Self-layering, antifouling and easily-cleaned plastic tube and production method thereof

Abstract

The invention discloses a self-layering, antifouling and easily-cleaned plastic tube. Raw materials of the plastic tube comprise, by weight, 1-5 parts of self-layering antifouling master batches and 100 parts of polypropylene random copolymer particles; and raw materials of the self-layering antifouling master batches comprise, by weight, 1-5 parts of a fluorine-silicon low surface energy polymer,0.1-2 parts of a compatibilizer and 100 parts of polypropylene particles. The fluorine-silicon low surface energy polymer has antifouling, hydrophobic and oleophobic properties, so the plastic tube produced by using the fluorine-silicon low surface energy polymer has a large water contact angle, a large oil contact angle and a small static friction coefficient, thereby dirt, grease and bacteria are not prone to be enriched in the tube, and the plastic tube has low adhesion to stains, has a self-cleaning property during flow washing, and can be applied to various fields of water supply and drainage, urban and rural water supply and drainage, and industrial fluid transportation.

Description

technical field [0001] The invention relates to the field of preparation of plastic pipes, in particular to a self-layering antifouling and easy-to-clean plastic pipe and a preparation method thereof. Background technique [0002] PP-R pipes are random copolymerized polypropylene pipes, which have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, simple construction and maintenance, and long service life. They are widely used in building water supply and drainage, urban and rural water supply and drainage, and industrial fluids. Transportation, agricultural irrigation and other fields are the mainstream products in the current market. However, the pipeline has no self-cleaning and antifouling functions. Under special circumstances, a large amount of pollutants are easily attached to the pipe wall, which causes bacteria to grow and becomes a gathering place for secondary pollution of water quality.

Problems solved by technology

The antibacterial material is mainly to add antibacterial agents such as silver or zinc oxide during the extrusion process of PP-R pipes to achieve the purpose of antibacterial pipes, but the addition of antibacterial agents only works on the surface of the pipe. Once the surface of the pipe is covered by domestic garbage and grease , the effect of the antibacterial agent is greatly reduced, and it cannot play a suitable antibacterial effect.

The anti-fouling and easy-cleaning coating technology mainly uses low surface energy fluorine-containing and silicon-containing coatings, which are coated on the inner layer of the pipeline to reduce the adhesion between dirt and the inner layer of the pipeline and achieve the purpose of anti-fouling and easy-cleaning. Difficult, high cost, difficult to apply on a large scale
