改性纯丙乳液膨胀型防火涂料的制备

Preparation of Modified Acrylic Latex Intumescent Fire-retardant Coatings

通过向纯丙乳液中加入脲醛树脂,提高了涂膜熔融时的黏度,改善了纯丙乳液防火涂料的发泡结构,使纯丙防火涂料的防火性能大大提高,同时研究了脲醛树脂的加入量以及对涂层的影响。

Adding urea-formaldehyde resin to pure acrylic latexcan increase the viscosity of film melting, modify the foamingstructure of acrylic latex fire-retardant coatings and greatlyimprove the fire-retardant performance. Urea-formaldehyderesin quantity and the influence on coatings are discussed.
