Wash-resistant waterborne negative ion diatom ooze formula and preparation method thereof

Abstract

The invention discloses a wash-resistant waterborne negative ion diatom ooze formula and a preparation method thereof. Diatomite, nano titanium dioxide, silicon acrylic emulsion, a dispersing agent, aphotoinitiator, aluminum triphosphate and deionized water are mixed according to a proportion; then extender pigment, sodium silicate, polyimide, fumed silica, ammonium polyphosphate temperature resistant additive, p-nitrobenzoic acid, an aliphatic series curing agent and asbestos powder are added to modify the materials; finally, negative ion powder, cellulose and bamboo carbon fiber are added to improve viscosity, so that produced diatom ooze has no toxic gas generation, environmental friendliness are achieved, and harm to the human body is reduced; the negative ion powder and rare earth compound can release a lot of negative ions, so that the density of the negative ions in space can be kept as 1,400 to 1,600 ion / CM<3>, and health of the human body is promoted; the diatom ooze has strong adsorption capacity and good breathability and can decompose toxic gas of formaldehyde and the like; the air humidity can be controlled between 50% to 60% which is the most comfortable range for the human body and is favorable for people to enter deep sleep.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a scrub-resistant water-based anion diatom mud formula and a preparation method thereof. Background technique [0002] Diatoms are a major group of eukaryotic algae. One of the main features of diatoms is that the diatom cells are covered with siliceous (mainly silicon dioxide) cell walls. The texture and shape of siliceous cell walls are different, but most of them are arranged symmetrically. This arrangement can be used as the basis for classification naming. But this symmetry is not perfect, because one side of the diatom cell wall is slightly larger than the other, so that it can fit together. Fossil remains show that diatoms originated in the Early Jurassic period at the latest. Only the male gametes of central diatoms have flagella and can swim. Diatoms have always been an important indicator species for environmental monitoring and are often used in water qual...

AI Technical Summary

Problems solved by technology

[0007] (1) The current diatom mud has a single composition and has no antibacterial effect. After a long time of storage, it will produce a large odor inside, which will affect people's use; (2) Most of the existing diatom mud on the market is dry powder When using it, it needs to be mixed and stirred with water first. Because diatom ooze has high requirements on technology, it is difficult for on-site staff to deploy diatom ooze with superior performance, and the construction cost is higher; (3) the existing diatom ooze It is difficult to control the amount of water to be added. If too much water is added, powder will fall off. The existing diatom mud on the market has poor strength and is not resistant to scrubbing. It is easy to fall off when it is pulled by hand or pressed by foreign objects (4) Ordinary diatom mud is often added with binders such as lime cement and latex powder in order to be bonded to the wall. These materials often react with porous materials such as diatomaceous earth. Many breathing holes make the air permeability of diatom ooze poor, destroy the breathability of diatom ooze, and cannot release the function of negative oxygen ions; (5) The existing diatom ooze has low adsorption efficiency and limited adsorption capacity. The technical method combined with photocatalyst has problems such as poor light intensity, light energy utilization rate of catalyst, and poor catalytic degradation efficiency and effect on formaldehyde.
