Problems solved by technology

The application uses silicone processing aids to replace ACR and MBS, claiming that it improves the impact resistance of PVC pipe fittings and reduces production costs, but because of the lack of MBS, the produced products have poor compatibility and compatibility It is reflected in tensile impact strength, simply supported beam impact performance, and elongation at break
[0003] But the PVC pipe prepared in this way is opaque
It will bring a lot of inconvenience to daily use. For example, foreign matter may appear in the pipeline, which will affect the heat dissipation of the line. Since the PVC pipe is opaque during installation, it is impossible to see whether the line is neat or not.

Abstract

The invention discloses an impact-resistant toughened PVC pipe fitting and a preparation method thereof, the impact-resistant toughened PVC pipe fitting comprises the following raw materials by weight: 100 parts of SG-7 type PVC resin; 4.2 to 4.9 parts of an HL-60 type processing aid; 2-5 parts of an MBS-66 type impact modifier; 6.1-6.9 parts of a calcium-zinc heat stabilizer; 11.5 to 13.8 parts of PCC-P type ultrafine calcium carbonate; 2.1 to 2.8 parts of SR-240 type titanium dioxide powder; 4.2 to 4.9 parts of DS (Diethylhexyl Sulfate)-65 type dioctyl ester; and 0.6 to 0.8 part of an LA-W95type lubricant. The prepared impact-resistant toughened PVC pipe fitting solves the technical problems that a PVC pipe fitting produced in the prior art is low in impact resistance and toughness.

Description

technical field [0001] The present invention relates to the technical field of PVC pipe fittings production, more specifically, to an impact-resistant and toughened PVC pipe fitting, and more particularly to a preparation method for impact-resistant and toughened PVC pipe fittings. Background technique [0002] The Chinese patent application number is 201510562894.8, titled "An impact-resistant and toughened PVC pipe fitting and its preparation method" by adding PVC resin, silicone processing aids, stabilizers, ultrafine calcium carbonate, titanium dioxide, dioctyl, Seven raw materials for lubricants are used to prepare impact-resistant and toughened PVC pipe fittings at a high temperature of 125-135°C. The application uses silicone processing aids to replace ACR and MBS, claiming that it improves the impact resistance of PVC pipe fittings and reduces production costs, but because of the lack of MBS, the produced products have poor compatibility and compatibility It is refl...
