Abstract
An outdoor-type polypropylene compound is prepared from polypropylene resin, toughening modifier, mineral strengthening agent, coupling agent, assistant, optical stabilizer and colouring agent through dual-screw extruding. Its advantages are excellent mechanical performance and machinablity, and better resistance to light, high-temp and weather.
Description
The present invention relates to a kind of modified polypropene mixture that is used to make air conditioner outdoor shell and component and automobile instrument platen, collision bumper, inside gadget etc. and preparation method thereof.
Because plastics have characteristics such as density is little, corrosion-resistant, easy processing, thereby, sheet metal component on the conditioner (being corroded easily) is replaced by plastic component gradually, even novel overall plastic air-conditioning also emerges, and the plastic of conditioner sheet metal component is a development trend in the future.But plastics stand to expose to the weather and drench with rain, in the course of time, the mechanical property of material can decay gradually, become at last and can not use (referring to Chinese patent 1094420), that is to say and have plastic material aged problem, therefore must carry out modification to plastics, improve its ultraviolet light radiation capacity, satisfy the requirement of its outdoor use.
The present invention relates to the aging polypropylene composite of a kind of outdoor special-purpose fast light hot climate, the composition of its mixture (weight ratio %) is: acrylic resin 60-90, plasticized modifier 2-15, mineral toughener 2-30, coupling agent 0.2-1.5, processing aid 0.2-2, composite light stabilizer 0.2-3, tinting material 0.2-0.8.
The preparation method of outdoor-type polypropylene compound resisting against light radiation, high-temp, weather and ageing of the present invention is: the requirement by composite formulations takes by weighing material, mix through high-speed stirring, send in the twin screw extruder by the delicate metering feeder, through twin screw high speed shear, mixing, by head extrude, tie rod, air-cooled, pelletizing, drying and pack.

Processing aid in the aging polypropylene composite of fast light hot climate of the present invention is for effectively improving each component dispersiveness, reduce harmful friction, reducing the chemical substance that the interface adheres to, improves machine-shaping property when material produce and moulding.The mixture that comprises some fatty acid materials, fatty acid amide, silicone oil, silicone material and/or these compounds.Specifically can be solid paraffin, whiteruss, low molecular weight polyethylene, hard fat acid calcium, hard fat acid zinc, hard fat acid acid amides, the hard fat acid acid amides of methylene bis and N, the two hard fat acid acid amides of N-ethylene, silicone oil, polydimethyl silicone etc.
Composite light stabilizer in the aging polypropylene composite of fast light hot climate of the present invention is the mixture of dihydroxy benaophenonel, hydroxybenzotriazole, phosphite, hindered phenol, Resins, epoxy, metallic ion passivation agent, laurate, dialkyl dithiocarbamate, dialkyl dithiophosphate, hindered amine as light stabilizer, zinc oxide, carbon black and/or these compounds.Specifically comprise: UV-531, DOBP, UV-P, UV-326, UV-327, UV-328, UV-5411, UV-2908, ziram, photostabilizer 770, GW-540, Tinuvin622, Chimassorb944, UV-3346, zinc oxide, carbon black, 1010,168,619,626,1076,1024,7072 etc.
Specific embodiments of the present invention is provided by embodiment.
Example formulations sees Table 1, and its concrete operations step is basic identical, and promptly the first step mixes components such as acrylic resin, plasticized modifier, mineral toughener, coupling agent, processing aid, composite light stabilizer, tinting material in mixer; Second step was that said mixture is sent in the twin screw extruder by the feeder of delicate metering, through twin screw high speed shear, mixing, by head extrude, tie rod, air-cooled, pelletizing, drying and pack.Each section extruder temperature should be controlled between 190-260 ℃ among the preparation method of the present invention, is preferably between 200-220 ℃.
The performance perameter of the aging polypropylene composite of fast light hot climate of the present invention sees Table 2.
