Preparation method for flame-retardant-type inorganic salt paint

Abstract

The invention belongs to the technical field of chemical paint, and particularly relates to a preparation method for flame-retardant-type inorganic salt paint. The provided flame-retardant-type inorganic salt paint comprises the following component substances in parts by mass: 60-80 parts of a film-forming agent, 10-15 parts of a film-forming enhancer, 18-20 parts of a heat-insulating agent, 4-8 parts of a solvent dispersing agent, 1-2 parts of a thickening agent, and 3-4 parts of a polymerization inhibitor. The flame-retardant-type inorganic salt paint prepared by the preparation method has alower effective density and a lower heat conductivity coefficient because the heat-insulating agent is adopted and added, so the prepared paint has the excellent heat-insulating effect, and has the effect that internal heat cannot be radiated and external heat cannot be transmitted to the interior, thereby the paint can be guaranteed to be applied to more sites. At the same time, because the film-forming agent added to the paint has a lot of lone pair electrons, a stronger hydrogen-bond interaction force can be formed with an attachment, so the paint has very excellent bonding performance, and an adhesive force of the paint can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and in particular relates to a preparation method of flame-retardant inorganic salt coatings. Background technique [0002] With the development of industry, among the VOCs emitted by human production and life, the VOCs emitted by the production and processing of paints rank second, which seriously endangers human health, and the residual liquid organic solvents after its construction are also harmful to human beings. It will cause harm to the environment, and it will also bring harm to the family when it is used at home. The coatings currently on the market are mainly organic coatings, which contain a large amount of organic solvents, which produce a large amount of VOC after use. [0003] Chinese patent CN108219543A discloses a preparation method for an inorganic coating on the surface of woodware, which belongs to the field of inorganic material technology. In the present invention,...

Problems solved by technology

It can form a chemical bond with the valve substrate, so it has good adhesion. At the same time, the coating system is an inorganic system. After nano-composite, the mechanical strength is much greater than the coating prepared by the existing coating, which can effectively prolong the service life of the metal valve. At the same time, the solvent used has certain toxicity and is not a safe and environmentally friendly product. However, the coating has weak bonding ability and its application range is relatively narrow.
