preparation example Construction

[0035] In addition, the present embodiment also provides a method for preparing windshield rubber paint, which includes the following steps:

[0036] S1, the preparation of the first component:

[0037] In the container, 60-70 parts of polyester polyol resin, 20-30 parts of rutile titanium dioxide and 0.6-1.0 parts of anti-sedimentation agent are mixed and stirred evenly, ground to a fineness of less than 15 microns, and then Add 2-3 parts of ultraviolet absorber, 2-3 parts of anti-sticking and stain-resistant surface additives, 0.3-0.5 parts of leveling agent, and 0.2-0.5 parts of dispersant in proportion, and stir again to obtain the first component. During the preparation process, the container can be cleaned with conventional solvents, such as butyl acetate solvent. Wherein, the polyester polyol resin includes 20%-25% of polycaprolactone polyol and 75%-80% of linear polyester resin in terms of mass percentage.

[0038] S2, the preparation of the second component:

[003...

Embodiment 1

[0056] The raw material of the windshield rubber paint includes the first component and the second component with a mass ratio of 1:1. The first component includes in parts by weight: 60 parts of polyester polyol resin, 20 parts of rutile titanium dioxide, 2 parts of ultraviolet absorber, 2 parts of anti-sticking and stain-resistant surface additives, 0.3 parts of leveling agent, dispersant 0.2 parts and 0.6 parts of anti-settling agent, wherein the polyester polyol resin comprises 20% of polycaprolactone polyol and 80% of linear polyester resin by mass percentage. The second component is polyester modified aliphatic isocyanate resin.

[0057] The preparation method of the windshield rubber paint: prepare the first component according to the parts by weight, then add the polyester polyol resin, rutile titanium dioxide and anti-sedimentation agent into the first container and stir evenly, and grind to The fineness is less than 15 microns, then add UV absorber, anti-adhesive an...

Embodiment 2

[0059] The raw material of the windshield rubber paint includes the first component and the second component with a mass ratio of 1:1. The first component includes in parts by weight: 65 parts of polyester polyol resin, 28 parts of rutile titanium dioxide, 2.2 parts of ultraviolet absorber, 2 parts of anti-adhesive and anti-fouling surface additives, 0.3 parts of leveling agent, dispersant 0.5 part and 0.8 part of anti-sedimentation agent, wherein, polyester polyol resin comprises polycaprolactone polyol 25% and linear polyester resin 75% by mass percentage, and this linear polyester resin is the polyester modified by fluorosilicon ester resin; UV absorber is benzotriazole; anti-adhesive and anti-fouling surface additives include polytetrafluoroethylene and silicone; leveling agent is fluorocarbon modified polyacrylate leveling agent; dispersant is high Molecular polyurethane and anti-settling agent are fumed silica. The second component is polyester modified aliphatic isocya...

Abstract

The invention provides a rubber paint for a windshield and a preparation method thereof, belonging to the field of paint coatings. The rubber paint for the windshield comprises a first component and a second component in a mass ratio of 1: 1, wherein the first component comprises, by weight, 60 to 70 parts of polyester polyol resin, 20 to 30 parts of rutile titanium dioxide, 2 to 3 parts of an ultraviolet ray absorber, 2 to 3 parts of an anti-adhesion anti-fouling surface auxiliary agent, 0.3 to 0.5 part of a leveling agent, 0.2 to 0.5 part of a dispersing agent and 0.6 to 1.0 part of an anti-settling agent; the second component is polyester modified aliphatic isocyanate resin; and the polyester polyol resin comprises, by weight, 20 to 25% of polycaprolactone polyol and 75 to 80% of linear polyester resin. The rubber paint for the windshield has greatly improved weatherability, good elasticity and high elongation. The preparation method comprises a step of uniformly mixing the first component and the second component. The method is simple and is easy to operate.

Description

technical field [0001] The invention relates to the field of paints and coatings, in particular to a windshield rubber paint and a preparation method thereof. Background technique [0002] As we all know, as a decorative and protective windshield rubber paint, its performance is closely related to the composition of the paint. To achieve a paint film with good performance on the rubber surface, it is very important to choose resin raw materials that match the elasticity and hardness of the rubber material, otherwise It is difficult to meet the requirements of windshield rubber for bending flexibility during operation and use. Windshield rubber paint uses isocyanate as a curing agent, which reacts with the resin in the main agent during the curing process to form an elastic paint film that adheres to the rubber surface. In fact, the resin and curing agent in the formula are the main components of the whole formula and play a decisive role in the performance of the product. ...
