The process was the same as in example 3, except that tourmaline was not contained.
Example 6
The process is the same as in example 3, and only 10 parts of tourmaline and 2 parts of monazite are not contained.
The samples of examples 1-3 were coated and tested and the coating properties of the present invention were tested as follows:
the nanometer negative ion powder as the main component of the negative ion slurry is a typical polar crystal, the two ends of the crystal form a positive electrode and a negative electrode, and the positive electrode and the negative electrode at the two ends are not eliminated under the condition of no external electric field, so the nanometer negative ion powder is also called a permanent electrode, negative ions beneficial to the health of human bodies can be generated in a static state, released hydrated hydroxyl ions can continuously decompose organic pollutants such as formaldehyde, benzene, ammonia and the like absorbed and captured on the surface of a coating under illumination, and the nanometer negative ion powder has the comprehensive effects of neutralization, cladding sedimentation, decomposition and the like, can be rapidly and effectively neutralized and clad around free harmful gas particles with positive charges, forms large particle clusters, is rapidly sedimentated and is catalytically degraded, is not floating in the air any more, and is harmless to the health of human bodies. Especially, the hydrated hydroxyl ions can neutralize free radicals and oxidizing gases (putrefactive smell) of oxygen, and the electric field on the surface of the negative ion coating can decompose organic peculiar smell in the electric field, so that the organic peculiar smell can effectively remove and degrade harmful gases and indoor peculiar smell, thereby achieving the purposes of quickly purifying air and having lasting effect.
The experiment detects the negative ion concentration released when the content of the negative ion slurry is different, and the test conclusion is that the negative ion concentration gradually rises along with the increase of the content of the negative ion slurry, but the negative ion concentration is not in a direct proportion relationship, and the increase amplitude is larger when the content of the negative ion slurry is 5.0-15.0% by mass fraction; when the content of the negative ion slurry exceeds 15.0%, the concentration of the negative ions is increased to a certain extent, but the amplitude is not large, so that the formula cost is increased along with the increase of the content of the negative ion slurry, and the content of the negative ion slurry is more ideal about 10% after the comprehensive cost performance.
In order to meet the environment-friendly and environment-friendly ideas, the invention considers the VOC content, the free formaldehyde content, the odor and the like in the product when designing the formula, and also considers the comprehensive performance of the product.
The mildew resistance of building paint products is more and more concerned in the industry, so the selection of mildew inhibitors is particularly important, the mildew inhibitors are selected to have wide application and high-efficiency mildew resistance, meanwhile, the mildew inhibitors have better compatibility to paint products, do not generate chemical reaction with other components, have no influence on the performance of the products, have the characteristics of low volatility, difficult solubility in water and the like, are divided into two major categories of inorganic mildew inhibitors and organic mildew inhibitors, the inorganic mildew inhibitors have great harm to the environment and human bodies, are forbidden to be used in the paint at present, the mildew inhibitors applied to the paint at present are usually organic mildew inhibitors, the types of the organic mildew inhibitors are more, the mildew inhibitors are selected to be the compound products of carbendazim and isothiazoline, have excellent sterilization and bacteriostasis effects on fungi, algae and microzyme, the VOC content is low after being processed by a special process, the other performances of the products are not influenced, and the test results are shown below.
The antibacterial agent is divided into two major classes of inorganic antibacterial agents and organic antibacterial agents, the antibacterial mechanisms are different, the selection of the antibacterial agents is mainly concentrated on the aspects of matching with the paint and green environmental protection, the experiment selects an organic broad-spectrum antibacterial agent which is water-based, has good compatibility with the paint and is stable, the product does not contain free formaldehyde and formaldehyde release bodies, does not contain VOC and AOX, has excellent environmental friendliness, and the antibacterial property test result of the product is shown in the table below.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and those skilled in the art can make modifications to the present embodiment which do not creatively contribute to the present invention as required after reading the present specification, but are protected by patent laws within the scope of claims of the present invention.
