specific Embodiment approach 1

[0018] Specific implementation mode one: the preparation method of the environmental protection liquid coating type negative ion diatom mud coating of this embodiment is carried out according to the following steps:

[0019] 1. Preparation of negative ion diatom mud powder:

[0020] Weigh 30-50 parts of nano tourmaline, 10-20 parts of nano-rare earth material, 50-100 parts of nano-titanium dioxide, 40-100 parts of superfine calcium hardate, 50-110 parts of ultra-fine talcum powder, and 100-300 parts of fine diatomaceous earth is used as raw material, the raw materials are mixed evenly, dried at a temperature of 50-60°C for 6-12 hours, and then sieved to obtain negative ion diatom mud powder;

[0021] 2. Put 0.5-1.5 parts of defoamer, 2.5-3.5 parts of thickener, 4.5-5.5 parts of dispersant and 110-130 parts of water into the mixer, stir and disperse at a stirring speed of 800-1200r / min for 2-5 minutes , to get the primary mixture;

[0022] 3. Add 115-125 parts of negative ion...

specific Embodiment approach 2

[0027] Embodiment 2: This embodiment differs from Embodiment 1 in that: the aperture of the sieve used for sieving in step 1 is 80-100 mesh.

specific Embodiment approach 3

Abstract

The invention discloses a preparation method of an environment-friendly liquid brushing type negative ion diatom ooze coating, and relates to a preparation method of a diatom ooze coating. The invention aims to solve the problems that existing diatom ooze coatings easily cause an indoor secondary pollution source and pores of diatomite are easily blocked. The method comprises the following steps: preparing a negative ion diatom ooze powder by taking nano tourmaline, a nano rare earth material, nano titanium dioxide, superfine calcium stearate, superfine talcum powder and superfine diatomite as raw materials, stirring and dispersing a defoaming agent, a thickening agent, a dispersing agent and water, adding the negative ion diatom ooze powder with stirring, and then adding acrylic resin dispersion, a coalescing agent, the defoaming agent and single-layer graphene. The coating disclosed by the invention is high in negative ion release concentration, and can achieve the effects of removing harmful gases such as formaldehyde and benzene for a long time, purifying indoor air, resisting bacteria, preventing mildew and resisting aging. The method is suitable for preparing the diatom ooze coating.

Description

technical field [0001] The invention relates to a preparation method of diatom mud coating. Background technique [0002] With the improvement of people's living standards and the enhancement of ecological environmental protection and health awareness, higher requirements are put forward for the selection and use of home decoration materials. [0003] How to meet people's use requirements in the increasingly competitive interior decoration materials has become a priority for major manufacturers. Diatomite is essentially a biogenic siliceous sedimentary rock with a melting point of 1400°C and a molecular weight of 60. It is mainly distributed in China, the United States, Japan, Denmark, France, Romania and other countries. my country's diatomite reserves are 320 million tons, and the prospective reserves are more than 2 billion tons, mainly concentrated in East China and Northeast China. Among them, Jilin, Zhejiang, Yunnan, Shandong, Sichuan and other provinces are large in ...
