Stearic acid-modified aluminum hydroxide flame retardants

As people s environmental awareness, aluminum hydroxide as having low smoke, non-toxic, good thermal stability, non-corrosive gases, low prices, etc., and flame-retardant effect is good, rich source, in the domestic market with its consumption accounted for more than 80% inorganic flame retardants,  stearic acid

Accounting for over 50% of the total flame retardant, so aluminum hydroxide is a flame retardant broad application prospect. Aluminum hydroxide as an inorganic filler and an organic polymer in the physical form and chemical structure is very different, the affinity difference between the two, if the direct filling will cause dispersion of

Average, and those who will become the size of a large composite stress concentration points, as material weaknesses. These not only limits the added filler in the polymer amount, but also seriously affect the product performance. In order to improve aluminum hydroxide and polymer exclusion knot strength

And interface compatibility, the use of surface modifiers modified aluminium hydroxide is the most effective way. In present the evaluation of the effect of a flame retardant modification mostly to evaluate the final result according to the application, such as measuring the impact strength of the final composite, the tensile strength

, Hardness and other parameters to comprehensive characterization, evaluation reliable and intuitive, but the process route and process complex, long cycle.
