Abstract

The invention relates to a PVC (Polyvinyl Chloride) tubular product, and in particular relates to a PVC (Polyvinyl Chloride)-M (Modified) shock-resistant tubular product. The tubular product is made of the following raw materials in parts by weight: 100 parts of a PVC resin, 6 parts of calcium powder, 3 parts of titanium dioxide powder, 6 parts of a stabilizer, 2 parts of stearic acid, 13 parts of a shock-resistant modifier, 1 part of PE (Polyethylene) wax, 0.5 part of an MBS (Methyl-methacrylate-Butadiene-Styrene) resin, and 4 parts of ACR (Acrylic Resin)-530. The PVC (Polyvinyl Chloride)-M (Modified) shock-resistant tubular product by the invention has good toughness and good shock resistance, can resist chemical corrosion, is improved in tension strength and elongation at break, and has difficulty in leaking or penetrating water, and cracking; and the MBS resin is added into the PVC tubular product for improving plasticization, so that the dispersion of inorganic matters and the processing fluidity of PVC melts are enhanced, and the low-temperature shock strength of the tubular product is improved.

Description

technical field [0001] The invention relates to a PVC pipe material, in particular to a PVC-M impact-resistant pipe material. Background technique [0002] Since the country organized and promoted the application of chemical building materials in a planned way in the early 1980s, the production and application of rigid PVC pipes have developed by leaps and bounds. An important use of rigid PVC pipes is for the construction of water supply and drainage pipe networks. In terms of water network construction, rigid PVC pipes have the advantage of longer service life than PE pipes, and the theoretical long-term strength of PVC is also higher than that of PE (PVC≥25MPa, PE≥10MPa). However, compared with PE, PVC is slightly "brittle", and it is easy to be injured when it is impacted. Therefore, how to improve the impact resistance and overcome the "brittleness" is a technical problem that must be solved for PVC pipes. [0003] The impact strength of rigid polyvinyl chloride prod...
