Preparation method of hard pipeline composite material

Abstract

The invention provides a preparation method of a hard pipeline composite material. The preparation method comprises the following steps: (1) preparing following raw materials: bamboo root fibers, PVC (Polyvinyl Chloride), glass fibers, resin, silicone oil, nano silicon dioxide, lime, sodium nitrate, pyrophyllite powder, cuprous chloride, cobalt chloride, polyvinyl alcohol and monoethanolamine; (2) mixing the bamboo root fibers, the PVC, the glass fibers and the polyvinyl alcohol and heating to 185 DEG C; stirring and mixing for not less than 15min and heating to 210 DEG C; keeping the temperature for 20 minutes to obtain a material A; (3) conveying the material A, the resin, the silicone oil, the nano silicon dioxide, the lime, the sodium nitrate, the pyrophyllite powder, the cuprous chloride, the cobalt chloride and the monoethanolamine into an extruder and extruding to form a base material; crushing the base material into grains to obtain the hard pipeline composite material. The invention provides a novel composite material for producing a hard pipeline and the produced pipeline has excellent performances; compared with an existing plastic pipeline, the hard pipeline has higher strength, better anti-ageing, corrosion-resisting and wearing-resisting performances and is safer.

Description

technical field [0001] The invention relates to the field of pipe production, in particular to a method for preparing a rigid pipe composite material. Background technique [0002] Plastic pipes are an important part of chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. Chemical building materials have made great progress and developed rapidly in our country. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe networks in the new century. [0003] The existing plastic pipes mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethyl...

Problems solved by technology

[0003] The existing plastic pipes mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes. The strength of the materials used in the existing plastic pipes is not high. After the pipe is made, the thickness of the pipe wall needs to be relatively large, otherwise it will not have sufficient strength and service life, and the anti-aging and anti-corrosion properties need to be further improved
