Described modification trees ashes are made by following methods: first use after 10-15% hydrogen peroxide dipping trees ashes 2-3h, more extremely neutral with deionized water wash, 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 the chlorosulfonated polyethylene rubber gasket of nano barite powder modification, comprises the following steps:
(1) by above-mentioned formulation ratio, the raw material preparing is sent in rubber mixing machine and refined glue, glue furnacing temperature is controlled at 80-90 DEG C, and the refining glue time is 15-20min;
(2) after refining glue completes, taking-up sizing material is paved, place at normal temperatures after cooling 36-48h, send in vulcanizing press and carry out twice sulfuration, the curing temperature of primary vulcanization is controlled at 165-175 DEG C, and curing time is 10-15min, and then primary vulcanization is complete vulcanizes for the second time, sulfuration is for the second time 210-220 DEG C, and curing time is 5-10min, and twice sulfuration pressure is 15-20MPa;
(3) goods that complete sulfuration are taken out, through passer, after finishing burr, can become finished product.
Beneficial effect of the present invention:
The present invention, by trees ashes are carried out to modification, can improve flame retardant resistance and the erosion resistance of gasket, and it is low to have cost, the feature that effect is good.The present invention, by formula adjustment, adds nano barite powder and chlorosulfonated polyethylene rubber is carried out to modification, 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, in acid, and alkali, energy long term operation in wet goods medium, its volume and changes in hardness are little, and do not stick on metallic surface; Frictional coefficient is little, and wear resistance is good; There is the flexibility of being combined with trim; The advantages such as Weather-resistant and ozone ageing performance are good, durable in use.
