Abstract
The invention relates to a flame retardant antistatic toughening PVC (Poly Vinyl Chloride) pipe for methane. The pipe is produced and prepared by adding a nanometer strengthening and toughening material and an antistatic and fire retardant material to polyvinyl chloride resin. According to the flame retardant antistatic toughening PVC pipe for methane, the coordinative antistatic effects of alkyl sulfonic acid and conductive carbon black as well as the coordinative flame retardant smoke suppression effects of antimonous oxide, and tricresyl phosphate or aluminium hydroxide are fully utilized, so that the purpose of safely using the flame retardant antistatic toughening PVC pipe for methane in the methane transportation filed can be achieved along with the outstanding toughening and strengthening material. Compared with the traditional plastic pipe, the flame retardant antistatic toughening PVC pipe for methane has relatively high durable performance and relatively high safety, is specifically suitable for the fields of outdoor branch pipes for methane and home-entering introducing pipes, can effectively improves the safety in use, reduces the possibility that a pipeline is cracked and leaks gas due to an accidental impacting and the possibility that the pipeline causes an antistatic fire due to the reduced whole antistatic effect, cannot fuel the fire in case the fire occurs, generates little smoke, and reduces the risk of the fire to the affected residents and firefighters.
Description
Technical field
The present invention relates to a kind of biogas flame-retardant and anti-static toughening PVC tubing, relate to specifically one and utilize nano level enhancing, toughening material, antistatic, fire retardant material, flame-retardant and anti-static pvc pipe material for the biogas of manufacture.
Background technology
Pvc pipe material major ingredient is polyvinyl chloride (PVC) RESINS, adds in addition some auxiliary agents to reach heat-resisting, toughness, erosion-resisting characteristics etc.Pvc pipe road is widely used in plumbing field, has acidproof, alkaline-resisting, corrosion-resistant, intensity advantages of higher.But pvc pipe road impact-resistance is poor, and flame retardant resistance is inadequate, burning has smog and produces, and not antistatic, these defects are unfavorable for the application of pvc pipe road in biogas and natural gas transport field.
Summary of the invention
The object of the invention is to overcome the defect of above-mentioned prior art, a kind of biogas flame-retardant and anti-static toughening PVC tubing that simultaneously possesses good antistatic effect, flame retardant properties and smoke suppressing is provided.
