Technical Field
The invention belongs to the technical field of water-based paint for architectural decoration, and particularly relates to water-based paint for indoor wall surfaces.
Background
The water paint is a novel environment-friendly material taking water as a diluent and has ultralow emission. Paint is replaced by water paint, so that the VOC content in the atmosphere can be effectively reduced, and the haze weather is improved. Therefore, the popularization of the water paint is also the mainstream direction of the current coating industry, and is more strongly shown by the people in the industry, and the water paint era in China comes by the policy of '2025 made in China'. Along with the popularization of the internet and indoor fitness equipment, the production and life style of people are more modern, more work and entertainment sports activities can be carried out indoors, shopping is not needed to go on the street every day, and people do not need to frequently go to outdoor activities due to the suitable indoor microclimate, so that most of the activity time of people is spent indoors. According to survey statistics, people spend more than 80% of the time indoors on average every day, and some people even spend more than 93%. Therefore, the relation between the indoor air quality and the human health is more compact, people pay more attention to the indoor air quality, but the existing indoor wall surface water-based paint still has the following defects:
although the concentration of harmful components (including formaldehyde, benzene, ammonia, etc.) in indoor air is often low compared to outdoor air, the cumulative amount of contact is high because people spend indoors for a long time and the time for which the harmful components in air contact the human body is long. Especially for the old, the young, the sick and the disabled, the body resistance is lower, the outdoor activity chance is less, therefore, the health condition of the old, the young, the sick and the disabled is directly influenced by the quality of the indoor air. The existing indoor wall surface water-based emulsion paint has weak adsorption effect on harmful components in indoor air, and some products even release volatile organic compounds such as formaldehyde, benzene, toluene, xylene and the like, thereby seriously harming human health.
In view of this, in order to overcome the above technical problems, the present applicant has designed and developed a novel indoor wall water-based paint, and has adopted a special manufacturing method to solve the above technical problems.
