Abstract

The invention discloses a PVC (polyvinyl chloride) hose which is prepared from the following raw materials in parts by weight: 10-20 parts of furfural resin, 7-11 parts of diisononyl phthalate, 4-8 parts of mannitol, 6-9 parts of naphthol, 2-4 parts of cobalt sesquioxide, 6-10 parts of fibrolite, 3-7 parts of black sand, 6-9 parts of celestite powder, 4-8 parts of bentonite, 3-6 parts of polytrimethylene terephthalate, 7-11 parts of iodine tincture, 5-10 parts of lithopone, 2-5 parts of oil of turpentine, 6-9 parts of organosilicone rubber compound and 15-25 parts of butadiene styrene rubber. The invention provides the PVC hose which is good in low temperature resistance, flexibility and antistatic property, can satisfy wear resistance and aging resistance in low-temperature transport and reduce fire damage, and is relatively low in ignition point.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC hose. Background technique [0002] Polyvinyl chloride pipe, also known as PVC pipe, is a pipe made of thermoplastic polymer polymerized by vinyl chloride monomer. It uses polyvinyl chloride resin as the main raw material, and adds an appropriate amount of anti-aging agent, modifier, etc. It is a material made by kneading, calendering, vacuum blister and other processes. PVC pipe has strong corrosion resistance and is easy to bond. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. However, PVC pipes, especially UPVC pipes, have poor heat resistance, and their tensile strength decreases in environments above 60°C, and ...
