Embodiment 1

[0064] In this embodiment, a kind of corrugated pipe filling masterbatch is prepared, and the specific process is as follows:

[0065] S1. Finely grind the defective glass products recovered from the glass fiber manufacturing enterprises to obtain glass powder with a particle size of about 10 μm;

[0066] S2. Put the glass powder obtained in step S1 in a high mixer, and stir at 100° C. for 1 hour to remove water;

[0067] S3. In the glass powder obtained in step S2, add KH550 accounting for 1% of the glass powder mass, continue to stir for 1 hour, stop stirring and cool to normal temperature to obtain modified glass powder;

[0068] S4. According to the ratio shown in Table 1, after mixing modified glass powder, high-density polyethylene A, maleic anhydride grafted polyethylene, PE wax, antioxidant and lubricating stabilizer for 10 minutes, add talcum powder, and then continue to stir 10min;

[0069] S5. Extrude the mixed system obtained in step S4 at 140°C with a parallel c...

Embodiment 2

[0072] This example prepares a kind of corrugated pipe filling masterbatch, the specific difference with example 1 is:

[0073] The components are different, and the detailed ratio is shown in Table 1.

Abstract

The invention discloses a corrugated pipe filling master batch as well as a preparation method and application thereof, and belongs to the technical field of corrugated pipe preparation. The corrugated pipe filling master batch comprises the following components: high-density polyethylene, modified glass powder, talcum powder, maleic anhydride grafted polyolefin and PE wax. The main filler adopted by the invention is modified glass powder, and the price of the filler is equivalent to that of calcium carbonate powder and is lower than that of talcum powder, so that the corrugated pipe filling master batch provided by the invention is relatively low in raw material price; and compared with calcium carbonate powder or talcum powder, the filler can be mined without destroying the environment, waste glass can be recycled, and the green production concept is met.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipe preparation, and in particular relates to a corrugated pipe filling masterbatch, a preparation method and an application. Background technique [0002] A bellows is a cylindrical thin-walled corrugated shell with multiple transverse corrugations. The bellows are elastic and can generate displacement under the action of pressure, axial force, lateral force or bending moment. [0003] Bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm diaphragm boxes and metal hoses. Among them, bellows made of plastic and other materials play an irreplaceable role in the fields of medium transportation, power threading, machine tools, and home appliances. According to the number of pipe wall layers, bellows can be divided into single-wall bellows and double-wall bellows. The double-wall corrugated pipe made of high-density polyethylene (HDPE) has ...
