Description
Technical field
The present invention relates to technical field of polymer materials, particularly to a kind of modified polylactic acid composite material and preparation side thereof
Method and application.
Background technology
Polylactic acid (PLA) is replacing of renewable (bio-based synthetic resin) and biodegradable important petroleum base resin
For material, in recent years, it is researched and developed by more scientific research personnel.The environmental protection characteristic of lactic acid composite material makes it
Having broad application prospects, but poly-lactic acid material still has disadvantages that, as density is high, intensity is low, thermo-labile, facile hydrolysis etc.,
Limit polylactic acid greatly and replace other petroleum-based plastics materials application existing popularization.
During with galss fiber reinforced resin, owing to glass fibre and resin exist the most not on micro interface
Compatible phenomenon, the existence of micron-scale phase separation causes the overall performance of composite to be difficult to promote, therefore, ensure glass fibre with
Fully dispersed between fiber open, and be evenly distributed in resin it is critical that.Particularly when glass fiber diameter is less,
When modified polylactic resin, dispersion and the distribution of glass fibre is just more difficult to accomplish ideal, is mainly reflected in glass fibre and resin
Affinity between interface is difficult to promote, and therefore the overall performance of composite cannot improve substantially.Meanwhile, the diameter of glass fibre
Again can not be too big, although the glass fibre crossing major diameter is good with the affinity of resin boundary surface, but diameter is the biggest, and glass fibre increases
Strong effect is the poorest.During it addition, be modified polylactic acid, the filler of use generally is mineral filler, and density is relatively big, raw
The density of the lactic acid composite material of output increases accordingly.How the shortcoming existed for above-mentioned prior art, utilize diameter model
Enclose less glass fibre to strengthen polylactic acid, produce a kind of heat-resist, mechanical strength is high, tensile property good, density
Less modified polylactic acid composite material becomes current problem demanding prompt solution.
Summary of the invention
It is an object of the invention to provide a kind of heat-resist, mechanical strength is high, tensile property good, the less modification of density gathers
Lactic acid composite.
Another object of the present invention is to provide the manufacture method of above-mentioned modified polylactic acid composite material.
The present invention is achieved by the following technical solutions:
A kind of modified polylactic acid composite material, it is characterised in that: by weight, described modified polylactic acid composite material include with
Lower component:

The diameter of high-strength glass fibre is less than 5um, and glass fiber-reinforcing effect is preferable, but owing to its diameter is the least,
Dispersion and distribution more difficulty time modified, the lifting of the affinity between fiber and resin boundary surface is difficult to improve, corresponding composite wood
The overall performance of material will be unable to improve；When the diameter of high-intensity fiber is more than 10um, though can disperse when modification and reason is compared in distribution
Think, but fiber-reinforcing effect be substantially not as the little high-strength glass fibre of diameter, so, choose a diameter of 5～10um high-strength
Glass fibre is the most suitable.
Inorganic filler has the hollow structure of closing, by its fine dispersion in polylactic resin, it is possible to achieve
The multi-functional of the plastic obtained eventually, as reduced the density etc. of polylactic acid, it can also reach as inorganic filler simultaneously
Basic function, as increased the thermostability of poly-lactic acid material, mechanical strength and hot strength to a certain extent.Through experiment meaning
Outer discovery, when the compounding ratio of the quality of hollow glass micropearl and hollow ceramic microspheres is 1:4～1:1, the polydactyl acid made
The mechanical performance of composite, hot strength, thermostability are more preferable compared with the inorganic filler that other ratios of equal quality form, and work as
Above-mentioned quality compounds than for the mechanical performance of lactic acid composite material described during 1:3～1:1.5, hot strength, the changing of thermostability
It is apt to become apparent from.
