Abstract

The invention discloses an inorganic flame retardant surface modification method which comprises the following steps: filling an inorganic flame retardant in a surface pretreatment device for heating and preheating, adding a coupling agent into an organic solvent, dissolving the coupling agent in a container, spraying the dissolved coupling agent into a reaction container in the respective container in a high-pressure spraying mode, mounting a stirring rod for fully stirring in the reaction container, and fusing to obtain the surface modified inorganic flame retardant. According to the mode, the aluminum hydroxide and other inorganic flame retardants can be modified through surface treatment and are used for enhancing the adhesion force to polymers and improving the affinity to an interface, so that the dehydration reaction is finished in a certain temperature range.

Description

technical field [0001] The invention relates to a surface modification method, in particular to a surface modification method of an inorganic flame retardant. Background technique [0002] Due to their strong polarity and hydrophilicity, inorganic flame retardants are frequently used in engineering plastic formulations. In applications, the flame retardant effect of inorganic flame retardants increases with the increase in addition, but the filling amount Too much will reduce the strength of the substance, so we add a certain coupling agent to the flame retardant for surface treatment to enhance the flame retardant effect, but the reaction between the flame retardant and the coupling agent is not sufficient to reduce the reaction effect, so a A hybrid approach to improve this situation. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a method for surface modification of inorganic flame retardants, which can...
