Abstract

The invention discloses high-flame-retardance polyurethane, and belongs to the technical field of polyurethane preparation. The high-flame-retardance polyurethane is prepared from the following raw materials including polyurethane, polycaprolactone diols, alkyd resin, polyester acrylic resin, trimethylolpropane triacrylate, polyacrylic acid, chlorinated rubber, organic silicon resin, azodicarbonamide, diethylenetriamine, benzotriazole, zinc borate, aluminum triphosphate, nitrocotton, sodium molybdate, nanometer aluminum oxide, magnesium hydrate, chlorinated paraffin, mica iron oxide, hydroxypropyl silicone oil, aluminum diethyl phosphonate, sodium metaborate, chlorinated paraffin, emulsified asphalt, dicumyl peroxide, antimonous oxide, nanometer boron nitride, silane coupling agents HK-560and flame-retardance modifying agents through the steps of base material preparation, modifying material preparation, mixing of materials such as base materials and modifying materials and the like.The prepared polyurethane has excellent flame-retardance performance.

Description

technical field [0001] The invention relates to the technical field of polyurethane preparation technology, in particular to a polyurethane with high flame-retardant performance and a preparation method thereof. Background technique [0002] Polyurethane is a polymer containing a carbamate group in the main chain of a macromolecule called polyurethane. Polyurethane is divided into two categories: polyester polyurethane and polyether polyurethane. Polyurethane has many excellent properties, so it has a wide range of uses. [0003] Chinese patent application document "A Polyurethane Material and Its Preparation Method (Application Publication No.: CN106751734A)" discloses a polyurethane material and its preparation method. The polyurethane material is mainly prepared from organosilicon-modified polyurethane prepolymer as a raw material. , low content of free isocyanic acid, green and environmental protection, high mechanical strength, good product stability, no foaming after ...
