Embodiment 1

[0032] A wear-resistant water-based baking varnish, the production raw materials and their mass parts are as follows, including resin, resin aqueous solution and color paste; 9.5 parts, 10.1 parts of trimethylolpropane, 23.1 parts of adipic acid, 19.6 parts of 4-butanediol and 9.9 parts of butyl cellosolve; the aqueous resin solution includes 100 parts of water-soluble oil-free alkyd resin, 6.0 parts of dimethylethanolamine , 149.1 parts of deionized water and 50.2 parts of glass fiber; the color paste includes 89 parts of resin aqueous solution, 20 parts of metal particles and 70.1 parts of titanium dioxide. In this embodiment, the glass fiber is made of molten glass into glass balls with a diameter of 15 mm, and then heated and remelted to make very fine fibers with a diameter of 3-80 μm. The heating method is common knowledge and will not be repeated here.

[0033] Its manufacturing method comprises the following steps:

[0034] Step 1, preparation of water-soluble oil-fre...

Embodiment 2

[0046] The difference between this example and Example 1 is that the resin includes 24.9 parts of isophthalic acid, 14.9 parts of trimellitic anhydride, 10.5 parts of hexadecanyl succinic anhydride, 14.5 parts of trimethylolpropane, adipic acid 25.0 parts, 20.5 parts of 4-butanediol, 11.9 parts of butyl cellosolve; Resin aqueous solution comprises 100 parts of water-soluble oil-free alkyd resins, 7.9 parts of dimethylethanolamine, 1151.0 parts of deionized water, 60.8 parts of glass fibers; In the example, the glass fiber is made of molten glass into a glass rod with a diameter of 15 mm, and then reheated and remelted to make a very fine fiber with a diameter of 3-80 μm. The heating method is common knowledge and will not be repeated here. The color paste includes 95 parts of resin aqueous solution, 22 parts of metal particles and 70.1 parts of titanium dioxide. In step 1, raise the temperature to 210°C while stirring, keep it warm for 2 hours, and then add 9.9 parts of butyl ...

Embodiment 3

[0048] Resins include 20.0 parts of isophthalic acid, 12.5 parts of trimellitic anhydride, 9.8 parts of hexadecanyl succinic anhydride, 12.0 parts of trimethylolpropane, 24 parts of adipic acid, 19.8 parts of 4-butanediol, butyl solvent 1.8 parts of fiber agent; resin aqueous solution includes 100 parts of water-soluble oil-free alkyd resin, 7.6 parts of dimethylethanolamine, 150.2 parts of deionized water, 58.8 parts of glass fiber; color paste includes 93.2 parts of resin aqueous solution, 25 parts of metal particles and titanium White powder 73.5 parts. While stirring in step 1, raise the temperature to 205 degrees, keep it warm for 2 hours, and then add 10.4 parts of butyl cellosolve after cooling to below 100 degrees for dilution. Add 55.6 parts of glass fiber in step 2. In step 3, titanium dioxide was added into a grinder and ground for 1.2 hours to obtain nano titanium dioxide, and then 73 parts of nano titanium dioxide was added to the aqueous resin solution for mixin...

Abstract

The invention relates to the technical field of waterborne paint, and particularly discloses a wear-resisting waterborne stoving varnish. The waterborne stoving varnish is prepared from resin, a resinwater solution and color paste. The resin is prepared from isophthalic acid, trimellitic anhydride, n-hexadecylthiophene methyl succinic anhydride, trimethylolpropane, adipic acid, 4-butanediol and butylcellosolve. The resin water solution is prepared from water soluble oil free alkyd resin, dimethyl cholamine, deionized water and glass fiber; the color paste is prepared from the resin water solution, metal particles and titanium dioxide. The invention further discloses a method for producing the stoving varnish. By adopting the scheme, the wear resistance of the stoving varnish can be improved, the production process of the stoving varnish is simplified, and the production cost of the stoving varnish is lowered.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, and specifically discloses a wear-resistant water-based baking varnish and a manufacturing method thereof. Background technique [0002] Baking varnish is a new type of paint in furniture manufacturing. It has good non-stick properties, heat resistance, sliding properties, corrosion resistance, etc., and has good visual effects, and is widely used in high-end furniture. The method is: spray several layers of paint on a base that has been polished to a certain degree of roughness (usually a high-density board), and bake it at a high temperature to shape it. Although the existing baking varnish is wear-resistant, its technical level is relatively high, the process is relatively complicated, and the color transparency of the finished product is prone to be insufficient, so the price remains high, and the existing baking varnish furniture is very afraid of being bumped by hard objects ...
