Step 2: dry superfine glass microballon is added in high-speed mixer, and the solution that adds while stirring step 1 to make, fully take out after stirring 30min;
Step 3: under 80 ℃ of conditions, dry 3 hours, make described modified superfine glass microballoon.
Described coupling agent is Aluminate or titanate esters or stearic acid; Described oiling agent is the wax class.
The making method of the modification HDPE double-wall corrugated pipe that the above formula of a kind of basis is made comprises the following steps:
Step 1: by the mass fraction batching of described modification HDPE double-wall corrugated pipe material therefor;
Step 2: batching is added in high-speed mixer and fully mixes, then enter stirring at low speed, then after transmitting and sieving, material is carried out to preheating, add respectively afterwards the inside and outside layer extruder of double-wall corrugated pipe;
Step 3: plastify and extrude in extruder, and compression molding is double-wall corrugated pipe;
Step 4: after the double-wall corrugated pipe cooling and shaping after compression molding, carry out fixed length cutting.
It is standby that step 2 is delivered to the transition feed bin after mixing of materials, during production and application, within 1 hour, carries out the drying and preheating preheating in advance, and preheating temperature is 90-100 ℃, and carry preheating material with the speed of 600-900kg/ hour.
The operating temperature that the described plasticizing of step 3 is extruded is 190-210 ℃, adopts the method for extruding continuously.
