Ultra-fine red phosphorus flame retardant surface coating study
Abstract: The use of inorganic hydroxide and coupling agent on the ultra-fine red phosphorus flame retardant for coating, made of micro-encapsulated red phosphorus in order to improve the stability of red phosphorus. By differential thermal (DTA), infrared spectroscopy (IR), moisture testing and other methods of micro-encapsulated red phosphorus have been characterized, and a variety of factors affect the coating effect of a preliminary study. The experimental results showed: red phosphorus coated with improved stability, moisture absorption rate.
Keywords: hydroxide; coupling; ultra-fine red phosphorus flame retardant; Microencapsulation; stability

Polymer-modified water-soluble silicate coating
Abstract: The aqueous solution of polymer-modified silicate coatings experimental mechanism; to Portland as the main film-forming material, and add other effective polymer composition, used to improve the aqueous solution silicate coating temperature resistance, weather nature, water and so on. use methods are: selected contains R-CH2-OH structure of substances, such as polyvinyl alcohol solution, to increase the viscosity of silicate coatings, while adding heat-shrinkable resin film-forming water emulsion as a supplement objects, so that the organic resin into the Si-O-Si network structure of the gap, the delay in the film in the alternating cold and hot stretching. The results show that the coating has excellent water resistance,
Able to withstand the long-term rainfall, excellent temperature variability, freeze-thaw resistance, aging resistance and so on.
Key words: water-soluble coating; polymer; silicate
