Water-based heavy-duty single-component primer, as well as preparation method and application thereof

A heavy-duty anti-corrosion, single-component technology, applied in the field of chemical coatings, can solve the problems of long time consumption and high cost that do not belong to the conversion film anti-rust, so as to save the pre-treatment steps of the base material, prolong the anti-rust time, and increase the cost. The effect of closure performance

Example Embodiment

[0049] Example 1

[0050] At room temperature, mix 20 parts by mass of deionized water, 0.2 parts of tert-butanol, 2 parts of propylene glycol methyl ether, 0.2 parts of propylene glycol, 0.2 parts of DF-60, 0.1 parts of bentonite, 8 parts of SZP-391,5 One part of talc powder, 0.3 part of Rhodia DN-642, 7 parts of tannic acid, and 0.5 part of Hemmings FX600 were added to the stainless steel tank under stirring, and the stirring speed was 1200 rpm. Then, it was stirred for half an hour at a speed of 2500 rpm, and the material was ground with a grinder to a fineness of 30 microns or less, and the obtained slurry was filtered to obtain a filtrate for use. Take 40 parts of water-based polyurethane resin, add the above-mentioned filtered slurry, 0.3 part of Hemmings 165F and 0.1 part of Hemmings MA-95 to the water-based polyurethane resin under stirring, where the stirring speed is 800 rpm, and The pH value is adjusted to between 7-9 and the viscosity is adjusted to KU (25°C)≥20GB / T9...

[0053] Example 2

[0054] This example is basically the same as Example 1, except that the content of the added components is different. In this example, 30 parts deionized water, 0.2 parts tert-butanol, 8 parts propylene glycol methyl ether, 0.2 parts propylene glycol, 0.2 parts DF-60, 0.1 parts bentonite, 10 parts SZP-391, 15 parts talc , 1 part of Rhodia DN-642, 1 part of Hemmings FX600, 70 parts of water-based polyurethane resin, 11 parts of tannic acid, 0.6 parts of Hemmings 165F and 0.3 parts of Hemmings MA-95. Table 2 lists the performance data of the primer of this example.

[0057] Example 3

[0058] This example is basically the same as Example 1, except that the content of the added components is different. In this embodiment, 15 parts of deionized water, 0.2 parts of tert-butanol, 4.5 parts of propylene glycol methyl ether, 0.2 parts of propylene glycol, 0.2 parts of DF-60, 0.1 parts of bentonite, 9 parts of SZP-391, and 10 parts of talc are used , 0.5 parts of Rhodia DN-642, 0.75 parts of Hemmings FX600, 55 parts of waterborne polyurethane resin, 8 parts of tannic acid, 0.45 parts of Hemmings 165F, and 0.2 parts of Hemmings MA-95. Table 3 lists the performance data of the primer of this example.

Abstract

The invention relates to a water-based heavy-duty single-component primer, which is prepared from the following components in parts by mass: 18 to 33, preferably 20 to 30, parts of de-ionized water, 1.5 to 10, preferably 2 to 8, parts of a coalescing agent, 6 to 12, preferably 8 to 10, parts of an anti-rust pigment, 3.5 to 17, preferably 5 to 15, parts of filler, 0.3 to 1.2, preferably 0.5 to 1.0, part of a dispersant, 0.08 to 0.4, preferably 0.1 to 0.3, part of a pH regulator, 38 to 75, preferably 40 to 70, parts of a film former, 7 to 11, preferably 8 to 10, parts of a complexing agent and 0.1 to 0.3, preferably 0.2, part of a penetrant. The invention also provides a preparation method and application of the water-based heavy-duty single-component primer.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a water-based heavy-duty anti-corrosion single-component primer. The invention also relates to a preparation method and application of the water-based heavy-duty one-component primer. Background technique [0002] The primers in the prior art do not have the function of rust removal. In the construction process, the rust remover is usually used to remove rust on the metal surface, and then the primer is applied after the rust removal is completed. In this way, the process of painting is cumbersome, time-consuming and costly. In addition, because the working principle of the existing rust remover is to use the adsorption function of the corrosion inhibitor to the newly generated iron atoms on the surface of steel / cast iron, cover the surface of steel / cast iron, and block the contact of iron atoms on the surface of steel / cast iron with air, thereby To achieve the corresponding a...
