Description

A kind of CABLE MATERIALS that contains mud

Technical field

The present invention relates to CABLE MATERIALS field, is exactly a kind of CABLE MATERIALS that contains mud.

Background technology

Wire cable insulating and sheath are commonly called as CABLE MATERIALS with plastics, comprising multiple kinds such as rubber, plastics, nylon.The Shi Yi of CABLE MATERIALS manufacturing enterprise cable manufacturing enterprise is user, as long as live wire cable demand just has the market of CABLE MATERIALS.In electric wire product, except the bare wire products such as Aluminium Cable Steel Reinforced, insulated wire, nearly all need insulation layer mouth.China live wire cable manufacturing enterprise is nearly 5000 at present, there are again upgrading urban and rural power grids, development of the West Regions and the great demand of communications facility big area upgrading to electric wire product, thereby from for some time, CABLE MATERIALS has future develop widely in China.

Summary of the invention

The object of the present invention is to provide a kind of CABLE MATERIALS that contains mud.

Above-mentioned purpose realizes by following scheme:

A kind of CABLE MATERIALS that contains mud, it is characterized in that: it is that raw material by following weight parts makes: acrylic elastomer 60-80, succsinic acid mono-glycerides 0.3-0.5, epoxy soybean oil 1-2, PSI 1-2, modified sewage sludge 50-60, straw powder 10-20, barium silicate 1-2, glyceryl monostearate 1-2, zinc oxide 5-12, hydrogenated castor oil 3-5, mineral wool fibre 2-3, mixed gas carbon black 2-4, carborundum powder 12-15, polyethylene HDPE 40-50;

The preparation method of modified sewage sludge is after mud is dried, in the sodium bicarbonate aqueous solution that is 12-18% by concentration, steep while stirring after 1-2 hour, refilter, with deionized water, clean, dry, be equivalent to the polypropylene fibre of mud weight 2-4%, the calcium lignin sulphonate of silane coupling agent KH792,1-2% of 1-2%, after the red phosphorus of 1-2% mixes, adding 10-15% hydrochloric acid soln tune PH is 4-5, at 50-60 ℃, stir after 10-20 minute, repeated hydrogenation sodium oxide is adjusted to neutrality, and ovendry power is broken into powder and get final product.

Described a kind of CABLE MATERIALS that contains mud, is characterized in that:

Preparation method is:

(1) get acrylic elastomer, PSI, succsinic acid mono-glycerides, epoxy soybean oil and mix by weight, in kneader, at 120-128 ℃, mediate after 7-9 minute, take out cooling;

(2), by the cooled material of step (1) gained and each raw material blending of residue, mixing in twin screw extruder, granulation, control temperature at 138-160 ℃, obtains finished product.

Beneficial effect of the present invention is: the present invention contains modified sewage sludge, and mud is through sodium bicarbonate sterilization and disinfection, and follow-up modified-reaction, and gained sludge quality is stable, and harmless, when turning waste into wealth, physical properties is strong.

Embodiment

A kind of CABLE MATERIALS that contains mud, it is that raw material by following weight kg makes: acrylic elastomer 80, succsinic acid mono-glycerides 0.5, epoxy soybean oil 2, PSI 1, modified sewage sludge 60, straw powder 20, barium silicate 2, glyceryl monostearate 2, zinc oxide 8, hydrogenated castor oil 5, mineral wool fibre 3, mixed gas carbon black 4, carborundum powder 15, polyethylene HDPE 50;

The preparation method of modified sewage sludge is after mud is dried, in the sodium bicarbonate aqueous solution that is 18% by concentration, steep while stirring after 2 hours, refilter, with deionized water, clean, dry, after polypropylene fibre, 2% silane coupling agent KH792,2% calcium lignin sulphonate, 1% the red phosphorus that is equivalent to mud weight 3% mixes, adding 15% hydrochloric acid soln tune PH is 5, at 58 ℃, stir after 20 minutes, repeated hydrogenation sodium oxide is adjusted to neutrality, and ovendry power is broken into powder and get final product.

Described a kind of CABLE MATERIALS that contains mud,

Preparation method is:

(1) get acrylic elastomer, PSI, succsinic acid mono-glycerides, epoxy soybean oil and mix by weight, in kneader, at 128 ℃, mediate after 9 minutes, take out cooling;

(2), by the cooled material of step (1) gained and each raw material blending of residue, mixing in twin screw extruder, granulation, control temperature at 140 ℃, obtains finished product.

The present embodiment is carried out to performance test, tensile strength 18.9MPa, elongation at break 420%, fire-retardant rank V0.
