Description
Technical Field
The application relates to the field of brake pads, in particular to UV (ultraviolet) jet printing ink for a brake pad, and a preparation method and application thereof.
Background
The brake pad of the automobile is the most critical safety part in a brake system of the automobile and is used for decelerating and stopping the automobile, the brake pad is generally composed of a steel plate, an adhesive heat insulation layer and a friction block, ink is generally directly sprayed on a friction material, and the friction material is generally composed of an adhesive, reinforcing fibers, a filling material and a regulating material. The brake pad is manufactured and then is printed on the friction material, and the traditional technology adopts a silk screen printing or pad printing mode to print names, models, batch numbers, identification codes and the like on the brake pad, but the traditional printing mode has the defects of low printing precision, inaccurate printing position, low efficiency, complex plate making period and the like. When the UV jet printing is adopted, the thickness of the UV jet printing ink film is not equal to that of the silk screen printing, and the problems of uneven printing result, weakened protective layer effect, reduced friction performance and the like can be caused.
Content of the application
The present application aims to solve at least one of the technical problems existing in the prior art. Therefore, the application provides UV jet printing ink for a brake pad, which comprises the following components in parts by weight:
wherein the dispersant is selected from Solsperse series of dispersants;
the UV oligomer is aliphatic polyurethane UV light-cured resin;
the UV monomer comprises at least one of acrylate UV monomer, vinyl ether monomer and polyamide UV monomer.
More specifically, in the technical proposal, the Solsperse series dispersant comprises Solsperse36000,
At least one of Solsperse39000 and Solsperse 35000.
Further specifically, in the above technical scheme, the aliphatic polyurethane UV light curing resin comprises at least one of NeoRad U-20-12T, neoRad U-24-25T and NeoRad U6282.
Further specifically, in the above technical solution, the acrylic acid ester UV monomer includes tetrahydrofuran acrylic acid ester and/or diethylene glycol diacrylate; the vinyl ether monomer comprises vinyl pyrrolidone and/or vinyl oxyethoxy 2 ethyl acrylate; the polyamide-based UV monomer comprises N, N-dimethylacrylamide and/or diethylacrylamide.
Further specifically, in the above embodiments, the photoinitiator includes at least one of TPO, TPO-L, 819 and 184.
Further specifically, in the technical scheme, the UV jet printing ink further comprises 0.01-1 part by weight of surfactant, wherein the surfactant comprises at least one of BYK-3500, BYK3510 and BYK-377.
Further specifically, in the technical scheme, the UV jet printing ink further comprises 0.1-1.5 parts of anti-settling agent by weight, wherein the anti-settling agent comprises AEROSIL A200 and/or AEROSIL A300.
Further specifically, IN the technical scheme, the UV jet printing ink further comprises 0.05-0.5 part of heat stabilizer by weight, wherein the heat stabilizer adopts Omnistab IN510.
The application also provides a preparation method of the UV jet printing ink for the brake pad, which comprises the step of mixing the raw material components of the UV jet printing ink in proportion.
The application also provides application of the UV jet printing ink to a brake pad.
Compared with the prior art, the embodiment of the application has the following beneficial effects:
the application adopts the low-viscosity UV monomer, is favorable for reducing the viscosity of the whole formula, can increase the content of titanium dioxide under the formula, and fills the defect that the film thickness of the jet printing ink is inferior to that of silk screen printing through the synergistic cooperation of the resin, the monomer and the dispersing agent, thereby improving the whiteness and the hiding power of the ink and solving the problems of low whiteness, poor hiding power and the like of the UV white ink of the brake pad in the prior art.
