Described modification trees ashes are made by following methods: extremely neutral with deionized water wash again after using first 10-15% hydrogen peroxide dipping trees ashes 2-3h, and oven dry; Add and be equivalent to the nano-sized carbon of trees ashes weight 2-3%, the polyisobutene of 1-2%, the tributyl citrate of 2-3%, the ferrocene of 1-2%, the aluminium hydroxide of 3-5%, high speed 4500-4800r/min stirs 20-30min, and ovendry power is broken into ultrafine powder.
The preparation method of chlorosulfonated polyethylene rubber/neoprene packing pad may further comprise the steps:
(1) press above-mentioned formulation ratio, the raw material for preparing is sent into refined glue in the rubber mixing machine, glue furnacing temperature is controlled at 80-90 ℃, and the refining glue time is 15-20min;
(2) after refining glue is finished, the taking-up sizing material is paved, after placing at normal temperatures cooling 36-48h, send into and carry out twice sulfuration in the vulcanizing press, the curing temperature of primary vulcanization is controlled at 165-175 ℃, and curing time is 10-15min, primary vulcanization vulcanizes the second time by complete and then carrying out, for the second time sulfuration is 210-220 ℃, and curing time is 5-10min, and twice sulfuration pressure is 15-20MPa;
(3) goods that will finish sulfuration take out, and through the passer, can become finished product behind the finishing burr.
Beneficial effect of the present invention:
The present invention can improve flame retardant resistance and the erosion resistance of gasket by the trees ashes are carried out modification, and it is low to have a cost, the characteristics that effect is good.The inorganic nano powder such as nanometer celestite powder, nano silicon have been added, the wear resistance of the gasket that can obviously increase and physical strength in the present invention's prescription.Gasket of the present invention has good resistance to elevated temperatures, sealing property and flame retardant properties; Corrosion resistance is good, in acid, and alkali, energy long term operation in the wet goods medium, its volume and changes in hardness are little, and do not stick on the metallic surface; Frictional coefficient is little, and wear resistance is good; Has the flexibility of being combined with trim; The advantages such as Weather-resistant and ozone ageing performance are good, and be durable in use.
