Problems solved by technology

[0010] It can be seen that the control of the content of carbon dioxide in the indoor air plays a vital role in the health of the human body. However, in large places that are not conducive to ventilation and poor ventilation and in the family room, the absorption of carbon dioxide by the interior wall coating can be used to reduce the carbon dioxide in the air. There are still relatively few studies on the content of calcium powder, among which the title "Absorbing CO 2 In the paper of "Performance Research on Performance" (Authors: Xu Feng, Zhu Xiaobo), it is proposed to add ash calcium powder to interior wall latex paint to reduce indoor CO2. 2 content, but in this article it is only discussed that adding ash calcium powder to latex paint can reduce indoor CO 2 content and its test method, but did not propose how to prepare latex paint capable of absorbing carbon dioxide, and did not further point out whether adding lime calcium powder to ordinary latex paint would affect other performance indicators of latex paint, such as the applicant in the study It was found that the addition of ash calcium powder to ordinary latex paint would cause the latex paint particles to become coarser, affect the leveling performance of the latex paint, produce a large number of bubbles, poor dispersion performance, and gel state of the thickener.

Description

Technical field [0001] The invention relates to an architectural paint, in particular to an interior wall latex paint. Background technique [0002] If the indoor air flow is poor and the ventilation cannot be performed well, the content of carbon dioxide in the air will inevitably increase. As the content of carbon dioxide increases, the harm of carbon dioxide to the human body will gradually increase, such as: [0003] When the content of carbon dioxide in the air is about 0.03%, carbon dioxide is non-toxic, and people will not be harmed in such an environment; [0004] When the content of carbon dioxide in the air is 0.1 to 0.25%, the human body will feel discomfort; [0005] When the content of carbon dioxide in the air reaches 2.5%, you may experience headaches and dizziness; [0006] When the content of carbon dioxide in the air reaches 3.0%, the number of breaths increases, and the weak may feel headache and dizziness; [0007] When the content of carbon dioxide in the air reache...
