Coating formulation: Configuration Technology of reflective heat insulation coating

Core tips: 1 In general, the use of different emulsion will affect the physical and mechanical properties of the coating without affecting the reflective properties of the coating For example, organosilicon acrylic acid composite emulsion can effectively resist ultraviolet oxidation of the film, and enhance the stain resistance of the coating due to the high hardness and low surface energy of the coating, especially for the preparation of reflective insulation coatings The selection of pigments and coatings mainly focuses on the reflection performance In recent years, the solar reflective thermal insulation coating prepared by using hollow microspheres as functional filler has good reflective performance, which makes Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: 1, raw materials selection, in general, the use of different emulsion will affect the physical and mechanical properties of the coating, but will not have a significant impact on the reflective properties of the coating For example, organosilicon acrylic acid composite emulsion can effectively resist ultraviolet oxidation of the film, and enhance the stain resistance of the coating due to the high hardness and low surface energy of the coating, especially for the preparation of reflective insulation coatings The selection of pigments and coatings mainly focuses on the reflection performance In recent years, the solar reflective thermal insulation coating prepared by using hollow microspheres as functional filler has good reflection performance, which makes this kind of coating become a new type of coating, improves the application performance and expands the application field 2 The design of coating formulation solar thermal reflection heat insulation coating is a kind of high-performance functional coating used outdoors, which also has high requirements for other physical properties of the coating, such as weather resistance, atmospheric corrosion resistance, acid rain resistance, etc Therefore, the characteristics of the formulation are as follows: first, the PVC concentration of the coating should not be too high under the requirements of the reflective property of the coating film, otherwise the performance of the coating would be adverse; second, the formulation of hollow glass The content of the bead should not be too low, which can form a continuous reflecting surface, and its amount should be higher than 20% by mass; thirdly, if the base material is thermosetting resin, it should be noted that the glass transition temperature of the resin should not be too low, generally higher than 25 ℃; fourthly, it is not allowed to select materials that can significantly absorb light and heat, especially the selection of fillers and pigments The basic formula for the production of solar thermal reflective thermal insulation coating raw material dosage (mass fraction) /% raw material dosage (mass fraction) /% Formula 1 Formula 2 Formula 1 Formula 2 water 12.090.0 titanium dioxide (rutile type) 20.0 -- mould inhibitor 0.12.0 functional filler -- 150.0 glycol (or propylene glycol) - 10.0 hollow glass bead 25.0200.0 anion dispersant 0.6 ～ 0.8 2 coloring pigment or colouring agent -- proper amount of ester alcohol -12 (or propylene glycol butyl ether) 2 ~ 2.5 -- elastic polyacrylate emulsion 40 500 wetting agent 1 defoamer 0.4 proper amount of ammonia (pH buffering agent) 0.4 The preparation of solar reflection thermal insulation coating is similar to that of common coating, which is a physical mixing process However, in the design of production process, it should be noted that the vacuum glass beads cannot be grinded (the formula of this article is for reference only) coatings home is focused on the news and information of coatings, diatom mud, paint coatings, coating technology, fire retardant coatings, coatings, diatom mud, paint coatings, coating technology, decoration knowledge and decoration effect map of fire retardant coatings,
