preparation example Construction

[0046] The preparation method of described embodiment 1-4 is as follows:

[0047] Step 1, taking each component according to the above-mentioned raw material ratio;

[0048] Step 2, adding water-based acrylic resin and water-based polyester resin into the reactor, at a speed of 400-600rpm, adding film-forming aids and pH regulators in turn, and stirring for 5-10min;

[0049] Step 3, add deionized water, defoamer, wetting agent, and leveling agent to the reactor in sequence, and stir at a speed of 400-600rpm for 5-10min to obtain a paint slurry, which is checked with a scraper to see if there is any Shrinkage cavity, if there is stirring at a speed of 800-1000rpm for 10-15min, then proceed to step 4;

[0050] Step 4, at a rotating speed of 600-800rpm, add amino resin, blocked isocyanate, and self-made color paste in sequence, stir for 15-20min, and filter to obtain the gloss-free high-temperature baking finish for the shared bicycle.

[0051] The performance testing results o...

Abstract

The invention relates to the technical field of coatings and specifically discloses a glazing-free high-temperature baked finishing coat for a sharing bicycle and a preparation method thereof. The finishing coat contains the following components in parts by weight: 15-25 parts of water-based acrylic resin, 15-25 parts of water-based polyester resin, 2-3 parts of pH regulator, 0.5-1 part of de-foaming agent, 10-15 parts of coalescing agent, 0.2-0.5 part of wetting agent, 0.2-0.5 part of flatting agent, 25-35 parts of deionized water, 5-7 parts of amino resin, 1-3 parts of closed isocyanate and 5-10 parts of color paste. The coating technology according to the invention becomes a twice-coating twice-baking technology; the production efficiency is increased, the energy consumption is reduced, the cost is lowered and the VOC emission is reduced; the finishing coat after being baked has the effect of the paint film after being glazed and the weather fastness, glossiness and fullness all are comparable with those of the oil paint.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a gloss-free high-temperature baking finish for shared bicycles and a preparation method thereof. Background technique [0002] As we all know, China has always been a big country in bicycle production and retention. After the reform and opening up, the number of domestic bicycle manufacturing and sales ranks among the top in the world. The painting of the bicycle plays a decisive role in the quality and decorative effect of the bicycle. Since the promulgation and implementation of the first volatile organic compound (VOC) law in California in 1966, countries have raised the level of laws and regulations to strictly control VOC emissions and limit the production and use of high-VOC paint products. Water-based paint has become the mainstream direction of modern paint industry development because of its low VOC content and energy saving. In North America, water-based industrial...
