preparation example Construction

[0034] The preparation method of acrylic acid modified hydroxyfullerene is:

[0035] (1) Weigh a certain amount of fullerene and place it in a round-bottomed flask, add 98% concentrated sulfuric acid dropwise in an ice-water bath, and disperse it ultrasonically for 0.5-1h to obtain a dark green suspension solution, then vigorously stir in an ice-water bath Add distilled water dropwise and then add NaNO 3 , heated up to 100°C-120°C under the protection of an inert gas, stirred for 3-4h, cooled, stirred in an ice-water bath to obtain a tan solution, filtered, and the clear liquid was obtained;

[0036] (2) Use 3mol / L NaOH solution to adjust the pH value of the clear liquid obtained in step (1) to 10-12, so that a large amount of suspended matter gradually darkens in the solution, and finally becomes an opaque solution, and stands for 3-4h Make the precipitation complete, and use a centrifuge to centrifuge at 3500-5000r / min for 10-15min to obtain brown solid and brown liquid, th...

Embodiment 1

[0042] (1) Weigh 30 parts of acrylate oligomer, 15 parts of acrylic acid monomer, 3 parts of H-fullerene, 0.1 part of photoinitiator 1173, 0.02 part of leveling agent BYK-333, 0.1 part of dispersant SRE-4029 , 0.1 part of defoamer BYK1797, first add acrylate oligomer, acrylate monomer and modified fullerene into the reaction kettle, stir at 800r / min for 2 hours, and add leveling agent in turn during the continuous stirring process , defoamer, dispersant, and then add photoinitiator to make it evenly mixed, that is, to prepare a super wear-resistant light-cured coating based on fullerene;

[0043] (2) Apply the fullerene-based super-abrasive light-curable coating obtained in step (1) on the tinplate, and cure it to form a film under UV light to obtain a fullerene-based super-abrasive light-curable coating.

Embodiment 2

[0045] (1) Weigh 40 parts of acrylate oligomer, 24 parts of acrylic acid monomer, 4 parts of D-fullerene, 0.5 part of photoinitiator 184, 0.06 part of leveling agent BG2020, 0.3 part of dispersant SRE-4026X, 0.4 Defoamer BYK052, first add acrylate oligomer, acrylate monomer and modified fullerene into the reactor, stir at 1000r / min for 1h, add leveling agent, Foaming agent, dispersant, and photoinitiator are added to make it evenly mixed, that is, a super wear-resistant photocurable coating based on fullerene is prepared;

[0046] (2) Apply the fullerene-based super-abrasive light-curable coating obtained in step (1) on the tinplate, and cure it to form a film under UV light to obtain a fullerene-based super-abrasive light-curable coating.

Abstract

The invention belongs to the technical field of coatings, and specifically relates to a fullerene-based super wear-resistant light-cured coating and a preparation method thereof. The coating used for preparing the coating includes the following components in parts by weight: 100 parts of resin-based polymerized monomers, 0.1-1 part of photoinitiator, 0.02-0.1 part of leveling agent, 0.1-0.5 part of dispersant, 0.1-0.6 part of defoamer, 3-5 parts of modified fullerene, and the resin-based polymerized monomer includes the following Each component in parts by weight: 30-50 parts of acrylate oligomer, 20-40 parts of acrylate monomer. The polymeric elastomer in the coating used in the coating of the present invention is a mixture of acrylate oligomer and acrylate monomer, and modified fullerene has been added, and the modified fullerene can be uniformly dispersed in the coating system to play a role. To achieve long-term wear resistance, the prepared coating has higher wear resistance and scratch resistance, and can still maintain good wear resistance after long-term use.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a fullerene-based super wear-resistant light-cured coating and a preparation method thereof. Background technique [0002] Wear-resistant coatings are a new type of functional coatings with special functions. They have good wear resistance. They are usually coated on the surface of materials to improve the wear resistance of materials and prolong the service life of materials. In order to reduce the wear caused by the erosion of materials on equipment parts, a layer of wear-resistant material is coated on the surface of equipment parts to protect the base material of equipment parts. UV curable paint spray topcoat has been widely used in 3C electronic products to meet people's needs for product performance and decorative effects. Many manufacturers have been committed to wear-resistant and high-hardness UV-cured coatings. However, their wear-resistant properties are...
