Embodiment 1~3

[0045] The preparation method of high weather resistance anti-sticking coating comprises the following steps:

[0046] Step 1, prepare the main agent: mix the resin, solvent 1 and solvent 2 added for the first time, stir evenly, then add defoamer and nano additives, disperse for 5 minutes, then slowly add anti-sedimentation agent and silicone oil, After dispersing for 3 minutes, add pigment 1, filler and pigment 2 in order, disperse at 850r / min for 10min, then increase the speed and disperse at 3000r / min for 20min, then reduce the speed to 1600r / min, then add the remaining Solvent 1 and the remaining solvent 2 can be continuously dispersed for 3 minutes; the mass parts of each component in Step 1 of Examples 1-3 are shown in Table 1.

[0048]

[0049]

[0050] Step 2: mix the main agent and the curing agent uniformly to prepare the paint, and see Table 2 for the mass parts ratio of the main agent and the curing agent in Step 2 of Examples 1-3.

Abstract

The invention discloses a high-weather-resistance anti-sticking coating and a preparation method thereof. The high-weather-resistance anti-sticking coating is prepared from a main agent and a curing agent, wherein the ratio of the main agent to the curing agent is (95-105): 1. (35-45), the main agent is from following components in parts by weight: 40-60 parts of resin; 2-6 parts of a solvent I; 0.5-2.5 parts of a solvent II, 1-3 parts of a nano auxiliary agent, 0.1-0.3 part of an antifoaming agent, 4-8 parts of silicone oil, 0.1-2 parts of an anti-settling agent, 10-30 parts of a pigment I, 5-35 parts of a filling material, and 0.1-1 part of a pigment II, and the curing agent is an aliphatic isocyanate curing agent. Organic silicon modified hydroxyl acrylic resin is selected as matrix resin, so that the performance complementation of two resins can be realized, the hydrophobicity and oleophobicity are improved, and the wiping performance and anti-sticking performance of an anti-marking pen are improved.

Description

technical field [0001] The invention belongs to the technical field of anti-sticking coatings, and in particular relates to a highly weather-resistant anti-sticking coating and a preparation method thereof. Background technique [0002] In order to let more people understand their products, some merchants will paste advertisements on poles or buildings, which not only seriously affects the appearance of the city, but also causes visual pollution. The anti-stick coating has a strong anti-stick effect , Anti-graffiti ability; but internally, it will be tightly attached to the wall or the surface layer of the construction. [0003] After the anti-adhesive coating is applied on the surface, small advertisements with paste, glue or self-adhesive adhesives can not be pasted or even if they are strongly stuck, they will fall off when the wind blows and are not easy to stick. Get scribbled on. In addition, it can also prevent uncivilized actions, such as graffiti, random pasting, ...
