Description
Technical Field
The invention belongs to the field of building decoration materials, and particularly relates to anion-containing waterproof heat-insulation interior wall putty powder.
Background
The putty powder is a commonly used building decoration material, is used for leveling the surface of a wall body, is thick paste-shaped paint, is an essential product before painting, is coated on primer or directly coated on an object, is used for eliminating the defects of high and low unevenness on the surface of the painted object, and lays a foundation for obtaining a uniform and smooth painted surface. The filler is mainly heavy calcium carbonate, talcum powder and the like, can fill a working surface with a local recess, can also be scraped off on the whole surface, and is usually applied to the surface of a primer layer after the primer layer is dried completely. It is required to have good adhesion and not to generate cracks during baking.
In recent years, with the increasing requirements of people on building quality, the development of putty powder is also continuously improved, and in the coming years, the waterproof putty occupies more markets. The putty is divided into an inner wall and an outer wall, and the putty for the outer wall has large adhesiveness, high strength and slightly low environmental protection index because the putty for the outer wall resists wind, wind and sun. The interior wall putty has better comprehensive index, is healthy and environment-friendly, so the interior wall is not externally used, and the exterior wall is not internally used. The interior wall putty powder contains volatile organic solvent components, and mainly generates volatile organic compounds, free formaldehyde, soluble heavy metals such as lead, cadmium, chromium and mercury and the like, and harmful substances such as benzene, toluene, xylene and the like in the construction and use processes. Lead, cadmium, chromium and mercury are common toxic pollutants, and soluble substances of the lead, the cadmium, the chromium and the mercury are obviously harmful to human bodies. Harmful substances such as benzene, toluene, xylene and the like can cause symptoms such as dizziness, headache, nausea and the like to the people through respiratory tract inhalation, have certain stimulation effect on eyes and nose, and can cause asthma, obnubilation, vomiting, bronchitis and the like in severe cases. The formaldehyde has strong irritation to skin, eyes and respiratory tract, so that the human body has sensitization reaction and the health of the human body is influenced.
The negative ions are gas ions with negative charges in the air, and the negative ions not only can promote the synthesis and storage of vitamins in the human body and strengthen and activate the physiological activities of the human body, but also have very important influence on the life activities of the human body and other organisms, so the negative ions are also called as 'air vitamins'. It is considered that it has very important influence on the life activities of human body and other living things like vitamins of food, and some even thought that air negative ions are related to longevity, so it is called "longevity element". For each positive and negative ion, its lifetime is short, typically only a few tens of minutes. The air is good after thunderstorm, which is a feeling that everyone has experienced because, every time after thunderstorm, the gas molecules in the air dissociate from negatively charged negative ions under the action of lightning. Generally, people require about 130 million negative ions per day, and our environment such as bedrooms, offices, entertainment venues, etc. is seriously insufficient. The technical problem to be solved is to add negative ions into putty powder to improve the building quality.
