Description
Technical field
The present invention relates to a kind of polyblend, particularly relate to a kind of anti-aging resistant ABS-PVC plastic alloy.
Background technology
ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym of AcrylonitrileButadieneStyrene) is that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping.
ABS is the general thermoplastic engineering plastic grown up 1940's, it is the very outstanding plastics variety of a comprehensive mechanical property, not only there is good rigidity, hardness and processing fluidity, and there is high tenacity feature, can injection moulding, extrude or thermoforming.
Polyvinyl chloride (PVC) true qualities are that micro-yellow is translucent, glossy.Transparency is better than polyethylene, polypropylene, is worse than polystyrene, and different with auxiliary dosage, be divided into soft, rigid polyvinyl chloride, soft goods is soft and tough, and feel is glued, and the hardness of boardy product is higher than Low Density Polyethylene, and lower than polypropylene, in flexion, place there will be albinism.Common product: sheet material, tubing, sole, toy, door and window, wire outer skin, stationery etc.It is a kind of macromolecular material using a chlorine atom to replace a hydrogen atom in polyethylene.
ABS-PVC alloy is based on ABS resin and polyvinyl chloride resin, a kind of polymer blend with premium properties obtained by mechanical blending.
But current resistant ABS-PVC plastic alloy ageing resistance is not good.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of anti-aging resistant ABS-PVC plastic alloy, has good ageing resistance.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of anti-aging resistant ABS-PVC plastic alloy, is made up of by weight following component: 60-80 part ABS, 20-40 part PVC, 3-5 part stablizer, 2-3 part lubricant, 2-3 part softening agent, 0.5-1.5 part antiaging agent.
Described stablizer is organotin stabilizer, as Bis(lauroyloxy)dioctyltin or toxilic acid dioctyltin.
Described lubricant is stearic acid.
Described softening agent is epoxy soybean oil.
Described antiaging agent, be made up of by weight following component: 30-50 part 4, the two octadecyl of 4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 30-50 part 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, 10-30 part thio-2 acid.
4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), No. CAS: 96-69-5, English name: 4,4'-Thio-bis (6-tert-butyl-m-methylphenol).
1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, No. CAS: 1843-03-4,4,4', 4''-(1-methyl-1-propanyl-3-ylidene) tris [2-(1,1-dimethylethyl)-5-methyl-Phenol.
The two octadecyl of thio-2 acid, English name: Distearylthiodipropionate, No. CAS: 693-36-7.
Two to 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and thio-2 acid octadecyl is uniformly mixed, this antiaging agent can be obtained.
Industry universal method can be adopted to be prepared anti-aging resistant ABS-PVC plastic alloy of the present invention, and such as: take each component by proportioning, after mixing, melting mixing, extruding pelletization, namely obtain described anti-aging resistant ABS-PVC plastic alloy.
Concrete, polyvinyl chloride resin, stablizer, softening agent, lubricant can be added mixing machine at 75-85 DEG C of mixing 4-8 minute, be cooled to 35-45 DEG C, add ABS resin and antiaging agent again, mixing 15-25 minute, sends into granulation in twin screw extruder, barrel temperature 170-190 DEG C, screw speed 15-25r/min, namely obtains described anti-aging resistant ABS-PVC plastic alloy.
Obviously, in the present invention for improving other performances of product, other auxiliary agents can also be added adaptively, as fire retardant, tinting material and static inhibitor etc.
Contriver is drawn by great many of experiments, by 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and the two octadecyl three kinds of antiaging agents of thio-2 acid carry out reasonable composite use, synergy, antiageing effect is obvious.
Anti-aging resistant ABS-PVC plastic alloy of the present invention, combine the excellent specific property of bi-material, both had ABS resin shock-resistant, low temperature resistant, be easy to the features such as forming process, there is again polyvinyl chloride resin good flame resistance, good rigidly, the feature that corrosion-resistant, electrical insulation capability is excellent.Office equipment, household electrical appliance, electronic apparatus and automotive field can be widely used in.And anti-aging resistant ABS-PVC plastic alloy of the present invention has outstanding heat aging performance, uses under being adapted at thermal extremes environment.
