Embodiment 1

[0033] The preparation process method of a kind of durable car paint provided by embodiment 1 is as follows:

[0034] A preparation process of durable automobile paint, the first step is to mix 80g of microgelled acrylic resin, 0.4g of HDI trimer, 0.4g of p-chloro-m-dimethylphenol, 0.2g of GPE type polyoxyethylene polyoxypropylene glycerin The ether and 0.2g of anionic polyacrylamide were mixed at the same time, fully stirred with a mixer, and stirred for 30 minutes at a stirring speed of 1000r / min until a latex was formed; in the second step, the latex was stirred for 30 minutes at a stirring speed of 1000r / min, The first vacuuming, the negative pressure value is -0.06MPA; the third step, the latex obtained in the second step is slowly heated up, the reaction temperature is kept at 60 ° C, and the reaction is stirred at a constant temperature for 2 hours, and the stirring speed is 1000r / min , the second vacuuming, the negative pressure value is -0.08MPA, then stop stirring, t...

Embodiment 8

[0045] In Example 8, a filler is added in the second step, and the filler in Example 8 is phenyl o-hydroxybenzoate.

Embodiment 9

[0046] The difference between Example 9 and Example 8 is that the filler of Example 9 is talc.

Abstract

The invention relates to the technical field of automobiles, and particularly discloses a preparation process of durable automobile paint. The preparation method comprises the following steps: 1, mixing the micro-gelling acrylic resin, the HDI tripolymer and the parachlorometaxylenol to form a latex solution; 2, adding the filler into the latex solution; 3, stirring the latex solution prepared in the step 2, then adding water, and cooling to obtain a water-based latex solution; 4, mixing the water-based latex solution prepared in the step 3 with an antioxidant, and performing ball milling in a ball mill to obtain a mixture; and 5, adding water after ball milling, and stirring to obtain the durable automobile paint. The preparation process of the durable automobile paint can be used for preparing the automobile paint, and has the advantage of improving the oxidation resistance and ultraviolet resistance of the automobile paint.

Description

technical field [0001] The present application relates to the field of vehicle technology, and more particularly, to a preparation process of durable automotive paint. Background technique [0002] At present, the huge automobile production and sales market will definitely drive the rapid development of automobile coatings. The huge number of automobiles has provided a broad development space for automobile coatings. The amount of automobile coatings has increased sharply. Good gloss, high gloss, high hardness, good adhesion, the paint film has excellent mechanical properties, excellent gloss retention, weather resistance, abrasion resistance, good acid resistance, alkali resistance, alcohol resistance, gasoline resistance . [0003] Automotive paints include solvent-based coatings as well as water-based coatings. The water-based paint uses water as the solvent, which saves a lot of resources; eliminates the risk of fire during construction; reduces air pollution; only use...
