Abstract

The invention provides waterborne gloss oil and a preparation method and application thereof. The waterborne gloss oil is prepared from, by weight, 35-55 parts of a waterborne hydroxy-acrylic dispersing body, 5-12 parts of a waterborne acrylate hardening emulsion, 12-20 parts of a water dispersible isocyanate curing agent, 0.5-1.5 parts of anti-UV auxiliaries, 1-3.5 parts of anti-scratch hand feeling auxiliaries and 20-30 parts of water. The waterborne gloss oil has the high hardness and high wet film thickness, the surface can be rapidly dried, the hardness can reach the 3H level, the good anti-scratch performance is achieved, the abrasion, damage and scratch probability are greatly lowered, the friction resistance frequency under the load of 500 g can reach 500 or more, the good appearance and glossiness are achieved, the comprehensive performance is good, particularly when the gloss oil is applied to a carbon fiber bicycle, the good scratch resistance is shown, and the high application value and the good application prospect are achieved.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a water-based varnish and a preparation method and application thereof. Background technique [0002] At present, the exterior coatings on carbon fiber bicycles are still mainly oil-based in the market, so, inevitably, the VOC emissions are large, and at the same time, they are harmful to the environment and human body. At present, water-based coatings use water as the dispersion medium instead of oily solvents and are gradually being widely used. The application of water-based coatings in the exterior coating of carbon fiber bicycles greatly meets the needs of manufacturers to pursue environmentally friendly and low-toxic coatings. [0003] However, compared with the same type of oil-based varnish, water-based coatings, especially water-based varnish, still have a certain performance gap, which is reflected in the hardness, wet film thickness, gloss, dryness, etc. of the same type of oil-...
