Problems solved by technology

However, the improvement of the impact resistance of CPE products is limited; high impact ACR and ACM can maintain a certain rigidity of the product and improve the impact resistance of the product, but simply adding CPE or ACM still cannot meet the high strength and high impact resistance of PVC pipes and fittings requirements

Abstract

The invention discloses a plum-blossom tube and a production process thereof, relates to the field of polymer materials, in particular, solves the problem that the impact resistance of the plum-blossom tube in the prior art is poor, and the plum-blossom tube includes the following components: PVC resin 40 ~60wt%, impact modifier 6~18wt%, composite stabilizer 1~7wt%, composite filler 25~35wt% and additive 2~6wt%; impact modifier includes ACR, MBS, CPE, ABS and Any two or more of EVA; composite stabilizers include one or more of calcium stearate, zinc stearate, and epoxidized soybean oil; composite fillers include calcium carbonate, titanium dioxide, diatomaceous earth, and rice Any two of shell powder; additives include lubricants, plasticizers, tougheners and paraffin. The plum-blossom tube of the invention has high impact resistance, certain tensile strength, tensile strength, stability, good appearance and transparency.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a quincunx tube and a production process thereof. Background technique [0002] Plum blossom tube is a kind of plum blossom-shaped communication pipe formed by PVC particles as the main material and other formulas through a unique mold, also known as honeycomb pipe. There are three types of five holes, seven holes and nine holes. Smooth, directly wearable optical cable, can save working hours, its structure is reasonable, high use value, long life, it is mainly used for communication cable sheath tube. [0003] PVC pipe has excellent physical properties, good corrosion resistance, chemical stability and flame resistance, etc., and is low in price. However, the intermolecular force of PVC is very strong, and the material is deformed after being subjected to low-temperature impact force, and the molecular structure is easily destroyed, resulting in poor impact resistance of PVC pi...
