Titanate coupling agent modified polyvinyl chloride pipe material and manufacturing method thereof

Abstract

The invention discloses a titanate coupling agent modified polyvinyl chloride pipe material and a manufacturing method thereof, which belong to modified polyvinyl chloride novel polymer composite materials. The titanate coupling agent modified polyvinyl chloride pipe material makes use of a titanate coupling agent modified polyvinyl chloride composite material, and comprises the following components in part by mass: 100 parts of polyvinyl chloride resin SG-5, 4 to 5 parts of stabilizing agent, 6 to 8 parts of impact modifier, 0.8 to 1.0 part of lubricant, 1.0 to 1.5 parts of titanate coupling agent, 3 to 5 parts of flame retardant, 10 to 40 parts of light calcium carbonate filler, and a proper amount of pigment. The pipe material has the following properties that: the tensile yield pressure is 50 MPa, the insulation resistance is 1.33*1,011 ohm, no crack is generated when the pipe material is bent for 270 degrees, the self-extinguishing time is 1 S, and the pipe material accords with the 'standard for safety evaluation of equipment and protective materials in drinking water system'. The pipe material has the advantages of excellent mechanical properties, flame retardant property, weathering resistance, insulating property and processability, high smoothness and high performance price ratio, and is energy-saving, sanitary and environmentally-friendly.

Description

technical field [0001] The invention relates to a novel modified polyvinyl chloride polymer composite material and a manufacturing method, in particular to a polyvinyl chloride pipe material modified by a titanate coupling agent and a manufacturing method. Background technique [0002] As we all know, the application of PVC pipes began in the 1930s and has a history of more than 70 years. It is a product with relatively mature production technology, experimental testing, standardization, design and construction specifications. Because of its good cost performance and excellent physical and mechanical properties, it has been widely used in engineering, and it is still the most widely used plastic pipe, accounting for about 60% of the entire plastic pipe market. [0003] The production of polyvinyl chloride pipes in China started in the 1950s, but before the 1980s, compared with the international advanced level, there was a big gap in both the standard system and the processin...

Problems solved by technology

[0009] Since the molecular structure of polyvinyl chloride contains as much as 56% chlorine, the intermolecular force is large, the molecular chain is rigid, and the crack resistance and impact resistance are poor, especially at low temperature; therefore, both domestic and foreign resin manufacturers Or pipe manufacturers, professional research departments have done a lot of research work
