Can.
Originally the preparation method for the asphalt waterproofing material being preferably carried out in mode the performance for having considered each raw material with
And in order to further improve the performance of waterproof material after, further determined that the temperature and time of each mixing, the drip being prepared
The properties of blue or green waterproof material are more excellent.
Originally it is preferably carried out in mode, the mixing temperature of 90# pitches, 10# pitches and softening oil is typical but non-limiting
For 160 DEG C, 161 DEG C, 162 DEG C, 163 DEG C, 164 DEG C, 165 DEG C, 166 DEG C, 167 DEG C, 168 DEG C, 169 DEG C or 170 DEG C；
It is 190 DEG C that the mixing temperature of premix and rubber is typical but non-limiting, 191 DEG C, 192 DEG C, 193 DEG C, 194
DEG C, 195 DEG C, 196 DEG C, 197 DEG C, 198 DEG C, 199 DEG C or 200 DEG C；The incorporation time of premix and rubber is typical but non-limiting
For 2h, 2.1h, 2.2h, 2.3h, 2.4h or 2.5h；
It is 185 DEG C that first modification premix and SBS mixing temperature are typical but non-limiting, 186 DEG C, 187 DEG C, 188
DEG C, 189 DEG C, 190 DEG C, 191 DEG C, 192 DEG C, 193 DEG C, 194 DEG C or 195 DEG C；First is modified premix and SBS incorporation time allusion quotation
Type but it is nonrestrictive be 1h, 1.1h, 1.2h, 1.3h, 1.4h or 1.5h；
It is 175 DEG C that the mixing temperature of second modification premix and talcum is typical but non-limiting, 176 DEG C, 177 DEG C, 178
DEG C, 179 DEG C, 180 DEG C, 181 DEG C, 182 DEG C, 183 DEG C, 184 DEG C or 185 DEG C；Second is modified the incorporation time of premix and talcum
Typical but non-limiting is 0.5h, 0.6h, 0.7h, 0.8h, 0.9h, 1h, 1.1h, 1.2h, 1.3h, 1.4h or 1.5h.
The third aspect, the invention provides a kind of waterproof roll, is mainly prepared by tire base fabric and above-mentioned asphalt waterproofing material
Form.The waterproof roll includes above-mentioned asphalt waterproofing material, therefore with high temperature performance is excellent, water resistance is good and cost is low
The advantages of.
Fourth aspect, the invention provides a kind of preparation method of above-mentioned waterproof roll, comprise the following steps：Use first
Asphalt waterproofing material impregnates to tire base fabric, then successively through overlay film, calendering, cooling, sizing and it is coiled after obtain it is described anti-
Water coiled material.The preparation method technique of above-mentioned waterproof roll is simple, and the waterproof roll being prepared using this method has high/low temperature
Excellent performance, water resistance are good and the advantages of cost is low.
It should be appreciated that above-mentioned dipping, overlay film, calendering, cooling, sizing and the coiled method using in technology are
Can.
It is preferably carried out in one kind in mode, the dipping impregnates for half, and half dipping comprises the following steps：Tire base fabric is passed through
Surface carries the pressure roller of asphalt waterproofing material, and under the pressure of pressure roller, the asphalt waterproofing material of roller surface is immersed in tire base fabric.
The method that the preparation method of this preferably waterproof roll employs half dipping impregnates to tire base fabric, and tire base fabric exists
It is extruded, the air in tire base fabric can be substantially completely discharged while impregnating pitch waterproof material, and existing tire base fabric
Extruded again after being first totally immersed into waterproof material, one due to tire scrim surfaces has the unnecessary waterproof of substantial amounts of waterproof material
Material is not easy to be extruded completely, and apparent mass is poor, and moisture due to the waterproof material for immersing tire base fabric is wrapped up and made by two
Moisture is not easy to discharge, and water resistance is poor；In terms of existing technologies, half infusion process provided by the invention can improve product
Apparent mass, while improve the water resistance of product.
Roller surface is carried it should be noted that pressure roller is the asphalt waterproofing material picked while rotating in oil sump
Asphalt waterproofing material；Or pressure roller is connected with oil circuit, roller surface is set constantly to carry asphalt waterproofing material.The present invention is to this
Implementation is without especially limitation, as long as making roller surface carry asphalt waterproofing material.
It is preferably carried out in one kind in mode, the pressure roller is multiple tracks pressure roller, preferably three pressure rollers.Using multiple tracks pressure roller
Preferably three pressure rollers are impregnated and extruded, and can be sufficiently submerged in asphalt waterproofing material into tire base fabric, make tire base fabric complete
Wrapped up by asphalt waterproofing material, and discharge moisture, improve waterproof effect.
It is preferably carried out in one kind in mode, the pressure of the pressure roller is 4-8MPa, and the rotating speed of pressure roller is 8-14m/min.
Platen pressure is excessive, can too extrude asphalt waterproofing material, and pressure is too small, can cause the moisture in tire base fabric can not be complete
Discharge, therefore, pressure is excessive or the too small waterproof effect that can make waterproof roll is deteriorated, the 4- that this preferred embodiment is formulated
8MPa platen pressure is of moderate size, and is advantageous to improve waterproof effect, while cost-effective.In addition, if the rotating speed mistake of pressure roller
Height can shorten tire base fabric pressing times, cause the moisture in tire base fabric to be fully drained, too low can produce of rotating speed need not
The pressing times for the extension tire base fabric wanted, cause asphalt waterproofing material too to be extruded, therefore, rotating speed is too high or too low to be made
The waterproof effect of waterproof roll is deteriorated, and the pressure roller rotating speed for the 8-14m/min that this preferred embodiment is formulated is of moderate size, favorably
In raising waterproof effect, and the rotating speed and the speed of discharging match, it is possible to increase the globality and continuity of process.
In the preferred embodiment, the pressure of pressure roller it is typical but non-limiting for 4MPa, 4.5MPa, 5MPa,
5.5MPa, 6MPa, 6.5MPa, 7MPa, 7.5MPa or 8MPa；The typical but non-limiting rotating speed of pressure roller is 8m/min, 8.5m/
min、9m/min、9.5m/min、10m/min、10.5m/min、11m/min、11.5m/min、12m/min、12.5m/min、
13m/min, 13.5m/min or 14m/min.
