Abstract
The invention discloses a polyvinyl chloride toughening modifier, which comprises 1.0 to 2.0 portions of methylmethacrylate butadine stryrene copolymer which is also called MBS, and 6 to 15 portions of acrylates impact modifier which is also called ACR impact modifier; and the portion of the compositions is weight portion. The polyvinyl chloride toughening modifier has good toughening and modification effects on polyvinyl chloride.
Description
Technical field
The invention belongs to the plastic pipe technical field, be specifically related to a kind of polyvinyl chloride toughening modifier.
Background technology
Polyvinyl chloride is one of most widely used thermoplastics, and the annual consumption of present global polyvinyl chloride is about 3,000 ten thousand tons, and wherein about 1/3rd are applied to pipe part.Though be faced with the competition of other plastic conduits, the polyvinyl chloride pipeline system remains the plastic conduit of consumption maximum so far.
For a long time, the PVC water supply line was once once becoming the first-selection of China.As if enter 21 century, traditional polychloroethylene pipes is in the face of many rivals, and the PE tubing that especially has excellent toughness and anti-impact of water hammer ability except carrying out feverish price war, has not just had other countermeasure except controlling cost.
The destruction of plastic conduit has two kinds of forms, the one, ductile failure, the one, brittle rupture usually.Compare the easier generation brittle rupture of common hard polyvinyl chloride pipeline with the PE pipeline.The PE pipeline is why very fast to be accepted by people, exactly because its excellent toughness.So will carry out suitable toughening modifying to rigid polyvinyl chloride, comprise the properties-correcting agent that adds suitable kind and component and adopt suitable complete processing, make the PVC after the modification brittle rupture no longer occur, to widen the generation of its use range and minimizing accident as far as possible.
Summary of the invention
The purpose of this invention is to provide a kind of polyvinyl chloride toughening modifier that has better toughening modifying effect for polyvinyl chloride.
Realize a kind of polyvinyl chloride toughening modifier of the object of the invention, comprising:
MBS is also referred to as MBS:1.0 part to 2.0 part;
Acrylic ester impact-resisting modifier is also referred to as the ACR impact modifier: 6 parts to 15 parts;
The umber of above-mentioned each component all is weight parts.
In the technique scheme, also comprise 0.6 part of thermo-stabilizer to 1.6 parts of weight parts.
In the technique scheme, described thermo-stabilizer is organotin, mercaptan antimony or mercapto-carboxylic ester antimony.
In the technique scheme, described organotin is thiol methyl tin, di-n-butyltin dilaurate, toxilic acid dibutyl tin, butyl maleate dibutyl tin, toxilic acid dioctyltin or S, S '-dimercapto 2-ethyl hexyl ethanoate dioctyltin.
In the technique scheme, also comprise 0.7 part of the external lubricant that is used for reducing frictional force between material and the extraneous equipment to 1.3 parts of weight parts in the course of processing; Be used for reducing 0.7 part of internal lubricant of material frictional force each other to 1.0 parts of weight parts in the course of processing.
In the technique scheme, described external lubricant is stearic acid or stearate; Described internal lubricant is polyethylene wax or whiteruss.
In the technique scheme, described stearate is calcium stearate, barium stearate, Magnesium Stearate, cadmium stearate, Zinic stearas or lead stearate.
In the technique scheme, described acrylic ester impact-resisting modifier is that the multipolymer with alkyl acrylate and methyl methacrylate or acrylate and methyl methacrylate is a shell, the elastomerics that is cross-linked to form with butyl acrylate is the hud typed multipolymer that nuclear forms.
In the technique scheme, also comprise 0.6 part of tinting material to 2.0 parts of weight parts; Described tinting material is titanium white, titan yellow, Zh 1, zinc-iron pigment, colcother, cobalt blue, chromoxide green, spinel is green, Huang is plumbous, at least a in the chromium tangerine, chrome vermillion.
In the technique scheme, comprise that also 1.0 parts to 1.2 parts parts by weight of acrylic ester class modifiers are also referred to as the ACR modifier.
In the technique scheme, described esters of acrylic acid modifier is the multipolymer of methyl methacrylate and acrylate.
The positively effect that the present invention has:
(1) among the present invention, MBS and impact modifier especially together join in the polyvinyl chloride resin with acrylic ester impact-resisting modifier, and when blending and modifying, the two has the technique effect of coordination plasticizing.The tubing that adopts alloy of the present invention to make, its shock resistance effect are better than the tubing that single adding MBS or described acrylic ester impact-resisting modifier are made.
(2) among the present invention, adding the esters of acrylic acid modifier also is the ACR modifier, can obviously shorten fusion time, accelerates fusion, promotes plasticizing, to extruded product its balancing torque is improved, and makes its plasticizing evenly; To calendered goods, add the esters of acrylic acid modifier and can overcome chill mark, help material bag roller, reduce bubble; In addition, from the outward appearance of goods, the esters of acrylic acid modifier can obviously improve the surface gloss of goods, makes goods seem smooth exquisiteness.
(3) utilize the polyvinyl chloride alloy of product modification of the present invention, have the scope of application of broad, aspects such as the sheet material of preparation or the dimensional precision of tubing, whiteness, weathering resistance all are better than rigid polyvinyl chloride; Especially aspect shock resistance, considerably beyond the rigid polyvinyl chloride products made thereby; For example, when 22 ℃ of envrionment temperatures, be that 110mm, wall thickness are the high speed impact test of dropping hammer of the tubing of 4.2mm to diameter: allow 10 kilograms drop hammer from 20 meters height, freely fall, pound on tubing, check the damage effect of tubing.After high speed impact test that the tubing that adopts traditional rigid polyvinyl chloride to make is dropped hammer, tangible brittle rupture takes place in tubing; And do same test at the tubing that the polyvinyl chloride alloy that adopts product modification of the present invention is made, tangible ductile failure then takes place, no brittle rupture; But the intensity of the tubing that the polyvinyl chloride alloy of product modification of the present invention is made is basic identical with the tubing that adopts traditional rigid polyvinyl chloride to make; So the tubing that adopts the polyvinyl chloride alloy of product modification of the present invention to make is keeping the high-intensity while, toughness has had the variation of matter.Its good toughness can greatly be avoided in the construction process tubing destruction that meets accident, and the ability that simultaneously good toughness and higher elongation at break can improve the anti-impact of water hammer of tubing system again is in operation this tubing system and becomes safer reliable.Traditional PE tubing is formal because have good toughness, has used low 1.25 the total coefficient of performance that reaches when design.Equally, abroad, toughened modified polyvinyl chloride alloy industry, total coefficient of performance of 1.4 or 1.6 is formally adopted, and has done clearly regulation in standard.When total coefficient of performance dropped to 1.6 or 1.4 by 2, tube wall thickness was approximately than original thin 20% to 30%.This product material expense is than common rigid polyvinyl chloride product height per ton about 30% to 40%, both take all factors into consideration, it is high approximately by 20% that the tubing of the polyvinyl chloride alloy production of product modification of the present invention and traditional rigid polyvinyl chloride product of same nominal outside diameter and nominal pressure are compared the price of rice, but still be starkly lower than the price of PE tubing.In a word, the over-all properties of the polyvinyl chloride alloy of product modification of the present invention has reached even has surpassed international like product at some aspect of performance.
