Description
Technical field
The invention belongs to technical field of composite materials, bumper matrix material being specifically related to a kind of super high impact strength and preparation method thereof.
Background technology
Bumper be arranged on automobile foremost and rearmost end, in vehicle modeling style, play vital effect, it can examine the artistic style of disengaging car load external decoration.Good collision bumper can make user feel pleasing, obtains beautiful enjoyment.Bumper is one of important exterior trimming parts of automobile, and regardless of size, the moulding of automobile, collision bumper always stands in the breach becomes the object that in hairstylist's hand, emphasis is moulded, and handsome in appearance is bright spot and the attraction of car load.At secure context, bumper plays an important role.When automobile collides, it plays absorption energy, alleviates collision, the effect of safety precaution, is the important component part of Hyundai Motor safeguard construction, effectively can alleviate loss of life and personal injury and car breakdown degree.Meanwhile, it is again that in the application component of plastics on automobile, consumption is maximum, volume is maximum, the representational plastic items of most.
In the performance history of collision bumper, answer following several principles: 1. active safety, namely must meet using function to greatest extent, the mounting height of collision bumper should meet regulation (safe and reliable, reasonable in design); 2. passive safety, when namely colliding, collision bumper will have good energy absorption characteristics; 3. harmonious with vehicle modeling in external styling, color and texture, one integrated mass.Correctly selection material, must meet the requirement of 3 aspects: 1. good use properties; 2. excellent processing performance; 3. rational cost.At present, the material of collision bumper selects modified polypropene usually, and it should meet following essential characteristic: 1. thermotolerance 80 1 100 DEG C; 2. shock strength 30 1 80kJ/m2; 3. tensile strength 29 1 39MPa; 4. good moldability, excellent weather resistance and hard is good.
When China's automobile industry regulation speed per hour is 40 kilometers of shocks, collision bumper should be not damaged.This just requires that modified polypropylene material should have feature that is shock-resistant, good toughness.Because China's various places weather difference variation is very large, just require that automobile bumper material will have good weathering resistance.Common injection stage polypropylene simple beam impact strength is generally 2.2 ~ 2.5kJ/mz (23 DEG C).In order to improve its shock strength, normally use EPR, EPDM, sBs or other thermoplastic elastomer and polypropene blended, particularly EPDM is similar to Polypropylene structural, and consistency is better, and the amplitude that modified polypropylene shock strength improves is maximum.Beijing Chemical Research Institute EPDM and polypropylene blending modifiedly successfully develop bumper special material, when its simple beam impact strength reaches 72kJ/, other performance index all reach the level of same kind of products at abroad, and this kind of PP Pipe Compound is applied to the production of collision bumper of charade car, car Santana, favorite Song Hua River car in large quantities.The polypropylene of Jinling Petrochemical Co.'s development gets rid of the modified polypropene bumper special material of P side FE blending toughening, normal temperature Analysis of A Cantilever Beam Under notched Izod impact strength reaches 50OJ/m, through Kunshan, Danyang etc., the experiment of relevant producer injection moulding collision bumper proves, this kind of material producing process is steady, after the collision bumper demoulding, physical dimension is stablized.More domestic scientific researches and production unit have developed high workability, high impact polypropylene PP Pipe Compound, are applicable to very much producing high-grade car collision bumper, performance oneself reach the level of same kind of products at abroad.Such as, Shanghai Communications University's application dynamic vulcanization technology have developed the polypropylene type material of rubber plastic blend, Jiangsu oilfield Jiangdu engineering plastics factory application polyolefin elastomer (POE) carries out toughening modifying to polypropylene, successfully produces collision bumper alloy material.Domestic (comprise and introduce joint vehicle) all kinds of medium and high classes car, economy sedan, light card, minicar bumper special material 80% domesticize.
