Description
Technical field
The present invention relates to plastic modified material technical field, particularly relate to a kind of fire retardant plastic of extrusion moulding of motor bellows material modified and preparation method thereof.
Background technology
The raising of people's consuming capacity brings developing rapidly of automobile industry; wherein particularly rapid with increasing of 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 of traveling on road should resist pole cold pole hot weather, the safety of driver and passenger can be protected again.Motor bellows commonly used by automobile, and motor bellows is mainly by import before, and cost is high and the production cycle is long; 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 carried out large quantifier elimination and technological improvement.
Motor bellows is applied to automotive wire bundle, general employing plastics (PA, PE, PP, PVC) corrugated tube, above-mentioned often kind of corrugated tube has self relative merits, thermotolerance as PVC material is not good, and the corrugated tube mechanical property that the corrugated tube that PP or PE material is made is made than PA almost, but will be better than PA corrugated tube in product stability and water-absorbent.
Because motor bellows all has higher requirement to the resistance toheat of plastic material, cold tolerance and flame retardant properties, therefore, need the defect for prior art badly, a kind of respective shortcoming overcoming existing plastic film capicitor is provided, there is plastic modified material of good cost performance and preparation method thereof.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, and provide a kind of fire retardant plastic with the extrusion moulding of a kind of motor bellows of heat-resisting, cold-resistant, flame retardant properties material modified.
Another object of the present invention is to for the deficiencies in the prior art, and the preparation method providing a kind of fire retardant plastic with the extrusion moulding of a kind of motor bellows of heat-resisting, cold-resistant, flame retardant properties material modified.
