Embodiment 1～ Embodiment 5

[0040] The formula proportioning of the elastic paint of table 1 embodiment 6~embodiment 10

[0041]

[0042] The preparation method of above-mentioned high weather resistance type feel elastic paint is:

[0043] (1) Stir the polyaspartic acid ester modified resin, the wetting dispersant and half of the mixed solution evenly;

[0044] (2) Add polytetrafluoroethylene wax powder and stir evenly at 1200-1500 rpm;

[0045] (3) Under the condition of 300-600 r / min, slowly add matting powder, elastic powder, hand feeling additives, nano pigments, rheological additives while stirring;

[0046] (4) Stir evenly under the rotating speed condition of 1200~1500 rpm;

[0047] (5) Add drier, leveling agent and the remaining mixed solvent, and stir evenly at 300-500 rpm.

[0048] Performance Testing

[0049] In order to compare the performance of the paints provided by the present invention, the following comparative examples were adopted.

Embodiment 6～ Embodiment 10

[0059] As an improved formula, add 2 to 4% of pure polyester resin, 0.5 to 2% of hardening and wear-resistant additives, and 2 to 5% of wax paste for modification.

[0060] Polyester resin (F1190 Feiyang Chemical)

[0061] Hardening and wear-resistant additives (450 Lubrizol)

Abstract

Belonging to the technical field of paint preparation, the invention provides an elastic handfeel paint composed of component A and component B. The component A comprises, by weight: 25-38% of polyaspartic ester modified resin, 0.1-0.3% of a dibutyltin dilaurate drier, 5-7% of matting powder, 2-5% of elastic powder, 2-10% of a handfeel assistant, 0.1-0.3% of a leveling agent, 1-2% of a wetting dispersant, 2-3% of a nano-pigment, 0.2-0.5% of polyfluortetraethylene wax powder, 0.5-1% of a rheological assistant, and 41-55% of a mixed solvent. The component B is an HDI type trimer curing agent. And the component A and the component B are in a weight ratio of 10:1-2. The elastic handfeel paint provided by the invention has good elasticity, excellent weather resistance that can reach over 1500 hours, salt fog resistance up to more than 300 hours, and heat-cold shock resistance up to over 200 hours. Meanwhile, the paint has excellent handfeel and wear resistance.

Description

technical field [0001] The invention provides a hand-feeling elastic paint, in particular to a hand-feeling elastic paint with high weather resistance, which belongs to the technical field of paint making. Background technique [0002] With the improvement of people's living standards, the requirements for the appearance of daily necessities are getting higher and higher, such as aluminum powder effect, crack effect, elastic feel effect, etc., especially some parts that are often touched by hands require spraying elastic feel paint, such as hair dryer handle, MP3 Cases, mice, mobile phone cases, binoculars, umbrella handles, etc. no longer require that kind of cold, rough, and blunt feeling, but make people feel a soft and smooth feeling. For this reason, elastic touch paint came into being. As the matt type PU elastic paint mentioned in the public document with the publication number CN102229782, the paint film has a rich hand feel and soft luster. The color-adding type el...
