Problems solved by technology

Inorganic flame retardants have the advantages of good adhesion, energy saving and environmental protection, long service life, and oxidation resistance. The disadvantages of low interfacial bonding strength and poor dispersion performance make the flame retardant and mechanical properties of polymer materials decrease, which limits the use of environmentally friendly biomass flame retardants

Abstract

The invention relates to the technical field of processing and modification of polymer materials, and concretely relates to an environmentally-friendly biomass flame retardant and a processing technology thereof. The technology comprises the following steps: sodium alginate and water are mixed, and stand for swelling, the obtained solution is heated and stirred to achieve dissolving, octenyl succinic anhydride is added, the obtained solution is stirred and reacted at a constant temperature, a sodium hydroxide solution is added to adjust the pH value to 8.1-8.2, and the obtained solution is neutralized with hydrochloric acid after the reaction is finished in order to obtain a modified sodium alginate emulsion; modified rice husks, the modified sodium alginate emulsion, plant essential oil,pretreated bone powder, calcium bicarbonate, n-butyl acetate, Escherichia coli, urea ad N,N-dimethylcyclohexylamine are mixed, and the obtained mixture is stirred at a constant temperature, and then is spray-dried to obtain a blank material; and the blank material is treated with trimethylaluminum-containing nitrogen, then is treated with introduced water-containing nitrogen, and is dried to obtain the environmentally-friendly biomass flame retardant. The environmentally-friendly biomass flame retardant provided by the invention has excellent flame retardant properties and excellent mechanicalproperties.

Description

technical field [0001] The invention relates to the technical field of processing and modification of polymer materials, in particular to an environment-friendly biomass flame retardant and its processing technology. Background technique [0002] As the most widely used organic material in today's society, the improvement of its flame retardant performance is an important issue that manufacturers have been studying deeply. The flame retardancy of polymers is a key performance indicator in applications such as fibers, flooring, building and construction materials, pipes, wires, cables, and conveyor belts including mining. [0003] In flame retardant technology, there are three basic principles widely used in the field of polymer flame retardant modification research: (1) gas phase flame retardant mechanism; (2) endothermic flame retardant mechanism; (3) condensed phase flame retardant mechanism. [0004] Among them, the gas-phase flame retardant mechanism is to reduce the h...
