Abstract
Description
technical field
[0001] The invention relates to a paint, in particular to a normal-temperature self-drying one-component water-based acrylic anti-corrosion finish paint. Background technique
[0002] There are also some paints for spraying on the surface of objects in the prior art, but the spraying effect is not very satisfactory, and there are shortcomings such as poor appearance quality, easy corrosion, wear, and poor outdoor weather resistance, thereby affecting the appearance quality and image of the object. Moreover, traditional metal coatings are all solvent-based products with high VOC (volatile organic compound) content. During the process of manufacturing, construction, drying, and curing to form a film, the VOC emitted into the air will seriously pollute the environment. With the increasingly stringent environmental protection regulations, the coating industry has gradually developed in the direction of pollution-free, pollution-free, energy-saving, environmentall...
Examples
Embodiment 1
[0040] A kind of preparation method of normal temperature self-drying type one-component waterborne acrylic acid anticorrosion finish paint, it is characterized in that, preparation steps are as follows:
[0041] (1) To prepare a toughening agent, put polyamide and polyurethane into a mixing device in a weight ratio of 3:2 and mix them, and mix them uniformly to obtain a toughening agent;
[0042] (2) Put water-based acrylic resin, dispersant, defoamer, polyethylene glycol dioleate, toughener, lauryl alcohol ester, and deionized water into the paint let-down reactor for reaction and mixing. The mixing time 1H, mixing speed 550r / min; then put mica powder, talc powder, diatomaceous earth, titanium dioxide into the paint let-down reaction kettle and stir and mix, stirring time 1H, stirring speed 750r / min, after stirring evenly, the finished product is obtained.
[0043] The composition includes in parts by weight:
[0044] 30 parts water-based acrylic resin
[0045] Mica powder...
