Water-based polyurethane adhesives can be divided into one-component and two-component according to the form of use. Can be used directly, or without cross-linking agent to get the required performance of water-based polyurethane called one-component water-based polyurethane adhesives. If the required performance cannot be obtained by using alone, cross-linking agent must be added; or generally one-component waterborne polyurethane can improve the bonding performance after adding cross-linking agent, in these cases, the waterborne polyurethane main agent and cross-linking agent both form a two-component system.
Tris (2-chloroethyl) phosphate is an additive flame retardant, containing phosphorus and chlorine at the same time, and the flame retardant effect is remarkable. It is widely used in fireproof coatings, mainly acting as a flame retardant, and can also improve the water resistance, acid resistance, cold resistance and antistatic properties of the coating, especially for transparent fireproof coatings. After the fireproof coating is cured, the coating film is transparent, can maintain the original texture and color of the substrate, and has better fireproof and heat insulation performance.
Tris(2,3-dichloropropyl) phosphate Tris(2,3-dichloropropyl) phosphate, also known as tris(2,3-dichloropropyl) phosphate, molecular formula CgH sO: Cl.P, Relative molecular mass 430.90:
This product is light yellow viscous liquid. Relative density (25℃) 1.5129, auto-ignition temperature 513.9℃, ignition point 282.2℃, flash point 251.7℃, boiling point (0.53kPa) >200℃, freezing point -6℃, initial decomposition temperature 230℃, water solubility (30℃) 0.01% , The solubility of water in it is 0.98%, soluble in chlorinated solvents (such as perchloroethylene), viscosity (23℃) 1850mPa·s, surface tension (25℃) 44×10-N/cm. The phosphorus content is 7.2%, and the chlorine content is 49.1%. This product is not easy to volatilize and hydrolyze, and has good UV stability.
Tris (2.3-dichloropropyl) phosphate is an additive flame retardant and also an additive flame retardant plasticizer. Because it contains both chlorine and phosphorus elements, it has good flame retardancy and a wide range of applications. It can be used for fire retardant coatings prepared from polyvinyl chloride resin, unsaturated polyester resin, epoxy resin, phenolic resin, polyurethane resin, etc. The coating acts as a flame retardant and plasticizer. The fire retardant coating has good fire and heat insulation, mildew resistance, abrasion resistance agent, pollution resistance, water resistance, weather resistance, radiation resistance and electrical properties. Low volatility. It can be used in transparent fireproof coatings to make the film transparent after curing fireproof coatings and maintain the original texture and color of the substrate. It can be used for the surface fire-retardant and flame-retardant treatment of flammable materials such as wood, wood products, paper, cardboard, and fabrics.
(20) Tributyl phosphate Tributyl phosphate, also known as tributyl phosphate, has a molecular formula of Cr2H27OgP and a relative molecular mass of 266.38.
