Abstract

The invention provides scouring-resistance high-performance outer wall emulsion paint and a preparation method thereof. The scouring-resistance high-performance outer wall emulsion paint comprises the following components in percentage by weight: 10 to 20 percent of water, 0.1 to 0.3 percent of preservative, 0.5 to 1 percent of wet dispersant, 0.4 to 0.8 percent of defoaming agent, 20 to 30 percent of rutile titanium white, 6 to 12 percent of calcium carbonate, 6 to 12 percent of barium sulfate, 2 to 5 percent of nano scratch resisting agent, 1 to 3 percent of polytetrafluoroethylene wax, 25 to 40 percent of fluorocarbon emulsion, 1 to 2 percent of glycol, 1 to 3 percent of coalescent, 1 to 2 percent of polyurethane thickening agent and 1 to 2 percent of leveling agent. The invention overcomes the defects that the durability, the scouring resistance and the protectiveness to a base material are not enough in the prior art and has the advantages of excellent covering power, adhesive force, weather resistance and scouring resistance, more than one hundred thousand times of scouring-resistance times as well bright and durable paint film.

Description

technical field [0001] The invention belongs to a paint composition, in particular to a scrub-resistant high-performance latex paint for exterior walls. The invention relates to latex paint made by applying a special nano anti-scratch agent, polytetrafluoroethylene wax and fluorocarbon emulsion and a preparation method thereof. technical background [0002] At present, there are many kinds of exterior wall latex paints on the market, but they all generally have the shortcomings of insufficient durability and scrub resistance, and insufficient protection of the substrate. Although some products have solved the problem of poor scrubability, such as CN200410006221.6, they can only be used for interior walls because they have used anatase titanium dioxide and lithopone and styrene-acrylic with poor weather resistance. Wipe other high-performance exterior wall latex paints with strong weather resistance. Contents of the invention [0003] In order to overcome the shortcomings...
