Problems solved by technology

Once the rigidity of PVC-U drainage pipes decreases, the tensile strength cannot meet the test requirements
On the other hand, since the price of rubber elastomers such as CPE, MBS, and ACR is higher than that of PVC, using them to modify PVC-U drainage pipes always increases the cost.

Embodiment Construction

[0012] The invention discloses a method for processing nanometer drainage pipes. The processing steps are divided into:

[0013] ①The first step is to mix firstly: add each combination of raw materials into the hot mixer according to the proportion and mix them, the materials will heat up by stirring and friction, and then the materials will be cold mixed and discharged;

[0014] ②The second step is extrusion: the stirred mixture is put into the hopper of the extruder, metered into the conical twin-screw extruder, the temperature, material pressure and extrusion speed are controlled, and the pipe is extruded from the extrusion die;

[0015] ③ The third step is shaping: after the extruded pipe is cooled and shaped by a sizing sleeve in a vacuum cooling box, continue to cool in a water cooling box to 40°C or lower, such as 30°C to 50°C;

[0016] ④ The fourth step is cutting and testing: the cooled pipe is printed and cut according to the required length, and then tested and qual...

Abstract

A draining pipe is made up of calcium carbonate nanoparticles, PVC resin, stabilizer, lubricant and filler through proportional mixing, heating while stirring, cold stirring, extrusion forming by dual-screw conic extruder and extruding die to obtain pipe, vacuum cooling in sizing sleeve, water cooling, cutting short and testing.

Description

technical field [0001] The invention relates to a processing method of nano drainage pipes, in particular to a processing method of PVC-U nano drainage pipes, belongs to the field of plastic building materials, and is mainly used for drainage in buildings or buried underground. Background technique [0002] PVC-U drainage pipes used in buildings or buried drainage must meet the needs of use, and must have a certain strength and rigidity, that is, product testing must pass the drop hammer impact test and tensile strength test. The existing general-purpose PVC-U drainage pipes still have insufficient impact resistance. In order to improve the impact resistance of PVC-U products (that is, to improve the toughness of the product), the usual method is to add different proportions of CPE and MBS to the product components. , ACR and other rubber elastomers for modification. However, when the rubber elastic body increases the toughness of the PVC-U drainage pipe to make it reach th...
