Problems solved by technology

[0003] However, there is no environmentally friendly special material for polypropylene pipes at present, and the plastic industry always adds antibacterial agents to polypropylene raw materials to prepare antibacterial polypropylene, resulting in high cost and unstable quality.
Although it has antibacterial function, the antibacterial agent is highly toxic and the antibacterial effect is not durable, and the antibacterial agent in polypropylene is dispersed unevenly, which seriously affects the mechanical properties of the product, which limits the application of polypropylene to a certain extent.

Abstract

The invention discloses an antibacterial toughened polypropylene tube material for buildings, and a preparation method thereof. The basic formula of the tube material comprises, by weight, 25-35 parts of polypropylene, 14-22 parts of coupling agent modified antibacterial fibers, 5-16 parts of a monofunctional group epoxy compound, 10-18 parts of modified rubber powder, 4-12 parts of a maleic anhydride grafted copolymer, 6-14 parts of a rare earth coupling agent, 8-15 parts of a coupling agent modified filler and 1-4 parts of an antioxidant. The preparation method comprises the following steps: sending uniformly mixed materials into the loading hopper of a double screw extruder hopper, and carrying out double screw melting and extrusion to obtain the polypropylene tube material. The antibacterial toughened polypropylene tube material prepared in the invention has high mechanical strength, good toughness and good antibacterial effect, and is suitable for the fields of building water tubes and domestic tap water tubes.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to an antibacterial and toughened polypropylene pipe for construction and a preparation method thereof. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials. Polypropylene itself does not have antibacterial effect, so the development of new polypropylene materials with antibacterial properties has very important practical significance for environmental protection and people's health. [0003] However, there is no special material for environmentally friendly polypropylene pipes at present. The plastic industry always adds antibacterial agents to polypropylene raw materials to prepare antibacterial polypropylene. The resulting products have high cost and...
