氢氧化铝-氢氧化镁合剂
1.Three kind of various polyamine benzoxazine ,MDA60-BOZ, PM-BOZ and PN-BOZ are prepared from formaldehyde, phenol, aniline and melamine while PM is synthesized through the reaction between melamine, formaldehyde and phenol, and PN is synthesized by rearrangement reaction of condensation between formaldehyde and aniline at 90-95℃.
2.The environment resistance of color chlorosulfonated polyethylene(CSM)compound was studied with dicumyl peroxide as vulcanizator ,N ,N′-metaphenylene as co-vulcanizator, ester(WB 350)(10～15 phr)/trioctyltrimelliteta (TOTM)(8～10 phr)/ethylene-vinyl acetate copolymer(15～20 phr) as complex plasticizers,LEE powder(30～40 phr)/calcined clay (45～55 phr)/precipitated barium sulfate(40～50 phr)as fillers,aluminium hydrate(35～40 phr)/magnesium hydrate(20～30 phr)/antimony trioxide(10～15 phr) as flame retardants,and zinc stearate(1.0～1.5 phr) as surface treating agent in CSM(85～90 phr)/EPDM(15～10 phr) blended system.
5.This paper introduces the working nechanism and the development prospect of Mg(OH)2 as flame retardant.
6.The surface of magnesium hydroxide is modified with stearic acide, and this paper elaborates the influence of factors such as quantities of stearic acide, time, temperature.
7.The series, development trend of fire retardant and the advantage of magnesium hydroxide as fire retardant are introduced simply.
8.Magnesium-hydroxide powder features high purity, well distributed particle size, extremely low in impurity.
9.a milky white liquid suspension of magnesium hydroxide; used as a laxative and antacid.
10.The mechanism of the decolorization is due to the adsorption of magnesium hydroxide formed and the data are confirmed with the Langmuir isotherm equation.
