Abstract
The invention provides a low-water absorption enhanced PA/ASA alloy. The low-water absorption enhanced PA/ASA alloy is prepared from such components in parts by weight as 50-60 parts of PA polyamide resin, 10-20 parts of acrylonitrile-styrene-acrylate (ASA) grafted copolymer, 20-30 parts of glass fibers, 2-5 parts of organic silicon, 0.02-0.05 part of antioxidant 1098, 0.02-0.05 part of antioxidant 168, 0.5-2 parts of thermal stabilizer, 1-3 parts of compatible flexibilizer, 0.5-2 parts of lubricant and 1-2 parts of initiator. The low-water absorption enhanced PA/ASA alloy has the advantages of low water absorption, high stability, high material compatibility, high toughness and the like.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of low water absorption and strengthen PA/ASA alloy.
Background technology
PA66 is translucent or opaque oyster white particle, has the features such as thermoplasticity, lightweight, good toughness, chemicals-resistant and good endurance, is generally used for the products such as auto parts, mechanical part, electronic apparatus.But also there is shortcoming, as high in water-intake rate, poor dimensional stability, contact meeting thermolysis etc. for a long time with oxygen.
ASA is vinyl cyanide-acrylate-styrene copolymer, is the shortcoming for ABS weathering resistance difference and the engineering plastics developed.It has good weathering resistance, even if be exposed to outdoor ultraviolet, humidity for a long time, drench with rain, under illumination and ozone condition, physical property also can be kept to stablize without application.Be particularly suitable for not application directly to use out of doors.Be widely used in automobile, electric, the field such as daily necessities, outdoor decoration material.If PA and ASA is made blend alloy, toughness, weathering resistance, the stability of the existing ASA of obtained alloy, have again weak acid resistant alkalescence and the thermotolerance of PA.
Conventional enhancing PA/ASA is that the bad and inner generation stress of consistency likely can appear in non-crystalline resin because PA is crystalline resin ASA.
Silicone resin hydroxyl shrink polymerization crosslinking under the effect of initiator forms reticulated structure, forms waterproof layer; Dispersion agent by silicone resin in PA/ASA matrix material evenly dispersion; And silicone resin and glass fibre cohesiveness good, PA/ASA matrix material is risen and doubles enhancement.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, providing low water absorption PA/ASA to strengthen alloy, this invention product not only has the advantages such as excellent mechanical property is weather-proof, has the feature of low water suction simultaneously.
The technical solution used in the present invention is as follows: a kind of low water absorption strengthens PA/ASA alloy, its each moiety and parts by weight are: PA polyamide resin 50-60 part, ASA vinyl cyanide-vinylbenzene-acrylate graft copolymers 10-20 part, glass fibre 20-30 part, organosilicon 2-5 part, oxidation inhibitor 1098 0.02-0.05 part, irgasfos 168 0.02-0.05 part, thermo-stabilizer 0.5-2 part, compatible toughening agents 1-3 part, lubricant 0.5-2 part, initiator 1-2 part.
Further prioritization scheme is described glass fibre is short glass fiber, and length is 3-5mm, and diameter is 5-8 μm, is import hydrolysis short fiber.
Further prioritization scheme is described thermo-stabilizer is dimethyl dimercapto 2-ethyl hexyl ethanoate tin.
Further prioritization scheme to be described irgasfos 168 be vapour Bagong department 1098: N, N'-two-(3-(3,5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine 168: three [2.4-di-tert-butyl-phenyl] phosphorous acid ester.
Any one of further prioritization scheme to be described lubricant be polyvinylpyrrolidone or polyacrylamide or polyoxyethylene or polyvinyl alcohol.
The further prioritization scheme multiple graft copolymer that to be described compatible toughening agents be in ASA-G-MAH or EPDM-G-MAH system.
Further prioritization scheme is described initiator is N-xylidine.
Preparation method of the present invention comprises the following steps:
Add blended by the raw material that weighs up by different step, in homogenizer, mixing amounts to 10min, then deliver to twin screw extruder melting, mixing, extrude.Fiberglass fiber is added by side forced feeding system meters.Each section of extruder temperature is 220-270 DEG C, then through cooling, pelletizing, drying, finally packs, and obtains product of the present invention.
Compared with prior art, its beneficial effect is in the present invention: (1) product of the present invention adopts organosilicon and the anti-hydrolysis staple fibre of initiator to reach the feature of low water absorption; (2) the present invention adopts dimethyl dimercapto 2-ethyl hexyl ethanoate tin to reach a high temperature stabilising effect; (3) product of the present invention adopts initiator, further raising dispersion of materials homogeneity and surperficial water tolerance (4) product of the present invention use multiple graft copolymer in ASA-G-MAH or EPDM-G-MAH system as compatible toughening agents, reach material compatibility high, internal stress is little, and toughness is high thus improve product use range.
