Described modification tree ash is obtained by following methods: after first using 10-15% hydrogen peroxide dipping tree ash 2-3h, then with deionized water wash to neutral, dries; Add the nano-sized carbon, the polyisobutene of 1-2%, the tributyl citrate of 2-3%, the ferrocene of 1-2%, the aluminium hydroxide of 3-5% that are equivalent to tree ash weight 2-3%, high speed 4500-4800r/min stirs 20-30min, and ovendry power is broken into ultrafine powder.
The preparation method of the chlorohydrin rubber gasket of nano diatomite modification, comprises the following steps:
(1) by above-mentioned formulation ratio, sent in rubber mixing machine by the raw material prepared and carry out refining glue, glue furnacing temperature controls at 80-90 DEG C, and the refining glue time is 15-20min;
(2) after refining glue completes, taking-up sizing material is paved, after placing cooling 36-48h at normal temperatures, send in vulcanizing press and carry out twice sulfuration, the curing temperature of primary vulcanization controls at 165-175 DEG C, and curing time is 10-15min, and then primary vulcanization is complete carries out second time sulfuration, second time sulfuration is 210-220 DEG C, and curing time is 5-10min, and twice sulfuration pressure is 15-20MPa;
(3) goods completing sulfuration are taken out, through passer, after finishing burr, can finished product be become.
Beneficial effect of the present invention:
The present invention, by carrying out modification to tree ash, can improve flame retardant resistance and the erosion resistance of gasket, and it is low to have cost, the feature of excellent effect.The present invention, by formula adjustment, adds nano diatomite and carries out modification to chlorohydrin rubber, the wear resistance of the gasket that can obviously increase and physical strength.Gasket of the present invention has good resistance to elevated temperatures, sealing property and flame retardant properties; Corrosion resistance is good, and in acid, alkali, can long term operation in wet goods medium, its volume and changes in hardness little, and do not adhere on the metal surface; Frictional coefficient is little, and wear resistance is good; There is the flexibility be combined with trim; Weather-resistant and ozone ageing performance good, the advantage such as durable in use.
