Description
Technical field
The invention belongs to modified plastics formulation art, particularly a kind of flame-proof anti-aging polypropylene for engineering machinery non-bearing gadget and make the polyacrylic preparation method of this flame-proof anti-aging.
Background technology
Manufacturing field in engineering machinery, at present except a small amount of inside gadget, is adopt hardware substantially.Such as on board a dredger, back cover plate generally adopts steel plate 3/Q235B material, and use the method manufacture of flat board+punching to form, the length and width size of larger back cover plate can reach 1 meter, and weight reaches more than 20 kilograms; And the Abdeckteil majority on it is the sheet metal component of a series of die stamping obtained by molding of high price exploitation, material many employings Q195 steel plate, the large person of gadget length and width size is more than 2 meters, and What is more reaches 4 ~ 5 meters, and weight reaches tens of kilograms and even crosses hundred kilograms.But in the middle of these gadgets, there is the Main Function of quite a few gadget to be attractive, decorative and every grey dust-break, as back cover plate used on aforementioned excavator, it is installed on revolving platform of excavator bottom, Main Function stops that ground sandstone, earth, rubbish incidental etc. enter revolving dial top and result in blockage, pollute Hydraulic Elements, pipe fitting, engine etc. exactly, and to be loaded on the front shroud before fuel tank be only prevent dust from entering pollution fuel tank, play the effect of aesthetic appeal simultaneously.From service requirements and the function of these gadgets, do not need to adopt metal foil gadget completely, and use metallic steel plate also to there is many drawbacks: one is because the density of steel is large, gadget Heavy Weight, cause the power consumption of engineering machinery to remain high, the energy-saving and emission-reduction advocated with current country, low-carbon (LC) are produced and are disagreed; Two is that during work, the vibrations of machine are very large, and the shock resistance of metallic substance is poor, and sound absorption qualities is bad causes noise pollution serious because engineering machinery environment is in the course of the work very severe; Three is that metallic substance is not corrosion-resistant, oil resistant, acid and alkali-resistance and water-proof anti-aging inequality, gadget surface needs to spray paint antirust, further increase the cost of gadget, and gadget is often swiped and is made the peeling paint on surface in the Working environment that engineering machinery is severe, add the etch of rainwater, greasy dirt, soda acid etc. result in soon gadget get rusty, damaged and lost efficacy; Four is due to gadget weight, cause assembly and disassembly operations extremely inconvenient, and the cost of gadget is also high.Therefore seek that a kind of weight is lighter, cost is lower, the feature of environmental protection is better, erosion resistance is stronger, to manufacture non-bearing inner and outer decorative parts that easy type material carrys out alternative metals material produce manufacturing engineering machinery as imperative in cover plate, back cover plate, Abdeckteil, greatly enclosing element etc.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, provide a kind of lightweight, cost is low, the feature of environmental protection good, erosion resistance is strong, the flame-proof anti-aging polypropylene for engineering machinery non-bearing gadget of the manufacturing and the easy high strength weather of assembly and disassembly operations.
The technical scheme realizing the object of the invention is: a kind of flame-proof anti-aging polypropylene for engineering machinery non-bearing gadget, is characterized in that: be made up of the raw material of following mass fraction proportioning:

Described in technique scheme, anti-aging weather resisting agent is made up of oxidation inhibitor and uv-absorbing agent.
Antioxidant described in technique scheme is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
Uv-absorbing agent described in technique scheme is (2 ˊ-hydroxyl-3 ˊ-tertiary butyl-5 ˊ-aminomethyl phenyl)-5-chlorinated benzotriazole.
Fire retardant described in technique scheme is two (2, the 3-dibromopropyl) ether of tetrabromo-bisphenol and antimonous oxide; Two (2, the 3-dibromopropyl) ratio of quality and the number of copies between ether and antimonous oxide of described tetrabromo-bisphenol is three to one.
For the polyacrylic preparation method of flame-proof anti-aging of engineering machinery non-bearing gadget, comprise following preparation process:
A, weighing: the mass fraction of each component by ratio requirement is weighed;
B, to stir: each load weighted component is put into homogenizer and be stirred to and mix;
C, mixing granulator: the material mixed in step B is added in dual-screw pelletizer, by conveying, melting, mixing, exhaust and the smooth extruding pelletization of homogenizing;
D, cool, dry up, pelletizing and packaging: the granulation of extruding is cooled, dries up, pelletizing and packaging, obtain the flame-proof anti-aging polypropylene for engineering machinery non-bearing gadget.
After adopting technique scheme, the present invention has following positive effect:
(1) merge by the introducing of additional toughener is also good in formula of the present invention, improve the strength property of simple polypropylene material; The toughness of material is improved by the introducing of toughner; The weather-resistant performance of material is improved by the introducing of anti-aging weather resisting agent; And coupling agent facilitates the interface bond strength between toughener and matrix resin, and flow dispersion properties-correcting agent ensure that the dispersion of each component in this formula and mutually merges, and improves the processing fluidity of material; Increase fire retardant and achieve the fire-retardant of material, ensure that equipment and life safety.
(2) the polyacrylic density of gained of the present invention is low, only at 1.4g/cm
3left and right, well below the density of metallic substance, this polypropylene disposablely can obtain final gadget expeditiously by injection moulding, and the cost of gadget and weight are all lower than the gadget that metallic substance is obtained; And the good flame resistance of gadget, manufacture with assembly and disassembly operations all simple and easy to do; On the other hand, gained gadget and other material or when colliding noise little, also recoverable, the feature of environmental protection is better than metallic substance; And general soda acid rainwater can be tolerated, dust silt, its erosion resistance than metallic substance is better, and the life-span is longer.
