Abstract

The invention discloses a surface flame retardant coating of rubber as well as a preparation method of the coating. The surface flame retardant coating comprises components A and B. The preparation method comprises the following steps: mixing and stirring a diluent, a dispersant, an adhesive force accelerant, a chain extender, halogen-free flame retardant polyether, a liquid flame retardant and flame retardant filler to obtain coarse mill base; grinding the coarse mill base to fine mill base; adding a free radical polymerization inhibitor, an ultraviolet light absorber, a catalyst and a defoamer into the fine mill base to stir to obtain the component A; adding an isocyanate curing agent and other assistants into the diluent to stir to obtain the component B; and mixing and stirring the components A and B to obtain the surface flame retardant coating of rubber. The flame retardant coating disclosed by the invention has the advantages of efficient flame retardance, low smoke and low toxicity, good weather ability and long service life, and the preparation method is simple in process, easy for production on a large scale and lower in production cost.

Description

technical field [0001] The invention belongs to the technical field of polymer material preparation, and in particular relates to a low-smoke and low-toxicity rubber surface flame-retardant coating and a preparation method thereof. Background technique [0002] With the popularization of high-speed transportation and logistics, high-speed transportation has been vigorously developed, and the application of rubber vibration isolation devices is indispensable. The damping hysteresis and the limitation of the damping force of the traditional metal spring vibration-isolating parts are difficult to adapt to the driving stability of the high-speed train and the comfort of the passengers. The application of metal rubber vibration-isolating parts to vehicles can well solve the above-mentioned defects of damping performance, but due to the limitation of the performance of rubber itself, its flame-retardant performance is poor, and it can burn at medium and high temperatures, and the ...
