Abstract
The invention relates to a high-impact-resistance polyvinyl chloride pipe material, and relates to the technical field of plastic processing. The pipe material is composed of the raw materials of, by weight, 80 parts of polyvinyl chloride resin, 5-10 parts of an impact modifier, 5-10 parts of phosphite, 0.5-5 parts of a stabilizer, 2-5 parts of a lubricant, 1-5 parts of light carbon carbonate, and 1-2 parts of a brightening agent. The system satisfies a condition to make rigid organic particles yield, such that a synergistic effect is provided. Also, PMMA is a polymer with relatively high rigidity and high strength. With the addition of PMMA, certain contribution is made to the strength of the material.
Description
Technical field
The present invention relates to the polychloroethylene pipes of a kind of high-impact performance, belong to technical field of plastic.
Background technology
Pvc pipe is plastic conduit conventional at present, has lightweight, corrosion-resistant, intensity height, weatherability and good flame resistance, the advantages such as price is relatively low.Existing PVC produces, and mainly by adding chlorinated polyethylene as auxiliary agent, it is relatively low that such mode of production is easily caused polychloroethylene pipes yield.
But PVC-U (PVC-U) pipeline fragility is relatively big, and during particularly in low temperature, impact strength is low, and anti-cracking performance is poor, bring more problem and inconvenience to installation and use.
Therefore we need one to possess high impact-resistant polychloroethylene pipes, while it should keep the elastic modelling quantity of tubing, also to improve the pliability of tubing, greatly facilitate carrying, transport, improve the safety of conduit running；Also to improve the yield of product simultaneously.
Summary of the invention
Not enough according to prior art, the technical problem to be solved is: provide the polychloroethylene pipes of a kind of high-impact performance, improves the rigidity of material, and the coordination plasticizing performance of material obtains raising effect simultaneously, improve the erosion-resisting characteristics of tubing simultaneously, improve product yield.
The technical solution adopted for the present invention to solve the technical problems is: provides the polychloroethylene pipes of a kind of high-impact performance, is made up of the raw material of following parts by weight:
Polyvinyl chloride resin: 80 parts；
Impact modifier: 5-10 part；
Phosphite ester: 5-10 part
Stabilizer: 0.5-5 part；
Lubricant: 2-5 part；
Precipitated calcium carbonate: 1-5 part；
Brightening agent: 1-2 part.
Described lubricant is any two or two or more mixture in stearic acid, paraffin, microwax, OPE, PE wax.
Described stabilizer is compound stannum stabilizer.
Described polyvinyl chloride resin is the degree of polymerization is the polyvinyl chloride resin of 1400 to 1600.
Described impact modifier is ACM-M, it is to be core by the butyl acrylate body cross-linked and the good methacrylate body of the PVC compatibility is shell, then the MBS of the macromolecular elastomer with multiple structure prepared by proper proportion copolymerization with vinyl chloride or butadiene content more than 70%.
The invention has the beneficial effects as follows: the invention provides a kind of modified polyvinyl chloride pipe composition, adopt the interpenetrating network copolymer (ACM) of the HDPE of slight chlorination and acrylate or/and MBS is as impact modifier, material also plays the effect of coordination plasticizing while improving material stiffness, and the hot strength of material and impact strength obtain and improve to a certain extent.The yield of product can also be improved simultaneously.
