Abstract
The present invention relates to a kind of preparation method for having high surface hardness and strong mechanical performance PP materials concurrently, its preparing raw material includes：45 70 parts of polypropylene；Continuous 20 30 parts of roving glass fiber；5 20 parts of melamine cyanurate；Double 5 20 parts of the diphenyl phosphoesters of resorcinol；3 10 parts of compatilizer；0.4 2.2 parts of antioxidant；0.5 3 parts of lubricant；5 10 parts of white oil；225 parts of cobalt of ethyl hexanoate；0.3 0.5 parts of copper resistant agent.The present invention adopts novel built halogen-free flame retardants, and flame retarding efficiency is very high, and the interpolation of the fire retardant does not result in material mechanical performance decline.The PP composites of the present invention have high surface hardness and strong mechanical performance concurrently, while the fire resistance of material is good, reach V0 levels.The PP composite material of the present invention can replace the materials such as traditional fire-retardant PA, flame-proof ABS, flame-retardant PBT, with higher ruggedness and adaptability, with preferable application prospect.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically, is that one kind has high surface hardness and high mechanical property concurrently
The preparation method of the PP materials of energy.
Background technology
Polypropylene (PP) is a kind of crystalline polymer of compound with regular structure, is white pellet, the heat of tasteless, nontoxic, light weight
Plastic resin.Polypropylene have good mechanical performance, without toxicity, density is relatively low, can be resistant to thermally and chemically medicine, easily into
The characteristics such as type processing, and its price is relatively cheap, is widely used in the industries such as electronics, machinery, article of everyday use.Polyolefine material
Thermal oxidation process cause chain off line reason to carry out by typical free radical, in this course, hydroperoxides are oxygen
Change the intermediate of reaction, it continues to resolve into free radical, causes again further thermal oxide.But, hydroperoxides selfdecomposition
Process into free radical needs at a relatively high energy, this process only can just carry out at a higher temperature.However, in some gold
In the presence of category ion such as Fe, Co, Mn, Cu etc., even if at ambient temperature, as the catalysis of these transition metal ionss is made
With hydroperoxides can resolve into free radical quickly, accelerate polyolefinic oxidation.On the other hand, polypropylene itself exists and lacks
Point, material surface hardness be not high, and particularly fire proofing can more reduce material due to the addition of fire retardant and other additives
Case hardness, causes the easy scratch of product, abrasive phenomenon.
Chinese patent 200910193699.7, discloses a kind of copper toxicity-resistant glass fiber reinforced polypropylene composite material and its preparation
Method, the polypropylene of the invention and glass fibre interfacial adhesion are strong, with excellent in mechanical performance, without floating fine, heat-proof aging and
The advantage of anti-copper evil property.Chinese patent 200510026763.4, discloses a kind of fiberglass reinforced of high thermo oxidative aging performance and gathers
Propylene material, it are the polypropylene, glass fibre, stabilizer DSTP, stabilizer 3114, steady being grafted by polypropylene, maleic anhydride
Determine the preparation of agent 618, the features such as which has low cost, every excellent in mechanical performance, thermo oxidative aging performance is excellent.Chinese patent
201410426273.2, disclose a kind of glazed flame-retardant scratch-resistant polypropylene composition and preparation method thereof, described bloom
The fire-retardant scratch-resistant polypropylene composition in pool is composed of the following components by weight percentage：Polypropylene 91-95 parts, MCA1-2 parts, resistance
The auxiliary agents such as combustion synergist 0.5-1, compatilizer 2-3 parts, silicone master batch 1-1.5 part, antioxidant 0.2-0.6, lubricant or pigment
0.2-0.4.But in prior art, have the PP composites of high surface hardness and strong mechanical performance with regard to the present invention concurrently, at present also
Have no report.
Content of the invention
The purpose of the present invention is for deficiency of the prior art, there is provided one kind has high surface hardness and strong mechanical performance concurrently
The preparation method of PP composites.
For achieving the above object, the present invention is adopted the technical scheme that：
A kind of preparation method for having high surface hardness and strong mechanical performance PP composites concurrently,
The PP composites are to be prepared by the raw materials in：
The preparation method comprises the steps：
(1) raw material is weighed according to proportioning, take polypropylene and mix homogeneously with white oil；
