Abstract

The invention discloses a novel aerogel reinforced nylon thermal insulation composite and a preparation method thereof. According to the invention, the added phosphatide flame retardant scolecite gel can effectively reduce agglomeration and improve compatibility of the gel with nylon through surface organization, so that the stability strength of the composite finished product is enhanced; meanwhile, scolecite, silicon dioxide aerogel and hexabromocyclododecane can achieve a synergistic flame retardant effect, so that carbon layer area of the composite finished product is increased, a gas phase barrier effect is effectively achieved, and the fireproof performance of the composite is enhanced; and benzyl triphenyl phosphonium chloride is adopted for treating esterification sol, so that dehydration, catalysis and carbon formation can be carried out during combustion, and the flame retardant fireproof performance of the finished product is further improved.

Description

technical field [0001] The invention belongs to the field of composite new materials, and in particular relates to a novel airgel reinforced nylon thermal insulation composite material and a preparation method thereof. Background technique [0002] Nylon, as the largest and most important variety of engineering plastics, has strong vitality, mainly because it achieves high performance after modification, and secondly, the automobile, electrical appliance, communication, electronics, machinery and other industries themselves have more and more high-performance requirements for products. The more intense, the rapid development of related industries has promoted the process of high-performance engineering plastics, and the flame-retardant nylon used in electronics, electrical appliances, and electrical appliances is increasing day by day, and the green flame-retardant nylon is getting more and more attention from the market. However, nylon is also There are disadvantages, its c...
