Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of scratch resistance mill type shock resistance polychloroethylene pipes and preparation method thereof.
Background technology
Find after deliberation, in the process material modification of PVC prescription basis, and in conjunction with advanced complete processing, can produce this impact-resistant modified polyvinyl chloride tube material that has intensity and toughness concurrently.The erosion resistance that impact-resistant modified polyvinyl chloride tube material has is lightweight, friction resistance is little, ring stiffness is high, good, weather resistance, higher cost performance, and the characteristics that do not need often replacing and safeguard, be widely used in construction drainage, blowdown, and the field such as chemical engineering.This class tubing is main mainly with improving its shock resistance, when conveying contains the blowdown liquid in factory, mine of waste residue, can because of the waste residue in the liquid long-time with the contacting and friction of polychloroethylene pipes, make the polychloroethylene pipes attenuation until wear and tear.
The at present domestic research that has part unit to set foot in the scrape abrasion resistance polychloroethylene pipes, the scrape abrasion resistance of improving the polyvinyl chloride pipe material generally is to select quality harder, structure is unsuitable destroyed, and the mineral filler through coupling processing joins in the polyvinyl chloride, as has the calcium carbonate of whisker structure, although barium sulfate etc. can improve the scrape abrasion resistance energy of pvc material, but crystal whisker materials is more crisp, the effect that work in-process such as is sheared at the mechanical force is easily fractureed, cause the scrape abrasion resistance of polyvinyl chloride pipe material can be still not high, can not satisfy the demand in high-impact high abrasion tubing market.
Chinese patent CN102020782A is the patent that China Petrochemical Corp. has applied for.This patent relates to a kind of functional filler that improves plastics, rubber wear-resisting performance that has.The contriver finds and will add in the polyvinyl chloride pipe material according to the wear-resisting properties-correcting agent that Chinese patent CN102020782A makes, and can effectively improve the wear resisting property of polychloroethylene pipes, has reduced as few as possible again the impact on other performance of polyvinyl chloride pipe material.
Summary of the invention
The technical problem to be solved in the present invention is: the deficiency for above-mentioned prior art exists, a kind of scratch resistance mill type shock resistance polyvinyl chloride pipe material and preparation method are provided, and it has good wear resistance and impact resistance.
