Embodiment Construction

[0026] The present invention will be further described below in conjunction with embodiment.

[0027] The parts by weight of the highly hydrophobic anti-pasting advertising paint are as follows:

[0028] 250 parts of water

[0029] Thickener 3.0 parts

[0030] AMP95 1 part

[0031] Dispersant 2.5 parts

[0032] Defoamer 2.0 parts

[0033] Pigment and filler 520 parts

[0034] 10.5 parts of surface hydrophobic anti-adhesion additive

[0035] Silicone-containing styrene-acrylic emulsion 210 parts

[0036] 1 part preservative

[0037] Among them, the gradation ratio of pigments and fillers is 1 part of 1200 mesh diatomite, 1 part of 800 mesh quartz powder, and 1.3 parts of R706 titanium dioxide; the emulsion uses silicon-containing styrene-acrylic emulsion, and its average particle size is 130-160nm. It is 38%~40%, the viscosity is 50~500mPa.s, and the silicon content is 2~4%.

[0038] The KU viscosity of the finished coating is 95KU, and the lotus leaf effect can be obs...

Abstract

A high hydrophobic anti pasting poster paint, which is characterized in that the coating includes following components, weight parts of each is: water 20-40, thickening agents 0.1-3, AMP 95 0.1-0.5, dispersant 0.2-2, defoamer 0.1-0.5, color filling agent 20-50, hydrophobic surface anti pasting agent 0.1-0.5, emulsion 10-40, film-forming additive 0-2, preservative agent 0.1-1. the color filling agent is composed of diatomite or calcium carbonate matching with quartz powder and titanium dioxide and mixing, wherein the weight ratio of diatomite or calcium carbonate: quartz powder: titanium dioxide is 1: 0.5-5.5: 1-5. The present invention is provided with characteristics of high surface hydrophobic nature and surface anti pasting ability after film-forming, not easy to doodle or covered by sewerage or other coatings, and not easy to be pasted by common advertisement sticker with gum in the back, stable property, simple production process and convenient for construction.

Description

technical field [0001] The invention relates to a coating, in particular to a highly hydrophobic and anti-sticking advertising coating. Background technique [0002] In cities and rural areas, it is common to see outdoor advertisements with large text brushes. These advertisements are often covered by graffiti or pasted small advertisements, which greatly affect the appearance of cities and towns and bring great troubles to urban management. Urban management or The company needs to spend manpower and material resources to clean up and repaint the advertisements. [0003] Although fluorocarbon coatings can also provide anti-adhesive and hydrophobic properties, due to their low binding force, they are difficult to cure at room temperature, resulting in difficult construction, high cost and limited application. Contents of the invention [0004] The purpose of the present invention is to provide a film with strong surface hydrophobicity and surface anti-adhesion, which is no...
