A kind of magnesium borate crystal whisker-maleic rosin is combined the preparation method of building optical cable sheath material, comprises the following steps:
(1) weigh raw material by weight, first Low Density Polyethylene and methyl phenyl silicone resin are added mixing roll 50-60 DEG C jointly high Speed is blended 10-15min, is subsequently adding maleic rosin and 200-220 DEG C of high speed of Oleum Terebinthinae is blended 10-15min, finally in 165- 185 DEG C of extruding pelletizations, obtain modified poly ethylene base material;
(2) mix all with dehydrated alcohol by weight 1:2-1:3 after VTES and tetraethyl orthosilicate being mixed Even obtaining mixed liquor, the glacial acetic acid being subsequently adding mixed liquor weight 1/10-1/15 stirs, and adds mixed liquor weight 1- 50-60 DEG C of the water of 1.5 times stirring 0.5-1h, is adjusted to neutrality by pH after cooling, add magnesium hydroxide, magnesium borate crystal whisker stirring 2- 4h, filters, is dried, grinds uniformly, obtain modified powder;
(3) first the modified powder in (2), the modified poly ethylene base material in (1) are blended at a high speed 10-15min with triphenyl phosphate, It is subsequently adding remaining raw material and 10-20min is blended at a high speed, carry out extruding pelletization finally by double screw extruder in 200-220 DEG C, Obtain magnesium borate crystal whisker-maleic rosin and be combined building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, maleic rosin and Oleum Terebinthinae to carry out low-density polyethylene body resin Melt blending is modified, thus improves the anti-flammability of matrix resin, pliability and the compatibility with filler;On the one hand to hydroxide Magnesium, magnesium borate crystal whisker powder body carry out vinyl polysiloxane coating modification, can improve toughness and the fire resistance of powder body, again can Improved the binding ability of powder body and matrix resin by graft reaction, promote mechanical performance and the stability of material.More than by The coordination potentiation of material, and with remaining raw material carry out compounding so as to get Cable jacket materials have excellent machinery concurrently Performance and fire resistance, pliability is high, and good weatherability, service life is long, is suitably applied building cable jacket field.
