) for a long time under severe environmental conditions are required. Therefore, the existing acrylic wall paints The topcoat can no longer fully meet people's requirements
[0004] To date, no acrylic wall paint has been produced in the prior art with enhanced oil, water, and scrub resistance to resist surface contamination for extended periods of time under harsh environmental conditions.

Embodiment 1

[0043] Embodiment 1: the acrylic wall paint that has added fluorocarbon surfactant

[0044] (I) Preparation

[0045] Prepare the acrylic wall paint of the present invention according to the following steps, and the formula is shown in Table 1 below.

[0046] 1. Weigh water according to the recipe.

[0047]2. Slowly add a certain amount of hexanediol and thickener Natrosol250HBR under low-speed stirring at 500rpm until the thickener is completely dissolved.

[0048] 3. Keep stirring at low speed, add antifoaming agents Tego Foamex 800 and Orontan 1124, and continue stirring for 10 minutes. Then put in heavy calcium and titanium dioxide, turn to 2000rpm high-speed stirring, until dispersed to a fineness of less than 50μm.

[0049] 4. Switch to 500-600rpm low-speed stirring, add film-forming aid Texanol and fluorocarbon dispersant FSO-100, stir evenly, then add Primal AC-261 resin, covering polymer Ropaque-E, dispersant Triton X-405 , thickener Acrysol RM-220NPR and water, ...

Embodiment 2

[0067] Embodiment 2: Added the propylene of fluorocarbon surfactant, polytetrafluoroethylene micropowder and poly(ethylene glycol ether) dispersant acid wall paint

[0068] (I) preparation

[0069] Prepare the acrylic wall paint of the present invention according to the following steps, and the formula is shown in Table 4 below.

[0070] 1. Weigh water according to the formula.

[0071] 2. Slowly add a certain amount of hexanediol and thickener Natrosol250HBR under low-speed stirring at 500rpm until the thickener is completely dissolved.

Abstract

The invention provides an acrylic coating composition with enhanced oil and water resistance and scrub resistance, which comprises the following components in total weight: 20 to 60 weight portions of acrylic latex, and 0.05 to 1.0 weight portion of fluorocarbon surfactant. The invention also provides a method for preparing the acrylic coating composition with the enhanced oil and water resistance and the scrub resistance, which comprises the step of mixing 0.05 to 1.0 weight portion of the fluorocarbon surfactant, 0.05 to 1.0 weight portion of polyethyleneglycol ether dispersant, 0.1 to 5.0 weight portions of polyfluortetraethylene micro powder and 20 to 60 weight portions of the acrylic latex to obtain the acrylic coating composition with the enhanced oil and water resistance and the scrub resistance.

Description

technical field [0001] This invention relates to improved acrylic wall paints. In particular, it relates to an acrylic coating composition having enhanced oil and water repellency and scrub resistance, and a method for preparing the acrylic coating composition having enhanced oil and water repellency and scrub resistance. Background technique [0002] Existing acrylic emulsions have been widely used in wall paints (comprising exterior wall paints and interior wall paints) because of their advantages such as water resistance, scrub resistance, pollution resistance, and aging resistance. Common acrylic emulsions include styrene-acrylic emulsions, pure acrylic emulsions, silicon-acrylic emulsions, etc., which are used in the preparation of various coatings such as exterior walls and interior walls to meet the corresponding product performance requirements and comprehensive performance requirements for different uses. The mainstream of paint (latex paint) base material. [000...
