Abstract

A magnesium-hydroxide-microcapsule flame retardant, comprising magnesium hydroxide as a flame-retardant core, and a surface modification layer, a DOPO layer and a polymeric layer, which sequentially coat the outside of the flame-retardant core. The magnesium-hydroxide-microcapsule flame retardant having a multi-layered structure is constructed in situ by means of a chemical method from magnesium hydroxide and a multi-component flame retardant. Vinylated magnesium hydroxide particles having reactivity are formed under a surface grafting effect of magnesium hydroxide; in addition, intermediate DOPO having a relatively good flame retardant efficiency is selected, and by means of the characteristic of a P-H bond of the intermediate DOPO having extremely high activity to a double bond, the surface of the magnesium hydroxide is coated with a layer of DOPO; and the surface of the magnesium-hydroxide-DOPO capsule is then coated with a thin polymeric layer by means of in situ polymerization. The present invention is used for solving the problems of a magnesium hydroxide flame retardant having a poor flame retardant effect, a high addition amount, and poor compatibility with other materials.

A preparation method for a montmorillonite-magnesium hydroxide composite microencapsulated flame retardant, relating to the technical field of flame retardants. The method comprises the following steps: A. mixing sodium-based montmorillonite with nano-magnesium hydroxide, then adding long chain alkyl quaternary ammonium salt for reacting to prepare inorganic composite modified particles, and reserving same for later use; and B. adding the inorganic composite modified particles prepared in step A to an active monomer solution to prepare a montmorillonite-magnesium hydroxide composite microencapsulated flame retardant. A core material of the obtained composite microencapsulated flame retardant is at least composed of two different substances; magnesium hydroxide and montmorillonite are used as the flame retardant core material; since there is no chemical bond between molecules of magnesium hydroxide and montmorillonite, that is, there is no close interaction, the obtained composite microencapsulated flame retardant is composed of microencapsulated magnesium hydroxide and microencapsulated montmorillonite, and has good dispersibility; moreover, an addition amount of a magnesium hydroxide flame retardant is reduced, so that the inherent mechanical strength and toughness can still be maintained.

Abstract

A neural semantic memory storage method, relating to a technology for few-shot compensation in machine learning. The method comprises: information stored in an external storage memory mechanism is semantic information, i.e., similarity is calculated on the basis of a graph represented by a single-layer neural network; the semantic information is abstracted on the basis of feature representation h and is more expressive; in the whole storage, the size of the semantic information is merely related to categories; that is, the number of the categories is the size of a storage memory, such that requirements for a storage space is reduced, and more convenient and time-saving search is implemented. It is proposed for the first time to use the thought of calculus of variations to generate related semantic distribution, instead of simple semantic information, in an external memory mechanism, and values obtained by performing a sampling technology for multiple times are averaged on the basis of the distribution, so that the generalization ability of semantic information obtained by searching is enhanced to a great extent, and system performance under few-shot learning can be improved to a great extent.
