Description
Technical field
The present invention relates to the plastic modified material technical field, it is material modified and preparation method thereof to relate in particular to fire retardant plastic that a kind of extrusion moulding of motor bellows uses.
Background technology
The raising of people's consuming capacity brings developing rapidly of automobile industry; wherein particularly rapid with increasing of the car of riding instead of walk; the design of dolly and the selection of each parts should economy and beautiful appearance; safety and environmental protection again; make the dolly that travels on road should resist utmost point cold pole hot weather, can protect driver and passenger's safety again.Automobile is commonly used to motor bellows, and mainly by import, cost height and production cycle are long for motor bellows before; Along with the raising of domestic automobile component manufacturing technology, break away from the limitation to automobile component and engine intake, domestic expert and engineers have been carried out a large amount of research and technological improvement.
Motor bellows is applied to automotive wire bundle, general plastics (PA, PE, PP, the PVC) corrugated tube that adopts, above-mentioned every kind of corrugated tube has the relative merits of self, thermotolerance as the PVC material is not good, and the corrugated tube that PP or PE material are made is more a little bit poorer than the corrugated tube mechanical property that PA makes, but is being better than the PA corrugated tube aspect product stability and the water-absorbent.
Because motor bellows all has higher requirement to resistance toheat, cold tolerance and the flame retardant properties of plastic material, therefore, need the defective at prior art badly, a kind of shortcoming separately that overcomes existing plastic film capicitor is provided, has plastic modified material of good cost performance and preparation method thereof.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, and the fire retardant plastic that provides a kind of extrusion moulding with a kind of motor bellows of heat-resisting, cold-resistant, flame retardant properties to use is material modified.
Another object of the present invention is at the deficiencies in the prior art, and the material modified preparation method of fire retardant plastic who provides a kind of extrusion moulding with a kind of motor bellows of heat-resisting, cold-resistant, flame retardant properties to use.
The present invention is achieved through the following technical solutions.
The fire retardant plastic that a kind of extrusion moulding of motor bellows is used is material modified, and in weight part, it is made up of following raw material:

The PA6(formal name used at school: polymeric amide-6, trade(brand)name: nylon 6) density of resin is 1.13g/cm
3, fusing point is 215 ℃, tensile strength (MPa)＞60.0, elongation (%)＞30, flexural strength (MPa) 90.0, notched Izod impact strength (KJ/m
2)＞5.The heat decomposition temperature of PA6 is greater than 300 ℃.The PA6 resin has high thermostability, and the fire retardant plastic that the extrusion moulding of a kind of motor bellows of preparation is used is material modified to have the better heat-resisting performance.
The Chinese of LLDPE is LLDPE (Linear Low-Density Polyethy-lene), the LLDPE resin has excellent environmental stress crack resistance, low-temperature impact resistance and anti-warpage properties, the fire retardant plastic that the extrusion moulding of a kind of motor bellows of preparation is used is material modified to have cold tolerance preferably.
PA12(formal name used at school: polymeric amide 12, trade(brand)name: nylon 12), the relative density of PA12 is 1.01～1.02, and fusing point is 178 ℃, and tensile strength is 50～64MPa, flexural strength is 74MPa, socle girder (breach) shock strength is 4～6kJ/m, and volume specific resistance is 1014 Ω cm, and dielectric strength is 17kV/mm, heat-drawn wire (1.82MPa) is 54.5 ℃, and PA12 has wear resistance, self lubricity and snappiness preferably.The fire retardant plastic that PA12 uses the extrusion moulding of a kind of motor bellows of preparation is material modified to have tensile strength, flexural strength, shock strength and snappiness preferably.
The formal name used at school of EPDM-G-MAH is the maleic anhydride graft terpolymer EP rubber, PA6 has advantages such as high strength, wear-resisting, oil resistant and chemical resistance corrosion, but because PA6 low temperature and shortcomings such as the dry state impact property is poor, notched Izod impact strength is low, water-intake rate height have limited its application.Terpolymer EP rubber (EPDM) good springiness, mechanical property height, corrosion-resistant, ventilative and low temperature resistant and heat-resisting, anti-ozone, UV resistant and water-fast, so can be used for the toughness reinforcing and low temperature modification of PA6, because PA6 is polar polymer, incompatible with EPDM, therefore adopt maleic anhydride (MAH) grafting EPDM(EPDM-G-MAH) toughness reinforcing PA6, the weight part of the EPDM-G-MAH that the present invention uses and the weight part of PA6 are through testing the optimum range that draws many times, can effectively improve the toughness of PA6, improve its mechanical property.
The formal name used at school of DBDPE is decabrominated dipheny base ethane, is a kind of environmental protection additive flame retardant, its bromine content height, and thermostability is good, and anti-ultraviolet property is good, exudative low than other bromide fire retardant.DBDPE does not produce poisonous many bromos dibenzo dioxan (DBDO) and PBDF (DBDF) when cracking or burning, meet Europe fully about the requirement of Dioxins regulations with its fire-retardant material, and environment is not worked the mischief.DBDPE does not have any toxicity, can not produce any teratogenecity to biology yet, and aquatic organism such as fish etc. is had no side effect, and meets environmental protection requirement.DBDPE is quite stable in the system of using, and can recycle with its fire-retardant thermoplastics, meets the demand for development that reclaim the waste household appliances product in Europe.The disadvantageous effect of the fire retardant material performance of DBDPE is little than the conventional flame retardant decabromodiphynly oxide, and light fastness is good.The fire retardant plastic that DBDPE uses the extrusion moulding of a kind of motor bellows of preparation is material modified to have flame retardant properties preferably.
