If you want to build an environment-friendly and healthy home, what is green paint? Is it a concept with the environmental protection coating that we often hear? It is necessary to make it clear that there are two kinds of green coatings &mdash& mdash; Health coatings and energy-saving coatings. Paint is indispensable for home walls. If you want to build an environment-friendly and healthy home, you have to understand the five essential properties of green paint

first, non-toxic, odorless, non combustible &mdash& mdash; Water based coating

environmental protection features: water is different from most organic solvents in that it is non-toxic, odorless and non combustible. Introducing water into the coating can reduce the cost of the coating and the fire caused by the existence of organic solvents in the construction. Therefore, water-based coating not only has the advantages of non-toxic, odorless and non combustible, but also has a very limited VOC content, which makes water-based coating a very practical green coating

health performance: as an ideal green paint, it has the advantages of fast drying speed, strong adhesion, high toughness, good adhesion, rust prevention and so on

applicable space: widely applicable to all spaces of family decoration

II. Absolute zero organic volatile substances &mdash& mdash; Dust coating

environmental protection features: powder coating is made of special resin, pigments and fillers, additives or curing agents mixed in a certain proportion, and then prepared through hot extrusion, crushing and screening processes. After heating, baking, melting and curing, it forms a flat and bright permanent coating film to achieve the purpose of decorating and protecting the wall

health performance: powder coating is a new type of 100% solid powder coating without solvent. Theoretically, it is absolutely zero organic volatile matter coating. Its product recovery rate is more than 95%. The ultra-fine waste powder with a content of less than 5% produced in the production process can be reused in production after being recycled through the recovery system, basically achieving zero emission

applicable space: it can be painted on the surface of special materials, such as metal, plastic, etc

III. solvent based coating upgrading &mdash& mdash; High solid content solvent based coatings

environmental protection features: high solid content solvent based coatings are developed from ordinary solvent based coatings in order to adapt to increasingly stringent environmental protection. Its main feature is to reduce the amount of organic solvents and improve the composition of solid tissues to meet the requirements of environmental protection and health on the premise that the original production methods and coating processes can be used

health performance: generally, the solid content of low solid content solvent based coatings is 30%-50%, while high solid content solvent based coatings are required to reach 65%-85%, or even higher. In the formulation process, high solid content solvent based coatings use some solvents that are not listed in the list of organic volatile substances as diluents to reduce the content of organic volatile substances

applicable space: it can be used in spaces or parts with special needs for small-area painting, such as local spaces that need fire prevention and corrosion prevention

fourth, let the home be like spring all the year round &mdash& mdash; Thermal insulation coating

environmental protection features: thermal insulation coating integrates the dual characteristics of coating and thermal insulation materials, and forms a thermal insulation layer with certain strength and elasticity after drying

health performance: the thermal insulation coating can be fully bonded with the base, with strong integrity, especially suitable for the insulation of special-shaped equipment that is difficult to be solved by other thermal insulation materials; The construction is relatively simple and can be carried out manually; The material production process is simple and energy consumption is low

applicable space: indoor and outdoor walls that need to maintain room temperature can be used, such as the elderly room, children's room, etc

v. quiet small world &mdash& mdash; Sound insulation and noise proof coating

environmental protection features: the coating with sound insulation function is composed of resin lotion and polycrystalline ceramic slag powder &mdash& mdash; The slag discharged from refining copper is the main component, which is made with other additives. In the coating, slag and resin have good mixing property, and the sound insulation filler can be infiltrated into it, so that the prepared coating can obtain good sound insulation property

health performance: because this coating is prepared with slag, the cost is low, and in addition to the existence of copper slag, it can also play the role of rust prevention, oxidation prevention and flame retardant. The test shows that the sound insulation performance index of gypsum board coated with sound insulation paint on the surface of gypsum board with a thickness of 9 mm is higher than that of gypsum composite board composed of two boards with a thickness of 9 mm

applicable space: for walls with poor sound insulation effect or rooms near the road, sound insulation paint can be used, and some spaces with special needs are also applicable, such as audio-visual room
