Description
Technical field
The present invention relates to a kind of polychloroethylene pipes composition of methyl methacrylate polymer modification, belong to technical field of plastic.
Background technology
The advantages such as pvc pipe is plastic conduit at present commonly used, has lightweightly, corrosion-resistant, and intensity is high, weathering resistance and good flame resistance, and price is lower.But rigid polyvinyl chloride (PVC-U) pipeline fragility is larger, and especially when low temperature, shock strength is low, and anti-cracking performance is poor, brings more problem and inconvenience for installation and use.In this case, the domestic high impact-resistant polychloroethylene pipes (PVC-M) of in succession having developed, PVC-M have improved the snappiness of tubing in the Young's modulus that keeps PVC-U tubing, greatly facilitate carrying, transportation, the security that improves conduit running.Present domestic PVC-M tubing generally uses MBS (MBS), polyacrylate(s) (ACR), chlorinatedpolyethylene (CPE) etc. to improve the erosion-resisting characteristics of PVC, although but a large amount of impact modifiers add the erosion-resisting characteristics that has improved system, also often sacrifice the rigidity of material, be difficult to make material to reach rigidity-toughness balanced preferably.To use more CPE as example, though CPE is increased the toughness of material, but it is comparatively harsh that processing conditions becomes, and its impact property is still not high at low temperatures, be difficult to reach rigidity-toughness balanced preferably, therefore need to seek a kind of better modification approach satisfies material to the requirement of erosion-resisting characteristics.
Summary of the invention
Not enough according to prior art, technical problem to be solved by this invention is: the polychloroethylene pipes composition that a kind of methyl methacrylate polymer modification is provided, improve the rigidity of material, the coordination plasticizing performance effect of being improved of material simultaneously, tensile strength and the shock strength of material are improved.
The technical solution adopted for the present invention to solve the technical problems is: a kind of polychloroethylene pipes composition of methyl methacrylate polymer modification is provided, it is characterized in that being comprised of the raw material of following parts by weight:
Polyvinyl chloride resin: 100 parts;
Impact modifier: 8-16 part;
Rigid resin: 1-9 part;

Tinting material: 0.01-1.0 part.
Described polyvinyl chloride resin is that the polymerization degree is 800 to 1200 polyvinyl chloride resin, and preferred degree of polymerization is 1000 polyvinyl chloride resin.
Described impact modifier is ACM-M, be by crosslinked butyl acrylate body be core, with the good methacrylic ester polymer of PVC consistency be shell, the macromolecular elastomer with multilayered structure that makes by the suitable proportion copolymerization with vinylchlorid again, or the MBS (MBS) of butadiene content more than 70%.
Described stablizer is organotin stabilizer, preferable methyl tin mercaptides MS1928.
Described rigid resin is methyl methacrylate polymer, and consumption is 1-9 part, preferred 3-5 part.
Described lubricant is any two or more mixture in stearic acid, paraffin, Microcrystalline Wax, oxidized polyethlene wax, PE wax.
Described weighting agent is active superfine calcium carbonate, and preferred order number is greater than 1000 purpose activated Calcium carbonates.
Described tinting material is titanium dioxide or carbon black.
The polychloroethylene pipes preparation method of composition of this PMMA modification is:
First rigid resin is fully mixed with impact modifier, then polyvinyl chloride resin, thermo-stabilizer, lubricant, tinting material and rigid resin and impact-resistant modified agent composition are mixed in high low speed mixer, mixing temperature is 100-120 ℃, mixing time is about 10-20 minute, then above-mentioned compound is mixed to 40 ℃ of left and right dischargings of temperature in low-speed mixer, is polychloroethylene pipes composition of the present invention.
The invention has the beneficial effects as follows: the polychloroethylene pipes composition that the invention provides a kind of PMMA modification, adopt the HDPE of slight chlorination and the interpenetrating network copolymer of acrylate (ACM) or/and MBS as impact modifier, rigid resin methyl methacrylate polymer (PMMA) is as the modified synergic agent, test shows, adopt a small amount of rigid resin modified synergic, also material is played the effect of coordination plasticizing when improving rigidity of material, the tensile strength of material and shock strength get to a certain extent and improve.Method is first impact modifier to be mixed with rigid resin PMMA, and then join in PVC, the advantage of mixing like this is: PMMA is distributed in impact modifier uniformly, and both contact probabilities and contact area increase greatly, and then have improved the consistency of ternary blends; Greater than PMMA, when joining this blend in the PVC system, this system can satisfy makes Rigid Organic Fillers produce the condition of surrender, thereby plays the coordination plasticizing effect due to the massfraction of impact modifier; Because PMMA is the higher polymkeric substance of rigidity, intensity own is higher simultaneously, and its intensity to material that adds also plays certain contribution function.
