S1: by polyolefinic raw materials by driving screw rod to the intracorporal polyolefin in storehouse original by driving part in feed inlet investment warehouse
Material is conveyed;
S2: pure water is conveyed in warehouse by constant flow high pressure water pump, water injection rate is the 11% of low smell polyolefine material yield
To 15%, the pressure of constant flow high pressure water pump is greater than 0.8MPa;
S3: microwave is provided into warehouse by ultrasonic generator, microwave, which does medium by pure water, makes the volatilization of polyolefinic raw materials
Substance forms hydrone microvesicle;Ultrasonic frequency is set as 15KHz-200KHz;
S4: warehouse out is extracted hydrone microvesicle by vacuum pump, the intracorporal vacuum area vacuum degree in storehouse is greater than 0.8;
S5: smell polyolefine material is squeezed out from discharge port by screw rod.
9. the method according to claim 8 for preparing low smell polyolefine material, which is characterized in that in the S2 step:
The pressure of constant flow high pressure water pump is greater than 1.3MPa;In the S3 step: ultrasonic frequency is set as 15KHz-100KHz;The S4
In step: the intracorporal vacuum area vacuum degree in storehouse is greater than 1.0.
10. the method according to claim 8 for preparing low smell polyolefine material, which is characterized in that in the S2 step:
The conveying capacity of pure water and resin extruded output quantity are controlled 5% to 30%.
