Description
Technical field
The invention belongs to automotive material technical field, particularly relate to a kind of weather resistance environmental protection type automobile bumper material.
Background technology
Polypropylene is polymer nontoxic, that odorless, tasteless milky are highly crystalline, density only has 0. 90--" 0. 91g/
Cm3, is one of kind the lightest in current all plastics.It is particularly stable to water, and the water absorption rate in water is only 0. 01%,
Molecular weight about 80,000 one 15 ten thousand.Good moldability, but because shrinkage factor is big (being 1% ~ 2.5%). thick article easily caves in, right
The higher part of some dimensional accuracies, is difficult to reach requirement, product surface good luster, it is easy to coloring.
Temperature and loading speed are the biggest to polyacrylic Toughness.When temperature is higher than vitrification point, impact failure
In ductile rupture, it is brittle fracture less than vitrification point, and impact value significantly declines.Improve loading speed, can make
The temperature that ductile rupture changes to brittle fracture rises.Polypropylene has the flexural fatigue resistance of excellence, and its goods are at normal temperatures
Bent 106 times and do not damage.But under room temperature and low temperature, owing to the molecular structure regularity of itself is high, so shock resistance
Intensity is poor.The most prominent performance of polypropylene is exactly flexural fatigue resistance, is commonly called as polypropylene (PP).
The Main way of existing automotive material technology development is environmental protection and lightweight.Replace metal with plastics, can not only subtract
Light car weight, reduces oil consumption and hydrocarbon emission but also can improve dynamic property, adapts to adverse circumstances, strengthens safety.
Due to plastics recoverable, thus reduce the consumption of resource, be finally that automobile obtains more in safety and cost two aspect
Breakthrough, simultaneously also design, for automobile appearance, the condition of providing convenience.In automotive plastic, the consumption of polypropylene (PP) is
Greatly, growth rate is the fastest.PP has become as the primary raw material of bumper, due to bumper be that a kind of surface area is relatively big, shape relatively
For complicated thin-walled large-sized structural component, can be affected by factors such as impacts during use, therefore bumper material needs higher
Mobility, rigidity, toughness, thermostability etc., also to have good dimensional stability and ageing resistace.But owing to general PP deposits
Big, product size poor stability, easy buckling deformation in shrinkage factor；Low-temperature flexibility brittle failure poor, easy；Heat-resisting, photooxidation aging property is poor
Etc. shortcoming, it is impossible to meet Hyundai Motor, all multi-parts of household electrical appliances, it is therefore necessary to general PP material is modified.
Summary of the invention
