Description
Technical Field
The invention belongs to the technical field of coatings, relates to a naturally drying coating applied to metal, plastic and glass, and particularly relates to a low-cost water-based quick-drying silvery coating.
Background
At present, common silver coating products for metal decoration and surface protection in the market are air-drying acrylic paint, air-drying polyester ammonia paint, air-drying alkyd paint and the like, which are all oily products, and have the general defects that: all are prepared by using harmful volatile solvents such as toluene, dimethylbenzene, ethyl acetate, butyl acetate and the like. The construction condition requirement is high, the damage to the environment is great, and the probability of respiratory diseases, reproductive system diseases, cancers and other malignant diseases of operators and users is greatly increased.
Along with the development of science and technology, the water paint with safety and environmental protection is more and more popular among people. However, the main raw materials for preparing the water paint, such as water-based resin, water-based aluminum pigment and the like, have the characteristics of high cost, unsatisfactory coating effect, difficult construction, slow drying speed, low glossiness, poor chemical resistance and lower solid content than that of oil resin, so that the produced water paint has higher cost and poor coating effect or cannot meet the process requirements of actual production. The invention aims to solve the problem of high cost of the existing water paint, and simultaneously has the characteristics of quick drying, high glossiness, strong chemical resistance and good coating effect.
Through a search for a patent publication, no patent publication that is the same as the present patent application is found.

a low-cost water-based quick-drying silvery paint is characterized in that: comprises the following components:
moreover, the aqueous thickener comprises the following components:
the preparation method of the aqueous thickener comprises the following steps:
(1) adding deionized water into the reaction kettle;
(2) controlling the rotating speed of a stirring paddle in the reaction kettle, setting the rotating speed to be 500R/min, and adding a water-based dispersant into the reaction kettle;
(3) controlling the rotating speed of a stirring paddle in the reaction kettle, setting the rotating speed to be 1000R/min, and sequentially adding deionized water, polyvinyl alcohol, organic bentonite and fumed silica under the stirring state;
(4) stirring is continued for 1 hour to obtain the aqueous thickener.
Moreover, the pigment ratio of the coating is 0.2-0.4.
Moreover, the pH value of the coating is 6.8-7.5.
The invention has the advantages and beneficial effects that:
1. the water-based quick-drying silver paint with low cost has the advantages that the price of the water-based metal pigment is far higher than that of the oil-based metal pigment, and the price of most of water-based resin is also higher, so that the cost of the water-based silver paint is far higher than that of the oil-based silver paint. The invention is researched and improved on the basis of the oily aluminum pigment, and can prepare the water-based silver powder coating with low cost, good decorative effect, easy construction and high drying speed by matching with the water-dispersible acrylic resin.
2. The low-cost water-based quick-drying silvery coating can ensure that the drying speed, the hardness and the coating effect of the coating are optimal at the moment by controlling the pigment ratio to be 0.2-0.4.
3. The low-cost water-based quick-drying silvery coating can control the pH value of the coating to be about 7 by adding the independently developed water-based thickening agent into the coating, and the pH value is the most popular pH value in the coating industry. The pH value is not suitable for generating mould and is not easy to generate phenomena such as pulverization, foaming and the like.
4. The invention has the advantages of scientific and reasonable design, safety, environmental protection, low cost, easy construction, quick drying, high glossiness, strong chemical resistance and good coating effect, and is a water-based quick-drying silvery coating with higher innovativeness and low cost.
