Embodiment 1

[0027] A T-ZnO whisker quick-drying modified alkyd resin enamel was prepared. Pour 5‰ (weight fraction) of T-ZnO whiskers prepared by chemical method into 2 times the weight of petroleum ether, stir for 5 minutes, disperse in an ultrasonic instrument for 10 minutes, and distill the petroleum ether in a distillation bottle. After dissolving 1% silane coupling agent KH-550 of the weight of T-ZnO whiskers with petroleum ether that is 1 times the volume of T-ZnO whiskers, pour the dispersed T-ZnO whiskers into it after simple stirring, and then ultrasonically Coupling treatment in the instrument for 10 minutes to obtain T-ZnO whisker paste. According to the dosage ratio of the modified alkyd resin paint formula, 60 parts of modified alkyd resin (base material), T-ZnO whisker paste, pre-mixed, ground, filtered coloring and body pigment (21 parts) , additives (6 parts) and solvent No. 200 mineral spirits (12 parts) are mixed together in a mixing tank, and then ground by a three-rol...

Embodiment 2

[0038] A T-ZnO whisker iron red alkyd primer was prepared. Pour 5% (weight fraction) of T-ZnO whiskers prepared by chemical method into ethanol whose weight is twice the amount, stir for 5 minutes, disperse in an ultrasonic instrument for 10 minutes, and distill the ethanol out in a distillation bottle. After dissolving 1% titanate 402# coupling agent of the T-ZnO whisker weight with acetone that is 1 times the volume of the T-ZnO whisker, pour the dispersed T-ZnO whisker into it and stir briefly, and then ultrasonically Coupling treatment in the instrument for 10 minutes to obtain T-ZnO whisker paste. According to the dosage ratio of the modified alkyd resin paint formula, 40 parts of modified alkyd resin (base material), T-ZnO whisker paste, pre-mixed, ground, filtered iron red pigment (20 parts) and The extender pigment (21 parts), the additive (6 parts) and the solvent (12 parts) are mixed together in a mixing tank, and then ground by a three-roll mill until the fineness ...

Abstract

A high wear resistance and static-free antibiosis paint relates to an oil paint and takes natural resin or synthesis resin as the base; pigment, filler, four-footed zinc oxide T-ZnO crystal whisker treated with dispersion and coupling, charging material and addition agent and solvent are then added, finally the paint is manufactured by mechanical processing; the isotacticity of the crystal whisker is more than 90 percent, the foot length-diameter ratio of the T-ZnO crystal whisker is 16-20, the foot length is 40-50 Mum and the consumption of the T-ZnO crystal whisker accounts for 0.5-5 percent of the total weight of paint. Compared with corresponding similar paints, the paint has simple and unique preparation process, excellent quality, stronger adherence, outstanding anticorrosive performance and mechanical property and preparation cost not more than the corresponding paint.

Description

technical field [0001] The invention relates to an oil-based paint, in particular to a highly wear-resistant, antistatic and antibacterial paint. Background technique [0002] Common traditional paints (oil-based paints) in the market are made of natural resin or synthetic resin as the base material, and then various pigments, various fillers, auxiliary solvents are added and manufactured through mechanical processing. Some resins have poor wear resistance and some have friction in the use environment, which often causes the paint film to wear out and lose its function; on the other hand, because polymer materials are mostly insulating materials, static electricity is often generated in a dry environment. There will be greater harm, even danger; and due to the humid and hot environment, etc., the paint film will be overgrown with enzymes and bacteria. [0003] Oil-based coatings are mostly used for the protection and decoration of mechanical equipment, metal products / compon...
