Abstract
The present invention relates to a kind of PP composite materials for having both high surface hardness and strong mechanical performance, comprising: 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；2-5 parts of 2 ethyl hexanoic acid cobalt；0.3-0.5 parts of copper resistant agent.The present invention uses novel built halogen-free flame retardants, and flame retarding efficiency is very high, and the addition of the fire retardant not will cause material mechanical performance decline.PP composite material of the invention has both high surface hardness and strong mechanical performance, while the flame retardant property of material is good, reaches V0 level.PP composite material of the invention can replace traditional fire-retardant PA, flame-proof ABS, and the materials such as flame-retardant PBT have higher durability and adaptability, with good application prospect.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically, being that one kind has both high surface hardness and high mechanical property
The PP composite material of energy.
Background technique
Polypropylene (PP) is a kind of crystalline polymer of compound with regular structure, for white pellet, tasteless, nontoxic, light heat
Plastic resin.Polypropylene possess good mechanical performance, without toxicity, density is lower, can be resistant to thermally and chemically drug, be easy into
The characteristics such as type processing, and its price is relatively cheap, is widely used in the industries such as electronics, machinery, daily necessities.Polyolefine material
Thermal oxidation process be by typical free radical cause chain off line reason carry out, in this course, hydroperoxides are oxygen
Change the intermediate of reaction, it continues to resolve into free radical, causes further thermal oxide again.But hydroperoxides selfdecomposition
Quite high energy is needed at the process of free radical, this process only just can be carried out at a higher temperature.However, in certain gold
In the presence of belonging to ion such as Fe, Co, Mn, Cu, even if at room temperature, since the catalysis of these transition metal ions is made
With hydroperoxides can resolve into free radical quickly, accelerate the oxidation of polyolefin.On the other hand, polypropylene itself, which exists, lacks
Point, material surface hardness is not high, and especially fire proofing can more reduce material due to the addition of fire retardant and other additives
Surface hardness, the phenomenon that causing product easily to scratch, abrade.
Chinese patent 200910193699.7 discloses a kind of copper toxicity-resistant glass fiber reinforced polypropylene composite material and its preparation
Method, the polypropylene and glass fibre interfacial adhesion of the invention are strong, there is excellent in mechanical performance, without floating fine, heat-proof aging and
The advantages of anti-copper evil property.Chinese patent 200510026763.4, the fiberglass reinforced for disclosing a kind of highly resistance thermal-oxidative aging property are poly-
Propylene material, it is the polypropylene being grafted by polypropylene, maleic anhydride, glass fibre, stabilizer DSTP, stabilizer 3114, steady
Determine the preparation of agent 618, has the characteristics that at low cost, every excellent in mechanical performance, thermo oxidative aging performance are excellent.Chinese patent
201410426273.2 disclosing a kind of glazed flame-retardant scratch-resistant polypropylene composition and preparation method thereof, the bloom
The fire-retardant scratch-resistant polypropylene composition in pool is composed of the following components by weight percentage: 91-95 parts of polypropylene, MCA1-2 parts, resistance
Fire the auxiliary agents such as synergist 0.5-1,2-3 parts of compatilizer, 1-1.5 parts of silicone master batch, antioxidant 0.2-0.6, lubricant or pigment
0.2-0.4.However the PP composite material of high surface hardness and strong mechanical performance is had both about the present invention in the prior art, at present also
It has not been reported.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings in the prior art, provide one kind to have both high surface hardness and strong mechanical performance
PP composite material.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of PP composite material having both high surface hardness and strong mechanical performance, the PP composite material are by following weight
The raw material of part is made:
Further, the PP composite material is to be made from the following raw materials in parts by weight:
Further, the PP composite material is to be made from the following raw materials in parts by weight:
Further, the polypropylene melt index is 20g/min.
Further, the compatilizer is selected from maleic anhydride, methyl methacrylate, maleic anhydride inoculated polypropylene, Malaysia
Acid anhydrides graft phenylethene-ethylene-butylene, Styrene block copolymer, metering system acid grafted ethylene-acrylic-butadiene ternary
